Abstract

The invention discloses a vehicle lamp light color conversion device and method. The device comprises a PCB and a white light LED, the right side of the top surface of the PCB is electrically connected with the white light LED, the top transmission end of the white light LED is electrically connected with a light guide, the right side of the PCB is provided with a yellow light-transmitting plate,and the transmission end of the right side of the yellow light-transmitting plate is electrically connected with an electromagnetic valve; and the connecting end of the electromagnetic valve is fixedly connected with an electromagnetic valve motor, the access end of the middle of the surface of the top of the electromagnetic valve motor is electrically connected with a vehicle body signal input line. A yellow light effect is achieved by reducing yellow light LEDs and controlling stretching and retracting of a light-transmitting plate through the electromagnetic valve, the cost is reduced, thearea of a light guide is effectively utilized, an optical effect is greatly utilized, a heat dissipation area is reduced, and a heat risk is decreased.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a car light color changing device and method. Background technique [0002] For existing vehicle lights, white and yellow LEDs are arranged on the same light board, and directly pass through the light guide. When turning is required, the vehicle body outputs a signal, and only the yellow LED is lit to realize turning. When day travel / position is required , the body output signal, only control the white light LED to light up to realize the day trip / position. [0003] The existing technical solution requires the use of two or more LEDs of different colors, and the cost is relatively high. The two LEDs are arranged on the same light board, which requires more heat dissipation area of ​​the light board, and the heat risk is higher. The size of the light input light port is limited. , the arrangement of the number of LEDs is limited, and the light loss is relatively high. Conten...
