Abstract:
A pear-shaped light-emitting diode (LED) light bulb housing is provided with a plurality of light-dispersing thickness variations in the bulb envelope. Dimples, bumps, or v-shaped grooves are provided in a middle portion of the bulb envelope in order to uniformly disperse light from LEDs as the light passes through the bulb envelope.
