The blue light damage of LED table light (part one)

by Wedding Dresses wedding dresses

The main reason is the high-energy short-wave blue light.

The reason why LED table lamps source can emit white light is mainly formed by 450 ~ 455NM wavelength phosphor excitation blue light and the lower wavelength has a stronger firing. Generally, LED light source wavelength is usually shipped in the control of 500NM, about 450 ~ 455NM or 455 ~ 460NM, which are among the strongest segment of radiation damage. If the wavelength becomes large, the excite ability of the phosphor is on the decline and so the luminous efficiency is reduced. In pursuit of brightness, manufacturers usually enhance the strength of blue LED light while the human eye see such a source of long-term, it will inevitably hurt the eyes. For the household use, it is best to minimize the use of LED lighting, especially the LED Eye is in the experimental stage, LED is only suitable for auxiliary lighting.


Study of the German ophthalmologist Professor Lee Chad • Funk (RHW Funk) reported that when "inappropriate light" has continuous irradiation of our eyes, it can cause dysfunction, especially the irregular frequency high-energy short-wave blue light that contains in a lot of three-color lights, computer screens, etc. These very high energy short-wave blue light can penetrate the lens directly to the retina, causing photochemical damage to the retina, the macula, directly or indirectly lead to cell damage.


So, for the normal people, obstructing the prolonged exposure to blue light is the most effective way to reduce the damage, and use the anti-blue glasses can effectively solve this problem. Ordinary glasses can only filter ultraviolet radiation and certain electromagnetic radiation, and not filter blue light. Dedicated anti-blue glasses is not only able to effectively isolate the UV radiation and can filter more than 90% of the blue light, which is suitable for use when watching TV or using the computer, you can greatly reduce the blue eye irritation, eliminate eye soreness, fever or pain and other symptoms, relieve eyestrain.


For energy-saving products, the degree of the community attention is more than that at any time in the past, in which a light source which is called the fourth-generation dual LED in promoting industrial capital and government subsidies in recent years achieved explosive growth. Yet in the midst of joy, some experts in medicine and electric light pointed out that there is a serious blue overflow problem for many LED lights. For over time use, it will be irreversible damage of the human eye retina, serious and even lead to blindness. So between saving and health, how do we find solution choices?
