Illumination Requirements for Different Applications Football field night lighting standards General conditions: 100000 LUX in the summer sun, 0.1 LUX candlelight for night street lights (20cm away), 10～15 LUX in sunny days, 30000~300,000 10,000 LUX outdoors in cloudy days, 100 LUX for indoor fluorescent lamps in production workshops, 60cm from 60W desk lamps It is 300LUX, TV studio is 1000LUX, night room is 10LUX, cloudy day is 3000lux, office 30~50lux, sunrise and sunset 300lux, restaurant 10~30lux, moon circle 0.3~0.03lux, corridor 5~10lux, starlight 0.0002~0.00002 lux, parking lot 1~5lux, dark night 0.003~0.0007lux. Similarly, the area of the hemisphere with a radius of 5m is: 2π×52=157 m2, and the illuminance value at 5m from the light source is: 1200Lm/157 m2=7.64Lux. The area of the hemisphere with a radius of 1m is 2π×12=6.28 m2, and the illuminance value at 1m from the light source is: 1200Lm/6.28 m2=191Lux. The illuminance value at 5m and 5m can be obtained by the following steps: If it is assumed that the luminous flux is evenly distributed on the hemispherical surface, it is 1m away from the light source. Incandescent lamp has a total luminous flux of about 1200Lm. In order to have a perceptual understanding of the contrast, the following calculation is given as an example. The unit of illuminance is the number of lumens (Lm) per square meter, also called lux (Lux), namely: Confirm the relationship of 1Lux=1Lm/m2: 1lux=1lm/square meter=1cd×sr/square meter. Illuminance unit (lux) Illuminance is a unit that reflects the intensity of light, and its physical meaning is the luminous flux irradiated on a unit area. (Or the indoor illuminance in a cloudy sky in the table below) For an object that is uniformly illuminated by light, when the luminous flux obtained on an area of 1 square meter is 1 lumens, its illuminance is 1 lux.

If you are using a “lamp”, an ordinary 40-watt lamp can reach 3000 Lux at a distance of about 0.2 meters. It is difficult to achieve a brightness of 3000 lux, and it is usually unnecessary. The transliteration of English lux can also be written as lx. Lumen is the abbreviation of luminous flux, or Lumens.
