Currently, rare earth cerium-activated yttrium aluminum garnet structure with a blue LED with yellow phosphor to produce white light emission efficiency mode is best, however, since the light-emitting phosphor in the red part of the serious shortage of white LED products resulting color is poor We can not take advantage of the single fluorescent powder low color temperature, high color rendering white LED. This "blue chip gluten products as the light source, the visual feeling too cold; as the LCD backlight, display color gamut is narrow, full-color effect is not good use." Pink yellow powder produced by blue-chip white LED display device index Notwithstanding the substantial increase (80 and over), but to show a higher index (90 or more), you must join the green phosphor. First, while not using phosphors (colorful powder) can be prepared by red, different colors of yellow, green, blue, purple and other color phosphors LED solvent, but because of these different color LED luminous efficiency vary widely, using fluorescent After the meal, others may be prepared to take advantage of some of the bands LED band high LED luminous efficiency, in order to improve the luminous efficiency of the band. Secondly, LED emission wavelength is still difficult to precisely control, which may cause some wavelengths of LED applications appear not waste fluorescent paint, for example, require the preparation of 470nm when the LED, it is possible to prepare from 455nm to 480nm range wide LED, Illuminating wavelength across the LED can only lower prices or dispose of the waste, and the use of phosphors can use these so-called 'waste' transformed into color and we need to get used. Third, after the use of phosphors, some LED light color will become more soft or bright, to meet different application needs. Of course, LED phosphors in the most widely used in the field or in the white phosphor technology, but because of its unique advantages phosphors in color LED can be obtained in certain applications, but the phosphors used in color LED has just It started, the need for further in-depth research and development.
