Abstract

PURPOSE:To obtain the light removed with ultraviolet rays and infrared rays by combining a synthetic resin film and a reflecting plate member to form a hollow lamp body which has a train of angle grooves acting as an optical prism on one face and allows reflection and permeation. CONSTITUTION:A hollow lamp body A is formed into a box shape, and outer plates 1a-1f forming the six faces of the box are made of an opalescent synthetic resin plate. Transparent synthetic resin films 2 with a train of angle grooves are overlapped on one face on the inside of the upper/lower and right/left outer plates 1, 1b; 1c, 1d, and the film 2 is made of polycarbonate. A sheet-shaped reflecting member 3 formed into a sawtooth shape is stuck on the surface of the film 2 overlapped on the upper outer plate 1a so that the reflecting face is gradually expanded toward the longitudinal direction of the lamp body A, reflecting plate members 4 like a mirror plate are stuck on the inner faces of the front and rear outer plates 1e, 1f, an optical fiber cable B is supported through the outer plate 1e located on the sawtooth tip side of the member 3 and the member 4, the light from a device feeding it via the cable B is fed to the lamp body A, and the light from a luminescent surface with no illumination irregularity is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a lighting device, and more particularly to a lighting device having a light source located away from a lighting fixture.

[Conventional technology]

Conventionally, filament type incandescent lamps and discharge type fluorescent lamps have been most widely used as light sources for general lighting.

Using the incandescent lamp or fluorescent lamp as the illumination light source, we use multi-light lighting fixtures (Jumpria), hanging lighting fixtures (pendants), wall-mounted lighting fixtures (brackets), and ceiling-mounted lighting fixtures (shaped lighting fixtures). Lighting equipment such as ceiling lights), recessed lighting equipment, stationary lighting equipment (stands), downlights, and spotlights are in practical use.

[Problem to be solved by the invention]

All of the above-mentioned lighting fixtures have a light source that is either an incandescent lamp or a fluorescent lamp built into the fixture, so lighting fixtures with such light sources have the following problems in actual use. be.

(1) When light sources such as incandescent or fluorescent lamps are used in open spaces, they are dazzling and the range of illumination is narrow.

(2) When a reflector is used in conjunction with the light source, the illumination range becomes wider, but the glare remains the same. Also, the back side of the non-elbow board cannot be illuminated.

Claims (1)

[Claims] A hollow light body is formed by combining a synthetic resin film that has a row of chevron-shaped grooves on one side that acts as an optical prism and is capable of reflection and transmission, and a reflector member, and one end of the optical fiber cable is connected to this light body. and the other end of the optical fiber cable is connected to a light source or a light supply device that removes ultraviolet rays and infrared rays from the light source so that only visible rays can be irradiated.
