School lighting reform, health is the last word

　　 As the new crown pneumonia epidemic is under control, and the target time for the comprehensive prevention and control of myopia in children and adolescents in my country in 2023 is approaching, the renovation of classroom lighting in domestic primary and secondary schools continues to accelerate, and more and more regions and schools announce classroom lighting updates Lighting system. At present, there are related mandatory standards for school classroom lighting in our country, but the technical parameters in the standards are obviously lagging behind the current technological development of the lighting industry. Therefore, various regions and different teams in my country have successively issued corresponding classroom lighting recommendations to further standardize and improve the relevant technical requirements for classroom lighting.

　　 On the basis of following the national mandatory standards, different regions and different enterprises in our country also have their own strengths, and have developed and manufactured classroom lighting lamps with different specifications, different models, different functions, and different technical parameters. For example, from 2020 to 2021, a lighting company united with a charity foundation to donate a number of classroom lighting fixtures to Weifang, Shandong. This batch of lamps has a different appearance from our common lamps, and is closer to high bay lamps. However, from the perspective of the parameters described, they are consistent with or even higher than the relevant national standards. For another example, a listed company launched a classroom lighting fixture with 'lighting additional ultraviolet sterilizerThe lamps are different, but everyone has noticed the urgent need for 'health' in classroom lighting.

　　 However, in many classroom lighting renovations, most of them only noticed the improvement of lighting technical parameters, and did not integrate the entire classroom space for improvement. We must know that when we children and adolescents study in the classroom space, they are not only exposed to lighting, but also the entire space environment. Therefore, comprehensive prevention and control of myopia in children and adolescents and protection of the physical and mental health of children and adolescents require not only healthy lighting, but also a comprehensive and healthy classroom environment.

　　 An all-round healthy classroom environment requires healthy air and healthy school supplies in addition to healthy lighting. The classroom is a crowded public place. In order to ensure the learning environment, the space is relatively closed. Therefore, the air circulation is relatively slow. For this reason, it is necessary to purify the classroom air to a certain degree. At the same time, a large number of school desks and other school supplies also need to be sterilized to ensure hygiene and health. Therefore, a healthy classroom environment requires healthy lights, healthy air, effective sterilization and clean walls and floors.

　　 In this regard, Guangdong Kaixi Ouguang Health Co., Ltd. specially developed a photo-negative ion technology and obtained a number of patents to ensure a healthy environment in the school classroom space. Light negative ion technology is an advanced scientific research result combining light health technology and negative ion technology. It has excellent performance in improving lighting, purifying air, sterilizing and disinfecting functions.

　　 In terms of improving lighting, the photonegative ion technology adopts the concept of simulating sunlight, fully imitating the sunlight at 8 or 9 o'clock in the morning, and adopts unique light health formula technology. This technology has won the national 973 project chief scientist, eye Professor Ge Jian, the lifetime honorary director of the State Key Laboratory of Science and the doctoral supervisor of the Ophthalmology Center of Sun Yat-sen University, is highly recognized. Professor Ge clearly pointed out that 'photonegative ion technology needs to be promoted.' Casio, together with the Ophthalmology Center of Sun Yat-sen University, and the Second People's Hospital of Foshan, launched the 'Research on the Effectiveness of Artificially Simulated Natural Light Sources in Delaying the Progress of Myopia in School-age Children'. The project has won the 2019 Guangdong Basic and Applied Fundamental Research Fund Joint fund project support. A few days ago, the photonegative ion technology launched by Casio Health Company was applied to school classrooms for the first time, and it was replaced and installed in the Fourteenth Middle School of Foshan City with Casio Health lamps. The photonegative ion lamp not only has a great improvement in the quality of the light source, but also has an increase in the application function. It can realize the sterilization and disinfection of the classroom space and air purification at the same time, so that children and adolescents can have a natural, fresh and healthy learning environment. .

　　 In terms of purifying the air, the photonegative ion technology adopts the concept of simulating nature, fully imitating the environment such as forests, waterfalls, and seasides with dense negative ions. The unique negative ion generator packaging module technology can make the classroom space like a forest. Like full of fresh air. Appropriate amount of negative ions fill every corner of the classroom space through reasonable exercise. On the one hand, it cleans the dust in the air, and on the other hand, it outputs sufficient negative oxygen ions, so that school teachers and students can enjoy the breath of nature in the classroom. On the other hand, the negative ion itself has the function of sterilization and disinfection, and completes the disinfection work by adsorbing some bacteria in the air. In this way, the photonegative ion technology can fully meet the sterilization requirements of the school classroom space, and bring a safe and hygienic space environment for teachers and students.

　　 In summary, the school classroom lighting reform, health is the last word. This 'health' is not only the health of lighting, but also the health of the entire classroom space. It is hoped that many school classroom spaces in my country will soon apply photonegative ion technology, and make due contributions to the realization of a healthy China strategy, the realization of the goal of comprehensive prevention and control of myopia in children and adolescents, and the healthy growth of adolescents.
