Abstract (en)
The present invention is related to a control panel and in particular to remote controls equipped with a backlight system. The backlight system comprises at least one laser diode as light source and mirrors or other beam splitting elements to direct portions of the laser light to operating keys of the remote control. The use of a laser diode and deflecting elements provides a very efficient backlight system reducing the energy consumption and thereby enhancing the battery lifetime of a remote control. The remote control according to the invention also allows new design opportunities. <IMAGE>
