Lighting methods can be divided into: general lighting, district general lighting, local lighting and hybrid lighting. The applicable principles should meet the following requirements:
1. When it is not suitable to install local lighting or use mixed lighting, it is reasonable to use general lighting;
2. When a certain work area needs to be higher than the general illumination, partitioned general illumination can be used;
Third, for the illumination requirements are higher, the work position density is not large, and the installation of general lighting is not reasonable, it is appropriate to use mixed lighting;
4. Local lighting should not be installed in a workplace.
