20090116245Emission device, surface light source device and display - A light flux control member has a back face provided with a recess and a ring-like-recess-portion surrounding the recess. Output light of a point-like-light-source (light emission element) is incident to the recess and the ring-like-recess-portion. Incident light to the recess is emitted from a light control emission face after inner-propagation. Incident light to the ring-like-recess-portion is refracted as to hardly generate inner-propagation light deflected to directions near to a direction of reference optical axis L, resulting in outgoing from any part of the light control emission face, or, if some outgoing occurs from the light control emission face, such outgoing occurs only at an outer periphery portion of the light control emission face. As a result, illumination light quality is avoided from being reduced by appearance of conspicuous ring-like bright part. In addition, uniform illumination light can be supplied to a broad angle range. Even if a plurality of point-like-light-sources are arranged at intervals, respective light fluxes originated from respective point-like-light-sources are well mixed.05-07-2009

20080204631Surface light source device and display - Overlapping first and second light guide plates have incidence faces located opposite to each other. Each light guide plate has an emission restraint region, an emission gradually-increasing region and an emission promotion region arranged in order from incidence face toward distal end face. In each emission gradually-increasing region, emission light quantity increases gradually away from each emission restraint region toward each emission promotion region. The emission gradually-increasing regions of the light guide plates overlap each other. The emission promotion region of the second light guide plate overlaps with the emission restraint region of the first light guide plate while the emission restraint region of the second light guide plate overlaps the emission promotion region of the first light guide plate. Light from LEDs is limited by windows. Color-mixing of the LED-light occurs in each emission restraint region to become whitened light gaining emission intensity in the emission promotion regions.08-28-2008
