Wind, light and thermoelectricity complementary light-emitting diode (LED) streetlamp device

Abstract

The invention provides a wind, light and thermoelectricity complementary light-emitting diode (LED) streetlamp device, which comprises a solar panel, a wind power generator, an LED light source, a thermoelectric converter, a radiator, a lampshade, a wind, light and thermoelectricity control system and a storage battery. The thermoelectric converter is arranged at the back of the LED light source. The hot end of the thermoelectric converter is connected with a metallic heat absorbing sheet which is in direct contact with the back of the LED light source. The cold end of the thermoelectric converter is connected with a metallic heat dissipating sheet of the radiator. The radiator additionally comprises radiating fins with different lengths. The lampshade is divided into an upper part and a lower part. The upper part is a radiating lampshade body and is connected with the radiating fins. The lower part is a transmission lampshade body to transmit the light source of an LED lamp. The output end of the thermoelectric converter is respectively connected with the storage battery and a constant-current source through a control circuit of the wind, light and thermoelectricity control system. The constant-current source provides constant current to the LED light source. The storage battery supplies power to the LED light source when the power is needed. The wind, light and thermoelectricity complementary LED streetlamp device has the advantages of simple structure and low cost, and is suitable for roads in remote mountainous areas and expressways.

Description

technical field [0001] The present invention relates to a street lamp device, in particular, the present invention relates to a wind-solar-heat-electric complementary LED street lamp device for highways or remote mountainous roads. Background technique [0002] In recent years, my country's urban road network and expressways have developed rapidly. Conventional street lights must be powered by buried cables. If the lighting line is extended, a booster system is also required. Therefore, most suburban roads and expressways far away from power points are not installed. street light. The emergence of wind-solar hybrid street lamps avoids the disadvantages of long-distance power supply to street lamps. Solar and wind energy are highly complementary in time distribution. During the day, when the sun is strongest, the wind is generally low. At night, there is no sun, only weak moonlight, but the wind is generally strong; in summer, the wind is generally low and the sun is strong,...

AI Technical Summary

Problems solved by technology

[0010] The present invention aims at the disadvantages of poor heat dissipation effect, short lighting time, inability to combine with wind-solar hybrid system and low heat recovery utilization rate in the prior art, and provides a wind-solar thermal-electric complementary LED street lamp device, which can not only realize high-efficiency heat dissipation, but also It can make full use of part of the waste heat and convert it into electric energy, and can work together with solar and wind power to greatly extend the lighting time of street lights at night
