We owe this colorful world to the sun. Because the light emitted by the sun is a polychromatic light, monochromatic light is reflected on objects of different colors, showing the colors we see.
The complex mixed light in sunlight, arranged by different wavelengths, is the spectrum of sunlight, which contains the spectral curves of ultraviolet light, visible light, and infrared light, so the spectrum of sunlight can be called the full spectrum.
Artificial light sources are constantly striving for only one goal, and that is sunlight, because the spectrum of sunlight is capable of revealing all the colors that the human eye can see. In the field of vision, artificial light sources need to be in the visible light range with a wavelength between 400 and 800, so that the spectrum is constantly close to the sun, so that it can be regarded as a high-quality light source for color rendering. Full-spectrum light is also defined in the visible field, but a color rendering index of 98 does not mean that it is full-spectrum.
A full-spectrum lamp is a lighting product that provides a full range of visible light waves, and its color effect is close to the natural light of sunlight. The Color Rendering Index (CRI) is an indicator of how well an object renders color under a particular light source, with higher values indicating better reproduction of color. Therefore, some full-spectrum light source products may pursue a high color rendering index to achieve a better visual experience, but not all full-spectrum lamps are designed in this way, and may not have a high CRI value of 98.
Full-spectrum LED lights have three features:
1.The spectral pattern is continuous and full, with no serious bulges, no serious faults and depressions, and is very close to the spectrum of sunlight.
2.Color rendering index Ra (R1 to R8), color rendering index CRI (R1 to R15), RF color fidelity, RG color saturation these key spectral data are very high, generally required 95, 98 is considered very good, theoretically these indicators of sunlight are 100, sunny days outdoor measured sunlight these indicators are between 99-100, rainy days and shade, or there are related environmental conditions caused by shading, light absorption may be around 90-95.
3.The light color and light perception experience is real, natural and comfortable, and there will be no color casts and distortions.
One point to remind everyone, in the pursuit of full-spectrum high-quality lighting at the same time, we must pay attention to long-term reliability, for just change a full-spectrum LED products, use with caution, light decay, short life, color cast, dead lights, etc., with half a year The problem appears to varying degrees. The spectral diagram and spectral data of the full spectrum are high and low, and the quality of basic functions is also uneven. Ask more and understand more, either independently improve the ability to screen the quality of products, or choose professional and reliable professionals, or both. Consumers' ability to recognize and judge products is stronger, and they will promote the improvement and progress of the entire industry more and better!
This lamp has a color rendering index of up to RA98, which is considered to be a full-spectrum color illumination, with bright and uniform light, soft and comfortable. This desk lamp is also equipped with high-precision PE intelligent induction dimming, which can automatically adjust the light according to the changes in ambient light to achieve the effect of real AI intelligent eye protection.
