Abstract

L'invention concerne une lampe à LED, comportant une pluralité de LED individuelles montées sur une structure de support commune et reliées électriquement les unes aux autres pour recevoir un courant fourni par une source de courant commune. La structure de support est constituée d'une tôle couplée thermiquement aux LED pour dissiper la chaleur qu'elles produisent et comportant une pluralité d'ailettes, orientées suivant un plan horizontal, portant chacune une LED. L'invention concerne également un procédé de conception de la lampe consistant à déterminer au départ les besoins en éclairage d'une surface à éclairer, et à les convertir en contraintes permettant de réaliser la lampe et d'utiliser des sources de courant optimales.
