Led lamp beads, LED lights, eye damage

Since the electric light, human life has undergone earth-shaking changes. Before that, everyone can only use kerosene lamps. It is very inconvenient to go out. With the advancement of technology, incandescent light bulbs have emerged. The night brought light, and the current technology is more developed. Incandescent lamps have been abandoned by many families, and they have all used LED lights. Compared with incandescent lamps, LED lamps have obvious advantages and can save energy and electricity. However, according to relevant scientific research, the blue light source in LED lamps is harmful to human eyes. Is it really good to use LED lamps for a long time? Many people are not clear, and now regret it.

Advantages of LED lights
The first point: energy saving and environmental protection

The working principle of LED lights and incandescent lamps is different. Incandescent lamps use thermal energy to illuminate. Friends who have used incandescent lamps know that it is very hot to touch incandescent lamps after turning on the lights for a long time. Most of the electricity is wasted. It was lost and not fully utilized. The principle of LED illumination is to convert electricity directly into light energy. If the two lamps use the same amount of electricity, the LED lamp will emit much longer than the incandescent lamp. After the popularization of LED lights in China, the use of electricity for one year is more than the previous three provinces of the Three Gorges Power Station, which meets the requirements of China's energy conservation and environmental protection.

Second point: longer life

Traditional incandescent lamps are very easy to break. Under normal circumstances, they can only be used for one thousand to two thousand hours. If the lights are always turned on and off, the effect on the life of incandescent lamps is very large. The instantaneous current may be Will cause the tungsten wire in the incandescent lamp to burn out. After the LED lights entered the home, they were well received by many families because their service life can reach 50,000 hours. Although the price of LED lights is more expensive, from this point of view, it is still very worthwhile.

Shortcomings of LED lights
Blue light pollution

When the LED light is turned on, there will be blue light. If there is a family with children in the family, you need to pay more attention to this. If the child is always staring at the light, the damage to the eyes is very big, and the blue light will directly hurt. The retina causes myopia to appear in children. In the process of using LED lights, try to keep the children away from the lamps and play in a far place, and don't let the children look at the LED lights. It is very important to protect the child's vision.

Everything has a certain two-sidedness. While technology brings convenience to everyone, it may also cause harm. However, in general, the advantages of LED lights are very obvious. Although they may cause harm to children's vision, they belong to The area that can be controlled, LED lights are still very popular and edible, what do you think?
