Abstract

L'invention concerne une lampe à LED rayonnante à huile, comprenant une lampe à LED et un capot rayonnant. Le capot rayonnant est constitué de matériaux à transfert thermique et muni d'un conteneur rayonnant. Un agent de transfert thermique est disposé dans le conteneur rayonnant. Une broche d'électrode d'un talon de lampe à LED est en contact direct avec l'agent de transfert thermique. La chaleur d'une jonction PN dans le talon de lampe à LED est acheminée directement dans l'agent de transfert thermique par la broche d'électrode. La chaleur de la jonction PN est transférée dans une coque en alliage d'aluminium du conteneur rayonnant par l'agent de transfert thermique avec de bonnes performances de dissipation de chaleur, ce qui accroît l'effet de dissipation de chaleur de la lampe à LED.
