Abstract
The invention discloses a high-power LED (Light Emitting Diode) encapsulating bracket which comprises a base, wherein a positioning frame for forming an LED chip encapsulating region is fixed on the base and consists of a lower layer substrate and an upper layer insulating panel; the substrate is made of a printed circuit board; the surface of the substrate is provided with circuits for forming internal and external electrodes and connecting the internal and external electrodes; and the insulating panel covers a substrate surface except a region where the internal and the external electrodes are formed. The substrate and the insulating panel are convenient to manufacture, the size and the appearance of the encapsulating bracket can be adjusted as required without any special mold, high generality is achieved, and the manufacturing cost can be lowered. Moreover, a uniform-temperature plate can be taken as the base, so that high heat conducting capability is achieved.
Description
Technical field
The present invention relates to a kind of high-capacity LED package support.
Background technology
When LED industrial prospect a slice was good, high-power LED light source became the focus of everybody concern at present.Its encapsulation process roughly is divided into following a few step: Gu crystalline substance, bonding wire, dot fluorescent powder, covering.Therefore as the main element in the light source manufacturing process, package support plays crucial effects, and in order to guarantee carrying out smoothly of above-mentioned several procedures, it must possess following function: 1. the base as supporting role is arranged; 2. contain the functional areas that chip attach and welding position are provided; And there is certain indent degree of depth functional areas, and the interface that combines with glue is provided; 3. support integral body can be born the above high temperature of 150 degree at least; 4. can provide electric pathway smoothly, guarantee that light source is connected with circuit external; 5. thermoelectric the separation.The package support that generally uses in the market, base big more options copper base or ceramic base, with copper base package support is example, it comprises the silver-plated substrate in bottom, the location frame of being made by the PPA plastics, as the parts such as metal clips of electrode, substrate surface has several through holes, form location frame by through hole injection PPA material and at substrate surface with certain altitude and shape, as the metal clips of electrode by in the pre-buried location frame that is embedded in moulding.The package support advantage of this structure is that operability is good, and shortcoming is the package support complex manufacturing technology, and versatility is poor, and location size of frame and shape are subjected to the injection mold restriction and unadjustable.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art part, a kind of high-capacity LED package support is provided, have and make simply, the characteristics that the size of location frame and shape are easily regulated.
For achieving the above object, the present invention has adopted following technical scheme: it comprises base, be fixed with the location frame that is used for packaging LED chips on the base, the location frame is provided with the interior electrode that is electrically connected with led chip, the external electrode that is electrically connected with external circuit, described location frame is by laminar substrate and upper strata insulating panel are formed down, described substrate is made by printed circuit board, substrate surface has and is used for the circuit that forms inside and outside electrode and connect inside and outside electrode, and insulating panel covers and removes the substrate surface that forms inside and outside electrode zone.Substrate and insulating panel can be fixed on the base by bonding or gum or pressing mode, and substrate and insulating panel are easy to make, and its size and shape can be adjusted as required, do not need particular manufacturing craft, and versatility is good, can reduce manufacturing cost.
The base material of described substrate and insulating panel can be glass mat, or other substrate for printed circuit board.
Described base can adopt temperature-uniforming plate.Special capillary structure is contained in its inside, and the capacity of heat transmission is better than copper base and ceramic substrate greatly, and the temperature-uniforming plate moderate cost, does not increase product cost.
As shown from the above technical solution, substrate of the present invention and insulating panel can be fixed on the base by bonding or gum or pressing mode, and substrate and insulating panel are easy to make, its size and shape can be adjusted as required, do not need particular manufacturing craft, versatility is good, can reduce manufacturing cost.And can adopt temperature-uniforming plate as base, the capacity of heat transmission is good, with 100W integrated optical source is example, 4000h bad light under the normal temperature, continue to light the 1000h light decay below 2% under 45 ℃, 85%RH environment, and traditional copper substrate 100WLED integrated optical source before, the down aging 1000h light decay of normal temperature is about 10%.
