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 1700lm 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 .
