Description

Technical field

[1] The present invention relates to a set of LED output frames, an LED group using an LED output frame, and a method for manufacturing an LED group, and in particular, to a set of LED output frame that can be easily manufactured with reduced manufacturing costs an LED group using the LED output frame kit, and a method for manufacturing the LED group.

State of the art

[2] A light emitting diode (LED) is a semiconductor lighting device having various advantages over conventional lighting devices. For example, the LED has a long life, compact size, low power consumption and does not lead to mercury pollution. Accordingly, LEDs are often used as new lighting devices instead of conventional lighting devices.

[3] In order to increase the light output of the LED group, a convex lens-like structure is usually used on the external optical layer of the LED group. In conventional LED groups, a convex lens-shaped structure is prefabricated and then mounted on a conventional LED group. Because of this additional production of the structure in the form of a convex lens and its assembly process, an additional manufacturing process and mounting device are required. Moreover, when mounting a structure in the form of a convex lens made in advance on a conventional LED group, an undesirable layer of air may form between the structure in the form of a convex lens and a sealing layer that is already made on the LED group. In addition, in accordance with conventional technologies, when forming a sealing layer on the LED matrix to protect the LED matrix, it is difficult to form a convex bend on the outer surface of the sealing layer. Accordingly, the productivity of the method of manufacturing the LED group in accordance with conventional technologies is relatively low, and the cost is high.

[4] In order to provide a white LED for emitting white light, a phosphor layer is typically directly applied to the matrix of a blue LED or an ultraviolet (UV) LED. For example, when a blue LED matrix is used, lights of different wavelengths generated in the phosphor material can be mixed with each other, or lights with different wavelengths can be mixed with the excited blue light emitted by the blue LED matrix, thereby emitting white light . However, when the LED matrix is directly coated with the phosphor layer, since the LED matrix and the phosphor layer are very close to each other, the light emitted by the phosphor material passes to the LED matrix and is absorbed by the LED matrix.

[5] Thus, it was proposed to place a transparent insert between the LED matrix and the phosphor layer so that the light emitted from the phosphor layer does not fall on the LED matrix or base near the LED matrix, thereby reducing the likelihood of light absorption. Figure 1 illustrates an example of the above technology disclosed in US patent No. 5,959,316. Referring to FIG. 1, the LED matrix 60 is mounted on the base 62, and the phosphor layer 66 is separated from the LED matrix 60 by an insert 64 covering the LED matrix 60. In addition, the protective layer 68 is formed outside of the phosphor layer 66. However, light is also in this structure emitted by the phosphor layer 66 may fall back onto the LED array 60 and onto the base 62 and thus be absorbed with little or no interference.

The best embodiment of the invention

[35] The present invention will be described in more detail with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. The same reference numerals in the drawings indicate the same elements, and the dimensions of the elements are exaggerated for convenience and clarity of description.

[36] FIG. 2 is a perspective view of a structure of a set of LED output frames 20 in accordance with an embodiment of the present invention. Referring to FIG. 2, a set of LED output frame 20 includes a heat dissipation base 2, four electrodes 1 located around the heat dissipation base 2, and an insulating support part 3 that surrounds the heat dissipation base 2 and a plurality of electrodes 1 for connecting the heat dissipation base 2 and the plurality of electrodes 1 In this embodiment, the LED output frame 20 includes four electrodes 1, however, the present invention is not limited to them, and the LED output frame 20 may include one or more electrodes 1. Insulation The supporting part 3 may be made of plastic insulating material such as polyphthalamide (PPA).

