Problems solved by technology

[0003] Traditional silicone packaging materials mainly include methyl silicone and phenyl silicone. Methyl silicone has good heat resistance and UV resistance, but its refractive index is low, and the light extraction efficiency of LED is low. Due to its low hardness, it is resistant to vulcanization Poor performance; phenyl silica gel has high refractive index and high hardness, and has good light extraction efficiency and anti-vulcanization performance, but its temperature resistance and ultraviolet resistance are poor, it is prone to yellowing, and the light decays when it is lit for a long time

Description

technical field [0001] The invention belongs to the field of LED packaging, and in particular relates to a UV-LED packaging glue and a preparation method thereof. Background technique [0002] UV-LED is a kind of LED, which emits invisible light of a single wavelength, generally below 400nm. Compared with traditional mercury lamps, UV-LED has the characteristics of energy saving, less heat loss, long life, and concentrated wavelength. It is a new type of environmentally friendly light source and is widely favored by the market. At present, the packaging of UV-LEDs mainly follows the packaging method of white LEDs, and silicone resin is still used as the packaging material. However, due to the shorter wavelength and higher radiation energy of UV-LEDs, there are higher requirements for the performance of packaging materials. . [0003] Traditional silicone packaging materials mainly include methyl silicone and phenyl silicone. Methyl silicone has good heat resistance and UV ...
