Abstract:
Adopting the nanosized YAG (Yttrium Aluminum Garnet) phosphoras the raw material of a white LED lamp secondary encapsulation structure is able to form a surface light source,enhance euphoropsia,reduce the biological hazard,and solve the problems about excess blue light and glare.The as-prepared white LED lamp secondary encapsulation structure has good temperature tolerance and ageing resistance and provides an evaluation system for the optical conversion performance of the secondary encapsulation structure.
Key words:  white LED lamp secondary encapsulation  euphoropsia  photo biological hazard
