一、混光照明的发展现代照明对照度、光源颜色和显色性能都提出了较高的要求,同时还要考虑照明节能、减少费用等。但是,在采用单独一种光源时往往得不到上述效果,如单独使用荧光高压汞灯,光色青紫,气氛阴沉;单独使用高压钠灯时,光色太黄,环境物体颜色失真,周围像是涂上一层黄色,很不舒服。因此,出现了使用两种以上光源共同照明的方式,称为混光照明。
First, the development of mixed lighting The modern lighting contrast, light source color and color rendering performance have put forward higher requirements, but also consider lighting energy, reduce costs and so on. However, these effects are often not obtained when a single light source is used. For example, a fluorescent high-pressure mercury lamp is used alone, the light color is cyan, and the atmosphere is gloomy; when the high-pressure sodium lamp is used alone, the light color is too yellow, and the color of the environmental object is distorted. It is very uncomfortable to apply a layer of yellow. Therefore, there has been a way of using two or more light sources to co-illuminate, known as mixed light illumination.
