摘要:
Apparatus including a light emitting diode; a constant current source for driving the diode; modulation circuitry for modulating the current supplied to the light emitting diode so that digital information can be carried on light from the diode; and a filtering circuit between the constant current source and the light emitting diode to minimize the effect of LED modulation on the current source. Alternatively, the constant current source can supply current to the diode or to one of a power dissipating element or power storage element. A method for powering a light emitting diode includes using a constant current source; and modulating the current supplied by the constant current source at a frequency for transmitting digital data on light produced. In the alternative, a method can also include diverting current from the constant current source away from the light emitting diode, when the light emitting diode is not emitting light.

摘要:
A system and a method in which the location of a receiver with a rolling-shutter based camera, typically on a mobile device, is determined with respect to the known positions of one or multiple VLC emitting sources. The positioning information can be used in the context of an encompassing system that leverages the precise position of the receiver to serve contextual information to an application on the mobile device acquired from a remote system. The method of analyzing acquired data is also disclosed. The data can be digitally encoded in base 3, wherein a duty cycle of eighty percent on and twenty percent off maintains a constant brightness, and each digit divides an on portion into two pulses of different lengths. A computer readable non-transitory storage medium storing instructions of a computer program, which when executed by a computer system results in performance of steps of the methods.

An adapter for connection between a luminaire and a power input for powering the luminaire comprises circuitry for modulating light output of the luminaire to contain information, or circuitry for connection to a network so that signals associated with the luminaire are communicated on the network. The adapter is placed between the luminaire and a power input for the luminaire. Methods are provided for registering and establishing communication between a gateway device and a management platform, and for registering a luminaire device with the gateway so that it can be managed by the management platform. Portions of the larger system that constitutes the remote controlled lighting system are also described, including connected wall switches, sensors, and the gateways themselves.

An apparatus includes a luminaire; power input for the luminaire; a modulation circuit for modulating the power input so that light output includes an identifier of the luminaire; and a programmable memory for storing at least one of the identifier of the luminaire and a modulation scheme for modulation of the luminaire to place a signal on the light. A method for modulating light includes storing in programmable memory an identifier for the luminaire, the identifier being used to modulate the light, and/or a modulation scheme for modulation of the luminaire; and changing content of programmable memory to change the identifier and/or the modulation scheme. A method of efficiently deploying the luminaires and identifying their locations to a network is disclosed. A method of multi-factor authentication using authentication data transmitted by modulating the light emitted by a luminaire is also disclosed.
