| 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 |
