Spread illuminating apparatus with light reflection-diffusion layer on optical path conversion means
Patent number: 6712492Abstract: The present invention provides a spread illuminating apparatus which can ensure uniform brightness over its entire screen. A light reflection-diffusion layer is formed on a light conductive member at a face provided with an optical path conversion means. Light emitted from spot-like light sources is reflected efficiently by the light reflection-diffusion layer toward a transparent substrate, and light intensity degrades in a substantially linear manner with the increase in distance from respective spot-like light sources. Sharp change of brightness on an observation surface can be prevented due to the light intensity degrading linearly.Type: GrantFiled: March 22, 2002Date of Patent: March 30, 2004Assignee: Minebea Co., Ltd.Inventors: Takahiro Shimura, Yoshiki Nakamura, Koichi Toyoda -
