Description

Technical Field

[0001] This application relates to the field of LED product technology, specifically to an LED lamp bead and a light-emitting device. Background Technology

[0002] In traditional chip-type LED chips, the maximum thickness of the bracket is 1 mm. Brackets thicker than 1 mm generally require FR-4 material, necessitating custom manufacturing and incurring higher costs. However, in specialized applications such as medical endoscopes or NFC payment devices, where the bracket thickness is smaller, the LED chip is embedded inside the device. This results in the light emission being blocked by the device, leading to a narrower light emission angle and lower brightness, failing to meet application requirements. Utility Model Content

[0003] In view of this, this application provides an LED lamp bead and a light-emitting device with a large light-emitting angle and high brightness.

[0004] To achieve the above objectives, this application provides the following technical solution:

[0005] An LED light bead, comprising:

[0006] The main body of the LED bead has a first electrode and a second electrode;

[0007] A raised block has a first side and a second side opposite to each other. A first conductive part and a second conductive part are provided on the first side of the raised block, and a third conductive part and a fourth conductive part are provided on the second side of the raised block. The first conductive part and the third conductive part are electrically connected through a first connecting part, and the second conductive part and the fourth conductive part are electrically connected through a second connecting part.

[0008] The lamp bead body is connected to the first side of the raised block, and the first conductive part is electrically connected to the first electrode, and the second conductive part is electrically connected to the second electrode.

[0009] Optionally, the shim block has a third side and a fourth side opposite to each other, the third side and the fourth side of the shim block being located between the first side and the second side of the shim block, and the first connecting portion and the second connecting portion being respectively disposed on the third side and the fourth side of the shim block.

[0010] Optionally, the raised block is provided with a first through hole and a second through hole, both of which penetrate the first side and the second side of the raised block. The first connecting part is disposed in the first through hole, and the second connecting part is disposed in the second through hole.

[0011] Optionally, the first through hole is located in the middle of the first conductive part and the third conductive part, and the second through hole is located in the middle of the second conductive part and the fourth conductive part.

[0012] Optionally, the first connecting part is disposed on the inner wall of the first through hole, the second connecting part is disposed on the inner wall of the second through hole, and a filler is disposed in both the first through hole and the second through hole.

[0013] Optionally, the first conductive portion and the second conductive portion, the third conductive portion and the fourth conductive portion, as well as the first connecting portion and the second connecting portion are all symmetrically arranged with respect to the same cross-section of the shim block.

[0014] Optionally, the distance between the first side and the second side of the shim block is 0.1-2 mm.

[0015] Optionally, the angle formed by the first side and the second side of the raised block is less than 3 degrees.

[0018] The LED lamp bead and light-emitting device provided in this application, when installing the lamp bead body, can connect the first electrode and the second electrode of the lamp bead to the circuit board by electrically connecting the third conductive part and the fourth conductive part on the shim block. Since the distance between the light-emitting chip of the lamp bead and the third conductive part and the fourth conductive part on the shim block is large, the installation position of the lamp bead body can be improved, and it will not be blocked by other surrounding components. This increases the light-emitting angle and light-emitting brightness of the lamp bead body, which is beneficial to improving the light efficiency and light emission uniformity.

Detailed Implementation

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] like Figures 1-8 As shown, this application embodiment provides an LED lamp bead, including a lamp bead body 1 and a support block 2. The lamp bead body 1 has a bracket 13 and a light-emitting chip 14. The light-emitting chip 14 is disposed on the bracket 13. A first electrode 11 and a second electrode 12 are disposed on the side of the bracket 13 away from the light-emitting chip 14, and the light-emitting chip 14 is powered through the first electrode 11 and the second electrode 12. Here, the first electrode 11 and the second electrode 12 are the positive and negative electrodes of the lamp bead body 1, respectively. The shape of the lamp bead body 1 can be rectangular, square, or circular.

[0031] The shim block 2 has a first side and a second side. The shim block 2 can be set as a block structure or a sheet structure. When the shim block 2 is set as a block structure, the shape can be set as a cuboid or a prism. The first side and the second side are the two sides in the height direction of the block structure, that is, the upper side and the lower side. When the shim block 2 is set as a sheet structure, the first side and the second side are the two sides in the thickness direction of the sheet structure.

