Passive thermoelectric camping lights

Abstract

The invention discloses a passive thermoelectric camping lamp. The passive thermoelectric camping lamp comprises a heat source structure, a thermoelectric assembly and a light emitting component; theheat source structure comprises a high-temperature-resistant heat insulation cylinder, a heat source cavity penetrating through the high-temperature-resistant heat insulation cylinder is formed insidethe high-temperature-resistant heat insulation cylinder, and the heat source cavity is used for being provided with a solid-state heat source; the thermoelectric assembly comprises a high-temperature-resistant heat-insulating interlayer, a uniform heat conduction pad, a thermoelectric device and a radiator, the high-temperature-resistant heat-insulating interlayer is arranged on the high-temperature-resistant heat-insulating cylinder, the uniform heat conduction pad is arranged in the high-temperature-resistant heat insulation interlayer and shields one end of the heat source cavity, the thermoelectric device is arranged in the high-temperature-resistant heat-insulating interlayer and is fixed to one side, away from the high-temperature-resistant heat-insulating cylinder, of the uniform heat conduction pad, and the radiator is arranged on one side, away from the high-temperature-resistant heat insulation cylinder, of the thermoelectric device; and the light-emitting component is arranged on one side, away from the high-temperature-resistant heat insulation cylinder, of the high-temperature-resistant heat insulation interlayer and is electrically connected with the thermoelectric device, and the light-emitting component can emit light when being electrified. The passive thermoelectric camping lamp is large in energy density, long in service life, high in applicability, clean and environment-friendly.

Description

technical field [0001] The invention belongs to the application field of outdoor lighting and thermoelectric devices, in particular to a passive thermoelectric camping lamp. Background technique [0002] As a commonly used outdoor mobile lighting equipment, camping lights have important practical value in home life, camp setting up, frontier defense duty, field navigation, geological exploration, polar exploration and so on. At present, camping lamps with chemical energy or solar energy as the main energy conversion mode have been widely used, but they have great shortcomings. On the one hand, the energy conversion of chemical energy or solar energy has an obvious correlation with the size of the equipment, which makes the modularization and miniaturization of camping lights difficult. On the other hand, specifically, the external environment has severe restrictions on energy conversion methods such as chemical energy or solar energy, especially in harsh environments with m...
