Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a square-shaped lighting fixture arranged on a ceiling surface.

[Conventional technology]

Conventionally, the square-shaped lighting fixtures include those described in Japanese Utility Model Publication No. 54-42555 and Japanese Utility Model Publication No. 63-51009.

The former one is one in which the ceiling plate placed on the upper surface of the central opening is indirectly illuminated through lamps on each side of the square shape through the inner opening. This luminaire can only perform indirect lighting, so it is possible to illuminate directly by arranging a direct luminaire such as a spotlight or chandelier in the center of the luminaire. There is also a problem in that the design of the entire device feels strange.

On the other hand, in the latter, since the lower surface of each side is open and the lamp on each side is used for direct lighting as well as indirect lighting, indirect lighting and direct lighting can be used together, and yet another lighting There is no need to install equipment.

However, in the latter conventional example, since the same lamp is used for both indirect illumination and direct illumination, there is a problem in that it is not possible to use such as performing production illumination by changing the respective illumination conditions.

The present invention has been made in view of the above-described problems, and the purpose thereof is to have direct lighting lamps and indirect lighting lamps individually, so that directing lighting is possible, and the entire fixture is There is no sense of incongruity in terms of design, and it is to provide the optimum lighting equipment for production lighting.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention provides a direct illumination lamp storage portion having closed inner and outer surfaces and an upper surface and an opened lower surface on each side of a square shape. , A lamp for direct lighting is arranged in the lamp housing for direct lighting, and the upper opening of the cavity surrounded by the lamp housing for direct lighting is closed by a reflector, and for each direct lighting facing the cavity. A lamp housing for indirect illumination is provided along the peripheral wall surface of the lamp housing, the space between the upper end of the side wall parallel to the peripheral wall and the lower surface of the reflector is open and the lower surface is closed. A lamp for indirect lighting is stored in the lamp storage part for use.

[Operation] According to the configuration of the present invention, since the direct lighting lamp and the indirect lighting lamp are independent, the direct lighting by the direct lighting lamps arranged in a square shape is used as the base lighting. The indirect lighting can be performed by the indirect lighting lamp which is arranged in the form of being surrounded by the lighting and is independent of the direct lighting lamp. Therefore, the production lighting can be performed by changing the light color of the indirect lighting. It is not necessary to provide another lighting device for such direct lighting, and therefore, the design of the lighting device does not feel uncomfortable, and the effect lighting can be utilized.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings. First
In FIG. 2 and FIG. 2, the instrument body 1 is formed in a square shape, and an opening portion that vertically penetrates is formed in the central portion.

The instrument body 1 is arranged in the opening between the T-bars 5 arranged on the ceiling surface at appropriate intervals, and is fixed above the instrument body 1 between the T-bars 5. The fixture 7 is provided, and the ceiling material 8 is provided above the fixture body 1 by the fixture 7.
Are placed.

The ceiling material 8 is made of rock wool sound absorbing plate, glass wool, metal plate, punching plate, etc. and is removable, so that the upper opening of the instrument body 1 can be used as an inspection port.

It should be noted that equipment such as a speaker, an emergency light, and a sensor can be attached to the corner portion of the instrument body 1.

Each side 1a to 1d of the appliance body 1 closes the ceiling surface and both side surfaces, and an opening 9 is provided on the lower surface to directly form the interior of the lamp housing 2 for illumination. A frame 19 for mounting the looper 10 is arranged in the opening 9 of the direct lighting lamp housing 2, and a ballast 11 is arranged on the ceiling surface of the direct lighting lamp housing 2.
Further, a socket 13 and a reflector 14 are attached to a mounting piece 12 hanging from the ceiling surface, and a lamp 4 for direct illumination is attached to the socket 13.

In this way, the upper opening of the empty space in the central part of the fixture body 1 surrounded by the lamp housing 2 for direct lighting arranged in a square shape is closed by the steel reflecting plate 15, and also in the empty space A. On the peripheral wall surface of each lamp housing portion 2 facing the above, the space between the upper end of the side wall parallel to the peripheral wall surface and the lower surface of the reflection plate 15 is opened in the space A, and the lower surface is closed. A socket 17 for mounting the indirect illumination lamp 3 is attached to the peripheral wall surface facing the indirect illumination lamp housing portion 16.
The reflector 15 is attached to the instrument body 1 with screws 18.

Thus, in this embodiment, the light of the direct lighting lamp 4 is louvered.
Directly illuminate the area directly below via 10 and the light from the indirect lighting lamp 4 is reflected by the reflector plate 15 which is the ceiling surface of the vacant space A.
Indirect illumination is performed by going out below the opening on the lower surface. For example, direct illumination is used as the base illumination, and the effect illumination can be performed by changing the light color of the indirect illumination with respect to the color of the light of the base illumination.

[Advantages of the Invention] The present invention provides direct illumination lamp housings having closed inner and outer surfaces and an upper surface and an opened lower surface on each side of a square shape for direct illumination in the lamp housing for direct illumination. A lamp is provided, and the upper opening of the cavity surrounded by each direct lighting lamp storage section is closed with a reflector, and along the peripheral wall surface of each direct lighting lamp storage section facing the interior, An indirect lighting lamp storage unit was provided in which the space between the upper end of the side wall parallel to the peripheral wall surface and the lower surface of the reflector was open in the void and the lower surface was closed, and the indirect illumination lamp storage unit was stored in this indirect illumination lamp storage unit. Therefore, the direct lighting by the direct lighting lamps arranged in a square shape is used as the base lighting, and the indirect lighting is provided by being surrounded by this base lighting, and the indirect lighting is independent by the direct lighting lamp. Can be done and therefore indirect It is possible to perform directing lighting by changing the light color of the lighting, etc. Moreover, it is not necessary to provide another lighting fixture for direct lighting as in the conventional art, so the design as a lighting fixture does not feel uncomfortable and It has the effect of being able to utilize it.
