| 中文摘要: |
| 研究了光谱扫描间隔对节能照明光源色度测试及合格性判断的影响。实验采用积分球--光谱仪测试系统，分别以1nm和5nm两种光谱扫描间隔测量节能灯样品光谱、色温、显色指数、色坐标等参数。实验结果发现：1nm、5nm采样条件下光源光谱功率在610nm附近峰值相差最为显著；1nm扫描间隔所测色温值均高于5nm间隔所测值，显色指数均低于5nm扫描间隔所测值，色温和显指最大相差分别为41K和0.5。研究认为光谱扫描间隔对光源色参数测试存在一定的影响，并据此提出节能照明光源测试的优化方案。 |

| The impact of spectral scan intervals on the chromaticity measurement and the quality analysis of energy-saving lamps has been researched. An integrating sphere and spectrometer system with the spectral scan interval of 1nm and 5nm was employed to measure the spectrum, color temperatures, rendering indexes and chromaticity coordinates of light sources relatively. Results show that the spectrum differs significantly at the peak near 610nm with the measuring condition of 1nm and 5nm scan intervals, all the color temperatures measured by 1nm spectral scan interval are larger than that of 5nm, while all the rendering indexes are smaller. The ΔTc-max is 41K and ΔRa-max is 0.5.An optimal method of measuring the color of light sources is proposed based on this research. |