[37] FIG. 3 is a plan view of the LED output frame 20 in FIG. 2. Referring to FIG. 3, the LED output frame 20 includes four identical metal electrodes 1 that are located in the radial direction. Four electrodes 1 can be respectively located at an angle of 90 degrees around the central axis of the heat dissipating base 2 and protrude in a radial direction from the center axis of the heat dissipating base 2. Figure 4 is an axonometric view schematically illustrating the location of the heat dissipating base 2 and four electrodes 1, without insulation supporting part 3. Referring to FIG. 4, the upper surfaces of the four electrodes 1 are at the same height as the highest point of the heat dissipation base 2. In addition, as shown in FIG. 2 to 4, the first end part of the electrodes 1 can be opposed to the lateral circumference of the heat dissipating base 2, and the second end part of the electrodes 1 can protrude from the outside of the insulating support part 3. The upper surfaces of the electrodes 1 can be coated, for example, with highly reflective materials such like silver or aluminum,

[38] Furthermore, referring to FIG. 4, the heat dissipation base 2 may have a reflective bowl 10 having a recess. The bottom surface of the reflecting bowl 10 may be coated with well-reflecting materials such as silver or aluminum. The upper surface of the reflecting bowl 10 is located at the highest point of the heat dissipating base 2. That is, the upper surface of the reflecting bowl 10 can be made at the same height as the upper surface of the electrodes 1.

[39] As shown in FIG. 4, the heat dissipation base 2 and the plurality of electrodes 1 are fixed by the insulating supporting part 3 that surrounds them. For this, the electrodes 1 of the heat dissipating base 2 and the insulating supporting part 3 can be made as a whole using injection molding.

[40] FIG. 5 is a cross section illustrating the structure of the LED output frame 20 in FIG. 2. Referring to FIG. 5 and FIG. 2, the LED output frame 20 may further include at least two annular protrusions, namely, annular protrusions 11, 12, 13 and 14, which are formed along the circumferential perimeter on the upper surface of the insulating supporting part 3 and, according to at least one annular groove, namely the annular grooves 15, 16 and 17, which are respectively formed between the two annular protrusions 11, 12, 13 and 14. The plurality of annular protrusions 11, 12, 13 and 14 and the plurality of annular grooves 15, 16 and 17 can be performed concentrically on the upper the surfaces of the insulating supporting part 3. As shown in FIG. 5, a plurality of annular protrusions 11, 12, 13 and 14 can be made with sharp edges and inclined sides.

[41] The plurality of annular protrusions 11, 12, 13 and 14 and the plurality of annular grooves 15, 16 and 17 may be made of the same PPA plastic as the insulating support part 3, and may be part of the insulating support part 3. For example, a plurality annular protrusions 11, 12, 13 and 14 and a plurality of annular grooves 15, 16 and 17 can be formed on the upper surface of the insulating support portion 3 by an injection molding process. In addition, a plurality of annular protrusions 11, 12, 13 and 14 and a plurality of annular grooves 15, 16 and 17 can be formed by injection molding, in which a plurality of electrodes 1, a heat dissipating base 2 and an insulating supporting part 3 are formed together. 5, four annular protrusions and three annular grooves are made, but the number of annular protrusions and annular grooves can be selected in accordance with various embodiments of the present invention.

[42] When the LED output frame 20 of the above structure, including a plurality of annular protrusions 11, 12, 13 and 14 and a plurality of annular grooves 15, 16 and 17, is used in the manufacture of the LED group, it is easy to form a sealing layer having a multilayer structure . 6 is a cross section illustrating the structure of the LED group 30 of the LED output frame 20, in which the output frame 20 is used in accordance with an embodiment of the present invention. Referring to FIG. 6, the LED group 30 includes an LED matrix 4 attached to the bottom surface of the heat dissipating base 2, a plurality of wires 6 electrically connecting the LED matrix 4 and electrodes 1, a sealing layer 7 made on the reflecting bowl 10 of the heat dissipating base 2, for coating LED matrix 4, phosphor layer 8, made to cover the sealing layer 7 and the optical lens layer 9, made to cover the phosphor layer 8.

[43] The LED matrix 4 can be mounted on the lower surface of the heat dissipating base 2, for example, using adhesive 5, that is, on the lower surface of the reflecting bowl 10 of the heat dissipating base 2. Examples of adhesive material for the matrix 5 can be silver paste and solder. In this embodiment, the LED group 30 includes one LED matrix 4 located on the lower surface of the heat diffusion base 2, however, the present invention is not limited to this, and the LED group 30 may include a plurality of LED arrays 4 located on the lower surface of the heat dissipation base 2 For example, at least one element selected from the group consisting of a UV LED, a blue LED, a green LED, and a red LED may be located on the bottom surface of the heat sseivayuschey base 2.

