Description
技术领域technical field
本发明涉及一种适用于汽车灯具的风扇散热结构。The invention relates to a fan cooling structure suitable for automobile lamps.
背景技术Background technique
在汽车照明灯具设计中，随着LED大灯越来越普及，利用风扇散热是一个重要的手段，风扇通常紧贴LED模组，如图1-4所示，虽然风扇的效率较高，但由于对风扇的寿命要求较高(即要求风扇的寿命大于或等于整车的寿命)，因此一旦风扇在整车寿命期间发生故障，很有可能造成灯具的性能下降或者LED过热烧毁，从而影响行驶安全。In the design of automotive lighting fixtures, as LED headlights become more and more popular, using fans to dissipate heat is an important means. Fans are usually attached to LED modules, as shown in Figure 1-4. Although the efficiency of fans is high, the Due to the high requirements on the life of the fan (that is, the life of the fan is required to be greater than or equal to the life of the vehicle), once the fan fails during the life of the vehicle, it is likely to cause the performance of the lamp to decline or the LED to overheat and burn, thus affecting driving. Safety.

所述风扇可以通过触点接触或者接插件连接的方式接通电源。The fan can be powered on through contact or connector connection.
所述灯体内安装有LED发光模组，所述LED发光模组上LED所在端朝向所述风扇的出风口，所述风扇通过触点接触或者接插件连接的方式接通电源。An LED light-emitting module is installed in the lamp body, and the end of the LED light-emitting module where the LED is located is facing the air outlet of the fan, and the fan is powered on through contact contact or connector connection.
所述后盖可以通过螺钉或者卡扣固定连接在所述灯体上。The rear cover can be fixedly connected to the lamp body through screws or buckles.
所述风扇提前预装在所述后盖的内侧形成带风扇的集成后盖。The fan is pre-installed on the inner side of the rear cover to form an integrated rear cover with a fan.
本发明的有益效果是：The beneficial effects of the present invention are:
由于风扇和后盖提前预装配在一起，安装时候只需安装后盖就可以把风扇同时安装到位，且风扇可以通过触点接触或者接插件连接的方式接通电源，安装方便、快捷。Since the fan and the back cover are pre-assembled together, the fan can be installed in place at the same time only by installing the back cover during installation, and the fan can be connected to the power supply through contact contact or connector connection, which is convenient and fast to install.
由于通过替换带风扇的后盖就可以对风扇进行维修或更换，大大降低了灯具因为风扇可靠性带来的维修成本。Since the fan can be repaired or replaced by replacing the rear cover with the fan, the maintenance cost of the lamp due to the reliability of the fan is greatly reduced.
