发光效率乃是光源产品的最重要特性之一。白光LED或其灯具设备系统的效率,通常以发光效率(Luminous efficacy;Lumens per watt;LPW;lm/W)来说明。 根据美国于2007年9月所公布有关固态光源灯具设备的“能源之星(ENERGY STAR®)”规范,其中A类要求(Near-term applications)系根据不同的灯具设备及应用(如室内或户外)所...
An LED lamp according to some embodiments of the invention has an efficiency of at least about 150 lumens per watt. In some embodiments, the lamp has a light output of at least 1200 lumens. In some embodiments, the LED lamp produces light with a color rendering index (CRI) of at least...
In the case of LED lighting, lumens are the unit of measurement of the brightness of the light. The concept of lumens is different from watts. While watt measures the amount of energy consumption, lumens measure the brightness of the light.
When it comes to lighting, efficiency is defined as the light output per unit power. Thus, in the metric system, it is measured in lumens (lm) per watt (W). Recently some LED manufactures introduced LEDs with promised efficiencies hitting the 150 lm/W mark. In comparison, incandescent ...
