Description

A kind of spliced street lamp heat radiator

Technical field

The utility model is related to a kind of radiator, and in particular to a kind of spliced street lamp heat radiator.

Background technology

LED street lamp on the market at present, light can not regulate and control, therefore according to great power LED to meet overcast and rainy, haze sky The intensity of light of gas, power wastage is then caused under the preferable environment of visibility；According to the relatively low LED of power, then in wet weather Under the environment of the visibility such as it difference, it is impossible to meet light intensity demand.

LED is electroluminescent device simultaneously, and the electric energy for there was only 15%~25% in its course of work changes into luminous energy, remaining Electric energy be nearly all converted into heat energy, raise LED temperature, cause light efficiency drastically to decline.If temperature is too high, LED will be because Overheat and damage.The radiating of LED street lamp is to need one of key problems-solving, when being not only directly connected to LED real works Luminous efficiency, and because LED street lamp brightness requirement is high, caloric value is big, and outdoor this use environment is harsher, If radiating is bad to directly result in LED quick agings, stability reduction.

Existing LED street lamp radiator is designed as integral die-cast mostly, and the fin of this mode can not be according to actual hair Enthusiasm condition carries out most rational design, and radiating effect is poor；And in maintenance, because lamp bead is also to use integral layout, maintenance adopts With integral replacing, maintenance cost height.

Utility model content

In order to solve the above problems, a kind of heat sink design of the utility model offer is reasonable, the spelling for the lamp bead that can independently arrange Connect formula street lamp heat radiator.

The utility model solves the technical scheme that its technical problem used：A kind of spliced street lamp heat radiator, including The heat sink of at least two pieces integral cold forgings, heat sink mutually splices, and the end face of its same side is provided with radiating fin.

Further, radiating fin is flake structure or composite stud structure.

Further, heat sink includes the first heat sink, the second heat sink and the 3rd heat sink；First heat sink, second Heat sink symmetrically connects the 3rd heat sink both sides, and the first heat sink, the second heat sink and the 3rd same side end face of heat sink are set There is radiating fin.

Further, the first heat sink, the radiating fin on the second heat sink are that cross section is heart-shaped cylinder；3rd dissipates Radiating fin on hot plate is rectangular tab.

Further, in addition to a connecting plate, connecting plate one end connection heat sink, and being provided with the same side of radiating fin Card article is installed.

Further, another side end face relative in radiating fin of heat sink is provided with lamp bead.

Further, heat sink is using soldering connection or close-fitting connection or rivets.

Further, the junction of heat sink carries out water-proofing treatment.

Further, heat sink is made of the integral cold forging of fine aluminium.

The beneficial effects of the utility model are：First, heat sink uses connecting method, and every block of heat sink can be individually equipped with Lamp source, it is independent to be independently controlled as a lamp, it is more energy efficient, more scientific；Second, used in addition using cold forging integrated technique It is pure aluminum material, same wattage is lightweight, good heat dissipation effect；3rd, it can be concentrated according to actual heat, carry out the knot of fin Structure is designed, and reaches more preferable radiating effect；4th, maintenance when, can according to bad point position, be individually replaced a certain piece of fin and Lamp source, without integral replacing, has saved maintenance cost.

Brief description of the drawings

The utility model is further illustrated with reference to the accompanying drawings and examples：

Embodiment

Embodiment 1

1~Fig. 3 of reference picture, the utility model is a kind of spliced street lamp heat radiator, including using the integral cold forging of fine aluminium The first heat sink 1, the second heat sink 2, the 3rd heat sink 3 and the connecting plate 5 being made, the first heat sink 1 and the second heat sink 2 The both sides of the 3rd heat sink 3 symmetrically are connected to, connection herein can use soldering, close-fitting or riveting, the present embodiment specifically uses soldering Connection, and carry out water-proofing treatment in junction；3rd heat sink 3 is provided in round hardened structure, the radiating of the first heat sink 1, second Plate 2 is correspondingly arranged to surround the circular arc plate of the 3rd heat sink 3；The first heat sink 1, the second heat sink 2 and the 3rd dissipate simultaneously Hot plate 3 is provided with radiating fin 4 in same side end face, wherein the radiating fin 4 of the first heat sink 1, the second heat sink 2 is uniformly to set The cross section put is heart-shaped cylinder, and the radiating fin 4 of the 3rd heat sink 3 is arranged to rectangular thin plate, inner ring in outer ring and is arranged to Cross section is heart-shaped cylinder；The one end of connecting plate 5 connects the first heat sink 1, the second heat sink 2, and same in radiating fin 4 Side connects identical with above-mentioned connected mode provided with card article 6 is installed, herein, and carries out water-proofing treatment.

A kind of spliced street lamp heat radiator of the present embodiment, can be in the first heat sink 1, the second heat sink 2, the 3rd heat sink 3 and another independently installed lamp source in side end face corresponding with radiating fin 4 of connecting plate 5, it is independently controlled, so can be according to four Season visibility change, carry out rational lamp source control, it is to avoid cause that power wastage or street lamp light intensity are weak, can not meet and use need The problem of asking.

Meanwhile, a kind of spliced street lamp heat radiator of the present embodiment, each several part is made of the integral cold forging of fine aluminium, is radiated The structure of fin 4, layout can be designed according to actual use demand, and because of integral die-cast heat radiating fin is limited in the absence of traditional Structure, the layout of piece 4, reach more preferable radiating efficiency；And weight is dramatically reduced, light pole, casing of street lamp is reduced Support pressure；And in maintenance, integral replacing is not required to, bad point position need to be only directed to, is individually replaced on a certain splicing block Lamp source or the splicing block changed together with lamp source, significantly reduce maintenance cost.
