Problems solved by technology
Due to the different characteristics of the two color temperature light sources, there are also many automotive headlight products with two different color temperatures on the market, or some products that change the color temperature of the headlights through a color-changing film device, but these products switch between the two color temperatures. Complicated operation, extremely inconvenient and not fast

Embodiment Construction
[0028] The principles and features of the present invention are described below, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0029] Such as Figure 1-Figure 3 As shown, a kind of dual-color temperature switching automotive LED headlights, including the car light body and the far and near beam switching switch installed in the cab, used to switch the output far and near beam signals; High and low light switching switch, no additional components.
[0030] Installed on the car, used to drive the LED driving device of the car headlight;
[0031] The LED driving device includes a control circuit module, which is used to receive the switching signal of far and low beams, and output a control signal to control the driving circuit module;
[0032] The driving circuit module is used to drive the white high beam LED lamp, the yellow high beam LED lamp, the white low beam LED lamp or the yell...

The invention relates to an automotive LED headlamp with a dual-color-temperature switching function. The automotive LED headlamp comprises an automotive lamp body, a distant light and short-distance light selector switch and an LED driving apparatus; the LED driving apparatus comprises a control circuit module used for receiving a distant light and short-distance switching signal and outputting a control signal to control a driving circuit module; and the driving circuit module drives a white high beam LED light, a yellow high beam LED light, a white dipped beam LED light or a yellow dipped beam LED light to work according to the control signal. Based on the scheme, a driver can switch lamplights of two color temperatures by only regulating the headlamp switch in the cabin; the simple, convenient and quick operation does not influence the luminous effect; loading or replacing of any equipment by opening an engine cabin to change the color temperatures of the light source is not needed; white light and yellow light can be switched quickly for illumination; and therefore, the driver can choose the light source with the proper color temperature to perform road illumination conveniently according to different weather and road conditions.
Description
technical field [0001] The invention relates to the technical field of control, in particular to an automobile LED headlight with dual color temperature switching, which is applied to vehicle lighting. Background technique [0002] The current automotive LED headlights use a single color temperature light source of 3000K-3500K yellow light or 6000K-6500K white light (6000K-6500K white light is more popular), and the two color temperature light sources have their own advantages and disadvantages. White light has higher illuminance, stronger lighting ability under normal weather conditions and road conditions, and white light is more fashionable and popular among young people. Yellow light has a short wavelength and strong penetrating ability, and can maintain a relatively high lighting effect in rainy, foggy and snowy days with harsh weather conditions. Due to the different characteristics of the two color temperature light sources, there are also many automotive headlight p...
