Description

Technical Field

[0001] The invention relates to the field of LED (Light Emitting Diode), and in particular to a high-intensity LED bracket, an LED and a light-emitting device. Background Art

[0002] Due to the advantages of LED such as rich colors, small size, environmental protection and energy saving, and long life, it has been widely used and promoted in various fields, such as but not limited to daily lighting, outdoor lighting, lighting decoration, advertising signs, car lighting or instructions, traffic signs, etc. Since the external environment in which LED is used in different fields is different, greater requirements are placed on the reliability of LED, among which the overall strength of LED is an important measure of LED reliability.

[0003] For existing LED brackets, see Figure 1-1 to Figure 1-2 As shown, it includes a plastic enclosure 10 forming a reflective cavity, a positive substrate 11 and a negative substrate 12 enclosed by the plastic enclosure 10, and an isolation zone 13 insulating and isolating the positive substrate 11 and the negative substrate 12, wherein a portion of the front area of ​​the positive substrate 11 and the negative substrate 12 is in direct contact with the plastic enclosure 10, which is called the enclosure contact area; the other portion is located at the bottom of the reflective cavity as a functional area, which can be used to carry LED chips and other possible electronic devices, as well as wiring, solid crystals and as a light reflection area. The existing LED bracket has the following problems:

[0004] The insulating isolation zone between the positive substrate and the negative substrate is perpendicular to the long side of the bracket and is arranged in parallel with the positive substrate and the negative substrate; and the insulating isolation zone is made of a relatively fragile insulating plastic material, and the width of the insulating isolation zone is relatively narrow, resulting in a small amount of plastic in the insulating isolation zone, and the insulating isolation zone is prone to breakage, which reduces the overall strength and reliability of the LED bracket and the LED made using the bracket;

[0005] The wall contact area and the functional area on the front of the positive substrate 11 and the negative substrate 12 are located on the same plane. Therefore, when moisture spreads along the junction between the side of the substrate and the plastic wall 10 to the front of the substrate, it is easy to enter the functional area through the wall contact area on the front of the substrate, causing a short circuit in the functional area, damage to the device, or even a dead light. Moreover, the functional areas of most substrates are plated with a metal silver layer, which is also easily corroded by moisture, causing functional defects. It can be seen that the existing LED bracket and the LED made using the bracket have poor moisture resistance. Summary of the invention

[0018] In an embodiment of the present invention, a height difference between a plane where the functional area is located and a plane where the wall contact area is located is greater than 0 and less than or equal to one quarter of the depth of the reflection cavity.

[0019] In one embodiment of the present invention, the functional areas of the positive substrate and the negative substrate are located at the bottom of the reflection cavity formed by the wall, the insulating protrusion is in direct contact with the inner side surface of the reflection cavity, and the height of the insulating protrusion is less than the height of the inner side surface of the reflection cavity.

[0020] In an embodiment of the present invention, the insulating protrusion and the insulating isolation zone are integrally formed, and / or the insulating protrusion and the insulating isolation zone are made of the same material.

[0021] In an embodiment of the present invention, the profile of the longitudinal section of the insulating protrusion along the height direction is an arc profile or a profile consisting of an upper transverse side, a lower transverse side, and an arc between the upper transverse side and the lower transverse side.

[0022] In order to solve the above problems, the present invention also provides an LED, comprising the LED bracket as described above and at least one LED chip, wherein the LED chip is arranged on the positive substrate and / or the negative substrate, and the positive pin and negative pin of the LED chip are electrically connected to the positive substrate and the negative substrate respectively.

DETAILED DESCRIPTION

[0076] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the following is a further detailed description of the embodiments of the present invention through specific implementation methods combined with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0077] Embodiment 1:

[0078] In order to solve the problem of poor overall strength of existing LED brackets, the high-strength LED bracket provided in this embodiment includes a positive substrate, a negative substrate and an insulating isolation belt. Functional areas are provided on the front sides of the positive substrate and the negative substrate. The insulating isolation belt is located between the positive substrate and the negative substrate to insulate the two, and an insulating protrusion is provided on at least one end of the front side of the insulating isolation belt, thereby increasing the material weight of the insulating isolation belt, and then increasing the overall weight occupied by the insulating isolation belt in the bracket, thereby improving the overall strength of the insulating isolation belt, and then improving the overall strength and reliability of the LED bracket with the insulating isolation belt and the LED made using the bracket.

[0079] In addition, the LED bracket provided in this embodiment also includes an insulating wall body that encloses the positive substrate, the negative substrate and the insulating isolation belt. The front sides of the positive substrate and the negative substrate have a functional area and a wall contact area that contacts the wall body, and the functional area and the wall contact area of ​​at least one of the positive substrate and the negative substrate are not arranged on the same plane. Therefore, the path between the wall contact area and the functional area of ​​the substrate can be extended, that is, the path for moisture to enter the functional area can be extended, thereby improving the moisture-proof performance of the LED bracket and the LED made using the LED bracket, improving the reliability and durability of the LED, making the LED better suitable for application scenarios in various environments, and being more conducive to the promotion and use of LEDs.

[0080] In one example, the functional areas on the front sides of the positive substrate and the negative substrate are located at the bottom of the reflection cavity formed by the surrounding wall.

[0081] The positive electrode substrate and the negative electrode substrate in this embodiment are both conductive substrates. The conductive substrate in this embodiment can be a substrate made of various conductive materials, for example, various metal conductive substrates, including but not limited to copper substrates, aluminum substrates, iron substrates, and silver substrates; the conductive substrate can also be a mixed material conductive substrate containing conductive materials, such as conductive rubber.

[0082] Optionally, in this embodiment, a reflective layer may be provided in at least one of the positive functional areas of the positive substrate and the negative substrate to improve the light extraction efficiency of the bracket. The reflective layer may be any light reflection layer that can improve the light extraction efficiency, including but not limited to a silver plating layer.

[0083] Optionally, in this embodiment, the back side of at least one of the positive electrode substrate and the negative electrode substrate is exposed at the bottom of the wall body as an electrode welding area. Of course, in some examples, the back side of at least one of the positive electrode substrate and the negative electrode substrate may not be used as a welding area, but its side surface may be used as a welding area, and the specific setting can be flexibly determined according to specific application requirements.

