[0002] The LED lamp is encapsulated with a reflector cup and a lens at the light-emitting chip, and the emitted light is adjusted by the reflector cup and the lens in turn. In this case, the reflector cup and the lens need to be fixed together. The most common method is to glue the lens to the mouth of the reflector cup with glue. However, this fixing method is prone to problems because the contact surface between the reflector cup and the lens is a single plane, and the reflector cup is generally cup-shaped, with a small contact surface on the edge of the cup. If it is a small lamp like a lamp bead, the contact surface is even smaller, resulting in the reflector cup and the lens being too simple to contact and stick, prone to loosening, and poor fixing reliability.

[0003] Therefore, in the prior art, the combined contact surface of the reflector cup and the lens is too simple, and the reliability of the combined fixation is poor. Summary of the invention

[0010] In a feasible embodiment, the groove is a non-linear groove in the length direction, including but not limited to a curve or a broken line, so that when part of the light emitted by the light source enters the groove, it is reflected by the inner wall of the groove and then emitted.

[0011] In a feasible embodiment, the cross section of the groove is trumpet-shaped from the bottom upward.

DETAILED DESCRIPTION

[0038] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by technicians in this field without creative work are within the scope of protection of the present invention.

[0039] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inside" and "outside" are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0040] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0041] Example 1

[0042] See also Figure 1-2 ,in Figure 1 This is a schematic diagram of the three-dimensional structure of the LED bracket. Figure 2 It is a top view of an LED bracket. This embodiment provides an LED bracket 100, which includes a substrate 200 and a reflector cup body 1; the reflector cup body 1 is arranged on the substrate 200, and a reflector cup cavity 2 is arranged on the reflector cup body 1, and the reflector cup cavity 2 is used to accommodate the LED chip arranged on the substrate 200; at least one groove 3 is arranged on the reflector cup body 1 through the cup wall, and the groove 3 is combined with the reflector cup cavity 2 to form an installation and fixing space for the lens.

[0043] It can be understood that the LED lamp mainly includes a substrate 200 and an LED chip and a corresponding circuit arranged on the substrate 200. The corresponding LED chip and circuit belong to conventional technical content and will not be further described here. Those skilled in the art can refer to the existing technology to understand and implement them. The reflector cup body 1 is arranged on the substrate 200 and surrounds the LED chip. The reflector cup cavity 2 arranged on the reflector cup body 1 actually penetrates the reflector cup body 1 from top to bottom, so that one side of the LED chip arranged in the reflector cup cavity 2 is fixedly arranged on the substrate 200; in the process of mass production of small LED lamps (LED lamp beads), the reflector cup body 1 can be formed by compression molding on the substrate 200. The material of the reflector cup body 1 can be common materials such as glass, plastic, aluminum alloy, etc. In this embodiment, the reflector cup body 1 can be produced separately or molded on the substrate 200. There is no strict restriction in this embodiment. Compression molding (also known as press molding or compression molding) is to first put powdered, granular or fibrous plastic, glass or other materials into a mold cavity at a molding temperature, and then close the mold and pressurize it to form and solidify it. Compression molding belongs to a mature existing technology and will not be further described here. Those skilled in the art can understand and implement it in combination with the above description.

[0044] Further, such as Figure 1 As shown in , if a single LED lamp is produced, a LED bracket 100 can be molded separately and then a single lens can be molded; Figure 3 As shown, Figure 3 This is a schematic diagram of the structure of the batch LED bracket 100 provided in the present embodiment. If it is a small-scale LED lamp produced in batches, a batch array layout can be used to design a number of lamp groups, and a corresponding number of LED brackets 100 are uniformly formed. After the LED brackets 100 are molded, the lenses are uniformly molded. The molded molding of the lenses can also be designed according to the number of LED brackets 100. Specifically, if there are multiple LED brackets 100, after the LED brackets 100 are formed by batch molding, the lenses are batch molded so that the lenses and the LED brackets 100 are combined and fixed, and then they can be used as a whole page or divided into individual LED lamp beads as needed. More details are not further described here.

