Problems solved by technology

[0003] (1) People sometimes forget to turn off the light when they lock the electric car after using the electric car, especially when the sky is not too dark, so the car light will always be on until Being discovered or the power in the battery is exhausted, wasting power;
[0004] (2) When people suddenly enter a tunnel or other dark environment, they are not used to turning on the lights in time, or it is not convenient to turn on the lights with both hands, so that they cannot be found by the opposite or behind vehicles, which is prone to danger and poor safety.

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...

Abstract

The invention discloses an electric vehicle lamp brightness adjustment method. According to the method, an illuminance sensor is arranged on the handlebar of an electric vehicle; PWM signals are outputted according to illuminance data sensed by the illuminance sensor; and the output voltage of a power source can be adjusted, so that the light emission brightness of the lamps of the electric vehicle can be adjusted. With the method adopted, the brightness of the lamps of the electric vehicle can be automatically adjusted according to ambient brightness, and energy-saving performance and environmental friendliness can be achieved.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a method for adjusting the brightness of electric vehicle lamps. Background technique [0002] Electric vehicles are widely used because of their energy saving, environmental protection, and ease of use. In order to facilitate people to drive safely in dark environments, electric vehicles are equipped with lights, but the control of the lights is by manual switches, which exists With the following questions: [0003] (1) People sometimes forget to turn off the light when they lock the electric car after using the electric car, especially when the sky is not too dark, so the car light will always be on until Being discovered or the power in the battery is exhausted, wasting power; [0004] (2) When people suddenly enter a tunnel or other dark environment, they are not used to turning on the lights in time, or it is not convenient to turn on the lights with both hands, ...
