Abstract
A light source particularly suited for a display in a dispensing machine. The light source includes an array of light emitting diodes (LEDs) mounted on a printed circuit board (PCB) with a multi-directional, multi-functional reflector disposed about the PCB. The reflector reflects the LED light in multi-directions and serves to provide a more uniform light intensity throughout the illuminated surface. The reflector also encloses the total light radiation to a pre-defined surface area.
