Abstract
The utility model relate to a LED street lamp bracket possessing a lamp bracket body. The lamp bracket body possesses a bearing surface for installing LED assemblies; two installation parts used for installing end plates are moulded on a back side of the bearing surface and heat dissipation fins parallel to the installation parts are moulded on both inner and outer sides of the two installation parts, wherein a first cover plate is installed between the two installation parts; the installation parts and the heat dissipation fins perpendicularly form a plurality of interval grooves, i.e. the installation parts and the heat dissipation fins are arranged at intervals in a length direction. Accordingly, air convection in perpendicular directions can be strengthened under the condition that heat dissipation areas are not reduced so as to enhance heat dissipation effects. The LED street lamp bracket has a simple structure; the lamp bracket body is made of aluminium alloy materials and has the characteristics of a small size, light quality, a large heat dissipation area, good heat dissipation effects and dust prevention; a whole anti-corrosive property of the lamp bracket y is improved and a service life of the LED street lamp bracket is effectively prolonged.
Description
Technical field:
The utility model relates to technical field of lamps, refers in particular to a kind of LED street lamp lamp bracket.
Background technology:
Existing general LED street lamp lamp bracket normally is made up of upper shell and lower house; Form certain installing space between the upper and lower casing to arrange assemblies such as LED module, driving power; Usually only at the outside moulding radiating fin of upper shell, the lower house window is with printing opacity and assemblies such as reflection shield, glass are installed.Such street lamp lamp bracket structure is comparatively complicated, and the installation of assemblies such as assembling and LED module is inconvenience comparatively, also is not easy to the maintenance and the replacing of street lamp; And; Radiating fin mainly is arranged on the outside of upper shell, and is comparatively concentrated, and radiating effect is not best comparatively speaking; And fin is many and upper shell vertically upward; The slit that is directly exposed between the outer fin is located to be difficult under easy dust stratification and the natural conditions to remove, and therefore influences the radiating effect of lamp bracket more easily, and the corrosion of lamp bracket especially fin is also deepened easily.
The utility model content:
The purpose of the utility model is to overcome the weak point of prior art, and a kind of new LED street lamp lamp bracket is provided.
The utility model realizes that the technical scheme that its purpose adopts is: a kind of LED street lamp lamp bracket; Has a lamp bracket body; Said lamp bracket body has the loading end of an installation LED assembly; Form two installation portions that are used to install end plate in the back side of this loading end, and all form the radiating fin parallel, wherein: between said two installation portions, first cover plate is installed with said installation portion in the interior outside of two installation portions; And said installation portion and radiating fin have been vertically formed some interval troughs, and promptly said installation portion and radiating fin are the discontinuous setting in the longitudinal direction.
Radiating fin top in the two installation portions outside is equipped with second cover plate.
Said first cover plate, second cover plate are socketed in the cylinder cutting of moulding on said installation portion and the radiating fin through the cylindrical pocket that is provided with above that respectively along its length.
Said radiating fin is the height alternating expression to be arranged, and its surface all is ripple type.
Described first cover plate is arc surfaced, and also undulate of its outer surface.
The utility model passes through said structure; At first; Be vertically formed some interval troughs at said installation portion and radiating fin, promptly installation portion and radiating fin are the discontinuous layout in the longitudinal direction, can be under the situation that does not reduce area of dissipation; Strengthen the cross-ventilation of vertical direction, thereby strengthen radiating effect; Secondly; On the top of installation portion and radiating fin first cover plate, second cover plate are installed respectively; Utilize two installation portions and first cover plate and two end plates to form installing space, be used for arranging assemblies such as driving power, and utilize the gap between second cover plate and the radiating fin; Can effectively utilize the principle of hot nest stream, reach better radiating effect; And can effectively prevent dust stratification between surface and the radiating fin of radiating fin, and help keeping the radiating fin surface cleaning, guarantee that heat radiation is normal.
Description of drawings:
Fig. 1 is the perspective view of the utility model lamp bracket body;
Fig. 2, Fig. 3 are that the lamp bracket body installs first cover plate, the second structure of cover plate sketch map;
Fig. 4 is the structural representation of the another kind of application implementation example of the utility model.
The specific embodiment:
Below in conjunction with specific embodiment and accompanying drawing the utility model is further specified.
Shown in Fig. 1～3, the described LED street lamp of the utility model lamp bracket has a lamp bracket body 1; Said lamp bracket body 1 has the loading end 10 of an installation LED assembly; Along on the length direction of lamp bracket body 1, form two installation portions 11 that are used to install end plate in the back side of this loading end 10, and all form the radiating fin 12 parallel in the interior outside of two installation portions 11 with said installation portion 11; Wherein, Between said two installation portions 11, first cover plate 2 is installed, utilizes two installation portions 11 and first cover plate 2 to form installing space, be used for arranging assemblies such as driving power with two end plates; And said installation portion 11 and radiating fin 12 have been vertically formed some interval troughs 13; Be that said installation portion 11 and radiating fin 12 are discontinuous in the longitudinal direction; Through said vertical interval trough 13; Can under the situation that does not reduce area of dissipation, strengthen the cross-ventilation of vertical direction, thereby strengthen radiating effect.The number of interval trough 13 can be according to the design of concrete needs, has 12 interval troughs in for example embodiment illustrated in fig. 1, and has 5 interval troughs in embodiment illustrated in fig. 4.
Radiating fin 12 tops in two installation portions, 11 outsides are equipped with second cover plate 3; Particularly; Said first cover plate 2, second cover plate 3 are transplanted a cutting in 100 through cylinder that above that cylindrical pocket 20 is socketed in moulding on said installation portion 11 and the radiating fin 12 along its length is set respectively; The mode of pegging graft is simple in structure, installation and removal are all very convenient, and contact area is big, contact is tight, improves heat conduction efficiency; Utilize the heat-dissipating space that forms between second cover plate 3 and the radiating fin 12, can effectively utilize the principle of hot nest stream, reach better radiating effect.
In addition, said radiating fin 12 is the height alternating expression to be arranged, and its surface all is ripple type; Installation portion 11 surfaces also are ripple type; Described first cover plate 2 is arc surfaced, and also undulate of its outer surface, and the radiating fin of height interlaced arrangement can increase cross-ventilation and heat-dissipating space; And good looking appearance, adopt the ripple type surface can make area of dissipation maximization as far as possible.
In sum, the utility model is simple in structure, and lamp bracket body 1 adopts aluminum alloy materials to make, the little light weight of volume, and area of dissipation is big, good heat dissipation effect, and can prevent dust, the whole anti-corrosive properties of lamp bracket are improved, and can effectively prolong the service life of LED street lamp.
