Abstract (AI)
High-power light-emitting diodes (LEDs) have begun to differentiate themselves from their more common cousins the indicator LED. Today these LEDs are designed to generate 10-100 lm per LED with efficiencies that surpass incandescent and halogen bulbs. After a summary of the motivation for the development of the high-power LED and a look at the future markets, we describe the current state of high-power LED technology and the challenges that lay ahead for development of a true "solid state lamp." We demonstrate record performance and reliability for high-power colored and white LEDs and show results from the worlds first 100-plus lumen white LED lamp, the solid state equivalent of Thomas Edison's 20-W incandescent lightbulb approximately one century later.
Key Findings
1
High-power LEDs generate 10–100 lumens per device and achieve efficiencies exceeding incandescent and halogen bulbs.
2
Record performance and reliability are demonstrated for both colored and white high-power LEDs.
3
The authors report the world’s first white LED lamp exceeding 100 lumens, equivalent to approximately a 20-W incandescent bulb.
4
The paper reviews high-power LED technology, prospective markets, and the remaining challenges to developing a true solid-state lamp.
5
The results indicate that solid-state lighting can provide a practical alternative to conventional incandescent and halogen illumination.
