Abstract
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.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
66 words
A security light comprising: a source of illumination; pronged plug means for insertion into a standard electrical wall outlet without the need for permanent electrical connection to power mains or permanent physical attachment to a structural support; means for detecting motion in an area near said security light; and means for applying power to said source of illumination in response to the detection of said motion.
Claim 2
Dependent Claim
66 words
A security light comprising: a source of illumination; pronged plug means for insertion into a standard electrical wall outlet without the need for permanent electrical connection to power mains or permanent physical attachment to a structural support; means for detecting motion in an area near said security light; and means for applying power to said source of illumination in response to the detection of said motion.
Claim 3
Dependent Claim
33 words
A security light as in claim 1 which further comprises: means for detecting ambient light; and means for disabling said means for applying power in response to a predetermined amount of ambient light.
Claim 4
Dependent Claim
16 words
A security light as in claim 1 wherein said motion detector comprises an infrared motion detector.
Claim 5
Dependent Claim
26 words
A security light as in claim 1 which further comprises means for selecting the area near said security light within which motion is to be detected.
Claim 6
Dependent Claim
36 words
A security light as in claim 4 wherein said means for selecting comprises a faceplate which selects one of a plurality of areas depending on the orientation of said faceplate with respect to said security light.
Claim 7
Dependent Claim
28 words
A security light as in claim 4 wherein said selected area is such that motion by a sleeping person is not detected while motion by others is detected.
Claim 8
Dependent Claim
34 words
A security light as in claim 1 which further comprises means for selecting a desired amount of time during which power is applied to said source of illumination, after motion is not longer detected.
Claim 9
Dependent Claim
28 words
A security light as in claim 2 which further comprises means for disabling said means for detecting ambient light when power is applied to said source of illumination.
Claim 10
Dependent Claim
40 words
A security light as in claim 1 which further comprises means for disabling said means for detecting motion when said means for applying power to said source of illumination causes power to said source of illumination to be switched off.
Claim 11
Dependent Claim
23 words
A security light as in claim 1 which further comprises means for adjusting the field of view of said means for detecting motion.
Claim 12
Dependent Claim
54 words
A security light as in claim 10 wherein said means for adjusting comprises: a fresnel lens for receiving infrared radiation and directing said infrared radiation to an infrared detector; and one or more movable reflective surfaces for directing infrared radiation received from a desired direction and reflecting said infrared radiation to said fresnel lens.
