After using such scheme, the power supply of car light is used PWM to control by the present invention, utilizes illuminance transducer to feel in real time
Survey ambient light illumination, when environment is dark, the luminosity of car light is increased, and when environment is brighter, then reduces the luminescence of car light
Brightness, the use making car light is more flexible, and travel safety is more preferably.
Detailed description of the invention
Below with reference to specific embodiment, technical scheme is described in detail.
The present invention provides a kind of car light of electrocar regulation system, and for being adjusted the brightness of car light, car light uses white
Light LED；Described regulation system includes PWM controller, illuminance transducer and power supply, introduces separately below.
Illuminance transducer is located on the handlebar of electric motor car, for sensing the illumination data of surrounding, and by illumination number
According to sending into controller, the illumination on a surface irradiated by light is defined as the luminous flux being radiated in unit are, i.e. institute
The ratio that the luminous flux obtained is long-pending with face to be illuminated.
Power supply is operated with manual switches with car light and is connected, for powering for car light.
PWM (pulsewidth modulation) controller refers to be controlled analog circuit with the numeral output of microprocessor, is one
Plant and analog signal level is carried out digitally coded method.PWM controller is connected with power supply, according to the photograph of illuminance transducer sensing
Degrees of data output pwm signal, the output voltage of regulation power supply, thus regulate the luminosity of car light.
In the present embodiment, when ambient light illumination is higher, the output voltage of PWM controller regulation power supply diminishes, car light merit
