  • Lighting device using combined power generation
    Patent number: 11879623
    Abstract: Proposed is a lighting device using combined power generation. Particularly, the lighting device using combined power generation includes a first power generation part including a first thermoelectric element whose first surface has a high temperature part formed by solar heat, the first power generation part being configured to generate electrical energy by using the first thermoelectric element, a second power generation part including a second thermoelectric element whose first surface has a high temperature part formed by heat generated from an LED module, the second power generation part being configured to generate electrical energy by using the second thermoelectric element, and a cooling part that is provided between the first power generation part and the second power generation part and simultaneously cools a second surface of each of the first thermoelectric element and the second thermoelectric element.
    Type: Grant
