Description

Technical Field

[0002] H4 car LED headlights are a type of bulb used for car lighting. They directly convert electrical energy into light energy through semiconductor materials. Compared with traditional halogen headlights, H4 car LED headlights have higher brightness, can provide clearer and farther lighting vision, and improve driving safety; at the same time, they have lower energy consumption, can reduce the car's electrical energy consumption, and are helpful to the vehicle's fuel economy.

[0003] There are many styles of H4 automotive LED headlights, among which the most widely used style is the plug-in type. The tail end of the plug-in H4 automotive LED headlight is usually provided with a plug for electrical connection, which has the characteristics of convenient installation and strong adaptability; because the tail end of the plug-in H4 automotive LED headlight is a plug, that is, its cooling fan is usually installed at the bottom of the main frame. When the LED lamp beads are in use, the heat generated is transferred from the lamp board to the main frame in the form of heat conduction, and is dissipated by the heat sink and cooling fan on the bottom side of the main frame. Since the cooling fan can only dissipate heat on one side of the bottom of the main frame, it is difficult to quickly dissipate heat on the top surface of the lamp board, and the temperature is prone to overheating. Therefore, in view of this, the existing structure and defects are studied and improved, and an LED automotive headlight is provided to achieve a more practical purpose. Utility Model Content
