Abstract
A LED light bulb (10, 110, 210) having at least one LED (30a-d, 230). Light output from the LED is directed toward an offset scattering optics structure (50, 150, 250) that intersects and scatters the light output. The LED may optionally be paired with a narrow beam optical piece (32a-d, 132a-d, 232) to focus and direct the light output of the LED toward the scattering optics structure. A mounting structure (40, 140, 240a, 240b) may support the scattering optics structure and offset the scattering optics structure from the LED.
