Description
Technical field
The utility model relates to the relevant technical fields of street lamp, and in particular to be a kind of height of outdoor LED street lamp
Imitate radiator structure.
Background technology
The heat radiating fin structure of common LED street lamp is mostly using exposed design, such structure currently on the market
Although whole heat dissipation effect can be improved effectively, rainwater can be along radiating fin and shell in actual application process
Edge between body enters in lamp housing, serious to burn out internal circuit board, in order to solve this problem, current at present
Method be to increase by a circle cushion rubber in seam crossing to carry out waterproof, but will will lose and should have with the aging of cushion rubber once for a long time
Waterproof action, to reduce its whole service life.
Utility model content
The utility model aim is to provide a kind of high-efficiency heat radiation structure of outdoor LED street lamp, it can efficiently solve background
The problem of in the presence of technology.
In the presence of solving the problems, such as background technology, it includes lamp housing 1, and one is equipped at the upper top surface of the lamp housing 1
A circle locating ring 3 is axially outwardly extended in the bottom of a weather shield 2, the lamp housing 1, is provided between the locating ring 3 and lamp housing 1
One positions side 4, and mounting plate 5 is provided in the locating ring 3, and the edge of the mounting plate 5 is fixed on positioning side 4, institute
The middle part perforation for stating mounting plate 5 offers loophole 6, and the top of the mounting plate 5 is equipped with LED lamp panel 7, the LED lamp panel 7
In the surface of loophole 6, the bottom of the mounting plate 5 is equipped with lampshade 8, which is located at the underface of loophole 6, institute
The radiating fin 9 that several equidistant arrangements are installed at the back side of LED lamp panel 7 is stated, the periphery of the lamp housing 1 offers a circle
Heat emission hole 11.
It is arc dome structure at the upper top surface of the weather shield 2, outer diameter is slightly larger than the internal diameter of lamp housing 1.
The circumferential annular array of the mounting plate 5 has the ventilation hole 10 of several perforation settings.
As a result of above technical scheme, the utility model has the advantages that：It is simple in structure, heat dissipation effect reason
Think, while can also effectively completely cut off the infiltration of rainwater, improves whole service life.
Description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
It puts, other drawings may also be obtained based on these drawings.
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
In order to make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, under
Face will combine the attached drawing in the utility model embodiment, be carried out to the technical scheme in the embodiment of the utility model clear, complete
Ground describes.
Referring to Fig. 1, present embodiment is achieved using following technical scheme, it includes lamp housing 1, the lamp housing 1
Upper top surface at installation there are one weather shield 2, a circle locating ring 3, the locating ring are axially outwardly extended in the bottom of the lamp housing 1
Setting is provided with mounting plate 5, the edge of the mounting plate 5 there are one side 4 is positioned in the locating ring 3 between 3 and lamp housing 1
It is fixed on positioning side 4, the middle part perforation of the mounting plate 5 offers loophole 6, and the top of the mounting plate 5 is equipped with LED
Lamp plate 7, the LED lamp panel 7 are located at the surface of loophole 6, and the bottom of the mounting plate 5 is equipped with lampshade 8, which is located at
The underface of loophole 6 is installed with the radiating fin 9 of several equidistant arrangements, the lamp at the back side of the LED lamp panel 7
The periphery of shell 1 offers a circle heat emission hole 11.
It is arc dome structure at the upper top surface of the weather shield 2, outer diameter is slightly larger than the internal diameter of lamp housing 1.
The circumferential annular array of the mounting plate 5 has the ventilation hole 10 of several perforation settings.
The application method and its principle of technical solution part in present embodiment are made below in conjunction with the accompanying drawings further
Elaboration：
When rainy, rainwater can be gone out by 2 quick water conservancy diversion of weather shield, prevented rainwater heat radiating via hole 11 and entered
The phenomenon of the short circuit of LED lamp panel 5 is caused between locating ring 3 and lamp housing 1, and makes internal air by heat emission hole 11 and ventilation hole 10
Flowing up and down for smoothness is generated, the effect of integral heat sink is improved.
Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model, rather than its limitations；
Although the utility model is described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that,
It still can be with technical scheme described in the above embodiments is modified, or is carried out to which part technical characteristic etc.
With replacement；And these modifications or replacements, various embodiments of the utility model technology that it does not separate the essence of the corresponding technical solution
The spirit and scope of scheme.