[0045] It is understandable that if a single lamp is produced and processed, the process of molding the LED bracket 100 and the lens one by one when mass production is required will be very cumbersome and inefficient, and the groove 3 provided in the present invention is not only convenient for combining and fixing the lens, but also convenient for mass production. Figure 3As shown in the figure, the grooves 3 of two adjacent LED brackets 100 are interconnected. Then, when the lens is molded, the grooves 3 can make the reflector cup cavities 2 of each LED bracket 100 connected, so that the lens molding material flows, so that the entire version of the lens can be molded at one time, which greatly improves the efficiency of mass production. In the later stage, the entire version of LED lamps can be formed as needed, or they can be divided into single independent lamps.

[0046] In the embodiment of the present invention, Figure 1 As shown in , the grooves 3 are provided in a plurality of rows, and the grooves 3 are evenly spaced and arranged in the circumferential direction of the reflector cup body 1 , so as to divide the upper portion of the wall of the reflector cup body 1 into a plurality of blocks 11 .

[0047] It is understandable that, for setting the reflector cup body 1 on the substrate 200, there will be a stress difference due to the difference in material and structure between the reflector cup body 1 and the substrate 200, and the thickness of the substrate 200 is less than the height of the reflector cup body 1. Specifically, for example, in the case where the reflector cup body 1 is formed by compression molding as exemplified in this embodiment, there is a stress difference between the reflector cup body 1 itself and the substrate 200 after compression molding, so that the substrate 200 is subjected to the stress of the reflector cup body 1, thereby causing the substrate 200 to deform. Therefore, in this embodiment, by providing the groove 3, the reflector cup body 1 can be divided into a plurality of small blocks 11, thereby reducing the stress of the reflector cup body 1 and reducing the impact on the substrate 200.

[0048] It can be understood that, although four grooves 3 are evenly spaced on the reflector cup body 1 illustrated in the present embodiment, it does not exclude the possibility that a greater number of grooves 3 are provided in other embodiments. In theory, providing one groove 3 can also reduce the internal stress of the reflector cup body 1. Those skilled in the art can set the number of grooves 3 according to actual conditions. More situations will not be further described here.

[0049] In the embodiment of the present invention, Figure 4As shown, it is a schematic diagram of the cross-sectional structure of the LED bracket 100 provided in this embodiment, and the depth h of the groove 3 is greater than half of the height H of the reflector cup body 1, and less than the height H of the reflector cup body 1. In this embodiment, the groove 3 can be used as a connecting and matching structure between the lens and the LED bracket 100, and can also play a role in reducing the stress of the reflector cup body 1 on the substrate 200. In this case, the depth h of the groove 3 is set to be greater than half of the height H of the reflector cup body 1. The larger h is, the smaller the stress of the reflector cup body 1 on the substrate 200. It can be understood that if the LED lamp is manufactured by plate production, then the thickness between the groove 3 and the substrate 200 (the gap between the mold core and the substrate 200 before the reflector cup body 1 is molded) can be used as the flow channel of the molding material during molding, so the depth h of the groove 3 can be set to be less than the height H of the reflector cup body 1, so as to facilitate plate molding to form a plurality of reflector cup bodies 1.

[0050] In the embodiment of the present invention, Figure 5 As shown, it is a schematic diagram of the structure of the groove provided in this embodiment. In this case, the first notch 31 of the groove 3 located on the inner wall of the reflector cup body 1 and the second notch 32 located on the outer wall of the reflector cup body 1 are staggered along the center direction of the reflector cup body 1, so that when part of the light emitted by the light source enters the groove 3, it is reflected by the inner wall of the groove 3 and then emitted.

