A light-emitting diode illumination device comprises a standard light-bulb base for receiving AC electrical power, a power supply assembly securely attached and electrically connected to the standard light-bulb base, a planar disc securely attached to the power supply assembly, and a plurality of high-efficiency light-emitting diode chips securely mounted on the bottom surface of the planar disc and electrically connected to the power supply assembly. The standard light-bulb base has the capability of being screwed into a standard light-bulb socket on a ceiling or a wall of a room. In another embodiment of the invention, the planar disc has the capability of being positioned into a grid of a suspended ceiling or a grid of a wall of a room. The light-emitting diode illumination device may further comprise a screen securely mounted below the plurality of high-efficiency light-emitting diode chips. This invention relates to illumination devices, and the principal use of the invention is for ceiling lamps and wall lamps in a room.
Un dispositif d'éclairage à diode électroluminescente comprend un culot pour ampoule standard permettant de recevoir une alimentation électrique en C.A., un bloc d'alimentation fixé solidement et branché électriquement au culot pour ampoule standard, un disque planaire fixé solidement au bloc d'alimentation, et plusieurs puces à diodes électroluminescentes haute efficacité montées solidement sur la surface inférieure du disque planaire et reliées électriquement au bloc d'alimentation. Le culot pour ampoule standard peut être vissé dans une douille d'ampoule standard sur un plafond ou un mur de salle. Dans un autre mode de réalisation de l'invention, le disque planaire peut être positionné dans une grille de plafond suspendu ou dans une grille de mur de salle. Le dispositif d'éclairage à diode électroluminescente peut également comporter un écran monté solidement en dessous de la pluralité de puces à diodes électroluminescentes haute efficacité, et la principale utilisation de la présente invention concerne les lampes de plafond et les lampes de mur d'une salle.
