LIGHT-EMITTING DEVICE

摘要

Disclosed is a heat-resistant light-emitting device wherein luminance is increased by increasing the light emission area. A light-emitting device (1) comprises: a plate-like heat dissipation member (2); a light-emitting body (3) emitting linear or surface light, which is mounted on the heat dissipation member (2) and has a substrate (31) and a semiconductor laminate (32) formed on the substrate (31); a fluorescent lens (4) covering the light-emitting body (3) on the heat dissipation member (2); and a light-emitting-body-side vacuum heat insulation layer (5) formed between the fluorescent lens (4) and the light-emitting body (3).  The light-emitting device (1) secures heat dissipation performance, while increasing the light emission area.
