LED lamp is not suitable for eye protecting lamp

In recent years, LED lamp as a new type of lighting source, gradually entered the homes of ordinary people, and energy saving, high efficiency and other advantages have been highly respected. At present, there are many LED light source eye protection lamp on the market. But Shi Zhaoyang, deputy director of the Municipal Quality Inspection Bureau, believes that, at least under current technical standards, the LED light is not suitable for eye protection. This is because LED, as a point light source, is highly susceptible to glare when used in desk lamps. Although there are many anti glare LED lights, lighting efficiency will be greatly reduced.

In contrast, high frequency energy-saving lamp fluorescent lamp and incandescent lamp, each has advantages and disadvantages, high-frequency fluorescent lamp flicker is less, but the price is slightly higher, and low frequency high frequency may be posing as incandescent lamps; good optical performance, but low efficiency and energy-saving; energy-saving lamps in the warm light source is more suitable for the eye, but rather than the white light brightness and reduced. But in general, these three lights are ideal eye light sources.

Buying skills and paying attention to using them

How can I buy qualified eye protection lamp? Reporters from the testing institutions and sales staff learned that the purchase and use should stress methods.

In addition to the regular stores to choose a 3C certified products, consumers should pay attention to: the best choice with reflector, optical products, eye at a distance of 40 cm high, the desktop from the source level distance of 60 cm, should not see the light. The lamp pole of the desk lamp is as long as possible and adjustable, and the length of the wire is not less than 1.8 meters.

When in use, read and write for more than 40 minutes, let your eyes rest. If there is an obvious dark area in sight range, it is better to turn on the ceiling light while using the eye lamp room.
