Be illustrated in figure 1 as the cutaway view of existing LED radiator, it has used the base material (cast aluminium radiator 7) of aluminum casting as heat radiation, but in order to prevent the current lead-through between inner cowling panel (rectifier 8) and the aluminum casting (cast aluminium radiator 7), so having increased a plastic bushing 6 in inside, it has come insulating effect, also be in order to prevent the current lead-through between socket (interface 10) and the aluminum casting (cast aluminium radiator 7) in addition, it has increased a plastic insulation ring 9 again and has come insulating effect in the bottom.In such structure, single heat sink assembly just has 3 structural members, the assembling procedure that also has securing member and match and answer, and the cost of LED descended bigger obstruction.
The utility model content
At the above-mentioned defective that prior art exists, technical problem to be solved in the utility model is to propose a kind of simple in structure, radiating effect better, safety coefficient is higher, cost is lower LED lamp with heat abstractor.
In order to solve above-mentioned technical problem of the present utility model, a kind of LED lamp that the utility model provides with heat abstractor, comprise lampshade, aluminium base lamp plate, radiator, rectifier, LED and lamp holder, a plurality of LED are connected in series and are electrically connected with rectifier, lamp holder, and radiator and lampshade interface joint are provided with binding agent; The fixedly connected lamp holder interface of lampshade interface, rectifier is placed in one; LED is welded on the aluminium base lamp plate, and aluminium base lamp plate one side fits tightly radiator; Radiator is arranged between lamp holder and the aluminium base lamp plate, and fixes with lamp holder and aluminium base lamp plate respectively; Its innovative point is, radiator constitutes thermosetting plastics member and aluminium inserts shot moulding by the thermosetting plastics member with as the aluminium inserts of heat radiating material; Aluminium base lamp plate is fixedlyed connected with the aluminium inserts by hold-down screw.
With respect to existing LED lamp, the utlity model has following characteristics and advantage with heat abstractor:
1) the utility model as the heat conduction pedestal, as the mould shot moulding that inserts is put into radiator, makes product component quantity reduce greatly it with the aluminium inserts, deducts at least 2 assembly processes, helps client's cost control and Material control.
2) because thermosetting plastics and two kinds of materials of aluminium inserts that the utility model radiator uses all are the higher materials of thermal conductivity factor, with be directly to contact between the heater (LED and rectifier), unlike there being plastic bushing to intercept in the middle of the existing radiator, so radiating effect is better.
3) the utility model radiator external member is a thermosetting plastics, so just stopped the possibility of current lead-through on the base reason, relatively prior art comes safety coefficient more reliable with plastic bushing and dead ring.
4) body of material of the utility model radiator use is a thermosetting plastics, so the weight ratio of product is light by 1/3rd with the aluminum component meeting of volume.
5) because the processing charges of mould of plastics, to add the existing heat spreader structures number of parts than cheap half the price of aluminium mold few, so on the expense of researching and developing, also be that cost has been had good control.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, further set forth the utility model.These embodiment be interpreted as only being used to the utility model is described and be not used in the restriction protection domain of the present utility model.After the content of having read the utility model record, those skilled in the art can make various changes or modifications the utility model, and these equivalences change and modification falls into the utility model claim institute restricted portion equally.
As shown in Figure 2, the LED lamp that the utility model one preferred embodiment provides with heat abstractor, comprise lampshade 21, aluminium base lamp plate, radiator, rectifier 27, LED22 and lamp holder (having interface 28 and contact 30), a plurality of LED22 are connected in series and are electrically connected with rectifier 27, lamp holder, and radiator and lampshade interface joint are provided with binding agent 24; The fixedly connected lamp holder interface 28 of lampshade 21 interfaces, rectifier 27 is placed in one; LED22 is welded on the aluminium base lamp plate, and aluminium base lamp plate one side fits tightly radiator; Radiator is arranged between lamp holder and the aluminium base lamp plate, and fixes with lamp holder and aluminium base lamp plate respectively; Radiator constitutes thermosetting plastics member 26 and 25 shot moulding of aluminium inserts by thermosetting plastics member 26 with as the aluminium inserts 25 of heat radiating material; Aluminium base lamp plate is fixedlyed connected with aluminium inserts 25 by hold-down screw 23.
Specify the radiating principle and the assembling process of the present utility model of the utility model radiator below in conjunction with accompanying drawing.
Radiating mode is meant the main mode of this heat sink radiates heat.In thermodynamics, heat radiation is exactly the heat transmission, and the transfer mode of heat mainly contains three kinds: heat conduction, thermal convection current and heat radiation.Material itself or when material contacts with material, the transmission of energy just are called as the heat conduction, and this is the most general a kind of thermaltransmission mode.In fact, the radiator of any kind all can use above three kinds of thermaltransmission modes basically simultaneously, just the emphasis difference.The employed principle of the radiator of present embodiment LED is exactly heat conduction and heat radiation, by aluminum inserts 25 heat that LED22 produced is passed on the thermosetting plastics member 26 by heat conducting mode earlier, thermosetting plastics member 26 distributes heat by thermal-radiating mode then.
Pass to the top of radiator when heat after, just need as soon as possible the heat that transmits to be dispersed in the surrounding enviroment to go, will carry out heat exchange with ambient air exactly radiator.At this moment, heat is to transmit between two kinds of different mediums, and the formula of being followed is Q=α X A X Δ T, and wherein Δ T is the temperature difference between two media, i.e. the temperature difference of radiator and ambient air; And α is the thermal conductivity factor of fluid, and after fin material and composition of air were determined, it was exactly a fixed value; Wherein most important A is the contact area of fin and air, under the constant prerequisite of other conditions, as the volume of radiator, all can limit to some extent, space in the light fixture is limited, cross the aesthetic property that conference influences light fixture, and by changing the shape of radiator, increase the contact area of itself and air, increasing heat exchange area, is the effective means that improves radiating efficiency.Realize this point, generally increase surface area by being aided with ways such as surface roughening or screw thread with the fin type design.We obtain the different thermal data that different size LED is distributed by test then, needing can obtain how many area of dissipations unnecessary heat could be distributed.Thereby design is equal to the radiator of area of dissipation.
Summarize above each point, so present embodiment thermosetting plastics member 26 designed radiator inside must have the inserts 25 of an aluminum sleeve, because during the moulding of thermosetting plastics radiator is to do the inserts injection moulding, so aluminum inserts 25 and thermosetting plastics member 26 in conjunction with the time very closely, put into rectifier 27 after the radiator moulding, then output on the rectifier is connected with input on the LED substrate, the two ends of the input of rectifier and screw interface 28 are to being connected, after forming the state of circuit circulation, LED substrate (being aluminium base lamp plate) is connected with aluminum inserts 25 usefulness screws 23, then the mode by some glue with 24 in adhesive in the groove of radiator lampshade assembling place, press lower lamp shade 21, make it the curing that is connected with radiator.Also put adhesive 29 at the screw interface place at last, the joint of screwing on, the assembling of whole LED is finished like this.
