Abstract
The alarm clock includes a strongly illuminated dial from which an image is projected onto the ceiling or a wall of the bedroom, so that it can be seen without the user needing to move. The dial may be illuminated by transmitted light or reflected light from one or several small lights deriving power from batteries or the mains. An optical system consisting of several lenses of glass or other transparent material focusses the image on a chosen surface. A switch is provided to turn on the projection light, although the light may also be turned on by an electrical contact associated with the alarm.
