Description

Technical Field

[0001] This utility model relates to the field of semiconductor technology, and in particular to an LED bracket, LED beads and display device. Background Technology

[0002] Current LED chips are encapsulated using an LED bracket combined with encapsulating adhesive. The LED chip is housed within the cup of the LED bracket, and a conductive metal sheet is placed at the bottom of the LED bracket.

[0003] The brightness requirements for white LED beads are getting higher and higher. The key to improving brightness is to maximize the reflection of the light emitted by the chip inside the LED bracket cup. Therefore, the conductive metal sheet at the bottom of the LED bracket is silver-plated and the top surface of the LED bracket is made white.

[0004] However, in the LED manufacturing process, before the entire LED support is cut into individual LEDs, they are stacked together. The bottom surface of the upper LED support rubs against the top surface of the lower LED support, and the silver plating layer is easily rubbed together, causing the top surface of the LED support to turn black. After being cut into individual LEDs, when they are vibrated and sorted in the spooling disc of the beam splitter, the silver plating layer easily rubs the disc black. The blackened disc then rubs the white top surface of the LED LED with its top surface facing down. In addition, the friction between the top surface of the individual LED and the bottom surface of other LEDs also causes the top surface to turn black. After the top surface is blackened, the light reflection effect is weakened, which has a negative impact on the light efficiency of the LED. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an LED bracket, LED beads and display device, which aims to solve the problem that the silver plating layer on the bottom surface of the LED bracket is easily worn black during the processing due to friction.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0007] An LED bracket includes a bracket body. One side of the bracket body has a receiving groove for accommodating LED chips and encapsulating adhesive. The side of the bracket body facing away from the receiving groove is provided with a silver plating layer, a plurality of short surrounding strips, a plurality of long surrounding strips, and a P / N junction. A first set of protruding strips is provided on the side of the plurality of short surrounding strips or the plurality of long surrounding strips facing away from the bracket body. The first set of protruding strips includes a first protruding strip and a second protruding strip, which are arranged opposite to each other. The silver plating layer is located between the first protruding strip and the second protruding strip, and both the first protruding strip and the second protruding strip are higher than the silver plating layer.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting the first convex strip and the second convex strip higher than the silver plating layer, black powder is prevented from being generated by friction between the silver plating layer and the plane of the circular vibrating disk. When the top of one LED bracket and the bottom of another LED bracket rub against each other, the contact area is small, which greatly reduces the area of ​​blackening on the top.

[0009] Furthermore, a second set of protruding strips is provided on the side of the bracket body facing away from the silver plating layer. The second set of protruding strips includes a third protruding strip and a fourth protruding strip. The third protruding strip and the fourth protruding strip are arranged opposite to each other, and the receiving groove is located between the third protruding strip and the fourth protruding strip.

[0010] Furthermore, the silver plating layer is connected to both opposite sidewalls of the P / N junction.

[0011] Furthermore, the two ends of the P / N junction are respectively connected to the long strip.

[0012] Furthermore, a fifth protrusion is provided on the side of the P / N junction facing away from the main body of the support.

[0013] Furthermore, the horizontal cross-sectional area of ​​the first and second protrusions gradually decreases from the support body towards the direction where the first protrusion is away from the support body.

[0014] Furthermore, the horizontal cross-sectional area of ​​the third and fourth protrusions gradually decreases from the support body towards the direction of the third protrusion away from the support body.

[0015] An LED light bead includes an LED bracket as described in the above technical solution.

[0016] A display device includes LED beads as described in the above technical solution. Attached Figure Description

Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] Please see Figures 1 to 3The LED bracket in this embodiment of the present invention includes a bracket body 100. A receiving groove 110 is formed on one side of the bracket body 100. The receiving groove 110 is used to receive LED chips and encapsulating adhesive. A silver plating layer 120, several short surrounding strips 103, several long surrounding strips 104, and a P / N junction 105 are provided on the side of the bracket body 100 facing away from the receiving groove 110. A first set of protruding strips is provided on the side of the short surrounding strips 103 or the long surrounding strips 104 facing away from the bracket body 100. The first convex strip group includes a first convex strip 210 and a second convex strip 220, which are arranged opposite to each other. The silver plating layer 120 is located between the first convex strip 210 and the second convex strip 220. Both the first convex strip 210 and the second convex strip 220 are higher than the silver plating layer 120. The horizontal cross-sectional area of ​​the first convex strip 210 and the second convex strip 220 gradually decreases from the bracket body 100 in the direction from the first convex strip 210 away from the bracket body 100. Preferably, the bracket body 100 is a cuboid with a short side 101 and a long side 102. The short surrounding strips 103 correspond to the short side of the rectangle, and the long surrounding strips 104 correspond to the long side of the rectangle. That is, the number of short surrounding strips 103 is 2, and the number of long surrounding strips 104 is 2. The first protrusion 210 and the second protrusion 220 are respectively disposed on two of the short surrounding strips 103 or respectively disposed on two of the long surrounding strips 104. The cross-sectional shape of the first protrusion 210 and the second protrusion 220 can be semi-circular, trapezoidal, or triangular, etc. Specifically, the side of the first protrusion 210 facing away from the bracket body 100 forms a first inclined surface, and the side of the second protrusion 220 facing away from the bracket body 100 forms a second inclined surface. The LED bracket is made of white EMC adhesive. The bottom surface of the bracket body 100 is provided with a metal layer, and silver plating is applied to the metal layer to form the silver plating layer 120. The first protrusion 210 and the second protrusion 220 are both triangular prisms with right-angled triangles in cross-section. The right-angled sides of the right-angled triangles face the silver plating layer 120. It can be understood that when the LED bracket is vibrating and sorting in the circular vibrating disk, the silver plating layer 120 on the bottom surface cannot contact the plane of the circular vibrating disk under the action of the first protrusion 210 and the second protrusion 220. This can avoid the generation of black silver powder oxidation powder by friction with the plane, and greatly reduce the degree of blackening of the top surface of the LED bracket by the circular vibrating disk. When multiple LED brackets rub against each other, the first protrusion 210 and the second protrusion 220 can prevent the white adhesive top surface of the LED bracket from rubbing against the silver plating layer 120.

[0030] A second set of protruding strips is provided on the side of the bracket body 100 facing away from the silver plating layer 120. The second set of protruding strips includes a third protruding strip 230 and a fourth protruding strip 240. The third protruding strip 230 and the fourth protruding strip 240 are arranged opposite to each other. The receiving groove 110 is located between the third protruding strip 230 and the fourth protruding strip 240. The horizontal cross-sectional area of ​​the third protruding strip 230 and the fourth protruding strip 240 gradually decreases from the bracket body 100 toward the direction of the third protruding strip 230 facing away from the bracket body 100. Preferably, the cross-sectional shape of the third protrusion 230 and the fourth protrusion 240 can be semi-circular, trapezoidal, or triangular. Specifically, the side of the third protrusion 230 facing away from the support body 100 forms a third inclined surface, and the side of the fourth protrusion 240 facing away from the support body 100 forms a fourth inclined surface. Both the third protrusion 230 and the fourth protrusion 240 are triangular prisms with right-angled triangular cross-sections. Understandably, when the top of the LED support contacts the circular vibrating disk, only the edges of the protrusions contact the surface of the circular vibrating disk, which can prevent large areas of the top surface of the LED support from being worn black.

[0031] The silver plating layer 120 is connected to both opposite side walls of the P / N junction 105, and the long strips 104 are connected to both ends of the P / N junction 105. A fifth protrusion 250 is provided on the side of the P / N junction 105 facing away from the bracket body 100. Preferably, the highest point of the top of the LED bracket is the two edges on both sides. If the top of the LED bracket comes into contact with black powder, only the edges will be blackened. The same applies to the bottom of the LED bracket. When two LED brackets are stacked, since the bevels of the protrusions are clean, only the edges of the protrusions may be blackened. Therefore, the white adhesive on the bevels can remain clean when stacking.

[0032] Please see Figure 4 In a traditional LED bracket, the top first plane 130 is white, while the bottom second plane 140 is silver-plated. Friction between two such brackets can result in direct friction between the first plane 130 and the second plane 140. The black powder generated from this friction will directly coat the first plane 130, causing it to become blackened. This weakens the light reflection effect and negatively impacts the luminous efficacy of the LEDs made from the traditional bracket. Please refer to [link / reference]. Figure 5 and Figure 6When the length directions of the two LED brackets are parallel, they rub against each other. The third protrusion 230 is blocked by the fifth protrusion 250 before contacting the silver plating layer 120. If the LED brackets are tilted, only the edges of the third protrusion 230 rub against the silver plating layer 120, preventing the third inclined surface from being worn black. If the length directions of the two LED brackets are perpendicular, although they cannot be blocked by the fifth protrusion 250, when one end of one of the LED brackets rubs against the silver plating layer 120, only the third protrusion 230 and the edge of the fifth protrusion 250 rub against the silver plating layer 120. The edge of the fourth protrusion 240 rubs against the silver plating layer 120, which can prevent the third and fourth inclined surfaces from being worn black. Furthermore, since both sides of the silver plating layer 120 are the higher ends of the first protrusion 210 and the second protrusion 220, the black powder will be blocked by the sidewall of the higher end of the protrusion, which can prevent the black powder from moving to the first and second inclined surfaces during vibration and shaking, and further reduce the possibility of the third and fourth inclined surfaces turning black when the first inclined surface contacts the third inclined surface or the second inclined surface contacts the fourth inclined surface.
