Abstract: A lamp having a candle-like appearance and using one or more light-emitting diodes (LEDs) as its light source is presented. The candle-like appearance arises because light is emitted from only a small volume at or near the center of the bulb. The heat sink and control electronics are located outside the bulb of the lamp. Inside the bulb is a set of secondary optics that guide the light from one or more LEDs to an emission point at a prescribed location in the interior of the bulb. The secondary optics include a light pipe that guides light away from the LED chip, and a volume scattering element that receives the light from the light pipe and scatters it into various directions. The volume scattering element is made from a transparent base material, and includes transparent particles of a predetermined size and refractive index.
