A kind of high-power LED street lamp based on the heat radiation of heat pipe quick conductive

Technical field

The utility model relates to lighting apparatus, specifically is a kind of high-power LED street lamp based on the heat radiation of heat pipe quick conductive, is applicable in the LED road lamp system more than 100 watts.

Background technology

Great power LED is widely used in street lighting at present, because the operating ambient temperature of the performance of LED and life-span and the LED relation of being inversely proportional to has limited the application of LED.According to research, when the substrate temperature of LED was no more than 65 ℃, the encapsulating material of LED just can quick aging, has delayed the light decay of LED greatly, has increased the service life of LED, and can reach more than 30,000 hours service life.Because the LED shell is subjected to the restriction of encapsulating material, a large amount of heat energy accumulates on the chip substrate, and the heat that produces in the time of the LED luminous tube must work is dispersed in the air effectively, could guarantee that work exists under the temperature of LED worker's safety.And traditional radiating mode is used and the drawback of LED also is conspicuous, need a large amount of aluminiums exactly, the serious waste resource, simultaneously because the increase of area of dissipation causes the increase of material weight, heat dissipation technology has become the bottleneck of restriction LED street lamp industry development.Especially when LED street lamp application during to the road lighting of major trunk roads, the LED street lamp power nearly all will be more than hectowatt, the volume and weight that heat sink material is huge has become serious potential safety hazard.

Summary of the invention

At the deficiencies in the prior art, the utility model provides a kind of high-power LED street lamp based on the heat radiation of heat pipe quick conductive, and it can conduct the heat that LED produces apace and be dispersed in the air and go, and has improved LED street lamp effect in actual applications.

To achieve these goals, the utility model is realized with following technical scheme: a kind of high-power LED street lamp based on the heat radiation of heat pipe quick conductive comprises the street lamp shell that is used to dispel the heat and is installed in the interior LED heat pipe quick conductive module of street lamp shell; Described LED heat pipe quick conductive module has a metal heat-conducting substrate, in the upper surface of metal heat-conducting substrate heat pipe is installed, and the position in the lower surface of metal heat-conducting substrate corresponding to heat pipe is equipped with led light source.

The specific embodiment

As shown in Figure 1, a kind of high-power LED street lamp based on the heat radiation of heat pipe quick conductive comprises street lamp shell 1 that is used to dispel the heat and the LED heat pipe quick conductive module that is installed in the street lamp shell 1.Described LED heat pipe quick conductive module has a metal heat-conducting substrate 2, in the upper surface of metal heat-conducting substrate 2 heat pipe 3 is installed, and the position in the lower surface of metal heat-conducting substrate 2 corresponding to heat pipe 3 is equipped with led light source 4.

As shown in Figure 2, LED heat pipe quick conductive module is made up of heat pipe 3, metal heat-conducting substrate 2 and led light source 4.Its assembling mode is as follows: at first led light source 4 is installed on the lower surface of metal heat-conducting substrate 2, scribbles heat-conducting silicone grease between the substrate of led light source 4 and metal heat-conducting substrate 2, to strengthen heat-conducting effect and performance.Corresponding to the position that led light source 4 is arranged heat pipe 3 is installed in the upper surface of metal heat-conducting substrate 2 then.Led light source 4 can be that many of single above great power LED of 1W are used in combination, it also can be the great power LED of single power integrated encapsulation more than 30W, can be a this led light source 4 on the LED heat pipe quick conductive module, also can be many, do not limit at most, its arrangement mode can be single many, also can be that many rows are arranged side by side, can determine according to actual needs.Heat pipe 3 adopts the vacuum heat-pipe of copper or aluminum, and 3 at least one of the heat pipes at single LEDs light source back side also can be many.This heat pipe 3 is processed into the shape of " Z " font or " 7 " font, and the angle of its bending part is more than or equal to 90 degree.Compacting or on metal heat-conducting substrate 2 by machine cut/be processed with groove, one end of heat pipe 3 inserts or is pressed in the groove on the metal heat-conducting substrate 2, and,, improve heat-conducting effect with the increased thermal conductivity energy at the contact position of itself and its plate 2 of metal heat-conducting coating heat-conducting silicone grease.Heat pipe 3 compresses itself and its plate 2 of metal heat-conducting with metalwork after inserting or be pressed into groove on the metal heat-conducting substrate 2, tightens with screw then or the riveting jail.

With assembling finish on the LED heat pipe for thermal conductivity module other end of heat pipe 3 insert or be pressed into street lamp shell 1 top on groove or the hole in, with metalwork it is contacted tightly with the street lamp metal shell, tighten with screw then or the riveting jail, form a complete heat conduction and heat radiation system.A large amount of heat energy that the LED substrate produces pass to street lamp shell 1 by fast 3 speed of the heat pipe on the heat-conducting substrate 2, and by street lamp shell 1 heat that accumulates in the light fixture are delivered in the air fast and effectively.Street lamp shell 1 adopts aluminium shell.

Working method is: the mode that this LED street lamp adopts LED heat pipe for thermal conductivity module and the heat radiation of street lamp shell to combine, the heat that makes LED produce is conducted fast by this module gives the street lamp shell, and heat directly is dispersed in the air.Wherein the operation principle of LED heat pipe for thermal conductivity module is such: high-power LED light source 4 is installed on the metal heat-conducting substrate 2, between the substrate of led light source 4 and heat-conducting substrate 2, scribble heat-conducting silicone grease, to strengthen heat-conducting effect and performance, and the position corresponding to led light source 4 is equipped with heat pipe 3 on heat-conducting substrate 2, the other end of heat pipe 3 and street lamp shell 1 top are fixed together, form a complete heat conduction and heat radiation system, a large amount of heat energy that led light source 4 substrates are produced pass to street lamp shell 1 fast by the heat pipe on the metal heat-conducting substrate 23, and by street lamp shell 1 heat that accumulates in the light fixture are dispersed in the air.

Implementation result: the mode that the utility model has adopted LED heat pipe for thermal conductivity module and street lamp shell that heat conduction and heat radiation are implemented step by step, improved LED street lamp effect in actual applications, according to actual measurement, under the situation of same power, the weight of street lamp shell radiator has reduced two minutes one, and in the test of present embodiment, LED substrate center temperature only is 58 ℃, greatly prolonged the service life of LED, can be widely used in the LED road lamp system more than 100 watts.
