Energy-saving street lamp

Abstract

The invention belongs to the field of street lamps, and provides an energy-saving street lamp. The energy-saving street lamp comprises an LED lamp bead, a thermoelectric power generation sheet, a radiator, a switch voltage-stabilized power supply, an energy storage device and a cooling fan; the thermoelectric power generation sheet is arranged on a substrate of the LED lamp bead and is connected with the switch voltage-stabilized power supply; the switch voltage-stabilized power supply is connected with the cooling fan and the energy storage device; and the energy storage device is connected with the LED lamp bead. According to the energy-saving lamp, the normal heating value of the LED lamp can be reutilized, energy is saved, and energy consumption is reduced. The power generated by the thermoelectric power generation sheet can be used for supplying power to the LED cooling fan. After the energy is stored by the energy storage device, a mobile power supply of a passerby can be chargedthrough a USB interface, and / or the LED lamp is powered, and / or the cooling fan is powered. When the thermoelectric power generation is used for the cooling fan, the heat dissipation of the LED can be remarkably improved, and the service life of the LED lamp is prolonged.

Description

Technical field[0001]The present invention relates to a street lamp, in particular to an energy saving street lamp.Background technique[0002]my country's lighting consumption electricity accounts for 13 to 14% of China's power generation, with road lighting energy consumption accounts for 20 to 30% of total lighting energy consumption, which is known that road lighting is very high, how to reduce road lighting energy consumption is Problems with continued attention in this field. Typically, road LED lighting can utilize solar energy, wind energy as a supplement to municipal power supply, but in practical applications, such as Sichuan, Yunnan, Guizhou are affected by geographical environments, low light, and small density, etc. The utilization rate of solar and wind energy is low, and the production capacity is small, and it does not effectively reduce the consumption of road lighting. Further, in the lighting light of the LED streetlight, although the LED luminous efficiency is high...

AI Technical Summary

Problems solved by technology

Usually, road LED lighting can use solar energy and wind energy as a supplement to municipal power supply. However, in practical applications, Southwestern regions such as Sichuan, Yunnan, and Guizhou are affected by the geographical environment, with low sunlight intensity and low wind power density. The utilization rate of solar and wind energy is low, and the production capacity is low, which cannot effectively reduce the consumption of mains power for road lighting

Moreover, in high-power LED street lighting, although LED luminous efficiency is high, 70% to 85% of its input energy is converted into heat and wasted, and if the energy cannot be exported in time, it will also affect the life of LED street lamps.
