‌   The principle of full-spectrum eye protection lamp ‌ is mainly based on simulating the spectrum of natural

 light to provide a lighting environment closer to natural light, thereby reducing visual fatigue and eye 

discomfort. The design of this lamp is designed to ensure that the human eye development needs different 

wavelengths of light,　by simulating the spectrum of sunlight, to ensure that the three-layer structure of the

 eye wall (fiber membrane, vascular membrane, retina) can get proper nutrition, to ensure normal growth 

and development of metabolism. Full-spectrum eye protection lights use high-quality LED light sources to 

provide uniform, bright lighting effects，no matter in which corner, you can feel bright and comfortable light, 

making the space more pleasant.　In addition,　the technical and design cost of full-spectrum eye protection

 lamps is high, and the　market competition is less,leading to its relatively high price, but this does not prove 

that it is an IQ tax, but the result of market supply and demand relations and product positioning ‌.

   The concept of the full spectrum is derived from physics, which refers to the spectrum containing ultraviolet

 light, visible light, infrared light spectral curve, and the ratio of red, green and blue in the visible part 

of the spectrum is similar to sunlight, and the color rendering index Ra is close to 100 spectrum. This spectrum 

should change color temperature with time, simulate the natural light environment, in order to be more

 in line with the natural growth law of organisms. Ordinary LED in the blue spectrum is relatively high, the lack

 of violet light, blue light, short-wave green light and long-wave red part, and the full spectrum LED 

by adding violet chip or add the blue peak and phosphor peak between the concave region wavelength

 phosphor to complete the spectrum, in order to simulate　5000K solar spectrum ‌.

   To sum up, the full-spectrum eye protection lamp provides a comfortable and healthy lighting environment

 by simulating the spectrum and color temperature changes of natural light, aiming to reduce visual fatigue

 and eye　discomfort, while ensuring the normal development and metabolic needs of the eyeball.
