Technical Field

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

[0002] With the development of the industry, LED devices are being used in a wider range of fields. In some special applications, there are higher requirements for the airtightness and breaking strength of LED brackets, which are currently insufficient to meet the needs. Utility Model Content

[0003] In view of the above situation, it is necessary to provide an LED bracket that addresses the problems of low airtightness and low breaking strength of existing LED brackets.

[0004] An LED bracket includes a pad assembly and a surrounding portion. The pad assembly includes a positive pad and a negative pad disposed opposite to each other. The positive pad has a first curved portion, and the negative pad has a second curved portion. The first curved portion and the second curved portion are disposed opposite to each other, and a gap is formed between the first curved portion and the second curved portion. A first outer edge is provided along the top periphery of the positive pad, and a second outer edge is provided along the top periphery of the negative pad. The first outer edge and the second outer edge are positioned correspondingly and enclose each other to form a bowl shape. A first step is provided at the end of the positive pad away from the negative pad, and a second step is provided at the end of the negative pad away from the positive pad. The surrounding portion is provided on the outer periphery of the positive pad, the outer periphery of the negative pad, and the gap.

[0005] The beneficial effects of this utility model are:

[0006] With the positive and negative electrode pads arranged opposite each other, the first and second curved portions are also arranged opposite each other, forming a gap between the first and second curved portions. An enclosing portion is provided in the gap to increase the contact surface between the positive and negative electrode pads and the enclosing portion, thus extending the penetration path of water vapor or other gases. At the same time, the enclosing portion in the gap makes the connection between the first and second curved portions and the enclosing portion (compared to a plane) more robust, significantly enhancing the breaking strength of the positive and negative electrode pads. Furthermore, the outer periphery of the first and second outer edges, as well as the first and second step portions, are enclosed by the enclosing portion, further increasing the contact surface between the positive and negative electrode pads and the enclosing portion, and extending the penetration path of water vapor or other gases.

[0007] The first outer edge and the second outer edge are positioned correspondingly, and the first outer edge and the second outer edge together form a bowl shape. The first outer edge is connected to the positive electrode pad, and the second outer edge is connected to the negative electrode pad. To avoid short circuits, there is a gap between the first outer edge and the second outer edge.

[0008] Furthermore, a chip is provided on the top of both the positive electrode pad and the negative electrode pad.

[0009] Furthermore, the positive electrode pad is provided with a first injection hole on both sides opposite to each other. The first injection hole extends from the bottom of the positive electrode pad to the first outer edge. The negative electrode pad is provided with a second injection hole on both sides opposite to each other. The second injection hole extends from the bottom of the negative electrode pad to the second outer edge. The first injection hole and the second injection hole are respectively adapted to the injection molding machine.

[0010] Furthermore, the height of the first outer edge is the same as the height of the second outer edge, and the height of the top of the first outer edge and the top of the second outer edge are both less than the height of the top of the LED support cup.

[0011] Furthermore, the height of the top of the surrounding portion is lower than the height of the top of the first outer edge portion and the height of the top of the second outer edge portion.

[0012] Furthermore, both the first step portion and the second step portion are provided with protrusions, and the protrusions are serrated.

[0013] Furthermore, the material of the surrounding part is plastic. Attached Figure Description

[0021] An LED bracket, such as Figures 1 to 3 As shown, it includes a pad assembly 1 and a surrounding portion 2.