[44] The sealing layer 7, the phosphor layer 8, and the optical lens layer 9 constitute a multilayer structure of the sealing layer. For effective luminous flux, the sealing layer 7, the phosphor layer 8 and the optical lens layer 9 may have convex outer surfaces. In addition, so that the light emitted by the phosphor layer 8 does not fall on the LED matrix 4 and is not absorbed by the LED matrix 4, the effective refractive index of the sealing layer 7 may be less than that of the phosphor layer 8 in the wavelength range of visible light.

[45] The phosphor layer 8 emits visible light under the influence of ultraviolet light, blue light or green light. For this, the phosphor layer 8 can be made of a mixture in which a transparent material, such as glass, polycarbonate (PC), polymethyl methacrylate (PMMA), or silicone resin, is uniformly mixed with the phosphor material. Examples of the phosphor material include at least one type of phosphor material that emits visible light of different wavelengths under the influence of ultraviolet light, blue light or green light. For example, a phosphor material may be at least one element from the group consisting of various types of phosphor materials emitting visible light with different wavelengths, such as blue, green, yellow, orange or red light. Green, yellow, orange, and red phosphor material can partially absorb blue light, or at least green light, or completely absorb UV light, and emit a light spectrum with a peak wavelength in the green, yellow, orange, and red color wavelength ranges . In addition, the blue phosphor material can emit a light spectrum with a peak wavelength in cyan, which completely absorbs ultraviolet light.

[46] The LED group 30 emitting white light may be formed using the phosphor layer 8. For example, when the LED matrix 4 emits blue light in a wavelength range from 450 nm to 480 nm, the phosphor layer 8 can be excited by blue light, emitting light with a yellow peak wavelength. Then yellow light and residual blue light mix to form white light. In addition, the phosphor layer 8 may include various types of phosphor materials that emit light with different wavelengths under the action of light with an excitation wavelength emitted by the LED matrix 4. In this case, white light is emitted as light with different wavelengths and is mixed. For example, when the LED matrix 4 emits close to UV rays in the range from 380 nm to 450 nm, the phosphor layer 8 may include blue, green and red phosphor materials that emit light, respectively, having a blue, green and red peak wavelength under action close to UV rays. Then, as blue, green and red lights mix, white light forms.

[47] According to an embodiment of the present invention, the dimensions of the sealing layer 7, the phosphor layer 8 and the optical lens layer 9 and the curvature of their upper surfaces can be easily adjusted using a plurality of annular protrusions 11, 12, 13 and 14 and a plurality of annular grooves 15, 16 and 17. As shown in FIG. 6, the edge of the sealing layer 7 reaches the annular protrusion 11, the edge of the phosphor layer 8 reaches the annular protrusion 12, and the edge of the optical-lens layer 9 reaches the annular protrusion 13. Since the edges of the sealing layer 7, the phosphor layer 8 and the optical lens layer 9 are determined by the annular protrusions 11, 12 and 13, respectively, the dimensions of the sealing layer 7, the phosphor layer 8 and the optical lens layer 9 can be easily determined. Furthermore, by varying the amount of material of the sealing layer 7, the phosphor layer 8 and the optical lens layer 9 defined by the respective annular protrusions 11, 12 and 13, the curvature of the upper surface of the sealing layer 7, the phosphor layer 8 and the optical lens layer can be easily determined. 9.

[48] Hereinafter, the above-described method for manufacturing the LED group 30 will be described in detail. Firstly, a set of LED output frame 20, including a heat-dissipating base 2, a plurality of electrodes 1 located around the heat-dissipating base 2, an insulating supporting part 3 that surrounds the heat-dissipating base 2 with a plurality of electrodes 1 fixing it, a plurality of ring protrusions 11, 12, 13 and 14, made on the upper surface of the insulating supporting part 3, and a plurality of annular grooves 15, 16 and 17, respectively, made between two of the plurality of annular protrusions 11, 12, 13 and 14, are made using calling, for example, the injection molding process. Then, at least one LED matrix 4 is mounted on the lower surface of the heat dissipating base 2 using matrix adhesive material 5, and the LED matrix 4 and the plurality of electrodes 1 are electrically connected to each other via a plurality of wires 6.

