Is provided.
The human sensor 81 is configured so as to be present in a portion that enters the inside (on the base 7 side) from the top of the translucent cover 5, and the illuminance sensor 83 is configured in a portion near the top of the translucent cover 5. Yes. For this reason, the illuminance sensor mounting portion 851b is provided so as to extend from the human sensor mounting portion 851a to the top side of the translucent cover 5. That is, the illuminance sensor mounting portion 851b exists at a position farther from the LED substrate 23 than the human sensor mounting portion 851a.

The spacer portion 855 has a function of filling a space between the sensor mounting portion 851 and the LED substrate 23. The spacer portion 855 includes a plate-like portion 855a. The plate-shaped portion 855a extends toward the LED substrate 23 from the bottom of the human sensor mounting portion 851a and the bottom of the illuminance sensor mounting portion 851b. The cross-sectional shape of the plate-like portion 855a is, for example, a “ten” shape. Thereby, the support base 85 can be attached to the LED substrate 23 in a stable state.
One plate portion of the cross-shaped plate-shaped portion 583a extends from the bottom wall of the human sensor mounting portion 851a, and the other plate portion extends to the bottom wall of the human sensor mounting portion 851a and the bottom wall of the illuminance sensor mounting portion 851b.

The cross-shaped plate-shaped portion 855a is provided so that two or more three through holes 851c of the human sensor mounting portion 851a do not overlap with the four regions partitioned by the cross. In other words, the two through holes 851c positioned on one side of the right triangle that sandwich the right side of the right triangle sandwich the one plate portion of the cross so that the two through holes 851c positioned on the other side are The plate-like portion 855a is provided so as to sandwich the other plate portion of the cross. Thereby, it can prevent that the three lead wires 81b contact. The long side plate portion of the plate-like portion 855a is located between the two through holes 851d of the illuminance sensor mounting portion 851b. Thereby, it can prevent that the two lead wires 83b contact.
A groove 851f toward the LED substrate 23 is provided in a portion corresponding to the two through holes 851d in the long side plate portion. The groove 851f is configured by using a pair of protruding portions provided on a surface orthogonal to the thickness direction of the long side plate portion.

  The attachment portion 853 is constituted by a pair of extending pieces 853a extending from the spacer portion 855 to the opposite side of the sensor mounting portion 851. The attachment portion 853 has a locking portion 853b that extends from the surface that is the extending tip of the extended piece 853a and does not face the other extended piece 853a to the side where the other extended piece 853a does not exist. The pair of extending pieces 853a is configured to be elastically deformable in a direction in which both of them extend. Elastic deformation is implemented by providing a groove 853c in which the inner part of the pair of extending pieces 853a is recessed from the end surface opposite to the sensor mounting portion 851 in the spacer portion 855 to the sensor mounting portion 851 side. When the pair of extending pieces 853 a are elastically deformed and the locking portion 853 b passes through the through hole that is the sensor fixing portion 23 a of the LED substrate 23, the locking portion 853 b is engaged with the LED substrate 23. In this state, the support base 85 comes into contact with the LED substrate 23 at the spacer portion 855 and the locking portion 853b.

(3) Power supply circuit unit This will be described mainly with reference to FIGS.
The power supply circuit unit 3 includes a power supply circuit 35 for generating power for the LED element 21 from AC power. The power supply circuit unit 3 includes a plurality of circuit components, a circuit board 31 on which the circuit components are mounted, and a connection portion 33 for connecting to the LED module 2. Note that illustration of circuit components is omitted.

(3-1) Power Supply Circuit This will be described with reference to FIG.
The power supply circuit 35 includes a rectifier circuit unit 351, a smoothing circuit unit 353, a power generation unit 355, and a control unit 357.
The rectifier circuit unit 351 is a circuit that rectifies commercial power, and for example, a diode bridge is used. The smoothing circuit unit 353 is a circuit that smoothes the rectified DC power, and for example, a capacitor is used. The power generation unit 355 generates power for the LED element 21 from the smoothed DC power, and for example, a step-down circuit is used.

  The control unit 357 controls lighting / extinguishing of the LED module 2. That is, the control unit 357 lights the LED module 2 when a predetermined condition is met. The conditions here are the presence of people and the illuminance. Specifically, the control unit 357 instructs the power generation unit 355 to generate power to be output to the LED module 2 when the illuminance sensor 83 detects a predetermined darkness and the human sensor 81 detects a person. When the human sensor 81 no longer detects a person, the power generation unit 355 is instructed to stop generating power. Thereby, power saving can be achieved. As the control unit 357, for example, an IC chip in which a program is previously incorporated is used.

