Description

[Detailed Description of the Invention] This invention relates to a lighting fixture used for wall illumination of exhibition cases, blackboards, signboards, information boards, displays, etc. in museums, art galleries, etc.

This type of lighting equipment requires uniform wall illuminance.

For this reason, conventionally, as shown in FIGS. 1 and 2, a light shielding/reflecting plate 2 is installed in front of the fluorescent lamp 1, and the light distribution curve Q by the parabolic reflector 3 is adjusted. A curve R was generated.

S is the lamp light distribution curve. The reflector 2 blocks direct light, transforms the reflector 2 into a polyhedron and reflects it onto the reflector shade 3, and then adjusts the light distribution by moving the reflector 2.However, in terms of efficiency, In addition, there is a lot of loss, the center of the wall looks dark to the eye, and the number of lamps that act as a heat source inside the case increases.

Even if the reflective shade 3 is irradiated with an aluminum electrolytic polishing finish, the reflective shade 3 will not work.
It was large in size and had to deal with the shadow of the shade, which also had drawbacks in terms of the number of parts and assembly and installation.

Therefore, the purpose of this invention is to provide a wall lighting fixture that can improve efficiency and ease of assembly.

An embodiment of this invention is shown in FIGS. 3 and 4.

In other words, in this lighting fixture, half of the inner surface of the reflective shade 4 is mirror-finished (indicated by 5) to provide beam reflection characteristics, and the remaining half is baked with white melamine (indicated by 6) to provide diffuse reflection characteristics. This also changes the light distribution curve.

Figure 4 shows an exhibition case using this lighting equipment.

7 is a wall surface, 8 is a floor surface, and 9 is glass.

The diffuse reflection characteristics of this lighting fixture illuminate the wall surface 7 with smooth brightness, and the beam reflection characteristics brightly illuminate the floor surface 8.

Note that the lighting equipment is tilted or has a light shielding plate 11 integrally attached thereto so that the lamp light cannot be directly seen by the person 10 through the glass 9.

In this lighting fixture, the light from the fluorescent lamp 1 is distributed in a slightly directional manner due to the white finish of the reflective shade 4, ensuring smooth illuminance from the top to the bottom of the wall, and the reflected light from the mirror finish is directed towards the bottom of the wall. It can compensate for the lack of illumination, eliminate uneven illumination on the wall, and illuminate the wall only by lighting from above.

The number of lamps can be reduced by giving a material feel to the exhibited products, and there is little impact on the exhibited products.

As described above, the wall lighting device of this invention has a diffuse reflection surface formed on half of the reflective shade to reflect the beam onto the wall surface, and a beam reflection surface formed on the other half to reflect the beam onto the floor surface below the wall surface. The reflected light also illuminates the lower part of the wall surface, thereby uniformly illuminating the wall surface, resulting in high efficiency, simple structure, and improved ease of assembly.Furthermore, the light shielding plate 11 ensures glare prevention. There is.
