  1A and 1B are respectively two perspective views of an exemplary embodiment of a portable lighting device 10 according to the present device. 1C and 1D are two perspective views of an exemplary embodiment of a portable lighting device 10 according to the present device having a mounting bracket 60. FIG. FIGS. 2A-2D are various views of the exemplary lighting device 10 of FIGS. 1A-1D, showing the pivotable lighting device head 40 of the lighting device moved to various alternating positions. FIGS. 3A-3E are a side view, a top view, a bottom view, a front end view, and a rear end view, respectively, of the exemplary lighting device 10 of FIGS. 1A-1D.

  The portable lighting device 10 comprises a lighting device body 20 and has a front end 12 and a rear end or tail end 14, between the front end 12 and the tail end 14. The longitudinal axis 16 is defined. The illuminator body 20 includes a housing 30 and an illuminator head 40 pivotally attached to the housing 30 by a hinge or pivot 36 including one or more hinge or pivot pins 37. The housing 30 preferably has an internal cavity for receiving a power source, for example a battery, which can be accessed by removing the tail cap 24. The lighting device body 20 also includes an actuator 22 for selectively controlling the light source or a plurality of light sources of the lighting device 10 and has a lens 26 facing rearward and also the rear end of the lighting device body 20 14 has a removable tail cap 24 that closes 14.

  The pressure actuator 22 on the lighting device body 20 actuates an electrical switch inside the lighting device 10, for example inside the housing 30, so that if the lighting device head 40 is directed forward: A first light source contained in the illuminator head 40 is controllably energized to produce light in a forward direction substantially parallel to the axis 16 and is positioned behind the rearward facing lens 26; Two light sources are controllably energized to generate light in a rearward direction substantially parallel to the axis 16.

  The illuminator head 40 includes a head housing 42 that includes two support arms 44. The two support arms 44 extend rearwardly from the head housing 42 for connection with the hinge or pivot 36 so that the lighting device head 40 is pivotable relative to the lighting device housing 30. . The illuminator head 40 pivots up and down, for example, at least about 90 degrees with respect to the illuminator housing 30 and the longitudinal axis 16. Although exemplary alternate positions of the illuminator head 40 at about +45 degrees, about +90 degrees, about -45 degrees, and about -90 degrees of pivoting are illustrated, the illuminator head portions 40 have approximately about pivoting. It may be moved to and placed at any desired alternative position between +90 degrees and about -90 degrees.

  A lens 46 is provided at the front end 12 of the illuminator head 40 for passing light generated by the internal light source. The lens 46 is held by the lens ring 48 on the head unit housing 42. The lens ring 48 is threaded so as to be removable or permanently attached, for example by means of a press fit, an adhesive, ultrasonic welding or another suitable means. The light emitted by the light source of the illuminator head 40, which is emitted through the lens 46, is typically an illumination beam, for example, a relatively thin or spot-like beam that is common to portable illuminators.

  The lens 26 is proximal to the rear end 14 of the lighting device 10 to pass light generated by the light source in the housing 30 in a generally rearward direction, for example, substantially parallel to the longitudinal axis 16. It is provided. In some applications, the light emitted back from lens 26 provides a safety beam or beacon. By means of this safety beam or beacon, the position of the lighting device 10 and thus of the user and / or the wearer of the lighting device 10 is determined. One common safety lighting situation involves firefighters who usually have blue safety beacons. Blue safety beacons emit significant light at the end of the red-orange-yellow spectrum and are somewhat easier to identify in the fire and smoke environment. The light emitted through the lens 26 is preferably a relatively broad or radial beam, such that the light is visible over a relatively wide range of directions and is also optional May be the desired color or colors of

  Clips 50, for example elongated clips 50, are provided such that the lighting device 10 can be attached, for example clipable, to an object such as a pocket, a belt, a vest, a tool carrier, a structure or other object. The clip 50 includes an elongated clip arm 52 extending longitudinally along the exterior of the lighting device body 20, eg, the housing 30, with the clip end 52N closely adjacent to the lighting device body 20. The clip 50 is preferably formed of an elastic or spring material so that the clip arm 52 can be moved out of the luminaire body 20 and, when released, with the clip arm 52 Anything that is between it and the lighting device body 20 tends to press against the lighting device body 20, thereby attaching the lighting device 10 relatively firmly to that object.

  Preferably, the clip 50 is configured to rotate about the illuminator body portion 20 and the longitudinal axis 16 at least over a limited rotational range. This limited range of rotation is, for example, a rotation of about 45 degrees or less, for example, preferably about 90 degrees from the axis of the hinge or pivot 36, preferably exactly opposite the actuator 22 and from its central position. It is about ± 22.5 degrees in either direction. In one exemplary embodiment, the clip 50 is rotatable about the housing 30 by about ± 15 degrees, and the end of the clip 50 is attached to the post at the front end of the housing 30, It is held on the housing by the end cap 34. Thus, as clip 50 moves (rotates) relative to housing 30, distal end 52 N of clip arm 52 moves across an arcuate path adjacent the outer surface of housing 30.

