主题摘要
$ k3 H# ^0 a& i: o# F3 zThis is the third issue of the Outline of Investigation for Light Emitting Diode (LED) Light Sources For Use In Lighting Products. The outline covers the component parts of a light emitting diode (LED) light source such as LED modules, LED Arrays, power sources and control circuitry. It covers LED light sources that are produced by the end use product manufacturer, and that are an integral part of the end use product, or discrete component parts of an LED light source produced by one manufacturer for use in another manufacturer’s lighting product.0 [5 W8 f4 P+ U3 f! }) ^
这是第三版次的指导大纲，用来调查研究用于照明产品的LED光源。这个指导纲要涵盖了LED光源的零部件，诸如LED模块，LED阵列，电源和控制电路。它还涵盖了成品工厂所生产的，和成品成一个整体的LED光源，或者是一家工厂生产的，用于另一家工厂生产的成品之中的LED光源分立元件。
