针对LED的产品多样性,设计了一种可调节夹具以适应各种芯片类型的快速LED光色参数测试系统。为了提高主波长的测量准确性和快速性,提出了一种分区查表法来通过色坐标计算主波长,经实验验证,提出的快速LED光色测试系统可以提高LED测试的效率和精度。 Aiming at the LED product diversity, a fast LED light color parameter testing system with adjustable fixture to suit various chip types was designed. In order to improve the measurement accuracy and rapidity of the main wavelength, a method of subarea look-up table is proposed to calculate the dominant wavelength by color coordinates. The experimental results show that the proposed rapid LED light color test system can improve the efficiency and accuracy of the LED test.
