ABSTRACT:
A conventional lamp having a tubular yoke around the bulb that supports a lamp shade is converted into a security system by a simple physical electrical and mechanical coupling of two modules, eliminating wiring and installation tools. The first module, referred to as the bulb module, is screwed into the bulb socket and contains line voltage components and supports the light bulb; the second module, the probe module, contains low voltage circuitry, an audio alarm, a pigtail power connector, a light switch, and an extendable sensor probe. Upon sensing an abnormal condition, such as smoke, the bulb flashes on and off and a warning sound is provided by the audio alarm, giving both visual and audio alarm in one self-contained unit.
