Lithium battery intelligent LED solar street lamp

Abstract

The invention discloses a lithium battery intelligent LED solar street lamp, and belongs to the technical field of street lamps. In the lithium battery intelligent LED solar street lamp, a cooling fan in an LED lamp cap can convey working heat into a lamp rod, so that the timely cooling of the lamp cap is guaranteed, and the service life of the street lamp is prolonged; a cooling pipe B connects a cooling fan with an accumulator accommodating cavity; when the environmental temperature of an accumulator is too low, the cooling pipe B conveys heat generated in LED working into the accumulator accommodating cavity to increase the use environmental temperature of the accumulator, so that the cooling performance of the lamp cap can be guaranteed, the discharge efficiency of the accumulator can be guaranteed, and the heat energy is reasonably used; an electric heating device is arranged in the accommodating cavity; when the heat dissipated in LED working cannot guarantee the use environmental temperature of the accumulator, the electric heating device is used for further heating; and the lithium battery intelligent LED solar street lamp is long in service life of a lithium battery, is high in charge / discharge efficiency, can fully use solar energy, and saves the energy.

Description

technical field [0001] The invention relates to the technical field of street lamps, in particular to a lithium battery intelligent LED solar street lamp. Background technique [0002] Lithium batteries have the advantages of high voltage, large capacity, small size, light weight, and wide operating temperature range. Lithium-ion battery packs have been widely used in various fields, including solar street lights and other fields. Lithium-ion batteries are more sensitive to the temperature of the operating environment. When the temperature is low, the dischargeable energy, power and discharge efficiency of the battery are low, and there are certain safety hazards when charging at low temperatures, such as the generation of dendrites. Therefore, the problem of low temperature use has greatly affected the application and promotion of lithium-ion batteries. At present, when the lithium battery installed on the solar street light is used in a low temperature environment, the di...

AI Technical Summary

Problems solved by technology

Lithium-ion batteries are more sensitive to the temperature of the operating environment. When the temperature is low, the dischargeable energy, power and discharge efficiency of the battery are low, and there are certain safety hazards when charging at low temperatures, such as the generation of dendrites, etc.

Therefore, the problem of low temperature use has greatly affected the application and promotion of lithium-ion batteries

At present, when the lithium battery installed on the solar street light is used in a low temperature environment, the discharge efficiency of the battery pack is relatively low, which seriously affects the power, service life and safety of the battery pack.

Not only that, the heat dissipation problem of the LED lamp holder is also a major problem of the existing LED solar street lights. The heat dissipation is not timely, which affects the service life of the LED street lights
