Abstract

PURPOSE: To reduce the space to be occupied by an illuminating system, while increasing the illuminating efficiency, by obtaining the effects of the light source of two lamps from a light source of one lamp with the use of a simple reflecting plate and by making effective use of the optical flux, which might not otherwise be used as a direct light, in addition to the direct light from the both light sources.
