The strip reflective lens 118 is elastically rotatably arranged on the reflective lens bracket 119 through the torsion spring, and the strip reflective lens 118 can swing on the reflective lens bracket 119.

The guide frame cover 112 is rotatably mounted with a gas turbine 113, and a heat sink 114 is arranged on the side of the guide frame cover 112. The heat sink 114 is fixedly mounted on the lower surface of the light-emitting diode 115 to absorb the heat of the light-emitting diode 115, and the guide frame cover 112 is used to guide the airflow generated by the gas turbine 113 to the heat sink 114.Two parallel arch frames 106 are fixedly mounted on the mounting base 101, a lens frame slide bar 130 is fixedly mounted between the two arch frames 106, a convex lens frame 107 is fixedly mounted on the lens frame slide bar 130, and a convex lens 108 is fixedly mounted on the convex lens frame 107.

An adjustment belt 103 is rotatably mounted on the two arch frames 106, one side of the adjustment belt 103 is fixedly matched with the concave lens frame 109 by toggling the connecting block 111, and is used to drive the concave lens frame 109 to slide on the lens frame slide bar 130; an adjustment servo motor 105 is also fixedly arranged on the mounting base 101, and the output shaft of the adjustment servo motor 105 drives the adjustment belt 103 to rotate through the intermediate transmission belt 104.

[0025] The working principle of a front combination light dynamic lighting system disclosed in the present invention is as follows: when the light emitting diode 115 is working, a large amount of heat will be generated, and the heat will be transferred to the heat sink 114, and then the gas turbine 113 will be started, and the gas turbine 113 will push the airflow to blow to the heat sink 114 after passing through the guide frame cover 112, so as to dissipate the heat of the heat sink 114, and then reduce the temperature of the light emitting diode 115. The light generated by the light emitting diode 115 when working will be blocked by the light shielding plate 126. When the light shielding plate 126 is in a flipping state (the light shielding plate 126 is in contact with the limit stopper 125, the bottom electromagnet 127 is in a power-on state, and the bottom electromagnet 127 generates a magnetic force to repel the light shielding plate 126), the light will irradiate the strip-shaped reflective lens 118, and the strip-shaped reflective lens 118 will reflect the light, and the light will pass through the convex lens 108 and the concave lens 110 in sequence, and then be emitted to the outside.

[0026] During this process, if there is a vehicle in front, the top electromagnet 121 of the corresponding height is started, and the top electromagnet 121 generates magnetic force to attract the passive magnetic block 122. The passive magnetic block 122 drives the strip reflective lens 118 to swing, so that part of the light cannot be reflected on the convex lens 108. Therefore, a dark light will appear in front (the position of the human eye to prevent glare). When the top electromagnet 121 is powered off, the strip reflective lens 118 will be reset under the action of the torsion spring (the reflective lens bracket 119 is provided with a limit pad 131 for limiting the swing angle of the strip reflective lens 118). At the same time, according to the horizontal position, the corresponding bottom electromagnet 127 is turned off. After the bottom electromagnet 127 is powered off, it no longer repels the shading plate 126. Therefore, the shading plate 126 is reset under the action of gravity, thereby blocking the light emitted by the light-emitting diode 115, achieving the effect of dimming the light at the required position, and through the on-off combination of the bottom electromagnet 127 at different positions, whether the shading plate 126 at the corresponding position is in the open state is controlled, and different projection patterns (such as turn prompts and pedestrian courtesy prompts) can be set.

[0027] After the light is reflected from the strip reflective sheet 118 onto the convex lens 108, it will be focused by the convex lens 108 (the focal point of the convex lens 108 is located on the outside away from the concave lens 110), and then pass through the concave lens 110. The concave lens 110 diffuses the light emitted from the convex lens 108. The specific diffusion angle depends on the incident angle. Therefore, by adjusting the distance between the convex lens 108 and the concave lens 110, the illumination range of the final light emission can be adjusted. Specifically, the servo motor 105 is controlled and adjusted. The output shaft of the servo motor 105 drives the adjustment belt 103 to rotate through the intermediate transmission belt 104. The adjustment belt 103 drives the concave lens frame 109 to slide on the lens frame slide bar 130 by toggling the connecting block 111. The concave lens frame 109 drives the concave lens 110 to approach or move away from the convex lens 108, thereby adjusting the distance between the convex lens 108 and the concave lens 110, and then adjusting the illumination range of the final emitted light.
