Abstract: A novel illumination device is provided which is small, inexpensive, and conveniently plugs into a standard power outlet, thereby allowing easy installation and deinstallation by nontechnical consumers, and thereby allowing the security light to be easily moved to any wall outlet as security needs change. This illumination device includes a motion detector so that the illumination is provided only in the presence of one or more persons who would find the illumination beneficial. A photoelectric device is provided such that the security light is illuminated in response to motion only when there is an insufficient amount of ambient light available from other sources. In one embodiment, a vision restrictor is provided such that motion is detected only from a desired detection area. In one embodiment, a vision extender is utilized in order to optimize the field of view for the motion detector, making the device more useful in narrow hallways and other unique installations.
