Analyze LED Blu-ray to teach you to buy LED lights

The use of LED lights is an energy-saving way, and it also has the peculiar effect of incandescent and fluorescent tubes.
But the human eye does not fit all the LED lights as everyone imagines. But what consumers need to know is that each type of lamp has a level of safety and a level of danger. Understanding the necessary knowledge and standards not only helps producers and lighting designers to better choose between different levels, but also allows consumers to make rational judgments.
Is the LED light really harmful?
The light of the LED bulb comes from the short-wave high-energy blue light. In the LED blue light damage problem, the opinions of the industry and experts are not completely consistent.
Blue light is the light that exists in nature and is an important part of sunlight. It also exists in various white light sources. Many LED lamps on the market today use blue light from the chip to excite yellow phosphors to reconcile into white light. This white LED lighting product has a richer blue light spectrum than Other light sources. It is generally believed that exposure to blue light will not harm the eye for a few hours, but years of exposure may cause cumulative damage.
It is also suggested that age-related macular degeneration may be related to LEDs and the like.
"Recent studies have shown that blue light spectrum may cause damage to the retina and may even lead to age-related macular degeneration." The American Macular Degeneration Foundation said, "The retina can be damaged by high-intensity visible blue or violet light. Penetrating the macular pigment in the eye. According to a study by the Spiebens Eye Institute, low-density macular pigments allow more blue light to penetrate, reflecting the risk of age-related macular degeneration."
The objection is that there is no strong evidence to support this claim.
“I am surprised that blue LEDs increase the risk of age-related macular degeneration. The exposure to blue light in the sun is much more than this,” says an American ophthalmologist. “From a physics perspective, high-energy blue light or ultraviolet light can cause eye damage. But this must be exposed to the sun during childhood, because then the light can reach the retina. This means there will be very A long incubation period, long before the age-related macular degeneration was discovered."

It adopts high-quality battery monomers grouped and screened and designed by special mechanical structure to assemble all ranges of built-in BMS batteries.
