Little knowledge | illumination which mainly contains the quality and quantity of the indicators? - China lighting network

In the lighting design, we should fully consider and properly handle the following lighting quantity and quality index of the intensity of illumination, brightness distribution, intensity of illumination uniformity, glare and light color, etc. Illumination shall, in light environment, make the person ought to tell him of the work details, while eliminating or adapt to control those factors can cause visual discomfort. Need to maintain the intensity of illumination of all kinds of room or place value, should comply with the provisions of the lighting design standards. Luminance distribution on the surface of object in the working environment of brightness distribution is a supplement to the lighting design, is one of the important factors in decision object visibility. Vision is suitable brightness distribution is the necessary condition to comfortable vision. In the work environment, the brightness of the observed objects if adjacent brightness environment for it three times, better visual clarity. Intensity of illumination evenness of indoor lighting illumination uniformity with a given minimum illuminance on the working plane and the ratio of the average illuminance, usually require to 0. 7 - 0. 8. The intensity of illumination evenness of rooms or rooms should comply with the provisions of the lighting set standards. Direct glare restrictions on general lighting glare restrictions should be light brightness, light apparent size, background luminance factor and the position of the installation of lamps and lanterns, etc. Reflected glare restrictions generally want to use the visual object does not work in nor any lighting light source with eyes close to the mirror in the Angle of reflection. Light color chosen light should be suitable to the functional requirements and place, should be comfortable color table and good color rendering. YanZhiXiang
