Abstract

Cette invention concerne une unité lumineuse d'éclairage grande puissance équipée d'un radiateur intégré, laquelle unité comprend un radiateur (4) et une ou plusieurs DEL grande puissance (1). Les DEL grande puissance (1) sont fixées sur la plate-forme de fixation (3) placée au centre de la face d'extrémité du corps du radiateur (4) et elles sont en contact étroit avec le radiateur (4). A l'autre extrémité correspondant à la plate-forme de fixation (3) du radiateur (4), le radiateur (4) présente un adaptateur (5) de source d'éclairage, lequel est connecté aux anodes et aux cathodes des DEL et peut être connecté de manière amovible à une interface de fixation de la lumière adaptée. A proximité de la position de fixation des DEL (1) fixées sur le corps du radiateur (4), le corps dudit radiateur (4) présente plusieurs trous traversants (2) ménagés le long de l'axe du radiateur (4).
