Flood lighting light
Generally speaking, the light colors used in architectural nightscape lighting can be divided into white light and colored light. White light includes cool white light of about 6000k (such as the light emitted by daylight-colored fluorescent lamps and high-pressure mercury lamps), and warm light of about 4000k. White light (such as the light emitted by metal halide lamps), and 2000~3000k warm yellow light (such as the light emitted by incandescent high-pressure sodium lamps, etc.). Colored gloss includes those obtained by using colored light sources or color filters. Colored lights in various hues.
Since the light colors of various light sources are different, when colored light is required, color filters are generally used, and the light that causes perspective will be greatly reduced. The color transmittance ratio is: amber color filter 0.4~0.6, red filter light 0.15~0.2 , green color filter 0.05~0.1, blue color filter 0.03~0.05, taking into account the absorption effect of the color filter, in order to obtain the same illumination as colorless light or the same decorative effect, the light source illumination must be increased accordingly.
