The internal pressure in the housing 51 can be adjusted.

In addition, although the illuminating device 10 was set as the structure provided with the lighting unit 20 which accommodated the power supply module 21 and the control unit 22 side by side in the globe 11, it is not restricted to this, The control unit 22 is with the lighting unit 20. The structure provided in another body may be sufficient.
FIG. 7 is a diagram illustrating the lighting device 110 in which the control unit 122 is provided separately from the lighting unit 120. The control unit 122 is accommodated in a case 111 provided separately from the lighting unit 120. In addition, in the illuminating device 110 shown in FIG. 7, about the structure same as the illuminating device 10 mentioned above, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  The illuminating device 110 includes a storage battery unit 50, an illuminating unit 120, and a control unit 122, in which cables derived from the end portions of the respective units are externally connected to each other by connectors. Although not shown, the illumination unit 120 accommodates the light source unit and the power supply module 123 in the globe 121 so as to maintain the immersion resistance. In addition, the control unit 122 accommodates a control unit 124 in the case 111 while maintaining immersion resistance. The casing 51 of the storage battery unit 50, the globe 121 of the lighting unit 120, and the case 111 of the control unit 122 are formed to have the same diameter with a circular cross-sectional outer shape. The casing 51 of the storage battery unit 50, the globe 121 of the lighting unit 120, and the case 111 of the control unit 122 have the same outer diameter, but may have different thicknesses.

A cable gland 16 is attached to the end of each unit. In the lighting device 110, a first cable 161 for supplying commercial power to the lighting device 110 extends from the one end portion 122A side of the control unit 122, and the control unit 122 is connected to the lighting unit 120 from the other end 122B side. Two cables 162 are extended. A third cable 163 extends from the one end portion 120A side of the lighting unit 120, and the second cable 162 and the third cable 163 are connected to each other by the connector 40 outside the units 122 and 120. .
Further, a fourth cable 164 that connects the storage battery unit 50 to the illumination unit 120 extends from the other end 120 </ b> B side of the illumination unit 120, and the fourth cable 164 extends from the storage battery unit 50. It is connected to the cable 165 by a connector 40 outside the units 120 and 50.

  An inspection switch 17 is provided at one end 122 </ b> A of the control unit 122. When the commercial power is supplied to the control unit 122 via the first cable 161 connected to the one end 122A side of the control unit 122 by the function of a control unit (not shown) housed in the case 111, The lighting unit 120 is turned on at a normal time by using a commercial power source. In addition, the control unit 122 detects that the supply of commercial power has stopped, controls the storage battery unit 50 and the lighting unit 120, supplies power from the storage battery unit 50 to the lighting unit 120, and supplies the power from the storage battery unit 50. The lighting unit 120 is turned on by the power source. Further, the control unit 122 controls the storage battery unit 50 to always charge the storage battery accommodated in the storage battery unit 50 when commercial power is supplied.
