(22) The light emitted by the LED light source 2 can be reflected by the reflective surface of the light-reflecting assembly 4, and then emit to the outside through the lens assembly 5. In this embodiment, the light generated by the LED light source 2 is reflected by the lower reflecting seat 41 to form a high beam (i.e., far light), and the light generated by the LED light source 2 is reflected by the upper reflecting seat 42 to form a low beam (i.e., near light).

(28) The active side 72 is connected to the electromagnet 3, and the driven side 73 is connected to the light-shaping plate 6. That is to say, the active side 72 can be connected to the actuating rod 31 of the electromagnet 3, and the driven side 73 can be connected to the linkage portion 63 of the light-shaping plate 6. In this embodiment, the active side 72 is abutted against the actuating rod 31 of the electromagnet 3, and the driven side 73 is abutted against the linkage portion 63 of the light-shaping plate 6, which makes assembly simple and easy so as to form a better transmission structure.
(29) More particularly, when the electromagnet 3 is activated (turned on), the actuating rod 31 can reciprocatingly move along the X-axis by cooperation of the horizontal electromagnet 3 so as to push the active side 72 to move left and right along the X direction, so that the pivot portion 71 of the driving rod 7 can be rotated along the Z-axis direction, and finally make the driven side 73 move back and forth along the Y-axis so as to push the linkage portion 63 of the light-shaping plate 6. Thereby, the actuating rod 31 of the electromagnet 3 can drive the light-shaping plate 6 through the driving rod 7 so as to move the light-shaping plate 6 to the first position (as shown in
(30) The structure of the driving rod 7 of the present embodiment can change the actuating direction of the electromagnet 3. Described by another angle, the active side 72 can be moved along a direction (i.e., the left and right direction or the X-axis direction as shown in
(31) The advantage of the above structure of the embodiment is that the electromagnet 3 can be placed horizontally on the front side of the heat-dissipating device 1, which can save space (or reduce occupied space) and reduce the overall height. The light-shaping plate 6 can swing back and forth along the rotating shaft 61 through the driving rod 7 due to the movement of the electromagnet 3 along the horizontal direction, so that the structural configuration of the electromagnet 3 and the light-shaping plate 6 is more compact.
