As LED technology continues to evolve, so that made possible the LED as a light source, light source in lighting, color rendering index CRI has very strict requirements, the current white LED color is not very mature, making it the constraints LED as the lighting of the main obstacles.
White composite light, through the prism it is easy to break down the white light contains all colors of light. The LED street light bulb is a more comprehensive chromatography light laid a theoretical foundation, the characteristics of such a wide color gamut LED lighting products, high color rendering.
Light is a wave-particle two-phase material, a substance that contains the wave characteristics include the characteristics of the particles, so that it has a strong composite characteristics, so in terms of the nature of light and LED street light bulb characteristics, LEDs are becoming high-quality lighting possibility.
Current white led high bay technology, used mainly blue chips recoating phosphor production process, the technology developed by Nichia, fluorescent tubes emitting principle followed from a sense, this technology due to the red and green components missing, so that congenital defects on the color rendering index, the current to compensate for this defect, the main direction of the phosphor technology within the industry.
The blue chip coated with phosphor to the manufacture of white light technology, this technique can in principle produce better white, but weaker ability to adapt to the environment during use, resulting in a theoretical and practical differences, such the differences are largely generated by the LED heat accumulated temperature impact on the phosphor.
