System for identifying ID (identity) information of lamp by white light of LED (light-emitting diode)

Abstract

The invention relates to a system for identifying ID (identity) information of a lamp by white light of an LED (light-emitting diode). The system comprises a transmitting part and a receiving part, wherein the transmitting part comprises an information unit module which is used for transmitting the ID information of the lamp to an information encoding and modulation circuit module; an LED driving power supply module is used for transmitting constant current to a current control circuit module; the information encoding and modulation circuit is used for performing numbering and modulation on the information transmitted by the information unit module, then outputting a control signal and transmitting to the current control circuit module for further control of the output current of the current control circuit module; the LED power supply is used for receiving a current signal output by the current control circuit module and converting the current signal to an optical signal; and a photoelectric detection circuit module is used for receiving the optical signal of the LED lamp and converting the optical signal to an electric signal, and the electric signal is output after signal analysis processing and decoding by a decoding circuit module. The structure can be applied in a dark environment or an environment with single background light, and can be used for monitoring the state of a light source or positioning a mobile lamp and the like.
