Abstract

An LED lamp having a novel heat dissipating structure comprises a plastic support, a ceramic heat dissipating shell, and an LED light source module set composed of a substrate and LED lamp beads. The LED lamp further comprises a metal connecting piece which is provided with a horizontal edge and bended edges. The horizontal edge closely contacts with the substrate horizontally, while the bended edges closely contact with the side wall of the ceramic heat dissipating shell. The LED lamp is simple in structure, saved in manufacture cost, good in heat dissipating effect, prolonged in service life, and high in cost performance. The lamp having the same size and adopting the technical scheme is greatly increased in power in comparison with a commonly used ceramic LED lamp.

Description

A kind of LED light fixture of radiating structure
Technical field
The utility model relates to a kind of LED light fixture of radiating structure.
Background technology
LED, when work, can give out a large amount of heats, and power is larger, and the heat distributing is just more, and this has limited the lifting of its power.Common LED light fixture adopts LED lamp pearl is fitted in and is in the aluminium base of horizontal plane or a side of ceramic substrate in the market, because substrate should not bend, the thickening so ceramic heat-dissipating housing can only be extended, the laminating that makes its inner side to be also horizontal plane with the opposite side of substrate contacts, the heat giving out on LED lamp pearl the most at last externally radiate by radiating shell, specifically as shown in Figure 1, but there is an obvious defect in this radiating mode, that is: heat-transfer path is long, there is bottleneck in effective diffusion transmission of heat, particularly it, when the amount of heat that the work of LED lamp pearl produces is passed to after ceramic heat-dissipating housing by substrate, although the smooth surface compared to metal shell, the outer surface of ceramic shell is relatively more uneven, thereby make cooling surface area relatively large, but there is a worse physical characteristic in ceramic material itself, be that its thermal conductivity factor is little, conduct heat slow, if ceramic heat-dissipating housing is thicker, the inner side of housing is long from outer side path, cause amount of heat to be accumulated in housing, more cannot from inner side, be transmitted to fast outside, and distribute from outside radiation, and, between substrate and housing, horizontal radial laminating contacts, in the situation that light fixture radial dimension is certain, radially contact area is limited for both, have influence on speed and the efficiency of heat propagation, the temperature of radiating shell itself is raise, also directly have influence on the normal operation of LED, cause LED excess Temperature, very easily lost efficacy or affected the use safety of light fixture.
Utility model content
It is high that the utility model takes full advantage of Thermal Conductivity by Using, and the thermal conductivity factor of the fast characteristic of conducting heat and pottery is low, but heat emissivity coefficient is high, that is to say that heat transfer is poor, the characteristic of rapid heat dissipation.Object is to provide a kind of LED light fixture of radiating structure, comprise plastic stent, ceramic heat-dissipating housing and the LED light source module group being formed by substrate and LED lamp pearl, it is characterized in that: be also provided with metal connecting piece, described metal connecting piece is provided with horizontal sides and bending edges, described horizontal sides is close to and is contacted with substrate level, and described bending edges stretches to be close to the sidewall of ceramic heat-dissipating housing and contacts.Particularly, this programme is by having set up a heat catalysis metal connecting piece, make substrate needn't directly fit and contact with ceramic heat-dissipating housing, do not affect again hot conduction, the heat producing on LED lamp pearl is passed to after substrate, by substrate, conducted to metal connecting piece again, because Thermal Conductivity by Using is high, the heat of LED lamp can be transmitted on ceramic heat-dissipating housing by metal connecting piece very soon, make when keeping substrate to contact with the laminating of LED lamp pearl horizontal direction, needn't require again ceramic heat-dissipating housing also to contact with substrate horizontal abutment, and, because the bending edges of metal connecting piece contacts with the laminating of ceramic heat-dissipating housing but not the horizontal plane of prior art radially contacts along the side wall surface of ceramic heat-dissipating housing, so the in the situation that of light fixture comparable size, the contact area of the contact area rate prior art of itself and ceramic heat-dissipating housing is much bigger, thereby also greatly increase heat conduction efficiency between the two.
Further, because the bending edges of metal connecting piece can change with the sidewall shape of ceramic heat-dissipating housing, also make the shape design space of ceramic heat-dissipating housing greatly liberate, rather than as prior art, for keeping the outline of ceramic heat-dissipating housing, have to change the inner side of ceramic heat-dissipating housing, by extension, thicken sidewall and yield to the requirement with substrate horizontal abutment, so ceramic heat-dissipating thickness of shell meet to be used under safe prerequisite greatly attenuate, in cross section, outside is parallel, consistency of thickness, be thin cylinder horn-like, this had both reduced material and processing cost, also make the heat that on substrate, conduction is come more easily from the inner side of ceramic heat-dissipating housing, thoroughly be dissipated to outside, finally be radiated in atmosphere, greatly shorten the heat dissipation path of ceramic heat-dissipating housing.
Further scheme is, described metal connecting piece is connected with described plastic stent locking by screw.Uncovered lower large little when ceramic heat-dissipating housing, described bending edges during along ceramic heat-dissipating housing from the relative upward sliding in uncovered bottom, will force bending edges plastic deformation, produce and support tension force, so its with ceramic heat-dissipating housing between to contact also will be tightr.So not only can lock the tautness of metal connecting piece and plastic stent, the dynamics that also can regulate bending edges and ceramic heat-dissipating housing to be close to by holding the dynamics of screw lock.
Further scheme is, on the contact-making surface of described bending edges and described ceramic heat-dissipating housing, is laid with thermal grease conduction, and the thermal grease conduction that possesses high thermal conductivity can further be strengthened heat conducting efficiency between the two.
By such scheme, simple in structure, save manufacturing cost, good heat dissipation effect, can be extended the service life of LED, and cost performance is high.Onesize light fixture, adopts the technical program, and than conventional ceramic LED lamp tool, power promotes greatly.