[0084] Optionally, in this embodiment, the enclosure body can be made of various insulating materials, such as, but not limited to, various plastics, insulating ceramics, etc. For example, in one example, the materials that can be used for the enclosure body include, but are not limited to, epoxy resin (EP), high temperature resistant nylon (PPA plastic), polyphthalamide (PPA), poly1,4-cyclohexylene dimethyleneterephthalate (PCT), liquid crystal polymer (LCP), sheet molding compound (SMC), epoxy molding compound (EMC), unsaturated polyester (UP) resin, polyester resin (PET), polyethylene terephthalate), polycarbonate (PC), polyhexamethylene adipamide (nylon 66), and glass fiber.

[0085] Optionally, the material of the insulating isolation zone in this embodiment may be the same as or different from that of the surrounding wall, and it may be formed together with the surrounding wall or formed separately.

[0086] In addition, it should be understood that the method for forming the surrounding wall in this embodiment can also be flexibly selected, for example, it can be formed by but not limited to injection molding.

[0087] In one example of this embodiment, insulating protrusions may be provided at both ends of the front side of the insulating isolation belt to further enhance the strength of the insulating isolation belt. When insulating protrusions are provided at both ends of the insulating isolation belt, the shapes, sizes, and materials of the insulating protrusions at both ends may be the same, or may be different according to requirements.

[0088] In one example of this embodiment, the insulating protrusion can span the front of the positive substrate and / or the negative substrate to increase the contact area between the insulating isolation belt and the positive substrate and / or the negative substrate, and the contact area between the insulating isolation belt and the inner wall of the wall, so that the mechanical force applied to the insulating isolation belt is partially transmitted to the positive substrate and / or the negative substrate and the wall, thereby further improving the strength of the insulating isolation belt, and thus improving the overall strength and reliability of the LED bracket as a whole. At the same time, it can also improve the airtightness of the LED bracket, thereby improving the moisture-proof performance of the LED bracket.

[0089] In one example of this embodiment, the functional areas of the positive electrode substrate and the negative electrode substrate are located at the bottom of the reflective cavity formed by the wall body. Optionally, the insulating protrusions provided on the insulating isolation belt are in direct contact with the inner side surface of the reflective cavity, and the height of the insulating protrusions is less than the height of the inner side surface of the reflective cavity; so that the mechanical force exerted on the insulating isolation belt is partially transmitted to the wall body, thereby further improving the strength of the insulating isolation belt, and thus improving the overall strength and reliability of the LED bracket as a whole. At the same time, the airtightness of the LED bracket can also be improved, thereby improving the moisture-proof performance of the LED bracket.

[0090] It should be understood that, optionally, the insulating protrusions provided on the insulating isolation belt can also be arranged to contact at least one substrate and the surrounding wall at the same time, so that the mechanical force applied to the insulating isolation belt is partially transmitted to the surrounding wall and at least one substrate, thereby maximizing the overall strength, reliability and moisture-proof performance of the LED bracket.

[0091] In an example of this implementation, in order to further improve the strength of the insulating isolation zone, the front side of the insulating isolation zone can be set higher than the front sides of the positive substrate and the negative substrate, and the specific height can be flexibly set according to demand.

[0092] In an example of this embodiment, the insulating protrusions provided on the insulating isolation belt can be integrally formed with the insulating isolation belt, or can be formed separately, and the specific configuration can be flexibly set according to specific processes and requirements.

[0093] In one example of this embodiment, the insulating protrusions provided on the insulating isolation belt may be made of the same material as the insulating isolation belt, and of course in some examples they may also be different.

[0094] The specific shape and structure of the insulating protrusion in this embodiment can be flexibly set, for example, it can be set to a hemispherical shape, or a semicircular pancake shape, etc., of course, it can also be less than half or more than half of a sphere or a pancake shape; in this case, the profile of the longitudinal section of the insulating protrusion along the height direction can be an arc profile, or the profile of the longitudinal section of the insulating protrusion along the height direction is a profile composed of an upper horizontal side, a lower horizontal side, and an arc between the upper horizontal side and the lower horizontal side. Of course, the insulating protrusion in this embodiment can also be set to a square or other regular shape, and of course it can also be set to an irregular shape, which can be flexibly set according to the specific application scenario.

[0095] In this embodiment, an insulating protrusion is provided on at least one end of the front side of the insulating isolation belt, and the insulating protrusion can be in contact with at least one substrate or surrounding wall at the same time, which not only increases the material weight of the insulating isolation belt, and thus increases the overall weight occupied by the insulating isolation belt in the bracket, thereby improving the overall strength of the insulating isolation belt, but also allows the mechanical force exerted on the insulating isolation belt to be partially transmitted to the surrounding wall and at least one substrate, thereby maximizing the overall strength, reliability and moisture-proof performance of the LED bracket; at the same time, the contact area between the insulating isolation belt and the substrate and the surrounding wall is increased, thereby improving the airtightness of the bracket.

[0096] In this embodiment, the functional area and the wall contact area of ​​at least one of the positive and negative substrates of the LED bracket are not on the same plane, for example, the functional area and the wall contact area on the front of the positive substrate are not on the same plane, and / or, the functional area and the wall contact area on the front of the negative substrate are not on the same plane; the specific setting of one or two functional areas and the wall contact areas of the positive and negative substrates are not on the same plane can be flexibly set according to specific needs. For example, in one example, in order to comprehensively improve the sealing of the LED bracket, the functional areas and the wall contact areas of the positive and negative substrates can be set not to be on the same plane. This setting can extend the path between the functional areas of the wall contact area of ​​the substrate, that is, extend the path for moisture to enter the functional area, thereby improving the sealing performance of the LED bracket and the LED made using the LED bracket, improving the reliability and durability of the LED, so that the LED can better meet the use requirements of various environments, and is more conducive to the promotion and use of LEDs.

[0097] In an example of this embodiment, the wall contact area on the front side of the substrate may be directly connected to the functional area, and the wall contact area may be an inclined surface, a curved surface or other types of surfaces.

[0098] In another example of this embodiment, in order to further extend the path between the wall contact area of ​​the substrate and the functional area, a connecting transition area may be provided between the wall contact area of ​​the substrate and the functional area, so that moisture needs to pass through the wall contact area and the connecting transition area before entering the functional area, which can further improve the moisture-proof performance of the bracket. In this embodiment, the connecting transition area may also be an inclined surface, an arc surface, or a combined surface, and the combined surface may also include but is not limited to a combination of at least two of a plane, an inclined surface, and an arc surface.

