Abstract
A lamp component has a support with a base surrounded by an interior wall defining a cavity with a central axis. A plurality of LEDs are supported on the interior wall and generally aimed to direct light towards the central axis. A center piece has a first reflective surface shaped and positioned to intercept light received from the LEDs and reflect such received light generally in a direction parallel to the axis.
