Lighting device, lighting system including the same, and method of operating the same

摘要

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.

主权项

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.
