Abstract

L'invention porte sur une lampe de projecteur à DEL, laquelle lampe est constituée par une tête de lampe, un radiateur, un circuit de commande, un panneau de lampe à DEL et une lentille. Le radiateur comprend un capot de rayonnement périphérique, un siège de disposition central, des pièces conduisant la chaleur et une plaque de base. Le fond du capot de rayonnement périphérique est relié à la circonférence de la plaque de base. Le fond du siège de disposition central est relié au cercle interne de la plaque de base. Les pièces conduisant la chaleur sont reliées à la paroi interne du capot de rayonnement périphérique et à la paroi externe du siège de disposition central. Le panneau de lampe à DEL et la lentille sont disposés sur la plaque de base à l'intérieur du siège de disposition central. De plus, la lentille est fixée sur le côté interne de la plaque de base, tandis que la tête de lampe est fixée sur le côté externe de la plaque de base. Le circuit de commande incorporé dans la tête de lampe est électriquement connecté au panneau de lampe à DEL par des trous traversants dans la plaque de base. La lampe de projecteur a un meilleur effet de rayonnement et une durée de vie prolongée.
