What is healthy classroom lighting
At present, the deterioration of the visual health of the eyesight of students of all ages across the country is increasing. The myopia rate is increasing year by year and tends to be younger. The incidence of myopia in adolescents has remained high. In June 2016, a systematic study of the visual health white paper "National Visual Health": Among the people over 5 years old in China, the proportion of myopia is close to 40%, which is equivalent to 1 out of every three people with myopia, and the number of myopia is close to 500 million. The high level of myopia among young people not only affects the present, but also endangers the health of the people in the future, and will have a significant impact on the country's social and economic development.
Myopia mostly occurs at the elementary and middle school level. Our primary and secondary school students spend approximately 8-10 hours of study time in the classroom every day. A number of studies have shown that: at present, classroom lighting in primary and secondary schools generally has problems such as low illuminance and uneven lighting. Poor classroom lighting is one of the main reasons for the decline of students’ eyesight. In response to this situation, the concept of healthy lighting in classrooms has only been in recent years. It became hot quickly.
What is healthy lighting
Healthy Lighting aims to use new technologies to create a healthier, safer and more comfortable lighting environment. Mainly by launching a series of healthy L lighting products to achieve high luminous efficiency, no flicker, no radiation, long life and many other advantages of healthy lighting products, so as to solve the lighting problems caused by traditional classroom lighting tools from the source. The purpose of the limited prevention and control of myopia in children and adolescents is to protect children’s eyes and give them a bright future.
What are the problems with traditional classroom lighting
1. Poor light quality
(A) The glare from the direct light source is serious, which can easily cause the teacher's eyes to become tired and the students' attention will be distracted.
(B) The light source flickers high, causing eye fatigue and decreased vision.
(C) The color rendering index of the light source is low, and the spectrum of ordinary fluorescent lamps is incomplete, which will cause color loss and color cast, which will directly affect the child's color discrimination ability.
(D) The color temperature of the classroom lighting is too high and the light is white. It is easy to cause students to become excited and fatigued, and to cause myopia in students' eyes for a long time.
2. The average illuminance and uniformity are unqualified and fail to meet the requirements of national standards
3, the life of the light source is low, and the light decay is serious
Ordinary fluorescent tubes, light attenuation occurs after half a year of use, resulting in high maintenance costs and waste of resources;
4. Traditional lighting consumes high power
5. Fluorescent tubes are highly hazardous
Fluorescent tubes contain mercury, phosphors and other heavy metal substances. If the tube ruptures and leaks, harmful substances will remain in the classroom for a long time. The mercury volatilization cycle is as long as 50 years, directly endangering the health of teachers and students.
The quality of LED tubes used in school classroom lighting is often inspected from the following aspects, and 100% of the LED classroom lights produced by lighting can withstand your test:
First of all, the quality of the LED lamp chip is the soul of the lamp. The chip is the luminous body of the LED lamp, and the source and size of the chip determine the quality of the LED tube used in school classroom lighting. The LED classroom lamp chips produced by 100% Lighting are derived from imported chips, with good quality and size fully adapted to the LED lamp model;
Secondly, the colloid of the LED lamp makes the lamp icing on the cake. The general colloid components are epoxy resin, and some additives in the colloid can enhance the performance of LED lights for school classroom lighting. The LED classroom lights produced by 100% lighting use very expensive colloids, and add flame-resistant and fire-resistant materials and anti-ultraviolet interference materials. These make the LED classroom lighting more stable, and more energy-saving and safer;
Then, the brightness and light quality of the LED classroom lights are the guarantee of the lighting effect. The brightness should be evaluated by the laser level, the higher the brightness, the better the lighting effect. Hundred% Lighting has high-precision spectroscopy and other equipment, and the light quality of the LED tube used in school classroom lighting is guaranteed.
There is also the life span of the LED lamp is a manifestation of quality. The most intuitive performance of the quality of different LED lights is the service life. The length of life does not mean that the LED lamp is broken or unusable. It refers to the decay of LED light, which is called light decay. The 100% lighting LED tube uses SMD light bead technology, and the materials are all excellent, so the light decay is small and the life is long.
