Description

Technical Field

[0001] The utility model belongs to the technical field of motorcycle headlights, and in particular relates to a motorcycle LED energy-saving headlight structure. Background Art

[0002] Motorcycle headlights are the most basic lighting equipment. Their main function is to provide road lighting for drivers at night or in low-light environments to ensure driving safety. By emitting light, they illuminate the road ahead and potential obstacles, helping drivers identify road conditions.

[0003] Existing motorcycle headlights generate heat when working. If the heat dissipation area is insufficient, the heat cannot be dissipated in time, which will cause the temperature to rise. The heat dissipation design of traditional headlights simply uses heat sinks or fins, but the design area of ​​heat sinks or fins is limited, and they are too narrow or too thin, or no effective heat dissipation design is used, such as heat dissipation holes, heat dissipation fans, etc., which will affect the heat dissipation effect. In addition, due to the compact design of LED headlights, heat may accumulate inside the headlights, lacking effective convection and heat dissipation channels.

[0004] Motorcycles will experience vibrations and impacts during driving. A simple assembly process may lead to a decrease in structural stability without considering the wear and fatigue caused by long-term use. Motorcycles will experience bumps and vibrations during driving, which may cause internal components to loosen. Utility Model Content

The setting of the limiting ring 7 can also ensure that the transparent cover 6 will not be over-screwed during installation to prevent damage to the thread or affect the sealing effect.

[0041] A plurality of mounting plates B14 with holes are arranged in an equidistant manner in a circular manner at the front end of the housing 1 and at the rear side of the front docking ring 4. The mounting plates B14 with holes are conveniently installed in the motorcycle head housing.

[0042] The lamp holder 8 is provided with a low beam 15, a high beam 16, a fog lamp 17 and a night running lamp 18.

The heat dissipation fan 11 is fixed to the inner side of the heat dissipation plate 12, which helps to force air flow, take away heat, thereby improving the heat dissipation efficiency of the entire headlight and protecting the LED lamp from high-temperature damage.

[0049] The addition of the heat dissipation ribs 13 in the structure of the motorcycle LED energy-saving headlight expands the heat dissipation area and improves the heat dissipation efficiency. The design of the spliced heat dissipation cover 10 and the heat dissipation plate 12 improves the heat dissipation efficiency. The design of the heat dissipation holes A27, the heat dissipation holes B28 and the heat dissipation fan 11 increases air flow and further improves the heat dissipation effect.

[0050] The built-in reflective cup 2 enhances the focusing effect of the LED light, making the light more concentrated and illuminating the road ahead. The threaded connection between the transparent cover 6 and the front docking ring 4 and the design of the limit ring 7 improve the sealing performance and prevent rainwater and debris from entering.

[0051] The designs of the perforated mounting plates A3, B14, C20, D23, E24, F25 and G26 ensure the stability and reliability of each component, and the use of aluminum alloy materials increases the structural strength and thermal conductivity.
