Publication number: 20180203297Abstract: A surface light source device includes laser light sources, first light guide elements, and a second light guide element. The laser light sources emit laser beams. The first light guide elements mix a plurality of laser beams emitted from the laser light sources to convert the plurality of laser beams to linear light. The second light guide element receives the linear light and converts the linear light to planar light. The laser light sources are disposed in regions separated by the first light guide elements. The surface light source device dissipates heat released from the laser light sources to the regions.Type: ApplicationFiled: March 16, 2016Publication date: July 19, 2018Applicant: MITSUBISHI ELECTRIC CORPORATIONInventors: Tetsuo FUNAKURA, Tomohiro SASAGAWA, Eiji NIIKURA, Nami OKIMOTO, Saki MAEDA
