Abstract
The utility model discloses a side heat dissipation structure of LED streetlight comprising a streetlight body, a LED light source disposed on the streetlight body, and a power source, a plurality of dissipation bodies disposed on two sides of the streetlight. The dissipation bodies are built by overlapping a plurality of arc dissipation sheets in sequential order, and the dissipation sheets extend from the top of streetlight body to the end, besides, gap is arranged between adjacent dissipation sheets. In the utility model, dissipation bodies are disposed on two sides of the streetlight body and integrated with the whole light body, the LED light source is directly fixed on the light body, thereby the heat can be led out by the dissipation bodies in time. Because the dissipation bodies are built by overlapping a plurality of arc dissipation sheets in sequential order, the water is not able to pond in the dissipation bodies, the streetlight can not be broken, and the working stability of the streetlights can be improved. Compared with the prior arts, the utility model has advantages of good dissipation effect, good working stability and the like.
Description
Technical field
The utility model relates to the LED street lamp, particularly be a kind of LED street lamp side radiator structure.
Background technology
At present the city require street lamp bright lamp rate more than 98%, if the street lamp cisco unity malfunction not only influences the image in city, also can cause the traffic safety accident.Road lighting lamp is to use the lamp that the time is the longest and power consumption is maximum, and the luminescent device that general street lamp adopts is a bulb, and it has, and power consumption is big, service life is short, heating is serious and shortcomings such as illuminating effect difference.
In order to alleviate the urban electric power energy scarcity, to save national energy, gradually adopt now that power consumption is little, long service life, voltage is low, electric current is little high-powered LED lamp replace original bulb, but because high-powered LED lamp is when luminous, can produce a large amount of heat, if can not in time dispel the heat, then may cause the LED lamp to damage, influence road lighting.
Existing LED radiator structure is generally integral body, its heat radiation is mainly dispelled the heat from the top by the aluminium base heat sink that is connected with led light source, and the radiating effect of this radiator structure is limited, and when running into thunderstorm weather, rainwater can enter in the street lamp from the top, causes street lamp to damage.
Summary of the invention
For this reason, the purpose of this utility model is to provide a kind of LED street lamp side radiator structure, and is not good and be easy to generate problems such as fault to solve radiating effect that present LED street lamp is run into.
For achieving the above object, the utility model is mainly by the following technical solutions:
A kind of LED street lamp side radiator structure, comprise road lamp body (1), be installed in led light source (2) and power supply (7) on the road lamp body (1), described road lamp body (1) both sides are provided with a plurality of radiators (3), described radiator (3) is by a plurality of arc fin (102) formation that superposes successively, this arc fin (102) is extended to the bottom by road lamp body (1) top, and faces fin mutually and be provided with the space between (102).
Wherein said road lamp body (1) bottom center is provided with fixing hole (101), and described led light source (2) is fixedly mounted in this fixing hole (101).
Wherein said road lamp body (1) both sides, bottom surface are provided with draw-in groove (104), and inlay card has lampshade (6) in this draw-in groove (104).
Wherein said road lamp body (1) top is provided with cavity (103).
The utility model is by being provided with radiator in the road lamp body both sides, and radiator and whole lamp body are one, and led light source directly is fixedly mounted on the lamp body, therefore the heat that produces can in time be derived by radiator, in addition because radiator is to be superposeed successively by a plurality of arc fin that extend to the bottom from the lamp body top to constitute, therefore can in radiator, not produce ponding, avoid the problem of street lamp damage, improve the job stability of street lamp.Compared with prior art, the utlity model has good heat dissipation effect, advantages such as good operating stability.
