Abstract

L'invention concerne une lampe d'automobile combinée à laser et DEL, se rapportant au champ technique des lampes d'automobile et comprenant une structure de coque de lampe, un module de dissipation thermique, un module de source de lumière à DEL et un module laser, le module de source de lumière à DEL et le module laser étant agencés dans la structure de coque de lampe. Le module de dissipation thermique est connecté respectivement au module de source de lumière à DEL et au module laser afin d'éliminer la chaleur générée lors d'un processus de fonctionnement du module de source de lumière à DEL et du module laser. Le module de source de lumière à DEL et le module laser sont montés ensemble au moyen de la structure de coque de lampe. Le module laser présente une large quantité d'émission de lumière et présente une petite quantité de chauffage ; la quantité de chauffage de la lampe d'automobile est réduite tandis que la luminosité de la lampe d'automobile est améliorée ; de plus, le module de dissipation thermique configuré décharge efficacement la chaleur, générée lorsque le module de source de lumière à DEL et le module laser fonctionnent, hors de la structure de coque de lampe, l'accumulation de chaleur dans la structure de coque de lampe est évitée, et la longévité de la lampe d'automobile est prolongée efficacement. La lampe d'automobile présente une structure compacte, et le volume de produit est grandement réduit.
