Description

H4 car LED headlight

technical field

The utility model relates to an H4 automobile headlight, in particular to an H4 automobile LED headlight.

Background technique

Car headlights, also known as car headlights, as the eyes of a car, are not only related to the external image of a car, but also closely related to driving at night or driving safely under bad weather conditions.

LED headlights are not easily affected by vibration, and the light output brightness will not decrease significantly during use. LED car lights have the characteristics of energy saving, environmental protection and long life. The structure that existing automotive LED headlights adopts is that the power supply is arranged in the lamp panel, and the power supply and the lamp body are integral structures, so the heat dissipation effect is poor, and the service life of the headlights is short.

Contents of the invention

In order to overcome the existing problems in the prior art, the purpose of this utility model is to provide a kind of automobile LED headlight, this headlight adopts the separation structure of power source and lamp body, heat dissipation effect is good, and the service life of headlight is long.

The purpose of this utility model is achieved through the following technical solutions:

A kind of H4 automotive LED headlight, comprising a lamp housing, a lamp holder and an LED device arranged in the lamp housing, characterized in that: the lamp housing is made of transparent material, a copper rod is arranged in the lamp housing, and A heat-dissipating aluminum sheet with heat dissipation holes at the bottom is provided on the outside of the seat, and the copper rod is arranged on the lamp holder and connected with the heat-dissipating aluminum sheet; a flexible flexible circuit board is provided on the copper rod, and the LED device is mounted on the flexible flexible circuit board; The flexible flexible circuit board is connected to the external power supply through the heat dissipation holes on the heat dissipation aluminum sheet through the wires.

In the utility model, flexible flexible circuit boards are arranged on the corresponding two sides of the red copper rod, and LED devices are arranged on the flexible flexible circuit boards. There is a lamp panel at the junction of the copper rod and the heat dissipation aluminum sheet.

The utility model has the following characteristics:

Energy saving: The utility model LED lamp only has 30W, and the traditional tungsten filament lamp is at least 60W. Lifespan: The lifespan of LED bulbs can reach 30,000 hours, while the lifespan of ordinary tungsten filament bulbs is only about 300 hours. Voltage: LED bulbs can be 12V and 24V universal, but ordinary tungsten bulbs can only be 12V or 24V, not universal. Positive and negative poles: LEDs can be made regardless of positive and negative poles, but ordinary tungsten filament bulbs must be polarized. Light color: LED light color is soft, not dazzling, and can be divided into multiple color temperatures, such as cool color 6500K, normal solar color 6000K, and tungsten filament bulb only solar color 6000K. Brightness: The LED lamp has 1800 lumens, while the brightness of this tungsten bulb is only 1500 lumens. Temperature: The temperature of the LED bulb is touchable, and an aluminum radiator is installed. The traditional tungsten lamp has high temperature and heat, so it cannot be touched.

The utility model adopts the separation structure of the power supply and the lamp body, has good heat dissipation effect, and has long service life of the front headlight.

Detailed ways

An H4 automotive LED headlight, comprising a lamp housing 1, a lamp holder 2 and an LED device 3 arranged in the lamp housing. The lamp housing is made of transparent material, and a red copper rod 4 is arranged inside the lamp housing. A heat-dissipating aluminum sheet 5 with heat dissipation holes at the bottom is provided, and the copper rod is arranged on the lamp holder and connected to the heat-dissipating aluminum sheet; a flexible flexible circuit board 6 is provided on the copper rod, and the LED device is mounted on the flexible flexible circuit board; The flexible flexible circuit board is connected to the external power supply through the heat dissipation holes on the heat dissipation aluminum sheet through the wires.

The utility model adopts the transparent appearance design of the traditional tungsten filament bulb, and the external lamp housing can be made of glass or transparent plastic. The lamp housing is equipped with 3 pieces of 10W CREE new SMD patch lamps each, divided into two sides, one side is 2SMD, One side is 1SMD, 3SMD are pasted on the flexible flexible circuit board, and then the circuit board is pasted on both sides of the copper rod in the middle of the glass, and the copper rod is connected to the heat dissipation aluminum sheet with cooling holes at the bottom. The rings are interlocked, and then fastened with screws. The line connected from the circuit board on the copper rod is connected to the external power supply and interface through the central cooling hole of the heat dissipation aluminum sheet, so that the power supply is separated from the lamp body, ensuring that the lamp body In the case of overheating, the working capacity of the power supply will not be aggravated, and damage to components will also be avoided. At the junction of the copper rod and the heat-dissipating aluminum sheet, install the same lamp panel as the original halogen tungsten lamp H4 to form a complete car LED headlight.

The height of the light center of the utility model is the same as that of the original tungsten filament bulb, and the overall light effect of the light pattern is good. With the help of the copper rod and the heat dissipation aluminum, the heat dissipation function is better, which ensures the long life of the product. At the same time, the transparent lamp shell makes the LED light 360 degrees. Luminous, spherical irradiation without dead angle, no need to install any parts, can directly replace the original tungsten filament bulb, with a lifespan of up to 30,000 hours.
