Abstract
The utility model relates to an electronic circuit and shell body integration light emitting diode (LED) lamp. The electronic circuit and shell body integration LED lamp comprises a lamp shell and LED beads. An insulation and heat conduction layer is arranged on the lamp shell and the surface of the insulation and heat conduction layer is provided with an electronic circuit. The LED beads are welded on the electronic circuit. Through the structure, the electronic circuit and the lamp shell are seamlessly connected into a whole, so that the LED beads are welded on the lamp shell directly, an installation interface does not exist and an installation interface gap does not exist either. Consequently, the problem that thermal resistance of a gap interface of the installation interface is large enough to cause the service life of an LED lamp to be shortened is solved.
Description
Technical field
The utility model relates to lighting apparatus, a kind of LED light fixture of saying so exactly, and this light fixture is made as electronic circuit and housing integrated, the service life of having improved the LED light fixture.
Background technology
At present, the structure of the known high-power LED lamp of LED lighting manufacturing all is as shown in Figure 1.Wherein, lamp housing 1 ' is made respectively with led light source, through screw 3 ' or fastener etc. led light source (comprising: LED lamp pearl 2 ' and circuit board 4) is installed on the lamp housing 1 ' then.The lamp housing of LED light fixture is the radiator of LED light fixture in most cases in the LED light fixture, is responsible for the heat that led light source conducts out is dispersed in the air to reduce the temperature of led light source, guarantees LED light fixture service life.
The lamp housing 1 ' and the led light source of LED lighting all are to make respectively; In follow-up process according to combination; Because the installed surface flatness of lamp housing 1 ' (radiator) is limited; The contact-making surface flatness of led light source and lamp housing 1 ' also is limited, makes the slit 5 ' that has formed installation interface between led light source and the lamp housing 1 ' (radiator), and this slit 5 ' relative heat transfer theory requires the thermal resistance of generation excessive; Cause led light source when work to produce heat and can't be transmitted to lamp housing 1 ' (radiator) smoothly and distribute, and then cause reduce the service life of LED light fixture.In order to address this problem, the way that industry engineer uses always is between led light source and lamp housing 1 ', to coat heat radiation fat so that interface gaps 5 ' is filled, and reduces interface resistance.But heat radiation fat is dry easily the inefficacy under the effect of heat, still the problems referred to above can occur, also can influence the service life of LED light fixture.
Summary of the invention
Based on this, in order to overcome in the present LED fitting structure, the installation interface slit that led light source and lamp housing (radiator) form makes interface resistance excessive, and causes the problem of LED light fixture reduction in service life.The primary and foremost purpose of the utility model provides a kind of electronic circuit and the incorporate LED light fixture of housing; There is not installation interface in this LED light fixture; Just there is not the installation interface slit yet, thereby solved the excessive and problem that causes the LED light fixture to reduce service life of installation interface slit interface resistance.
Another purpose of the utility model provides a kind of electronic circuit and the incorporate LED light fixture of housing; This LED fitting structure is simple, reliable, has simplified the structure of LED light fixture, has reduced generation and installation procedure; Reduced cost of manufacture, can be widely used in the existing LED light fixture.
In order to achieve the above object, the utility model is to realize like this.
The incorporate LED light fixture of a kind of electronic circuit and housing, it includes lamp housing, LED lamp pearl, it is characterized in that said lamp housing is provided with the insulating heat-conductive layer, has electronic circuit on the surface of said insulating heat-conductive layer, and the bead weld of LED lamp is connected on the said electronic circuit.Through this structure; Make electronic circuit and lamp housing become an integral body of seamless link; Thereby LED lamp pearl can directly be welded on the lamp housing; There is not installation interface, just do not have the installation interface slit yet, thereby solved the excessive and problem that causes the LED light fixture to reduce service life of installation interface slit interface resistance.
Said lamp housing, its position that insulating heat-conductive layer is set is a burnishing surface, so that heat radiation is convenient in the even laying of insulating heat-conductive layer.
Said insulating heat-conductive layer is arranged in the lamp housing, to avoid external force LED lamp pearl is caused damage.
Said insulating heat-conductive layer is preferably resin Ceramic Composite glued membrane, plexiglas cloth (PP), pure resin glued membrane heat conductive silica gel, silica gel, the formed heat-conducting layer of any one of bond plies.
Said lamp housing has wavy outer surface at its back side that insulating heat-conductive layer position is set, and to increase area of dissipation, is convenient to distributing fast of heat.
The beneficial effect of the utility model is: 1, do not have installation interface, also just do not have the installation interface slit, thereby solved the excessive and problem that causes the LED light fixture to reduce service life of installation interface slit interface resistance.2, simplify the structure and reduced operation and reduced cost.
And this LED fitting structure is simple, reliable, has simplified the structure of LED light fixture, has reduced generation and installation procedure, has reduced cost of manufacture.
Description of drawings
Fig. 1 is the prior art constructions sketch map.
The structural representation that Fig. 2 implements for the utility model.
The specific embodiment
Below, shown in accompanying drawing, the practical implementation of the utility model is elaborated.
Shown in Figure 2, a kind of electronic circuit and the incorporate LED light fixture of housing that the utility model is realized, this light fixture includes lamp housing 1, LED lamp pearl 2, electronic circuit 3 and insulating heat-conductive layer 4.Wherein, the set inside of lamp housing 1 has insulating heat-conductive layer 4, and electronic circuit 3 is set on the surface of insulating heat-conductive layer 4 again, and LED lamp pearl 2 is welded on the electronic circuit 3.
The concrete preparation method of this LED light fixture shell is following.
The heat dispersion index that 1, will reach according to follow-up lamp housing and the needs of outer shape; The thickness of the metallic plate of selection manufacturing lamp housing 1 is with metal species; (insulating heat-conductive layer 4 preferably adopts insulating heat-conductive glue to the last insulating heat-conductive layer 4 of preparation above that then; Fixing to reach smoothly, and can guarantee that it is seamless with being connected of shell).
2, on insulating heat-conductive layer 4, be covered with the Copper Foil of desired thickness, then Copper Foil prepared electronic circuit 3 through the printed wiring board manufacturing process.
3, the metallic plate of preceding two steps being prepared that contains electronic circuit, the heat dispersion index and the outer shape of the LED light fixture of the follow-up manufacturing of foundation need mfg. moulding die, and lamp housing 1 is just processed in compression moulding.
4, just process through above three step lamp housings 1.The follow-up process LED lamp pearl 2 of on the electronic circuit 3 of lamp housing, burn-oning is mixed operations such as power supply and just processes the LED light fixture.
LED light fixture through the utility model is realized does not have installation interface, and the slit is not installed, and can not produce the excessive problem of slit interface resistance, thereby improves the service life of LED light fixture.
