| 摘 要： | 结合LED节能环保、超长寿命的优点,采用了恒流驱动方式。以STC89C51单片机为控制核心,采用PWM技术对LED灯发光强度进行控制,通过亮度传感器采集车厢内的亮度信息,对车厢内LED照明系统进行亮度调节。仿真结果表明,系统LED发光亮度均匀,达到了设计要求。

| Abstract: | The energy-saved and long-life-span LED is driven by constant current .STC89C51 single chip is chosen as the controller and PWM technology is applied to control the light intensity .The brightness information collected by a brightness sensor is sent to the controller as the feedback for adjusting the brightness .The simulation results illustrate that the brightness of the LED luminous system is even ,which arrives at the needed indexes . |
