New Description: [New Technology Field] This creation is about a package structure of a light-emitting diode, especially for a lens holder that uses a lens holder to fix the optical lens to the base and can be quickly The technical field of replacing optical lenses. [Prior Art] A light-emitting diode (LED) is a principle that directly converts light into light energy by using electric energy. A voltage is applied to two terminals of the positive and negative electrodes in the semiconductor, and when the current passes, the electrons and the hole are combined to release energy. Release in the form of light, this is the principle of illumination of a light-emitting diode. The light-emitting diodes have different energy levels depending on the materials used, so that the photon energy produces light of different wavelengths. The light-emitting diode has the advantages of light weight, fast response and no pollution. These advantages make the application field of the light-emitting diode gradually span various industries, and gradually develop a high-power light-emitting diode to solve the problem of insufficient brightness. The problem is that the diode can also be used in the field of lighting sources, and there is a tendency to gradually replace the traditional wire lamp' is the potential to replace traditional lighting in the future. The light-emitting diode is mainly composed of a pedestal, a light-emitting diode chip, an optical lens and a lens holder. The pedestal provides a bearing of the light-emitting diode chip and an electrode connection. In structure, the optical lens is usually fixed by a lens. The seat is fixed to the base, or the adhesive lens is used to adhere the lens to the base. The structure is as shown in US Patent No. 2004/0126913, the LED is assembled on a lead frame, and the optical lens is coupled to the pedestal or the reflector; or, as in the patent JP3191580, the use of electric contacts 6 The M338431 light-emitting diode chip is fixed with the optical lens; or, as in the Russian patent WO2006109113, the optical lens is fixed through a substrate by a melted plastic indexing means; or, as in Taiwan patent TW238542, a thread or a plug is used. The Socket is fixed; or, as in Japanese Patent JP2007080879, an optical lens is used to hook the pedestal; other various assembly structures such as Japanese Patent JP2000150968, US Patent No. 5440468, US506877, US2007023CH, US2004190304, USC139139931, and the like. Because the adhesive is filled between the LED chip and the optical lens to fix the optical lens and the pedestal, the brightness may be affected by the aging of the adhesive or the yellowing of the adhesive; and the optical lens is fixed by using the lens holder. The method is a practical structure such as Japanese Patent JP60198412. As shown in Fig. 1, a side view of a package structure using a light-emitting diode of a lens holder is shown. In the figure, the agricultural structure 1 comprises a base 10, an LED die 11, an optical lens 12 and a lens holder 13. The LED chip 11 is disposed on the susceptor 10, and the lens 12 covers the illuminating diode chip and is placed between the lens holder 13 and the pedestal 1 且 and passes through the opening of the shovel holder 13 . The surface of the susceptor 10 has at least a through hole, and the support post 131 of the lens holder 13 passes through the through hole 1〇1, and the support post that exposes the support post 131 to the through hole 1〇1 exposes the through hole portion. The heat is melted to deform, so that the support post 131 cannot be detached from the through hole, and the 19 to the lens mount 13 fixes the optical lens 12 to the base, and the structure can be used to fix the optical lens. It can be prevented properly. The expansion causes the optical lens to be separated from the pedestal, especially for special light-cured LEDs; the special light-type LEDs are structurally more in need of optical lenses and 旯 7 M338431 can be firmly combined. However, such a structure is difficult to achieve the effect of positioning the optical lens and the base, and it is necessary to use the heat fusion to deform the support post 131, which makes it difficult to achieve rapid assembly. With the increasing popularity of light-emitting diodes, the field of application is becoming wider and wider, and the demand for light-emitting diodes that produce special light patterns is increasing, as shown in Figure 2. A light-emitting diode that emits a 'pentagonal light' type. However, such a light-emitting two-pole body capable of producing a special light type requires strict positioning of the optical lens in the package structure, because the position of the optical lens is slightly changed, or the optical lens is slightly rotated, which may affect The light quality of such a light-emitting diode. In the above-mentioned conventional packaging structure, the lens holder 13 and the optical lens 12 are fixed to the base 1 only by the support post 131 of the lens holder 13 being defined in the through hole ιοί, but After a long period of use, the package structure is inevitably subjected to external force sway or vibration, so that the support post exposed through hole portion 19 cannot limit the support post 131 to the through hole 1〇1, so that the lens mount 13 may be loosened. The movement or rotation of the optical lens 12 affects the illuminating light pattern of the light-emitting diode. In particular, if a polarizer is formed by using a glue or a support column 131 to be thermally dissolved, the light-emitting diode is mounted on a lamp or other illuminator, and the light pattern is fixed to the light-emitting diode by the optical lens. It cannot be changed; when there is a need to replace the light type, the entire group of light-emitting diodes must be replaced, which causes inconvenience and cost. To improve the problems raised above. Based on many years of research and many practical experiences, this creator has been researching and designing and discussing the topic. 遂 8 M338431 proposed a package structure of light-emitting diodes in this creation as the realization and basis of the above-mentioned expectations.

