The invention relates to an LED (Light Emitting Diode) street lamp with functions of radiating heat through superconductive liquid and replacing a driving power supply conveniently. The LED street lamp provided by the invention comprises multiple LED modules, a driving power supply for driving the LED modules and a heat radiating lamp body installed at the top of a lamp post, wherein the heat radiating lamp body comprises a heat radiating sheet, a lamp cavity for containing the LED modules and a photic cover plate. The LED street lamp provided by the invention is characterized in that the driving power supply is arranged at the bottom of the lamp post, i.e. a socket for inserting the driving power supply is arranged at the bottom of the lamp post; a superconductive liquid header pipe is also arranged on the heat radiating lamp body and communicated with a row of heat radiating branch pipes which are filled with the superconductive liquid and are arranged on the back surface of the heat radiating lamp body; the heat radiating sheet is in a hollow structure filled with the superconductive liquid; and the heat radiating sheet is communicated with the superconductive liquid header pipe. The invention overcomes the defects of the existing LED street lamp, so that the LED street lamp provided by the invention has the characteristics of high light emitting efficiency, good heat radiating effect, low power consumption, long service life, environment friendliness and the like, and a power supply is convenient to replace.
Description
1. Technical field [0001] The invention relates to an LED street lamp, in particular to an LED street lamp in which a superconducting liquid dissipates heat and is convenient for replacing a driving power supply. 2. Background technology [0002] With the development of LED, LED light source has the advantages of using low-voltage power supply, less energy consumption, strong applicability, high stability, short response time, no pollution to the environment, and multi-color light emission. Therefore, the wide application of LED has become a development trend. [0003] At present, the heat dissipation methods of LED street lamps mainly include natural convection heat dissipation, forced heat dissipation with fans, heat pipes and loop heat pipes, etc. The forced heat dissipation with fans is complex and has low reliability; the cost of heat pipes and loop heat pipes is high, and their The heat dissipation effect is not good, which greatly reduces the service life of the LED ...
