Abstract

Disclosed are a lighting device, a lighting system including the same, and a method of operating the same. The lighting device includes a communication unit receiving contents through communication with an outside, a content analyzing unit detecting an output state of the contents by analyzing the contents received through the communication unit, a storage unit storing information of a driving condition of a lighting unit corresponding to the output state of the contents, a controller extracting the information of the driving condition of the lighting unit corresponding to the detected output state of the contents from the storage unit and allowing the lighting unit to operate according to the contents based on the information of the driving condition of the lighting unit, and a lighting unit driver outputting a driving signal used to drive the lighting unit according to a control signal of the controller.

Claims

1. A lighting device comprising:

a contents receiving unit receiving contents from an outside source;

lighting units comprising a first lighting unit and a second lighting unit; and

a controller controlling a first switching sequence of the lighting units and a second switching sequence of the lighting units based on a frequency, a tempo, and an intensity of an audio signal included in the contents and allowing the lighting units to sequentially drive according to the switching sequences;

wherein the lighting units are physically separated from the contents receiving device;

wherein the controller controls the first switching sequence of the lighting units by switching the lighting units on or off, separately, and the second switching sequence of the lighting units by switching the lighting units on or off, together;

wherein the second lighting unit is turned off by the first switching sequence when the first lighting unit is turned on; and

wherein the controller further controls the brightness of the lighting units based on the frequency, the tempo, and the intensity of the audio signal included in the contents.

2. A method of operating lighting units, the method comprising:

receiving contents transmitted from an outside source;

detecting an audio signal included in the contents;

determining a first switching sequence and a second switching sequence of the lighting units according to the contents based on a frequency, a tempo, and an intensity of the audio signal included in the contents;

driving the lighting units according to the first switching sequence and the second switching sequence; and

controlling the brightness of the lighting units based on the frequency, the tempo, and the intensity of the audio signal included in the contents;

wherein the first switching sequence comprises switching the lighting units on or off, separately;

wherein the second switching sequence comprises switching the lighting units on or off, together;

wherein the lighting units comprise a first lighting unit and a second lighting unit, and

wherein the second lighting unit is turned off by the first switching sequence when the first lighting unit is turned on.

3. A lighting device comprising:

a contents receiving unit receiving contents through communication with an outside source;

a content analyzing unit detecting an output state of the contents by analyzing the contents received through the contents receiving unit;

a plurality of lighting units; and

a controller driving the lighting units based on the detected output state of the contents;

wherein the detected output state of the contents used to drive the lighting units includes information of a position of an object included in an image of the contents, and driving the lighting units includes switching one or more of the lighting units on or off based on the detected output state of the contents;

wherein, if the object included in the image is stationary, the controller allows the lighting unit of the plurality of lighting units corresponding to the position of the object to remain switched on while all lighting units of the plurality of lighting units that do not correspond to a position of an object in the image are switched off; and

wherein, if the object included in the image is moved, the controller switches on a lighting unit of the plurality of lighting units corresponding to a present position of the object, and switches off, by gradually reducing brightness thereof, a lighting unit of the plurality of lighting units corresponding to a previous position of the object.