[49] Further, a liquid transparent polymer is used to fill the reflective bowl 10 of the heat diffusion base 2 to coat the LED matrix 4. For example, the liquid transparent polymer may be a silicone resin. The liquid transparent polymer can be provided in sufficient quantity, being defined by the annular protrusion 11. Then, the outer surface of the liquid transparent polymer is formed convex due to surface tension in the upper sharp edge of the annular protrusion 11. For example, as shown in Fig. 8, when the transparent polymer 18 is provided in sufficient quantity within the annular protrusion 11, as a result of surface tension, a convex outer surface is formed. The curvature of the convex outer surface can be determined by the amount of the transparent polymer 18. Even if too much of the transparent polymer 18 is used and thus the transparent polymer 18 overflows the annular protrusion 11, the transparent polymer 18 can be redefined within the annular protrusion 12, as shown in FIG. .9. When the outer surface of the transparent polymer reaches the desired curvature in this way, the liquid transparent polymer 18 is solidified by heating or irradiation with UV rays, thereby forming a sealing layer 7. Accordingly, the size and curvature of the sealing layer 7 can be easily determined.

[50] Then, another liquid transparent polymer with which the phosphor material is uniformly mixed is formed over the sealing layer 7 to cover the sealing layer 7. For example, a mixture in which the liquid silicone resin and the phosphor material are uniformly mixed can be formed over the sealing layer 7 The mixture is limited to the annular protrusion 12 and has a convex outer surface in the sharp upper edge of the annular protrusion 12 due to surface tension. After the outer surface of the mixture reaches the desired curvature, the liquid mixture undergoes solidification by heating or irradiation with UV rays, thereby forming a phosphor layer 8.

[51] Finally, another liquid transparent polymer is formed over the phosphor layer 8 to cover the phosphor layer 8. For example, the liquid transparent polymer may be a silicone resin. The liquid transparent polymer on top of the phosphor layer 8 is limited to the third annular protrusion 13 and has a convex outer surface in the sharp upper edge of the third annular protrusion 13 due to surface tension. Then, the liquid transparent polymer, on top of the phosphor layer 8, is solidified in the form of an optical lens layer 9. Thus, a sealing layer 7, a phosphor layer 8 and an optical lens layer 9 of the desired size and desired external surface curvature can be made.

[52] FIG. 7 shows a cross section illustrating the structure of an LED output frame 40 according to another embodiment of the present invention. Unlike the LED group 30 in FIG. 6, the LED group 40 in FIG. 7 includes two sealing layers, namely, the first and second sealing layers 7 and 7a, under the phosphor layer 8. That is, the second sealing layer 7a, which will be being transparent, is formed between the phosphor layer 8 and the first sealing layer 7. The remaining structural elements of the LED group 40 in Fig. 7 are the same as that of the LED group 30 in Fig. 6. Thus, a description of the remaining structural elements of the LED group 40 will be omitted.

[53] In FIG. 7, the first sealing layer 7, the second sealing layer 7a, the phosphor layer 8 and the optical lens layer 9 together form a multilayer structure of the sealing layer. For efficient luminous flux, the first sealing layer 7, the second sealing layer 7a, the phosphor layer 8 and the optical lens layer 9 may have convex outer surfaces. In addition, so that the light emitted by the phosphor layer 8 does not fall on the LED matrix 4 and is not absorbed by the LED matrix 4, the effective refractive index of the second sealing layer 7a is less than that of the phosphor layer 8 in the wavelength range of visible light, and also less than the first sealing layer 7.

