The substantially circular second hole 2e for light distribution control means provided From it, the frame portion 2c opening surface 1a of the equipment main body 1 is supported and fixed by fixing means such as screws (not shown) from the fitted into the side.

  The support 11 is for supporting the instrument main body 1 on an installation member 12 such as a ceiling, and is composed of two substantially L-shaped leaf springs formed by pressing a stainless steel plate material. The part is positioned on the outer surface of the instrument body 1 so as to face the radial direction and is fixed with screws or the like.

  The support 11 made of this leaf spring is inserted into the installation hole 13 of the installation target member 12 such as the ceiling surface together with the instrument main body 1 while being bent inward from each other. After returning to the above state, the instrument body 1 is pressed against the inner surface of the installation hole 13, and the instrument body 1 is fixed to the installation member 12 by the pressure contact force. In the case of removal, the reverse operation is performed.

  As shown in FIG. 1, the emergency light 100 is, for example, a small-sized illumination that is driven by an AC 100V having a diameter 2 of the frame member 2 of about 90 to 100 mm, a diameter D2 of the instrument body 1 of about 85 mm, and a power consumption of 13 W. It may be configured as a device. At this time, as described above, the instrument body 1 has a small diameter dimension D2 of the instrument body 1 of only about 85 mm and a height h from the surface 12a of the installation member to the end of the instrument body 1 of about 65 mm. Therefore, the installation hole 13 is small, and the construction becomes easy.

  The battery 5 is housed in a battery case 5a, and is positioned above a light source unit 200, which will be described later, in a cylindrical case of the instrument body 1 so that the battery support member 2d is provided on the inner side of the instrument body 1 of the frame member 2. It is supported and disposed. In the battery case 5a, a plurality of batteries 5 may be provided as an assembled battery as shown in FIG. 1, or a plurality of batteries may be stacked and covered with an outer shell. Good. The battery case 5a may be made of a metal such as stainless steel or aluminum, or may be made of a nonflammable synthetic resin.

  From the viewpoint of reducing the size of the emergency light 100, the battery 5 is provided along the periphery of the instrument body 1, and the battery case 5a is disposed in a direction orthogonal to the axis connecting the positive electrode and the negative electrode of the battery 5 so as to include the battery case 5a. The cross section is preferably formed in a substantially U shape. Thus, by arranging the battery 5 in a space other than the light source unit 200 and the lighting unit 6 described later in the appliance main body 1, the emergency light 100 can be reduced in size and the light source 3, the lighting unit 6, and the battery 5 can be reduced. The influence on each component by the heat generated from each can be reduced.

  The battery case 5 a is provided with a current collector (not shown) and a connection terminal (not shown) for electrically connecting the current collector and the lighting unit 6. As shown in FIG. 1A and FIG. 1B, the current collector serves to electrically connect the plurality of batteries 5 when the plurality of batteries 5 are provided in the battery case 5a. Is.

  The battery support member 2d is provided on the inside of the instrument body 1 of the frame member 2, and fixes and supports the battery case 5a inside the instrument body 1 by supporting the bottom of the battery case 5a. The battery support member 2d is formed in an arc shape such that a contact portion with the bottom of the battery case 5a surrounds the first light distribution control means hole 2a.

  Since the battery case 5 a is only supported inside the instrument main body 1 by the battery support member 2 d provided on the frame member 2, the battery case 5 a It moves in the emission direction. Therefore, the battery case 5 a can be taken out of the instrument body 1 simply by removing the frame member 2 from the instrument body 1. Therefore, as shown in FIG. 1, when the cylindrical battery 5 is provided in the battery case 5a, it is desirable that the axis connecting the positive electrode and the negative electrode of the battery 5 is substantially parallel to the light emission direction of the light source 3. . When the battery case 5a is held inside the instrument body 1 only by the battery holding member 2d, when the frame member 2 is removed from the instrument body 1, the battery case 5a is provided inside the instrument body 1 only by the connection terminals. It will be supported by the lighting unit 6 or a lighting unit housing 6d described later. In such a case, the connection terminal, the lighting unit 6 or the lighting unit housing 6d may be damaged due to the weight of the battery 5 and the battery case 5a. Therefore, the outside of the battery case 5a and the inside of the instrument body 1 are connected, It is preferable that a connection member (not shown) for holding the battery case 5a when the battery case 5a is taken out of the instrument body 1 is provided. Since the connecting member is housed in a space inside the instrument body 1 and inside the instrument body 1 and outside the battery case 5a or outside the lighting unit housing 6d, specifically, a linear body such as a wire or a chain. It is desirable that

  When a connecting member is provided, a connecting member holding means for attaching the connecting member, specifically, a hook portion (not shown) for attaching a connecting member such as a wire or a chain is provided inside the appliance main body 1 or the lighting unit housing. It is preferable to be provided outside 6d from the viewpoint of the manufacturing process and construction of the emergency light 100.

