Problems solved by technology
[0002] The brightness of the daytime running lights of cars we see on the road today is fixed, some are too bright, some are too dark, and cannot adapt to the external environment well
When the outside light is too strong, the brightness of the daytime running lights will not be obvious no matter how strong it is, and it will waste electricity; on the contrary, when the outside light is weak, if the brightness of the daytime running lights is not enough, it will bring safety hazards

Embodiment Construction
[0013] The present invention will be further explained below in conjunction with specific embodiments and drawings.
[0014] Such as figure 1 As shown, a daytime running light with automatic brightness adjustment function includes an LED lamp group 2, a circuit board 1, a photoresistor 3, and an LED control module 4. The LED lamp group 2 is installed on the circuit board 1, so The circuit board 1 is connected to the LED control module 4, and the photoresistor 3 is connected between the circuit board 1 and the LED control module 4.
[0015] Among them, the LED control module 4 specifically includes a light control sub-module and a driving sub-module. The light control submodule is used to collect the instantaneous resistance value of the photoresistor 3, and output a corresponding light intensity signal to the driving submodule according to the collected instantaneous resistance value. The driving sub-module controls the light intensity of the LED lamp group 2 according to the rece...

The invention relates to a daytime running lamp having an automatic brightness adjusting function and belongs to the field of vehicle lamps. The daytime running lamp having the automatic brightness adjusting function is characterized by comprising an LED lamp group, a circuit board, a light dependent resistor and an LED control module, wherein the LED lamp group is installed on the circuit board, the circuit board is connected with the LED control module, and the light dependent resistor is connected between the circuit board and the LED control module. The brightness of the lamp can change with the light intensity in the outside under the situation that a daytime running lamp structure is not changed, the daytime running lamp well adapts to the environment, energy is saved, emission is reduced, and potential safety hazards are eliminated.
Description
Technical field [0001] The invention relates to the field of vehicle lights, in particular to a daytime running light with the function of automatically adjusting brightness. Background technique [0002] The brightness of the daytime running lights of the cars we see on the highway today is fixed, some are too bright, some are too dark, and cannot adapt well to the external environment. When the outside light is too strong, the brightness of the daytime running lights is not obvious, and wastes electricity; on the contrary, when the outside light is weak, if the brightness of the daytime running lights is not enough, it will bring safety risks. Summary of the invention [0003] The purpose of the present invention is to solve the above problems and provide a daytime running light with automatic brightness adjustment function, so that the brightness of the daytime running light can change with the intensity of external light, better adapt to the environment, and save energy. Redu...
