Inferior LED lamps on the human body

　　In recent years, the development of LED lighting presents a bustling scene. Like other artificial light sources, LED light radiation can also cause little theoretically harm to humans. Damage occurs mainly in people's eyes and skin, such as photochemical damage the skin and eyes, and near ultraviolet harm the eyes, blue photochemical retinal damage, retinal photochemical damage lens, retina damage and skin thermal heat hazards, and both being more vulnerable eyes. In addition, LED can cause glare hazards. Glare is on the horizon because of the brightness distribution or range inappropriate, or in space or time the existence of extreme brightness and contrast, as well as causing discomfort and reduce the visibility of objects in the visual conditions, evaluate the quality of lighting glare is one of the most important factors .

　　Following the radiation hazard has been identified as "air, water, noise" outside the fourth largest environmental safety issues facing humanity World Health Organization. Optical radiation is an important part of the radiation, its ultraviolet radiation and blue light radiation on the human body particularly significant. In recent years, with the development of LED technology and market requirements, the radiation brightness LED chips greatly improved, more and more narrow beam, plus part of the manufacturer and excessive application of LED UV blue band chip, making the LED light radiation hazards become one can not be ignored. LED light radiation hazards is mainly reflected in the near-ultraviolet radiation damage of the eye, the retina blue photochemical damage and radiation heat damage.

　　In theory, the use of the type of lamps, LED lights on people's health (not only refers to the eye) injury minimum, or even that there is no harm. Of course, the premise is sure to use regular brand manufacturers qualified, CCC certification through domestic or foreign UL, CE and other types of security, electrical certification of LED lights. If you use poor quality LED lights, it is better not.
