A survey conducted by guangzhou original semiconductor lighting co., LTD on the lighting project of yihe experimental primary school proves that students and teachers in the school are satisfied with the lighting effect of LED lights. According to the test data of the use effect, yihe experimental primary school has saved 26,280 KWH of electric energy and 26,280 yuan of electricity cost since it put on LED lights in April this year. The emission of carbon dioxide, nitrogen oxide and sulfur dioxide has been reduced by 26.8 tons, 0.5 tons and 5.5 tons respectively. Meanwhile, the maintenance cost of lamps has been saved by 13,500 yuan.
Campus classroom lighting calls for LED lamps
In 2004, guangzhou issued a letter to the ministry of science and technology proposing to promote the use of LED lighting products in schools to improve classroom lighting, protect the eyesight of young students and improve learning efficiency. This successful cooperation with guangzhou yihe experimental primary school has finally made a good start for the promotion of the industry.
According to the latest data, among the nearly 400 million nearsighted people in China, the rate of myopia among teenagers is as high as 80 percent. Experts believe that the incidence of myopia is closely related to environmental factors, among which classroom lighting is one of the most important factors. Chongqing university, professor, school of architecture planning and national low carbon building lighting lighting research research director professor yong-hong yan in the semiconductor lighting 'in an interview, the research experiments show that compared with fluorescent lamps, the LED is easier to meet the requirements of spectrum security, under the same color temperature and intensity of illumination, LED has the better visual effect, more conducive to students eyesight health, alleviate intense sentiment, improve the learning efficiency. In yong-hong yan professor is responsible for the national natural science fund project 'health based on the biological effects of light classroom lighting research, the subjects under the different intensity of illumination of test research was conducted on the psychological and physiological reaction, the light and the learning efficiency and visual fatigue, brain fatigue experiments show that the white light color temperature around 4000 ° K light source recognition rate curve best stability and recognition rate.
According to the introduction, LED lights have greater advantages than fluorescent lights, with a very large market potential. The reason why LED lighting has not formally entered the field of classroom lighting in China is, first of all, the price of LED products. The high price forms the bottleneck of LED product promotion. Even though the public is aware of the advantages of LED lights in environmental protection and energy conservation, the price and quality of LED lights are still prohibitive to the public, leading some potential consumers to lack confidence in LED products.
In recent days, the original semiconductor lighting co., LTD., guangzhou technical team, through constant efforts of many years, through integration of the advantages of advanced technology, realized the electrical, optical, thermal, materials revolutionary in four areas of innovation, first to solve the difficulties in the popularization application of the LED lighting, greatly reduce the cost of the LED products, to market a very high cost performance products, gained widespread praise of the masses.
Guangzhou original semiconductor lighting co., ltd. is one of the earliest high-tech enterprises to develop the LED lighting field, so it has special feelings for the LED industry. In the first time, we came up at home and abroad and the LED industry step by step, growth, development together, we feel like the eldest son of the industry, shoulder the responsibility of the industry more, we hope that through our hard work than others, for better and faster development of the domestic LED industry.' Peng zhoulong, general manager of the original lighting co., LTD.
Relevant person in charge of the original also introduced to the reporter, the original products are all tested by the authority, through CE certification and ROHS and other certification. At the same time, it has applied to the state Patent Office for scientific and technological achievements of innovation and development, and obtained a number of patents for inventions and utility models of the state intellectual property office. Original lighting has been powered by scientific and technological innovation, research and development of new products with great concentration, as early as 2005, the original will launch 'the world's first light practical high power LED lighting lamps', the product won in Geneva, Switzerland world invention in silver, and in guangzhou ersha island independently established the world's first high power LED street lamp demonstration project, in the development of LED lighting one step a footprint, laid a solid foundation.
An excellent paper on 'project for the people'
It is understood that after half a year's use of LED lights in yihe experimental primary school, the original completed the survey on the project's engineering effect as required, and finally got a satisfactory answer. Since the original LED fluorescent lamp after entering the classroom, with illumination of white light color temperature of 6200 ° K, change to 4020 ° K, classroom desktop illumination from an average of 210 lx increased to 308 lx, and the lighting intensity of your output is extremely stable, stroboscopic depth is only 3.76%, no ultraviolet radiation leak, all the data above shows that the LED fluorescent lamp than traditional fluorescent lamp is more advantageous to the students' eyesight health, is helpful for the improvement of the learning environment, indirectly increased the concentration of the student's mental activity and thought, to improve the quality of teaching and learning achievement has the certain help.
Peng said, 'such a small school, a mere 1,000 LED fluorescent tubes, produces energy saving benefits and social benefits are so obvious, not only energy saving and pollution reduction, low-carbon environmental protection, but also far-reaching impact on students' learning and vision health. Therefore, LED, an excellent green lighting source, should be vigorously promoted in the field of classroom lighting, which is undoubtedly beneficial to the learning and health of the next generation, and good for the country and the people.
The survey data of this project also proves that none of the original LED daylight lamps used in schools have been damaged since they were installed and used for more than six months. However, the failure rate of ordinary fluorescent lamps is usually between 1 and 3%, and the maintenance cost is much higher than that of LED lamps. It can be seen that LED lights save energy and a considerable amount of maintenance costs, and LED lights light attenuation is only 0.8%, that is to say, the normal use of more than 8 years, with a long service life.
