  Further, since the lid can be held in the closed state by the movement latching member 11 and the fixed latching member 12, even if the latching mechanism 25 forgets the engagement operation between the lid and the lamp body, The body and the lamp body are held in a closed state by the engagement of the movable locking member 11 and the fixed locking member 12 by the opening / closing device 10 (24), and the lid body is not opened carelessly by vibration or wind. .

  Further, the constituent means (stopper) for holding the lid body in the opened state and the constituent means for holding the lid body in the closed state are one common constituent means comprising the movable locking member 11 and the fixed locking member 12. Therefore, it is not necessary to perform the respective functions with separate configuration means, the configuration is simple, the assembling work can be easily performed, and a cost-effective lighting apparatus can be provided.

  Each component constituting the holding mechanism of the switchgear is a simple and simple configuration that can be formed by pressing a metal bar or metal plate, and the main component is the movement locking member 11. The fixing and locking member 12 and the release mechanism 14 have a small number of parts, and the lamp body has a support boss e (28) and the like, and the holding mechanism of the switchgear can be formed by simple processing. It is possible to provide a luminaire that can be attached, has a simpler structure, can be easily assembled, and is cost-effective.

  Since the holding mechanism of the switchgear is provided on the pole P side of the lamp body 22, it can be arranged apart from the latch mechanism attached on the side far from the pole P. As in Patent Document 1, the latch device and the fall prevention device are arranged. In addition, the holding mechanism of the switchgear according to the present invention is not integrated and configured, the structure is simplified, and the work of assembling using narrow and complicated parts in a narrow part is also unnecessary.

  Further, the operation of the latch mechanism and the opening / closing operation of the lid can be performed at a position apart from the pole P, and the operation at a higher place can be further facilitated without the pole interfering with the operation. Can do.

 Further, since the lighting fixture is provided in the vicinity of the hinge c (27) on the hinge c (27) side, the movable locking member 11 to be connected to the lid has a short configuration, and is a small opening and closing that does not take up space. An apparatus is comprised and it can install using the narrow dead space of the support part 22d of the pole P, and can prevent the enlargement of the whole lighting fixture.

  Since the holding mechanism of the switchgear is provided in the vicinity of the hinge, if the equipment of the holding mechanism of the switchgear is caught inside and the release mechanism 14 is operated, the engaged state cannot be released In this embodiment, since the holding mechanism of the opening / closing device is provided on the hinge side of the lamp body and the lid, a gap is formed between the lamp body and the lid, and a tool such as a screwdriver is inserted through the gap. It is also possible to repair by removing the hooked state of the parts.

  The preferred embodiment of the present invention has been described above, but the present invention is not limited to the above-described embodiment, and various design changes can be made without departing from the scope of the present invention.
