Abstract

There is provided a system of controlling product display lighting capable of controlling brightness levels and/or colors of illuminating light suitable for corresponding products according to characteristics of products, such as kinds or colors of products. The system of controlling product display lighting may include an information input unit acquiring information on products; a coordinator determining brightness levels and colors of illuminating light provided to the products according to the information on the products; a light source driver generating light source driving signals for outputting the determined brightness levels and colors of illuminating light in the coordinator; and a light source unit outputting illumination light having the brightness levels and colors of illuminating light determined in the coordinator by the light source driving signals.

Claims

1. A system of controlling product display lighting, comprising:

an information input unit acquiring information on products;

a coordinator determining brightness levels and colors of illuminating light provided to the products according to the information on the products;

a light source driver generating light source driving signals for outputting the determined brightness levels and colors of illuminating light in the coordinator; and

a light source unit outputting illumination light having the brightness levels and colors of illuminating light determined in the coordinator by the light source driving signals.

2. The system of controlling product display lighting according to claim 1, wherein the information input unit includes:

a camera module generating color images of the products;

a display unit displaying the color images of the products and providing them to the user;

a user input unit receiving the information on the brightness levels and colors of illuminating light applied to the products from a user referring to the displayed color images; and

a radio communication module transmitting the information of brightness levels and colors input from the user input unit to the coordinator as the product information.

3. The system of controlling product display lighting according to claim 2, wherein the coordinator includes:

a radio communication module receiving the information of brightness levels and colors received from the user input unit; and

a lighting controller determining the brightness levels and colors of illumination light output from the light source unit according to the information on the brightness levels and colors received from the user input unit.

4. The system of controlling product display lighting according to claim 1, wherein the information input unit includes:

a camera module generating the color images of the products; and

a radio communication module transmitting the color images of the products to the coordinator as the product information.

5. The system of controlling product display lighting according to claim 4, wherein the coordinator includes:

a radio communication module receiving the color images of the products;

an image analyzer analyzing the color images of the products to generate the information on the brightness levels and colors of illuminating light to be provided to the products; and

a lighting controller determining the brightness levels and colors of illumination light output from the light source unit according to the information on the brightness levels and colors of illuminating light generated from the image analyzer.

6. The system of controlling product display lighting according to claim 1, wherein the information input unit includes:

an RFID reader or a barcode reader reading RFIDs or barcodes applied to the products to acquire the information on the products; and

a radio communication module transmitting the information on the products acquired from the read RFID or barcode to the coordinator.

7. The system of controlling product display lighting according to claim 6, wherein the coordinator includes:

a radio communication module receiving the information on the products;

an image analyzer analyzing the information on the products to generate the information on the brightness levels and colors of illuminating light to be applied to the products; and

a lighting controller determining the brightness levels and colors of illuminating light output from the light source unit according to the information on the brightness levels and colors of illuminating light generated from the image analyzer.

8. The system of controlling product display lighting according to claim 1, wherein the light source unit includes at least one red LED, at least one green LED, and at least one blue LED, and

the light source driver includes a red LED driving circuit for driving the at least one red LED, a green LED driving circuit for driving the at least one green LED, and a blue LED driving circuit for driving the at least one blue LED.
