Lighting device operating at different power levels
First Claim
1. A lighting device comprising:
- a plurality of light sources comprising a first set of one or more light sources and a second set of one or more light sources, the first set of one or more light sources configured to be powered by direct current, the second set of one or more light sources configured to be powered by alternating current;
electronic circuitry comprising a sensor that determines activity of an individual and a microprocessor operably coupled to the sensor; and
a housing encompassing the first set of one or more light sources, the second set of one or more light sources, and the electronic circuitry, the housing configured to be electrically combined with a ballast prefixed in a light fixture to power the first set of one or more light sources and configured to be removably fitted into the light fixture, the microprocessor configured to power the second set of one or more light sources upon the detection of the activity of the individual.

Abstract
The current subject matter relates to a lighting device that can be installed in an already existing fixture in a structure. The lighting device can include a light emitting diode (LED) lighting segment and a fluorescent lighting segment. The LED lighting segment can include a LED lighting source, and the fluorescent lighting segment can include a fluorescent lighting source. The LED lighting source can be activated. Motion sensors and/or occupancy sensors can detect motion and/or occupancy of an occupant in the structure. If there is motion or if the occupancy is more than a predetermined threshold, the fluorescent lighting source can be activated. After each regular interval of time, the detection of motion or occupancy can be re-performed. If there is no detection of motion and/or occupancy, the fluorescent lighting source can be deactivated, after a period of time. Related apparatus, systems, techniques and articles are also described.

10. A method comprising:
-
electrically combining a lighting device with an instant start ballast prefixed in a lighting fixture without modifying the lighting fixture, the lighting device comprising; a plurality of light sources comprising a first set of one or more light sources and a second set of one or more light sources, the first set of one or more light sources and the second set of one or more light sources configured to power at different electrical input values; electronic circuitry comprising a frequency sensor that determines an activity of an individual and a microprocessor operably coupled to the frequency sensor, the electronic circuitry further comprising a transformer configured to operably couple with the instant start ballast; and a housing encompassing the one or more light sources and the electronic circuitry, the housing configured to be electrically combined with the instant start ballast prefixed in the light fixture to power the first set of one or more light sources and configured to be removably fitted into the lighting fixture, the microprocessor configured to power the second set of one or more light sources upon the detection of the activity of the individual; and communicatively coupling the microprocessor with a server via a communication network, the communicative coupling enabling the server to remotely vary dimming luminosity of at least one of the first set of one or more light sources and the second set of one or more light sources. - View Dependent Claims (11, 12)
