Q: What is Full Spectrum?

A:Full spectrum is the spectral effect of an artificial light source that is infinitely close to the sun’s rays.

We can see the shape and color of any material because the light hits the surface of the object, reflects or refracts the light,

and is seen by the pupil of our eye. Whether it is natural light such as sunlight, moonlight, lightning, or artificial light such

as electric lamps, matches, and fire, their irradiation principles are basically similar.

 

Everyone has learned in middle school physics that through a prism, the sun’s rays can be decomposed into seven colors visible

by our eye, red, orange, yellow, green, blue, and purple. In fact, there are at least hundreds of colors that cannot be clearly seen by eye.

 

We have produced various artificial light sources with different materials, functions, and characteristics, all of which use the sun

as a reference target, and most of the data are aligned with the sun’s rays. Among them, the color rendering index (CRI) index

commonly used by the International Commission on Illumination is a method to detect the quality of LED lights.

 

In the color rendering index (CRI) of LED lighting, 15 different color indicators are used to measure the light emitted by the light,

and R1–R15 is used to replace the description. The ability to restore the color of these 15 indicators (the data refers to the sun’s rays,

and the color rendering index of the sun’s rays is 100%) is used to illustrate the color reduction ability of the light.

Generally, it can be called full-spectrum LED lighting, which needs to meet at least 2 standards：

  1.  CRI index exceeds 95 or more
  2. In particular, the color rendering index of R9 (saturated red) and R12 (saturated blue) is at least 90

Therefore, the object itself refers to the color of the object when it is illuminated by sunlight in the daily environment. Sunlight is composed

of 7 colors of light visible to the naked eye. Taking sunlight as the benchmark, the more colored light contained in the white light of LED lamps,

the closer it is to sunlight, and the more it can restore the true color of the object.That is to say, the white light mixed with different kinds of lights

can provide light with rich color sense, which is highly reductive to the skin color of people and the natural color of objects without color cast.

 

What about the LED bead? The LED bead is actually a light-emitting diode with a bluish light, and different levels and color ratios of toner are added,

and the light is continuously mixed through the content ratio of the toner to output different colors. light effect.

 

Compared with ordinary led lights, the lights made of multi-color mixed light have stronger spectrum, wider color gamut and higher color accuracy.

This kind of multi-color mixed light undoubtedly has the real core competitiveness in terms of the domestic LED lighting market with mixed fish

and dragons. The full-spectrum technology formed by multi-color mixed light is also the core problem that various film and television live broadcast

lighting manufacturers need to solve urgently in the future.

 

At present, Except the well-known German brand – ARRI, which has six-color mixed light, there is also a large domestic company -NiceFoto Lighting,

which has also mastered the multi-color mixed light technology, which can directly mix red and green. Multi-color mixed light such as blue and yellow

forms white light or colored light of various colors. Whether it is the lighting effect or various lighting parameters, it has achieved a higher level of similar lighting.