[0051] Specifically, Figure 6 , which is a schematic diagram of another groove structure provided in this embodiment, in which the first notch 31 and the second notch 32 are arranged along the center direction of the reflector cup body 1. In this case, after the LED chip arranged at the center of the reflector cup body 1 emits light, the light leaking from the groove 3 directly enters from the first notch 31 and directly exits from the second notch 32 without any refraction or reflection, and the light is relatively strong. Therefore, in order to minimize the light leakage from the groove 3 in this embodiment, as shown in FIG. Figure 5 The slots at both ends of the groove 3, namely the first slot 31 and the second slot 32, are staggered. The advantage of this arrangement is that when light leaks from the groove 3, it can be reflected multiple times by the inner wall of the groove 3 to reduce the loss, thereby weakening the light intensity and reducing light leakage.

[0052] It can be understood that the staggered arrangement between the first notch 31 and the second notch 32 means that the center positions of the first notch 31 and the second notch 32 and the center of the reflector cup body 1 are not on the same straight line. Figure 5 In the diagram of FIG. 1 , the first notch 31 and the second notch 32 are staggered for staggered arrangement only as an illustration, and those skilled in the art can make simple modifications according to the above situation, such as changing the groove 3 from Figure 5The purpose described in this embodiment can be achieved by changing the straight-line groove into a curved or broken-line groove, and no further description of more situations will be given here.

[0053] In the embodiment of the present invention, Figure 7 As shown, it is a schematic diagram of another groove shape provided in this embodiment, and the groove 3 is a non-linear groove in the length direction, including but not limited to a curve or a broken line shape, so that when part of the light emitted by the light source enters the groove 3, it is reflected by the inner wall of the groove 3 and then emitted.

[0054] It can be understood that the main purpose of this embodiment is to design the groove 3 so that when part of the light emitted by the light source located at the center of the reflector cup body 1 enters the groove 3, it will be reflected by the inner wall of the groove 3 to weaken the light intensity, thereby achieving the purpose of reducing light leakage. Therefore, as long as the inner wall of the groove 3 is not directly along the direction of the center of the reflector cup body 1. Based on this, if Figure 5 as well as Figure 7 As shown in the figure, the first notch 31 and the second notch 32 can be staggered, and the shape of the groove 3 can also be designed to be non-linear according to actual needs. The non-linear shape mainly refers to a curve, a broken line or a combination of the two. Those skilled in the art can choose one or a combination of them according to actual needs, and no further schematic description will be given here.

[0055] In the embodiment of the present invention, Figure 4 As shown, the cross section of the groove 3 is trumpet-shaped from the bottom to the top. It is understandable that the formation of the reflector cup body 1 can generally be carried out by compression molding. In this embodiment, the cross section of the groove 3 is trumpet-shaped from the bottom to the top, so as to facilitate demoulding when the reflector cup body 1 is compression molded. The trumpet shape specifically means that the width of the cross section of the groove 3 from the bottom to the top is set from narrow to wide, which includes the situation that the inner wall of one side of the groove 3 is inclined relative to the bottom, and the inner wall of the other side is perpendicular to the bottom or also inclined relative to the bottom, so that the cross section of the groove 3 is trumpet-shaped. It is understandable that in order to facilitate demoulding, in addition to the trumpet-shaped structure of the groove 3 in this embodiment, those skilled in the art can also use conventional technical means to design it according to actual needs, such as rounded corners and arc transitions at corners, etc. More details are not further described here.

[0056] In the embodiment of the present invention, the LED bracket 100 can be obtained by molding the reflector cup body 1 on the substrate 200 through compression molding, and then the lens can be molded on the LED bracket 100 through compression molding. Specifically, the lens can be molded into the groove 3 and combined with the reflector cup cavity 2 to form an installation and fixing space for the lens, thereby completing the combined installation of the LED bracket 100 and the lens.

[0057] Due to the adoption of the above technical solution, the LED bracket 100 provided by the present invention has at least the following beneficial effects:

[0058] The LED bracket 100 provided by the present invention is provided with at least one groove 3 penetrating the cup wall along the center direction of the reflector cup on the reflector cup body 1. The groove 3 is combined with the reflector cup cavity 2 to form an installation and fixing space for the lens. Therefore, when installing the combined lens, the lens can be designed to be installed in a shape that cooperates with the installation and fixing space, so that a spatial contact surface is formed between the lens and the reflector cup for contact and fixing. The contact surface is large and belongs to spatial contact. At the same time, due to the existence of the groove 3, the lens can be prevented from rotating relative to the reflector cup, which is more reliable and stable than a single plane contact and fixing combination method.