  The control unit 357 controls dimming and brightening while the LED module 2 is lit. That is, the control unit 357 changes the amount of light emitted from the LED module 2 when a predetermined condition is met. The condition here is the temperature around the LED element 21, which is dimmed when the temperature rises, and is brightened (returned to the light before dimming) when the temperature falls during dimming. Note that the amount of light is changed by increasing or decreasing the power supplied to the LED module 2.

The dimming and brightening will be described with reference to FIGS.
The power supply circuit 35 includes a temperature sensor 358. As the temperature sensor 358, for example, a polymer-based PTC thermistor can be used. Here, as shown in FIG. 11, a plurality (three in this case) of detection resistors 360a, 360b, 360c are connected in parallel, and the detection resistors 360a, 360b, 360c connected in parallel are connected. A PTC thermistor (358) is connected in series to at least one detection resistor 360a (this circuit is referred to as a detection circuit 360). The control unit 357 is connected in series to the detection circuit 360 and monitors a change in the voltage of the detection circuit 360. Note that a change in the current of the detection circuit 360 may be monitored.

  That is, as the temperature rises, the resistance value of the PTC thermistor (358) rises and the resistance of the detection circuit 360 also rises. When the control unit 357 detects an increase in the voltage of the detection circuit 360, the control unit 357 instructs the power generation unit 355 to decrease the power value output to the LED module 2. When the LED module 2 is lit with low power, the temperature of the LED element 21 will eventually drop. When the resistance value of the PTC thermistor (358) decreases due to the temperature drop of the LED element 21, the resistance of the detection circuit 360 also decreases. When detecting the voltage drop of the detection circuit 360, the control unit 357 instructs the power generation unit 355 to increase (return) the power value output to the LED module 2.

  In addition, by using a polymer system as the temperature sensor 358, the resistance change can be digitally detected as “0” and “1”, and the change in the temperature of the object can be reliably detected. The detection circuit includes three detection resistors in parallel. However, the detection circuit may have a plurality of parallel numbers, and may be two, or four or more.

  The power supply circuit 35 includes a driving power generation unit 359 that generates driving power for driving the human sensor 81 and the illuminance sensor 83. The drive power generation unit 359 is independent of the power generation unit 355 for the LED module 2 and supplies drive power.

(3-2) Circuit Board This will be described mainly with reference to FIG.
The circuit board 31 has a wiring pattern for connecting a plurality of circuit components so as to constitute the power supply circuit 35. The circuit board 31 has a shape close to a long trapezoid.
The circuit components for the power supply circuit 35 are mounted on the circuit board 31, but the human sensor 81 and the illuminance sensor 83 are mounted on the LED board 23, and signals from the human sensor 81 and the illuminance sensor 83 are the LED board 23. Is sent to the control unit 357 via the circuit board 31.
The temperature sensor 358 has a main body portion and a lead wire (not shown), and the lead wire is connected to the circuit board 31 in a state where the main body portion is in contact with the LED substrate 23.

  The circuit board 31 is arranged in the case body 6 so that the longitudinal direction thereof is parallel to the central axis of the case body 6. The shorter base (the shorter side) of the circuit board 31 is located on the base 7 side. In the circuit board 31, both end portions in the width direction (short direction) of the end portion on the base 7 side are inserted into a pair of grooves which are an example of the unit support portion 61 p of the case body 6. Thereby, the movement of the circuit board 31 in the thickness direction of the board is restricted.

  The connection portion 33 is provided at the end of the circuit board 31 on the LED module 2 side, and is electrically connected to the wiring pattern of the circuit board 31. The metal pin 33a extends from the connection portion 33 so that the tip side extends through the LED module 2 and extends toward the translucent cover 5. There are six metal pins 33a, which are provided at intervals.

(4) Envelope The envelope 4 is provided with a cylindrical case body 6 and a translucent light provided at one end of the case body 6 in the central axis direction (the side from which light is emitted from the LED element 21). The cover 5 and the base 7 provided at the other end in the central axis direction of the case body 6 are configured.

(4-1) Translucent cover It demonstrates mainly using FIG.2, FIG3 and FIG.12.
The translucent cover 5 covers the LED module 2 and transmits the light emitted from the LED module 2 to be emitted. The translucent cover 5 has a main body portion 5c having a shape (for example, a hemispherical shell shape) obtained by cutting a hollow sphere with a flat surface, for example.
The translucent cover 5 is made of a resin material having translucency, for example. In the translucent cover 5, diffusion particles may be mixed into the resin material as necessary, or diffusion treatment may be performed on the inner peripheral surface or the outer peripheral surface.

