A high power optical element streetlamp using a thermocouple includes a body unit, a lamp head unit, and a power supply unit fixed to the body unit. The lamp head unit includes a circuit board connected to the power supply unit, at least one optical element installed on the lower surface of the circuit board, a molding, and a heat dissipation plate installed on the upper end of the circuit board and including a plurality of heat dissipation fins to dissipate heat generated and transmitted from the at least one optical element and the circuit board. The thermocouple is arranged in the shape of a checkerboard on the surfaces of the heat dissipation fins and converts dissipated heat into thermoelectromotive force, and forming junctions where two kinds of metals having different thermal conductivities intersect to generate thermoelectric current is formed on the heat dissipation plate. |
