Abstract
A light pipe assembly (10) for an electrical device comprises a holder (12) made of a compliant material, and light pipes (14) which transmit light. The light pipes are seated in channels (16) formed in the holder. The holder has compressible ridges (22) formed on the portion of the holder where light enters (18). The light pipe assembly is seated in the device such that the light receiving face (34) of each light pipe is in proximity to a surface mounted LED (50). The compressible ridges keep light from bleeding from the LED to adjacent light pipes and compensates for the slight variations in dimensions between the housing (42) and the circuit board (44) of the device. The top portion (30) of each light pipe protrudes above the holder and through openings in the housing so that the signal of the LED can be seen.
