Abstract:
Alight emitting diode light bulbs (LLB) bulb (10A) includes a base (12A),a light emitting diode (LED) light source (16A) configured to emit electromagnetic radiation, and a lens/cover (18A) having a light extracting rough surface pattern (20) (LERSP) configured to reduce glare and reflection in the LLB bulb (10A) without light loss. A method for fabricating the LLB bulb (10A) includes the steps of providing the lens/cover (18A), and forming the light extracting rough surface pattern (20) (PERSP) on the lens/cover (18A). The lens/cover (18A) can be fabricated with the light extracting rough surface pattern (20) (LERSP) using a process such as bead blasting, sand blasting, etching (chemical or plasma), or molding.
