The visual effect of human eyes consists of many complex factors, which vary from person to person. Illuminance is the most basic technical index of visual light environment. It refers to the luminous flux obtained per unit area of the illuminated object. Sufficient light is the prerequisite to clearly see an object.
In the darkness without light, the visual organs will lose their function, and everyone's inner emotions will become confused, afraid, anxious and painful. When the illuminance is suitable, it is easy to see objects clearly, distinguish small fonts and images, have high resolution and human eyes are not tired. On the other hand, under low illumination or insufficient illumination, the small font can not be seen clearly, the discrimination ability is low, and the eyes are easy to fatigue, damage and myopia.
Therefore, each classroom lamp for classroom lighting must have a scientific and reasonable illuminance standard value, and the illuminance distribution must be carried out correctly.
For students, if the lighting environment of the classroom is comfortable and well-equipped, the learning efficiency can be greatly improved. According to the hygienic standard for daylighting and lighting in primary and secondary school classrooms (gb7793-2010), the maintained average illuminance on the classroom desk should not be less than 300lx, and its illuminance uniformity should not be less than 0.7. The classroom blackboard should be equipped with local lighting, and its maintained average illuminance should not be less than 500lx, and the illuminance uniformity should not be less than 0.8. The national standard classroom illumination is 300lux.
Not only the illumination should meet the requirements of national standards, but also the classroom lighting should meet the requirements of national standards. 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), classroom lamp OEM and OEM choose the brand of "Huahui lighting"!

It strictly controls the color temperature, glare, blue light, illumination and other problems in educational lighting to avoid the harm of bad lighting to students' visual health!
Huahui lighting is specially used for classroom lighting lamps - led eye protection classroom lamp and led eye protection blackboard lamp, which meet the national standard. The average (constant) illumination of the desk is greater than 300lx and the uniformity of illumination is 0.7; The blackboard maintains an average (constant) illumination of 500lx, and the illumination uniformity is 0.8; The color rendering index is greater than 90, and the color reduction is high; The grid anti glare design is adopted, and the glare value is less than 16, which is not dazzling; The color temperature is 5000K, comfortable and soft; The illumination of the whole classroom is uniform, without stroboscopic and blue light hazards.
Using Huahui led eye protection classroom lamp and led eye protection blackboard lamp can be combined with Huahui education lighting aiot intelligent education lighting overall solution. Through the self-developed intelligent lighting products, equipped with self-developed intelligent boxes (such as intelligent distribution box or intelligent air switch), the intelligent full touch screen scene switch, remote control or mobile phone app can easily switch the lighting mode that meets the needs of teaching, so as to realize constant illumination, one key scene control Curtain linkage, ultraviolet sterilization and other intelligent needs!