[0099] In this embodiment, the functional area and the wall contact area of ​​at least one of the positive substrate and the negative substrate of the LED bracket are not on the same plane, and optionally, the plane where the functional area is located can be set higher than the plane where the wall contact area is located, or the plane where the functional area is located can be set lower than the plane where the wall contact area is located. Therefore, the path between the wall contact area and the functional area of ​​the substrate can be extended, that is, the path for moisture to enter the functional area can be extended, thereby improving the moisture-proof performance of the LED bracket and the LED made using the LED bracket.

[0100] Embodiment 2:

[0101] For ease of understanding, this embodiment is described below using several examples of the arrangement of insulating protrusions on insulating isolation bands.

[0102] See also Figure 2-1 As shown, 20 is a wall, 21 is a positive electrode substrate, 22 is a negative electrode substrate, 23 is an insulating isolation zone, 231 is an insulating protrusion, Figure 2-1 In the LED bracket shown, an insulating protrusion 231 is provided at the left end of the insulating isolation belt 23. The insulating protrusion 231 may be hemispherical or semicircular, and the insulating protrusion 231 spans the positive substrate and the negative substrate, and may optionally contact the surrounding wall 20 at the same time; in one example, the insulating protrusion 231, the insulating isolation belt 23 and the surrounding wall 20 may be formed by the same process or by different processes, and in one example, the three may be integrally formed, for example, by injection molding. The insulating protrusion 231 is in contact with the positive substrate 21, the negative substrate 22 and the surrounding wall 20 at the same time, so that the mechanical force exerted on the insulating isolation belt is partially transmitted to the surrounding wall and at least one substrate, thereby maximizing the overall strength, reliability and moisture resistance of the LED bracket, and increasing the contact area with the substrate and the surrounding wall 20, thereby improving the airtightness of the LED bracket.

[0103] It should be understood that in some embodiments, the insulating protrusion 231 may be located only on one of the substrates, for example, Figure 2-2 As shown, insulating protrusions 231 are provided at both ends of the insulating isolation belt 23, and the shapes and sizes of the insulating protrusions 231 can be the same, and of course they can be set to be different according to needs. The insulating protrusions 231 are only located on the positive substrate 21, and of course the insulating protrusions 231 at one end can be located on the positive substrate 21, and the insulating protrusions 231 at the other end can be located on the negative substrate 22. The insulating protrusions 231 can contact the surrounding wall 20 at the same time, so that the mechanical force on the insulating isolation belt is partially transmitted to the surrounding wall and the positive substrate, thereby improving the overall strength, reliability and moisture-proof performance of the LED bracket, and increasing the contact area with the substrate and the surrounding wall 20, thereby improving the airtightness of the LED bracket.

[0104] For example, see Figure 2-3 As shown, it is Figure 2-2 Compared with the LED bracket shown in the figure, the difference is that both ends of the insulating isolation belt 23 are provided with insulating protrusions 231, and the insulating protrusions 231 have the same shape and size, and the insulating protrusions 231 span the positive substrate 21 and the negative substrate 22. The insulating protrusions 231 can contact the surrounding wall 20 at the same time, so that the mechanical force exerted on the insulating isolation belt is partially transmitted to the surrounding wall, the positive substrate and the negative substrate, thereby improving the overall strength, reliability and moisture-proof performance of the LED bracket, and increasing the contact area with the positive substrate 21, the negative substrate 22 and the surrounding wall 20, thereby improving the airtightness of the LED bracket.

[0105] For example, see Figure 2-4 As shown, it is Figure 2-3 Compared with the LED bracket shown in the figure, the difference is that both ends of the insulating isolation belt 23 are provided with insulating protrusions 231, and the insulating protrusions 231 are all protrusion structures with a rectangular cross section, and the insulating protrusions 231 span the positive substrate 21 and the negative substrate 22. The insulating protrusions 231 can contact the surrounding wall 20 at the same time, so that the mechanical force exerted on the insulating isolation belt is partially transmitted to the surrounding wall, the positive substrate and the negative substrate, thereby improving the overall strength, reliability and moisture-proof performance of the LED bracket.

[0106] For example, see Figure 2-5 As shown, it is Figure 2-3 Compared with the LED bracket shown in the figure, the difference is that both ends of the insulating isolation belt 23 are provided with insulating protrusions 231, and the insulating protrusions 231 are arc-shaped surfaces with non-semicircular cross-sections, and the insulating protrusions 231 also span the positive substrate 21 and the negative substrate 22. The insulating protrusions 231 can contact the surrounding wall 20 at the same time, so that the mechanical force exerted on the insulating isolation belt is partially transmitted to the surrounding wall, the positive substrate and the negative substrate, thereby improving the overall strength, reliability and moisture resistance of the LED bracket; in addition, it should be understood that in this embodiment, under the premise of meeting the light output efficiency of the LED bracket, the insulating protrusions can be extended as much as possible in the height, width and length directions to maximize the strength and moisture resistance. For example, see Figure 2-6 As shown, the insulating protrusion 231 extends as long as possible in the length direction toward the positive electrode substrate 21, so that the contact area between the insulating protrusion and the surrounding wall 20 and the substrate is increased.

[0107] In other embodiments of this embodiment, the insulating protrusion 231 may also be an irregular shape. For example, one example of the insulating protrusion 231 is an irregular shaped protrusion, which also spans the positive substrate 21 and the negative substrate 22. The insulating protrusion 231 can contact the surrounding wall 20 at the same time, so that the mechanical force exerted on the insulating isolation belt is partially transmitted to the surrounding wall, the positive substrate and the negative substrate, thereby improving the overall strength, reliability and moisture resistance of the LED bracket.

[0108] In other embodiments of this embodiment, when insulating protrusions 231 are provided at both ends of the insulating isolation zone 23, the shapes and sizes of the insulating protrusions 231 at the two ends may also be different. Figure 2-8 As shown, the insulating protrusion 231 arranged at the left end of the insulating isolation zone is in the shape of a semi-sphere or a semi-circular pancake, and the insulating protrusion arranged at the right end is in the shape of a hexahedron.

[0109] It can be seen that the insulating protrusion provided on at least one end of the front side of the insulating isolation belt provided in this embodiment can contact at least one substrate or surrounding wall at the same time, which can not only increase the overall weight occupied by the insulating isolation belt in the bracket and improve the overall strength of the insulating isolation belt, but also make the mechanical force exerted on the insulating isolation belt partially transferred to the surrounding wall and at least one substrate, thereby maximizing the overall strength, reliability and moisture-proof performance of the LED bracket.

