Eye protection is crucial during winter and summer vacation.

Every year, winter and summer holidays are the peak sales of eye protection lamps. In order to make children grow up healthily, parents always choose the product of "scientific name" for "reading and writing table lamps". However, reporters learned yesterday from the Changzhou quality inspection institute that at present, the qualified rate of mainstream eye care products in the market is only 8%, and the unqualified eye protection lamps can not only protect their eyesight, but also hurt their eyes.

Many brands, low-priced products account for the bulk.

Reporters interviewed in Changzhou five intersection shopping malls, Jinqiao market, Luqiao market and a number of hypermarkets found that at present, there are hundreds of brands of eye care lamps sold in the Changzhou market, and the price ranges from 30 yuan to 300 yuan. Among them, 30 yuan -70 yuan price eye care lamp occupies about 8 of the market. The eye protection lamp has both its own light source and the required light source specifications.

Comparing the low price lamp and the high price lamp, it seems that only the material is good or bad, and the workmanship is coarse.

LED lamp is not suitable for eye protection.

In recent years, as a new type of lighting source, LED lamp has gradually entered the homes of ordinary people, and has been highly praised for its advantages such as energy saving and high efficiency. At present, there are many LED light source eye protection lamps on the market. But Shi Zhaoyang, deputy director of the Municipal Quality Inspection Institute, said that at least under the current technical level, LED lights are not suitable for eye protection. This is because LED, as a point light source, is prone to glare after being used for desk lamps. Although there are many glare LED lights at the moment, the lighting efficiency is also greatly reduced.

In contrast, high frequency fluorescent lamps, incandescent lamps and energy saving lamps have their own advantages and disadvantages. High frequency fluorescent lamps have fewer flashes, but the prices are slightly higher and have the possibility of low-frequency posing as high frequency. Incandescent lamps have good optical performance, but low efficiency and no energy saving. Lower. But generally speaking, these three kinds of lamps are ideal light source for eye protection.

Buying skills, using attention

How can I get a qualified eye protection lamp? Reporters learned from the testing agencies and sales staff that purchase and use should be emphasized.

In addition to choosing products with 3C certification to regular shops, consumers should also pay attention to: the best choice is to produce products with reflectors and undershoots. When the eyes are 40 centimeters high from the table and 60 centimeters away from the light source, they should not be able to see the light source. The lampposts of the table lamps should be long and adjustable as far as possible, and the length of the wires should be no less than 1.8 meters.

When using, read and write for more than 40 minutes, and let your eyes rest. If there is a dark area in the line of sight, it is best to turn on the ceiling lamp in the room using the eye protection lamp.
