An LED lamp

Abstract

The invention relates to an LED lamp. The LED lamp is characterized by in that: the LED lamp comprises an LED lampholder and an optical transmit-receive module connected with an LED module; the optical transmit-receive module is connected in a branching mode with a circuit board; the circuit board can be externally connected with a fiber or an electric power carrier wave wire PLC, and / or the optical transmit-receive module is integrated into a branching arrangement circuit design; a branching arrangement circuit is connected with a wireless module; and the LED lamp also comprises a power supply. The optical transmit-receive module, and / or the branching arrangement circuit are arranged on the LED lampholder. The LED lampholder is externally connected with the power supply. The optical transmit-receive module and / or the branching arrangement circuit realizes mutual wireless-optical data exchange or light-wireless data exchange through A / D sampling data recovery in an LI-FI visible light network; or the optical transmit-receive module or / and a radio frequency chip-a base-band chip of the branching arrangement circuit realizes exchange identification of MAC frame data in a same LED lamp through a network bridge technique and further realizes mutual wireless optical data exchange or light-wireless data exchange in the LI-FI network.

Description

technical field [0001] The present invention relates to an LED lamp. The LED lamp of the present application is a carrier applied to Li-Fi (Light Fidelity) or VLC (Visible Light Communication) data processing. Background technique [0002] <<Jiangsu University Master's Degree Thesis>>2008 (Classification No. TN929, No. 102990608130, UDC Note 1:621.396) <<Analysis and Design of Wireless Optical Communication System Based on LED Traffic Lights>>Chapter 1 Introduction Section 1.2 Research Status at Home and Abroad And difficulties, cited on page 5: G Pang et al. of the University of Hong Kong first proposed the use of LED traffic lights to transmit voice broadcast signals for vehicles in 1999, and analyzed the feasibility of visible light communication [20]. By establishing a model, performing OOK modulation on the current and adding it to the LED light source, low-speed wireless LED visible light communication is realized. However, this research was pr...

Problems solved by technology

[0007]The applicant noticed that: and in a specific environment, wireless communication or visible light communication technology still has certain deficiencies: for example, when passing through a tunnel, the wireless signal is dropped , On the one hand, the signal is full, on the one hand, only the voice of the other party can be heard, and the voice of the other party cannot be received by the other party, or the other party can hear the voice of the other party, but the voice of the other party cannot be heard; on the other hand, special Due to the application environment of visible light, the LED light of the data carrier of visible light suddenly goes out, and the possibility of using optical frequency code to transmit data is lost, such as power failure
