Description of the Invention: [Technical Field] The present invention relates to a white light emitting diode element and a method of fabricating the same, which utilizes ultraviolet light to excite a fluorescent material and generate a full-band visible light. And the formation of white light. [Prior Art] A light-emitting diode (LED) is a photovoltaic element that can emit light by itself after receiving an electric Φ force. It has a small size, excellent power efficiency, and excellent initial driving characteristics, and thus has been widely used. For general lighting 'large kanban and display backlights and other uses. At present, the types of light-emitting diodes can be classified according to the semiconductor materials they use, such as GaAs, GaAS1_xPx or GaP series. In addition, if a nitrogen atom is doped in the GaAS1_xPx or GaP series semiconductor materials, light of different colors can be generated. In general, the light emitted by the light-emitting diode has a monochromatic wavelength characteristic, and the length of the wavelength is determined according to the energy change during the sub-transfer process, and the wavelength actually used is 3 infrared. Light, red, green, yellow and blue. In human vision, the feeling of multiple colors can be produced by the sensing of two different colors of red, green and blue. This is also called the "three primary colors" of red, green and blue. • On the right, two different wavelengths of red, green and blue light source diodes are arranged adjacent to each other, and other colors of light can be obtained by mixing light. U.S. Patent No. 5,995, issued to U.S. Patent No. 5,995, the entire disclosure of which is incorporated herein by reference. The above-mentioned white light produced by mixing colors of light sources of different wavelengths has a hue and H:\HU\LGC\A34276\104 Π 〇\10411 〇d〇 (1310612 brightness dispersion problem, so it is not easy to produce the white light that is really needed. The white light source system is composed of different electrical diodes, and must be controlled by a suitable driving circuit, respectively. Therefore, the system design is complicated. In addition, U.S. Patent No. 6,614,179 discloses the generation of blue light by a light-emitting diode. ' s Xuan blue light will stimulate the sizing agent to produce yellow light. When the two light sources are mixed, white light is formed, wherein the blue light wavelength is 420nm~490nm, and the sizing agent is composed of {[(Y,Gd)Sm](AlGa)0 :Ce} is composed of. However, the white light produced by this method has a poor performance on the true color of the object, that is, the color temperature (c〇1〇r B temperature) is high and the color rendering property (c〇1〇r rendedng index) is not Therefore, in order to develop a high color rendering white light, it is necessary to control or adjust the proportion of the light contained in the light source to make it close to the composition ratio of natural light, so that the color of the object presented can be compared. lifelike In addition, in the development of fluorescent materials, the composition of yttrium aluminum garnet crystals (chemical formula: X3 (A3B2) 〇 12) is currently the focus of research and development, such as YAG phosphor structure • Y3 (Al3Al2) 〇12 , (Y3_xCex)Al5〇i2, (γ2 9Tb〇〇5)Al5〇i2, and (Y2.95-aCe0.05Gda)(Al5.bGab)O12, etc. Although a red phosphor can be mixed in it and promoted In the white light, the red color is injured, but it is excited by the blue light of the ultraviolet light, so the efficiency and heat stability are poor, that is, the durability is not good. In addition, for the wavelength region where the human eye actually feels the red component, It is so dark that it cannot have the same brightness as the green and blue areas. There is also a white light-emitting diode element that uses three or more kinds of phosphors emitted by the light-emitting diodes to excite three or more types of phosphors. Produce at least three kinds of H:\HLALGC\A34276\10411 〇\1 〇41 i〇, d〇c 1310612 wavelength light and mix to get white light. One of the prerequisites is to use a variety of phosphors to make work light at the same time. The selected excitation light can be absorbed by these glory bodies. 'And the absorption coefficient of light of this wavelength of each phosphor cannot be too different, so the difficulty of selecting the phosphor is greatly increased. On the other hand, the equation of this color is a nonlinear equation of more than two times, and it is to be allocated. The correct proportion of the three primary color phosphors has also become complicated. In summary, there is a need in the market for a white light emitting device that is similar in composition to natural light, and has better luminous efficiency and brightness. The object of the invention is to provide a white light-emitting diode element and a method of manufacturing the same, which utilizes a single fluorescent material to receive excitation of ultraviolet light generated by a light-emitting diode to generate a full-wavelength visible light fluorescent light to form white light. Another object of the present invention is to modify the phosphorescent material by an organic modifier to have an organic ruthenium group, whereby the organic functional group is combined with the mold member or the encapsulant, even in the mold member or package. During the hardening process of the rubber material, the organic functional group may generate a crosslinking reaction with the mold member or the encapsulating material, and the modified μ material may be uniformly dispersed in the mold member or the package kicking material to improve the production. Rate and adhesion. A further object of the present invention is to provide an ultraviolet light-blocking material which is mixed into an adhesive material between a light-emitting diode and a support carrier, so that the adhesive material is not easily deteriorated by ultraviolet light irradiation, which may cause adhesion. Poor sex and poor exposure of the light-emitting diode to the support carrier. In addition, the ultraviolet light intercepting material can be mixed into the mold member. The ultraviolet light absorbed by the fluorescent material does not leak to the ..., thereby causing damage to the human eye or other objects. H:\HU\LGC\A34276\104110\] 04110.d (1310612: for the above purpose, the present invention discloses a white light emitting diode element and a manufacturing method thereof, the light emitting diode element comprising - capable of generating ultraviolet light Light-emitting body and a fluorescent material.

The luminescent material can be added to organic materials. Modification, the original inorganic fluorescent material has an organic palace (4). In addition, an ultraviolet light blocking material may be included to prevent ultraviolet light from leaking into the environment and protect the organic glue present in the light emitting diode element. The material is irradiated and aged. The light-emitting diode of the light-emitting diode-nitride semiconductor series (A1 "χ yinxGayN") generates ultraviolet light having a wavelength between 33 〇 nm and 41 such as a claw, especially at a wavelength of 370 〜 The ultraviolet light of 380 nm is preferred.

The fluorescent material is an inorganic material and is not easily mixed with the organic rubber material, so that an organic substance can be added to be modified to have an organic functional group. The organic functional group may be cross-linked or mixed with the mold member or the encapsulant to achieve uniform dispersion in the mold member. The modified organic substance is a carbon-containing modifier, a dispersant, a catalyst and One of the surfactants or a combination thereof. Since ultraviolet light may deteriorate the mold member or the encapsulant of the organic material and cause harm to the human eye, the ultraviolet light that is not absorbed by the fluorescent material must be H:\ HU\LGC\A34276\104110\104110.doc _ 〇_ 1310612 Block it so that it does not damage it... "In the environment, it causes human eyes or other objects. A broken material can be mixed between the hairs." In the adhesive material, the hm is loaded and the situation is degraded. Sticky to the heart, don’t take the photo first. Deterioration of the material will result in poor adhesion, which will cause the illuminating body and the supporting carrier to be bad. The breaking material is selected from the organic light stabilizer «Inorganic ultraviolet light, v-.
