Heat pipe radiator and high-power LED road lamp

Abstract

The invention relates to a lighting device, especially relating to a sinking device and a high-power LED road lamp. A heat pipe sinking device comprises a heat transfer plate, a heat pipe and a fin. The heat transfer plate comprises an amount of aluminium base plate fixation plates, at least two central fixation plates and a heat pipe pressure plate, all of which are stacked together and connected fixedly. The central fixation plate is disposed between the aluminium base plate fixation plate and the heat pipe pressure plate. One end of the heat pipe is disposed in a groove formed by two adjacent central fixation plates, and the other end thereof is disposed in a groove on the bottom of the fin. The high-power LED road lamp comprises the heat pipe sinking device, a casing, a high-power LED luminous tube and an electric power source control circuit. A LED light source provided with the high-power LED luminous pipe is fixed on the aluminium base plate fixation plate. The invention provides a heat pipe sinking device with high heat sinking efficiency, and also provides a high-power LED road lamp having the heat pipe sinking device at the same time.

Description

(1) Technical field: [0001] The invention relates to a lighting appliance, in particular to a heat dissipation device and a high-power LED street lamp. (two), background technology: [0002] Traditional road lighting often uses high-pressure sodium lamps, which have two fatal shortcomings of high energy consumption and short life. With the maturity of LED manufacturing technology, LED street lighting has emerged as the times require, which overcomes the shortcomings of high-pressure sodium lamps. Notable features of low power consumption and long life. Most of the high-power LED street lamps in the prior art have heat dissipation problems, and the quality of heat dissipation directly affects the working life and reliability of high-power LED street lamps. The heat generated by the power LED street lamp is directly transmitted to the heat sink, and then radiated out. The main disadvantage of this heat dissipation method is that the heat dissipation area of ​​the heat sink is...

Problems solved by technology

[0002]Traditional road lighting often uses high-pressure sodium lamps, which have two fatal shortcomings of high energy consumption and short life. With the increasing maturity of LED manufacturing technology, LED street lighting Then it came into being, which overcomes the shortcomings of high-pressure sodium lamps, and has the remarkable characteristics of low energy consumption and long life

Most of the high-power LED street lamps in the prior art have heat dissipation problems, and the quality of heat dissipation directly affects the working life and reliability of high-power LED street lamps. The heat generated by the power LED street lamp is directly transmitted to the heat sink, and then radiated out. The main disadvantage of this heat dissipation method is that the heat dissipation area of ​​the heat sink is not large enough, the heat dissipation efficiency is not high enough, and the convection between the heat sink and the air is not very good. good

Heat pipe heat dissipation technology is a heat dissipation method with high heat dissipation efficiency. For example, the patent document with the notification number CN 2068224U discloses a heat pipe radiator, and describes the high efficiency of heat pipe heat dissipation. No examples of applying heat pipe cooling technology to high-power LED street lamps have been found
