LED手术无影灯的关键电路设计

摘要

介绍了一种基于STC12C5A60S2型单片机为核心的控制模块和以HV9910B为核心的驱动电路组成的新型LED手术无影灯控制系统，分析了LED驱动电路的组成和MCU的控制方法。本文设计中的LED无影灯相比于传统无影灯来说功耗更低、显色性能更好、安全度更高、舒适度更好，更加符合医院手术室的功能特点。%This paper introduced a new LED astral lamp system based on the STC12C5A60S2 microcontrol er as the control module and the HV9910B as the core of the drive circuit. It mainly analyzes the structure of the LED drive circuit and the control method of MCU.This LED astral lamp has lower power consumption,higher coloration,safer performance and better comfort,so it is in line with the functional characteristics of the hospital operating room by compare with the traditional astral lamps.
