Abstract

The utility model discloses an LED streetlamp, which comprises an aluminum casing, an LED substrate arranged in the aluminum casing and two groups of radiating components. The radiating components mainly consist of radiating fins, both the two groups of radiating components are connected with the casing via heat pipes, wherein heat absorbing sections of the heat pipes are fixed on the back surface of the casing via press plates, radiating sections of the heat pipes penetrate through the radiating fins of the radiating components and are fixedly connected with the radiating fins, and a plurality of through holes are uniformly arranged on the radiating fins. The LED streetlamp adopts the heat pipes and the radiating components, can more quickly dissipate generated heat, and is favorable for prolonging the service life. The through holes are uniformly arranged on the radiating fins, so that contact surfaces among the radiating fins and air are larger, and the LED streetlamp is better in radiating effect and simple in structure, and is convenient and practical.

Description

A kind of LED street lamp

Technical field

The utility model relates to a kind of street lamp, relates in particular to a kind of LED street lamp.

Background technology

At present, street lamp has become the indispensable instrument of road lighting.And for energy savings more, people use the LED technology above the street lamp, but the caloric value of LED lamp is very big, if the heat that produces can not get distributing timely, will have a strong impact on the working life of street lamp, though people have adopted the method for a lot of raising radiating effects, the heat radiation of existing street lamp is still not ideal enough.

The utility model content

The purpose of this utility model just is to provide a kind of LED street lamp, can greatly improve the radiating effect of street lamp, the working life that prolongs street lamp.

To achieve these goals, the technical solution adopted in the utility model is such: a kind of LED street lamp, the LED substrate that comprises aluminum shell and Qi Nei, also comprise two groups of radiating subassemblies, described radiating subassembly mainly is made of fin, and two groups of radiating subassemblies all link to each other with shell by heat pipe, wherein, the endotherm section of heat pipe is fixed on the shell back side by pressing plate, and its radiating segment passes the fin of radiating subassembly and fixedlys connected with fin, also evenly has some through holes on fin.

As preferably, the corresponding groove that adapts with heat pipe heat-absorbing section that has on the described shell back side and the pressing plate.

As preferably, described heat pipe takes the shape of the letter U.

Compared with prior art, advantage of the present utility model is: adopt heat pipe to add radiating subassembly, the heat that can quickly the LED lamp be produced is taken away, help to prolong the service life of street lamp, evenly have some through holes on the described fin, make that the contact-making surface of fin and air is bigger, radiating effect is better, makes that the illuminating effect of street lamp is better; Correspondence has the groove that adapts with heat pipe heat-absorbing section on the described shell back side and the pressing plate, can be with the heat pipe compressive strain; Described heat pipe takes the shape of the letter U, and makes street lamp more attractive in appearance, and is simple in structure, convenient and practical.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a side view of the present utility model;

Fig. 3 is the structural representation of another angle of the utility model.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

Embodiment: referring to Fig. 1, Fig. 2 and Fig. 3, the utility model comprises the LED substrate 2 of aluminum shell 1 and Qi Nei, also comprise two groups of radiating subassemblies 4, described radiating subassembly 4 mainly is made of fin, and two groups of radiating subassemblies 4 all link to each other with shell 1 by heat pipe 5, and described heat pipe 5 takes the shape of the letter U, wherein, the endotherm section of heat pipe 5 is fixed on shell 1 back side by pressing plate 3, the corresponding groove that adapts with heat pipe 5 endotherm sections that has on described shell 1 back side and the pressing plate 3, the radiating segment of this heat pipe 5 passes the fin of radiating subassembly 4 and fixedlys connected with fin, also evenly has some through holes 6 on fin.

The utility model adopts heat pipe 5 to add radiating subassembly 4, the heat that can quickly the LED lamp be produced is taken away, help to prolong the service life of street lamp, evenly have some through holes 6 on the described fin, make that the contact-making surface of fin and air is bigger, radiating effect is better, make that the illuminating effect of street lamp is better, the corresponding groove that adapts with heat pipe 5 endotherm sections that has on described shell 1 back side and the pressing plate 3, can be with heat pipe 5 compressive strains, described heat pipe 5 takes the shape of the letter U, and makes street lamp more attractive in appearance, simple in structure, convenient and practical.

Can also add an outer cover in shell of the present utility model 1 back during use, to prevent that mosquito, dust etc. from influencing radiating effect, when the powerful illumination of needs, the disclosed LED street lamp of a plurality of the utility model can also be combined, and utilize a big outer cover that it is covered, use flexible more, convenient.

Claims