  A significant advantage is seen to be the result of providing two degrees of freedom for positioning the illuminator head 40 relative to the housing 30. One degree of freedom is due to the pivotability of the lighting device head 40 with respect to the housing 30, and a second degree of freedom is due to the freedom of rotation of the clip 50 relative to the housing 30.

  For example, if the user attaches the lighting device 10 to the pocket or other feature with a clip such that the lighting device body 20 is generally vertical in front of the user, the lighting device head 40 will forward or forward the light. -May be pivoted up and down, for example towards the work place, and furthermore, the lighting device 10 uses the relative rotational freedom of the lighting device housing 30 and the clip 50 May rotate left or right. Furthermore, when the light source producing light through the lens 26 facing backwards is energized with the lighting device 10 so attached to a person with a clip, the light emitted through the lens 26 is standing by the user It is directed downwards so as to illuminate the surface, thereby improving the safety of movement.

  A clamp or bracket 60 may be provided for use in the lighting device 10, whereby the lighting device 10 is attached to the edge of a hard object such as, for example, a firefighter's helmet, another helmet, a hard hat, etc. It may be worn or worn. The mounting bracket 60 is preferably secured in a shape of the clamp member 62, for example, the edge of the object may be inserted, for example by tightening one or more clamp screws 63. In some cases, it includes a C-shaped clamp member 62 having an open side. The clamping member 62 is preferably attached to or connected to the lighting device 10 at its end remote from the clamping screw 63.

  Thus, the lighting device 10 is supported by the object to which the mounting bracket 60 is attached. In a typical application, the lighting device 10 is mounted at the lower edge of a helmet or other headgear, usually at a position close to the side of the user's head, whereby the longitudinal axis 16 is generally Near horizontal, pointing forward and backward, whereby light emitted through the lens 46 is generally directed forward of the user, and light emitted through the lens 26 is generally directed backward of the user There is.

  The preferred embodiment of the clamp member 62 has a base 64 at its end distal from the clamp screw 63. A pair of bracket arms 66 extend outwardly from the base 64 to define a space or passage therebetween. On the inward facing surface of each bracket arm 66 near the intersection of each bracket arm 66 and the base 64 there is a respective groove 67. Together, the two grooves 67 define a space sized and shaped to receive the elongated clip arm 52 of the clip 50 so that the mounting bracket 60 slips on the clip arm 52 and the clip arm 52 The mounting bracket 60 and the lighting device 10 may be conveniently mounted and separated.

  In normal use, the mounting bracket 60 is considered to be mounted to be held on a helmet or other headgear, while the lighting device 10 inserts the clip arm 52 of the clip 50 into the groove 67 of the bracket 60 Attached and removed by disengaging from the groove 67. The clip arm 52 can be held firmly in the groove 67 of the bracket 60, passes through the space between the relatively wide portion 52B and the bracket arm 64, thereby allowing the clip 50 to be separated therefrom It should be noted that it has a relatively narrow end 52N that is adapted to

The battery may be installed and removed through the rear end of the internal cavity when the tail cap 24 is removed, for example when it is unscrewed. A seal ring 30S, for example an O-ring, is disposed in the circumferential groove 30G around the externally threaded end of the housing 30. The annular contact ring 30R is located behind the threaded end of the housing 30, eg, the housing 30, for making electrical contact with the outer ring of the contact spring 24S, which is disposed and held in the inner recess of the tail cap 24. Seated at the end.

  The circular opening in the circular feature 30C on the top of the housing 30 receives the switch plunger 22P covered by the elastic switch boot or cover 22C. The switch boot 22C is held in place by a retaining ring 22R which may be fixed by adhesive, ultrasonic welding or another suitable fixing means. When the switch boot 22C is pressed, the switch boot 22C and the plunger 22P move toward the inside of the housing 30 to press against the electric switch 208 mounted on the electric circuit board 200 in the housing 30. Activate.

  The openings at the front end of the housing 30 provide access for the insertion and assembly of the various components into the interior of the housing 30. Among these, there is the electronic circuit board 200 in a plane substantially parallel to the top of the housing 30, so that the switch 208 on the electronic circuit board 200 is activated, so that the switch plunger 22P are arranged below, and light emitting diodes (LEDs) L1, L2 are in a desired position with respect to the optical element, for example the reflector 26R. The reflector 26 R is behind the lens 26 disposed in the D-shaped rearwardly facing opening on the housing 30. Typically, the switches 22, 208 serve to control all of the on / off and operating mode selections for the lighting device 10.

  The connection between the circuit board 200 and the battery in the housing 30 is via the conductors 202 and 210 attached to the respective contact pads on the circuit board 200, eg soldered or crimped, etc. It will be. The front battery contact 202 has a C-shaped hook 202T at its top end. The C-shaped hook 202T is configured to be attached at the front edge of the circuit board 200, for example, near the center of this edge, and soldered in place to the contact pad at this position, the housing It has a central contact in the shape of a D for electrical contact with the front terminal of the 30 batteries, for example the positive (+) of the battery. The elongated conductor 210 has a C-shaped hook 210T at its front end. The C-shaped hook 210T is configured to be attached at the front edge of the circuit board 200, for example, a portion adjacent to the contact 202 near the center of this edge but being insulated, at this position , Soldered into place. The elongated conductor 210 is slightly offset at its rearward end 210R that closely fits between the contact ring 30R and the inner wall of the threaded end of the housing 30, optionally with solder Attached or welded together. Thereby, when the battery is in the housing 30 and the tail cap 24 is tightened on the housing 30, between the circuit board 200 and the rear terminal of the battery, for example, its negative (-) terminal normally. Electrical connection is provided via the conductor 210, the contact ring 30R, and the contact spring 24S.

