Abstract
The utility model relates to an inserting piece type LED street lamp, comprising a lamp body, wherein the lamp body is provided with a lamp-post connecting piece and an LED driver and also comprises a flat-plate type aluminium heat sink; the front surface of the aluminium heat sink is parallelly provided with a plurality of dovetail grooves, in which dovetailing aluminium base plates matched with the dovetail grooves are inserted; the dovetailing aluminium base plates are distributed with LED light sources; the back surface of the aluminium heat sink is parallelly provided with a plurality of U-shaped grooves, on which aluminium finned plates are plugged; and the LED driver is connected with the LED light sources by conducting wires. The inserting piece type LED street lamp has the benefits that: (1) radiating fins are plugged on the lamp body, thus saving the mold opening expenses of the traditional die-casting process, and reducing the manufacture cost; (2) the number of the radiating fins is increased, thus increasing the radiating area, and having better radiating effect; and (3) the aluminium base plates are plugged on the aluminium heat sink, thus being convenient for disassembly.
Description
Technical field
The utility model relates to a kind of LED street lamp.
Background technology
Street lamp is as the illuminating product of a kind of garden, square and road, and its consumption is very huge.Existing civil power street lamp exists control inconvenience, effective luminous efficacy is not high, power consumption is big, the life-span is short, start and wait deficiency slowly, and is relative with it, and that the LED street lamp then has is energy-conservation, colourity good, fault is few, the advantage of life-span length.Chinese patent ZL200910106232.4 discloses a kind of LED street lamp, comprise the aluminium base that is provided with printed circuit, the front of aluminium base is provided with the LED lamp, reverse side has radiating fin, radiating fin and aluminium base integrally casting in the common process need to use special casting mould, thereby cost of manufacture are higher, and the fin pitch of making like this is more sparse, and radiating effect is good not enough.
Summary of the invention
In order to solve the problems referred to above that existing LED street lamp exists, the utility model provides that a kind of fin is plugged on the lamp body, the blade inserting LED street lamp of cost of manufacture reduction, good heat dissipation effect, easy accessibility.
The utility model adopts following technical scheme:
Blade inserting LED street lamp, comprise lamp body, lamp stand connector and led driver are housed on the described lamp body, described lamp body comprises flat Aluminum Heat Sink, and the front of the described Aluminum Heat Sink multiple tracks dovetail groove that be arranged in parallel is inserted with the aluminium base of the dovetail type that cooperates with it in the described dovetail groove, be laid with led light source on the described aluminium base, the back side of described Aluminum Heat Sink is arranged with multiple tracks U type groove in parallel, is plugged with the aluminium fin keel on the described U type groove, and described led driver is connected by lead with described led light source.
Preferably, described led light source is the high-power surface welded LED of 1W.
Preferably, described lamp stand connector is the lamp stand folder.
Technical conceive of the present utility model is: by the Aluminum Heat Sink back side at lamp body U type groove is set, radiating fin is plugged on this U type groove, make the two combine closely into the heat radiation main body by mechanical presses, also promptly adopt the inserted sheet technology generations for traditional extrusion process, saved the integrally manufactured required die sinking expense of Aluminum Heat Sink and radiating fin, cost declines to a great extent, and, the more crypto set that to make of the aluminium fin of Zhi Zuoing in this way, area of dissipation can significantly increase, thereby has strengthened heat-sinking capability greatly.In addition, be provided with some dovetail grooves in the front of Aluminum Heat Sink, the strip aluminium base that is furnished with led light source is plugged in the described dovetail groove and closely contact, and like this, dismounting is very convenient, and radiating effect might as well.
The beneficial effects of the utility model are: (1) radiating fin is plugged on the lamp body, saved the die sinking expense of traditional extrusion process, cost of manufacture reduces; (2) the radiating fin number increases, so the area of dissipation increase, and radiating effect is better; (3) aluminium base is plugged on the Aluminum Heat Sink, easy accessibility.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
With reference to Fig. 1: blade inserting LED street lamp, comprise lamp body, lamp stand connector and led driver are housed on the described lamp body, described lamp stand connector is a lamp stand folder 6, described lamp body comprises flat Aluminum Heat Sink 1, the front of the described Aluminum Heat Sink multiple tracks dovetail groove 12 that be arranged in parallel, be inserted with the aluminium base 2 of the dovetail type that cooperates with it in the described dovetail groove 12, the edge of aluminium base 2 closely contacts so that dispel the heat with dovetail groove 12, be laid with led light source 4 on the described aluminium base, the back side of described Aluminum Heat Sink is arranged with multiple tracks U type groove in parallel, be plugged with aluminium fin keel 10 on the described U type groove, making the root of aluminium fin 10 and Aluminum Heat Sink 1 combine closely by mechanical presses becomes the heat radiation main body, and described led driver 7 is connected by lead 8 with described led light source 4.
In the present embodiment, described lamp body also comprises the side plate 5 of both sides, the end plate 11 at two ends, and the top board 9 that is positioned at aluminium fin 10 back sides, and this top board 9 is connected between the two end plates 11, with aluminium fin 10 back sides certain distance is arranged, so that the heat radiation of aluminium fin 10.Led driver 7 is arranged on the top board 9 with lamp stand folder 6.The top of side plate 5 and end plate 11 also is equipped with glass plate 3.Described Aluminum Heat Sink 1 is connected on the groove of biside plate 5 inboards, and insert in the two end plates 11 at its two ends.
Present embodiment, described led light source 4 is the high-power surface welded LED of 1W.This led light source 4 adopts the Surface Mount mode to be welded on the aluminium base 2 of strip and band printed wire, and power is not less than 60W.
This programme is provided with U type groove by the Aluminum Heat Sink back side at lamp body, radiating fin is plugged on this U type groove, make the two combine closely into the heat radiation main body by mechanical presses, adopt the inserted sheet technology generations, saved the integrally manufactured required die sinking expense of Aluminum Heat Sink and radiating fin for traditional extrusion process, cost declines to a great extent, and the more crypto set that can make of the aluminium fin of Zhi Zuoing in this way is because quantity increases, area of dissipation can significantly increase, thereby has strengthened heat-sinking capability greatly.In addition, be provided with some dovetail grooves in the front of Aluminum Heat Sink, the strip aluminium base that is furnished with led light source is plugged in the described dovetail groove and closely contact, and like this, dismounting is very convenient, and radiating effect might as well.
