The utility model discloses a LED car lamp, including a heat conduction plate. The heat conduction plate is fixed and connected with a LED light source plate. The rear end of the heat conduction plate is fixedly connected with a clamp seat and a radiator. The rear end of the radiator is fixed with a cooling fan, and the radiator is provided with a through front end face. The heat conducting plate is provided with a guide groove which passes through the front and rear ends, and the guide groove is communicated with the concave cavity. During the use of the utility model, the rotation of the cooling fan will not only take away the heat of the heat transfer plate to the radiator, but also, as the guide slot is connected with the concave cavity, the heat generated by the LED light source plate is transferred to the inner surface of the guide slot, and the heat dissipation speed is speeded up, at the same time, due to the shadow of the air flow in the guide slot. The heat emitted by the LED light board will also be partly removed from the air stream, which will further improve the speed of heat dissipation and improve the heat dissipation effect.

一种中空导风散热式的LED汽车灯
本技术涉及一种LED汽车灯,具体涉及一种中空导风散热式的LED汽车灯。
技术介绍
LED灯在汽车上的应用已经是越来越普遍。LED汽车灯在使用过程中会产生较大的热量,为保证在汽车车头有限的空间内LED灯也能够正常使用,现有的LED汽车灯采取了必要的散热措施进行有效的散热,例如在LED灯座的后面加设散热风扇,其结构一般包括LED光源板、用于安装LED光源板的导热板、设置在导热板后端的卡座、与导热板后端固定连接的散热器以及设置在散热器后端的散热风扇,使用中LED光源板产生的热量通过导热板传递到散热器,风扇转动带动空气流动进而快速带走热量。这种设计中导热板为实心结构,热量只能通过热传递到散热器,速度较慢,而且LED光源板和导热板散发到周围的热量也难以传递出去,散热效果不佳。