[0022] Specifically, the pad assembly 1 includes a positive pad 11 and a negative pad 12 arranged opposite to each other. The positive pad 11 has a first bent portion 111, and the negative pad 12 has a second bent portion 121. The first bent portion 111 and the second bent portion 121 are arranged opposite to each other, forming a gap portion 13. A first outer edge portion 112 is provided along the top periphery of the positive pad 11, and a second outer edge portion 122 is provided along the top periphery of the negative pad 12. The positions of the first outer edge portion 112 and the second outer edge portion 122 are corresponding. The first outer edge portion 112 and the second outer edge portion 122 enclose each other to form a bowl shape. The first outer edge portion 112 is connected to the positive pad 11, and the second outer edge portion 122 is connected to the negative pad 12. To avoid short circuits, there is a gap between the first outer edge portion 112 and the second outer edge portion 122. The height of the first outer edge 112 is the same as the height of the second outer edge 122, and both the height of the first outer edge 112 and the height of the second outer edge 122 are less than the height of the LED bracket cup. The positive electrode pad 11 has a first stepped portion 113 at the end away from the negative electrode pad 12, and the negative electrode pad 12 has a second stepped portion 123 at the end away from the positive electrode pad 11. Both the first stepped portion 113 and the second stepped portion 123 have protrusions (not shown), and the protrusions are serrated. With the positive electrode pad 11 and negative electrode pad 12 arranged opposite each other, the first curved portion 111 and the second curved portion 121 are also arranged opposite each other. The first curved portion 111 extends to the bottom of the second curved portion 121, and the second curved portion 121 extends to the top of the first curved portion 111, forming a gap 13. A surrounding portion 2 is provided in the gap 13 to increase the contact surface between the positive electrode pad 11 and the negative electrode pad 12 and the surrounding portion 2, thus extending the penetration path of water vapor or other gases. At the same time, with the surrounding portion 2 provided in the gap 13, the combination of the first curved portion 111 and the second curved portion 121 with the surrounding portion 2 (compared to a plane) is more firm, which significantly enhances the breaking strength of the positive electrode pad 11 and the negative electrode pad 12. The outer periphery of the first outer edge 112 and the outer periphery of the second outer edge 122, as well as the first unit The step portion 113 and the second step portion 123 are combined with the surrounding portion 2, further increasing the contact surface between the positive electrode pad 11 and the negative electrode pad 12 and the surrounding portion 2, and extending the penetration path of water vapor or other gases. The first step portion 113 and the second step portion 123 are both provided with serrated protrusions, which increase the contact surface between the positive electrode pad 11 and the negative electrode pad 12 and the surrounding portion 2, making the combination of the positive electrode pad 11 and the negative electrode pad 12 with the surrounding portion 2 (compared to a flat surface) more firm. In order to maintain a match with the height of the top of the LED lamp bead cup, the height of the top of the first outer edge portion 112 and the top of the second outer edge portion 122 need to be less than the height of the top of the LED bracket cup, that is, the height of the top of the first outer edge portion 112 and the top of the second outer edge portion 122 are both less than 0.4mm.

[0023] Specifically, a surrounding portion 2 is provided on the outer periphery of the positive electrode pad 11, the outer periphery of the negative electrode pad 12, and the gap portion 13. A first injection hole 114 is provided on opposite sides of the positive electrode pad 11, and a second injection hole 124 is provided on opposite sides of the negative electrode pad 12. The first injection holes 114 and the second injection holes 124 are adapted to the injection molding machine. The surrounding portions 2 extend from the bottom of the positive electrode pad 11 towards the first outer edge 112 and from the bottom of the negative electrode pad 12 towards the second outer edge 122, respectively. The height of the top of the surrounding portion 2 is lower than the height of the top of the first outer edge 112 and the top of the second outer edge 122, respectively. The surrounding portion 2 is made of plastic. The injection molding machine injects plastic through the first injection hole 114 and the second injection hole 124 to form the surrounding part 2, so that the surrounding part 2 wraps the positive electrode pad 11 and the negative electrode pad 12 more tightly. At the same time, the top of the surrounding part 2 is lower than the top of the first outer edge 112 and the top of the second outer edge 122, which fully increases the contact surface between the positive electrode pad 11 and the negative electrode pad 12 and the surrounding part 2, without affecting the relevant operation, so that the positive electrode pad 11 and the negative electrode pad 12 are tightly bonded to the surrounding part 2, thereby improving the airtightness of the LED bracket.

[0024] Specifically, chip 3 is provided on the top of both the positive electrode pad 11 and the negative electrode pad 12.

[0025] In this invention, positive electrode pad 11 and negative electrode pad 12 are arranged opposite each other, with the first curved portion 111 and the second curved portion 121 also arranged opposite each other to form a gap portion 13. A surrounding portion 2 is provided in the gap portion 13 to increase the contact surface between the positive electrode pad 11 and the negative electrode pad 12 and the surrounding portion, thus extending the permeation path of water vapor or other gases. At the same time, the combination of the gap portion 13 with the surrounding portion and the first curved portion 111 and the second curved portion 121 with the surrounding portion 2 (compared to a plane) is more firm, which significantly enhances the breaking strength of the positive electrode pad and the negative electrode pad. The outer periphery of the first outer edge portion 112 and the outer periphery of the second outer edge portion 122, as well as the first step portion 113 and the second step portion 123 are surrounded by the surrounding portion 2, further increasing the contact surface between the positive electrode pad 11 and the negative electrode pad 12 and the surrounding portion 2, and extending the permeation path of water vapor or other gases.