[0110] Embodiment three:

[0111] See also Figure 1-1 to Figure 1-2 As shown, in the existing LED bracket, the insulating isolation zone between the positive substrate and the negative substrate is perpendicular to the long side of the bracket, arranged parallel to the positive substrate and the negative substrate, and parallel to the positive substrate and the negative substrate; and the insulating isolation zone is made of a relatively fragile insulating material, and the width of the insulating isolation zone is narrow, which makes the insulating isolation zone prone to breakage, reducing the overall strength and reliability of the LED bracket.

[0112] To address this problem, the present embodiment further provides an LED bracket with a novel structure, in which the two relatively long sides of the cross-sectional profile of the insulating isolation belt of the LED bracket are arc-shaped sides, or are curved sides with at least one bend, or are folded line sides with at least one bend, or are hypotenuses with an angle greater than or equal to 10° and less than 90° with the short side of the negative substrate. In this way, when the isolation belt is subjected to force, part of the mechanical force can be transferred to the positive substrate, the negative substrate and the surrounding wall, thereby increasing the strength of the insulating isolation belt.

[0113] Optionally, the two relatively long sides of the cross-sectional profile of the insulating isolation zone in this embodiment can be parallel or non-parallel, which can be flexibly set according to needs; for ease of understanding, this embodiment is explained below with two examples of parallel setting and non-parallel setting respectively.

[0114] Example of parallel setup:

[0115] See also Figure 3-1 As shown, 30 is a wall, 31 is a positive electrode substrate, 32 is a negative electrode substrate, and 33 is an insulating isolation area. Figure 3-1 In FIG. 1 , the dotted line is the short side of the negative electrode substrate 32. Figure 3-1 In the cross-sectional profile of the insulating isolation zone 33, the two long sides opposite to each other are the oblique sides with an angle of greater than or equal to 10° and less than 90° with the short side of the negative electrode substrate, that is, Figure 3-1 The angle A in the insulating isolation zone is greater than or equal to 10° and less than 90°. The value of the angle can be flexibly set according to at least one of the strength requirements of the specific application scenario, the material used for the insulating isolation zone, the formation process, etc. For example, in one example, the value of the angle A can be 75° to 85°, such as specific values ​​of 75°, 78°, 80°, 83°, 85°, etc., so that when the insulating isolation zone 33 is subjected to mechanical force, part of the mechanical force can be transferred to the positive substrate 31, the negative substrate 32 and the surrounding wall 30, thereby improving the strength of the insulating isolation zone 33, and then improving the overall strength and reliability of the LED bracket.

[0116] In this embodiment, the two long sides of the cross-sectional profile of the insulating isolation zone 33 can be curved sides in addition to the oblique sides. For example, one configuration is shown in FIG. Figure 3-2 As shown, the two relatively long sides of the cross-sectional profile of the insulating isolation zone 33 are two arc-shaped sides parallel to each other. The setting of the arc-shaped sides can also enable the insulating isolation zone 33 to transfer a part of the mechanical force received to the positive substrate 31, the negative substrate 32 and the surrounding wall 30 when subjected to mechanical force, thereby improving the strength of the insulating isolation zone 33.

[0117] In this embodiment, the two long sides of the cross-sectional profile of the insulating isolation zone 33 can be curved sides in addition to the oblique sides and the arc sides. For example, one configuration is shown in FIG. Figure 3-3 As shown in the figure, the two long sides of the cross-sectional profile of the insulating isolation belt 33 are two parallel curved sides. The setting of the curved sides can also make the insulating isolation belt 33 transfer part of the mechanical force to the positive substrate 31, the negative substrate 32 and the surrounding wall 30 when it is subjected to mechanical force, thereby improving the strength of the insulating isolation belt 33. In addition to the number of bends, the curved sides in this embodiment can be flexibly set. For example, Figure 3-3 In addition to the curve edges shown, Figure 3-5 The curved edges shown may of course also be curved edges of other forms.

[0118] In this embodiment, the two long sides of the cross-sectional profile of the insulating isolation zone 33 can be not only be inclined sides, arc sides and curved sides, but also be folded lines with at least one bend. Figure 3-4 As shown, the two long sides of the cross-sectional profile of the insulating isolation belt 33 are two parallel fold lines. The fold lines can also be set so that when the insulating isolation belt 33 is subjected to mechanical force, part of the mechanical force is transferred to the positive electrode substrate 31, the negative electrode substrate 32 and the surrounding wall 30, thereby improving the strength of the insulating isolation belt 33. In addition to the number of bends, the fold lines in this embodiment can be flexibly set. For example, Figure 3-4 In addition to the polyline edges shown, Figure 3-6 The fold line edges shown may of course also be fold line edges of other forms.

[0119] Example of a non-parallel setup:

[0120] See also Figure 4-1 As shown, 40 is a wall, 41 is a positive electrode substrate, 42 is a negative electrode substrate, and 43 is an insulating isolation area. Figure 4-1 In the figure, the two relatively long sides of the cross-sectional profile of the insulating isolation belt 43 are hypotenuses with an angle greater than or equal to 10° and less than 90° with the short side of the negative substrate, and the two hypotenuses are not parallel. In this way, when the insulating isolation belt 43 is subjected to mechanical force, part of the mechanical force can be transferred to the positive substrate 41, the negative substrate 42 and the surrounding wall 40, thereby improving the strength of the insulating isolation belt 43, and then improving the overall strength and reliability of the LED bracket.

[0121] In this embodiment, the two long sides of the cross-sectional profile of the insulating isolation zone 43 can be curved sides in addition to the oblique sides. For example, one configuration is shown in FIG. Figure 4-2 As shown, the two relatively long sides of the cross-sectional profile of the insulating isolation zone 43 are two non-parallel arcuate sides. The setting of the non-parallel arcuate sides can also enable the insulating isolation zone 43 to transfer a part of the mechanical force received to the positive substrate 41, the negative substrate 42 and the surrounding wall 40 when subjected to mechanical force, thereby improving the strength of the insulating isolation zone 43.

[0122] In this embodiment, the two long sides of the cross-sectional profile of the insulating isolation zone 43 can be curved sides in addition to the oblique sides and the arc sides. For example, one configuration is shown in FIG. Figure 4-3 As shown, the two relatively long sides of the cross-sectional profile of the insulating isolation belt 43 are two non-parallel curved sides. The setting of the two non-parallel curved sides can also enable the insulating isolation belt 43 to transfer a part of the mechanical force received to the positive substrate 41, the negative substrate 42 and the surrounding wall 40 when subjected to mechanical force, thereby improving the strength of the insulating isolation belt 43.

