Color rendering
1. Classification: According to the CIE standard and GB50034-92, the color classification is listed in Table 1.
Examples of adaptation sites in Table 1 are written in accordance with GB50034-92 and GBJ133-90. The newly developed and published CIE standard - "Indoor Workplace Lighting" (CIE S008/E-2001), has improved color rendering requirements in many places, such as offices, control rooms, etc. are listed in the IB category.
2. Application: The value of Ra is of great significance for establishing a good lighting environment in modern construction sites. It is not only the need to identify the color of the recognition object, but also has a great influence on the visual effect and visual comfort. The color rendering index of the light source is high, and the image of the object and the person to be seen will appear more realistic and vivid; on the contrary, it will become unsightly and lose its original luxury and luster.
At present, in the lighting engineering design, the color rendering index of the light source is not enough, the visual effect is lowered, and it is hoped to pay more attention. In the design, the color rendering index requirement, that is, the color rendering category, should be determined for each place and room, and the light source that meets the color development requirements should be selected according to this standard.
Color table of light source
1. Classification: According to CIE and GB133-90, GB50034-92, the color table of the light source is divided into three categories according to the correlated color temperature.
2. Application: According to the use characteristics of the place, the level of illumination and the atmosphere to be created, choose the appropriate color source color table category. Generally speaking, the lower illumination (150~200Lx or less) place needs a warm and friendly atmosphere. Use warm color table; high illumination concept (750Lx or above) or tropical area, hot processing workshop, etc. should use cold color table; and most places should use intermediate color temperature.
The main problem at present is that some designs do not specify the color temperature of the light source, which is freely purchased by the contractor and does not achieve the best results. In addition, there are too many cold color fluorescent tubes, and some even think that the higher the color temperature, the brighter the misunderstanding, resulting in The location does not match, and it also affects the improvement of light efficiency.
Some high-grade public buildings often use light colors to adjust or create a variety of moods, creating a variety of different atmospheres, such as warm or quiet, nervous or brisk.
