Compared with prior art, one of beneficial effect of the utility model is: replace with heat conductivility pottery preferably through the heat-radiating substrate material with the LED light fixture, matching with the alloy bracket body encapsulates; Make the integral heat sink performance of led support obviously improve; Therefore a plurality of electrode interfaces can be set on heat-radiating substrate, be used for solid weldering plurality of LEDs chip, make the LED light fixture after the encapsulation under equal volume, obviously improve logical light rate; A plurality of electrode interfaces are parallel with one another simultaneously; Make wherein one or more electrode interfaces Shi Buhui that breaks down influence the normal use of other electrode interfaces, and a kind of integrated encapsulated LED supporting structure that the utility model provided is simple, volume is less; Be suitable for suitability for industrialized production, be easy to promote.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Embodiment

Below in conjunction with accompanying drawing the utility model is done further to set forth.

Embodiment:

A kind of integrated encapsulated LED support that the utility model provided; Comprise rack body 1 and be installed in the substrate on the rack body 1; Described substrate is a ceramic substrate 2; Its top is provided with a plurality of be used to install led chip, and electrode interfaces 3 parallel with one another, and each electrode interface 3 is all drawn through lead and extended to beyond the rack body 1, and also is provided with fixture on the rack body 1.The conduct of aforementioned fixation device is used on the shell or battery lead plate that rack body are fixed on the LED light fixture; The inventor of the utility model is with reference to prior art; Think here as fixture location hole 5 preferably, can conveniently adopt bolt or screw to fix, in addition; Fixture also can adopt other form, for example clamp button of the spring etc.

Referring to shown in Figure 1; Preferred as the utility model; The rack body of being mentioned in the technique scheme 1 preferentially is set to rectangle, and for the rack body 1 with rectangle is complementary, the heat radiation ceramic substrate 2 that is installed on the rack body 1 also is set to rectangle; Further say; The purpose that ceramic substrate 2 is set to rectangle is can be the netted a plurality of electrode interfaces that are used to install led chip that distribute that are provided with on it in order to make, and avoids the space waste on the ceramic substrate 2, and the lead that also helps on the electrode interface 3 is drawn.

Content to above-mentioned also need to prove; Above-mentioned technical scheme only is the preferred of the utility model, and the inventor finds in experiment, can aforementioned rack body of mentioning 1 and heat radiation ceramic substrate 2 be set to circle, ellipse even triangle; Even can also rack body 1 be set to circle; The ceramic substrate 2 that will dispel the heat is set to rectangle, and combination like that is even if compare with above-mentioned rectangle heat-radiating substrate; After the later stage is provided with a plurality of electrode interfaces 3, can cause too much space waste, but one of technical purpose and effect of the utility model remain and can realize at least.

Said according to as above, on the heat radiation ceramic substrate 2 of rectangle a plurality of electrode interfaces 3 can be set, but also need keep the gap between each electrode interface 3, prevent that led chip from influencing each other when luminous work.As preferably; Clearance distance between the electrode interface 3 can be selected in the middle of 3 to 5 millimeters, and the gap between the electrode interface 3 is remained on the width of aforementioned range, be appreciated that into the area of the ceramic substrate on the rack body 12 big more; The electrode interface 3 that can be provided with is just many more; Can the mounted LEDs chip also many more, and according to the different capacity of led chip, can adjustment arbitrarily in aforesaid scope; For example power is that the led chip clearance distance of 0.5W is set to 5 millimeters, and the led chip clearance distance of power 0.3W is set to 3 millimeters.

And the arrangement mode of electrode interface 3 comparative optimizations is for being netted arrangement; Specifically; For electrode interface 3 being set to cross one another formation shape; Intersection can also can be set to shown in Figure 1 a plurality of electrode interfaces 3 are lined up the row shape for intersecting at any angle, and orthogonal cross-distribution.

Simultaneously according to above-mentioned content; A plurality of netted arrangements and electrode interface parallel with one another 3 are set on heat-radiating substrate needs to adopt many leads to extend out; And get muddled after lead from extending to outside the rack body 1 for preventing; Cellular through wires hole 4 can also be set on rack body 1, electrode interface 3 extended leads are passed from through wires hole 4, the concrete form of through wires hole 4 is as shown in Figure 1; For the position of through wires hole 4, preferably it is arranged near the edge of rack body 1 corner near rectangle.

And according to the structure of above-mentioned said led support, in the middle of the heat dispersion of the rack body 1 mentioned need to echo mutually with heat radiation ceramic substrate 2, therefore in its material volume selection, preferentially adopt aluminium nitride or high heat conductive insulating resin aluminium to be processed into.

One of utility model point of the utility model is; On above-mentioned heat radiation ceramic substrate, weld a plurality of led chips admittedly; Make it to have obtained higher luminous flux in the relatively little volume, simultaneously on the basis of adopting a plurality of led chips to work simultaneously, avoided taking place because of wherein one or more led chips situation that the circuit that causes whole ceramic substrate can not connect that breaks down; Can need to use in the high light place at some, for example stage projector etc.

In addition; " embodiment ", " another embodiment ", " embodiment " that are in this manual to be spoken of that also need describe, etc., refer to the concrete characteristic, structure or the characteristics that combine this embodiment to describe and be included among at least one embodiment that the application's generality describes.A plurality of local appearance statement of the same race is not necessarily to refer to same embodiment in specification.Further, when describing a concrete characteristic, structure or characteristics in conjunction with arbitrary embodiment, what institute will advocate is that other embodiment of combination realize that this characteristic, structure or characteristics also drop in the scope of the utility model.

Although a plurality of explanatory embodiment with reference to the utility model is described the utility model here; But; Should be appreciated that; Those skilled in the art can design a lot of other modification and execution modes, and these are revised and execution mode will drop within disclosed principle scope of the application and the spirit.More particularly, in the scope of, accompanying drawing open and claim, can carry out multiple modification and improvement to the building block and/or the layout of subject combination layout in the application.Except modification that building block and/or layout are carried out with improve, to those skilled in the art, other purposes also will be tangible.
