1、民用建筑标准Civil building Illumination standards：
民用建筑照度标准所规定的照度，指工作面上的平均维护照度。若设计未加指明时，以距地面0.75m的参考水平面为工作面。在民用建筑照明设计中，应充分考虑建筑性质、建筑规模、等级标准、功能要求、使用条件。The illuminance specified in the standard of illumination for civil buildings refers to the average maintenance illuminance on the work surface. If the design is not specified, the reference surface is 0.75m from the ground as the working surface. In the lighting design of civil buildings, the nature of the building, the scale of the building, the grade standards, the functional requirements, and the conditions of use should be fully considered.
2、 城市道路标准City Road Illumination Standard：
城市道路照明照度标准依据以道路的级别而定，对于一二级道路，严禁采用非截光型灯具。若是水泥混凝土路面，其平均照度值可相对沥青/干燥路面降低20~30%。The standard of urban road lighting illumination is based on the level of the road. For the first and second grade roads, non-cut-off lamps are strictly prohibited. For cement concrete pavements, the average illuminance can be reduced by 20-30% relative to asphalt/dry pavement.
3、工业企业标准Industry Illumination standard：
工业企业标准照度应为生产场所作业面上的平均照度值。当眼睛至识别对象的距离大于500mm时，或需要长时间作业，或视觉作业对操作安全有特殊要求，或作业精度高等时，应采用照度范围的高值。The standard illuminance of an industrial enterprise shall be the average illuminance value at the production site. When the distance from the eye to the object to be identified is greater than 500 mm, or when it takes a long time to operate, or if the visual job has special requirements on the operation safety, or the operation accuracy is high, the high value of the illuminance range should be used.
