Illumination apparatus and method for controlling the same

An illumination apparatus that emits light from a light source using accumulated electric energy and that performs communication with another illumination apparatus via a communication unit, the illumination apparatus comprising:

• a capacitor configured to accumulate the electric energy used to emit light from the light source;
• a detection unit configured to detect a charge state of the capacitor;
• and
• a notification unit configured to perform notification indicating information on a determination whether the illumination apparatus is in a charge state in which light emission is available and notification indicating information on a determination whether the other illumination apparatus is in a charge state in which light emission is available in accordance with information on the other illumination apparatus received by the communication unit and a result of the detection performed by the detection unit.

A method for controlling an illumination apparatus that emits light from a light source using accumulated electric energy and that performs wireless communication with another illumination apparatus via a communication unit, the control method comprising:

• detecting a charge state of a capacitor that accumulates the electric energy used to emit light from the light source;
• receiving information on the other illumination apparatus via the communication unit;
• and
• performing notification indicating information on a determination whether the illumination apparatus is in a charge state in which light emission is available and notification indicating information on a determination whether both the illumination apparatus and the other illumination apparatus are in a charge state in which light emission is available in accordance with the received information on the other illumination apparatus and a result of the detection.
