Detailed ways

As shown in Figure 1, the utility model discloses a self-induction color-changing LED lamp for automobile front lighting, including a self-induction probe 1, a central controller 2, and an automobile lamp 4. In the optical module group, the self-sensing probe 1 is connected to the input end of the central controller 2, the self-sensing probe 1 is used to detect environmental visibility change information, and the self-sensing probe 1 sends a signal to the central control 2; the output terminal of the central controller 2 is connected to the LED dimming module, and the central controller 2 controls the luminous color temperature of the LED dimming module according to the received signal category.

The automobile lamp 4 includes an insulating and light-transmitting automobile lamp housing, and the LED dimming module and the self-induction probe 1 are installed in the automobile lamp housing.

The self-induction color-changing LED lamp also includes a power supply 5, which is respectively connected to the self-induction probe 1 and the central controller 2 for power supply.

The self-induction color-changing LED lamp also includes a car display screen 3, which is connected to the output end of the central controller 2, and the user can know the working status of the current LED dimming module through the car display screen 3, such as The LED dimming module is emitting white light or warm light.

As shown in Figure 2, as an embodiment of the present utility model, the LED dimming module is a three-primary-color LED dimming module, and the three-primary-color LED dimming module includes a base 10, a packaging glue 6, red, green , blue three primary color LED groups 7, 8, 9, the red, green, blue three primary color LED groups 7, 8, 9 are installed on the base 10, the encapsulation glue 6 covers the said base 10 Red, green and blue three primary color LED groups 7, 8, 9.