[0032] The raised block 2 is provided with a first conductive part 21, a second conductive part 22, a third conductive part 23, a fourth conductive part 24, a first connecting part 25, and a second connecting part 26. The first conductive part 21 and the second conductive part 22 are spaced apart on the first side of the raised block 2, and the third conductive part 23 and the fourth conductive part 24 are spaced apart on the second side of the raised block 2. The first conductive part 21 and the third conductive part 23 are electrically connected through the first connecting part 25, and the second conductive part 22 and the fourth conductive part 24 are electrically connected through the second connecting part 26, so that the first conductive part 21, the third conductive part 23, and the first connecting part 25 form a first conductive path, and the second conductive part 22, the fourth conductive part 24, and the second connecting part 26 form a second conductive path.

[0033] The lamp bead body 1 is connected to the first side of the raised block 2. The first electrode 11 of the lamp bead body 1 is electrically connected to the first conductive part 21. The second electrode 12 of the lamp bead body 1 is electrically connected to the second conductive part 22. Under the action of the first connecting part 25 and the second connecting part 26, the first electrode 11 of the lamp bead is electrically connected to the third conductive part 23, and the second electrode 12 of the lamp bead is electrically connected to the fourth conductive part 24.

[0034] When installing the lamp bead body 1, by electrically connecting the third conductive part 23 and the fourth conductive part 24 on the shim block 2 to the circuit board 3, the first electrode 11 and the second electrode 12 of the lamp bead can be connected to the circuit board 3. Since the distance between the light-emitting chip 14 of the lamp bead and the third conductive part 23 and the fourth conductive part 24 on the shim block 2 is large, the installation position of the lamp bead body 1 can be improved, and it will not be blocked by other surrounding components. This increases the light emission angle and light emission brightness of the lamp bead body 1, which is beneficial to improving the light efficiency and light emission uniformity.

[0035] In this solution, the lamp bead body 1 is welded to the first side of the shim block 2 by reflow soldering. The reflow soldering process can improve the connection strength between the lamp bead body 1 and the shim block 2, so that the thrust between the electrodes (first electrode 11 and second electrode 12) of the lamp bead body 1 and the conductive parts (first conductive part 21 and second conductive part 22) of the shim block 2 is greater than 100 g / L, which meets the product design requirements.

[0036] The edge spacing between the LED bead body 1 and the first side of the shim block 2 is 0.02-0.05 mm, meaning the size of the shim block 2 is slightly larger than that of the LED bead body 1. During LED bead processing, the substrate needs to be cut to form the shim block 2. Before cutting the substrate, the LED bead body 1 needs to be attached to it. After cutting, the LED bead body 1 and the shim block 2 are connected together. This design, by regulating the size of the shim block 2, avoids damage to the LED bead body 1 during cutting. Simultaneously, the shim block 2 only increases the longitudinal dimension of the LED bead body 1, without making the lateral mounting dimension of the LED bead body 1 too large. Here, the width, thickness, and diameter of the cutting burrs on the shim block 2 are all required to be less than 0.2 mm.

[0037] The distance between the first and second sides of the shim block 2 is 0.1-2 mm, so that the longitudinal height increase of the shim block 2 relative to the lamp bead body 1 is 0.1-2 mm. If the longitudinal height increase of the lamp bead body 1 is too small, the height increase effect will be insignificant and the cost will be increased unnecessarily. If the longitudinal height increase of the lamp bead body 1 is too large, the lamp bead body 1 will protrude too much, which will affect the installation strength of the lamp bead body 1.

[0038] In the specific design, the angle between the first and second sides of the shim block 2 is less than 3 degrees, so that the first and second sides are parallel or nearly parallel. This can prevent the light-emitting chip 14 on the lamp body 1 from tilting relative to the circuit board 3, which would affect the light output quality and light output angle.

[0039] In a first embodiment, the shim block 2 has opposing third and fourth sides, both of which are located between the first and second sides of the shim block 2, and are respectively connected to the first and second sides. For example, as... Figure 1 , 2 As shown, the first and second sides are the upper and lower sides of the shim block 2, and the third and fourth sides are the left and right sides of the shim block 2. The first connecting part 25 and the second connecting part 26 are respectively disposed on the third and fourth sides, so that the first conductive part 21, the third conductive part 23, and the first connecting part 25 are integrally formed, and the second conductive part 22, the fourth conductive part 24, and the second connecting part 26 are integrally formed. Thus, when processing the shim block 2, a metal layer can be electroplated on the sides of the shim block 2, which can form the first conductive part 21, the second conductive part 22, the third conductive part 23, the fourth conductive part 24, the first connecting part 25, and the second connecting part 26, making processing convenient and cost-effective.