  The housing 30 is arranged in an oppositely rectilinear manner in order to receive the fixing means 37, for example the pivot pin 37, to provide a hinge or pivot 36 for pivotally supporting the lighting device head 40. It has a hole 36H. The pair of O-rings 36S provide both a seal and a source of friction to hold the illuminator head 40 at the desired pivot position pivoted relative to the housing 30 by the user. Each trim cap 37C is snapped into place to cover the exposed end of pivot pin 37, or otherwise fixed in place by, for example, an adhesive or ultrasonic welding.

  Each of the pair of opposing conductors 204 has a respective C-shaped hook 204T at its top end. The C-shaped hook 204T is configured to be attached near the side edge of the circuit board 200, for example, the front end of its respective side edge, and in this position, each, for example, in position It is soldered. Each conductor 204 has a planar portion with an annular ring or bore therein extending downwardly and adjacent to the inner surface of the housing 30, the annular ring or bore being the respective bore of the housing 30. It is in line with section 36H. When pivot pin 37 is in place, each conductor 204 serves as one end of a slip ring connection with the corresponding annular ring and hole of the respective conductor 220. Conductor 220 extends rearward along the inner surface of support arm 44 of illuminator head housing 42. Each pivot pin 37 provides an electrical connection between the annular rings of conductor 202 and conductor 220 respectively, thereby providing a pair of slip ring electrical connections through pivot axis 36. Thereby, power may be provided to the light sources of the illuminator head 40 past their pivots 36.

  The interface ring 39 fits in the opening in the front end of the housing 30 and receives the front end 38. Both the interface ring 39 and the front end 38 are held in the housing 30 by adhesive, ultrasonic welding or another suitable fixing means, whereby the circuit board 200 and the parts 202 of the circuit board 200, Hold 204, 210 in position within housing 30. The housing end 38 has a centrally located post 38P for receiving the annular mounting ring 54 of the clip 50. An O-ring 54S, disposed in a groove surrounding the post 38P, is supported against the annular mounting ring 54, thereby holding the clip 50 in the desired rotational position where the clip 50 is moved by the user. It is designed to provide a restraining force by friction. A grease or other lubricant may be applied to the O-ring 54S to allow it to move more easily while the frictional hold in place is maintained. The end cap 34 is fixed to the housing front end 38, for example by adhesive, ultrasonic welding or another suitable fixing means, so that the clip 50 is rotationally moveable on the housing 30 and It is intended to be permanently retained on the housing 30. Thus, the clip 50 is movable (rotatable) about the longitudinal axis 16 of the lighting device 10 with the elongate clip arm 52 of the clip 50 adjacent the outer surface of the housing 30.

  In the preferred embodiment, the rotational movement of the clip 50 is limited by the shoulder 38S of the front housing end 38. The shoulder 38S limits rotational movement of the short section 55 of the clip 50 that couples the annular mounting ring 54 to the elongate clip arm 52. The limitation of the rotational movement of the clip 50 can be in the range of more than about 90 degrees, but in normal embodiments rotation is about 45 degrees of rotation, or about 30 degrees of rotation if desired. It may even be limited. The limitation of the angle is defined by the angular position of the shoulder 38S, and the permitted rotation angle may also be substantially centered about 180 degrees rotated from the top side of the housing 30 and the lighting device 10. Note that it is preferable.

  Although preferred, optionally, the rotational movement of the clip 50 around the housing 30 is relatively symmetrical in both directions around a central position. This central position is at a position exactly opposite to the switch actuator 22 (e.g., a position rotated approximately 180 degrees from the switch actuator 22), thereby pushing the actuator 22 when the lighting device 10 is attached to a person or object Thereby, the switch actuator 22 may be actuated, for example turned on and off, and put in any available, programmable operating state. The actuator 22 is preferably a push button actuator responsive to being pushed radially towards the housing 30.

  The illuminator head 40 includes a head housing 42 having a circular opening at its forward end. The reflector 42R is fitted to the circular opening. The reflector 42R has a circular front end to which the lens ring 48 snaps, but alternatively, for example, if it has an external thread on which the lens ring 48 is attached by a screw. There is. The annular lens holder and seal 48R has a circumferential groove on its inner surface. The lens 46 fits in this circumferential groove. For example, the lens 46 and the holder 48R are held inside the lens ring 48 at the front end of the lens ring 48 by the inner circular flange. O-ring 46S provides a seal between reflector 42R and head housing 42.

