Let's talk about how to create a high-quality lighting environment in the classroom to meet the standard?

2021-06-26

At present, the vision health of children and adolescents has attracted great attention, and the influence of classroom lighting on myopia has also been concerned. The Ministry of education has also issued relevant standard documents, such as "Hygienic standard for daylighting and lighting in primary and secondary school classrooms gb7793-2010", "work plan for prevention and control of myopia among primary and secondary school students" and "guidance on strengthening prevention and control of myopia among children and adolescents"

So, what kind of lamps and lanterns are needed to create a high-quality lighting environment in the classroom? Among them, the hygienic standard for daylighting and lighting in primary and secondary school classrooms stipulates the requirements for daylighting and lighting in classrooms

1. All classrooms should be equipped with artificial lighting;

2. The average illumination value on the classroom desk should not be less than 300lx, and the uniformity of illumination should not be less than 0.7; The blackboard in the classroom should be equipped with local lighting, whose average illumination value should not be less than 500lx, and the uniformity of illumination should not be less than 0.8;

3. The light source with 3300k-5500k color temperature should be used, and the color rendering index of the light source should not be less than 80;

4. The uniform glare value (urg) of the classroom should not be greater than 19;

5. Under the condition of maintaining the average illumination value of 300lx, the current value of classroom lighting power density is not more than 11W / m ², The target value should be 9W / m ²; 6. When calculating the illuminance in lighting design, the maintenance coefficient should be 0.8;

In the second point, "the average illumination value on the classroom desk should not be less than 300lx" stipulates that the average light on the desk should be bright enough. Spot check shows that most of the classrooms with fluorescent lamps have less than 200lx average illumination on the desk and blackboard. Therefore, it is suggested that the lighting lamps in these classrooms should be replaced with LED lamps with higher luminous efficiency, so that the illumination on the class desk in the classroom with the same number of lamps should not be less than 300lx.

There are also "classroom blackboard should be equipped with local lighting, its average illumination value should not be less than 500lx, illumination uniformity should not be less than 0.8", which requires that the blackboard area lighting should be independently responsible for lamps, and the minimum lighting requirements are higher than the desktop.

The third point "3300k-5500k color temperature light source should be used in classroom" regulates the color temperature range of classroom light source. The color temperature of traditional fluorescent tubes is generally above 6500k, high color temperature, light color is too white, easy to lead to students' eyes excited, accelerate fatigue.

In addition, "the color rendering index of light source should not be less than 80" standardizes the authenticity requirements of educational lighting light source for object presentation. The color rendering index of traditional fluorescent lamps is between 70 and 80, which is slightly lower than the national minimum standard. Too low color rendering index will cause visual color distortion, and it is easy to cause serious vision problems such as color blindness and color weakness of students in the long run.

If the classroom wants to create a high-quality lighting environment, it is recommended that all primary and secondary schools and institutions (including: public school classroom lighting, private school classroom lighting, private school classroom lighting, experimental school classroom lighting, educational institutions, etc.) choose "Huahui lighting"!

As a school lighting health promoter, Huahui lighting is one of the first batch of high-quality classroom lighting units in South China. It is also one of the "top ten education lighting brands" in China's lighting industry in 2020. It strictly controls the color temperature, glare, blue light, illumination and other problems in education lighting, so as to avoid harmful lighting to students' eyesight health!

Led eye protection classroom lamp and led eye protection blackboard lamp are specially designed for classroom lighting, which meet the national standard. The average (constant) illumination of desk is more than 300lx, and the illumination uniformity is 0.7; The blackboard maintains an average (constant) illumination of 500lx, and the uniformity of illumination is 0.8; The color rendering index is more than 90 and the color reduction is high; Grid anti glare design, glare value is less than 16, no glare; Color temperature is 5000K, comfortable and soft; The illumination of the whole classroom is uniform, without stroboscopic and blue light hazards.

Huahui led eye protection classroom lamp and led eye protection blackboard lamp can be used together with Huahui lighting aiot intelligent education lighting overall solution. Through self-developed intelligent lighting products, equipped with self-developed intelligent box (such as intelligent power distribution box or intelligent air switch), intelligent full touch screen scene switch, remote control or mobile app can be used to easily switch the lighting mode that meets the needs of teaching, Realize the constant illumination of the whole classroom, one button scene control, curtain linkage, UV sterilization and other intelligent needs!
