What are the requirements for the illuminance of office lights?
Office decoration needs to do a good job of lighting layout. What are the office lighting standards? Today, the teaching office lamp manufacturer will answer you one by one.
The illuminance of office lights is based on the national standard "Architectural Lighting Design Standards" GB 50034-2004, the illuminance of ordinary offices is 300lx, and the illuminance of high-end offices is 500lx. In the design, the power density of the illumination design of the high-end office is 15W~18W/square meter; the power density of the illumination design of the ordinary office is 9W~11W/square meter.
1. Select the appropriate color temperature and color rendering index of the light source, generally choose >4000K color temperature in the office, and select Ra≥75 for the color rendering index.
2. Lighting level: Different environments and places have different requirements for lighting. The illuminance of the office space should meet the use requirements, generally 500-1000lx.
3. Lighting uniformity: Arrange lamps reasonably to make the illuminance uniform, so that the difference between the maximum and minimum illuminance of the office and the average illuminance is less than 1/3 of the average illuminance.
4. Comfort and glare control: When there is too high brightness or too large brightness ratio in the field of view, people will feel dazzling glare. The measures to prevent glare are mainly to limit the brightness of the light source and arrange the light source reasonably. If the light source is more than 45 degrees of the line of sight, form a shading angle or block the light source with an opaque material.
5. Safety: mainly consider the safety of the lamp structure, the safety of electrical appliances, whether the lamp meets the national standard, whether it has passed the 3C certification, etc.
6. Energy saving and environmental protection: choose high-efficiency light source, high-efficiency, long-life, reasonable light distribution lamps, high-performance, long-life accessories, etc.
