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.
La présente invention concerne un dispositif électroluminescent résistant à la chaleur. La luminance est accrue par laugmentation de la surface démission lumineuse. Un dispositif électroluminescent (1) comprend : un élément de dissipation thermique de type plaque (2); un corps électroluminescent (3) émettant une lumière linéaire ou superficielle et qui est monté sur lélément de dissipation thermique (2) et comporte un substrat (31) et un stratifié semi-conducteur (32) formé sur le substrat (31); une lentille fluorescente (4) recouvrant le corps électroluminescent (3) sur lélément de dissipation thermique (2); et une couche disolation thermique sous vide du côté du corps électroluminescent (5) formée entre la lentille fluorescente (4) et le corps électroluminescent (3). Le dispositif électroluminescent (1) garantit une performance de dissipation thermique tout en augmentant la surface démission lumineuse.
