Embodiment Construction
[0017] The technical solutions of the present invention will be described in detail below in conjunction with specific embodiments.
[0018] The invention provides a method for adjusting the brightness of an electric vehicle lamp, which is used for adjusting the brightness of the lamp. The lamp adopts a white LED; an illuminance sensor is arranged on the handlebar of the electric vehicle, and PWM is output according to the illuminance data sensed by the illuminance sensor. Signal, adjust the output voltage of the power supply, thereby adjusting the brightness of the lights.
[0019] In order to realize the above regulation method, PWM controller, illuminance sensor and power supply can be used, which will be introduced separately below.
[0020] The illuminance sensor is set on the handlebar of the electric vehicle to sense the illuminance data of the surrounding environment and send the illuminance data to the controller. The illuminance on a surface illuminated by light is d...