[0040] In the second embodiment, the raised block 2 is provided with a first through hole and a second through hole at intervals, both penetrating the first and second sides of the raised block 2. A first connecting portion 25 is disposed within the first through hole, and a second connecting portion 26 is disposed within the second through hole. Thus, when the raised block 2 is cut, the cutting path will not pass through the first connecting portion 25 and the second connecting portion 26, avoiding burrs on the first connecting portion 25 and the second connecting portion 26 and improving the quality of the raised block 2.

[0041] The first connecting part 25 and the second connecting part 26 can be respectively embedded in the first through hole and the second through hole. The first connecting part 25 and the second connecting part 26 are processed by the copper plugging pillar process, so that the first connecting part 25 and the second connecting part 26 can be stably limited in the first through hole and the second through hole.

[0042] like Figure 4 As shown, the first connecting part 25 is disposed on the inner wall of the first through hole, and the second connecting part 26 is disposed on the inner wall of the second through hole. During processing, the first connecting part 25, the first conductive part 21 and the third conductive part 23 can be integrally electroplated, and the second connecting part 26, the second conductive part 22 and the fourth conductive part 24 can be integrally electroplated. This is beneficial for saving metal materials, and at the same time, there is no need to consider the size of the first through hole and the second through hole, which is beneficial for simplifying design requirements.

[0043] Furthermore, both the first and second through holes are provided with filler 27, so that the first connecting part 25 is limited between the filler 27 and the inner wall of the first through hole, and the second connecting part 26 is limited between the filler 27 and the inner wall of the second through hole, thereby further improving the installation strength and installation stability of the first connecting part 25 and the second connecting part 26.

[0044] The first through hole is located in the middle of the first conductive part 21 and the third conductive part 23, so that the first connecting part 25 is connected in the middle of the first conductive part 21 and the third conductive part 23, which helps to improve the connection stability of the first connecting part 25 and the conductivity of the first conductive path. The second through hole is located in the middle of the second conductive part 22 and the fourth conductive part 24, so that the second connecting part 26 is connected in the middle of the second conductive part 22 and the fourth conductive part 24, which helps to improve the connection stability of the second connecting part 26 and the conductivity of the second conductive path.

[0045] like Figure 1 , 2As shown, the first conductive part 21, the second conductive part 22, the third conductive part 23, the fourth conductive part 24, the first connecting part 25, and the second connecting part 26 are all symmetrically arranged with respect to the same cross-section of the shim block 2. That is, the first conductive path formed by the first conductive part 21, the third conductive part 23, and the first connecting part 25 is symmetrically arranged on the shim block 2 with the second conductive path formed by the second conductive part 22, the fourth conductive part 24, and the second connecting part 26. This is beneficial to improving the current stability of the connected lamp bead body 1 and the structural balance of the shim block 2.

[0046] This application provides a light-emitting device, which is equipped with LED beads as described in the above embodiments. By raising the main body 1 of the LED beads, the light emission angle and light emission quality of the main body 1 of the LED beads can be improved.

[0047] like Figure 5 , 6 As shown, the light-emitting device is set as a medical endoscope. In traditional medical endoscopes, the LED bead body 1 is embedded inside, resulting in a small light-emitting angle (only 86 degrees) and low brightness, which does not meet the application requirements. After adopting the LED bead in the above embodiment, the embedded LED bead body 1 can achieve a light-emitting angle of 120 degrees, and the light will not be blocked by other surrounding components. In addition, the embedded LED bead body 1 can be reinforced with a sealing shell after being attached, ensuring that the entire device will not be lost when inserted into the human body for detection and use.

[0048] like Figure 7 , 8 As shown, the light-emitting device is configured as an NFC payment device. In traditional NFC payment devices, the light emitted by the LED body 1 is blocked by the circuit board. With the LED light beads in the above embodiment, the LED body 1 is not blocked by the circuit board, the light emission is more uniform, the light emission angle is larger, and five-sided light emission of the LED body 1 can be achieved.
