Remote controlled led based id emitter

Abstract

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.
