DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to a lighting fixture that is installed close to a wall or the like and can efficiently illuminate the wall.

〔発明の技術的背景とその問題点〕[Technical background of the invention and its problems]

従来の照温器具には前方ほど拡開するV字形ルーバの背

Conventional heating appliances often include fluorescent lamps, high-pressure discharge lamps, etc. arranged at the back of a V-shaped louver that widens toward the front. This lighting equipment emits bright, yet gentle, non-dazzling light in the forward direction, making it popular as a downlight, for example.

しかしながら、この照明器具は対称配光のため。However, this lighting fixture has symmetrical light distribution.

壁面などに近接して配設した場合5壁面下部だけが明る

合が生じる。
When placed close to a wall, only the lower part of the wall is brightly illuminated, resulting in an inconvenience that the difference in illuminance between the top and bottom of the wall is too large.

However, it is not only uneconomical to provide a separate lighting fixture for wall illumination, but also has the risk of damaging the interior decoration.

〔発明の目的〕[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a lighting fixture that distributes a large amount of light in one direction and emits soft, non-dazzling light.

〔発明の概要〕[Summary of the invention]

本発明はV字形のルーバの対向するルーバ片内面の反射

In the present invention, the reflectance of the opposing inner surfaces of the V-shaped louvers is different, and the lamp is biased toward one side of the louver with a low reflectance, thereby increasing the light distribution in one direction of the louver with a low reflectance. It is something.

Since the inner surface is painted gray (23), the reflected light (R4) is weak.
21), (22) Some light radiates directly downward from the lamp (2) without entering the lamp.

そうして、この照明器具の配光を第2図に示す。Figure 2 shows the light distribution of this lighting fixture.

In the figure, the symbol is the instrument body, and (R) is the light distribution curve. This second
As is clear from the figure, the light distribution curve (R) extends greatly to the right side of the figure, and on the other hand, the overhang to the left side of Figure 1 is extremely small. Therefore, if you install it on the ceiling with the right side of the figure facing the wall, The wall surface can be brightly illuminated all the way to the top. Moreover, since the illumination light is reflected by the louver (2), it feels soft, and glare can be prevented, especially towards the floor.

In the above embodiment, the inner surface of the second louver piece (22) of the louver (2) was painted gray (23), but the present invention is not limited thereto. In short, it is sufficient that the light reflectance is lower than that of the inner surface of the first louver piece (21). Furthermore, there is no strict limit to the angle of the louver pieces; for example, the angles may be asymmetrical or variable, and the point is that they just need to widen toward the front. moreover.

Further, in the present invention, the degree of eccentricity of the lamp with respect to the louver may be the same for all the louvers, or only one set of a louver and a lamp may be provided.

In the lighting fixture of the present invention, the lamp is provided so as to be biased toward the louver piece having a low reflectance at the back of a V-shaped louver in which the opposing louver pieces widen toward the front and the opposing inner surfaces have different reflectances. Therefore, the light distribution to the side where the louver piece with low reflectance is located is increased. For example, when installed on a ceiling close to a wall surface, the wall surface can be brightly illuminated, and there is an advantage that there is less glare.
