The nature of the lighting is while, according to Ming, the light shines in the object, and objects into the eye after reflection, so the process of lighting objects on the various wavelengths of light absorption is different, and thus a solid color of red, green and blue color LED 3:6:1 mix of light and out of the white light itself there are certain color defects, exposure to the surface, absorbed on the surface of the red, green and blue, was an object, the reflection effect caused by CRI reduction.
Tricolor RGB led downlight color mixing technology is a more mature white lighting technology, this technique because the larger the distance between the different led high bay light mixing distance, before the LED plus mixed mask, to solve the mixed light problem, but the light loss is an obstacle to the development of lighting toward the thin obstacle. Again to watch the lighting is not uniform white; of these two factors directly restricts the development of this technology.
Based on the tricolor RGB led downlight mixed light technology to solve two issues started. The study found that as the distance between the LED chip to reduce the mixing of light from the decrease exponentially with increasing bulk reagent concentration in the surface coating of color mixing is exponentially enhanced, in depth study of the commencement of find an optimal balance between the three color LED chip spacing reduction and three-color reagent concentration increased, a solution the best solution of the three primary colors mixed with light, this program so that the tricolor white LED as a light source made possible.
