在节能技术呼声高涨的今天，LED 照明将成为照明技术的发展主流已成为共识。由于其高能效，人们普遍认为用LED灯取代传统的灯泡、荧光灯是一种非常环保的做法。
本文简要介绍LED发展现状及趋势，并在分析了LED发光原理，伏安特性以及电阻限流、线性控制、开关变换等几种大功率LED恒流驱动电路开发方案的基础上，提出了一个低成本、稳定、安全的大功率LED恒流驱动电路设计方案，并应用熔丝管、全波整流桥、三端稳压管MC7085BT和恒流二极管2DH070等元器件对所提出的LED驱动电源的电路加以实现。该电路为电路提供低消耗、过流保护等功能。
Energy-saving technologies are recognized nowaday , LED lighting will become the mainstream of the development of the technology which has become a consensus.Because of its high energy efficiency, it is generally believed that the LED will replace the traditional light bulbs, and the fluorescent lamps is a very environmentally friendly practices.
The article will briefly introduce the current situation and trend of the LED development and analysis the element. One the basis of voltage characteristics, resistance current limiting, linear control, the switching transformation of several high-power LED constant current drive circuit development programs etc. and come up with a design proposal which is low-cost, stable, secure and high-power LED constant current drive circuit. ...
