How important is scientific and standardized educational lighting?
The myopia problem in our country is serious. It is not difficult for everyone to find out that most of the people who see them are wearing glasses when they go out on the street. The problem of myopia in our country has aroused the attention of national leaders, and local governments have also actively promoted the transformation of educational lighting. Not long ago, the China Quality Inspection Association initiated the launch meeting of three group standards: "Technical Requirements for Smart Lighting Eye Care System in Campus Classroom Lighting", "Technical Requirements for Building Smart Lighting System and Operation and Maintenance", and "Design Requirements for Indoor Lighting and Healthy Lighting LED Lamps". The first seminar was held online.
A recent survey by the Ministry of Education found that the myopia rate of primary and middle school students increased by 11.7% in six months, of which the rate of myopia among primary school students increased by 15.2%. The lack of a good and healthy lighting environment and the lack of scientific lighting products are just important factors that cause the decline of students' eyesight.
So how important is scientific and standardized educational lighting? Let's take a look at some common lighting sources that are easy to cause damage to the eyes of students.
Incandescent lamps: Although incandescent lamps were the most widely used electric light source before, only a small part of the electric energy consumed by the filament can be converted into visible light, which has low luminous efficiency and is not energy-saving and environmentally friendly. It is gradually being replaced by new light sources.
Fluorescent lamp: It is more common in enterprises and schools. The high-voltage excitation of fluorescent materials to emit light, the high-frequency flicker of fluorescent lamps, although not detectable by the naked eye, actually causes damage to the eyes and is easy to fatigue. At the same time, fluorescent tubes contain heavy metals such as mercury and phosphors, which can cause harm to the environment and humans.
Energy-saving lamps; although energy-saving is achieved, the problems of stroboscopic and glare are prominent when used in the classroom, which is not conducive to the protection of eyes.
Ordinary LED lights; there are problems such as stroboscopic, blue light hazard and insufficient display index, which are prone to eye fatigue.
The best light source is actually natural light. This kind of light source with high light intensity and good fluidity can effectively reduce eye pressure and give students the best eye care. In this regard, the LED eye-protection grille classroom lamp developed and produced by Benwei Lighting strictly follows the six standards in the "Hygienic Standards for Daylighting and Lighting in Primary and Secondary Schools and Schools" to create a true natural light learning environment for children.
No glare, no glare, effectively improve students' attention, improve learning and work efficiency; less than 3.2% of the non-hazardous level fluctuation depth, eliminate stroboscopic, greatly reduce eye fatigue, and effectively prevent myopia; at the same time, there is no blue light hazard, no harmful light, Passed the health light IEC-62471 photobiological safety certification; energy saving and environmental protection, more than twice the energy saving than traditional lamps, all raw materials of the product have been tested by RoHS and are free of harmful substances such as mercury and lead.
