CONCATENATED LIGHT PIPE

Abstract

An illuminated assembly such as an illuminated electronic input control assembly adjusts to the shape of a receiving assembly. The illuminated assembly includes an illumination source module and an illuminated module. Advantageously, the illumination source module and the illuminated module are moveably attached in a manner allowing relative motion which facilitates alignment when the illuminated assembly is placed within a receiving assembly. A garage door opener utilizes this adjustable design. A method of assembling the illuminated assembly is described.
