Time;
2
Long-term continuous high-intensity visual work has adverse effects on visual organs;
three
When it is difficult to recognize a moving object due to a short recognition time;
four
When visual work has an important impact on operational safety;
five
When the brightness contrast of the recognition object is less than 0.3;
six
When the operation accuracy is very high, the error will cause great losses;
seven
When the visual ability is lower than the normal ability;
eight
When the building grade and function requirements are high.
When one or more of the following conditions are met, the illuminance of the working face or datum plane can be reduced by one level according to the standard value of the degree.
1
When working for a short time;
2
When the accuracy or speed of operation is irrelevant;
three
When the building level and function requirements are low.
Generally, compared with the standard illuminance value, the design illuminance value may have a deviation of-10%-+ 10%.