  The reflector 42R is a curved interior having a shape normally configured to shape the light generated by the light source 43, for example the LED light source 43, centrally located at the base or at the rear end of this base It has a reflective surface. The LEDs 43 are substantially centrally located on the LED circuit board 42 L with printed wiring conductors thereon for electrically connecting the respective terminals of the LEDs 43 to the conductors 220. Each of the conductors 220 has a vent tab 220T at its forward end. The bent tab 220T is electrically connected to the conductor of the LED circuit board 42L, for example, by being soldered, and has a hole close to its rear end, which is in line with the hole 44H. ing. This hole is for providing slip ring contact between the exterior of the lighting device housing 30 and the extension arm 44 of the lighting device head 40 to form an electrical connection to the pivot pin 37 .

  The LED circuit board 42L may have a wide conductor on one side or both sides, and may have through holes filled with solder, and / or other thermal conductivity features, Thus, the thermal conductivity between the front surface of the LED circuit board 42L on which the LEDs 43 are mounted and the rear surface of the LED circuit board 42L is improved. Abutted against the rearward facing surface of the circuit board 42L is a heat spreader 42H having a relatively high thermal conductivity to further aid in the removal of the heat generated by the LED 43. Furthermore, the reflector 42R may be a material having a relatively high thermal conductivity to further assist the removal of the heat generated by the LED 43. Fastening means 42F engage holes in the back end of reflector 42R to attach LED circuit board 42L and heat spreader 42H to the back surface of reflector 42R. The rear surfaces of the reflectors 42R are preferably generally flat and preferably abut closely to one another. At the interface between the LED circuit board 42L, the heat spreader 42H and the rear surface of the reflector 42R, for example, thermal grease, silicone or other material to improve the thermal conductivity between them And other materials may be included.

  With circuit board 42L and heat spreader 42H attached to the rear end of reflector 42R, and lens ring 48 and lens 46 attached to the front end of reflector 42R, reflector 42R can Holes are inserted into the internal cavity of the head housing 42 in alignment with the respective holes 44H of the arms 44 and are retained within the internal cavity by additional securing means 42F2. Additional securing means 42F2 pass through holes in circuit board 42L and heat spreader 42H and engage holes in the rear surface of reflector 42R to pull reflector 42R into housing 42 and to reflect The vessel 42R is held in the housing 42. Optionally, an O-ring may be provided on each securing means 42F2 as a seal.

  Further details of the slip ring electrical connection of the pivot shaft 36 can be seen in cross section. Here, a respective pivot pin 37, for example a metal pin 37, formed at its shaft end is inside the housing 30 to hold the pivot pin 37 in the pivot 36, while the electrical circuit board An electrical connection is provided between the conductor 202 connected to 200 and the conductor 220 connected to the LED circuit board 42L. Also visible in the cross-sectional view are details of the arrangement of the contact ring 30R on the rear end of the housing 30 and the formation of the connection of the tail cap 24 with the contact spring 24S.

  Specifically, a side cross sectional view shows the circuit board 200, the switch 208 on the circuit board 200, the position of the switch 208 with respect to the flexible cover 22C of the actuator 22 and the plunger 22P, an optical element such as a reflector 26 shows the internal configuration within housing 30 with LEDs L1 and L2 on circuit board 200 for 26R and lens 26. FIG. Preferably, the switch 208 and its actuator are adjacent to the plunger 22P and the cover 22C and in a central position below the plunger 22P and the cover 22C. Also visible are when the illuminator head 40 is pivoted to a forward facing rotational position while the Hall effect sensor HS and the magnet 40M are in relatively close alignment, and The position of the Hall effect sensor or detector HS on the circuit board 200 and the position of the magnet 40 M on the rear wall of the lighting device head 40 when the portion 40 is pivoted upward by approximately 90 degrees, And their relative positions. These features are described below. The configuration of the mounting bracket 60 mounted on the clip 50 is also visible in some of the figures and is described below.

  6A and 6C are cross-sectional views of the exemplary lighting device of FIGS. 1A-1D, showing an exemplary embodiment of a safety lighting device feature of the lighting device, and FIGS. 6B and 6D, respectively, of the lighting device. It is an enlarged view of a detail. Light generated by the LEDs 43 of the illuminator head 40 is directed forward of the illuminator head 40 generally along the longitudinal axis 16 and the illuminator head 40 is pivoted about a hinge or pivot axis 36 When raised to about ± 90 degrees with respect to the longitudinal axis 16. Also, this light is preferably a relatively bright, relatively thin beam, for example a spot beam, for producing illumination light directed forward and in the direction in which the illuminator head 40 pivots. is there. Furthermore, a second light source L1, L2 is generated with light backwards, through an optical element, for example a lens 26, and in a generally backward direction, as defined, for example, by the longitudinal axis 16.

  Such backward-directed light is often generated to be a safety light device or safety beacon, such that a person behind the user of the light device 10 can view such safety beacons The position of the user can be specified. Common uses for such safety beacons are firefighters and emergency response first when it is difficult to find such users due to smoke, mist, fog and / or darkness For others who do. For firefighter users, safety beacons are often blue lights. The reason for this is that blue is distinguishable from the light produced by the fire, which is roughly the end of the yellow and red visible spectrum. For other users, other colors of the lighting device of the safety beacon may be generated. This color is, for example, red if a color that does not interfere with night vision is desired, or only a tracker with a device with night vision, for example only strategic personnel, can see the safety beacon If it is desired, it is even infrared (IR) light.

