在照明系统中应用调光首先要满足视觉环境对照度的基本要求,为人们提供方便、舒适的照明环境。良好的室内照明并不是单纯追求充足的光亮,必须要满足一定的照明质量要求。照明质量主要是指照度均匀性、照度稳定性和频闪效应的影响四个方面的内容。在保证照明质量的前提下,在照明控制系统中运用调光可以有效避免电能浪费、提高能效。照明质量的具体要求如下:1)照度均匀性。室内照明要求灯具照到被照面上光的强弱要均匀,一般要求照度均匀度在0.7以上。
Dimming in the lighting system should first meet the basic requirements of the visual environment contrast for people to provide convenient and comfortable lighting environment. Good indoor lighting is not simply the pursuit of adequate light, must meet certain lighting quality requirements. Lighting quality mainly refers to the illumination uniformity, illumination stability and strobe effect of four aspects. In ensuring the quality of lighting under the premise of the lighting control system using dimming can effectively avoid waste of energy and improve energy efficiency. The specific requirements of lighting quality are as follows: 1) Uniform illumination. Interior lighting requirements according to the illumination of the plane according to the intensity of light should be uniform, the average illumination uniformity requirements of 0.7 or more.
