Abstract
The utility model discloses a high-efficiency radiating LED (light-emitting diode) lamp in the field of illumination lamps. The LED lamp comprises a lamp cup radiator, wherein a lamp cap used for pairing mounting with a lamp holder is arranged at the bottom of the lamp cup radiator; the lamp cup radiator consists of an insulating plastic housing and a hardware piece located on an inner layer of the insulating plastic housing; a gap is reserved between the insulating plastic housing and the hardware piece, and filled with a high heat conductivity glue layer; the front of the high heat conductivity glue layer is clung to the surface of the inner layer of the insulating plastic housing; and the back of the high heat conductivity glue layer is clung to the surface of an outer layer of the hardware piece. The gap is filled with the high heat conductivity glue layer in a sealing manner, so that the lamp cup radiator can better transfer heat from inside to outside, and the radiating performance of the LED lamp is improved; and compared with the traditional lamp cup radiator, the LED lamp is lighter in weight, lower in cost and more compact in structure.
Description
Technical field
The utility model relates to field of illuminating lamps, particularly relates to a kind of LED lamp of high efficiency and heat radiation.
background technology
LED light fixture is as a part for low-carbon (LC) life at present, and its good low-power, lower calorific value performance have replaced the light fixture of other type gradually.On market, occur that heat radiation is taking major metal, pottery, heat radiation plastics as main, its heat dispersion mainly dispels the heat by heat transmission, and heat dispersion is limited.
Existing LED bulb all adopts the radiator of Lamp cup shape, can also play good thermolysis for serving as lamp body when.In order to increase the security of LED bulb, need to be provided with insulated plastic glue-line at the outer surface of radiator, insulated plastic glue-line inside is metallic radiating layer.In whole manufacturing process, insulated plastic glue-line and metallic radiating layer carry out injection moulding together with often, cause product percent of pass not high, and cost is also high simultaneously.Or adopt and first carry out, after the injection moulding of insulated plastic glue-line, metallic radiating layer is then installed again, will cause like this metallic radiating layer to contact imprecision with plastic layer, conduct heat bad.If this problem be mustn't go to solution, will inevitably have influence on promoting the use of of LED bulb.
Utility model content
The purpose of this utility model is to solve above defect, provides a kind of radiating effect good, the LED lamp that can conduct heat better.
The purpose of this utility model is achieved in the following ways:
A kind of LED lamp of high efficiency and heat radiation, comprise Lamp cup radiator, the top of Lamp cup radiator is the big opening end with support platform, the bottom of Lamp cup radiator be provided with for the lamp holder of lamp socket mounted in pairing mode, support platform surface at Lamp cup radiator big opening end is laterally provided with aluminium base, the surface soldered of aluminium base has several LED lamp pearls, and the bottom of aluminium base is provided with the LED driving power being electrically connected with lamp holder, and is fixed with lampshade at the big opening end edge of Lamp cup radiator.
For the security performance of production control cost and increase product, this Lamp cup radiator is made up of with the handware that is positioned at insulation plastic shell internal layer the plastic shell that insulate, and between insulation plastic shell and handware, leaves gap.And in this gap, be filled with high-heat-conductivity glue layer, and the internal layer surface of the plastic shell that insulate is close in the front of this high-heat-conductivity glue layer, and the reverse side of this high-heat-conductivity glue layer is close to the superficies of handware.By being filled with high-heat-conductivity glue layer, the plastic shell that makes to insulate contacts tighter with handware, do not have any gap, and heat conductivility is better.
As preferred scheme, the surface uniform of described insulation plastic shell is provided with integrated fin-shaped fin.Can increase area of dissipation, improve radiating effect.
As preferred scheme, described lampshade bottom edge is provided with buckle, and the big opening end edge of Lamp cup radiator is provided with the draw-in groove fastening with buckle pairing.
As preferred scheme, the external shape of described insulation plastic shell and handware is identical.
The beneficial effect that the utility model produces is: be filled with high-heat-conductivity glue layer by sealing in gap, Lamp cup radiator can be conducted heat from interior better outward, thereby improve the heat dispersion of LED lamp, simultaneously compared with traditional Lamp cup radiator, qualification rate is higher, weight is lighter, and cost is lower, and structure is tightr.
