Embodiment Construction

[0016] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0017] see Figure 2-4 , The present invention relates to a surface mount light-emitting diode tall cup holder, which includes a cup body 1, a base 2, a reflective cup 103 and pins 3. The base 2 is provided with a cup body 1 , a reflective cup 103 is provided in the cup body 1 , and the bottom of the reflective cup 103 forms a wafer placement surface 104 .

[0018] In the present invention, the overall height b of the support, that is, the total height of the cup body 1 and the base 2 is generally different from that of the traditional support by 1.7-1.9mm, and its total height b should not be less than 2mm. According to the test, when the height is higher than 2mm , its products can be more conveniently sealed with waterproof glue when u...

Abstract

The invention provides a high-cup-shaped light-emitting diode bracket with a surface mount device (SMD). The bracket comprises a base, a cup body, a light-reflecting cup and pins, wherein the cup body is arranged on the base; the light-reflecting cup is arranged in the cup body; a wafer placing surface is formed at the bottom of the light-reflecting cup; pins which are connected with the wafer placing surface are extended on two sides of the base; and the total height of the base and the cup body is not less than 2mm. The bracket has the advantages that: the total height of the bracket consisting of the base and the cup body is increased, so that in the process of manufacturing a display screen, the sealing operation is easy to realize; by adopting the structure that the pins are hidden into the bottom of the cup body, an exposed water-contacting area is effectively reduced and a better water-proof effect is achieved; and the increase of the widths of the pins improves the radiating property of a product, so that the light attenuation phenomenon of the product can be effectively reduced.

Description

technical field [0001] The invention relates to a bracket for a light-emitting element, in particular to a tall cup bracket for a surface mount light-emitting diode. Background technique [0002] With the rapid development of technology in recent years, users' requirements for the clarity of LED displays are also increasing. For LED displays, the best way to improve the clarity of images is to increase the distribution density of light-emitting diodes to reduce the pixel points. However, the current LED display screens used for outdoor or semi-outdoor products tend to be larger in size, and the height a of the light-emitting diode bracket of the existing small-pitch high-pixel surface mount (SMD-surface mount device) is only 1.7-1.9 mm, it is difficult to apply because the bracket is too short to seal the waterproof glue when making the display screen. In addition, the bottom pins of the light-emitting diodes of the existing SMD-surface mount device are wider than the upper...
