The background and advantages of the school classroom lighting renovation plan
According to investigations, domestic primary and secondary schools, and even many colleges and universities, still use traditional fluorescent lamps with phosphors. This kind of lamps not only wastes electricity, but also because the lamps themselves contain heavy metal substances, they will affect the health of young people. Because of the unstable voltage of the lamp, there will be frequent flicker, which has a great impact on the eyesight of young people. Therefore, the renovation of school classroom lighting is inevitable!
The current situation of school classroom lighting
At present, the classroom lamps use simple fluorescent lamp brackets, but there is no special lamp for blackboard lighting. Ordinary bracket lamps are used as blackboard lamps installed in front of the blackboard, and there is even no blackboard lighting at all. The light source of the fluorescent lamp bracket is directly exposed to the outside of the lamp, without any anti-glare measures, which has a great glare effect on the students sitting in the back row, and the efficiency of the lamp is low, and the illumination of the class table cannot meet the requirements of the current standard.
In order to meet the needs of illuminance and uniformity, many blackboard lamps adopt dual-light source lamps and install three blackboard lamps side by side. This can indeed meet the needs of lighting, but there are many practical problems. The light distribution design of some blackboard lamps is unreasonable, causing the installation height of the blackboard lamps to be too low. The blackboard lamps emit light directly on the teacher's face, which seriously affects the teacher's work.
The general plan and advantages of lighting renovation
1. After professional lighting design, the classroom generally uses 9 38W T5 classroom grille lights and 2 36W blackboard lights, and the entire classroom power is only 414W.
2. After the classroom lighting renovation, the entire classroom power is 414W, and the classroom power density is about 5.9W, which effectively saves national energy.
3. After the energy-saving renovation of classroom lighting, the illuminance of the classroom desktop is increased to more than 300Lx, and the illuminance of the blackboard is increased to more than 500Lx, ensuring sufficient lighting for teachers and students to carry out normal teaching activities.
4. After the transformation, the uniformity of illumination on the desk and blackboard surface of the classroom far exceeds the national standard, making the overall lighting environment of the classroom softer and more comfortable.
5. The lighting transformation adopts a light source with a color temperature of 5000K, and the color rendering index of the light source is greater than 90, which can ensure that teachers and students have a real viewing angle experience.
6. Classroom lighting transformation adopts Benwei lighting professional classroom fluorescent lamp with special classroom grille lamp panel, no flicker, fluctuation depth <3.2%, and significantly improves lighting comfort.
