| 摘 要： | 由于LED的光比较微弱、体积小,所以在用常规的方法进行测试和使用较大的传感器时,容易产生较大的误差。为此,利用图像数字化处理技术及相应的装置对LED的配光曲线和光通量进行了测试,并介绍了它的基本原理和方法。

| Abstract: | Because LED is very small and the light emitted by it is too weak, it is very difficult to get the accurate optical parameter with common measuring method using a big sensor which will make a great difference. A digital image processing method to measure the luminous intensity distribution curve and the luminous flux of LED and equipments used in the method are introduced |

| Keywords: | light emitting diode (LED) digital camera luminous intensity distribution curve luminous flux digital image |
