Automobile LED headlamp

Abstract

The invention discloses an automobile LED headlamp. The automobile LED headlamp comprises a shell, a chuck, a light-emitting groove, light source plates, light-emitting bodies, a heat pipe, a copper pipe, a radiator, a fan and a driver. The shell is of a cavity structure with the upper end hollowed out and the bottom end open; the heat pipe, the light source plates and the copper pipe are arrangedin the shell; the light source plates are located on the two sides of the heat pipe and closely connected with the heat pipe; the light-emitting bodies are arranged on the light source plates; the lower end of the heat pipe is fixedly connected with the copper pipe; the lower end of the shell is fixedly connected with the radiator; the fan is arranged below the radiator, and the outer side of thefan is connected with a fan cover; and the chuck is connected to the middle of the shell in a sleeving mode. The automobile LED headlamp has the beneficial effects that the automobile LED headlamp adopts the modes of external driving and heat pipe heat conduction, and has the advantages of small size and good heat dissipation, and the service life of the automobile LED headlamp is prolonged.

Description

technical field [0001] The invention relates to the fields of lamps and automobile manufacturing, in particular to an automobile LED headlamp. Background technique [0002] Now on the market, there are mainly halogen lamps, HID xenon lamps and LED lamps for cars. Among them, the life of the halogen lamp is short, the luminous efficiency is not high, the brightness is relatively low, and the heat is also large; the life of the xenon lamp is longer than that of the halogen lamp. It has increased by about 6 times, but the power is large and the heat generation is large, the battery power consumption increases, the light penetration is poor, and the start-up time is also long; as a new generation of light source, LED has high efficiency, environmental protection, energy saving, and long life. Long, instant lighting and other characteristics, the service life of LED is greatly improved than that of halogen lamps and xenon lamps. Obviously, LED lighting has advantages in various a...

Problems solved by technology

[0002] Now on the market, there are mainly halogen lamps, HID xenon lamps and LED lamps for cars. Among them, the life of the halogen lamp is short, the luminous efficiency is not high, the brightness is relatively low, and the heat is also large; the life of the xenon lamp is longer than that of the halogen lamp. It has increased by about 6 times, but the power is large and the heat generation is large, the battery power consumption increases, the light penetration is poor, and the start-up time is also long; as a new generation of light source, LED has high efficiency, environmental protection, energy saving, and long life. Long, instant lighting and other characteristics, the service life of LED is greatly improved than that of halogen lamps and xenon lamps. Obviously, LED lighting has advantages in various aspects; There are strict requirements, but the shortcomings of the current products on the market are: the size is too large, which makes the installation of LED lights inconvenient, and the compatibility is poor, which makes many cars unable to install

In addition, the heat dissipation ability is poor, causing the LED lights to be in a high temperature state for a long time when they are working, resulting in large light decay and greatly reducing the service life of the LED lights

Moreover, considering the heat dissipation problem of LED car lights, under the condition of ensuring the normal operation of LED car lights, LED car lights often cannot have high power, resulting in insufficient power and brightness of LED car lights, and cannot achieve good lighting. Effect
