Abstract 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. La présente invention concerne un dispositif électroluminescent résistant à la chaleur. La luminance est accrue par l'augmentation de la surface d'émission 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 l'élément 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 l'élément de dissipation thermique (2); et une couche d'isolation 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 d'émission lumineuse.
