摘要
超高亮度LED调光功率稳定控制系统应用于显微镜的视场照明,以M CU为核心,实时对LED的亮度进行检测,根据设定的亮度等级和参考LED亮度值,控制MOS开关输出的相应PWM,使得超高亮度LED的发光稳定在特定的值。
Ultra bright LED power stabilization controlling system is used as the field illuminator of the microscope. Use MCU as the main processor, detect the LED illuminace in real time, and then control the MOS switcher to output relevant PWM based on the re-setted illuminance level and the referenced LED illuminance value, to make the voltage drop of the ultra bright LED stay in specific value.
