Further, by forming a communication hole 21a that communicates the light source chamber S2 and the battery chamber S3 in the partition wall 21 that separates the light source chamber S2 and the battery chamber S3, the gas generated from the storage battery 70 is released to the light source chamber S2. Will be able to. That is, it is possible to prevent the gas generated from the storage battery 70 from filling the battery compartment S3. As a result, it becomes possible to suppress an increase in the chamber pressure (gas pressure: atmospheric pressure) of the battery chamber S3 due to the gas generated from the storage battery 70.

Further, in the present embodiment, the outer surface of the case portion 230 on the light source chamber side and the outer surface of the case portion 240 on the battery chamber side are integrated with the case portion 230 on the light source chamber side and the case portion 240 on the battery chamber side. And are almost flush. In the present embodiment, the bottom surface 230a, the side surface 230b, and the top surface 230c of the case portion 230 on the light source chamber side correspond to the outer surface of the case portion 230 on the light source chamber side. Further, the bottom surface 240a, the side surface 240b, and the top surface 240c of the case portion 240 on the battery compartment side correspond to the outer surface of the case portion 240 on the battery compartment side.

By doing so, it is possible to prevent a step from being formed at the connecting portion between the case portion 230 on the light source chamber side and the case portion 240 on the battery chamber side. As a result, the outer shape of the case 20 is suppressed from becoming complicated, and the appearance, ease of cleaning, ease of installation on the ceiling surface (installed portion) 1a, ease of carrying, ease of packing, etc. are improved. You will be able to make it.

Although the preferred embodiment of the present disclosure has been described above, the present embodiment is not limited to the above embodiment, and various modifications are possible.

For example, in the above embodiment, a tunnel light installed on the ceiling surface of the tunnel is illustrated as a lighting device, but the present invention is not limited to this, and the lighting device is embedded in the ground or the like to irradiate garden trees, roadside trees, or the like from below. It is also possible to apply the present disclosure to lighting equipment.

Further, in the above embodiment, an example in which an LED is used as a light source is illustrated, but a semiconductor light source or the like can also be used.

Further, in the above embodiment, the case 20 is formed by integrating the case portion 240 on the battery compartment side, which is composed of parts separate from the case portion 230 on the light source chamber side, into the case portion 230 on the light source chamber side. Illustrate. However, the configuration of the case 20 is not limited to such a configuration. For example, it is possible to form a case 20 divided into a light source chamber S2 and a battery chamber S3 by providing a partition wall portion 21 for partitioning the accommodation space S1 into two spaces on the integrally formed outer wall portion 22. Is.

In addition, the light source, case, and other detailed specifications (shape, size, layout, etc.) can be changed as appropriate.