  To this end, the lighting device 10 comprises a light source generating light of two different colors and / or intensities, and an optical element for directing this light back. In one exemplary embodiment, the lighting device 10 includes a light source L1. The light source L1 is such that the light LB1 generated by the light source L1 is directed backwards towards the lens 26, through which the light of the safety beacon exits the illumination device 10 in a generally backwards direction , And mounted on the circuit board 200. The light source L1 is preferably an LED L1 packaged such that when mounted on the circuit board 200, the light LB1 is directed generally parallel to the surface on which the light source L1 is mounted. . This light passes through the space defined in the interior, into the generally parabolic semi-reflector 26R, onto the reflecting surface 26RS of this reflector 26R in order to deform the beam into incidence on the lens 26. Light from LED L 1, which does not rely, but is directed but incident on reflective surface 26 RS, tends to be directed to lens 26.

  The lens portion of the lens 26 is D-shaped, for example, substantially semicircular, and has a series of concentric, partially annular grooves 26G, for example, on its inner surface. This inner surface scatters the beam of light generated by the LED L1 into a relatively well defined but broad light beam LB1, whereby the safety beacon is at an angle behind the lighting device 10 It serves to make it converge so as to be visible over a relatively wide range. For this reason, the safety beacon LB1 is preferably, for example, a beam that is relatively radially like, rather than a narrow spot beam (the same is true for the light beam LB2).

  The annular grooves 26G of the lens 26 serve to spread the respective light beams LB1 and LB2 from each LED L1 and L2, preferably forming a Fresnel lens or at least approximating a part of the Fresnel lens , Arced in the lateral direction. The partially annular groove 26G may have a relatively steep slope, eg, substantially perpendicular to the plane of the lens 26, with one side or an arcuate surface of the groove, eg, an upwardly facing side or arcuate surface, being relatively steep. While the other side or the annular surface, for example, the downward facing side or the annular surface is inclined at an angle, for example, at various angles over a range of angles of about 40 to 50 degrees Preferably, the cross section is sawtooth-shaped and may be slightly concave so that the light passing through the lens 26 is dispersed to form the desired beams LB1, LB2.

  In the reflector 26R, the reflector 26R has a substantially semicircular opening at its wide end, for example, a D-shaped opening, and is semi-parabolic or other curve less than circular. In terms of having a substantially defined reflective surface 26RS, it may be referred to as a "semi-reflector". This arrangement is interpreted as being more space efficient and ensuring much of the high intensity light emitted by the LED when utilized with a suitable light source. The reflector 26R, for example, when installed in the housing 30, also has a semi-cylindrical projection on the front and a rear thereof. This protrusion fits into the lens 26, the circuit board 200, and the complementary recesses in the housing 30 to hold the reflector 26R in the desired position and orientation relative to the LEDs L1 and L2 on the circuit board 200. .

  The second light source again preferably comprises a second LED L2, for example mounted on the surface of the circuit board 200. In this mounting position, the second LED L2 is substantially at or near the focal point of the parabola 26RS ', the reflective surface 26RS of which defines a part. The LED L2 generates light generally directed away from the circuit board 200 so as to be primarily incident on the reflective surface 26RS of the reflector 26R. The reflective surface 26RS ′ is configured to receive the light emitted from the light source LED L2 and to form the light into a beam. This beam passes through the lens 26 back towards the lens 26 as a path of illumination of the radial beam, for example when the lighting device 10 is hand-held or mounted on the front of a person Are directed to

  Preferably, the reflective surface 26RS of the reflector 26L defines a portion of the parabola having a focal point or convergence point of the surface outside the space in the reflector 26R, whereby the circuit board is adjacent to the reflector 26R. A light source, such as LED L2, mounted at 200 emits light from a point substantially at or near the convergence point of parabolic reflective surface 26RS. The parabola is more fully illustrated by the surface 26RS and the dashed line 26RS ', where the surface 26RS is a portion of the parabola 26RS' that forms the reflective surface of the reflector 26R. The reflector 26R has an opening near its base through which the light generated by the LED L1 passes to the lens 26.

  The lens 26 can be held on the housing 30 by any suitable fixing means, such as, for example, a friction fit, an adhesive, ultrasonic welding or the like. Similarly, the reflector 26R can be held in its recess in the housing 30 by any suitable fixing means, such as, for example, a friction fit, an adhesive, ultrasonic welding or the like.

  In one exemplary embodiment, the safety beacon light source LED L1 produces blue light and is at least activated when the illuminator head 40 produces illumination light, but the light source 43 of the illuminator head 40 And the second light source L1, L2 may be individually controlled, programmed and / or actuated, for example by a variant of the pressing and opening actuator 22. The internal light source LED L2 produces white light and also within a range of 90 degrees or less by a substantial angle, as shown in FIG. 6C, in a direction away from the lighting device head 40, preferably from the clip 50. It may operate when turning.