[0123] In this embodiment, the two long sides of the cross-sectional profile of the insulating isolation zone 43 can be not only be inclined sides, arc sides and curved sides, but also be folded lines with at least one bend. Figure 4-4As shown, the two relatively long sides of the cross-sectional profile of the insulating isolation belt 43 are two non-parallel fold line sides. The setting of the two non-parallel fold line sides can also enable the insulating isolation belt 43 to transfer a part of the mechanical force received to the positive substrate 41, the negative substrate 42 and the surrounding wall 40 when subjected to mechanical force, thereby improving the strength of the insulating isolation belt 43.

[0124] In this embodiment, the two relatively long sides of the cross-sectional profile of the insulating isolation belt are set as arc sides, or curved sides, or broken line sides, or as oblique sides with an angle greater than or equal to 10° and less than 90° with the short side of the negative substrate. When the isolation belt is subjected to force, part of the mechanical force can be transferred to the positive substrate and / or the negative substrate, thereby increasing the strength of the insulating isolation belt and improving the overall strength and reliability of the LED bracket and the LED made using the bracket.

[0125] Embodiment 4:

[0126] It should be understood that the present embodiment can also combine the insulating isolation belt in the above-mentioned embodiment 3 with the insulating protrusion structure in the above-mentioned embodiment 1 or 2 to double increase the strength of the insulating isolation belt, thereby improving the overall strength of the LED bracket, and can also simultaneously increase the contact area between the insulating isolation belt and the substrate and / or the surrounding wall, thereby improving the moisture-proof performance of the LED bracket. For ease of understanding, the present embodiment is still described below using two examples of parallel and non-parallel settings of the insulating isolation belt combined with the insulating protrusion.

[0127] Example of parallel setup + insulating protrusions:

[0128] See also Figure 5-1 As shown, 50 is a wall, 51 is a positive electrode substrate, 52 is a negative electrode substrate, 53 is an insulating isolation area, and 532 is an insulating protrusion. Figure 5-1 in Figure 5-1 In the figure, the two opposite long sides of the cross-sectional profile of the insulating isolation belt 53 are two parallel oblique sides with an angle greater than 0° and less than or equal to 45° with the horizontal line on the front side of the positive substrate. In this way, when the insulating isolation belt 53 is subjected to mechanical force, part of the mechanical force can be transferred to the positive substrate 51, the negative substrate 52 and the surrounding wall 50, thereby improving the strength of the insulating isolation belt 53, and then improving the overall strength and reliability of the LED bracket; at the same time, insulating protrusions 531 are provided at both ends of the insulating isolation belt 53, and the insulating protrusions 531 span the positive substrate 51 and the negative substrate 52; and optionally, the insulating protrusions 531 can contact the surrounding wall 50 at the same time, so that part of the mechanical force received by the insulating isolation belt 53 is transferred to the surrounding wall 50, the positive substrate 51 and the negative substrate 52, further improving the overall strength, reliability and moisture-proof performance of the LED bracket, and increasing the contact area with the substrate and the surrounding wall 50, and further improving the airtightness of the LED bracket.

[0129] In this embodiment, the two long sides of the cross-sectional profile of the insulating isolation zone 53 can be curved sides in addition to the oblique sides. For example, one configuration is shown in FIG. Figure 5-2 As shown, the two long sides of the cross-sectional profile of the insulating isolation belt 53 are two arc-shaped sides parallel to each other. The setting of the arc-shaped sides can also make the insulating isolation belt 53 transfer part of the mechanical force to the positive substrate 51, the negative substrate 52 and the surrounding wall 50 when it is subjected to mechanical force, thereby improving the strength of the insulating isolation belt 53. At the same time, insulating protrusions 531 are also provided at both ends of the insulating isolation belt 53, and the insulating protrusions 531 span the positive substrate 51 and the negative substrate 52; and the insulating protrusions 531 are optionally in contact with the surrounding wall 50, so that the mechanical force received by the insulating isolation belt 53 is partially transferred to the surrounding wall 50, the positive substrate 51 and the negative substrate 52, further improving the overall strength, reliability and moisture-proof performance of the LED bracket, and increasing the contact area with the substrate and the surrounding wall 50, and further improving the airtightness of the LED bracket.

[0130] In this embodiment, the two long sides of the cross-sectional profile of the insulating isolation zone 53 can be curved sides in addition to the oblique sides and the arc sides. For example, one configuration is shown in FIG. Figure 5-3 As shown, the two long sides of the cross-sectional profile of the insulating isolation belt 53 are two curved sides parallel to each other. The setting of the curved sides can also make the insulating isolation belt 53 transfer part of the mechanical force to the positive substrate 51, the negative substrate 52 and the surrounding wall 50 when it is subjected to mechanical force, thereby improving the strength of the insulating isolation belt 53. At the same time, insulating protrusions 531 are also provided at both ends of the insulating isolation belt 53, and the insulating protrusions 531 span the positive substrate 51 and the negative substrate 52; and the insulating protrusions 531 are in contact with the surrounding wall 50, so that the mechanical force of the insulating isolation belt 53 is partially transferred to the surrounding wall 50, the positive substrate 51 and the negative substrate 52, further improving the overall strength, reliability and moisture-proof performance of the LED bracket.

[0131] In this embodiment, the two long sides of the cross-sectional profile of the insulating isolation zone 53 can be not only beveled sides, arc-shaped sides, and curved sides, but also be folded lines with at least one bend. Figure 5-4As shown, the two long sides of the cross-sectional profile of the insulating isolation belt 53 are two parallel fold lines. The setting of the fold lines can also make the insulating isolation belt 53 transfer part of the mechanical force to the positive substrate 51, the negative substrate 52 and the surrounding wall 50 when it is subjected to mechanical force, thereby improving the strength of the insulating isolation belt 53. At the same time, insulating protrusions 531 are also provided at both ends of the insulating isolation belt 53, and the insulating protrusions 531 span the positive substrate 51 and the negative substrate 52; and the insulating protrusions 531 are in contact with the surrounding wall 50, so that the mechanical force received by the insulating isolation belt 53 is partially transferred to the surrounding wall 50, the positive substrate 51 and the negative substrate 52, further improving the overall strength, reliability and moisture-proof performance of the LED bracket, and increasing the contact area with the substrate and the surrounding wall 50, and further improving the airtightness of the LED bracket.

