The small device design of convex lens concentrating light and hermocouple generating electricity

The article provides a small device design of convex lens concentrating light and hermocouple generating electricity. According to the principle of thermocouple measuring temperature, when a thermoelectrical generates potential, the device can convert the potential to electricity.Hot end uses convex for focus light to heat and cold end uses water cooling. In order to generate large potential,the thermocouple is in series with ohers.And adopt the scattering shape to arrange. Meanwhile, we use DC millivoltmeter to measure the electric potential. lt has the advantages of simple device space small, optical energy little wasting, saving investment, and low operation fare. What´s more,it´s good for keeping sustainable development as saving energy and environmental protection.
