Abstract

The invention discloses a high-power LED module frame-type street lamp based on the heat dissipation of heat pipes, which comprises a high-power LED heat pipe thermal module, a framework device and a street lamp outer housing. The high-power LED heat pipe heat dissipation module is arranged on a framework device. In the high-power LED heat pipe heat dissipation module, at least one group of LED modules are arranged on an LED aluminium base; a plurality of LED modules are connected in series or in parallel; the heat sink of the LED is clung to and arranged on the LED aluminium base which is arranged on a heat pipe fixing plate, the two ends of which are provided with a T-shaped socket and the middle of which is provided with a slot way used for arranging the heat pipe. One end of the heat pipe is arranged on an arc slot way of the heat pipe fixing plate and the other end is provided with a heat dissipation fin. The frame-type street lamp realizes that the heat pipes are integrated on high-power LED heat dissipation devices, thus effectively solving the heat dissipation problem of the high-power LED in the street lamp application, and guaranteeing the working stability and service life of the high-power LED street lamp.

Description

technical field [0001] The invention relates to an LED street lamp, in particular to a high-power LED module frame-type street lamp based on a heat pipe for heat dissipation. Background technique [0002] Traditional road lighting mostly uses high-pressure sodium lamps, but LED street lamps have broad application prospects due to their advantages such as high luminous efficiency, low power consumption, no need for high voltage, and high safety. For example, a high-efficiency 60W LED street lamp can achieve the same lighting effect on the road as a 250W high-pressure sodium lamp, and its energy saving and high efficiency are very obvious. [0003] On the other hand, LED street lights require high brightness and high heat generation, and the outdoor use environment is relatively harsh. If the heat dissipation is not good, it will directly lead to rapid aging of LEDs and reduced stability. Therefore, efficient heat dissipation is one of the urgent problems to be solved in the ...