When the frame member 2 is removed from the instrument main body 1 by being attached to the hook portion, the connection terminal is caused by the battery case 5a falling from the instrument main body 1 in the light emitting direction of the light source 3 or the battery case 5a falling. Can be prevented from being damaged.

  The lighting unit 6 for lighting the light source 3 by the battery 5 is housed in a lighting unit housing 6d provided inside the instrument body 1 and placed on the substrate 8 on which the light source 3 is mounted. The substrate 8 is supported by the support member 6c and disposed and accommodated in the lighting unit housing 6d. Inside the lighting unit housing 6d, a charging control means 6a for charging the battery 5 by the external power source 16 shown in FIG. 5 and a lighting control means 6b for lighting the light source 3 using the battery 5 as a power source are mounted on the substrate 8 on the light source 3. It is mounted on the back side surface 8b which is the back side of the mounting surface 8a.

  A heat radiating member (not shown) is provided on the back side surface 8b of the substrate 8 so as to release heat generated from the lighting unit 6 or the light source 3 to the outside of the lighting unit housing 6d or the instrument body 1. It may be provided in close contact with the inside of the lighting unit housing 6d so as to be able to conduct heat. From the viewpoint of reducing the number of components of the emergency light 100, the support member 6c that supports the substrate 8 is made of a material having excellent heat conduction, such as metal, inside the lighting unit housing 6d. You may add the function as a heat radiating member which radiates the heat | fever generate | occur | produced from 3 grade | etc., By heat conduction and a thermal convection.

  Further, when the substrate 8 is supported by the support member 6c, if the support member 6c is sufficiently separated from the wiring pattern on the substrate 8, for example, the support member 6c and the lighting unit housing 6d or It is not particularly necessary to consider the insulation distance from the appliance main body 1, and it is particularly suitable when the lighting unit housing 6d or the appliance main body 1 is made of metal. In this case, it is preferable that the support member 6c is made of an insulating material, for example, a resin material, rubber, or the like in consideration of the insulating properties, and a structure that improves heat dissipation can be realized without causing electrical problems. Is possible. When an insulating material is used for the support member 6c, the support member 6c causes heat generated from the lighting unit 6 or the light source 3 or the like to be external to the lighting unit housing 6d or the instrument body 1 by heat convection and heat conduction. It can have a function as a heat radiating member for radiating heat.

  Further, the support member 6 c has a function for maintaining the desired light distribution control defined for the instrument main body 1 and the frame member 2 of the light source unit 200. When the support member 6c is not used, the substrate 8 is supported only by the glass lens 14 with respect to the lighting unit housing 6d. Therefore, the light source unit 200 is moved to the position relative to the instrument body 1 by removing the frame member 2 or the like. There is a possibility that a deviation occurs, and desired light distribution control for the instrument body 1 and the frame member 2 of the light source unit 200 cannot be obtained. Since the support member 6c supports the substrate 8 in the lighting unit housing 6d, the substrate 8 is not supported only by the glass lens 14, and the fixture body 1 and the frame of the light source unit 200 can be removed even when the frame member 2 is removed. Desired light distribution control for the member 2 can be maintained.

  An inspection switch 10 is mounted on the back side surface 8b. The inspection switch 10 is used when the emergency light 100 is inspected according to laws and regulations. For example, when the inspection switch 10 is operated, the power charged in the battery 5 is supplied. It is for supplying to the light source 3 and confirming whether the light source 3 lights normally. The inspection switch 10 is provided with a pull string 10a as an operation unit.

In addition, when the light source 3 is connected to the lighting control unit 6f or the lighting unit 6 and can be turned on by the power supplied from the battery 5, the notification unit 7 is turned on. Informing means 7 for informing the state of the battery 5 and the light source 3 may be provided corresponding to the battery 5 and the light source 3, respectively. In addition, when only one notification means 7 is provided in the light source unit 200 or the like, the battery 5 is charged, the battery 5 is maintained at substantially full charge, and the light source 3 is connected to the lighting control unit 6f or the lighting unit 6. Lights when connected and in a state that can be lit by power supplied from the battery 5.

