摘要

多LED组合型光源在灯具设计中应用日益广泛。多LED组合型光源既可以通过把多颗LED芯片直接封装在一个单体内

也可以把多颗封装好的单芯片LED光源在PCB设计时进行组合

两种实现途径决定了LED光源在尺寸、传热性能、可维护性等方面存在较大差异。LED串并联方式直接影响各LED支路的电流均衡性

为了确保各LED串联支路电流一致

文章给出了驱动设计中常用的几种方案。除此之外

还给出了利用普通环氧PCB板进行传热设计的解决方案

达到了与铝基PCB板相同的传热效果。

Abstract

Lamps based on multi-LED combined have being used more and more widely. Such lamps can be manufactured not only by packaging multi-LED in one unit

but also by distributing many packaged LED individual lamps on print circuit board(PCB) directly. The two approaches decide the difference in lamp structure

heat transmission capability

maintenance

and so on. The connection methods of LEDs affect directly the current balance between different LED serials. Several different driver designs are discussed in this paper in order to insure the consistency of different LED serials. Furthermore

one kind of heat transmission scheme based on epoxy print circuit board has experimented

which can achieve the same effect as PCB based on aluminium.
