ABSTRACT:
An alarm clock of the analog type with hands for indicating the time includes a battery, a housing, a dial with time indicia disposed in the housing and an illumination module disposed adjacently to the dial. The illumination module has one or more recesses defined in an edge with one or more light sources disposed in the recesses to provide illumination into the module. The illumination module has edges and a back surface with light reflective properties to reflect light in the interior of the module and out the front surface and through the dial to provide night lighting exterior to the clock. Preferably, the module has an ovate shape such that the recesses and light sources are disposed outside of the dial area. A light sensor senses the ambient lighting conditions and activates and deactivates the light source. A dimmer control adjusts the desired level of illumination. A three position switch controls the alarm clock between alarm only, night light only, and both alarm and night light modes of operation.
