It is possible to reduce the error rate by increasing the illumination level, and in areas where errors are likely to persist,
higher illumination levels are recommended.
Higher illuminance and color rendering light sources are recommended for areas that are prone to errors due to the high speeds of the production process and nearby areas.
In the work area without windows or natural light, low illumination tends to make people depressed, in order to make the staff feel comfortable and happy, it is recommended to use a higher illumination and high color temperature light source. (Illumination should not be less than 500lux) Staff need to work at night in the area, it is recommended that the illumination is not less than 500lux.
Must consider the contrast between the work surface and the environmental brightness, good contrast of illumination, can reduce the error, reduce the fatigue level.
