摘要

摘要: 针对LED光谱分布可调光源对LED寿命以及光谱一致性的要求，对可见光和近红外波段的29种LED分别进行200 h的电流加速老化试验，并提出LED光谱一致性筛选算法。老化试验结果表明：峰值波长为385 nm、400 nm 和4201 nm 3种LED的辐射通量平均衰减分别为24.8 %、10.7 %和25.6 %，不能用于LED光谱分布可调光源；剩余的26种LED的辐射通量平均衰减量均低于3.5 %，可作为光谱分布可调光源的内部光源。LED光谱一致性筛选算法以LED光谱数据为基础，计算同类LED间的相对光谱偏差，26种LED的相对光谱偏差均小于4.5 %，保证了所筛选出LED的光谱一致性。

Abstract: In order to meet the requirements for lifetime and spectrum consistency of LED used in LED-based spectrum-tunable light source, 29 kinds of LEDs were seasoned for 200 hours separately under the accelerated current condition, and a spectral consistency screening algorithm was proposed. Results of ageing test indicate that the values of radiant flux attenuation of 3 kinds of LEDs, whose peak wavelengths are 385 nm, 400 nm and 420-1 nm, are 24.8%, 10.7% and 25.6%,respectively, so they are not suitable for LED-based spectrum-tunable light source. The values of radiant flux attenuation of the remaining 26 kinds of LEDs are all below 3.5%, and they are all suitable for LED-based spectrum-tunable light source. The spectral consistency screening algorithm is based on the LED-s spectroscopic data, and the relative spectral deviation among the same kinds of LEDs can be calculated. The relative spectral deviations of 26 kinds of LEDs are all below 4.5%, the spectral consistency of the screened LED can be ensured.
