Problems solved by technology

Existing headlights all use filament bulbs, which have the following disadvantages: 1. Filament bulbs need to be welded to the bracket in the lamp body because the tungsten wire is very thin, and the welding is easy to cause damage to the filament. When affected, the filament is easily deformed, and the headlight is a point light source, which has high requirements for the geometric size of the light-emitting point. After the filament is deformed, the light shape of the lamp will change, changing the light performance; 2. Due to the output voltage of the vehicle The fluctuation of the tungsten filament is very thin, which is easy to break and cause failure; 3. The filament bulb uses a glass shell, which is easy to break

preparation example Construction

[0069] The preparation method of the radiator material is as follows: put the above-mentioned components in a high-temperature smelting furnace, raise the temperature of the furnace body to 500-520°C, melt for 2-2.5 hours, and then anneal and cool after the smelting to obtain the radiator material .

[0070] In another technical solution, an insulating layer is provided on the surface of the middle part of the radiator with a thickness of 2-3 mm;

[0071] The insulating layer is made of the following raw materials in parts by weight: 100 parts of silicon carbide, 20-25 parts of binder, 20-25 parts of clay and 8-12 parts of aluminum oxide.

[0072] In the above technical solution, after the insulating layer is provided, the first substrate and the second substrate are fixed on the insulating layer, and the heat of the LED headlight is transferred to the radiator through the insulating layer.

[0073] In another technical solution, the middle part of the heat sink is configured...

Embodiment 1

[0075] According to the material of this application, the radiator is made of the following components in parts by weight:

[0076] 50 parts AL, 20 parts AlB 12 , 8 parts of tin oxide, 5 parts of carbon steel, 0.5 parts of palladium, 3 parts of spinel, and 3 parts of Ni.

[0077] The preparation method of the radiator material is as follows: put the above-mentioned components in a high-temperature melting furnace, raise the temperature of the furnace body to 500° C., melt for 2 hours, and then anneal and cool after melting to obtain the radiator material.

[0078] The surface of the middle part of the radiator is provided with an insulating layer with a thickness of 2 mm.

[0079] The insulating layer is made of the following raw materials in parts by weight: 100 parts of silicon carbide, 20 parts of binder, 20 parts of clay and 8 parts of aluminum oxide.

Embodiment 2

[0081] It manufactures the radiator according to the standard of Example 1, the only difference is that the middle part of the radiator is arranged as a honeycomb structure.

[0082] Control group 3

[0083] The size and shape of the radiator made by it are the same as that of embodiment 1, and the selected material is made of aluminum with a thermal conductivity of 3.0.

Abstract

The invention discloses an LED vehicle headlamp. The LED vehicle headlamp comprises a first substrate, a second substrate, LED light sources and a pair of light distribution screens, wherein the first substrate is provided with a surface A, and the second substrate is provided with a surface B which is symmetrical with and backs onto the surface A of the first substrate; the LED light sources include the first LED light source, the second LED source, the third LED light source and the fourth LED light source, the first LED light source and the second LED light source are linearly arranged on the surface A of the first substrate, the third LED light source and the fourth LED light source are linearly arranged on the surface B of the second substrate, the first LED light source and the third LED light source are arranged oppositely, and the second LED light source and the fourth LED light source are arranged oppositely; the light distribution screens are oppositely arranged on the surface A of the first substrate and the surface B of the second substrate correspondingly and form a bowl-shaped structure on the whole; and the first LED light source is located on the bowl plane of the light distribution screen on the surface A, and the third LED light source is located on the bowl plane of the light distribution screen on the surface B. By adoption of the LED vehicle headlamp, the problems of unclear brightness-darkness deadlines and dazzling of high and low beams are solved.

Description

technical field [0001] The invention relates to the field of vehicle lights. More specifically, the present invention relates to an LED vehicle headlamp. Background technique [0002] The headlight light source is a key component on the vehicle, and it is a unified standard component. The GB15766 national standard, IEC-60809, and R37 European standards all have standard requirements for product specifications and models. Existing headlights all use filament bulbs, which have the following disadvantages: 1. Filament bulbs need to be welded to the bracket in the lamp body because the tungsten wire is very thin, and the welding is easy to cause damage to the filament. When affected, the filament is easily deformed, and the headlight is a point light source, which has high requirements for the geometric size of the light-emitting point. After the filament is deformed, the light shape of the lamp will change, changing the light performance; 2. Due to the output voltage of the v...
