Description
Technical field
The utility model relates to the LED lighting field, particularly relates to a kind of LED illuminating lamp with radiator structure.
Background technology
In existing LED lighting field, use great power LED as lighting source more.Even but great power LED compares with conventional light source such as sodium vapor lamp, Halogen lamp LED or fluorescent lamp, single led power is still on the low side relatively, so the LED illumination often adopts a plurality of LED to combine light source as a whole.For example be combined as the desk lamp lamp light source, be combined as the light source of tunnel illuminating lamp etc. with 48 great power LEDs with 7 great power LEDs.Many in this type of example these 7 or 48 great power LEDs are made on the substrate, are welded to connect fixing and as an integrated light source.The way that the direct soldering group of a plurality of great power LEDs of this usefulness synthesizes integrated light source, do integrated light source and light fixture together again considers to exist fairly obvious drawback from the heat radiation angle: the one, and existing heat dissipation design is to carry out at integrated light source, be not at single led design, normally a special particular heat spreader part at this integrated light source of being with in addition by lamp outer casing or light fixture dispels the heat, radiating efficiency is difficult to improve, and influences the service life of illuminating LED; The 2nd, different integrated light source designs, have different physical dimensions and luminous power, correspondingly, light fixture provided for the radiating element of the specific setting of integrated light source also just different, need do redesign for this reason and make, thereby cause radiating element is made and even light fixture is made poor efficiency and expensive.
The utility model content
For a change synthesize the above-mentioned drawback that integrated light source exposes with the direct soldering group of a plurality of great power LEDs on radiator structure, the utility model has carried out the improvement that divides merging to execute to the radiator structure of LED illuminating lamp.Its thinking is that the integrated light source of LED illumination is assemblied in by activity assembling connected mode by some led light sources unit on some light source interface of lamp socket end face and forms, each led light source unit is made up of a radiator unit and one or more great power LED integration one, makes each led light source unit that independently heat sinking function (this is radiator structure " branch ") all be arranged; Light source interface, lamp socket or lampholder cover in the light fixture also carries radiator structure simultaneously, led light source unit and light source interface, lamp socket and lampholder cover in the light fixture are gone here and there in regular turn and are adjacently carried out easily that heat radiation is connected, LED is dispelled the heat carry out (this is that radiator structure " closes ") on two aspects that led light source and light fixture combine.The technical solution of the utility model specifically is achieved in that
A kind of LED illuminating lamp with radiator structure, comprise that the integral illumination light source that one to multiple small cup led light source unit is formed reaches mainly by lampholder cover, lamp socket and led light source interface are in the structure of the supporting light fixture of interior composition, lampholder cover and lamp socket are connected and fixed, the lamp socket end face has some led light source interfaces of realizing circuit communication, each led light source interface can connect a led light source unit, it is characterized in that: every led light source unit is the individual components that is integrated by a radiator unit and one or more great power LED, the led light source interface, each parts of lamp socket and lampholder cover carry radiator structure.
As optimized technical scheme:
Aforesaid a kind of LED illuminating lamp with radiator structure, wherein, the radiator structure that carries of described led light source interface, lamp socket and lampholder cover comprises the structure of utilizing radiating fin to increase cooling surface area, or comprise hollow out, hole, window, the open type structure of fluting, skeleton shape or network structure.
Aforesaid a kind of LED illuminating lamp with radiator structure, wherein, the radiator structure that carries of described led light source interface, lamp socket and lampholder cover comprises that also the part that contacts with each other between the adjacent parts is to be made by heat-conductings such as aluminium, aluminium alloy, copper, copper alloy or stainless steels.
Aforesaid a kind of LED illuminating lamp with radiator structure, wherein, the radiator unit of described led light source unit is column construction and the through hole that has up/down perforation.
The beneficial effects of the utility model are:
1) make great power LED cooling more efficient:
Because one is become with radiator unit in the high-power LED light source unit, the most of heat that produces during each LED work not only spreads with heat exchange pattern by the radiating fin of corresponding radiator unit at any time, and to having carried out the design of secondary radiator structure with the matching used light fixture in led light source unit, lampholder cover, lamp socket, the adjacent in regular turn implementation with the led light source unit of the led light source interface of lamp socket end face is easily dispelled the heat and is connected, aluminium is adopted in its coupling part, the contour heat-conducting of copper, and employing comprises hollow out, boring, window, flutings etc. are in the interior open type structure that is easy to dispel the heat, thereby form from heat loss through convection, the heat that makes the led light source unit produce can continue heat radiation by the secondary radiator structure that light fixture provides, realized the heat radiation of two levels from the light source to the light fixture, therefore radiating efficiency significantly improves, and this is very useful to the service life that prolongs illumination LED.
2) make the work simplification of LED illuminating and heat radiating structure fabrication, cost reduces:
In the past with the synthetic integrated light source of the direct soldering group of a plurality of great power LEDs, when doing integrated light source and light fixture together again, in order to make integrated light source have good heat radiating, often to join a big stupid thick radiating element, from design, die sinking is to making of material, complex process, cost is considerable, in case and lighting source power or size change, redesign, die sinking are made again, cause the poor efficiency manufactured and expensive.In the utility model, radiator unit in the led light source unit is radiator structure independently, its design is irrelevant with light fixture, also irrelevant with integrated light source, only with relevant with its one or several great power LED of becoming one, the heat radiation object is therefore single relatively fixing, is easy to the design and the structure typing of radiator unit.On the other hand, by disperseing independently the led light source unit to bear respectively, this has also alleviated heat radiation load of light fixture part radiator structure to main heat sinking function.So, no matter be the radiator structure of led light source unit, or the radiator structure of light fixture relevant portion, its functional burdening, designing requirement, manufacture craft and production cost all can significantly reduce.
3) created condition for the large-scale production of lamp light source:
The led light source unit that uses in the utility model is the individual components that one or several great power LED and radiator unit are integrated one; change in the past with the synthetic integrated light source of the direct soldering group of a plurality of great power LEDs, again integrated light source and light fixture are done LED light structures together; thereby make the led light source parts realize modularization; the led light source parts can break away from light fixture to be made separately, thereby is convenient to the large-scale production of lamp light source.Consequent another benefit is installation and the maintenance that makes things convenient for lamp light source, and which led light source unit damages is only just changed which, can not involve other unspoiled led light source unit, thereby save cost.
