Abstract
Disclosed is a touch-programmable lighting and security device in the form of a stand lamp which can be programmed to provide illumination by means of an AC bulb or DC bulb in conjunction with parameters including the ambient light level, presence of people, and AC mains power failure. In one embodiment, this novel lighting and security device includes a transmitter which transmits an Alarm signal to a remote receiver upon detection of an intruder. This user friendly device conveniently plugs into any wall power outlet by means of a suitable length of cable and it can be easily programmed by touching different nonmetallic areas of the device. In one embodiment, four indicator lights in the form of LEDs are provided to identify its prevailing mode.
Claims13
A control for electrically energizing an illumination means, said control having:
- input means for connection to a source of electrical energy,
- output means for connecting electrical energy from the control to said illumination means,
- a first means to detect the presence of moving infrared radiation sources,
- a second means to compare the level of ambient light with a preset threshold, and
- a third means to electronically override the said first means and said second means;
- said control having modes of operation which comprise:
- a first operation mode wherein said output means is energized upon the detection of a moving infrared radiation source and remains energized for a predetermined period of time after cessation of said detection, provided the ambient light intensity is below a predetermined level,
- a second operation mode wherein said output means is energized when the ambient light intensity is below a predetermined level regardless of detection of a moving infrared radiation source, and
- a third operation mode wherein said output means is energized regardless of detection of a moving infrared radiation source or ambient light level, wherein each of said operation modes is controlled by a signal generated by a proximity sensor.
