What standards should a good classroom lighting environment meet
"The book mountain has roads and diligence as the path, and the learning sea has no boundaries." Nowadays, education has become the most worrying thing in people's lives. How to provide a good classroom lighting and learning environment? According to Benwei Lighting's different school classrooms From the experience of lighting renovation, most of the classroom lighting has low average illuminance, low illuminance, high glare value, and serious light decay of the desks and blackboards in the classroom...
The State Administration for Market Regulation and the National Standardization Administration approved and issued the "Hygiene Requirements for the Lighting Design and Installation of General Classrooms in Primary and Secondary Schools" (GB/T36876-2018). The sanitary requirements for installation have been specified in detail:
1) Hygienic requirements for illuminance of classroom desktops and blackboards
Maintain the average illuminance not less than 300lx and the uniformity of illuminance not less than 0.7; maintain the average illuminance not less than 500lx and the uniformity of illuminance not less than 0.8 on the blackboard surface.
2) Hygienic requirements for design and installation of classroom lighting
It is advisable to use hanging grid lamps, and the lamp efficiency should not be less than 60%; the unified glare value (UGR) should not be greater than 19; the color temperature should be 3300K-5500K, and the color rendering index should not be less than 80.
The led eye-protecting classroom lights and led eye-protecting blackboard lights developed and produced by Benwei Lighting are the latest technology products developed on the basis of traditional grille lights and constantly accumulating research and development. Its glare (UGR) is less than 16, the color temperature is 5000K, the color rendering index is greater than 90, and there is no blue light hazard. It is an upgraded product of the latest generation of classroom lights.
3) It is advisable to use a boom installation method, and evenly arrange the classroom lighting power density according to the longitudinal direction of the classroom (the long axis of the lamp is perpendicular to the blackboard). The vertical distance (g) between the lamp and the desk is not less than 1700mm.
Benwei Lighting has designed lighting fixtures specially designed for classrooms, which conform to the national standard. The desks maintain an average (constant) illuminance greater than 300lx and an illuminance uniformity of 0.7; the blackboard maintains an average (constant) illuminance of 500lx and an illuminance uniformity of 0.8; and the color rendering index is greater than 90. High color reproducibility; adopts grille anti-glare design, glare value is less than 16, not dazzling; color temperature is 5000K, comfortable and soft; the entire classroom has uniform illumination and no flicker!