The effect of time makes it possible to quickly change the optical lens without damaging the lens holder. In addition, the inner wall surface 234 of the lens holder 23 may further have a reflection layer, for example, an inner surface _ 234 plated with silver or silver, sprayed with a base or a silver-based substance to form A film 'layer to enhance the reflection of the inner wall surface 234. In addition, the shape of the base 2 can be changed as needed, and is not limited to the square shown in Fig. 3. The base of other shapes is also within the protection scope of the present invention. Please refer to FIG. 5, which is a schematic exploded view of the second embodiment of the package structure of the light-emitting diode of the present invention. In the figure, the package structure 3 is different from the package structure 2 in that the optical lens 32 included in the package structure 3 has at least one lens stem 322, and the surface of the base 3 has at least one lens correspondingly. Positioning hole cavity) 301. The optical lens 32 is positioned on the base 30 by the lens positioning post 322 being embedded in the lens positioning hole = 〇1. Thereby, the optical lens 32 can be preferably positioned on the base 30 to reduce the possibility of the optical lens 32 moving or rotating due to external force swaying or vibration of the package structure 3. "Monthly, Fig. 6 is a schematic exploded view showing the third embodiment of the package structure of the light-emitting diode of the present invention. In the figure, the package structure 4 differs from the package structure 2 in that the package lens 4 is formed by plastic injection molding, and has at least one lens alignment 423, which is aligned. The portion 423 can be disposed in the mold of the plastic injection 13 M338431, and is simultaneously formed into the pear at the same time as the optical lens 42. The inner wall 234 of the opening of the fixing seat 43 has a corresponding to = and the wafer seating alignment portion (holder) Alignment) 439. When the lens holder is fixed to the base 20, the lens holder 43 is coupled to the lens alignment portion 423 by the fixed jaw A 43 439 to position the optical lens 42. The aligning plate holder 43 preferably fixes and fixes the optical lens 42 to reduce the possibility that the package structure 4 is shaken or shaken by an external force; the susceptor optical lens 42 moves or rotates. Therefore, the lens positioning hole 'the lens positioning post, the winding piece and the fixing seat alignment part can be used in combination, and is not limited to the description of the quasi-solid part, that is, the optical lens can also have the lens at the same time. See <See the lens alignment part, and the lens holder and the base respectively have a fixing & and a positioning hole of the lens, thereby achieving better positioning and fixing the age-rate. Please refer to FIG. 7 , which is a schematic exploded view of the fourth embodiment of the light-emitting surface of the present invention. In the figure, the surface is different from the above-mentioned package structure in that the package structure 5 is surrounded by the S-seat 50 and the lens holder 53 in a circular shape, and is applied in the same manner. In the present embodiment, the optical lens 42 is spliced into a glass preform or a glass material in a mold without a product specification, and is subjected to heating and casting. If it is used for a white LED, an optical lens 42 made by a phosphor powder infiltrated glass surface (pigs) manufacturing technology can be used to infiltrate the glory powder on the surface of the lens to emit the LED. The light conversion wavelength becomes white light. In the embodiment, the glass precision molding manufacture technology has a fixing seat positioning hole 201 on the surface of the base 14 of the M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M The fixing frame 232 and the hook structure 233 are fixed to the base 20 by the hook structure 233, and the positioning post 232 is embedded in the fixed seat. The hole 201 is positioned on the base 50 „, whereby the lens holder 53 can fix the optical lens 22 to the base 50 without being restricted by the shape of the base and the lens holder. Because of this, the structure is simple. The rigid glass material φ optical lens 42 is easily fixed and positioned by using the lens holder 53.
