Description
Technical field
It is the street lamp of light source with LED that the utility model relates to a kind of, is meant that especially a kind of fin is distributed in the lateral surface of lampshade and the LED road lamp cooling structure on the outer end face simultaneously.
Background technology
Street lamp is as the present very general road lighting field that is applied in of a kind of road lighting equipment, the general important view road of town road and city has all been installed various street lamp attractive in appearance now, and the planning of city illumination now all will be from embodying the angle of urban culture grade and region feature with construction.Various street lamps extensively are subject to people's attention under such social background.
General street lamp light source commonly used mainly should have good photocurrent versus light intensity and rational energy-saving effect, realizes that to reduce environmental pollution green illumination is a purpose.Therefore, be the long-life to the requirement of street lamp electric light source, high light efficiency has colour rendering and uniformity preferably, and can require has certain interchangeability when the maintenance bulb.And the most often metal vapors arc discharge lamp that uses in the city street lamp at present, such as with high-pressure sodium lamp, the high-pressure mercury lamp street lamp as lighting source, they have high light efficiency and colour rendering preferably, advantages such as long-life.But along with the progressive led light source of society as a kind of novel light source very general road lighting field that is applied in now; but led light source has the work caloric value of a lot of good characteristic led light sources than higher, if thereby solving bad heat dissipation problem can cause the led light source light decay seriously to influence the problem in service life usually.
With regard to the led light source radiating mode of present appearance, general all is the bottom that only fin is made in led light source, the heat that light source sends passes on the fin by aluminium base, such structural design in concrete the use, at first because its area of dissipation is little, thereby only be the situation that poor heat radiation can appear in the radiator heat-dissipation of aluminium base bottom, secondly, the lampshade of its whole light source is not an one, and the area of dissipation of whole lamp also can cause the situation of poor heat radiation inadequately greatly.And be the major defect of conventional art as mentioned above.
Summary of the invention
The utility model provides a kind of LED road lamp cooling structure, and the utility model dispels the heat simultaneously by the bottom surface and the side of adopting light source, under the feelings row of the whole same volume of lamp, make the area of dissipation of light source enough big, heat radiation is enough abundant, good heat dissipation effect, and this is a main purpose of the present utility model.
The utility model provides a kind of LED road lamp cooling structure, and its fin and whole lampshade are the designs of one, and except that the making full use of of area of dissipation, external form also can be more smooth, attractive in appearance, and this is an another purpose of the present utility model.
The technical scheme that the utility model adopted is: a kind of LED road lamp cooling structure, it comprises the connection base, lampshade and some fin, this lampshade is connected this connection base one end, some these fin are fixedly installed on this lampshade, and some these fin and this lampshade are connected to form an integral body, this lampshade has inner surface and outer surface, center on formation one lamp chamber by this inner surface, this inner surface comprises medial surface and inner top surface, this outer surface comprises lateral surface and outer end face, some fin are arranged on this outer surface that is connected this lampshade in proper order, each this fin all is connected this lateral surface of this outer surface simultaneously and is somebody's turn to do on the outer end face, this fin of the present utility model as mentioned above not only on this lateral surface of this lampshade and also be distributed in simultaneously this lampshade should outside on the end face so that whole lampshade all can be used as the radiator of light source, this fin so evenly distributes, more help flow air the heat on each fin is taken away the effect that reaches the lifting radiating effect, some these fin are parallel to each other and are connected on this outer surface of this lampshade.
Some led light sources are arranged in this lamp chamber of this lampshade, are provided with some joint pins in this lamp chamber of this lampshade, and each this joint pin all has the connection inclined-plane, and this led light source is arranged on this connection inclined-plane.
This joint pin has screw fixing hole, bottom surface and connects the side, screwed togather fixed screw in this screw fixing hole, this joint pin is arranged in this lamp chamber of this lampshade by this fixed screw, this bottom surface of this joint pin is connected on this inner top surface of this lampshade, and this connection side of this joint pin is connected on this medial surface of this lampshade.
The beneficial effects of the utility model are: this fin of the present utility model as mentioned above not only on this lateral surface of this lampshade and also be distributed in simultaneously this lampshade should outside on the end face so that whole lampshade all can be used as the radiator of light source, this fin so evenly distributes, and more helps flow air and the heat on each fin is taken away the purpose that reaches the lifting radiating effect.
