Abstract

The invention relates to a data tag (6, 21, 32) storing at least one setting (13, 43) for controlling one or more lights (4, 18, 29). There is also provided a system and method for controlling a plurality of lights by receiving information (43) indicative of lighting settings for the plurality of lights (18, 29) from a data tag (21, 32) and controlling the plurality of lights (18, 29) in accordance with the lighting settings.

Claims

1. A lighting unit comprising:

a data tag reader linked to a command converter and a lighting control interface, the lighting control interface connected to a set of LEDs, the command converter wirelessly linked to a computer system, the computer system linked to a remote database residing via an internet connection;

a first database residing in the command converter and storing information about the set of LEDs;

a second database residing in the command converter and storing information for mapping data contents of data tags to lighting settings; and

the data tag reader configured to detect data contained in a data tag and transmit the data to the command converter, the command converter searching the first and second databases upon receipt of the data and generating a lighting setting signal to the lighting control interface for controlling the set of LEDS in accordance with the information in the first database and the mapped settings in the second database, wherein the computer system provides updated data from the remote database to the second database, wherein the data tag is a radio-frequency identification(RFID) tag and the data tag reader is a RFID reader.

2. The lighting system of claim 1 wherein the information for mapping data contents of data tags to lighting settings is selected from the group consisting of product type, product class product price, product collection, product style, time a given product has spent on a shelf, and number of times a product is moved.

3. The lighting system of claim 1 wherein the lighting control interface operates according to a DMX, DALI, ZigBee, LON works, Konnex or BACnet protocol.

4. The lighting system of claim 1 wherein the data in the data tag comprises lighting settings selected from the group consisting of a color lighting setting, an intensity lighting setting defining an intensity of light to be produced, a light directivity lighting setting defining a direction to which light produced should be emitted, a selection of a subset of lights lighting setting from a plurality of lights, a beam angle lighting setting, a spot light lighting setting, a diffuse light lighting setting, an ambient light lighting setting, and a dynamic characteristics lighting setting for the one or more lights.
