Description
Technical field
The present invention relates to other transparent flexible materials such as a kind of LED flip-chip and plastics or organosilicon and be packaged into folding type LED light-emitting component as support.
Background technology
LED (Lighting emitting diode) is a kind of light-emitting diode, is the solid-state semiconductor device that is visible ray by electric energy conversion, is the green light source of a kind of high energy-conservation, high life, high light efficiency, environmental protection.
The support that at present LED Packaging Industry is used be all by harder material as package support, due to luminescence chip and support self character, even if transparent rack, namely the luminous illumination of support upper and lower surface is strong, the luminous intensities at other four sides a little less than; Affected the illuminating effect of LED.
In addition, Packaging Industry is all to utilize gold thread that common luminescence chip and support circuitry are coupled together at present, and such design is complex process not only, has also increased the cost of LED light-emitting component.
Summary of the invention
The object of the invention is to solve the deficiency of above-mentioned background technology, a kind of improvement of LED light-emitting component be provided, this LED light-emitting component should six luminous, and have technique simple, process convenient lower-cost feature.
Technical scheme provided by the invention is: folding type LED light-emitting component, comprises LED flip-chip; It is characterized in that described LED light-emitting component also comprises the support that surface is manufactured with circuit and makes of transparent flexible material, electric of described LED flip-chip connects material by conduction and is fixed on the surface of aforementioned brackets and is electrically connected to aforementioned circuit, separately by fluorescent glue, the back side of the positive of LED flip-chip and the corresponding support of this chip is together coated.
Described circuit is 1 series connection 1 parallel connection or 1 series connection 1 above circuit in parallel.
The material of described circuit is silver coating or Gold plated Layer or aluminium coated or nickel coating.
The width of described support is more than 0.5mm.
The width of described support is 2-5mm.
Described transparent flexible material is plastic sheet or silica gel piece.
Fluorescent material in described fluorescent glue is at least one in yellow fluorescent powder or red fluorescence powder or green emitting phosphor or blue colour fluorescent powder or purple fluorescence powder.
The invention has the beneficial effects as follows: owing to having adopted LED flip-chip and the support that is coated with circuit and makes of transparent flexible material with matching, not only save original gold thread and connected operation, significantly simplified production technology, and the LED light-emitting component forming can curve any shape as required, and then accomplished six faces, 360 degree uniformly light-emittings completely, and then illumination and the illuminating effect of LED have been increased substantially.
Accompanying drawing explanation
Fig. 1 is the structural representation of folding type LED light-emitting component of the present invention.
Fig. 2 is the A portion structure for amplifying schematic diagram in Fig. 1.
Embodiment
In figure: 1 is support, 2 is circuit, 3 conduction tie points, and 4 is LED flip-chip, 5 is fluorescent glue.
As described in Figure: the timbering material of folding type LED light-emitting component, adopt the material (thickness is preferably 2-5mm conventionally) of plastic sheet (such as polyethylene, polypropylene, nylon etc.) or silica gel piece or other transparent flexible materials, so just can make the LED light-emitting component forming be bent into needed any shape, thereby reach the effect that six faces can uniformly light-emitting.
For realizing and being electrically connected to of LED flip-chip 4, the surface of described support 1 is manufactured with circuit 2, and this circuit can adopt silver coating or Gold plated Layer or aluminium coated or nickel coating or other metal levels; On circuit, be also manufactured with conduction tie point 3(that the external positive and negative power supply of conducting uses as shown in Figure 2: the anodal pin 4-2 of each LED flip-chip and negative pole pin 4-1 are all welded on circuit and are isolated by the different branch on circuit).Described circuit can design (conventionally can adopt printed circuit) as required, recommends to be designed to 1 series connection 1 parallel connection or 1 series connection 1 above circuit in parallel.
