Abstract
A lightpipe system for transferring light from light sources on a printed circuit board (PCB), such as light-emitting diodes (LEDs), to a display includes modular lightpipes coupled together. Each modular lightpipe couples to an adjacent modular lightpipe to form an integrated lightpipe system. All or selected numbers of the lightpipes may include detachable tabs, proturbances, pegs, or other structures to ensure proper alignment of the lightpipe system and attachment of the lightpipe system to the PCB.
