摘　　要：通过实验,研究了用光纤光谱仪测量发光二极管色度的方法。该方法先用标准光源对光纤光谱仪进行波长和强度校正,然后结合积分球测出发光二极管的光谱功率分布,最后根据色度学原理计算出发光二极管的色度坐标。实验表明,用光纤光谱仪测量发光二极管的色度特性的方法简单快捷,测量结果准确。The experimental method to measure the chromaticity of LED with the fiber spectrometer is dis- cussed. The wavelength and intensity correction to the fiber spectrometer are taken using the standard light source at first. Then, the spectral power distribution of LED is detected with an integrating sphere. Finally, the LED＇s chromaticity coordinates are calculated according to the chromaticity theory. The results show that the method of measuring LED chromaticity with the fiber spectrometer is simple and accurate.