[0059] Example 2

[0060] See also Figure 8 , is a schematic diagram of the structure of an LED packaging device provided in this embodiment. The LED packaging device provided in this embodiment includes:

[0061] The LED bracket 100 described in the above embodiment;

[0062] LED chip, the LED chip is arranged on the substrate 200, and the substrate 200 is a PCB substrate;

[0063] and a lens 300, wherein the lens 300 is connected to the groove 3 and the reflector cup cavity 2 ( Figure 8 The reflector cup cavity 2 is not shown in the figure, and can be combined with the above-mentioned embodiment. Figure 1 For understanding) is arranged on the LED bracket 100.

[0064] It is understandable that the substrate 200 is provided with LED chips and circuits required for the operation of the LED lamp. The types and configurations of the circuits and chips are conventional technical means in the art and will not be further described here.

[0065] It is understandable that the material of the lens 300 can be silicone, glass or PMMA lens 300, which can be selected according to actual needs, and will not be further described here. The corresponding LED chip and circuit belong to conventional technical content, and will not be further described here. Those skilled in the art can refer to the existing technology to understand and implement it.

[0066] In the embodiment of the present invention, Figure 8As shown, the LED bracket 100 is provided with one, and the LED chip provided in the reflector cup cavity 2 of the LED bracket 100 is one or more. It is understandable that for the LED chip, the common type and specific setting quantity in the prior art can be selected according to actual needs, for example, two LED chips with different light colors or other quantities can be provided, and the specific setting can be based on specific needs, and no further description is given here.

[0067] In the embodiment of the present invention, Fig. 9 FIG. 1 is a schematic diagram of the structure of another LED packaging device provided in this embodiment. The LED bracket 100 is provided in plurality. Fig. 9 The vertical dotted line in the middle is used as a dividing line, and reference can also be made to the above embodiment. Figure 3 It is understood that the plurality of LED brackets 100 are arranged in a matrix, and the grooves 3 of two adjacent LED brackets 100 in the same row or column are connected to each other.

[0068] It is understandable that the LED package device can be manufactured and used as a single LED lamp, or it can be manufactured and used as a panel of multiple LED package devices. Figure 8 As shown in , if a single LED package device is produced, a LED bracket 100 can be molded on a substrate 200 and then a single lens 300 can be molded; Fig. 9 As shown, if it is a mass-produced LED packaging device, a batch array layout can be used to design several lamp groups, and a corresponding number of LED brackets 100 are uniformly formed on the substrate 200. After the LED brackets 100 are molded, the lenses 300 are uniformly molded. The molding of the lenses 300 can also be designed according to the number of LED brackets 100. Specifically, if there are multiple LED brackets 100, after the LED brackets 100 are molded in batches, the lenses 300 are molded in batches so that the lenses 300 are combined and fixed with the LED brackets 100. Then, they can be used as a whole page or divided into individual LED packaging devices as needed. More details are not further described here.

[0069] It is understandable that if a single LED package device is to be produced and processed, it will be more complicated to mold a single LED bracket 100 and lens 300 when mass production is required. The groove 3 provided in the present invention is not only convenient for combining and fixing the lens 300, but also convenient for mass production. Combined with the description of the previous embodiment, the grooves 3 of two adjacent LED brackets 100 are interconnected. Then, when the lens 300 is molded, the groove 3 can make the reflector cup cavity 2 of each LED bracket 100 communicate with each other, so that the molding material of the lens 300 flows, so that the entire version of the lens 300 can be molded at one time, which greatly improves the efficiency of mass production. In the later stage, the entire version of LED lamps can be formed according to needs, or they can be divided into single independent lamps.

[0070] The contents not introduced in this embodiment can be understood and implemented in combination with the previous embodiments and will not be further repeated here.

