Flood light lamp removal alarm
First Claim
1. A flood light lamp removal alarm assembly for home security flood light fixtures having at least on one socket accommodating at least one flood light lamp, said socket connected to a power supply for the lamp, the fixture having a low ambient light detector and a motion detector, wherein the assembly detects unwarranted unscrewing of the flood light lamp therefrom, comprising:
- a housing containing a perceptible alarm;
a means for detecting removal of the lamp, said means comprising the lamp socket having a physical condition sensor therein, which physical condition sensor is inactivated when said lamp is properly screwed into said socket, said physical condition sensor being activated when the lamp is loosened or removed from the socket;
said sensor comprising a switch mounted in the bottom of said socket positioned in such a manner that when said lamp is properly screwed into said socket, said switch is depressed in the closed position;
an electrical circuit means being connected to said switch for triggering said alarm when said switch is released as a result of loosening or removal of said lamp from said socket, said alarm remaining inactive as long as said switch remains depressed by said lamp; and
,said socket being provided with resilient electrical contact means for maintaining lamp-illuminating electrical contact during a partial removal of said lamp from said socket, while providing for said triggering of said lamp removal alarm even while said partially removed lamp remains illuminated by electrical contact with said resilient contact means.

Abstract
A flood light lamp removal alarm for security lights mounted on or near a home, wherein the lights are designed to turn on automatically if a motion detector is triggered and the ambient light level is low, detects if any of the flood light lamps are unscrewed or loosened, either prior to a burglary or during the attempt to disable the flood light assembly. A central contact of a lamp socket is modified so that it maintains contact with the lamp therein for a longer distance as the lamp is unscrewed out, so that the alarm is triggered before the light from the lamp is disabled. Alternatively, current detectors verify when a lamp is loosened from a socket by detecting changes in current draw across the socket.
