Abstract
An LED lamp that includes a housing forming an open cavity, a plurality of LEDs configured to produce a light output disposed in the cavity, a lens disposed over the LEDs for focusing and/or diffusing the light output, and a redirection shield disposed in the cavity. The redirection shield includes a base plate with a plurality of apertures formed therein, and a plurality of shielding plates extending from a top surface of the base plate. The LEDs extend through the apertures. The shielding plates block a portion of the light output such that an overall light distribution of the light output from the LED lamp is asymmetric.
