Description
Technical field
The utility model relates to a kind of lighting, refers in particular to the conductive structure of led light source.
Background technology
LED (light emitting diode) technology starts from late 1960s; Through semicentennial developing rapidly, led light source, particularly high bright led light source;, volume little, long service life high with its light efficiency; And many-sided advantage such as environmental protection and energy saving, occupied critical positions in the lighting source field, and still in continuing to develop rapidly.
But along with the raising that LED uses intensity, the light efficiency of light source and the direct heating problem that influences led light source service life and luminous flux become the hot issue of common concern in the industry, and this problem has become the key factor of restriction led light source development.For handling led light source heating problem in use well; Various heat dissipating methods in led light source, have been used at present; Wherein natural cooling, good heat dissipation effect low, simple in structure, easy to use with its cost, advantage such as applied widely are preferentially selected for use by More and more factories.Natural cooling is to utilize hot transfer principle, and the utilization heat-conducting piece conducts the heat that circuit board produced and is diffused in the air, to reach the purpose to the circuit board radiating and cooling.Though use this method can realize heat radiation to the led light source circuit board.But when practical application, thinner because of board substrate on the one hand, toughness is bigger; Use the screw extruding that is provided with separately during installation, the circuit board segment that is between screw is prone to arch camber, warpage, thereby causes the contact area of circuit board bottom surface and heat-conducting piece to reduce; Influenced heat transference efficiency; Be prone to cause the circuit board temperature too high and produce aging or burn, reduced the service life of led light source, have the defective that heat transference efficiency is low, service life is short; On the other hand for circuit board bottom surface is fitted to increase heat transference efficiency with heat-conducting piece as much as possible; Then be used to connect and the screw number of compacting circuit board just is tending towards The more the better, on circuit board, just need process abundant connecting hole like this, correspondingly also need process the connection screw of respective numbers on the heat-conducting piece; Processing to quantity like this hole in the production not only will take too much consumptive material; And want the manual work of labor, and seem very uneconomical, obviously there is the defective of unreasonable structure.
The utility model content
Not enough to prior art, the utility model technical problem to be solved provides high, the rational in infrastructure led light source conductive structure of a kind of heat transference efficiency.
For solving the problems of the technologies described above; The led light source conductive structure of the utility model; Comprise lamp socket, on lamp socket, linking to each other is connected to circuit board, LED lamp pearl is fixedly set on the circuit board, is provided with locating slot on the said lamp socket symmetrically; On this locating slot notch outside inwall protruding flanging is being set, said circuit-board card inserts in the locating slot notch.
After adopting said structure; Because locating slot is being set on lamp socket symmetrically; Then can the direct card of circuit board be inserted in this locating slot, and use the protruding flanging that is being provided with on this locating slot notch outside inwall, make flanging produce plastic deformation through external force; Can realize circuit board is applied certain monolithic extruded power, make the flanging place circuit board bottom surface lamp socket of fitting fully.The low defective of existing heat transference efficiency when so not only having avoided original utilization that the screw mounting circuit boards is set separately; And saved original to the processing of installing hole and the utilization of screw.Has the heat transference efficiency height, advantage rational in infrastructure, as to use economy.
A kind of preferred implementation of the utility model is to be provided with heat-conducting layer between said circuit board and the lamp socket.This heat-conducting layer can effectively fill between circuit board and heat-conducting layer, and the gap that possibly exist between heat-conducting layer and lamp socket, thereby has more effectively guaranteed the complete applying between circuit board and lamp socket, has the heat transference efficiency height, advantage rational in infrastructure.
Description of drawings
Be described further below in conjunction with accompanying drawing and the specific embodiment led light source conductive structure the utility model.
Fig. 1 is the work structuring sketch map of a kind of specific embodiment of led light source conductive structure of the utility model.
Among the figure, 1-LED lamp pearl, 2-lamp socket, 3-heat-conducting layer, 4-circuit board, 5-flanging, 6-locating slot.
The specific embodiment
In diagram led light source conductive structure; Be provided with on it on lamp socket 2 of locating slot 6 symmetrically and connecting circuit board 4 through heat-conducting layer 3; On circuit board 4, welding many LED lamp pearls 1 that link to each other with circuit board 4 circuit, on the inwall of locating slot 6 notches outside, protruding flanging 5 is being set.Through this locating slot 6; Can circuit board 4 be inserted on the lamp socket 2 along its notch card; And make flanging 5 produce plastic deformations through external force, and can realize circuit board 4 is applied certain monolithic extruded power, make flanging 5 place's circuit boards 4 bottom surfaces lamp socket 2 of fitting fully; The low defective of existing heat transference efficiency when so not only having avoided original utilization that screw mounting circuit boards 4 is set separately; And saved originally to the processing of installing hole and the utilization of screw, it is high to have obtained heat transference efficiency, usefulness rational in infrastructure, as to use economy.Said lamp socket 2 is a section bar, and the utilization section bar is made lamp socket 2, is convenient to realize producing in batches, has and enhances productivity, and reduces the advantage of production cost.Said heat-conducting layer 3 is the silicone grease composite.The silicone grease composite not only has good heat-conducting; And have certain elasticity, its with can effectively fill the gap that possibly exist therebetween after circuit board 4 and lamp socket 2 combine, guaranteed the complete applying of 2 of circuit board 4 and lamp sockets; It is high to have obtained heat transference efficiency, usefulness rational in infrastructure.Said circuit board 4 base materials are aluminium body plate shape sheet material, and this aluminium body plate shape plate surface is shaped on circuit.Use aluminium body plate shape sheet material operation board substrate, have the advantage of good heat conductivity.
During production; The silicone grease composite is coated in lamp socket 2 locating slots, 6 baseplanes and flanging 5 lower surfaces; The circuit board 4 that will have LED lamp 1 pearl again inserts in the locating slot 6, makes it to produce plastic deformation through the flanging 5 on hydraulic pressure or the punching press both sides section bar, directly compresses circuit board 4.
Above-mentioned some preferred implementations of only enumerating the utility model led light source conductive structure, but be not limited to this, under the situation of the utility model basic principle, also can do some conversion and improvement.For example, the selected version of lamp socket differed is decided to be section bar, also can be self-making structure, and so on.The utility model is not only applicable to the LED lamp, and is applicable in other lighting.So long as the change of any analog structure of on the utility model basis, being done, all be regarded as falling into the protection domain of the utility model.
