A portable lighting device with thermoelectric power generation which includes a thermoelectric power generation module ( 001 ), a mounting top panel ( 004 ), a light emitting unit ( 003 ) on the mounting top panel ( 004 ), an adjustment rod ( 002 ) connecting between the thermoelectric power generation module ( 001 ) and the mounting top panel ( 004 ). The thermoelectric power generation module ( 001 ), having a hot and a cold sides, includes a heat dissipation unit ( 100 ) proximal to the cold side, a thermoelectric power generation chip set ( 110 ), a heat supply box ( 120 ) proximal to the hot side and a combustion chamber ( 130 ) connected to the bottom of the heat supply box. The thermoelectric power generation module ( 001 ) power generation has a laminated composite structure formed by different thermoelectric power generation materials which work under different temperature ranges aligned sequentially in layers from the cold side to the hot side for thermoelectric power generation. |
