The invention discloses an LED automobile headlamp capable of dynamically adjusting the light color temperature, and belongs to the technical field of automobile lighting equipment. The LED automobile headlamp comprises a lampshade, a red LED lamp bead, a green LED lamp bead, a blue LED lamp bead and a control module. The red LED lamp bead, the green LED lamp bead and the blue LED lamp bead are fixed to the inner surface of the lampshade together through installation stand columns. The control module is installed at the rear end of the lampshade. An LED lamp bead control circuit and a stepping motor control circuit are arranged inside the control module. According to the LED automobile headlamp capable of dynamically adjusting the light color temperature, when it is foggy, rainy or normal, the good visual effect and the good illumination distance can be provided for a driver, and road accidents caused when illumination of the automobile headlamp is insufficient can be effectively reduced.
Description
technical field [0001] The invention belongs to the technical field of automotive lighting equipment, and relates to an automotive headlight, in particular to an LED automotive headlight that can dynamically adjust the color temperature of light. Background technique [0002] Car headlights are installed at the front of the car body and are used at night or in environments with poor light. Therefore, the lighting effect of car headlights is an important factor that affects the safe driving of cars in dark environments. The lighting effect of car headlights is determined by factors such as lamp brightness and color temperature. If the lighting effect of car headlights is not ideal, it will affect the driver's accurate judgment of obstacles in the dark environment, thereby causing traffic accidents. At present, most car headlights use HID xenon lamps, LEDs, and halogen lamps for lighting, and use fixed color temperature technology, which cannot dynamically change the color tem...