[0071] The LED packaging device provided in this embodiment uses an LED bracket 100 designed with a groove 3, combined with a lens 300 to form an LED packaging device that can reduce the deformation effect of the stress of the reflective cup body 1 on the substrate 200, and can also make the fixed connection between the lens 300 and the LED bracket 100 more reliable.

[0072] Example 3

[0073] like Fig.10 As shown, Fig.10 Flow chart of an LED packaging method provided in this embodiment. An LED packaging method provided in this embodiment of the present invention is used to manufacture the LED packaging device described in the above embodiment, comprising:

[0074] Step S1: forming a plurality of reflector cup bodies by integral molding on a PCB substrate, wherein at least one groove is provided on the reflector cup body through the cup wall, and the grooves of two adjacent reflector cup bodies are connected to each other;

[0075] Step S2: solid crystal;

[0076] Step S3: forming a lens by integral molding on the reflector cup body, wherein the groove and the reflector cup cavity are combined to form a mounting and fixing space for the lens, thereby obtaining an LED packaging module composed of a plurality of LED packaging devices;

[0077] Step S4: dividing the LED packaging module to form LED packaging devices.

[0078] It is understandable that die bonding is also called Die Bond or chip mounting. Die bonding is a process of bonding the chip to the designated area of ​​the bracket through a colloid (generally conductive glue or insulating glue for LEDs) to form a thermal path or an electrical path to provide conditions for subsequent wire bonding. More specific content will not be further described here. Those skilled in the art can understand and implement it based on the above description in combination with the prior art. Specifically, the corresponding circuits and other conventional components can be printed on the PCB substrate in advance, and the DB (chip mounting) and WB (wire bonding) processes can be performed in accordance with the conventional LED operation method after step S1. Such processes and components belong to the conventional operations of LED lamp production and will not be further described here.

[0079] It can be understood that compression molding (also known as press molding or compression molding) is an operation in which powdered, granular or fibrous plastics, glass or other materials are first placed into a mold cavity at a molding temperature, and then the mold is closed and pressurized to form and solidify them. Compression molding is a mature prior art and will not be further described here. Those skilled in the art can understand and implement it in combination with the above description.

[0080] It is understandable that if Fig.11 As shown, it is a schematic diagram of a mold forming a reflector cup body given in this embodiment. In step S1 of this embodiment, the substrate 200 is clamped between the first upper mold core 400 and the first lower mold core 500, and a first glue injection area 600 is formed between the first lower mold core 500 and the substrate 200. After the first glue injection area 600 is injected and molded, it becomes the corresponding reflector cup body 1. It can be understood that if it is a finished LED packaging module containing multiple LED brackets 100, as described above in the present invention Figure 3 As shown, two adjacent first injection areas 600 are actually connected, that is, the reflective cup bodies 1 of adjacent LED brackets 100 of the finished LED packaging module are interconnected, so that the reflective cup bodies 1 of the finished LED packaging module can be formed by one-time injection.

[0081] It is understandable that if Fig.12As shown, it is a schematic diagram of a molding method for forming a lens in this embodiment. In step S3 of this embodiment, the substrate 200 and the reflector cup body 1 (i.e., the LED bracket 100) are clamped between the second upper mold core 700 and the second lower mold core 800, and a second glue injection area 900 is formed between the second lower mold core 800 and the reflector cup body 1. After the second glue injection area 900 is injection-molded, the corresponding lens 300 and the lens structure arranged in the groove 3 are formed. It can be understood that if it is a finished LED packaging module containing multiple LED brackets 100, the two adjacent second glue injection areas 900 are connected through the groove 3, and the groove 3 is used as the flow channel of the material when the lens 300 is molded into a plate, so that the finished lens 300 can be formed by one-time injection molding, which is convenient for the batch production of LED lamps.

[0082] The LED packaging method provided in this embodiment can quickly and effectively manufacture an LED packaging device in which the LED bracket 100 and the lens 300 are reliably connected and fixed, and is also convenient for batch production and improves production efficiency.

[0083] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
