FULL SPECTRUM POPULAR SCIENCE

1.What is a full spectrum light source?

Full-spectrum light sources are the lamps that can emit the closest to natural light, because the light they emit is full-spectrum, that is, all light waves are present, including all colors of visible light and a small part of ultraviolet light.

In short, a full-spectrum light source can emit light similar to sunlight, and its color temperature is about 4000K to 5000K, which can restore the original color of the illuminated object to the greatest extent.

2. What are the benefits of full-spectrum LED lamp beads?

(1) It can emit the light closest to the natural light source, and can reach a very high Ra value.

(2)  While ensuring the brightness, the control of the color temperature is more precise.

(3) It can maintain the consistency of brightness, color rendering and voltage, which is an indispensable basis for professional eye protection lamps.

3.What is the color rendering of the light source?

We know that an object shows its true color under illumination of sunlight and incandescent lamp, but when the object is illuminated by a gas discharge lamp with a discontinuous spectrum,the color will be distorted to varying degrees.We refer to the degree to which the light source presents the true color of the object as the color rendering of the light source.In order of quantitatively evaluate the color rendering of light sources,the concept of color rendering index is introduced.

Based on the standard light source, its color rendering index is set as 100, and the color rendering index of other light sources are all lower than 100. The color rendering index is represented by Ra. The larger the Ra value, the closer the light source spectrum is to the full spectrum at this time, and the more light waves and visible light colors the light source contains.
