[embodiment]
Describe the present invention in detail below in conjunction with accompanying drawing and specific embodiment, illustrative examples wherein and explanation are only used for explaining the present invention, but not as a limitation of the invention.
As shown in Figure 1 and Figure 2, a kind of described in this embodiment can 360 degree of luminous LED planar package devices, it comprises transparent ceramic base 1, the position that described transparent ceramic base 1 surface is corresponding with outer, the back side, is respectively arranged with the inside groove 2 and microflute 3 that set gradually from inside to outside along circumferential direction surrounding; Be respectively arranged with some LED chips in inside groove 2 surrounding at described transparent ceramic base 1 surface and the back side, this LED chip can be connected by series and parallel connections by the gold thread 4 being arranged on inside groove 2; The LED chip of described inside groove 2 surrounding is filled out and is provided with inside groove phosphor powder layer; Fill out in described microflute 3 and be provided with microflute phosphor powder layer; Described transparent ceramic base 1 four jiaos of ends are provided with electrode 5, and this electrode 5 is connected with gold thread 4.
The inside groove 2 at described transparent ceramic base 1 surface and the back side is highly its LED chip thickness and inside groove phosphor powder layer height sum, and the surface of the inside groove phosphor powder layer at the surperficial and back side of this transparent ceramic base 1 is in same level with the surface of transparent ceramic base 1 or the back side respectively.
The groove depth of described microflute 3 is a bit larger tham inside groove 2.
LED chip in the inside groove 2 at described transparent ceramic base 1 surface and the back side adopts the positive and negative setting that is dislocatedly distributed; The luminescence making full use of LED chip front and side runs into fluorescent material and excites and change into efficient white light.
The present invention in use, LED chip is blue light or red LED chip, be provided with in inside groove on transparent ceramic base surface and the back side and be evenly provided with LED chip respectively, this LED chip is provided with inside groove phosphor powder layer, transparent ceramic base surface all can be connected by series and parallel connections by the gold thread set within it in groove with some LED chips at the back side, when starting working, LED chip utilizes to be possessed 360 degree of lighting functions and is excited into efficient white light by the inside groove phosphor powder layer that arranges on the inside groove at transparent ceramic base surface and the back side, but because ceramic substrate is transparent, therefore when 360 degree luminous, the light sent due to LED chip body is blue light or ruddiness, because light can reflect at medium, thus a blue light or ruddiness is still had to appear from transparent ceramic base surrounding sidewall, now due to outside inside groove and between transparent ceramic base outer, be provided with the microflute darker than the groove depth of inside groove, and fill out in microflute and establish full fluorescent material, through microflute after the light refraction that now band is blue or red, the fluorescent material be arranged in microflute absorbs, thus blue light or ruddiness are met fluorescent material and are excited into efficient white light and send, thus the efficient white light of 360 degree can be sent in transparent ceramic base.
The present invention makes full use of the light transmission features of transparent ceramic base, all evenly to be interspersed LED luminescence chip at the outer positive and negative inside groove of transparent ceramic base, LED chip itself possess 360 degree luminous, the efficient white light that the LED chip of surface light emitting and the LED chip of back side illuminated produce fully mixes and reaches 360 degree of uniformly light-emittings and light mixing effect.
In addition the present invention is under same power, the LED chip of reduced size can be adopted to be evenly distributed in inside groove, thus be decreased through the current density of LED chip, afterwards the extremely temperature of LED chip is reduced, and then can allow the more uniformly heat conduction and distributing of the Btu utilization transparent ceramic base that sends during chip operation, do not make heat build-up, extend the useful life of this product.
The present invention utilizes transparent ceramic height printing opacity, high thermal conduction characteristic makes planar package device substrate, the same device of the inside groove arranged by transparent ceramic base upper surface and microflute and its back side, LED chip operationally sends blueness or red light, run into transparent ceramic base surface, facade (side), the back side phosphor powder layer excite, send efficient white light; It is that one has structure simply, and planar package device technique is simple, and efficiency utilization LED chip 360 degree of characteristics of luminescences reach the LED planar package device device of 360 degree of luminescences.
It is the square of circular arc that the shape of transparent ceramic support of the present invention not only can be corner, also can rectangle or triangle or other shape.
Its employing corner of the present invention is in the transparent ceramic base of fillet, its tow sides are provided with inside groove and microflute successively from inside to outside along the surrounding corresponding position of circumferential direction, LED chip is provided with in this inside groove, this LED chip and microflute are provided with phosphor powder layer, it is simple that it has structure, send by the LED chip inside inside groove the fluorescent material that blue light or ruddiness runs into covering and be excited into efficient white light, microflute is provided with phosphor powder layer transparent ceramic base four sidewall overflow blue light out or ruddiness can be made to run into fluorescent material be excited into efficient white light, it can 360 degree luminous without dead angle, energy-conserving and environment-protective.
The above is only better embodiment of the present invention, therefore all equivalences done according to structure, feature and the principle described in patent claim of the present invention change or modify, and are included in patent claim of the present invention.
