LED lamp, is not suitable for eye protection lamp

In recent years, LED lamp as a new type of lighting source gradually into the homes of ordinary people, and energy saving, high efficiency and other advantages of the highly respected, the market has been a lot of LED light source eye protection lamp. But Shi Zhaoyang, deputy director of the municipal quality inspection believes that, at least in the current technical level, LED lamp is not suitable as eye protection lamp. This is because the LED as a point light source for the table lamp is easy to produce glare. Although there are a lot of anti glare LED lights, but also greatly reduce the efficiency of lighting.

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 generally speaking, these three kinds of lamps are more ideal eye protection lamp light source.

Have the skills to use, pay attention to

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.
