CN103759215A, the day for announcing is on April 30th, 2014, and this application case discloses a kind of road lamp system of utilization thermo-electric generation,
Including light fixture, lamp stand and semiconductor temperature differential generating block, a pole of semiconductor temperature differential generating block is connected to underground, and another pole connects
The air on ground is connected to, the electric energy output of semiconductor temperature differential generating block connects light fixture by inversion and control device, and this is
The semiconductor temperature differential generating block of system using underground and ground air thermo-electric generation, no matter cold and extremely hot, also no matter daytime and
Evening, this temperature difference exists always, thus it is this generating also just carry out always, in the system, metal shell good thermal conduction, pass
Deep fat good and specific heat capacity of conducting heat is big, can sense temperature exactly, can keeps thermally-stabilised well, reach the effect of power generation stabilization
Really.But LED projector lamp is generally fixed on ground or set aloft, it has not been convenient to which the cold end of thermoelectric generator is arranged on
Underground, and this is far, it is necessary to which sufficiently long partly lead using distance between the road lamp system hot junction of thermo-electric generation and cold end
Volume elements part, processing difficulties, cost are too high.
