环境光线测试仪主要用于环境光线强度测试，借以发现光线强弱是否符合我们生理需要。
Environmental light testing equipment is mainly used to test intensity of ambient light. Its purpose is to find out whether intensity of the light meets our physiological needs.
由于光圈控制着进入相机的光线总量，也就是说曝光强弱可以由光圈来控制。
Since the amount of light reaching the camera is dependent on the aperture, the overall exposure is altered by changes in aperture.
因此借由红，绿，蓝三种不同强弱的光线组合后，可产生多种的颜色感觉。
Therefore, with the combinations of red, green and blue light of different intensity, we can sense different colors.
