LLB BULB HAVING LIGHT EXTRACTING ROUGH SURFACE PATTERN (LERSP) AND METHOD OF FABRICATION |
摘要 |
A LLB bulb includes a base, a LED light source configured to emit electromagnetic radiation, and a lens/cover having a light extracting rough surface pattern (LERSP) configured to reduce glare and reflection in the LLB bulb without light loss. A method for fabricating the LLB bulb includes the steps of providing the lens/cover, and forming the light extracting rough surface pattern (LERSP) on the lens/cover. The lens/cover can be fabricated with the light extracting rough surface pattern (LERSP) using a process such as bead blasting, sand blasting, etching (chemical or plasma), or molding.
