Abstract
The present invention relates to a candle-powered lighting apparatus including: a housing which accommodates a candle; a heat absorbing plate which absorbs heat generated by the candle; a heat radiating plate which radiates the absorbed heat; a thermoelectric element which is positioned between the heat absorbing plate and the heat radiating plate, and generates thermoelectromotive force using a temperature difference between a contact surface with the heat absorbing plate and a contact surface with the heat radiating plate; a lighting unit which emits light using the generated thermoelectromotive force; and a control unit which controls an operational state of the lighting unit to an on or off state.

A candle-powered lighting apparatus comprising:
- a housing which accommodates a candle;
- a heat absorbing plate which absorbs heat generated by the candle;
- a heat radiating plate which radiates the absorbed heat;
- a thermoelectric element which is positioned between the heat absorbing plate and the heat radiating plate, and generates thermoelectromotive force using a temperature difference between a contact surface with the heat absorbing plate and a contact surface with the heat radiating plate;
- a lighting unit which emits light using the generated thermoelectromotive force;
- a control unit which controls an operational state of the lighting unit to an on or off state;
- and
- an illuminance sensor which is positioned in the housing and measures luminous intensity of light emitted from a flame of the candle.
