Description

A kind of LED light fixture radiator

Technical field

The utility model relates to a kind of LED light fixture radiator, and it belongs to LED light source body class.

Background technology

LED lighting is the novel energy-conserving light source body that development in recent years is got up, progressively replacing at present traditional lighting source body, in LED lighting, wherein LED bulb lamp is owing to having the compatibility of height with the face shaping of traditional incandescent lamp and matched lamp, be subject to very much liking of user for this reason, have very high occupation rate of market.Described LED bulb lamp generally comprises printing opacity ball bubble-cap, radiator, LED light source plate, is built-in with the body of driving power, described LED light source plate is arranged in radiator, described printing opacity ball bubble-cap and radiator lower end connect firmly and connect, and described body and radiator upper end connect firmly and connect.The initial period that LED bulb lamp occurs, described radiator generally adopts pack alloy structure, cost is higher, in recent years, in order to reduce costs, the fin that the radiator of LED light fixture adopts sheet metal to make more is stacked assembled, such LED light fixture hot body adopts fin stacked assembled, for this reason its structurally with the radiator LED light fixture difference to some extent that is pack alloy, the stacked assembled LED light fixture radiator of typical employing fin is that utility model patent CN201110078875.X is disclosed, it comprises: radiator, described radiator comprises the multiple fin that are radial arrangement around the central axis of described radiator, described in each, fin comprises the inward flange near described central axis, away from described central axis and the outward flange relative with described inward flange and connect described inward flange and described outward flange and top edge respect to one another and lower limb, described radiator is further provided with the first cavity extending along described central axis, lower cover, described lower cover is supported on described lower limb, and is provided with first through hole corresponding with described the first cavity, fixed head, described fixed head is supported on described top edge, and is provided with second through hole corresponding with described the first cavity, connector, is arranged in described the first through hole, described the first cavity and described the second through hole, and clamp described lower cover relative with described fixed head away from both sides, so that described lower cover and described fixed head are fixed on described radiator.

In the disclosed structure of CN201110078875.X, described upper cover, lower cover also plays a part in essence to circumferentially location of fin, concrete structure is upper cover, lower cover is formed with end face slot in the face of on the end face of fin, described end face slot respectively with top edge and the lower limb of fin, when combination, top edge and lower limb are plugged in respectively in the end face slot of upper cover and lower cover, by the circumferential position of the fixing each fin of such mode, to make the definite and stable mode of appearance that has of radiator, the problem that the disclosed this LED light fixture radiator of CN201110078875.X exists mainly contains two aspects, the one, the circumferential locate mode of fin, that top edge by fin or lower limb plug in the end face slot of upper cover or lower cover and realize, such structure is no problem for thicker fin, but for relatively thin fin, upper cover or under cover the end face slot size corresponding with thinner fin formation also can only be less, this may go in theory, but realize production in, be limited to equipment, upper cover, the impact of the factors such as lower cover material therefor, the end face slot size forming is restricted in essence, like this, adopting in the situation that thinner metal material makes with regard to having caused such circumferential positioning structure to be difficult to the less and fin of some dimensions like this, the problem of another aspect is the axial connection of cooling fin device, upper cover, three main components of lower cover, it is to realize by a special connector, in the time of assembling, whole technique comprises insertion, the punch riveting etc. of connector, in the uncertain situation of upper cover radiator axial location relative to lower cover, carry out such connection, usually easily there is waste product, in sum, obviously prior art has further improved necessity.

Summary of the invention

The purpose of this utility model is to provide a kind of LED light fixture radiator, the problem existing to overcome prior art.

A kind of LED light fixture radiator of the present utility model, comprise radiator, described radiator comprises the multiple fin that are radial arrangement around the central axis of described radiator, described in each, fin comprises the inward flange near described central axis, away from the outward flange of described central axis, and connect described inward flange and described outward flange and top edge respect to one another and lower limb, described top edge and the upper hem and the lower hem that on lower limb, at least form respectively a relative fin base plate, described radiator at least comprises an interior cavity being limited by described inward flange, also comprise upper cover and lower cover, it is characterized in that upper cover and lower cover cover respectively in the lower heat conduction plane that the upper and lower flanging of upper connection plane that described upper hem limits limits, on the upper hem of described fin and lower hem, be formed with respectively location structure, described location structure comprise be formed on the locating hole in upper hem and/or lower hem plane or be formed on upper hem and/or the outer edge of lower hem on locating slot, described upper cover and/or lower cover are towards being formed with on the end face of radiator one side and tacking sheet or the locating dowel of aforementioned locating hole or locating slot adaptation, tacking sheet and/or locating dowel plug respectively vertically or are plugged in described locating hole and/or locating slot, described upper cover comprises respectively the upper central area He Xia central area corresponding with described interior cavity with lower cover, He Xia central area, upper central area is formed with riveted holes on one of them, on another, be formed with the connection riveting sheet corresponding with described riveted holes, described connection riveting sheet is located in vertically in described riveted holes and forms riveted joint by upper cover, radiator and lower cover are connected as one admittedly.

This LED light fixture radiator of the present utility model, by the change of circumferential positioning structure mode, the circumferential positioning structure application that has overcome prior art is subject to heat sink sizes size, particularly be subject to the problem of fin thickness limits, and the possibility that simultaneously realizes upper cover radiator axial location relative to lower cover location under the condition that realizes circumferential positioning function is provided; The utility model is by the improvement to prior art draw bail simultaneously, and prior art has reduced structure member relatively, makes assembly process more simple simultaneously, and in sum, obviously the purpose of this utility model is achieved.

As preferably, described lower cover is hardware, the tacking sheet covering under described and connect riveting sheet and all form by punching press, and as further preferably, described tacking sheet is through forming riveted joint after locating hole.The lower hem of fin defines the lower heat conduction plane of radiator in essence, the aluminium base of LED light source plate will conduct heat to radiator by this heat conduction plane, adopt this preferred structure, the lower heat conduction plane laminating that lower cover is direct and lower hem limits, and further strengthen the tightness degree of described laminating by riveted joint measure, while adopting like this utility model to form LED light fixture, the aluminium base of described LED light source body, as long as laminating is arranged under described to be covered, can guarantee that LED light source body is to the good heat-conductive characteristic that has between radiator.
