Description
Technical field
This is novel, and what relate to is a kind of LED package support, and concrete is a kind of LED package support of all-metal construction.
Background technology
Current traditional LED package support is mainly that LED is granule sealed in cross section is the support of the reflective cup-shaped of inverted trapezoidal, plastics or pottery+metal electrode composition, and LED particle left and right has 2 electrode pins to extend outside support.This traditional scheme complex process and owing to using plastics on the one hand to cause reflector efficiency low for reflectorized material; Because sheathing material is plastics, its thermal conductivity is poor on the other hand, and heat radiation only depends on 2 electrode pins in left and right, so cause integral heat sink poor effect.So it is high to design a kind of reflector efficiency, the packaged type that heat conductivility is good is just very important.
Summary of the invention
In view of this, in order to address the above problem, to the invention provides one and improved for above-mentioned shortcoming, technique is simple, the Novel LED encapsulating bracket of the low reflective good heat dissipation effect of cost.
For achieving the above object, the present invention adopts following technical scheme:
A LED package support for all-metal construction, is characterized by and make the rack body with spill reflector with metallic plate;
Use high temperature insulation adhesive layer, the upper surface that two relatively independent sheet metals that separate is fixed on to described rack body forms an integrated all-metal LED package support with input and output electrode under insulation protection condition;
LED chip is fixed on to the upper surface of described spill reflector, described two sheet metals are near forming electrical connection between one end of LED chip and LED chip; Or can do the coating being electrically connected with described LED chip at the upper surface Direct precipitation of described spill reflector by physics or chemical method;
Further, with fluorescent material or silica gel or remote fluorescence film, the LED package support of described all-metal construction is carried out to packaging protection.
Further, described spill reflector cross sectional shape can be trapezoidal.
Further, the method for described fixed L ED chip can be that elargol, silver slurry are fixing.
The mode of the electrical connection further, forming between described one end near LED chip and LED chip can be to stamp spun gold or filamentary silver.
Further, described trapezoidal reflector upper surface is silver-plated or aluminize or adopt nanometer reflectorized material coating.
Further, the rete that described high temperature insulation adhesive layer can be epoxy resin, Parylene, PET or polyimides, esters of acrylic acid or structure glue-line, or the combination of above various materials, or the modification colloid mixing with highly heat-conductive material.
Further, there is Parylene coating on the surface of the LED package support of described all-metal construction encapsulation finished product.
Further, the lower surface heat dissipation metal substrate common and light fixture of described rack body welds, and described heat dissipation metal substrate surface can be electroplated with materials such as the silver of middle soldered, nickel, tin, chemical deposit processing allows its surface possess the weldability energy mutually general with SMT equipment.
Beneficial effect:
Adopt after this programme, LED chip can directly be encapsulated in high reflective, high heat conduction, metal cup body upper base surface face with optical design function.The metal electrode of this support not only has good reflective heat dispersion simultaneously, and is designed with good insulation protection between it and rack body.
The LED device encapsulating by this technology, while being applied to light fixture product, at the bottom of its solderability cup, between (being rack body reverse side) and the heat dissipation metal substrate of light fixture, available low temperature soldering technology forms good thermal dissipating path; The LED package support of all-metal construction proposed by the invention, compares with the LED package support that plastics and metal material and ceramic material are designed to traditional, can significantly promote light efficiency and the heat dispersion of LED packaging.
Brief description of the drawings
Fig. 1 is this novel side sectional view.
Embodiment
With reference to the LED package support of figure 1, a kind of all-metal construction, make the rack body 1 with spill reflector 11 with metallic plate; With high temperature insulation adhesive layer 2, the upper surface that two relatively independent sheet metals that separate 3 is fixed on to described rack body 1 forms an integrated all-metal LED package support with input and output electrode under insulation protection condition; LED chip 4 is fixed on to the upper surface of described spill reflector 11, described two sheet metals 3 are near forming electrical connection between one end of LED chip 4 and LED chip 4; Or can do the coating being electrically connected with described LED chip 4 at the upper surface Direct precipitation of described spill reflector 11 by physics or chemical method; The LED package support of described all-metal construction is carried out to packaging protection with the mixed silica gel of fluorescent material or remote fluorescence film.Described spill reflector 11 cross sectional shapes can be trapezoidal.The method of described fixed L ED chip 4 can be that elargol, silver slurry are fixing.The mode of the electrical connection forming between described one end near LED chip 4 and LED chip 4 can be to stamp spun gold or filamentary silver 5.Described trapezoidal reflector 11 upper surfaces are silver-plated or aluminize or adopt nanometer reflectorized material coating.The rete that described high temperature insulation adhesive layer 2 can be epoxy resin, Parylene, PET or polyimides, esters of acrylic acid or structure glue-line, or the combination of above various materials, or the modification colloid mixing with highly heat-conductive material.The surface treatment of the LED package support encapsulation finished product of described all-metal construction adopts Parylene technology.The lower surface heat dissipation metal substrate common and light fixture of described rack body 1 welds, and described heat dissipation metal substrate surface can be electroplated with materials such as the silver of middle soldered, nickel, tin, chemical deposit processing allows its surface possess the weldability energy mutually general with SMT equipment.
The technology that the thermoelectricity that the present invention adopts separates, compare with traditional scheme, difference is that the present invention adopts trapezoidal reflector 11 upper surfaces silver-plated or aluminize or adopt nanometer reflectorized material coating to form full mirror-reflection, and bright dipping reflection efficiency has improved more than 15% than traditional LED package support.Owing to adopting all-metal construction, and can directly be welded on heat dissipation metal substrate, arrive again traditional LED device application mode of heat dissipation metal substrate to Copper Foil to insulating barrier compared with electrode, the LED device that utilizes this package support to produce, its area of dissipation has had the expansion of tens times compared with traditional electrode, conventional plastic or ceramic light-reflecting cup are upwards reduced by electrode and the Copper Foil thermal diffusion adverse effect forming of dispelling the heat, reduce downwards one deck thermal resistance (packaging of the present invention can directly be welded on nonisulated heat sink on, and conventional package need to be dispelled the heat by the insulation processing of circuit or substrate, it will form together inevitably thermal resistance), its comprehensive heat dispersion will promote hundreds of times.And this scheme technique is simple, and cost is low, good reliability.
