用计算机控制的WDG-2型凹面光栅单色仪测量了四种不同配比的黄色照明剂的相对光谱功率分布曲线,由相应的软件程序一次获得其色坐标、色温(或相关色温)和显色指数的实验数据。对实验结果的分析表明,在清油和石墨粉含量不变的情况下,照明剂的色度学特性随镁粉和硝酸钠的配比而变化,这一变化主要是由于不同配比的照明剂的相对光谱功率发生了较大变化所致。
The relative spectral power distribution curves of four kinds of yellow illuminants with different proportions were measured by a computer-controlled WDG-2 concave grating monochromator. The color coordinates, color temperature (or correlated color temperature) and the color temperature Color Index experimental data. The analysis of the experimental results shows that under the condition of the unchanged content of edible oil and graphite powder, the colorimetric properties of the coating agent vary with the ratio of magnesium powder and sodium nitrate. The change is mainly due to the different proportion of the coating agent The relative spectral power has changed a lot.
