Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawing and specific implementation
The present invention will be further described for example.It should be appreciated that described herein, specific examples are only used to explain the present invention, and does not have to
It is of the invention in limiting.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise
Under every other embodiment obtained, shall fall within the protection scope of the present invention.
As shown in Figure 1, the LED street lamp with radiator, which includes street lamp casing 10, radiator 20, preceding
End cap 50 and LED light source 60.The bottom surface of the radiator 20 is arranged in these LED light sources 60.The street lamp casing 10 includes multiple groups
Housing 110 is closed, is spaced apart from each other to form gap between these combination housings 110.These combination housings 110 are successively set on the heat dissipation
The top of device 20, so that (as shown in Figure 3) is arranged with respect to the top surface inclination of the radiator 20 in the gap.The drive end bearing bracket 50 setting exists
The front of the radiator 20.The two sides setting of the radiator 20 is provided with branch on the two side stands 30 there are two side stand 30
Frame mounting hole 31, after the housing mounting holes 11 that these rack mounting apertures 31 combine the setting of 110 two sides of the bottom of housing with these are aligned,
These combination housings 110 are fixed on the two side stands 30 by screw 40.
Fig. 1 and Fig. 3 is please referred to, each combination housing 110 is arch shell structure, the two sides of each combination housing 110
While being separately fixed at the two sides of the radiator 20.According to sequence from front to back, in addition to most preceding and last combination housing 100 it
Outside, the half that each combination housing 110 at 20 middle part of the radiator is arranged in is located under the latter combination housing 110 and separately
Half is located on previous combination housing 110.
Fig. 2 and Fig. 3 are please referred to, which is spliced by multiple radiating modules 21, is set on these radiating modules 21
Multiple cooling fins 211 are equipped with, these cooling fins 211 are made of a highly heat conductive material.Between these adjacent heat radiation modules 21 there are
Every 23.The LED street lamp 100 is provided with main shaft (not shown), these radiating modules 21 are each attached on the main shaft.These LED lights
Source 60 is lens and LED integrated optical source, and the back side of each 21 bottom plate of radiating module is arranged in.
When work, the heat that these LED light sources 60 sending at each 21 bottom plate back side of radiating module is arranged in passes through these
Radiating module 21 is transmitted to these combination housings 110, then is dispersed into outside from the gap for being spaced formation between these combination housings 110
In boundary's air.Since the half of each combination housing 110 is located at, the latter is combined under housing 110 and the other half is positioned at previous
On a combination housing 110, such structure, which can not only prevent dust, insect, birds droppings from falling on these cooling fins 211, to be influenced
Heat dissipation performance, and can make sunlight will not the direct irradiation radiator 20, help 20 effective temperature-reducing of radiator.
Since these radiating modules 21 are fixed on the main shaft 22, and spaced 23 between adjacent heat radiation module 21,
Therefore rainwater can combine these and radiate on housings 110 with these after washing away these and combining housings 110 under the stream of the interval 23
The dust accumulated on piece 211 washes away.On the one hand these gaps being obliquely installed can be such that more wind convection current pass through, another aspect energy
It prevents flying bird from piercing, destroys the LED street lamp 100.
In conclusion the LED street lamp 100 by the top of the radiator 20 be arranged combined type housing 110, can not only
Preventing dust, insect, birds droppings from falling on these cooling fins 211 influences heat dissipation performance, and the multiple-layer stacked of combined type housing 110
Structure can effectively keep the sun off, and can help 20 effective temperature-reducing of radiator.The combined type housing 110 of multilayer is capable of increasing street lamp
Effective heat dissipation area of shell 10, and the gap formed among these combined type housings 110 forms heated air and natural wind
The channel of convection current improves the effect of cross-ventilation heat dissipation.In addition, these combined type housings 110 can be naturally clear by rainwater
It washes, rainwater makes these combinations in the case where that can flow from the interval 23 between these radiating modules 21 after washing away these combination housings 110
Foreign matter on housing 110 and these cooling fins 211 will not be accumulated for a long time, and heat dissipation performance is kept to stablize.
Embodiments of the present invention above described embodiment only expresses, the description thereof is more specific and detailed, but can not
Therefore limitations on the scope of the patent of the present invention are interpreted as.It should be pointed out that for those of ordinary skill in the art,
Without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to protection model of the invention
It encloses.Therefore, the scope of protection of the patent of the invention shall be subject to the appended claims.
