LED (Light Emitting Diode,发光二极管) LED是光源技术中最为基础的缩写,指的是发光二极管。它是一种将电能转换为光能的半导体器件,具有高效、节能、长寿命等优点。 LUM (Lumen,流明) LUM是光通量的单位,表示光源在单位时间内发出的总光量。流明是评估LED光源亮度的常用指标。 LUX (Lux,勒克斯) LUX是照度的单位...
4 modes of color temperature of radiation were tested: in the 1st group-in all periods of light 3000 K; in the 2nd group-the first and last periods of light 3000 K, the average period of light 5000 K; in the 3rd group-the first and last periods of light 5000 K, the average ...
white LEDs, the correlated color temperature (CCT) changes. It's difficult for the human eye to detect a change of a few nanometers in a red, green, or blue LED, especially when the light intensity is also changing. A change in color temperature of white light, however, is easily ...
针对LED照明产品在颜色方面测量的要求,国内外各大标准起草者和协会已对LED的色度、相关色温(Correlated Color Temperature;CCT)、显色指数(Color Rendering Index;CRI)等要求增补入列。如美国国家标准照明组提出的《固态照明产品的色度指标》被作为能源之星项目评估灯具光色的重要参考,日本致力LED研究的几个团体最早也提出...
