  For the overall consideration of technology,performance and cost,blue LED chip + phosphor is the best technique for lighting,because of its high technical maturity and relatively low cost.Among them,phosphor is the key factor for the luminous efficiency and color temperature,especially for the color rendering index of LED device.During 2014,the technique and market of LED phosphor is now getting a radical change.It is becoming a new developing trend in LED industry,that blue LED chip stimulate green and red phosphor for achieving light devices with its Ra higher than 80,and that LED back light cover more than 80% of the NTSC color gamut which can be used in LCD (liquid crystal display).It is also taken into reality that price of phosphors begins declining rapidly.
