JSR has developed a high refractive index coating material which can improve the luminous efficiency of LED

JSR has successfully developed a high refractive index coating material that can improve the luminous efficiency of high brightness light-emitting diodes (LED), and the new packaging materials necessary to improve the reliability of LED. The company's original coating material refractive index of about 1.7. Newly developed high refractive index coating material reached about 1.9. According to the company, said in the user evaluation, has been confirmed in the LED light-emitting devices on the coating of the new material, LED luminous efficiency can be increased by more than 10%. The company said that the luminous efficiency is expected to improve the realization of LED long life and energy saving. On the other hand, the new packaging materials are made of organic-inorganic hybrid transparent resin. Through the company's unique synthetic technology of organic and inorganic hybrid materials, it has the advantages of organic material flexibility and high heat resistance and reliability of inorganic materials. Epoxy resin and silicone resin are the mainstream of LED packaging materials, but the former has the disadvantages of heat resistance and light resistance, and the latter has the disadvantages of insufficient air tightness. The company said that the new packaging materials are expected to be used in lighting and lighting lamps and other requirements of high heat resistance and durability of the field.
