The Higher LED Light Effect, The Lower The Color Index?
Jul 01, 2017

The higher LED light effect, the lower the color index?

The higher the LED light effect, the lower the color index is. This is obviously not true. First of all, the causal relationship of this logic is somewhat counteracting, not because it is low in light, but in order to increase the explicit meaning and sacrifice some light effect. However, there are some misunderstandings about the cognition of light effect.

Now available LED, mostly on blue LED chip coating can be excited by blue light (YAG) yellow phosphor, we usually call yellow powder, blue with yellow light from fluorescent powder from the chip complementary to form white light.

If you want to improve the color of the LED, you need to involve the calculation of the color index. In general, the color index is calculated as r1-r8, which is relatively narrow.

But it's also missing a very important spectrum, which is specifically referred to as R9, red R9 (saturated red;) It is the index to evaluate the quality of red reproduction. For their application, the studio, the studio and so on need to be real to reproduce the skin color of the occasion, and the color reduction of the raw meat of fruits and vegetables has an irreplaceable role.
