Abstract
A light barrier and/or light reflector for PCB-mounted LED's has reflective walls defining interior chambers which redirect the light from the LED's in a substantially orthogonal direction and shield each LED from the light emitted by adjacent LED's. The device is particularly suited for redirecting light from LED's on a PCB to a status indicator panel thereby replacing conventional light pipes.
