Description

[Detailed explanation of the invention] [Industrial application field] This invention is applicable to intelligent buildings, etc.
Regarding lighting equipment that is ideal for CRT work.

[Conventional technology]

Traditionally, CRTs in intelligent buildings, etc.
In many cases, lighting equipment with louvers is installed to illuminate the work area of OA equipment as the optimal lighting device for work.

[Problem that the invention attempts to solve]

However, with the conventional louvered lighting equipment that illuminates the work area of OA equipment, it is easy for people working in the office to work on the CRT.
Problems have been raised that it is difficult to perform other tasks because the room is dark, and that working for long periods of time in a dark environment can make people feel psychologically dark. The reason is that the actual illuminance is the illuminance as a JIS work environment.
Although 500L _x is secured, it seems that the ceiling is dark so it feels dark.

The present invention is intended to solve the above-mentioned problems, and aims to provide a lighting device that secures the necessary brightness of the ceiling surface and the work area of OA equipment, and is optimal for CRT work.

[Means for solving problems]

To this end, the lighting device of the present invention includes a ceiling that is bent into a wave shape to form peaks and valleys.
A lighting fixture with a louver for illuminating the OA equipment work area space is attached to the valley, and an indirect lighting fixture is attached to the peak.

[Effect]

In the present invention, as shown in FIG. 1, for example, a lighting fixture 4 with a louver that illuminates the OA equipment work area space is used to ensure the necessary illumination of the OA equipment work surface, and an indirect lighting fixture 5 is used to illuminate the ceiling surface and the work space. ensure the necessary brightness. In the present invention, indirect lighting is performed by forming wave-shaped folded peaks 2 and troughs 3 on one side of the ceiling and reflecting the light onto the one side of the ceiling, instead of simply providing upper light illumination. This is because when the ceiling surface is flat, there will be uneven brightness on the ceiling surface, and there will be areas with high brightness on the ceiling surface, and this high brightness will be reflected on the CRT screen, causing problems during CRT work. To,
One side of the ceiling is bent into a wave shape to prevent uneven brightness on the ceiling.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view of an office employing an embodiment of the lighting device of the present invention, and FIG. 2 is a plan view thereof. In the diagram, 1 is the ceiling, 2 is the peak, 3 is the valley, and 4 is the
A lighting fixture with a louver illuminates the OA equipment work area, 5 is an indirect lighting fixture, and 6 is an equipment plate.

In Fig. 1, a ceiling 1 in an office is bent into a wave shape to form peaks 2 and troughs 3, and a louvered lighting fixture 4 is attached to the troughs 3 to illuminate the OA equipment work area. Yamabe 2
An indirect lighting (uplight lighting) fixture 5 is attached to. The louvered lighting fixture 4 that illuminates the OA equipment work area is, for example, a well-known fixture that incorporates blades in a grid pattern under the light source and has a shielding angle (limit angle at which the light source can be seen) of 30° to 45°. As shown in FIG. 2, it is attached to an equipment plate 6, and to this equipment plate 6, an air conditioning outlet, a speaker, a fire detector, an emergency lighting, etc. are also attached.

To explain the operation of the present invention having the above configuration, the necessary illumination of the work surface is secured by the lighting fixture 4 with a louver that illuminates the OA equipment work area space,
Indirect lighting (uplight lighting) equipment 5 ensures necessary brightness of the ceiling surface and work space.
In this invention, it is not just a simple top light lighting, but a wave-shaped folded mountain part 2 and a valley part 3 on one side of the ceiling.
indirect lighting is provided by reflecting the light off one side of the ceiling. This is because when the ceiling surface is flat, there will be uneven brightness on the ceiling surface, and there will be areas with high brightness on the ceiling surface, and this high brightness will cause the CRT to
It was reflected on the screen and became a problem when working on a CRT.
To this end, one surface of the ceiling is bent into a wave shape to prevent uneven brightness on the ceiling surface.

[Effect of idea]

As explained below, according to the present invention, indirect lighting fixtures are installed in the peaks, and louvered lighting fixtures are installed in the valleys to illuminate the OA equipment work area space, so that the necessary illumination of the ceiling surface and the OA equipment work area space is provided. It is possible to provide a lighting device that is ideal for CRT work, ensuring brightness, preventing uneven brightness on the ceiling surface, and minimizing reflection of lighting onto the CRT screen.

Furthermore, compared to a case where all the lighting fixtures are equipped with louvers to illuminate the OA equipment work area, the lighting effect is improved and costs can be reduced.
