Abstract

The utility model relates to a street lamp structure with dense heat dissipation holes. The street lamp structure comprises a front shell, a rear heat dissipation cover, a power box and a lens. The rear heat dissipation cover is arranged on the back face of the front shell, a heat dissipation plate rack is arranged on the inner side of the rear heat dissipation cover, the exterior of the heat dissipation plate rack is provided with a fixing end face and fixedly connected with the power box through the fixing end face, the heat dissipation plate rack is fixedly connected with the front shell through a plurality of heat dissipation fins with crossed clamping openings, and then a heat radiation structure with the several rhombic dense heat dissipation holes is formed, wherein the rhombic dense heat dissipation holes are respectively formed by four heat dissipation fins with the crossed clamping openings in a splicing and enclosing mode. The lens is arranged in the center of the front shell, and a plurality of luminous sources are installed below the lens. The street lamp structure has the advantages that the structure that a plurality of heat dissipation fins are evenly arranged on the upper surface of a heat dissipater is replaced by the heat radiation structure with the rhombic dense heat dissipation holes formed by the inclined heat dissipation fins with the crossed clamping openings in a crossing mode, so that the contact area between the heat dissipater and the air is increased, the heat dissipation speed is high, and the service life of products is long.

Description

A kind of lamp post structure with intensive louvre

Technical field

The utility model relates to field of illuminating lamps, relates in particular to a kind of lamp post structure with intensive louvre.

Background technology

Street lamp, with out of doors, be accomplished waterproof and dustproof, so light fixture must seal, LED continuous operation in the environment of high temperature, does not carry out if LED street lamp dispels the heat, and light fixture is serious with regard to as easy as rolling off a log evil idea or light decay.At present, the heat dissipation problem of domestic high-power LED street lamp does not solve yet completely, and product follow-up maintenance cost must increase.The LED lamp of prior art need to adopt radiator to dispel the heat conventionally, and its radiating mode mainly contains Natural Heat Convection, installs fan forced heat radiation additional, heat pipe and loop heat pipe heat radiation etc., if fin heat radiation, limited because of surface area, effect is bad equally.Meanwhile, the core component of LED lamp is encapsulating structure, generally comprises LED chip and cooling base, and chip is simultaneously attached at cooling base, and another side is luminous.Along with heat dissipation problem more and more comes into one's own, heat dissipation design has directly determined life-span, performance, cost of LED lamp etc., the same for street lamp, a lot of like products arrange heat radiation scale structure at positions such as bonnet, lampshades, by utilizing the gap between adjacent scale, dispel the heat, this traditional structure is unfavorable for engaging of radiator and air contact-making surface, and radiating rate is slower.Therefore,, for above aspect, need to carry out rational modification to prior art.

Utility model content

For above defect, the utility model provides a kind of and is conducive to reduce production costs, radiator and air contact-making surface increases, radiating rate is fast, the lamp post structure with intensive louvre of long product lifecycle, to solve many deficiencies of prior art.

For achieving the above object, the utility model is by the following technical solutions:

A kind of lamp post structure with intensive louvre, comprise front shroud, heat radiation bonnet, power pack, lens, the described front shroud back side is equipped with heat radiation bonnet and is positioned at heat radiation bonnet inboard heat radiation grillage is housed, this heat radiation grillage external belt has fixedly end face and is fixedly connected with power pack by this end face, between this heat radiation grillage and front shroud, by some bands, intersecting the fin of bayonet socket is fixedly connected with, the oblique mutual intersection of these fin, composition is with the radiator structure of some rhombus concentrated type louvres, each rhombus concentrated type louvre is surrounded by the fin splicing of four band intersection bayonet sockets, simultaneously, described front shroud center is equipped with lens and in lens below, some light emitting sources is installed,

Correspondingly, between described heat radiation grillage outer face and power pack with joint pin.

It is all one-body molded by mould that described band intersects fin and heat radiation bonnet, the power pack of bayonet socket, between described heat radiation honeycomb hole and front shroud with pressing from both sides chamber.

The beneficial effect of the lamp post structure with intensive louvre described in the utility model is: improved conventional road lamp bonnet and fitting structure of radiating fin, radiator upper surface is evenly arranged to some heat radiation scales to be changed to and by some oblique bands, intersects the fin of bayonet sockets and intersect the radiator structure of the intensive louvre of rhombus that forms, therefore radiator and air contact-making surface increase, radiating rate is fast, long product lifecycle, compare the structure of heat radiation scale, can reduce installation procedure, save and install manually.

Accompanying drawing explanation

With reference to the accompanying drawings the utility model is described in further detail below.

Fig. 1 is with the lamp post structure schematic diagram of intensive louvre described in the utility model embodiment;

Fig. 2 is with the schematic rear view of the lamp post structure of intensive louvre described in the utility model embodiment.

In figure:

1, front shroud; 2, heat radiation bonnet; 3, power pack; 4, lens; 5, light emitting source; 21, heat radiation grillage; 22, rhombus concentrated type louvre; 23, the fin of band intersection bayonet socket.

The specific embodiment

As shown in Figure 1-2, the lamp post structure with intensive louvre described in the utility model embodiment, comprise front shroud 1, heat radiation bonnet 2, power pack 3, lens 4, described front shroud 1 back side is equipped with heat radiation bonnet 2 and is positioned at heat radiation bonnet 2 inboards heat radiation grillage 21 is housed, these heat radiation grillage 21 outsides are fixedly connected with power pack 3 with stiff end face and by this end face, between this heat radiation grillage 21 and front shroud 1, by some bands, intersecting the fin 23 of bayonet socket is fixedly connected with, these are with the oblique mutual intersection of fin 23 of intersection bayonet sockets and fix by bayonet socket separately, thereby form the radiator structure with some rhombus concentrated type louvres 22, each rhombus concentrated type louvre 22 is surrounded by fin 23 splicings of four band intersection bayonet sockets, the fin 23 of these band intersection bayonet sockets and heat radiation bonnet 2, power pack 3 is all one-body molded by mould, simultaneously, described front shroud 1 center is equipped with lens 4 and in lens 4 belows, some light emitting sources 5 is installed,

Correspondingly, between described heat radiation grillage 21 outer faces and power pack 3, with joint pin and by bolt, be fixedly connected with power pack 3, between rhombus concentrated type louvre 22 wherein and front shroud 1 with folder chamber.

Above embodiment is the more preferably specific embodiment a kind of of the utility model, and the common variation that those skilled in the art carry out within the scope of the technical program and replacing should be included in protection domain of the present utility model.
