All 2,800 Classrooms in Gongshu District, Hangzhou Are Equipped With Eye Protection Lights

School is around the corner, the renovation and upgrading of eye protection lights in 2,800 classrooms in Gongshu primary and secondary schools and kindergartens in Hangzhou has been completed. The "Bright Eyes and Eye Care" campaign was "delivered" as scheduled, and a big gift was sent to the children for the beginning of the school year.

Intelligent switching of light application scenarios, Let children learn happily in comfortable lighting

After a summer vacation renovation, the lighting renovation of Hangzhou Yucai Dengyun Primary School has taken on a new look. The 9 lights and 3 blackboard lights in the classroom are evenly distributed. These are newly installed LED professional eye protection lights, which can effectively avoid flicker, glare, blue light, etc.

On the wall at the entrance, there is an additional control panel next to the ordinary switch, which distributes 6 buttons of "class, projection, after-school, self-study, recess, and exam", corresponding to 6 different application scenarios.

Zhang Weiqi, deputy director of the Gongshu District Education Development Service Center, introduced that when you press the class button, the lights in the entire classroom will light up; when you press the projection button, the two blackboard lights which close to the projector will automatically go out, and the rest of the lights will not be affected. These function module button are like shortcut keys, which can call up the light intensity that is most suitable for children's vision with one button.

One-button dimming is not only convenient, but more importantly, it ensures even distribution of light. The national standard for classroom lighting is 300lux for desks and 500lux for blackboards. The distribution of each light in the classroom, the position where the long axis of the light is perpendicular to the blackboard, and the height from the desk are the results of precise calculation of big data. "We install eye protection lights in each classroom. We must first measure its length, width and height, and use computer modeling to determine the installation point. This includes lights by the window under different light conditions, such as sunny and cloudy days. The brightness of the light in the middle of the classroom is also adjusted according to the situation. There is a light sensor on the light, which can realize real-time update and transmission of data, ensure that the illumination in the classroom always meets the national standard, and protect children's eyesight." Zhang Weiqi said.
