Description

Fixing formula LED street lamp

Technical field

The utility model is about a kind of LED street lamp, especially in regard to a kind of LED street lamp of assembling with snap fit.

Background technology

Present LED street lamp becomes the main flow illumination gradually and uses street lamp, mainly is because it has advantages such as low-power consumption, power saving, has therefore begun progressively new and old money street lamp at present; Yet though the LED street lamp has power saving effect at present, its high heat problem is still the problem of numerous manufacturers headache, is main heat dissipation technology means to add large-scale heat sink at present, and the problem of many assemblings of also deriving below is an example.

At first seeing also shown in Figure 6ly, is an existing LED street lamp, and it includes:

One loam cake 50, the outer horizontal expansion one lamp stand sleeve pipe 51 of side direction thereafter, and be bent into wing plate 52 downwards in the left and right sides, form perforation 521 on each wing plate 52;

One lower cover 60, its left and right sides upwards is bent into fin 61, and the perforation 521 of two wing plates 52 of corresponding loam cake is formed with hole 611 equally, be covered on the below of loam cake 50 when the lower cover correspondence, the hole 611 of fin 61 is promptly aimed at the perforation 521 of loam cake wing plate 52, and passes hole 611 and bore a hole 521 with screw 80, is screwed togather loam cake 50 and lower cover 60 fixing, the surface of lower cover 60 is equipped with a plurality of lamp holes 612 again, and is formed with screw 613 near lamp hole 612 again; And

One led module 70 is located between loam cake 50 and the lower cover 60, and it includes a plurality of parallel LED lamp bars 71, each LED lamp bar 71 is a hollow metal bar 711, its bottom surface is embedded with a plurality of LED assemblies 712, makes LED assembly 712 corresponding lower cover lamp holes 612, and LED light is appeared from lower cover 60 lamp holes 612; The corresponding screw in each LED lamp bar 71 bottom surface 613 places are locked in LED lamp bar 71 on the lower cover 60 with screw 713 more again.

As shown in the above description, the screw-in version that adopts the led module of LED street lamp covers under being fixed in, and the annexation between lower cover and the loam cake adopts screw-in version, because the LED street lamp must be arranged at the open air for a long time, only to screw togather fixed form merely, may become flexible for a long time and come off, best bond strength can't be provided, except running maintenance possibly, the possibility that might endanger public security also; In addition, with regard to also quite time-consuming on the overall package; So present LED street lamp needs more reliable bond strength to reach more timesaving assembling mode.

The utility model content

Because existing LED street lamp member is many, bonding strength is not good between each member, and the utility model main purpose is to propose a kind of fixing formula LED street lamp, and except that having better bond strength, it is easy also quite to save time in the assembling.

Desiring to reach the employed major technique means of above-mentioned purpose is that described fixing formula LED street lamp is included:

One radiating fin is offered a lamp hole in the middle of it, and upper surface is formed with first chute, and lower surface then forms a plurality of vent ribs;

One led module is fixed in described radiating fin lamp hole place, and light is appeared downwards by lamp hole;

One pedestal, first chute of the corresponding radiating fin of its lower surface is formed with first draw runner, makes radiating fin be connected in the pedestal lower surface together with described led module, and described pedestal upper surface then is formed with one second chute; And

One sleeve pipe group, corresponding pedestal second chute in its bottom surface has extended to form second draw runner, to be fastened in pedestal upper surface, to supply lamp stand to plug and is fixed in wherein.

From the above, it is fixing that the utility model mainly makes pedestal, radiating fin and sleeve pipe group assemble in the engaging mode, existing bigger with the bonding area of single-point fixed form, and more firm bond strength is provided relatively, improves the life-span of LED street lamp; In addition, establishing assembling mode with cunning is that assembler provides more convenient timesaving operation procedure.
