摘要

利用具有發熱量低、省電、壽命長、反應速度快、體積小及可平面封裝等優點之發光二極體作為光源，已成為現代照明之發展趨勢。現今白光發光二極體用於商品化的發光效率已達到40lm/W以上，已經可與目前發光效率60lm/W的白熾燈泡逐鹿市場。且白光發光二極體依然在蓬勃發展中，不斷地研發進步，最近學術界更有作出接近100lm/W之記錄。相信不久的將來，特性穩定、可靠度高之100lm/W的白光發光二極體將會大量商品化，並且取代目前市面上的白熾燈泡及日光燈，成為市場上照明光源的主流。本文將對高功率、白光發光二極體的技術原理、製作方式與市場作摘要性介紹。

With the merits of low thermal problem, power reduction, long life time, quick response characteristic, compact size and flat panel package, light emitting diode (LED) plays an important role in modern lighting industry. Nowadays, the 40 lm/W lighting efficiency for white LED lags behind that of a commercial incandescent lamp of 60 lm/W lighting efficiency. Nevertheless, the 100 lm/W lighting efficiency has been demonstrated by some laboratories recently. White LED is believed to dominate the lighting market when it achieves a target value of 100 lm/W lighting efficiency with high reliability in the near future. In this article, we will summary our point-of-views in scientific principle, devices fabrication and market status of high-power, white light LED.
