Description

Technical Field

[0001] The utility model relates to the technical field of LEDs, in particular to an LED bracket and an LED component with the LED bracket. Background Art

[0002] Whether it is commercial advertising, public information display or event site control, digital display plays an important role. In outdoor applications, high brightness and contrast of the display are particularly important.

[0003] In outdoor environments, we often face strong sunlight and uneven lighting. Traditional displays often appear dim and weak under strong light, and cannot clearly display content. In addition to high brightness, contrast is also an essential feature in outdoor applications. Among them, contrast refers to the ability of the display to show the brightest and darkest areas at the same time. In outdoor environments, due to uneven lighting and interference from the surrounding environment, the contrast often becomes unclear, so outdoor LED displays need to improve their contrast.

[0004] However, when the contrast of outdoor LED display screen is improved, its stability is often not guaranteed. Usually, the packaging material of LED lamp beads is plastic or glass, which is relatively fragile and easily broken by external vibration. When the contrast of outdoor LED display screen is adjusted, the LED lamp beads may fall off easily when bumped, which cannot meet the requirements of market development.

[0005] Therefore, it is urgent to design a LED bracket suitable for outdoor display screens. Utility Model Content

[0006] In view of the deficiencies of the prior art, the utility model discloses an LED bracket and an LED component having the LED bracket.

[0007] The technical solution adopted by the utility model is as follows:

[0030] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0031] The above and other technical contents, features and effects of the present invention will be clearly presented in the following detailed description of the embodiments with reference to the accompanying drawings. The directional terms mentioned in the following embodiments, such as up, down, left, right, front or back, etc., are only the directions of the reference drawings. Therefore, the directional terms used are used to illustrate and not to limit the present invention. In addition, in all embodiments, the same reference numerals represent the same elements.

[0032] Embodiment 1

[0033] Reference Figure 1 As shown, an LED bracket includes:

[0034] The support body 100 is provided with a pin area;

[0035] The pin 200 is arranged in the pin area; the pin 200 includes a first connecting section 201 and a second connecting section 202 which are bent and connected, the first connecting section 201 is attached to the side wall of the bracket body 100, and the second connecting section 202 is away from the side wall of the bracket body 100, wherein the second connecting section 202 opens a through hole 300.

[0036] Compared to Figure 2 The existing LED bracket shown in the figure, the LED bracket provided in this embodiment increases the contact area between the pin 200 and the pad by changing the structure of the pin 200, thereby increasing the thrust; at the same time, the LED bracket provided in this embodiment increases the design of the through hole 300, increases the bonding force between the solder paste and the pad, and further prevents the LED lamp beads from falling off after being bumped.

[0037] In this embodiment, in order to describe the relationship between the various parts and components, a coordinate system is established with the center point of the bracket body 100 as the coordinate origin, the direction of the long side of the bracket body 100 as the X-axis direction, and the direction of the wide side of the bracket body 100 as the Y-axis direction.

[0038] The shape of the first connecting section 201 and the shape of the second connecting section 202 are both roughly rectangular, the first connecting section 201 extends along the X-axis direction, the second connecting section 202 extends along the Y-axis direction, and the central axis of the first connecting section 201 and the central axis of the second connecting section 202 intersect at one point. The angle formed between the first connecting section 201 and the second connecting section 202 is a right angle, that is, the degree of the angle formed between the first connecting section 201 and the second connecting section 202 is 90°.

[0039] The second connecting section 202 extends a preset distance along the width direction of the first connecting section 201, that is, the second connecting section 202 extends a preset distance along the Y-axis direction, and the second connecting section 202 does not contact the bracket body 100. Specifically, the preset distance is 0.05 mm±0.01 mm.

[0040] The shape of the through hole 300 is one of a circle, an ellipse and a polygon. When the shape of the through hole 300 is a circle, the diameter of the through hole 300 is 0.03 mm to 0.05 mm. The through hole 300 increases the soldering area between the pin 200 and the pad, thereby increasing the thrust of the pin 200.

[0041] There are four pins 200, and the four pins 200 are arranged in a 2×2 array. Specifically, every two pins 200 are located at the same height, and the second connection sections 202 of the pins 200 at the same height extend in the same direction, while the second connection sections 202 of the pins 200 at different heights extend in different directions.

[0042] It should be noted that when the central axis of the first connecting segment 201 is on the positive half axis of the Y axis, the extension direction of the second connecting segment 202 extends toward the positive direction of the Y axis; when the central axis of the first connecting segment 201 is on the negative half axis of the Y axis, the extension direction of the second connecting segment 202 extends toward the negative direction of the Y axis.

[0043] It is obvious that the existing LED bracket is only designed with a first connecting section 201, and the LED bracket provided in this embodiment adds a second connecting section 202, which significantly increases the contact area between the pin 200 and the pad and increases the bonding strength between the LED chip and the bracket body 100 under the action of an adhesive (such as glue).

[0049] Since this embodiment includes the LED bracket of the first embodiment, all the advantages of the first embodiment are also possessed by this embodiment.
