According to the official data of the National Health Commission, the overall myopia rate of children and adolescents in China in 2022 is 536%, including 14 for 6-year-olds5%, 36% for elementary school students, and 71 for junior high school students6%, 81% for high school students, the situation of myopia prevention and control should not be underestimated. The selection of high-quality eye-friendly table lamps to create a healthy reading and writing light environment for children has become a compulsory course for Chinese parents.
However, in view of the dazzling and dazzling eye-care table lamp market on the market, it is difficult for ordinary consumers to make rational judgments and purchase decisions. According to industry insiders, there are three major chaos in the current eye-care table lamp market: first.
First, the quality is uneven, resulting in bad money driving out good money, harming the health of consumers;Second, the "data party" uses different means to package gorgeous data, falsely advertise or exaggerate relevant parameters and indicators, and deceive consumersClause.
3. Avoid the important and light, and describe some easy-to-achieve indicators, such as no blue light hazard RG0, color rendering index RA>95, no ** flash, etc., while selectively ignoring the indicators that are difficult to do but have a critical impact on the eyes, such as illuminance uniformity.
According to medical experts, illuminance refers to the intensity of light and the degree to which the surface is illuminated, which can be colloquially understood as "brightness" (in lux or lx). Studies in the United States and Japan have found that the most suitable illumination range for the human eye should be 600-900lx, and high illumination, especially above 1000lx, will cause discomfort, and 23% of people complain that they have been troubled by reflections;Below 500lx, it will be difficult to read.
At present, the maximum illumination value of many eye-protection table lamps on the market is generally higher than 1500lx, and some even exceed 2000lx, but the minimum illumination in the specified area is only 300lx or even lower, and the difference between the two is five or six times or even greater. Too high and too low illumination and the difference is extremely obvious, which is easy to cause strong dazzling or amblyopia, and the pupil size is contracted and dilated at high frequency, which is extremely unfavorable to human eye health.
The uniformity of the eye-protecting table lamp refers to the uniformity of the light distribution in the specified operation area, and the scientific calculation method is: maximum illumination and minimum illumination. The closer the ratio is to 1, the more evenly distributed the light and the more comfortable it isThe smaller the ratio, the more uneven the light distribution, the worse the light quality, and the increased visual fatigue. Experts revealed that in order to achieve a comfortable illumination range and uniformity close to 1:1, it is necessary to use a good optical system for repeated calculation, testing and verification, otherwise it is difficult to achieve the purpose of "fish" and "bear's paw", "In this sense, most of the eye-protecting table lamps on the market have not achieved the optimal results. ”
Recently, focusing on the R&D and application of LED technology for 30 years, Shanghai Sansi Electronic Engineering Co., Ltd. has been led by Professor Zhou Shikang, an authoritative optical expert of the Chinese Academy of Sciences, and other expert teams, leading more than 500 scientific researchers, and a number of professional research institutions and colleges and universities in the United Nations, after a lot of research and verification, the leading non-imaging optical new technology and system are used in eye protection desk lamp products, and a new generation of LED health eye protection table lamp has been developed, creating a new height in this market.
It is understood that non-imaging optics is an important branch in the field of optics, which is a discipline with the purpose of improving the energy transmission efficiency of the optical system and improving the energy distribution of the target surface, which is fundamentally different from the traditional "imaging optics". Imaging optics aims to improve the imaging quality of the optical system, and focuses on the accurate transmission of optical information.
Professor Zhou Shikang is an optical expert in China, an academic leader of important national disciplines, a researcher, a doctoral supervisor, and a special allowance expert, who has been engaged in imaging optics research and design for more than 40 years, and his self-created new method of non-imaging optical design is well-known in the global optical community. In 1976, he used China's second-generation electronic computer (transistor electronic computer) to assist in the design of China's first-generation zoom cinematographic objective lens, with a zoom range of 10 times.
According to him, the significant advantages of non-imaging optical systems in lighting applications are: better control of light distribution, more uniform distribution of light in the specified irradiation area, and improve the utilization of light, reduce light waste, especially for LED solid-state light sources.
The use of non-imaging optical technology and system of Sansi eye protection desk lamp can make the illumination of the desk lamp more evenly illuminated on the desk, the illumination of the central area and the total area is very balanced, and the actual effect of uniformity close to 1:1 is achievedAt the same time, the illumination of each point in the operation area is well controlled within the comfortable level of reading and writing, and the illuminance and uniformity are "double excellent", which is more conducive to creating a high-quality and healthy reading and writing light environment, protecting the visual health of children and adolescents, and escorting the prevention and control of myopia among children and adolescents in China.
Founded in 1993 by the scientist Mr. Chen Bishou, Shanghai Sansi Electronics is a technology-based enterprise focusing on LED display, LED lighting and system integration, and has been adhering to the strategy of scientific and technological innovation, applying scientific research achievements to major projects at home and abroad, such as Hong Kong-Zhuhai-Macao Bridge, Xichang, Wenchang, Jiuquan Satellite Launch Center, New York Times Square, etc., and has undertaken the "Eleventh Five-Year Plan", "Twelfth Five-Year Plan", "Thirteenth Five-Year Plan" The leader unit of the national key project is a veritable national benchmark enterprise in the field of LED technology in China.
The physical and mental health of children and adolescents is related to the harmony and happiness of hundreds of millions of families and the development of the country and the nation. As a manufacturer and seller, it is our responsibility to develop a truly eye-friendly table lamp for consumers and care for the healthy growth of the next generation.
