Heat dissipation mechanism of LED street lamp

Abstract

A heat dissipation mechanism of an LED street lamp comprises a lamp holder, heat dissipation assemblies, a transmission assembly and an energy supply assembly; the lamp holder is arranged on a streetlamp post; a plurality of groups of lamp beads are arranged, lamp tubes are arranged on the lamp beads, and the lamp beads are arranged on the lamp holder; the heat dissipation assembly is arranged onthe plurality of groups of lamp tubes; the transmission assembly driven by the energy supply assembly is connected with the plurality of groups of heat dissipation assemblies; the energy supply assembly is arranged on the lamp holder and is a wind power generation assembly. According to the invention, the heat dissipation assemblies are arranged, heat dissipation sleeves are used for dissipatingheat of the lamp tubes, heat on the lamp tubes is dissipated in a small space, and heat dissipation holes are formed, so that the heat dissipation efficiency is improved; a thermocouple is used for monitoring the temperature near the lamp beads and the lamp tubes, so that better heat dissipation performance can be provided after analysis, research and judgment; by arranging the transmission assembly, the multiple sets of heat dissipation sleeves are driven to synchronously rotate on the lamp tubes, so that internal air circularly flows, and the heat dissipation efficiency is improved; by arranging the energy supply assembly, a third rotating shaft is driven by wind power to rotate, and therefore the transmission assembly is driven to rotate.

Description

technical field [0001] The invention relates to the technical field of heat dissipation for street lamps, in particular to a heat dissipation mechanism for LED street lamps. Background technique [0002] Light-emitting diodes are referred to as LEDs for short. Made of compounds containing gallium, arsenic, phosphorus, and nitrogen, among others. Visible light can be radiated when electrons and holes recombine, so they can be used to make light-emitting diodes. It is used as an indicator light in circuits and instruments, or as a text or number display. Gallium arsenide diodes emit red light, gallium phosphide diodes emit green light, silicon carbide diodes emit yellow light, and gallium nitride diodes emit blue light. Due to chemical properties, it is divided into organic light-emitting diode OLED and inorganic light-emitting diode LED.

AI Technical Summary

Problems solved by technology

[0003] Although the heat dissipation of LED lamp tubes is very small compared with incandescent lamps, heat will still be generated under long-term work, which will affect the normal operation of lamp beads and lamp tubes. The existing heat dissipation devices have poor energy-saving and environmental protection performance. And the structure is relatively complicated, which will cause too much burden on the LED lamps, and it is impossible to realize heat dissipation in a small amount of space
