发光二极管照明英语:LED lamp)是指利用发光二极管作为光源的技术,大致可分为半导体发光二极管及有机发光半导体(OLED)两种主要类别。目前用在照明上的主要是半导体发光二极管,但使用高分子发光二极管(PLED,属 OLED的一种)作为照明光源的研究,也正在进行中。

单颗发光二极管的光度比传统灯泡和省电灯泡低很多,所以一个灯泡通常会包含多颗发光二极管。近年,二极管技术提高,高功率、高光度的发光二极管陆续上市,使得这类灯泡渐有取代其他传统光源之势。已有厂商推出单颗设计的照明用高功率LED芯片,只需100瓦的电力,就能发出7,527流明的光度。。除了用于专为LED所设计的灯具外,LED也可在加装转换电路与相关的稳定设备后,制成与其他光源兼容的灯泡,安装于传统光源的灯具中。

LED lamp 发光二极管照明

(重定向自LED bulb)
A 230-volt LED filament light bulb, with a E27 base. The filament is visible as the eight yellow vertical lines.
An assortment of LED lamps commercially available as of 2010 as replacements for screw-in bulbs, including floodlight fixtures (left), reading light (center), household lamps (center right and bottom), and low-power accent light (right) applications

LED light bulb to replace G24 compact fluorescent lamp

An LED lamp is a light-emitting diode (LED) product which is assembled into a lamp (or light bulb) for use in lighting fixtures. LED lamps have a lifespan and electrical efficiency which are several times longer than incandescent lamps, and significantly more efficient than most fluorescent lamps, with some chips able to emit more than 300 lumens per watt (as claimed by Cree and some other LED manufacturers). The LED lamp market is projected to grow by more than twelve-fold over the next decade, from $2 billion in the beginning of 2014 to $25 billion in 2023, a compound annual growth rate (CAGR) of 25%.
