"Three Standards" in the Guide to Choosing Eye-protection Desk Lamp

According to a recent survey, the incidence of myopia is 22.78% for primary school students, 55.22% for middle school students and 76.74% for college students. According to statistics, among the workers and many students who have been engaged in copywriting for a long time, many patients are nearsighted because they use inappropriate desk lamps. Today, when advocating the fashion of "energy saving, health and environmental protection", eye protection desk lamps have become the first choice for many consumers to buy desk lamps.

Although the reasons for teenagers' poor eyesight are complicated, experts believe that long-term use of eyes in dark and frequently flashing light is an important cause of eye fatigue, which eventually leads to myopia and other eye diseases. Consumers are often dazzled when purchasing, and sometimes they have to choose according to price, style and color, which has certain blindness. In fact, what is the real "eye protection desk lamp"? Experts teach you three selection criteria.

First of all, it is considered that the most fundamental essence of eye protection desk lamp is to solve the problem of stroboscopic. The eye protection principle of eye protection desk lamp is to use electronic ballast that can reduce stroboscopic light, which can convert 50Hz AC electric signal into high-frequency signal with stable amplitude, thus reducing the influence of stroboscopic light on eyes. Experts in electric light sources have analyzed stroboscopic lighting: stroboscopic lighting does cause eye discomfort. For example, ordinary fluorescent lamps produce 65,438+000 flashes per second, which can't be adapted by human eyes. But when the number of flashes per second increases to a certain extent, it will be difficult for the naked eye to detect and the eyes will be relatively comfortable.

Secondly, the eye protection desk lamp with good quality uses tricolor lamps with good color rendering. Compared with ordinary desk lamps, its light color is soft and very close to natural light. Leading brands of eye-protection desk lamps in the market, such as Philips, all adopt energy-saving lamps to truly restore color and ensure this in a long service life, thus improving the comfort of eyes.

Third, the brightness is reasonable and there is no glare. Dazzling light makes people feel dazzling, and in severe cases, it can cause eye diseases. The professional optical design lampshade of eye protection desk lamp, equipped with reticulated aluminum reflector and aluminized high-efficiency gridded light barrier, reduces the contrast between the illuminated area and the non-illuminated area, controls the light output direction and desktop illumination more effectively, completely eliminates the direct glare and reflected glare generated by the light source, and ensures high-quality illumination with stable brightness and reasonable contrast, thus ensuring eye health. Experts remind that for consumers, buying eye protection desk lamps must not be based on the single concept promoted by manufacturers or for the sake of cheapness, but it will not achieve results after spending money.

In addition, LED, as a recognized environment-friendly and healthy light source, is also widely used in the field of eye protection desk lamp light source. Due to technical reasons, the original LED light source can not solve the defects of low light energy utilization and insufficient brightness, so it has not been widely used. With the development of LED light source technology, more and more eye-protection desk lamp enterprises are vigorously developing corresponding LED eye-protection light source products. Over time, environmentally friendly and healthy LED light source products will surely become the first choice for eye protection. In terms of product innovation, LED will become the next light source focus of eye protection desk lamp, and the innovation of product material and modeling will keep up with the fashion trend, and cartoon and elegance will be the same theme.