  Preferably, pivoting of the illuminator head 40 may activate and / or deactivate the light generating elements L1 and / or L2 at a predetermined pivot angle. The predetermined angles, which need not be particularly accurate, are responsive to the strength of the magnet 40M, the relative position of the magnet 40M and the Hall effect detector HS, and the sensitivity of the detector HS. The strength of magnet 40M, the relative position of magnet 40M and Hall effect detector HS, and the sensitivity of detector HS each obtain such activation and / or deactivation at a specific or desired angle. It can be adjusted when. A predetermined angle of pivoting between about 60 degrees and about 90 degrees is currently considered desirable.

  When the illuminator head 40 is so arranged, the magnet 40M in the illuminator head 40 faces the Hall effect sensor HS on the circuit board 200 in the housing 30 (ie, sufficiently close to it). ), Whereby, for example, the magnetic field of the magnet 40M, as indicated by the field line MFL, is to act on the Hall effect sensor HS. When the Hall effect sensor HS detects that such a magnetic field exceeds a predetermined threshold, the Hall effect sensor HS energizes the controller L on the circuit board 200 to the white light source LED L2, and the blue light source LED L1 It responds to turn off the power supply. When the lighting device head 40 pivots away from its rotational position, the intensity of the magnetic field in the Hall effect sensor HS is reduced until it falls below the detection threshold of the Hall effect sensor HS, on which the controller emits white light De-energize the LED L2, and energize the blue light source LED L1.

  The foregoing features are rotated 90 degrees counterclockwise such that the longitudinal axis 16 is vertical, with the illuminator head 40 at the top end of the illuminator 10 and the tail cap 24 at the bottom of the illuminator 10 It can be better understood by looking at FIG. 6C, which is intended to be at the end. A person using the luminaire 10 in this position either grips the housing 30 by hand or uses the clip 50 to attach the luminaire 10 to himself. For example, the lighting device 10 is attached to the person's clothes or other wearables or equipment. In this orientation, the light generated by the illuminator head 40 is directed forward. For example, they are directed to the person's work area or to the front where the person may move. In addition, the white radial beam produced by the LED L2 and exiting through the lens 26 is directed directly downwards, thereby illuminating the path directly ahead of the person, thereby over the obstacle. It is less likely to pass through or slip into a hole.

  Thus, the lighting device 10 plays a role in at least two different purposes and conditions, for example as a light mounted on a helmet and a safety light, and secondly on the body or hand Includes features that allow it to serve as a flashlight. Furthermore, changing the lighting device 10 from one purpose to the other is by the fact that the lighting device 10 can be easily mounted and removed by engaging and disengaging the clip 50 to the mounting bracket 60 Promoted. Additional convenience is provided as the mounting bracket 60 can remain attached to a helmet or other object while the lighting device 10 is removed and used for another purpose.

  7A and 7B are perspective views showing an exemplary embodiment of the clamp bracket 60 attached to the exemplary clip 50 of the exemplary lighting device 10 of FIGS. 1A-1D, respectively. 7C and 7D are enlarged views of an exemplary embodiment of clamp bracket 60. FIG. 7E and 7F are perspective views of clamp bracket 60 attached to clip 50. FIG. 7G is a plan view of an exemplary clamp bracket 60. FIG. If the mounting bracket 60 or other attachment is permanently attached to the lighting device, the use of such lighting device may be limited.

  The illumination device 10 avoids such limitations by being configured to receive a plurality of different accessories that are attachable to and removable from the illumination device 10, for example from the elongated clip 50 of the illumination device 10. The reason for this is that the various different attachment parts make use of a common mounting arrangement and are thereby mutually interchangeable and interchangeable. One example of the manner in which such accessories, as well as their accessories and other accessories, can be attached to and removed from the elongated clip 50 of the lighting device 10 will now be described. Meanwhile, other examples are described below.

  One example of such an attachment is a mounting bracket 60 that can be easily attached to the clip 50 and easily removed from the clip 50. The clip 50 is rotatable about the housing 30 and the longitudinal axis 16, at least to a limited extent, and preferably includes an elongated clip arm 52 extending substantially parallel to the outer surface of the lighting device housing 30. . The elongated clip arm 52 has a relatively narrow portion 52N at its distal end and a relatively wide portion 52B at its central region. The distal end 52N of the clip arm 50 is configured to bend towards the housing 30, thereby providing a more secure clip action, eg, on a belt or pocket, again, There may optionally be openings therein to which lanyards, rubber rings, clips, or other accessories may be attached.

  The mounting bracket 60 includes a C-shaped clamp member 62. This clamping member 62 can be inserted into the object to which the mounting bracket 60 is to be attached, for example the edge of a firefighter's helmet, a hard hat or other headgear, tool container or other work accessory . Such an edge may be clamped within the clamp member 62 by clamping the clamping means 63, for example, one or more pairs of screws 63, and clamping the edge between the clamping anvil 62A and the clamping means 63. Will be held by The mounting bracket 60 defines a base 64 at the end of the clamp member 62 distal from the clamp securing means 63 and also includes a pair of spaced apart bracket arms 66 extending upwardly from the base 64. The bracket arms 66 define an opening therebetween, and the opposite inner side of each bracket arm 66 has a groove 67 therein in the longitudinal direction, for example, in a direction substantially parallel to the base 64. doing.

