Description

Addressing system of LED lighting lamp

Technical Field

The invention belongs to the technical field of illumination, and particularly relates to an addressing system of an LED illumination lamp.

Background

Visible light communication is used for transmitting information by utilizing high-speed bright and dark flashing signals which are emitted by visible light such as a light emitting diode and cannot be detected by naked eyes, and most of common visible light signal transmission is that the visible light signals are transmitted through a monochromatic LED, and a photodiode intercepts light signals emitted by the monochromatic LED.

In a control system of a plurality of LED lamps, each LED lamp sets a unique ID (Identity) in the control system, but when these lamps are installed in a certain building, we cannot accurately know the ID of a certain lamp because the control system controls by identifying the ID of the lamp, and thus cannot control the parameters of the lamp.

The common solution is to search all lamps and their IDs on the system and then use the controller to find the actual locations of the lamps corresponding to these IDs, which is inefficient, especially in view of the inaccessible scenes.

Chinese patent application No. 2017107190551 discloses a pairing method for one-way visible light communication, and the system composition of the scheme is complicated, and only one-way communication of visible light can be realized, which has great limitations.

Therefore, there is a need to develop an addressing system with simple system design and high recognition accuracy.