  The translucent cover 5 has through holes 5a and 5b for the sensors 81 and 83 in the main body 5c. Here, the two sensors 81 and 83 have dedicated through holes 5a and 5b, respectively, and there are a total of two through holes. The through holes 5 a and 5 b exist at the top opposite to the opening side of the translucent cover 5. The through holes 5a and 5b are circular when the translucent cover 5 is viewed from the top side. The human sensor 81 and the illuminance sensor 83 are partially exposed on the front side through the through holes 5a and 5b.

The translucent cover 5 has a cylindrical portion 5d extending from the opening edge of the through hole 5a to the opening side end portion of the main body portion 5c in the main body portion 5c. In order to widen the sensing area of the sensor 81, the cylindrical part 5d has a truncated cone shape in which the top side of the cylindrical part 5d expands on the top side. The case body 6 side portion of the cylindrical portion 5d abuts on the outer peripheral surface of the sensor 81. Thereby, the penetration | invasion of a water | moisture content etc. can be suppressed from between the sensor 81 and the through-hole 5a.
The through hole 5b is adjacent to the through hole 5a, and a part of the outer peripheral surface side of the cylindrical portion 5d is missing for the through hole 5b. Thereby, the area for providing the through holes 5a and 5b for the sensors 81 and 83 can be reduced, and the light emitted from the LED module 2 can be reduced from being blocked by the through holes 5a and 5b.

The translucent cover 5 has a positioning portion 5f for positioning with respect to the case body 6 at the opening side end of the body portion 5c. The translucent cover 5 has a coupling portion 5g for coupling to the case main body 6 at the opening side end of the main body portion 5c. The translucent cover 5 has a rotation stop 5h at the opening side end of the main body 5c so as not to rotate with respect to the case main body 6.
Here, the positioning portion 5f is constituted by a protruding portion protruding from the opening side end face of the main body portion 5c. The projecting portion is fitted into the opening end portion of the case body 6 on the translucent cover 5 side. The protruding portion has a cylindrical shape (cylindrical shape in accordance with the shape of the case body 6), but may protrude in an arc shape at intervals in the circumferential direction. To be precise, the protruding portion (positioning portion 5f) is partly lacking in the cylindrical circumferential direction because of the rotation stop portion 5h.

The coupling portion 5g is constituted by a convex portion that protrudes radially outward from the outer peripheral surface of the cylindrical portion constituting the positioning portion 5f. The convex portion engages with the coupling portion 61a at the open end of the case body 6 on the translucent cover 5 side. In addition, each convex part functions as an engaging convex part. The convex portions are continuously present in a partial region of the outer periphery, but may be present in the entire outer periphery of the cylindrical portion, or a plurality may be provided at intervals in the circumferential direction.
The rotation stop portion 5h is constituted by a recess provided in a part of the protruding portion constituting the positioning portion 5f. The rotation stopper 61c at the open end of the case body 6 on the side of the translucent cover 5 is fitted into the recess. One dent exists in the positioning portion 5f, but a plurality of dents may exist at intervals in the circumferential direction.

  In the translucent cover 5, the positioning portion 5 f comes into contact with the inner peripheral surface of the end portion on the translucent globe 5 side of the case body 6, and the coupling portion 5 g is the coupling portion on the translucent globe 5 side end portion of the case body 6. In a state of engaging with 61a, it is attached to the case body 6 by using, for example, an adhesive.

(4-2) Case Main Body A description will be given with reference to FIGS. 4 to 7 and FIGS. 13 to 15.
The case body 6 has a cylindrical shape. The case body 6 has a function of releasing heat from the LED module 2. Specifically, the case body 6 includes a resin case 61 made of a resin material and a metal case 63 made of a metal material. The metal case 63 is provided on the inner peripheral side of the resin case 61 and is in close contact with the resin case 61. positioned. That is, the resin case 61 and the metal case 63 are integrated. The integration uses, for example, insert molding, but may be fixed with an adhesive or the like. Note that even when the adhesive is interposed between the resin case and the metal case, the resin case and the metal case are in close contact with each other.

(4-2-1) Resin Case This will be described with reference to FIGS. 14 and 15.
The resin case 61 has a cylindrical shape that becomes thicker as it moves from the base 7 side to the translucent cover 5 side. Specifically, the thickness of the resin case 61 is substantially constant, and the outer peripheral surface of the resin case 61 has a concave arc shape on the central axis side.

3. About assembly A characteristic part in the assembly of the LED lighting device 1 will be described.
The LED lighting device 1 includes an integration process in which the sensor unit 8, the LED module 2, and the power supply circuit unit 3 are integrated into an integrated unit, and an integrated unit set in which the integrated unit is incorporated in the case body 6 with the base material 9. After that, the base connection step for electrically connecting the base unit 7 and the power supply circuit unit 3 installed by mounting the base to the case body 6 and the translucent cover 5 are attached to the case body 6. And a translucent cover mounting step. Note that either the base connection step or the translucent cover mounting step may be performed first.

