The relationship between measured light flux and LED position mode is shown in Figure 4 and Figure 5. The results show that even in the most extreme cases, when leds are placed before and after the detector opening, the peak luminous flux results are less than 5%. This is a very good test result. In the actual testing process, the repeated error of LED light flux measurement is far less than 0.1%. It can be seen that the test results of LPCE-2 test system are reliable and stable, which can provide a reliable guarantee. This standard system not only greatly supports LED research and development and production, but also is an ideal choice for optical performance measurement in the LED industry.
