Automobile turn signal lamp with easy heat dissipation

Abstract

The utility model relates to the technical field of automobile steering lamp, specifically disclose an automobile steering lamp easy to radiate heat, including lamp house, with the sealed connection of lamp house mask, and set up in the LED light source module of lamp house inside, the lamp house is made of metal material, its inner wall integrative forming has first radiating structure, its outer wall integrative forming has second radiating structure, through inside and outside double radiating fin structure, has promoted the radiating efficiency, utilizes the internal natural convection air duct formed by hot air ascending principle, has realized the initiative heat exchange of lamp house internal environment, effectively reduced internal environment temperature. The integrative forming metal lamp house and radiating structure eliminate the contact thermal resistance, have guaranteed the smooth transmission of heat flow. The dustproof and waterproof design of air inlet strengthens the heat dissipation while ensuring the sealing reliability of the lamp, the utility model controls the working temperature of high -power LED steering lamp, significantly delays the light decay, avoids the color drift, thereby greatly improves the long -term working stability and service life of product.
