Description

Modular LED headlights for vehicles

This creation belongs to the field of automotive lighting equipment, and in particular to a modular automotive LED headlight, which can be used to change the model of the different lamp housings and the color temperature when used.

According to the vehicle, the most important thing when driving at night is the good lighting design. In addition to providing the driver with a good lighting vision, it can also be used to remind the car. However, the current headlight bulb models are available in seven sizes, H1, H3, H4, H7, H11, HB3 (9005) and HB4 (9006), which are distinguished by the shape of the base and the number of legs. Among them, H1, H4, H7 bulbs are all round metal bases, H1 is a single lamp foot, H4 is a three-lamp leg, H7 is a double lamp foot; and, for the convenience of identification, the circular metal base of the H1 specification bulb There are no protruding teeth on one side, and there are three raised teeth on the outer circumference of the circular metal base of the H4 size bulb. The circular metal base of the H7 size bulb has only one protruding tooth on one side. The specifications of the H11, HB3 (9005) and HB4 (9006) bulbs are made of plastic bases, and there are different numbers of small convex teeth inside the interface. The H11 bulb has a long tooth protruding from the lower edge, HB3 The bulb protrudes from the upper edge by two short teeth, and the bulb of HB4 has a short tooth protruding from the upper edge.