[0132] Example of a non-parallel setup:

[0133] See also Figure 6-1 As shown, 60 is a wall, 61 is a positive electrode substrate, 62 is a negative electrode substrate, 63 is an insulating isolation area, and 631 is an insulating protrusion. Figure 6-1 In the figure, the two long sides of the cross-sectional profile of the insulating isolation belt 63 are two oblique sides whose angle with the horizontal line on the front side of the positive substrate is greater than 0° and less than or equal to 45°, and the two oblique sides are not parallel to each other, so that when the insulating isolation belt 63 is subjected to mechanical force, part of the mechanical force can be transmitted to the positive substrate 61 and the negative substrate 62, thereby improving the strength of the insulating isolation belt 63, and then improving the overall strength and reliability of the LED bracket; at the same time, insulating protrusions 631 are also provided at both ends of the insulating isolation belt 63, and the insulating protrusions 631 span the positive substrate 61 and the negative substrate 62; and the insulating protrusions 631 are in contact with the surrounding wall 60, so that part of the mechanical force received by the insulating isolation belt 63 is transmitted to the surrounding wall 60, the positive substrate 61 and the negative substrate 62, further improving the overall strength, reliability and moisture-proof performance of the LED bracket, and increasing the contact area with the substrate and the surrounding wall 60, and further improving the airtightness of the LED bracket.

[0134] In this embodiment, the two long sides of the cross-sectional profile of the insulating isolation zone 63 can be curved sides in addition to the oblique sides. For example, one configuration is shown in FIG. Figure 6-2As shown, the two relatively long sides of the cross-sectional profile of the insulating isolation belt 63 are two non-parallel arc-shaped sides. The setting of the non-parallel arc-shaped sides can also make the insulating isolation belt 63 transfer part of the mechanical force to the positive substrate 61 and the negative substrate 62 when it is subjected to mechanical force, thereby improving the strength of the insulating isolation belt 63. At the same time, insulating protrusions 631 are also provided at both ends of the insulating isolation belt 63. The insulating protrusions 631 span the positive substrate 61 and the negative substrate 62; and the insulating protrusions 631 are in contact with the surrounding wall 60, so that part of the mechanical force applied to the insulating isolation belt 63 is transferred to the surrounding wall 60, the positive substrate 61 and the negative substrate 62, thereby further improving the overall strength, reliability and moisture-proof performance of the LED bracket, and increasing the contact area with the substrate and the surrounding wall 60, thereby further improving the airtightness of the LED bracket.

[0135] In this embodiment, the two long sides of the cross-sectional profile of the insulating isolation zone 63 can be curved sides in addition to the oblique sides and the arc sides. For example, one configuration is shown in FIG. Figure 6-3 As shown, the two long sides of the cross-sectional profile of the insulating isolation belt 63 are two non-parallel curved sides. The setting of the two non-parallel curved sides can also make the insulating isolation belt 63 transfer part of the mechanical force to the positive substrate 61 and the negative substrate 62 when it is subjected to mechanical force, thereby improving the strength of the insulating isolation belt 63; at the same time, insulating protrusions 631 are also provided at both ends of the insulating isolation belt 63, and the insulating protrusions 631 span the positive substrate 61 and the negative substrate 62; and the insulating protrusions 631 are in contact with the surrounding wall 60, so that part of the mechanical force applied to the insulating isolation belt 63 is transferred to the surrounding wall 60, the positive substrate 61 and the negative substrate 62, thereby further improving the overall strength, reliability and moisture-proof performance of the LED bracket, and increasing the contact area with the substrate and the surrounding wall 60, thereby further improving the airtightness of the LED bracket.

[0136] In this embodiment, the two long sides of the cross-sectional profile of the insulating isolation zone 63 can be not only beveled sides, arc-shaped sides, and curved sides, but also be folded lines with at least one bend. Figure 6-4As shown, the two relatively long sides of the cross-sectional profile of the insulating isolation belt 63 are two non-parallel fold line sides. The setting of the two non-parallel fold line sides can also make the insulating isolation belt 63, when subjected to mechanical force, transfer part of the mechanical force to the positive substrate 61 and the negative substrate 62, thereby improving the strength of the insulating isolation belt 63; at the same time, insulating protrusions 631 are also provided at both ends of the insulating isolation belt 63, and the insulating protrusions 631 span the positive substrate 61 and the negative substrate 62; and the insulating protrusions 631 are in contact with the surrounding wall 60, so that part of the mechanical force received by the insulating isolation belt 63 is transferred to the surrounding wall 60, the positive substrate 61 and the negative substrate 62, thereby further improving the overall strength, reliability and moisture-proof performance of the LED bracket, and increasing the contact area with the substrate and the surrounding wall 60, thereby further improving the airtightness of the LED bracket.

[0137] In this embodiment, the two long sides of the cross-sectional profile of the insulating isolation belt are set to arc sides, or curved sides, or broken line sides, or hypotenuses with an angle greater than 0° and less than or equal to 64° with the horizontal line on the front side of the positive substrate. At the same time, insulating protrusions are also provided at both ends of the insulating isolation belt, and the insulating protrusions span the positive substrate and the negative substrate; and the insulating protrusions are in contact with the surrounding wall; thereby, the mechanical force exerted on the insulating isolation belt is partially transmitted to the surrounding wall, the positive substrate and the negative substrate, thereby further improving the overall strength, reliability and moisture-proof performance of the LED bracket, and increasing the contact area with the substrate and the surrounding wall, thereby further improving the airtightness of the LED bracket.

[0138] Embodiment five:

[0139] For ease of understanding, this embodiment is described by taking an example in which the wall contact area on the substrate is directly connected to the functional area, and the functional area is located above the wall contact area.

[0140] exist Figure 7-1 to Figure 7-4 In the figure, 70 is a wall body, 71 is a substrate (which may be a positive electrode substrate and / or a negative electrode substrate), 711 is a functional area, and 712 is a wall contact area; 731 is an insulating protrusion set at both ends of the insulating isolation zone. It should be understood that the specific setting method of the insulating protrusion can refer to the methods shown in the above embodiments, and is not limited to the method shown in the figure of this embodiment.

[0141] See also Figure 7-1 As shown in the figure, the schematic diagram of the direct connection between the wall contact area and the functional area on the substrate is shown. Figure 7-1In the embodiment, the wall contact area 712 is an inclined surface, and the functional area 711 is a plane located in the wall contact area 712. Of course, the functional area 711 can also be set as a non-plane according to needs. The path between the wall contact area 712 and the functional area 711 is significantly longer than the path in the existing wall contact area and the functional area are set on the same plane, so the path for moisture to enter the functional area can be lengthened, thereby improving the moisture-proof performance of the bracket and improving the reliability of LED lamp beads or other products made using the bracket.