  The opposite groove 67 is sized and spaced so that the relatively wide portion 52B of the clip arm 52 of the clip 50 is retained internally, and the opposite inner surface of the bracket arm 66 is relatively wide of the clip arm 52. Are separated by a distance which is smaller than the width of the portion 52B but larger than the width of the relatively thin portion 52N of the clip arm 52, such that the thin portion 52N passes between them. As a result, the bracket 60 can slip on the clip arm 52, be held by the clip arm 52, eg, the relatively wide portion 52B of the clip arm 52, and can be easily removed from the clip arm 52. . Thus, the lighting device 10 can be easily converted from a hand-held or clip-held lighting device to a bracket-held lighting device, and again, the bracket-held lighting It can be easily converted from the device to a hand held or clipped lighting device.

  Friction between the bracket 60 and the clip arm 52 and / or the illuminator housing 30 limits longitudinal movement in many applications and also causes the bracket 60 to be mounted on the clip arm 52, for example, the clip arm 52. While sufficient to hold to the base 64 of the upper bracket 60, the lighting device housing 30 and the bracket 60 may or preferably have complementary features that engage more positively is there. In one example, the face of the bracket arm 66 that abuts the housing 30 can be bent to substantially match the curvature of the housing 30, thereby providing friction between the face of the bracket arm 66 and the housing 30. To increase the

  Additionally, the face of the bracket arm 66 abutting the housing 30 can be curved and can have one or more ridges and / or grooves 65. One or more ridges and / or grooves 65 are of a size and shape complementary to the ridges and / or grooves 32 around the periphery of the housing 30, such that the respective ridges and / or grooves engage Thus, the longitudinal movement of the bracket 60 relative to the luminaire housing 30 is clearly limited. In all of the foregoing alternatives, the resilient properties of the clip 50 tending to bias the narrower end 52N toward the housing 30 and preferably abut the housing 30 further include the bracket 62 as the clip 50. Holding on and maintaining such features engaged if the bracket 60 and the housing 30 have complementary grooves and / or ridges 26, 65 which engage To help.

  The lighting device 10 has a clip 50 which is rotatable about the longitudinal axis 16 and the housing 30, and also has a light device head 40 which is pivotable widely relative to the housing 30, so that the user can , And has two degrees of freedom of movement with respect to directing light generated from the lighting device head 40 when the lighting device 10 is mounted on an object, such as a helmet or person, clothes or equipment, etc. Thus, light can be directed over a wider range of directions as compared to lighting devices that are fixedly mounted or provide only one degree of freedom of movement.

  FIG. 8 is a schematic diagram of an exemplary embodiment of an electronic circuit 300 suitable for use in the exemplary lighting device 10 of FIGS. 1A-1D, referred to below. Electrical circuit 300 receives power at connections M2 (B +) and M3 (B-) provided via physical element 202 and 24S, 210, respectively, where the power source is for example , Is a battery providing a voltage VBATT. The circuit 300 is disposed on the circuit board 200. For example, the LED 43 is preferably disposed in the lighting apparatus head unit 40, and the physical properties of the circuit board 200 and the circuit 300 on the circuit board 200 are as follows. It is electrically connected by the target conductors 204 and 220.

  The operation of the lighting device 10, including light sources such as LEDs 43, L1 and L2, is controlled by the controller 320, U5 or the microprocessor 320, U5. The controller 320, U5 or the microprocessor 320, U5 responds to the signal generated by the switch circuit 350 when the contact S1 of the electrical switch 208 opens and closes. Preferably, processor 320, U5 or controller 320, U5 provides control over all functions of circuit 300. The main light source LED 43 is connected to the connection portions M4 (LED +) and M5 (LED-) of the circuit board 200 by the respective conductors 204 and 220.

  The manner in which processor 320 responds to the signal from switch circuit 350 may be responsive to that timing. For example, depending on the number of times of closing and / or opening of the switch in a given period of time and / or the duration of time that the switch is closed. Such signaling can be employed to generate various operating modes or states. Various operating modes or states are, for example, OFF, consecutive ON and / or temporary ON for each LED or combination of LEDs 43, L1 and L2, and, for example, any of LEDs 43, L1 and L2, Or whitening and / or non-whitening, flash, flashing, strobe, "Hi-Brite" (above normal brightness level), time for the combination of LED 43, L1 and L2 Operating modes or states for the on period and / or other desired modes are included. If using the "high brightness" feature usually results in raising the drain of the battery and shortening the operating time, the "high brightness" feature is For example, it can be implemented as a temporary feature that can be accessed by holding the actuator 22 pressed for a period of time when a higher intensity light output is desired.

