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 device receiving contents from an outside;

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 first and second switching sequences;

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;

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

wherein the lighting device is an indoor lighting device, and

wherein the lighting units are physically separated from the contents receiving device, a display unit for displaying of a video signal included in the contents and an audio output unit for outputting of the audio signal.

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

receiving by a contents receiving device, contents transmitted from an outside;

displaying by a display unit, a video signal included in the contents;

outputting by an audio output unit, an audio signal included in the contents,

detecting an audio signal included in the contents;

determining by a lighting device, 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;

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

controlling by the lighting device, a 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,

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

wherein the lighting device is an indoor lighting device, and

wherein the lighting units are physically separated from the contents receiving device, the display unit, and the audio output unit.
