A kind of pair of passage of heat bulb lamp, include lamp holder, be connected to the driving power in lamp holder the place ahead, driving power is located in the radiating shell, the LED lamp plate that is distributed with a plurality of LED lamp pearls is installed in the top of radiating shell, diffuser is arranged on radiating shell the place ahead, LED lamp plate below is provided with an aluminium flake, forms annular groove on the side of this sheet, and the lateral wall of this annular groove is fitted on the radiating shell.

Be provided with a cavity volume for accommodating driving power in the described radiating shell, aluminium flake is the dish configuration of an indent, and the end face of its corresponding cavity volume in middle part raises up and forms the lug boss of a cylindricality, forms annular groove between the outer side edges of the aluminium flake of lug boss and dish-type.

Be equipped with a plurality of through holes on the upper plane of described lug boss with on the cavity volume end face.

Described cavity volume end face is provided with at least one locating hole, but and the lug boss of aluminium flake is provided with the hook portion that at least one buckle enters above-mentioned locating hole.

Described driving power is arranged in the insulation plastic.

After adopting said structure, bulb lamp of the present utility model is when work, the aluminium flake of a tool conductive force is set up in LED lamp plate below, and the edge of aluminium flake forms an annular groove, it is put above radiating shell, and the heat that the LED lamp plate is given out conducts in the radiating shell by aluminium flake, and transverse and longitudinal two directions in the radiating shell inner chamber form two passages of heat, can conduct on the radiating shell heat is multi-direction, thereby carry out efficiently radiates heat.

The specific embodiment

In order further to explain the technical solution of the utility model, the utility model is elaborated below by specific embodiment.

Extremely shown in Figure 5 such as Fig. 2, of the present utility model pair of passage of heat bulb lamp comprises lamp holder 1, and driving power 2 and radiating shell 3 are connected to the diffuser 4 of the sphere of radiating shell 3 front ends, and the LED lamp plate 5 that is installed in radiating shell 3 tops, be distributed with a plurality of LED lamp pearls 51 on the LED lamp plate 5.

Wherein, be distributed with metal threadedly on the outer surface of lamp holder 1, and partly be connected on the lamp holder 1 with the lamp body of driving power 2, driving power 2 is arranged among the insulation plastic 21, because driving power 2 is placed in the radiating shell 3, radiating shell 3 adopts the metal material of good heat dissipation effect, such as aluminum hull.In radiating shell 3, be provided with the cavity volume 31 of an accommodating driving power 2, be fixed in the radiating shell 3 thereby can make driving power 2 be inserted in, be connected and fixed between radiating shell 3 and the lamp holder 1.Diffuser 4 is installed in the place ahead of radiating shell 3, and lamp plate 5 then is fixed on the place, top of radiating shell 3, and LED lamp pearl 51 is distributed on the LED lamp plate 5, will be a LED bulb lamp behind each assembling parts.

The utility model is for increasing the heat conduction and heat radiation effect of LED, below the LED lamp plate, be provided with an aluminium flake 6, this aluminium flake 6 is the dish configuration of an indent, its corresponding cavity volume end face 311 in middle part raises up and forms the lug boss 61 of a cylindricality, this lug boss 61 is engaged on the top of cavity volume 31 in the radiating shell, and be provided with a plurality of through holes 611 on plane above the lug boss 61 corresponding with through hole 312 on the cavity volume end face 311, to guarantee the connection between the circuit, simultaneously, also can be provided with on the upper plane of lug boss 61 at least one hook portion 612, but thereby hook portion 612 buckles enter in the locating hole that cavity volume end face 311 is provided with the anti-fastener of aluminium flake in radiating shell 3.And formation one annular groove 63 between the outer side edges 62 of the aluminium flake 6 of lug boss 61 and dish-type, aluminium flake 6 is on being placed on radiating shell 3 time, 63 of this annular grooves are positioned at radiating shell 3 inner chambers top just, be provided with a cavity volume 31 in the inner chamber because of radiating shell 3, in radiating shell inside, cavity volume 31 outsides just form a heat radiation chamber 32, thereby annular groove 63 is located in the top in heat radiation chamber 32, and the lateral wall of annular groove 63 is fitted on the radiating shell 3, as shown in Figure 5, for the heat that LED lamp plate 5 gives out, can not only be by backward outer the distributing of radiating shell 3 downward conductings, owing to set up aluminium flake 6, the top in heat radiation chamber 31 is formed with annular groove 63, because of the conductive force of aluminium flake, the heat that LED lamp pearl 51 gives out can conduct on the aluminium flake 6 by heat, and aluminium flake 6 is formed with annular groove 63 above heat radiation chamber 32, heat can laterally import on the radiating shell, form two passages of heat, effectively increased heat-transfer rate, thereby can greatly strengthen radiating effect.
