More Information
Summary: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 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 fluorescent lens 4 and the light-emitting body 3. The light-emitting device 1 secures heat dissipation performance, while increasing the light emission area.
