| 摘 要： | 研制了一种组合式LED模块标准光源组。LED模块标准光源组由可调节角度和长度的支臂和多颗白光LED组成，LED的芯片直接封装到热电制冷器TEC上保持光通量恒定。根据待测光源的形状和光通量，确定LED颗数并调节支臂，使组合成的LED模块与待测LED模块相仿，作为车灯LED模块积分球光通量测试的标准光源。实验结果表明，用4颗LED组成17001m的光源组，每10分钟测试一次，测试10次后的不稳定度为2．0％。组合式LED模块标准光源组光通量恒定，具有广泛的应用前景。

| Abstract: | A current modular standard LED source was developed. It is composed of the arms with adjustable angle and length and multiple white LED components which directly encapsulated into the thermoelectric cooler TEC in order to maintain a constant luminous flux. According to the shape and luminous flux of the tested LED light source, the LED number was determined, then the arms will be adjusted to be similar to the tested LED module as luminous flux testing standards with the integrating sphere. Experimental results show that the instability was 2.0% with a modular standard source 17001m consisted of 4 LED, tested 10 times every 10 minutes. The modular standard source LED module with constant luminous flux has a wide range of applications. |
