Abstract

The invention discloses an LED lighting lamp identification method, a lamp, a verification device and a system. The method comprises the steps that S1, signature information of the LED lighting lamp is generated; S2, the signature information is modulated and transmitted in the mode of an optical signal via the LED lighting lamp; S3, the optical signal with the signature information is received, and the optical signal is converted into an electric signal; and S4, the electric signal is demodulated, the signature information is extracted and the signature information is identified or judged. The lamp comprises a control unit, an LED driver and an LED lamp. The verification device comprises a photoelectric conversion unit, a signal demodulation unit and a digital processing unit. The system comprises the LED lighting lamp and the verification device of the LED lighting lamp. Judgment of authenticity of the lamp is realized, and characteristics that optical signal transmission is not affected by electromagnetic interference and has no penetrability are utilized so that reliability and security of signature information transmission are realized. Besides, additional cost is not increased or only a small part of cost is increased. The LED lighting lamp identification method can be widely applied to various LED lighting lamp identification systems.

Description

technical field [0001] The invention belongs to the field of LED communication, and in particular relates to a method for realizing lamp identification through the light emitted by the LED lighting lamp itself. The invention also relates to an LED lighting lamp, a verification device for the LED lighting lamp and a system for identifying the lamp. Background technique [0002] PPM: pulse position modulation, using the modulation signal to control the relative position (ie phase) of each pulse in the pulse sequence, so that the relative position of each pulse changes with the modulation signal. [0003] The current authenticity identification technology and anti-repudiation technology mainly include laser anti-repudiation code, bar code (or two-dimensional code) and RFID anti-repudiation and so on. However, laser anti-repudiation codes and barcodes are very easy to be copied or require professional equipment to identify them. [0004] For the specific product of LED lighting...
