'' A packaging structure for packaging a light-emitting diode with a substrate and two electrodes, the packaging structure includes an insulating carrier, and a through-hole is formed, the through-hole has a lower upper opening and is connected to the lower opening At least one stepped portion from the upper opening, the at least one stepped portion has a lower side wall surface connected to the lower opening, an intermediate table surface, and an upper side wall surface connected to the upper opening, wherein the substrate faces the Open down Π, and the depth of the through hole is sufficient to fully accommodate the light-emitting diode; ^ at least one planar metal layer is formed on the intermediate mesa and the upper side wall surface of the at least one stepped portion, · Page 27 582122-^^ 92ΐ〇Πβ 3, March 6th, the scope of the patent application for at least one area i other than the metal through-hole, formed in the surface of the insulating bearing seat on the at least one wiring [^: and connected to The at least one planar metal layer; a portion of the intermediate mesa = connected to the resin in the at least one planar metal layer and filled = one of 7 electrodes; and at least one wiring. ^ Beitong holes are used to seal the light-emitting diode and the 38. If the patent application Fanyuan seat is made of glass, ceramic, Ain packaging structure, where the insulating carrier plate, and a, plastic, resin, Or formed by printing e. 39. For example, the base of the scope of the patent application is formed by using an outer cavity of an insulating material and a packaging structure material, wherein the insulating carrier is covered with a metal core. 40. The package structure with a depth of less than 10 mm as in the scope of the patent application, 41, of which 41 of the through hole. The seal structure with the scope of the 37th aspect of the patent application. , Where the through-hole system is in the region of the force center. 42. It is formed by the epoxy resin under item 37 of the scope of patent application. And packaging structure, in which the resin is made of Ref. 43. For example, the packaging structure in item 37 of the patent application scope, in which the resin is added on page 28 582122 Add a material with high thermal conductivity to increase the heat dissipation of the package structure 44. If the application for a patent is based on the packaging structure of item 37 at the interface between the light-emitting diode and the high refractive index matching medium, the packaging structure is formed by a part of the material between the lower openings, reflection. 'Wherein the resin's median & has a package structure for reducing the substrate and the tree 45, such as the 37th in the scope of patent application, wherein a portion of the resin between the upper opening and the light emitting diode is added There is a highly reflective material to reflect the light generated by the light emitting diode. 46. If the package structure of the scope of patent application No. 37, further includes a reflective layer, coated on the resin, to reflect the light generated by the light-emitting diode 0 47. If the package of scope of the patent application No. 37 The structure further includes a refractive lens disposed at the lower opening of the through hole. 4 8. The package structure according to item 37 of the scope of patent application, further comprising a fluorescent layer 'coated on the lower opening of the through hole to provide light with a desired color. 4 9 · The package structure according to item 37 of the scope of patent application, wherein the resin is in the middle position Page 29 582122 ^ S_92101763 Scope of patent application --------- In this light-emitting diode, $ ^ --- Zou Miao between Xun Xiao and the reading opening will provide a mixed color with the desired color—fluorescent material 50. Such as the cover of the 37th patent application #hibi, The raw Gansu chain structure, wherein the material type of the light emitting diode calendar is aluminum gallium indium phosphide type, aluminum gallium indium nitride type, indium gallium nitride type, aluminum gallium arsenide type, silicon carbide type, or the like.
