当今社会,绿色、环保的概念被广泛接受,在照明领域,LED充当了这样的角色.LED灯珠具有高光效、长寿命的特点,固态封装使其不会产生汞等重金属污染.从技术发展的角度讲,LED照明终将替代传统照明,成为各行业广泛使用的照明方式.想充分发挥LED灯珠的长寿命的优点,需要设计可靠的LED照明系统.LED系统可靠性由灯珠、驱动、铝基板三部分共同决定.研发工作者对灯珠和电源的认知很深刻,但往往忽略对铝基板设计的重要性.该文介绍灯珠、驱动特性的同时,重点分析几种铝基板设计方式的差异,并提出一个良好的电流控制电路来做反馈,使系统性能更加可靠.

In today's society, green, environmentally friendly concept has been widely accepted. in the lighting field, LED act as such a role. LED lamp beads with high luminous efficiency, long life, solid package that it does not produce mercury and other heavy metals. Speaking from the perspective of technology development, LED lighting will eventually replace traditional lighting, lighting the way to become widely used in various industries.If want to give full play to long-life LED lamp beads,you need to de-sign the reliable LED lighting system. LED system's reliability is determined by three parts:lamp beads, drive, aluminum plate. Research and development worker awareness lamp beads and power is very profound, but often overlook the importance of the alu-minum plate design. This article describes the lamp beads, driving characteristics, while focusing on the analysis of several differ-ences in the way the aluminum plate design, and made a good current feedback control circuit to do to make the system more reli-able.
