"eye protection lamp" is just a marketing concept
Recently, Ms. Wang wants to choose an eye-protection lamp for her children, but there are a lot of eye-protection lights on the market, I don’t know how to choose. “The energy-saving lamps that most of my friends bought, but I also saw some LED lights in the market, is it better?†
(The eye protection lamp currently does not have a national standard and needs to be cautious when purchasing.)
When the reporter visited the market, he also learned that the same table lamp, the table lamp with the words "eye protection", is a few hundred dollars more expensive than the ordinary table lamp. And some LED "eyes", the price is even higher.
According to industry insiders, a few years ago, some people were arguing whether there was any meaning in eye-protection lamps, and even a "low-frequency lamp with stroboscopic, high-frequency lamps can protect the eyes", in fact, the low frequency is 50 Hz, which is the normal frequency. The high frequency is higher than this value, such as 100 Hz, 400 Hz, or even more, but the frequency of 50 Hz can not be discerned by the human eye, and the frequency is not high enough. “In fact, the eye-protection lamp itself is a concept, there is no need to say it is mysterious.â€
Wang Li, general manager of Shilihe Lighting City Haojue Lighting, also said that the market for table lamps is still chaotic, whether it is energy-saving lamps or LED lamps. Some small companies are eager to pursue cost-effectiveness, and the materials used are not closed. The "eye-protection lamps" produced may be no promises. Yang Haifeng, director and president of Nanjing Handerson Technology Co., Ltd., also believes that the design of the lamp will require higher color rendering and other conditions in the selection of the light source. "But there must be higher requirements for eye protection. Did not go to development."
Whether "eye protection" is still inconclusive
Li Mingwu, Ph.D. in ophthalmology and deputy chief physician of Peking University People's Hospital, said that "eye protection lamp" has always been a controversial thing. There are many studies in the industry about incandescent lamps, energy-saving lamps and even LED lamps. Some studies have shown that LED lamps are not good for visual therapy, but they are still in the state of research and it is difficult to form a guide for public life.
He Wei, general manager of Colliers International Lighting Harbor, believes that “eye-protection lamps†are not regulated by national standards. Although many companies are doing them, they are only a conceptual product that sells more expensive than general products. However, brand enterprises The products do work on quality. Lin Sheng, a Beijing-based agent of Philips, said that the “eye-protecting†products will raise higher requirements in terms of brightness and color rendering in accordance with the needs of scientific eyes.
According to industry insiders, the so-called "eye-protection lamp" is called "reading and writing table lamp" in the standard. It has the national standard GB/T9473-2008 "Reading and writing operation table lamp performance requirements" to regulate, including color temperature and color development. Index, illuminance, etc. However, the types of light sources mentioned in the standard include only tungsten filament lamps and tubular fluorescent lamps. According to Chen Yansheng, halogen lamps and energy-saving lamps that consumers often see are included in the category of tungsten lamps and tubular fluorescent lamps. The LED lights that have not been mentioned in the standard are not used for reading and writing table lamps, but the current standards are not perfect, and there will be corresponding specifications in the future.

Recently, some consumers said that it is very confusing to choose "eye-protection lamps" for children. Although some friends recommend energy-saving lamps, it seems that the LED lamps that are sold in the market are more energy-efficient and environmentally friendly. However, most industry experts have said that “eye protection lamps†are still mostly marketing concepts. Whether there is “eye protection†effect is not certain. Brand products with “eye protection†function will have higher quality. Claim.
