Understanding LED Technology

LEDs may be little, but new high-brightness models are producing a considerable amount of light.

First used as status and indicator lamps, and more recently in under-shelf illumination, accent lighting, and directional marking applications, high-brightness LEDs have emerged within the last six years. But only recently have they been seriously looked upon as a feasible option in general purpose lighting applications. Before you recommend or install this type of lighting system, you should understand the basic technology upon which these devices are based.

發光二極管 Light-emitting diode

發光二極體 (Light-emitting diode, LED) 是一種半導體元件。初時多用作為指示燈、顯示板等;隨著白光發光二極管的出現,也被用作照明。它是21世紀的新型光源,具有效率高、壽命長、不易破損等傳統光源無法與之比較的優點。加正向電壓時,發光二極體能發出單色、不連續的光,這是電致發光效應的一種。改變所採用的半導體材料的化學組成成分,可使發光二極體發出在近紫外線、可見光或紅外線的光。
