Because the heat source tray 1 is provided with the heat source through hole 26 communicated with the heat source cavity 19, air outside the passive thermoelectric camping lamp 100 can enter the heat source cavity 19 from the heat source through hole 26, so that the solid heat source 3 can be continuously combusted, and at the moment, the high-temperature-resistant heat-insulating cylinder 21 and the outer packaging layer 20 are not provided with through holes (not shown) communicated with the heat source cavity 19 and the outside of the passive thermoelectric camping lamp 100, so that the influence of the external environment on the passive thermoelectric camping lamp 100 is reduced; meanwhile, the waste gas generated by the combustion of the solid heat source 3 can also flow out of the heat source cavity 19 through the heat source through hole 26. Of course, the high temperature resistant heat insulation cylinder 21 and the outer packaging layer 20 may also be provided with through holes for communicating the heat source cavity 19 with the outside of the passive thermoelectric camping lamp 100, so as to make the combustion of the solid heat source 3 more sufficient.
Because the heat source tray 1 is provided with the heat source through hole 26 communicated with the heat source cavity 19, the coil spring 22 can be used for pushing the solid heat source 3 on the heat source tray 1 towards the uniform heat conducting pad 18, and at the moment, air outside the passive thermoelectric camping lamp 100 can enter the heat source cavity 19 from the heat source through hole 26 more easily. Meanwhile, the coil spring 22 may be used to push the solid heat source 3 on the heat source tray 1 toward the uniform heat conducting pad 18, so that the distance between the solid heat source 3 and the uniform heat conducting pad 18 is closer, and the temperature of the uniform heat conducting pad 18 rises faster when the solid heat source 3 burns.
As can be seen from fig. 7, in the passive thermoelectric camping lantern 100 according to an embodiment of the present invention, the greater the temperature difference between the temperature of the side of the thermoelectric device 17 near the uniform thermal pad 18 and the temperature of the side of the thermoelectric device 17 near the heat sink 16, the greater the voltage across the L ED assembly 13 (or the voltage generated by the thermoelectric device 17), and the greater the current flowing through the L ED assembly 13.
As can be seen from fig. 8, in the passive thermoelectric camping lamp 100 according to the embodiment of the invention, the voltage across the L ED module 13 and the power of the L ED module 13 increase as the current flowing through the L ED module 13 increases.
The passive thermoelectric camping lamp 100 provided by the invention effectively breaks through the technical bottleneck of the traditional camping lamp by taking the thermoelectric device 17 as the energy conversion component, simultaneously improves the electrical output performance of the camping lamp, has the characteristics of cleanness, environmental protection, long service life, strong applicability, large energy density and easy implementation, can work in the fields of home life, camp towering, frontier defense duty, field navigation, geological exploration, polar exploration and the like for a long time, and further meets the requirements of outdoor lighting equipment on greenness, cleanness and universality. Compared with the prior art, the invention adopts the thermoelectric effect as the main power generation mechanism, breaks through the technical bottlenecks of the traditional camping lamp, such as the limitation of the power density generated under the photoelectric effect or lithium battery technology power generation mode, the external environmental restriction and the like, and has reference value for the research of the new generation camping lamp.
