The invention is applicable to the field of vehicle logo lamps, and provides a light-emitting vehicle logo lamp capable of penetrating radar waves, the vehicle logo lamp sequentially comprises a bottom shell, a cooling fin, a circuit board, a light guide plate and a mask from bottom to top, and each of the cooling fin and the circuit board is of an annular structure with an opening in the center. The cooling fin and the circuit board are both of an annular structure, the LED lamps are arranged at the edge of the circuit board, light enters from the light inlet part and then is reflected to the main body part, the light irradiates on an optical surface in the main body part to achieve light emitting, the light is uniform and high in brightness, the overall structural design is simple, and production and installation are convenient. Meanwhile, the centers of the circuit board and the cooling fin are open, the radar is installed at the position of an automobile head behind the logo lamp, and radar waves can penetrate out of the center of the circuit board; in addition, in a preferable structure, the vehicle logo lamp cover is provided with an+ indium plating layer, radar wave emission is not affected, and the vehicle logo lamp has good metal texture, so that the vehicle logo lamp can penetrate through radar waves, the structure is more compact, and the size of the vehicle logo lamp is reduced.
本发明适用于车标灯领域,提供一种穿透雷达波的发光车标灯,车标灯从下至上依次为底壳、散热片、电路板、光导板和面罩,所述散热片和电路板均为中央开口的环形结构。散热片、电路板均为环形结构,LED灯布置在电路板边缘位置,光线从进光部进入然后反射至主体部,光线在主体部内照射在光学面上进而实现发光,光线均匀,亮度高,整体结构设计简单,便于生产和安装;同时电路板、散热片中央开口,雷达安装在车标灯后方的汽车车头位置,雷达波可以从电路板中央穿出;另外在优选结构中,车标灯面罩有镀铟层,不影响雷达波发射,且具有很好金属质感,因此本车标灯可以穿透雷达波,结构也更为紧凑,减小了车标灯体积。
