Description

A kind of high-power LED street lamp

Technical field

The utility model relates to the LED lighting engineering, more particularly relates to a kind of high-power LED street lamp.

Background technology

At present, energy problem has become the key issue that affects various countries' development, and is therefore energy-saving and cost-reducing imperative.The LED street lamp has the trend that replaces the conventional high-tension sodium vapor lamp with the characteristics of its high efficiency, low energy consumption and long-life etc., and prospect is extremely extensive.But the LED street lamp also has fatal defective, because the luminous electric light source that is similar to of LED, the heat of generation is difficult to shed, and causes concentrating of heat.If cooling measure is bad, temperature can sharply raise, and when spending above 60, can aggravate light decay, lowers efficiency, and the life-span seriously shortens simultaneously, so the heat dissipation problem of LED street lamp becomes the key factor that affects its performance.More existing structures are to adopt to install the fan forced heat radiation additional, or use heat pipe or loop circuit heat pipe etc., but the problem that these structures exist is the design complexity, and cost is higher, and perhaps reliability is not high.Also having some is the structures that adopt fin to conduct heat, but the shortcoming of its existence is only to emphasize the heat conduction, has ignored free convection, still causes the not high problem of radiating efficiency.And traditional radiator is basically take aluminum as main, and the difficulty of processing of metal material own is large, and quality is heavy.

The utility model content

For the defective that exists in the prior art, the purpose of this utility model provides a kind of simple in structure, not only considers the heat conduction, also considers the high-power LED street lamp of Natural Convection Problem, and its thermal diffusivity is good.

For achieving the above object, the utility model adopts following technical scheme:

A kind of high-power LED street lamp, comprise lamp main body, U-shaped pedestal, radiating fin, led light source module, control element and lampshade, be provided with vertically at least one U-shaped pedestal in the described lamp main body, the both sides of described U-shaped pedestal are provided with and are the radiating fin that pectination is arranged, and described radiating fin links to each other with lamp main body and U-shaped pedestal respectively; Be provided with control element and led light source module in the described U-shaped pedestal, described control element links to each other with the led light source module, and the opening part of described U-shaped pedestal is provided with lampshade.

The cross section of described high-power LED street lamp is inverted trapezoidal structure.

Described radiating fin and described lamp main body adopt integrative-structure.

Described lamp main body, U-shaped pedestal and radiating fin all adopt the heat-conducting type plastic material.

Compared with prior art, adopt a kind of high-power LED street lamp of the present utility model, comprise lamp main body, U-shaped pedestal, radiating fin, led light source module, control element and lampshade, be provided with vertically at least one U-shaped pedestal in the described lamp main body, the both sides of described U-shaped pedestal are provided with and are the radiating fin that pectination is arranged, and described radiating fin links to each other with lamp main body and U-shaped pedestal respectively; Be provided with control element and led light source module in the described U-shaped pedestal, described control element links to each other with the led light source module, and the opening part of described U-shaped pedestal is provided with lampshade.Because radiating fin is the both sides that pectination is arranged in the U-shaped pedestal, form heat-dissipating space between the adjacent like this radiating fin, and run through whole lamp main body, such structure not only can play heat conducting effect, but also increased the free convection of air, greatly improved radiating efficiency, so that prolong the service life of LED street lamp.

Description of drawings

Fig. 1 is the structural representation of a kind of high-power LED street lamp of the present utility model;

Fig. 2 is the cutaway view of the high-power LED street lamp among Fig. 1;

Fig. 3 is the structural representation of left back cover among Fig. 2, right back lid and middle bonnet.

The specific embodiment

Further specify the technical solution of the utility model below in conjunction with drawings and Examples.

See also Fig. 1, Fig. 2, a kind of high-power LED street lamp shown in Figure 3 comprises lamp main body 11, be provided with vertically 3 U-shaped pedestals 121 that are parallel to each other in the lamp main body 11,122,123, one of them U-shaped pedestal 121 is located on the axis of lamp main body 11, two U-shaped pedestals 122 in addition, 123 are located at respectively the both sides of lamp main body 11, at U-shaped pedestal 121, between 122, U-shaped pedestal 121, between 123 and U-shaped pedestal 122,123 the outside is equipped with and is the radiating fin 13 that pectination is arranged, radiating fin 13 respectively with lamp main body 11 and U-shaped pedestal 121,122,123 link to each other, and radiating fin 13 is structure as a whole with lamp main body 11, form heat-dissipating space between the adjacent like this radiating fin, run through whole lamp main body.Be provided with control element 16 and led light source module 14 in the U-shaped pedestal 121,122,123, control element 16 links to each other with led light source module 14, and the opening part of U-shaped pedestal 12 is provided with lampshade 15.Lampshade 15 is fixed on the U-shaped pedestal at U-shaped pedestal 121,122,123 inboard set mounting grooves by plug-in card.The cross section of described high-power LED street lamp is inverted trapezoidal structure, because lampshade 15 is that curved surface is circular-arc, it is circular-arc that the shape of arranging that is arranged on the radiating fin 13 of lamp main body 11 zone lines also is curved surface, when rainy day, rainwater can carry out good washing to the radiator structure of lamp main body 11 and radiating fin 13 compositions like this.Be provided with the hermetically-sealed construction that is comprised of left back cover 17, right back lid 19 and middle bonnet 18 in the outside of lamp main body 11, left back cover 17, right back lid 19 and middle bonnet 18 are screwed on lamp main body 11.

Therefore lamp main body of the present utility model, U-shaped pedestal and radiating fin all adopt the heat-conducting type plastic material, have the advantages such as the simple and quality of processing is slim and graceful.

Those of ordinary skill in the art will be appreciated that, above embodiment illustrates the purpose of this utility model, and be not with opposing restriction of the present utility model, as long as in essential scope of the present utility model, all will drop in the scope of claim of the present utility model variation, the modification of the above embodiment.
