Abstract
A segmented display includes a first housing portion having graphic openings therein, a second housing portion spaced apart from the first housing portion and a first circuit board comprising a plurality of light emitting diodes (LEDs). The first circuit board is disposed between the first housing portion and the second housing portion. A first side wall and a second side wall are spaced apart from the first side wall. The first side wall and the second side wall define a plurality of photon recycling cavities in a sequence wherein adjacent photon recycling cavities having a shared end wall. At least one of the LED is disposed in each of the photon recycling cavities. Each LED is associated with an optical element redirecting light within the associated cavity so that light from the light emitting diode is indirectly communicated through the graphic opening after reflecting within the photon recycling cavity.