[0142] In some examples, the wall contact area 712 may not be a slope, but other types of surfaces. Figure 7-2 As shown in the figure, the wall contact area 712 is a curved surface, and the curved surface is a convex curved surface protruding toward the outside of the substrate 71. Figure 7-2 The arrangement of the convex curved surface shown is relative to Figure 7-1 The inclined surface shown can further extend the path for moisture to enter the functional area, thereby further improving the moisture-proof effect.

[0143] In some examples, when the wall contact area 712 is a curved surface, in addition to Figure 7-2 In addition to the convex curved surface shown, other types of curved surfaces may also be used. Figure 7-3 As shown, it is an inner arc surface concave toward the inner side of the substrate 71, which is relative to Figure 7-1 The inclined surface shown can also further extend the path for moisture to enter the functional area, thereby further improving the moisture-proof effect.

[0144] Of course, it should be understood that in this embodiment, the wall contact area 712 can be a slope or a curved surface, and can also be set as other types of surfaces according to needs, and can be a regular surface or an irregular surface. Figure 7-4 As shown, the wall contact area 712 is a curved surface, which is relative to Figure 7-1 The inclined surface shown can also further extend the path for moisture to enter the functional area, thereby further improving the moisture-proof effect.

[0145] In addition, it should be understood that Figure 7-1 to Figure 7-4 The wall contact areas 712 on the two opposite sides can be set to the same surface or different surfaces, which can be flexibly set according to the application scenario.

[0146] In some examples, the formation process of the above-mentioned wall contact area 712 can be flexibly selected, such as including but not limited to etching and cutting. The formation method is simple, low-cost and efficient, and can improve the moisture-proof performance of the LED bracket while ensuring the manufacturing cost and efficiency of the bracket.

[0147] Embodiment six:

[0148] For ease of understanding, this embodiment is described by taking an example in which a connecting transition zone is provided between the wall contact zone and the functional zone on the substrate, and the functional zone is located above the wall contact zone.

[0149] Optionally, in this embodiment, the plane where the functional area is located may be higher than the plane where the wall contact area is located, and the specific height difference between the two can be flexibly set according to the application scenario. For example, the height difference between the plane where the functional area is located and the plane where the wall contact area is located can be set to be greater than 0 and less than or equal to one-fourth of the depth of the reflection cavity; of course, it can also be set to other values ​​according to specific needs, for example, the height difference can be set to be greater than 0 and less than or equal to one-fifth, one-sixth or one-third of the depth of the reflection cavity, etc.

[0150] Optionally, in this embodiment, the connection transition zone between the wall contact area and the functional area may also be in contact with the wall body in at least a portion of its area, thereby increasing the contact area between the substrate and the wall body, improving the strength of the bracket, and further extending the path for moisture to enter the functional area.

[0151] The wall contact area and the connection transition area in this embodiment can be located on the same plane or on different planes, and the types of the two can be the same or different. It should be understood that the wall contact area in this embodiment can also be several types of surfaces shown in the second embodiment.

[0152] exist Figure 8-1 to Figure 8-8 In the figure, 80 is a wall body, 81 is a substrate (which may be a positive electrode substrate and / or a negative electrode substrate), 811 is a functional area, and 812 is a wall contact area; 831 is an insulating protrusion arranged at both ends of the insulating isolation zone. It should be understood that the specific arrangement of the insulating protrusion can refer to the methods shown in the above embodiments, and is not limited to the methods shown in the figures of this embodiment.

[0153] For example, in one example, see Figure 8-1 As shown, the area of ​​the wall contact area 812 is the inclined area where the front of the substrate directly contacts the wall body 80, and the connecting transition area 813 is the inclined area where the front of the substrate does not contact the wall body 80. The connecting transition area 813 and the wall contact area 812 form an inclined surface, that is, the two are located on the same surface. The setting of the connecting transition area 813 can further increase the path between the wall contact area 812 and the functional area 811, thereby improving the moisture-proof performance of the bracket.

[0154] For example, in one example, see Figure 8-2 As shown, the area of ​​the wall contact area 812 is the plane area where the front surface of the substrate directly contacts the wall body 80, and the connecting transition area 813 is the inclined area where the front surface of the substrate connects the wall contact area 812 and the functional area 811. Figure 8-2In the example shown, a portion of the connecting transition area 813 is also in direct contact with the wall body 80. Therefore, while further increasing the path between the wall contact area 812 and the functional area 811, the strength of the bracket can also be improved, that is, the moisture resistance and strength of the bracket can be improved at the same time.

[0155] For example, in one example, see Figure 8-3 As shown, the area of ​​the wall contact area 812 is a plane area where the front side of the substrate directly contacts the wall body 80, and the connecting transition area 813 is an arc surface area where the front side of the substrate connects the wall contact area 812 and the functional area 811, and the arc surface area is a convex arc surface area protruding toward the outside of the substrate 81; Figure 8-3 In the example shown, a portion of the connection transition area 813 is also in direct contact with the wall body 80, so the path between the wall contact area 812 and the functional area 811 can be further increased to improve the moisture-proof performance while improving the strength of the bracket. Of course, in this embodiment, the connection transition area 813 can be a concave arc surface that is concave toward the inner side of the substrate 81, in addition to a convex arc surface, for example, see Figure 8-4 As shown in the figure, an example connection transition area 813 is a concave arc surface, which can further increase the path between the wall contact area 812 and the functional area 811 to improve the moisture-proof performance while improving the strength of the bracket.

[0156] In addition, it should be understood that the connection transition areas 813 on opposite sides of the front surface of the substrate in this embodiment can also be set as the same type of surface, or set as different types of surfaces. Figure 8-5 As shown, the connection transition zone 813 on one side of the substrate is set as a convex arc surface, and the connection transition zone 813 on the other side is set as a concave arc surface. The specific setting method can be flexibly determined according to the specific application scenario and the adopted process.

[0157] In this embodiment, the connecting transition area may also be a combined surface, and the combined surface may include but is not limited to a combination of at least two of a plane, an inclined surface, and an arc surface.