  In order to energize the light source LED 43, the processor 320 enables the current regulated DC converter circuit 310 to reduce the voltage VBATT to a voltage VBUCK at which the current flowing in the LED 43 is at a predetermined level. The integrated circuit U1 controls the operation of the DC converter 310. The DC converter 310 is, for example, a pulse width modulated buck converter having an inductor L1 and a capacitor C5 that filter voltage pulses near the VBATT generated at its internal switch output pin SW. Feedback of detection of the current flowing through the LED 43 is provided by the resistor R6. This resistor R6 is directly proportional to the current of the LED 43 and produces a feedback voltage VFB which is coupled to the feedback input VFB of the processor 320 via the resistor R5. The AN input, which affects the whiteness of LED 43, can be applied via resistor R4.

  Various predetermined LED 43 current levels can be selected by applying various control signals to the processor 320, for example, via the connection's DIMMING, to a voltage divider including resistors R4, R5 and a filtering capacitor C7. is there. The signal applied at connection DIMMING (or to another node in the feedback voltage divider) can be employed to dim or not dim the light generated by LED 43 and / or through LED 43 The flowing current can be used to increase above the normal "high intensity" level of the light output.

  Current regulator circuit 330, when enabled and controlled by the signal CHARGE_PUMP_ENABLE, receives the output at voltage VBUCK from DC converter 310 and also determines the current flowing in LED L1, for example, the blue safety light LED. For example, a charge pump type DC converter U4 configured to generate a voltage of about +5 VDC, for example. When enabled and controlled by the CHARGE_PUMP_ENABLE signal, it is usually the case that the battery voltage VBATT is less than the voltage required to energize the LED L1. If the battery voltage is sufficient, the LED L1 is energized by the battery voltage VBATT. The current through the LEDs L1, D3 is controlled by the FET control transistor Q2-1 carrying the signal TAILLIGHT. Resistor R12 provides a voltage feedback signal proportional to the current in LED L1 via resistor R13 and connection I_TAILLIGHT. The current of the LED 1 is controlled by the signal TAILLIGHT applied to the FET control transistor Q2-1.

  For example, the OR circuit provided by a pair of diodes D2, eg Schottky diode D2, operates for LED L1 from the higher of eg battery voltage VBATT and output voltage VOUT of charge pump converter U4, eg about +5 VDC It serves to provide current. Here, the LED L1 is a blue LED that normally requires a higher operating voltage than other LEDs. Normally, the battery voltage is sufficient for the blue LED L1. Voltage VOUT is, for example, about +5 VDC, and transistor Q2-1 is controlled by signal TAILLIGHT from processor 320, U5 in response to current feedback signal I_TAILLIGHT, whereby battery voltage VBATT when the battery is discharged. Is driven to cause LED L1 to operate at a predetermined current level, regardless of whether power is obtained from either VBATT from converter U4 or VOUT.

  Current regulation circuit 340 preferably receives power of voltage VBUCK from DC converter 310, and when it is enabled and controlled by signal DOWNLIGHT, the current flowing in LED L2, for example, a white LED, is at a predetermined level. It is configured to control. Resistor R10 provides a voltage feedback signal proportional to the current in LED L2, D1 via connection I_DOWNLIGHT. The current of the LED L2 is controlled by the FET control transistor Q1. In this exemplary embodiment, although a DC converter is not required, the reason is that the voltage required to operate the relatively low power white LED L2 at the desired predetermined current is, for example, the predetermined current This is because the voltage V BUCK required to operate the higher power white LED 43 at the level is smaller.

  The switch circuit 350 provides the command signal to the processor 320 via the connection MODE_SWITCH. MODE_SWITCH is a relatively low voltage, for example, a GND voltage when the contact S1 is closed, and is a relatively high voltage, for example, a voltage of MODE_SWITCH_PULLUP_ENABLE when the switch contact S1 is open. The contact S1 is opened and closed by pressing and releasing the switch actuator 22 of the lighting device 10.

  The head swing position detection circuit 360 includes a Hall effect sensor HS and a Hall effect detector HS when enabled by the application of the operating voltage at the connection SENSOR_ENABLE. Hall effect sensor HS, Hall effect detector HS, when the illuminator head portion 40 is sufficiently pivoted relative to the illuminator housing 30 to raise the magnetic field strength in the Hall effect detector HS to a predetermined level When a magnetic field of a predetermined strength, such as a magnetic field generated by the magnet 40M in the lighting apparatus head unit 40, is received, an output signal is generated at the connection unit HALL_EFFECT_SENSOR.

  The auxiliary output supply circuit 324 generates operating voltages VDD for the processors 320, U5 and other elements of the circuit 300. When the battery sensor 326 is enabled by the signal SENSOR_ENABLE from the processor 320, U5, which turns on the FET transistor Q2-2, connects the voltage divider of the resistors R1, R2 to display an indication of the battery voltage VBATT to the processor 320 The circuit 300 can be provided in a safe state if the voltage VBATT falls to a predetermined level. However, again, if overdischarged or rechargeable, it can be employed to protect the battery from being overcharged.

  FIGS. 9A-9J include ten exemplary alternative embodiments of the rearward-directed light sources L1, L2 and examples of optical elements of the features of the exemplary safety lighting apparatus.
