Self-powered street lamp post

Abstract

The invention discloses a self-powered street lamp post. The street lamp post comprises a post body and a thermoelectric power generation device positioned at the upper part of the post body. The thermoelectric power generation device comprises a plurality of thermoelectric power generation components, a storage battery, an LED lamp, a self-induction light control switch and a conductive cable, wherein the storage battery is placed in a storage box, and the self-induction light control switch is arranged on an upper cover of the post body; the surface of the upper part of the post body is provided with a FeMnCuO4 solar light heat absorption coating, a high-thermal-conductivity silicone grease coating is arranged between the FeMnCuO4 solar light heat absorption coating and the hot end facesof the thermoelectric generation components, and a heat reflection coating is arranged on the cold end faces of the thermoelectric generation components. According to the street lamp post, through the light heat absorption coating, the high-thermal-conductivity silicone grease coating, the power generation components and the heat reflection coating which are stacked on the surface of the lamp post from inside to outside, the difference between the metal temperature of the surface of the street lamp post and the environment temperature can be increased to 30 DEG C or above, so that the temperature difference at the cold and hot ends of the thermoelectric power generation components is greatly increased, the generated thermoelectric power is thus increased, and a street lamp can be self-powered.

Description

technical field [0001] The invention belongs to the technical field of lighting facilities, and in particular relates to a self-powered street light pole. Background technique [0002] Energy is the lifeblood of economic development, and sufficient energy is the basis for ensuring the sustainable development of the national economy. However, although my country has a vast territory, its per capita resources are very small. With the continuous and rapid development of my country's economy and the progress of urbanization, the demand for energy is also rising. In recent years, with the rapid economic development, energy and environmental problems have become more and more serious. Finding safe and reliable new energy has become a problem that both the government and researchers are paying attention to. Therefore, many pollution-free new energy technology products have emerged as the times require. [0003] Thermoelectric power generation devices (also known as thermoelectri...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the technical problem that the temperature difference between the lighting pole of the existing temperature difference generating circuit lamp and the ambient temperature is small, resulting in low power generated by the temperature difference and unable to provide lighting for the street lamp, the purpose of the present invention is to provide a self-powered street lamp pole. The light and heat-absorbing coating, high thermal conductivity silicone coating, power generation components and heat-reflecting coating layered on the surface of the pole from the inside to the outside can increase the difference between the metal temperature on the surface of the street light pole and the ambient temperature to more than 30°C, Greatly increase the temperature difference between the hot and cold ends of thermoelectric power generation components, thereby increasing the power of thermoelectric power generation, so as to realize the self-supply of street lamps
