New description: [New technical field] The present invention relates to a white light emitting diode, and in particular to a white light emitting diode having high color rendering. [Prior Art] Light Emitting Diode (LED) is a tiny solid-state light source with small specific capacity, good shock resistance, power saving, long life and variety of colors. No need to use mercury. And with a variety of emerging application needs, has become a visible source of light in everyday life. Compared with traditional incandescent bulbs and fluorescent lamps, LEDs can be both energy-saving and environmentally friendly, and have been widely used in various lighting fields. Conventional white light-emitting diodes are mostly mixed with fluorescent light in the encapsulant. The sealant can fill the cavity of the light-emitting diode. The light-emitting diode chip in the cavity can emit blue light and excites, for example, YAG. The phosphor powder emits yellow light, and the blue light and the yellow light can be mixed to obtain white light. However, this method knows that the color rendering property (c〇l〇r rendering property) is low, because =, there is also mixed red fluorescent powder or green fluorescent powder in the encapsulant to increase the white light emission. The color rendering of the polar body, but compared to the yellow glory private 'red and green fluorescent powder' is less efficient, moisture resistance and resistance, and = no bauxite. In addition, the heat generated by the LED chip is finely divided by the encapsulant colloid which is in direct contact with the LED chip and the glory powder which is in direct contact with the LED chip, thereby affecting the efficiency and lifetime of the phosphor powder. Another type of white light emitting diode is a white light that is emitted by a red, blue, and green three-color chip that is commonly sealed by a wavelength of 5 M341939. However, because it is not easy to control, the color difference often occurs at the edge. [New content] == The new purpose is to provide a structure of white light-emitting 杈 group, in order to improve its color rendering. Body
