Abstract

The invention discloses a visible light communication LED driving modulation system based on Bluetooth regulation and control. The system comprises a power supply module, a voltage stabilization module, a control circuit module and an LED module. The power supply module is used for supplying power to the control circuit module and the LED module; the voltage stabilization module is used for performing voltage stabilization conversion on the voltage provided by the power supply module for the control circuit module; the control circuit module is used for acquiring and storing transmission data through Bluetooth, transmitting the transmission data and outputting an optical signal instruction; and the LED module is used for generating an optical signal according to the optical signal instruction and completing visible light communication LED driving modulation. According to the invention, stable white light illumination can be provided indoors, and meanwhile, the Bluetooth module is wirelessly controlled through a mobile phone terminal, so that an illumination and communication integrated function is realized.

Description

technical field [0001] The present application relates to the technical fields of visible light communication and LED lighting, and in particular to a bluetooth-based control and modulation system for LED drive and modulation of visible light communication. Background technique [0002] As a new type of wireless communication, visible light communication technology not only has lighting functions, but also has rich bandwidth resources and high security. At the same time, it is suitable for places sensitive to electromagnetic interference, which is of great significance. It uses LED as the information light source for the modulated information to send out a high-frequency flickering signal that is difficult for the human eye to propagate as an optical signal in free space, and uses a photoelectric conversion device to convert the received optical signal into an electrical signal, and then further Perform amplification, filtering and other processing, and then demodulate the e...
