High-frequency flash priming, no stroboscopic eye protection, the market is full of



Recently, when I visited the Shanghai lighting market, I found that many retailers gradually began to add eye protection lamps to their showcases. With the advancement of the times and the gradual improvement of people's understanding of lighting products, the stroboscopic eye-protection lamp has gradually become one of the major items purchased by the Shanghai family for children.

After asking the merchant, the author learned that the eye-protection lamp currently on the market is more than a few hundred dollars, and the price is several times higher than that of the ordinary table lamp. Experts pointed out that most eye-protection lamps on the market are actually energy-saving lamps and do not have eye protection functions.

Relevant experts explained that what the merchants call "no stroboscopic" is actually just "high frequency flashing". Under the action of alternating current, the fluorescent lamp will produce a change of light and light, that is, stroboscopic. The strobe of an ordinary fluorescent lamp is about 100 times per second, and although it is not easily noticeable to the naked eye, it still feels uncomfortable. When the light flashes faster every second, it will feel more comfortable relative to the eyes. However, compared with the price of ordinary energy-saving lamps, the price of eye-protection lamps can be up to tens of times higher, and 30 yuan from ordinary lamps can jump to more than 300 yuan.

According to industry sources, there are some real eye protection lamps. However, due to the complicated production process and high technical content, coupled with the limitation of LED cost, the retail price is around 1,000 yuan, so it is not suitable for marketing. However, at this time, some small processing factories aimed at the market, and carried out a large number of second-hand processing, which made the eye-protection lamp market appear extremely chaotic.
