Abstract

PURPOSE: To form a comfortable, vital visual environment as the whole interior of a room by shading irradiated radiation light to a CRT screen, converging part of light on the inside of a luminaire, and irradiating the converged light by passing through a light guide to a ceiling in the periphery of the luminaire. CONSTITUTION: Luminous intensity distribution of a luminaire projecting in the direction of 0-60 degrees is obtained by shading light having a vertical angle of 60-90 degrees from a fluorescent lamp 1 with a louver 2. Direct light from the fluorescent lamp 1 and part of light reflected by a reflecting plate 3 are converged on the light receiving surface 5 of a light guide 4. Light received on the light receiving surface 5 is irradiated to a ceiling surface 7 from the luminescent surface 6 of the light guide 4. The reflection of high-intensity luminescent surface of the luminaire to a CRT screen is suppressed, the ceiling surface is brightly illuminated, and a bright, vital visual environment can be obtained in the whole interior of a room.
