With the development of technology, stage lighting equipment is also constantly upgrading, especially the moving head lamp which is a kind of multi-functional and high-performance lighting equipment. The old version of stage moving head lamp has insufficient illuminance, large color temperature difference between light sources, and the brightness of light source is dark or too high, and the color is also dark or deep, so the effect of stage equipment cannot meet the customer's usage requirements. Therefore, the new version of moving head lamp light source requires strict requirements, and the color temperature difference of the light source should be small to ensure the harmony and unity of the light effect of the whole stage and avoid poor visual effect caused by inconsistent color temperature. In order to ensure that the performers or exhibits on the stage can be adequately illuminated, the new version of moving head lamp needs to provide higher illuminance, and the brightness of light cannot be too dark or too high, and the uniformity and moderation of brightness need to be considered in design to avoid visual fatigue or discomfort of the audience.

[0003] When detecting the light source, the light source needs to be lit within a range of 5M, and a handheld illuminance meter and a spectrometer are used for detection.
