[0022] The present invention will be further described below with reference to the accompanying drawings:

[0023] The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] like Figures 1 to 6 The present invention discloses a modified semi-LED front combination light, which features a brighter light source and lower costs. It includes an aluminum-based light-blocking plate 7, which is horizontally "T"-shaped. An LED light source 3 is fixedly connected to one side of the aluminum-based light-blocking plate 7. A reflector 5, also fixedly connected to the aluminum-based light-blocking plate 7, is located outside the LED light source 3. U-shaped heat sinks 4 are fixedly connected to both sides of the aluminum-based light-blocking plate 7 at the end opposite to the direction of the LED light source 3's illumination. Multiple U-shaped heat sinks 4 are perpendicular to the aluminum-based light-blocking plate 7, surrounding the LED light source 3. This allows the heat emitted by the LED light source 3 to be transferred laterally to the aluminum-based light-blocking plate 7, and then the aluminum-based light-blocking plate 7 transfers the heat to the U-shaped heat sinks 4, rapidly dissipating the heat and preventing damage to the LED light source 3 due to heat buildup, thus increasing its lifespan. One end of the reflector 5 has an LED lamp interface 12 electrically connected to the LED light source 3. One side of the LED lamp interface 12 abuts against the aluminum-based light-blocking plate 7, allowing for rapid heat transfer from the LED light source 3 to the aluminum-based light-blocking plate 7.

[0025] The U-shaped heat sink 4 is fixedly connected to the aluminum-based light-blocking plate 7 via a riveting structure. This fixing method provides greater stability and allows for a tighter connection between the U-shaped heat sink 4 and the aluminum-based light-blocking plate 7, resulting in faster heat transfer and improved heat dissipation efficiency. A glass lens bracket 8 is fixedly connected to the aluminum-based light-blocking plate 7 at one end of the LED light source 3's illumination direction. A glass lens 9 is fixedly connected to the side of the glass lens bracket 8 away from the LED light source 3. The glass lens 9 is fixedly connected to the glass lens bracket 8 via snap-fit ​​connections, and the glass lens bracket 8 is fixedly connected to the aluminum-based light-blocking plate 7 via self-tapping screws.

[0026] A lens assembly bracket 6 is fixedly connected to the outer side of the aluminum-based light-blocking plate 7. The lens assembly bracket 6 has multiple wire harness bundling holes 11 for securing the wire harness 2 and preventing it from moving during vehicle operation. A lamp holder 13 is fixedly connected to the outer side of the lens assembly bracket 6. A driver 1 is fixedly connected inside the lamp holder 13. The driver 1 controls the start / stop of the LED light source 3 and the illumination mode. Multiple wire harnesses 2 are electrically connected to the interface of the driver 1. A portion of the wire harnesses 2 are electrically connected to a power interface 10, while another portion passes through the wire harness bundling holes 11 on the lens assembly bracket 6 and is electrically connected to the LED lamp interface 12. The power interface 10 is fixedly connected to the rear of the lamp holder 13. The driver 1 is fixed inside the lamp holder 13 with self-tapping screws. The multi-strand wire harness 2 is fixed with cloth tape. The cloth tape is often used to fix the wire harness 2 in the vehicle body to reduce the abnormal noise caused by the movement of the wire harness 2 during vehicle operation. In addition, the cloth tape can protect the wire harness 2 from damage by wrapping and fixing it on the outside of the wire harness 2.

[0027] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
