Description
Technical field
This utility model relates to a kind of LED street lamp light fixture, is specifically related to a kind of LED street lamp lamp with radiating structure
Tool.
Background technology
It is known that LED does not produce heat as cold light source itself, but drive LED will produce substantial amounts of heat, especially
The high-power LED chips such as such as LED street lamp are relatively big by electric current, when drive circuit components and parts are many in addition, can not keep away during its work
Exempt to produce bigger heat.
At present, LED lamp uses single finned radiator or radiating tube mode to dispel the heat mostly, but is as
Incrementally increasing of LED encapsulation power, the heat produced when being difficult to solve LED lamp work only by single radiating mode.Especially
It is when, after LED modularity, the IP grade of light fixture makes it increase sealing requirements, makes heat dissipation problem more highlight.
Utility model content
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model there are provided a kind of heat sinking formula
LED street lamp light fixture, finned radiator and radiating tube, by designing the optimization of structure, are integrated, in making LED lamp by it
LED module radiator and the heat of Switching Power Supply distributed to LED to greatest extent by lamp interior structure, thus
Reach the purpose of LED lamp heat radiation.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of heat sinking formula LED street lamp light fixture, includes lamp housing and radiating tube, is provided with LED module in described lamp housing
Heat abstractor and Switching Power Supply, lamp housing is external to upper end and is provided with radiating fin, and a part for described radiating tube is arranged at lamp housing
Internal to be attached on described LED module radiator and Switching Power Supply, radiating tube another part is disposed through described dissipating
Between hot fin, to transfer heat to each radiating fin.
Further, it is preferred that, described radiating tube is O type radiating tube.
Further, it is parallel to each other and spaced set between described each radiating fin.
Further, it is preferred that, the gap between described each radiating fin is 4mm～6mm.
By above technical scheme, this utility model compared with the existing technology, can not only use active cold and hot sky
Gas convection circulation is dispelled the heat, and radiating fin is combined radiating tube, it is achieved optimal radiating effect, its simple in construction, manufacture simultaneously
Low cost, the suitability are strong.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Description of reference numerals: 1, lamp housing；2, radiating tube；3, LED module radiator；4, Switching Power Supply；5, radiating fin.
Detailed description of the invention
See Fig. 1, a kind of heat sinking formula LED street lamp light fixture, include the radiating tube 2 of lamp housing 1 and O type, set in lamp housing 1
Being equipped with LED module radiator 3 and Switching Power Supply 4, lamp housing 1 is external to upper end and is provided with and is parallel to each other and equally spaced heat radiating fin
Sheet 5, the gap between each radiating fin 5 is 4mm～6mm, and it is internal to wrap up or tight that a part for radiating tube 2 is arranged at lamp housing 1
Being affixed on LED module radiator 3 and Switching Power Supply 4, radiating tube 2 another part is disposed through between each radiating fin 5,
To transfer heat to each radiating fin 5.
This utility model uses the radiating tube 2 running through lamp housing 1, and makes the bottom pipeline section parcel of radiating tube 2 or be attached to
Thermal source, and another part of radiating tube 2 passes lamp housing 1 and through between each radiating fin 5, it is achieved operationally, radiating tube 2
Internal heat is by distributing to greatest extent by each radiating fin 5, by making cross-ventilation heat radiation reach optimal radiating state.