[54] As shown in FIG. 7, the edge of the first sealing layer 7 extends to the annular protrusion 11, the edge of the second sealing layer 7a extends to the annular protrusion 12, the edge of the phosphor layer 8 reaches the annular protrusion 13, and the edge of the optical lens layer 9 extends to the fourth annular protrusion 14. After matching the edges of the first sealing layer 7, the second sealing layer 7a, the phosphor layer 8 and the optical lens layer 9 with the plurality of annular protrusions 11, 12, 13 and 14, respectively, the dimensions of the first herme can be easily determined a sealing layer 7, a second sealing layer 7a, a phosphor layer 8 and an optical lens layer 9. In addition, by selecting the amount of material, respectively, for the first sealing layer 7, the second sealing layer 7a, the phosphor layer 8 and the optical lens layer 9, defined by the plurality of annular protrusions 11, 12, 13 and 14, the curvature of the upper surface of the first sealing layer 7, the second sealing layer 7a, the phosphor layer 8 and the optical lens layer 9 can be easily determined.

[55] The structure of the sealing layer of the LED group 40 in Fig. 7 can be made using the above-described method of manufacturing the LED group 30. The difference between the LED groups 40 and 30 is that the second sealing layer 7a is formed before the phosphor layer 8 is formed above the first the sealing layer 7. That is, the first sealing layer 7 is formed first using the method described above, and then a liquid transparent polymer is applied to the first sealing layer 7 to cover the first sealing layer on layer 7. For example, the liquid polymer can be a transparent silicone resin. The liquid transparent polymer has a lower effective refractive index than the first sealing layer 7. For example, the silicone resin, which is a liquid, can be an additive to control the effective refractive index. The liquid transparent polymer on the first sealing layer 7 is located within the annular protrusion 12 and has a convex outer surface in the sharp upper edge of the annular protrusion 12 due to surface tension. Then, after solidification of the liquid transparent resin material over the first sealing layer 7 by high temperature or UV irradiation, a second sealing layer 7a can be formed. Then, in the same manner as described above, the phosphor layer 8 and the optical lens layer 9 are sequentially formed on the second sealing layer 7a. However, the material of the phosphor layer 8 is applied so as to have boundaries inside the annular protrusion 13, and the material of the optical-lens layer 9 so as to be contained inside the annular protrusion 14.

[56] The first sealing layer 7, the second sealing layer 7a, the phosphor layer 8 and the optical lens layer 9 described above are sequentially formed using a liquid material, but some of the layers can also be preliminarily performed using separate processes.

[57] For example, the phosphor layer 8 may be performed in advance. In this case, the first sealing layer 7 is formed in the reflecting bowl 10 to cover the LED matrix 4. Then, the liquid transparent resin used to form the second sealing layer 7a is used to fill the concave inner part of the phosphor layer 8, prefabricated with a concave inner part and convex outer part. Then, the phosphor layer 8, into which the transparent polymer is added, is turned over and applied to the first sealing layer 7, and then the transparent polymer is solidified by high temperature or UV radiation. Then, the second sealing layer 7a is formed between the first sealing layer 7 and the phosphor layer 8, and the phosphor layer 8 can be tightly fixed to the first sealing layer 7. Then, as described above, the optical lens layer 9 can be applied to the phosphor layer 8.

[58] In addition, the phosphor layer 8 and the optical lens layer 9 may be preformed. In this case, the finished phosphor layer 8 is fixed on the first sealing layer 7, as in the method described above. Then, the optical lens layer 9, which is prepared in advance, can be attached to the phosphor layer 8. In addition, only the optical lens layer 9 can be preformed. In this case, the first sealing layer 7, the second sealing layer 7a, and the phosphor layer 8 are formed sequentially using liquid material, and then the finished optical-lens layer 9 is attached to the phosphor layer 8.

[59] For the manufacture of a white light-emitting diode group, a multilayer structure of a sealing layer including a phosphor layer 8 as described above can be used. However, in the production of a color LED group emitting waves of a certain light, the LED matrix 4 emitting light with a given wavelength can be attached to the bottom surface of the heat dissipating base 2, and only one transparent sealing layer can be formed on the LED matrix 4. For example, as shown in FIG. 8, one transparent polymer 18 can be used to fill one of the first to fourth annular protrusions 11 to 14, and then solidify, thereby completing the color light LED diode output frame 20.

[60] Although the invention has been specifically shown and described with reference to its typical variations, it will be understood by those skilled in the art that various changes in form and detail can be made therein without departing from the spirit and scope of the invention, as defined by the following points.
