Abstract

PURPOSE: To eliminate the need of forming a separate inspection opening in the face of the ceiling so as to facilitate the work of inspecting a lighting inverter by having an inspection opening formed in the upper part of the body of a luminaire with the inspection opening for the inverter and having a supporting plate with the fixed inverter removably mounted onto the inspection opening from its underside. CONSTITUTION: The body of a recessed luminaire 1 with an inspection opening 2 for an inverter 4 of such lighting equipment type as to be embedded and mounted in the face of the ceiling has the inspection opening 2 formed in its upper part, with a supporting plate 3 covering the opening 2 arranged in the same upper part. And the plate 3 is adapted to be removably mounted onto the opening 2 from its underside, it has the lighting inverter 4 feeding electricity to plural luminaires fixed to its top face and has a reflecting surface formed by its undersurface. The maintenance and control of the luminaires can be facilitated since the inverter 4 can be demounted without complexity from the body so as to do the work of inspecting the inverter 4 without accordingly having the need of forming a separate inspection opening for the inverter 4 in the face of the ceiling near a position where the luminaire is arranged.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an embedded lighting fixture with an inverter inspection port which does not require a separate inspection port for the inverter on the ceiling surface and can be easily inspected.

[0002]

2. Description of the Related Art Conventionally, when installing a lighting inverter for supplying power to a fluorescent lamp luminaire in an invisible position on the ceiling,
An inspection port for maintenance and inspection of the lighting inverter has to be provided in the vicinity thereof, which not only takes time and labor for the construction work but also increases the construction cost and impairs the appearance of the ceiling surface. There is also a method of removing the main body of the lighting fixture installed on the ceiling surface and using the opening after that as the inspection opening instead of providing the inspection opening, but the opening of the required size cannot be obtained unless it is a fairly large lighting fixture. Not only that, there is a drawback in that it is time-consuming because the main body of the lighting fixture needs to be removed from the ceiling surface and inspected and then attached again.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to improve the drawbacks of the above-mentioned conventional apparatus, and it is not necessary to separately provide an inspection port for the lighting inverter on the ceiling surface near the installation position and to perform inspection work. It is an object of the present invention to provide an embedded lighting fixture with an inverter inspection port that can be easily performed.

[0004]

In order to solve the above-mentioned problems, in the embedded lighting fixture with an inverter inspection port of the present invention, an inspection port is formed in the upper portion of the main body of the illumination device, and the lighting inverter is fixed on the inspection port. The support plate is detachably attached from the lower side of the inspection port.

[0005]

[Operation] When performing maintenance and inspection of the lighting inverter,
By removing the lamp from the socket and then removing the support plate covering the upper inspection port from below, the lighting inverter fixed on the support plate can be taken out, so that the inspection work can be easily performed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embedded lighting fixture with an inverter inspection port according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view thereof, and FIG. 2 is an explanatory view showing a mounting structure of the support plate. The embedded luminaire 1 with an inverter inspection port is a type of luminaire which is embedded and mounted on the ceiling surface. An inspection port 2 is formed in the upper part of the main body, and a support plate 3 is provided to cover the inspection port 2. . The support plate 3 is detachably attached from the lower side of the inspection port 2, the lighting inverter 4 for supplying power to a plurality of lighting fixtures is fixed to the upper surface thereof, and the lower surface thereof is a reflecting surface. .

To attach the support plate 3 to the inspection port 2, as shown in FIG. 2 (a), an engagement hole 3a provided at one end thereof is provided.
Is engaged with the engaging projection 2a provided on the edge of the inspection port 2, and in this state the necessary wiring is connected to the lighting inverter 4, and then the other end is rotated as shown in FIG. Then, it is lifted and fixed to the edge of the inspection port 2 with a screw 2b. The reflection surface of the lower surface of the support plate 3 becomes a part of the reflection plate of the lighting fixture 1.

For maintenance and inspection of the lighting inverter, after removing the lamp 6 from the socket 5, the screw 2b of the support plate 3 covering the inspection port 2 is removed and rotated to the position shown in FIG. Remove the wiring of the inverter 4 for lighting in the state,
The engagement hole 3a is removed from the engagement protrusion 2a, the support plate 3 is removed together with the lighting inverter 4, and maintenance and inspection work is performed. After the inspection work is completed, the support plate 3 is attached to the inspection port 2 and the lamp 6 is connected to the socket 5 again in the same procedure as described above.

The means for attaching the support plate 3 to the inspection port 2 is not limited to the above-mentioned embodiment, and for example, all of them may be screwed, or other well-known fixing means can be adopted. is there.

[0010]

As described above, in the embedded lighting fixture with the inverter inspection port of the present invention, it is not necessary to separately provide the inspection port of the lighting inverter on the ceiling surface near the installation position, and the illumination inverter can be easily removed. Therefore, it is possible to perform the inspection work with ease, and the effect is that the maintenance is easy.