[0158] For example, see Figure 8-6 As shown, the area of ​​the wall contact area 812 is a plane area where the front surface of the substrate directly contacts the wall body 80, and the connecting transition area 813 is a combined surface of the inclined surface and the arc surface connecting the wall contact area 812 and the functional area 811 on the front surface of the substrate; for another example, see Figure 8-7 As shown, it is Figure 8-6 The difference between the bracket shown is that the connecting transition area 813 is composed of two inclined surfaces and a plane connecting the two inclined surfaces; for example, see Figure 8-8 As shown, it is Figure 8-6 and Figure 8-7The difference between the brackets shown is that the connection transition zone 813 is composed of a combination of an inclined surface, a plane and an arc surface connected in sequence. It can be seen that when the connection transition zone 813 in this embodiment is a combination surface, the specific combination method can be flexibly set. It should be understood that the wall contact area 812 in this embodiment can also be a combination surface, and can be a combination surface of the same type as the connection transition zone 813, or a combination surface of a different type from the connection transition zone 813.

[0159] In this embodiment, a connecting transition area is further set between the wall contact area and the functional area on the substrate, which can further increase the path between the wall contact area 812 and the functional area 811 to improve the moisture-proof performance; and optionally, at least a portion of the connecting transition area can be set to contact the wall body to simultaneously increase the contact area between the substrate and the wall body, thereby improving the strength of the bracket.

[0160] Embodiment seven:

[0161] For ease of understanding, this embodiment is described by taking an example in which a connecting transition zone is provided between the wall contact zone and the functional zone on the substrate, and the functional zone is located below the wall contact zone.

[0162] In an example of this embodiment, it can be arranged that the planes where the functional areas of the positive electrode substrate and the negative electrode substrate are located are both lower than the plane where the contact area of ​​the wall is located.

[0163] In an example of this embodiment, the functional areas of the positive substrate and the negative substrate are located at the bottom of the reflection cavity formed by the wall; the height difference between the plane where the functional area is located and the plane where the wall contact area is located can be flexibly set, for example, the height difference can be set to be greater than 0 and less than or equal to one-fourth of the depth of the reflection cavity; of course, it can also be set to other values ​​according to specific needs, for example, the height difference can be set to be greater than 0 and less than or equal to one-fifth, one-sixth or one-third of the depth of the reflection cavity, etc.

[0164] In this embodiment, the connection transition area may be an inclined surface, an arcuate surface, or a combined surface, and the combined surface is a combination of at least two of a plane, an inclined surface, and an arcuate surface.

[0165] Optionally, at least a portion of the connection transition zone may also be in contact with the surrounding wall, so as to simultaneously increase the contact area between the substrate and the surrounding wall, thereby increasing the strength of the bracket.

[0166] The wall contact area and the connection transition area in this embodiment may be of the same type and / or formed using the same or different processes. It should be understood that the wall contact area in this embodiment may also be a surface of several types as shown in the second embodiment.

[0167] exist Figure 9-1In Figure 9-9, 90 is the wall body, 91 is the substrate (which may be a positive substrate and / or a negative substrate), 911 is the functional area, and 912 is the wall contact area; 931 is the insulating protrusions set at both ends of the insulating isolation zone. It should be understood that the specific setting method of the insulating protrusions can refer to the methods shown in the above-mentioned embodiments, and is not limited to the methods shown in the figures of this embodiment.

[0168] For example, in one example, see Figure 9-1 As shown, the area of ​​the wall contact area 912 is a plane area where the front surface of the substrate directly contacts the wall body 90, and the connection transition area 913 is an inclined area connecting the wall contact area 912 and the functional area 11. The setting of the connection transition area 913 can further increase the path between the wall contact area 912 and the functional area 911, thereby improving the moisture-proof performance of the bracket.

[0169] For example, in one example, see Figure 9-2 As shown, the area of ​​the wall contact area 912 is a plane area where the front surface of the substrate directly contacts the wall body 90, and the connecting transition area 913 is an arc surface area connecting the wall contact area 912 and the functional area 11. Figure 9-2 In the example shown, the arc surface area is a concave arc surface area that is concave toward the back of the substrate 91. The transition connection area of ​​the concave arc surface area can further increase the path between the wall contact area 912 and the functional area 911 relative to the inclined transition connection area, thereby further improving the moisture resistance and strength of the bracket. In this embodiment, when the connection transition area 913 is a curved surface area connecting the wall contact area 912 and the functional area 11, it can also be a convex arc surface area that bulges toward the top of the front of the substrate 91, see Figure 9-4 As shown, the relative slope transition connection area can further increase the path between the wall contact area 912 and the functional area 911, and can further enhance the moisture resistance and strength of the bracket.

[0170] In this embodiment, the connecting transition area may also be a combined surface, and the combined surface may include but is not limited to a combination of at least two of a plane, an inclined surface, and an arc surface.

[0171] For example, in one example, see Figure 9-3 As shown, the area of ​​the wall contact area 912 is a planar area where the front side of the substrate is in direct contact with the wall body 90, and the connecting transition area 913 is a combined surface composed of a planar area and a sloped area connecting the wall contact area 912 and the functional area 911 on the front side of the substrate. The combined surface can also further increase the path between the wall contact area 912 and the functional area 911 to improve the moisture-proof performance.

[0172] For example, see Figure 9-5As shown, the area of ​​the wall contact area 912 is a plane area where the front surface of the substrate directly contacts the wall body 90, and the connecting transition area 913 is a combination surface of a plane and an arc surface connecting the wall contact area 912 and the functional area 911 on the front surface of the substrate, and the arc surface is a convex arc surface area protruding upward from the front surface of the substrate 91. For another example, see Figure 9-6 As shown, it is Figure 9-5 The difference of the bracket shown is that the connection transition area 913 is composed of a plane and a concave arc area. The combined surface can also further increase the path between the wall contact area 912 and the functional area 911 to improve the moisture-proof performance.

[0173] In addition, it should be understood that the connection transition areas 913 on opposite sides of the front surface of the substrate in this embodiment can also be set as the same type of surface, or set as different types of surfaces. Figure 9-8 As shown, the connection transition zone 913 on one side of the substrate is set as a combination surface of a plane and a slope, and the connection transition zone 913 on the other side is a combination surface of a plane and a concave arc surface. The specific setting method can be flexibly determined according to the specific application scenario and the process adopted.

[0174] In addition, in this embodiment, a connection transition area is further provided between the wall contact area and the functional area on the substrate, which can at least partially directly contact the wall contact area 912, so as to simultaneously increase the contact area between the substrate and the wall body. Figure 9-7 As shown, the combined surface 913 composed of the inclined surface and the plane is in direct contact with the wall contact area 912, which can further increase the contact area between the substrate and the wall body, thereby increasing the strength of the bracket; at the same time, it can further improve the air tightness of the bracket to further improve the moisture-proof performance.
