Abstract

Une lampe à LED comprend un dissipateur thermique (3), une plaque de lampe (3) et un support de fixation de tête de lampe (6). La plaque de lampe (2) est directement fixée sur le dissipateur thermique (3); le dissipateur thermique (3) est doté d'une surface de dissipation de chaleur conçue autour de sa surface périphérique, d'une cavité de réception (34) à l'intérieur et d'un élément-support (38) conçu sur une partie d'extrémité. L'élément-support (38) est doté d'une ouverture (35) qui communique avec la cavité de réception (34), et l'ouverture (35), au niveau de la partie d'extrémité du dissipateur thermique, est recouverte par la plaque de lampe (2). Comme la plaque de lampe (2) est directement fixée sur le dissipateur thermique (3), la chaleur provenant de la plaque de lampe (2) s'échappe directement via le dissipateur thermique (3). Par conséquent, le problème de dissipation de chaleur est résolu et le coût est réduit.
