The electromagnet 3 can drive the driving rod 7 to link the light-shaping plate 6 to the first position A (as shown in FIG. 6 ) or the second position B (as shown in FIG. 7 ) to change the reflected light of the LED light source 2 to form a low beam or a high beam. Specifically, the electromagnet 3 can drive the driving rod 7 to link the light-shaping plate 6 to rise and be located in the first position A. At this time, the shielding portion 62 of the light-shaping plate 6 rises to shield the light and form a low beam. The electromagnet 3 can drive the driving rod 7 to link the light-shaping plate 6 to descend and be located in the second position B. At this time, the shielding portion 62 of the light-shaping plate 6 descends without shielding the light and forms a high beam.

較佳的，該驅動桿7具有一樞接部71、一主動端72及一從動端73，該主動端72及從動端73連接於樞接部71的兩側，該樞接部71樞設於散熱裝置1的一樞軸13，使驅動桿7可轉動的設置於散熱裝置1上，該主動端72及從動端73分別連接於電磁鐵3與光形板6，亦即該主動端72可連接於電磁鐵3的動作桿31，該從動端73可連接於光形板6的連動部63，在本實施例中，主動端72抵觸電磁鐵3的動作桿31，從動端73抵觸光形板6的連動部63，可使組裝簡單容易，並形成一較佳的傳動結構。Preferably, the driving rod 7 has a pivot portion 71, an active end 72 and a driven end 73, the active end 72 and the driven end 73 are connected to the two sides of the pivot portion 71, the pivot portion 71 is pivoted on a pivot shaft 13 of the heat sink 1, so that the driving rod 7 can be rotatably arranged on the heat sink 1, and the active end 72 and the driven end 73 are respectively connected to the electromagnetic Iron 3 and light-shaped plate 6, that is, the active end 72 can be connected to the actuating rod 31 of the electromagnetic iron 3, and the driven end 73 can be connected to the connecting part 63 of the light-shaped plate 6.

該電磁鐵3啟動時，該動作桿31能通過驅動桿7驅動光形板6動作，使該光形板6位於第一位置Ａ或第二位置Ｂ。較佳的，該主動端72能沿著一左右方向C移動(如圖4所示)，該從動端73能沿著一前後方向D移動，亦即該主動端72能被電磁鐵3的動作桿31推動而沿著左右方向C移動，該從動端73能沿著前後方向D移動而推動光形板6的連動部63，使該電磁鐵3的動作桿31得以通過驅動桿7驅動光形板6動作，且能改變電磁鐵3及光形板6動力傳輸方向，使得電磁鐵3與光形板6的配置更具彈性，且能使得電磁鐵3可以採用臥式橫置於散熱裝置1的前端，以節省占用的空間，並可使整體高度降低。When the electromagnet 3 is activated, the actuating rod 31 can drive the light-shaping plate 6 to move via the driving rod 7, so that the light-shaping plate 6 is located at the first position A or the second position B. Preferably, the active end 72 can move along a left-right direction C (as shown in FIG. 4 ), and the passive end 73 can move along a front-back direction D, that is, the active end 72 can be pushed by the actuating rod 31 of the electromagnet 3 to move along the left-right direction C, and the passive end 73 can move along the front-back direction D to push the connecting portion 63 of the light-shaping plate 6, so that the actuating rod 31 of the electromagnet 3 can drive the light-shaping plate 6 to move through the driving rod 7, and can change the power transmission direction of the electromagnet 3 and the light-shaping plate 6, so that the configuration of the electromagnet 3 and the light-shaping plate 6 is more flexible, and the electromagnet 3 can be horizontally placed at the front end of the heat dissipation device 1 to save the occupied space and reduce the overall height.

該光形板6在第一位置A時，該LED光源2發出的光線在經反射鏡組4的反射面41反射時被遮蔽(如圖6所示)，能產生近光的光形。該光形板6在第二位置B時(如圖7所示)，該LED光源2發出的光線在經反射鏡組4的反射面41反射時不被遮蔽，能產生遠光的光形。When the light-shaping plate 6 is in the first position A, the light emitted by the LED light source 2 is shielded when reflected by the reflective surface 41 of the reflector assembly 4 (as shown in FIG. 6 ), and a low-beam light shape can be generated. When the light-shaping plate 6 is in the second position B (as shown in FIG. 7 ), the light emitted by the LED light source 2 is not shielded when reflected by the reflective surface 41 of the reflector assembly 4, and a high-beam light shape can be generated.
