Abstract
A remote control including a plurality of function indicators made of a semitransparent material that allow light to pass through, a light source, and a light pipe placed behind the function indicators, the structural combination allowing the remote control to be operated in a darkened room. The structural combination is a layered arrangement of a printed circuit board that includes a group of light-emitting-diodes functioning as the light source, a number of function indicators arranged in one flexible layer, and a light pipe which is sandwiched between the printed circuit board and the layer of function indicators. The light pipe is made of transparent plastic and includes a group of bevelled recesses to receive the group of light-emitting-diodes, thereby distributing the light emitted by the light-emitting-diodes uniformly.
