Abstract
A translucent cover for an LED light bulb is disclosed. The translucent cover includes a cover body made from a light-transmissive material, light-scattering particles in the light-transmissive material, and a series of micro-structure features on and inner surface of the cover body. The micro-structure features are configured to refract and reflect light emitted from the LED light bulb to increase the emission angle of the light emitted from the cover.