  Moreover, you may alert | report the alerting | reporting means 7 by displaying that it is in an inspection operation in a lighting state. For example, when a signal for starting an inspection is input to the inspection circuit 6h by the inspection switch 10, the notification unit 7 notifies that the lighting unit 6 is performing the inspection operation according to the lighting state. In this case, the notification means 7 may be turned on, or the inspection operation may be notified outside the emergency light 100 by a blinking state.

  Note that the notification means 7 may be configured to notify not only the inspection operation but also the inspection result. At this time, it is preferable from the viewpoint of visibility that the lighting state of the notification means 7 differs depending on whether there is an abnormality in the inspection result of the battery 5 and whether there is an abnormality in the inspection result of the light source 3.

As the notification means 7, the notification means 7 that notifies that the inspection operation is being performed is displayed in a lighting state, and the battery 5 is connected to the battery 5 by the charge control means 6 a of the lighting unit 6 using the power supplied from the external power source 16. The charging means 7 is turned on when the battery 5 is substantially fully charged, and the light source 3 is connected to the lighting control unit 6f or the lighting unit 6 and is lit by the power supplied from the battery 5. Informing means 7 that is turned on when the battery 5 and the light source 3 are provided is provided for the notifying means 7 for notifying the charging state of the battery 5 and the notifying means 7 for notifying the connection state of the light source 3, respectively. Each may be notified.
The effect of the present embodiment will be described.

  By placing the charging control means 6a and the lighting control means 6b on the substrate 8 on which the semiconductor light emitting element of the light source 3 is mounted, the lead wire between the light source 3 and the lighting unit 6 can be made unnecessary. Further, since there is no lead wire between the light source 3 and the lighting unit 6, non-lighting of the light source 3 due to deterioration of the lead wire or the like can be reduced. Furthermore, since there is no lead wire between the light source 3 and the lighting unit 6, it is possible to prevent the light source 3 from being unlit due to a defective lead wire between the light source 3 and the lighting unit 6 during assembly or construction in the manufacture of the emergency light 100.

  The glass lens 14 provided in the light source unit 200 and the like has the positional relationship between the optical axis oo of the light source 3 and the central portion of the first light distribution control unit 4 fixed by the fixing unit. A desired light distribution characteristic for the light source 3 and the notification unit 7 can be obtained without causing a deviation in the positional relationship between the light distribution control unit 4 or the positional relationship between the notification unit 7 and the second light distribution control unit 9. .

  Since the battery 5 and the battery case 5a are only supported by the battery support member 2d provided on the frame member 2 inside the instrument main body 1, the battery 5 and the battery case 5a are removed by removing the frame member 2 from the instrument main body 1. The battery case 5a can be taken out of the instrument body 1.

  When the support member 6c that supports the substrate 8 is made of a material having excellent heat conduction such as metal, for example, heat generated from the lighting unit 6 or the light source 3 can be dissipated by heat conduction and heat convection.

  Further, if the support member 6c is sufficiently separated from the wiring pattern on the substrate 8, for example, it is not necessary to consider the insulation distance between the support member 6c and the lighting unit housing 6d or the instrument body 1, It is possible to realize a configuration with improved heat dissipation without causing electrical problems.

  Further, since the support member 6c supports the substrate 8 in the lighting unit housing 6d, the substrate 8 is not supported only by the glass lens 14, and the fixture main body of the light source unit 200 can be used even when the frame member 2 is removed. Desired light distribution control for 1 and the frame member 2 can be maintained.

  The first light distribution control means 4 provided in the light source unit 200 is such that the distance from the mounting surface 8a of the substrate 8 to the end of the light distribution direction of the light source 3 of the first light distribution control means 4 is the second light distribution. Since the distance from the mounting surface 8a of the control means 9 to the end of the light emission direction of the notification means 7 of the second light distribution control means 9 is larger than the distance, the light emitted from the first light distribution control means 4 is notified. Or the 2nd light distribution control means 9 does not obstruct | occlude.

  The first light distribution control means 4 provided in the light source section 300 and the light source section 400 is a light source of the first light distribution control means 4 from the end of the recess in the light emission direction of the light source 3 of the first light distribution control means 4. The distance from the light source 3 of the second light distribution control means 9 to the light emitting direction of the light source 3 of the second light distribution control means 9 is from the end of the recess to the light emission direction of the notification means 7 of the second light distribution control means 9. Since it is larger than the distance to the end with respect to the direction, the notification means 7 or the second light distribution control means 9 does not block the light emitted from the first light distribution control means 4.