(1) Integration Process In the integration process, a sensor coupling process for coupling the sensor unit 8 and the LED module 2 and a module coupling process for coupling the power supply circuit unit 3 and the LED module 2 are performed. Either the sensor coupling step or the module coupling step may be performed first.
In the sensor coupling step, the sensor unit 8 is mounted on the LED board 23 of the LED module 2, and then the mounted sensor unit 8 and the LED board 23 are electrically connected. Here, solder is used. Thereby, the sensor unit 8 can be easily combined. In particular, since the spacer portion 855 of the sensor unit 8 is configured by the cross-shaped plate-like portion 855a, the support base 85 can be attached to the LED substrate 23 in a stable state. Furthermore, since the cross-shaped plate-shaped portion 855a is provided so that the three lead wires 81b of the human sensor 81 and the two lead wires 83b of the illuminance sensor 83 do not contact each other, Can be easily performed.
In the module coupling step, the connection part 33 of the circuit board 31 and the power supply side connection part 23c of the LED board 23 are connected to couple them. That is, in the module coupling step, the metal pins 33a provided on the circuit board 31 are connected and fixed with solder in a state where the metal pins 33a are inserted into the power supply side connection portions 23c (through holes) of the LED board 23. Thereby, the circuit board 31 and the LED board 23 can be combined easily and efficiently.
In addition, since there are three or more metal pins 33a, the LED module 2 and the power supply circuit unit 3 can be firmly coupled even if solder is used to connect the metal pins 33a. Here, there are six metal pins 33a, which are actually electrically connected. However, for example, a metal pin intended for mechanical connection (not electrically connected) may be included.

(2) Integrated unit assembly process In the integrated unit assembly process, the power supply circuit unit 3 is inserted through the central through-hole of the base material 9 attached to the case body 6, and the LED substrate 23 is inserted through the base material 9. It is brought into contact with the surface on the optical cover 5 side. Thereby, the locking piece which is an example of the module side support part 61g of the case body 6 is elastically deformed and locked to the surface of the LED substrate 23 opposite to the base material 9. In this way, the integrated unit can be easily incorporated into the case body 6.
At this time, since the base material 9 has the recess 9a on the inner periphery in accordance with the size (width) of the circuit board 31, even if the circuit board 31 has a size that secures an area for mounting circuit components. The circuit board 31 is allowed to pass. Further, the imaginary line segment connecting the two recesses 9a is formed so as not to pass through the center of the annular base material 9 (off from the center), so that the circuit board 31 is placed on the central axis of the case body 6. The distance between the circuit board 31 and the case body 6 is larger than the arrangement, and the passage of circuit components mounted on the circuit board 31 is allowed.

4). At the time of lighting The LED lighting device 1 has a heat release function (heat radiating part) because it generates heat when the LED module 2 is turned on. The heat generated in the LED module 2 (LED element 21) is transmitted from the LED substrate 23 to the base material 9 and to the case main body 6 via the base material 9.
Part of the heat transmitted to the base material 9 is released to the inside of the case body 6 and the temperature inside the case body 6 rises. That is, the heat radiating portion is composed of at least the base material 9. Since the metal case 63 of the case body 6 is in contact (thermal connection) with the base material 9, the temperature of the metal case 63 rises due to the heat transmitted from the base material 9 and is radiated to the inside of the case body 6. . Part of the heat of the case body 6 is conducted to the resin case 61 and radiated from the resin case 61 to the outside. That is, the heat radiating portion is composed of the metal case 63 and the resin case 61 in addition to the base material 9.
When the temperature in the case body 6 rises in this way, the circuit board 31 is affected by the heat. Further, the circuit components constituting the power supply circuit 35 include components that generate excessive heat. For this reason, the circuit board 31 expands under the influence of heat.
At this time, the circuit board 31 is accommodated in the case main body 6 in a state where the end portion on the base 7 side in the longitudinal direction does not come into contact with the resin case 61. For this reason, even if the circuit board 31 expands in the longitudinal direction due to heat, the end in the longitudinal direction of the circuit board 31 does not come into contact with the case body 6. In particular, when the soldering of the metal pin 33a is used for the connection between the LED substrate 23 and the circuit board 31, if the extending direction of the metal pin 33a and the expanding direction of the circuit board 31 coincide with each other, the bonding with the solder is performed. May come off. However, the end in the longitudinal direction (the end on the base 7 side) that coincides with the extending direction of the metal pin 33a on the circuit board 31 is not constrained, so that the bonding between the metal pin 33a and the solder is released due to thermal expansion. There is nothing.
