  The male screw portion 92 at the other end of the connecting tube 86 is inserted into the connecting hole 56 of the case 43 of the photographing unit 12, and the nut 88 is screwed into the male screw portion 92. The end surface 51 of the case 43 is sandwiched between the case 88 and the case 88 to be fixed.

  Accordingly, the connecting portion 13 can integrally connect the apparatus main body 15 and the case 40 of the photographing unit 12 and can also route the cable A connecting the camera power supply portion 18 and the camera 41 through the communication hole 89 of the connecting tube 86. And Further, the connecting portion 13 is disposed at a position closer to the back side than the front side of the lighting fixture 11 and the front side of the photographing unit 12.

  Next, the operation of the lighting device 10 configured as described above will be described.

  In order to install the lighting device 10, with the lighting unit 16 removed, the fixture main body 15 is installed on the installation portion, and a power line drawn from the installation portion is connected to the terminal block 19. After that, the lighting unit 16 is attached to the fixture body 15.

  Then, when power is turned on to the lighting device 10, AC power is supplied to the lighting power supply unit 17 and the camera power supply unit 18. The lighting power supply unit 17 converts an AC power supply into a lighting power supply and supplies it to the lighting unit 16, and the lighting unit 16 lights up and illuminates. At the same time, the AC power supply is converted into operating power by the camera power supply unit 18 and supplied to the camera 41, and the camera 41 is activated.

  When the camera 41 is activated, shooting by the image sensor is started, and the shot video is stored in the storage unit.

  When the camera 41 captures an image, light from the lighting apparatus 11 may be reflected on the front side of the camera 41 and enter through the lens unit 82, but around the lens unit 82 of the camera 41, At least on the front side of the front cover 46, which is the side, a light reflection reducing unit 72 for reducing the reflection of light from the lighting fixture 11 is provided, so that light reflected on the front side of the camera 41 enters the lens unit 82. Is reduced, and good photographing becomes possible.

  Further, when the camera 41 takes a picture, the light emitting section 83 emits an indicator light to indicate that the camera is in a photographing state. Since the indicator light includes insect attracting light having an insect attracting property to attract insects, for example, insects to be attached to the lens unit 82 of the camera 41 are attracted to the light emitting unit 83, and the insects are extracted from the lens unit 82. Keep away from them so that they do not affect shooting.

  Further, the camera 41 generates heat with the photographing operation, but the heat generated by the camera 41 is transmitted to the case 40 and is radiated from the surface of the case 40 to the outside air. Further, a part of the heat transmitted from the case 40 is transmitted to the fixture main body 15 of the lighting fixture 11 through the connecting portion 13 and is radiated. Therefore, the temperature rise of the camera 41 is suppressed, and the temperature of the camera 41 is maintained within the rated temperature.

  In addition, by wirelessly connecting the communication terminal to the camera 41 and operating the communication terminal, the video stored in the storage unit of the camera 41 is confirmed by the communication terminal, and the video data is acquired by the communication terminal.

  When the power supply to the lighting device 10 is cut off, the lighting unit 16 is turned off and the camera 41 stops operating.

  In addition, since the life of the camera 41 is shorter than the life of the light emitting module 29 (semiconductor light emitting element) of the lighting unit 16, the camera 41 is replaced. To replace the camera 41, remove the decorative screw 45 fixing the cover 44 to the case 43, remove the cover 44 from the case 43, remove the camera 41 integrally with the cover 44, and remove the cable from the camera 41. Remove A. Subsequently, the cable A is connected to the camera 41 to be replaced, the cover 44 integrated with the camera 41 to be replaced is arranged in the case 43, and the cover screw 44 is attached to the case 43 by tightening the decorative screw 45.

  In the lighting device 10 of the present embodiment, the lighting unit 11 and the case 40 of the imaging unit 12 are mechanically connected by the connection unit 13, and the electrical connection between the lighting unit 11 and the case 40 of the imaging unit 12 is performed. In order to enable wiring, the camera 41 can be provided with a simple configuration.

  Since the connecting portion 13 uses the connecting tube 86, mechanical connection and electrical wiring between the lighting fixture 11 and the case 40 of the imaging unit 12 can be easily realized.

  Since the connecting portion 13 is disposed at a position closer to the back side than the front side of the lighting fixture 11 and the front side of the photographing unit 12, the connecting portion 13 is visible from the front side of the lighting fixture 11 and the photographing unit 12. And the appearance can be improved.

  Further, a photographing unit 12 is connected to a side portion of the lighting apparatus 11 by a connecting portion 13, and the photographing unit 12 is supported by the lighting apparatus 11 in a cantilever state. Although there is a possibility that the camera 41 disposed in the case 40 of the photographing unit 12 is disposed at a position closer to the lighting fixture 11 side, the moment applied to the connecting portion 13 by the own weight of the photographing unit 12 is reduced. In addition, it is possible to reduce the droop of the photographing unit 12, and to keep the camera 41 at a predetermined position with respect to the lighting apparatus 11. This allows the camera 41 to shoot a predetermined shooting range without shifting the shooting direction of the camera 41.

  By arranging the camera 41 arranged in the case 40 of the photographing unit 12 at a position closer to the lighting fixture 11, a space between the camera 41 and the case 40 on the side opposite to the lighting fixture 11 is wide, and a large space is provided. As a result, the terminal portion 84 is provided on the end face of the camera 41 so as to face the space, and the cable A can be connected to the terminal portion 84 of the camera 41 using the space.

  Since the imaging unit 12 is connected to one end of the lighting fixture 11 in the longitudinal direction, a sense of unity with the lighting fixture 11 is obtained, and the appearance can be improved.

  Further, around the lens portion 82 of the camera 41, at least on the front side of the front cover 46, which is the front side of the camera 41, the light reflection reducing portion 72 for reducing the reflection of light from the lighting fixture 11 is provided. In addition, light reflected on the front side of the camera 41 can be reduced from being incident on the lens unit 82, and good photographing can be performed.

  Also, at the time of shooting with the camera 41, the light emitting unit 83 emits indicator light to indicate that the camera is in the shooting state, but since this indicator light includes insect attracting light having an insect attracting property to attract insects, For example, insects that are likely to adhere to the lens unit 82 of the camera 41 are attracted to the light emitting unit 83, and the insects are moved away from the lens unit 82, so that the effect of insects on photographing can be suppressed.

  Further, the camera 41 generates heat during shooting, but the heat generated by the camera 41 is transmitted to the metal case 40 and is radiated from the case 40, so that the heat radiation of the camera 41 can be secured and the temperature of the camera 41 can be maintained. The rise can be suppressed.

  Since the lighting device 11 and the case 40 of the photographing unit 12 are connected by the metal connecting portion 13, the heat generated by the camera 41 is transmitted from the case 40 to the lighting device 11 (the device main body 15) through the connecting portion 13. Heat dissipation can be improved.

  Note that the electric device is not limited to the camera 41, and may be another electric device such as an illuminance sensor, a human sensor, or an emergency light source having a storage battery.

  Although several embodiments of the present invention have been described, these embodiments are provided by way of example and are not intended to limit the scope of the invention.
