Description

A kind of high-power LED automobile headlight

technical field

The utility model relates to an automobile headlight, in particular to an automobile headlight using a high-power light-emitting diode as a light source, and belongs to the field of LED lighting.

Background technique

LED is attractive and has many advantages. In addition to long life and low energy consumption, LEDs have four major advantages: first, the application is very flexible, and can be made into light, thin and short products in various forms of points, lines, and surfaces; second, the environmental protection benefits are better. There is no ultraviolet and infrared rays, neither heat nor radiation. It is a typical green lighting source, and the waste can be recycled without pollution. Third, it has high luminous efficiency and low power consumption, which can save energy. Fourth, the color rendering is good, the white light is more pure, and it is easier for people to distinguish when it shines on the object.

As the performance and efficiency of LED products are gradually recognized by people, they have also been widely used. With the support of intelligent drivers, LED lighting fixtures can not only replace fluorescent lighting, but also achieve new functions. The original car headlight light source is a traditional light source with low luminous efficiency and relatively low color rendering. And high-power LED can fill this gap completely. Its high efficiency, energy saving, environmental protection and other characteristics can make up for the shortcomings of traditional light sources.

Contents of the invention

The technical scheme of the utility model is: a high-power LED automobile headlight, which includes a mask 1, a lamp board 3, a constant current power supply 4, a lamp housing 2 and a radiator 5 in sequence; the mask 1 and the lamp housing 2 connect the lamp board 3 is sealed inside, the lamp board 3 is connected to the constant current power supply 4 through wires, and is located at the inner rear end of the lamp housing 2; a radiator 5 is fixed outside the rear end of the lamp housing 2; A circuit board is installed with a high-power LED; the constant current power supply 4 is DC12V.

The number of LEDs is 3 or 6, the color temperature is 3000K-6500K, and the luminous efficiency of a single LED is greater than 100lm/w.

The lamp housing 2 is a metal structure, which can dissipate heat to the LED through the housing.

The lamp housing 2 and the radiator 5 are fixed by heat-conducting glue. The radiator 5 is an aluminum radiator with a base, and an electric motor fan is installed at the rear end.

The utility model is a vehicle-mounted device, which uses a power supply to supply power to a car storage battery, and a constant voltage source of DC12V is input, and the constant current power supply is converted into a horizontal constant current to supply power to a high-power LED lamp.

Because high-power LEDs will generate a lot of heat when they work, if the heat cannot be dissipated in time, it will have a great impact on the luminous efficiency and even the life of the LED. The utility model produces and uses the method for external radiator 5 to protect. Firstly, the high-power LED is welded on the aluminum substrate with good thermal conductivity, and the space between them is filled with thermal conductive silicone grease to achieve better thermal conductivity. Then they are fixed on the metal casing 2, and the heat is dissipated into the air through the radiator 5.

The utility model adopts a high-power light-emitting diode (LED) as a light source, and has a fully enclosed structure. It has good color rendering, lightness and convenience, sealing and waterproof, strong corrosion resistance, LED light source, energy saving, long life, environmental protection and other excellent features.
