Abstract

L'invention concerne un dispositif d'éclairage à DEL. Le dispositif d'éclairage à DEL comprend : un module de DEL ; une base thermique couplée au module de DEL pour absorber la chaleur ; une enceinte thermique comprenant un espace intérieur étanche dans lequel est injecté un fluide de travail ; une unité d'absorption thermique qui est combinée avec la base thermique pour absorber la chaleur et qui comporte, sur sa paroi intérieure, une mèche ; et une unité de rayonnement thermique dans lequel le fluide de travail évaporé dans l'unité d'absorption de chaleur est condensé pour fournir de la chaleur. Le dispositif d'éclairage à DEL résiste à la contamination et permet d'éliminer facilement la contamination, si bien que la dégradation des performances d'évacuation thermique est rendue minimale et que la maintenance devient facile. En outre, le dispositif d'éclairage à DEL rayonne de la chaleur à partir du module de DEL tout en évitant que la chaleur du soleil lui soit transmise, si bien que l'on évite que le dispositif d'éclairage à DEL soit chauffé par la chaleur solaire.
