Abstract
A light bulb includes a light emitting device at the base of the bulb and a light guide () that guides the emitted light to a diffusion element () above the base of the bulb. The diffusion element is configured to diffuse the light so as to emulate the predominantly radial light distribution pattern produced by a candle. A variety of features for the diffusion element, as well as features of the base and bulb, are presented that enhance the candle-like effects.
