Abstract
A light emitting device includes: a light emitter for generating light; a communication unit that communicates externally through a first communication mode to receive time information and communicates externally through a second communication mode different from the first communication mode; and a controller for controlling a correlated color temperature of the light of the light emitter based on the time information. Further, the communication unit transmits the time information received using the first communication mode externally through the second communication mode.

A light emitting device comprising:
- a light emitter for generating light;
- a communication unit that communicates externally through a first communication mode to receive time information and communicates externally through a second communication mode different from the first communication mode;
- and
- a controller for controlling a correlated color temperature of the light of the light emitter based on the time information.
A light emitting device comprising:
- a light emitter for generating light;
- a communication unit that communicates externally through a first communication mode and communicates externally through a second communication mode different from the first communication mode to receive a driving signal;
- and
- a controller that drives the light emitter to emit light when the driving signal is received.
A light emitting system comprising:
- a light emitting device that generates light;
- and
- a transmission terminal that communicates with the light emitting device to transmit time information to the light emitting device,
- wherein the light emitting device includes:
- a light emitter for generating light;
- a communication unit that communicates with the transmission terminal using a first communication mode to receive the time information and communicates externally through a second communication mode different from the first communication mode;
- and
- a controller for controlling a correlated color temperature of the light of the light emitter based on the time information.
