Background

In recent years, the development of LED technology is rapid, and LED lighting products are gradually replacing conventional lighting sources due to their characteristics of energy saving, environmental protection and durability. At present, most of LED lighting light sources are white light generated after a blue LED chip excites yellow fluorescent powder, the spectral curve of the white light is not smooth, and particularly the peak value of a blue light wave band is obviously higher than that of natural light or an incandescent lamp.

The world health organization WHO loving eyes association publishes: more than 30000 worldwide are blinded each year from 2006 to 2008 due to blue light radiation. According to the data display of the ophthalmology conference of the Chinese medical society: in 4.2 hundred million net citizens in China, 63.5 percent of net citizens generate eye diseases with different degrees such as visual deterioration, cataract, blindness and the like due to blue light radiation. The existing research shows that the long-time exposure to high-intensity blue light in one day aggravates retinal macular region diseases, causes eye fundus injury after cataract operation, causes blurred vision and glare, inhibits the secretion of melatonin, disturbs sleep and also improves the incidence rate of serious diseases of a human body.

For example, in the patent with application number 201110193268.8 entitled "coated optical filter for reducing blue light harm of LED", a light absorbing material made of rare earth oxide material is coated on one or both surfaces of a substrate, and the coated substrate is placed on the light emitting path of a light source to absorb the blue light in the light source, thereby reducing the harm of the blue light to human beings; the patent with the application number of 201120329140.5 and the name of 'a blue-light-proof LED lamp' realizes the scattering of blue light emitted by a light source by arranging a fluorescent powder layer; the application number is 201320123960.8, the patent of the name "an LED eyeshield light source and eye-protecting lamp", uses green glow chip, ruddiness chip and blue and green chip, has realized having reduced the purpose of high energy blue light.

The method absorbs and filters blue light components in the light speed of the light source or lengthens the wavelength of the blue light, thereby reducing the harm of the high-energy blue light to human beings. However, the method can only reduce the proportion of high-energy blue light and cannot fundamentally eliminate the blue light.

In addition, there is also a patent that adopts a blue-free LED chip, such as application No. 201810869092.5 entitled "a blue-free low color temperature dual-band LED light source", and adopts a combination of a yellow light chip and a red light chip, but the phenomenon of uneven light mixing easily occurs by adopting dual chips, which has certain limitations.
