As a necessary lighting source for school classrooms, what national standards should classroom lighting meet?

The State Administration of market supervision and the State Standardization Administration approved and issued the hygienic requirements for lighting design and installation of ordinary classrooms in primary and secondary schools (GB / t36876-2018). In this new standard, the specific parameters, overall illumination and hygienic requirements for design and installation of lamps in primary and secondary schools are specified in detail:

1. Suspended grid lamps should be used, and the efficiency of lamps should not be less than 60%.

2. The uniform light value (UGR) of lamps shall not be greater than 19, and the calculation method of uniform glare value (UGR) shall be implemented according to cie117.

3. The color temperature of lamps shall be 3300K ~ 5500k, and the color rendering index shall not be less than 80.

4. The average illumination of the classroom desktop shall not be less than 300lx, and the illumination uniformity shall not be less than 0.7; The average illuminance on the blackboard surface shall not be less than 500lx, and the illuminance uniformity shall not be less than 0.8.

5. The lamps shall be installed with suspenders and evenly arranged according to the longitudinal direction of the classroom (the long axis of the lamps is perpendicular to the blackboard). The lighting power density of the classroom shall not be higher than 11W / ㎡, and it should be lower than 9W / ㎡ in conditional areas. The vertical distance (g) from the lamps to the desk shall not be less than 1700mm.

6. When calculating illuminance in lighting design, its maintenance coefficient shall be 0.8.
