Description

Technical Field

[0001] The utility model belongs to the technical field of LED brackets, in particular to a LED bracket structure with a window. Background Art

[0002] An LED bracket is a structural component used to support and fix a light-emitting diode (LED). It is usually composed of a substrate, electrodes, a reflector cup, a lens or packaging material, a heat dissipation structure, and a support structure. In order to improve the conductivity and reflectivity of the LED bracket, manufacturers usually plate a layer of silver on the surface of the substrate.

[0003] like Figure 1 As shown, the silver plating method of the prior art is usually to divide the substrate into a pin area and a functional area, and silver plating is performed on the pin area and the functional area of the substrate. In order to reduce costs, the thickness of the silver layer in the functional area is usually greater than the thickness of the silver layer in the pin area, that is, the pin area adopts single-layer silver plating and the functional area adopts double-layer silver plating.

[0004] When using this pin to injection-mold a cup body, the window position on the bottom surface of the cup body does not necessarily occupy the functional area between the two pin areas. Therefore, a portion of the second silver plating layer will be wasted in the functional area. Although the volume of the wasted silver layer is very small, due to the large number of brackets, the use of this technology for silver plating will result in a huge cost waste. Utility Model Content

[0005] The purpose of the present invention is to provide a windowed LED bracket structure to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A windowed LED bracket structure includes a plurality of pins, wherein the area where the pins are close to each other forms a functional area, and the functional area corresponding to the position of the cup window is provided with a first silver-plated layer; the other area of the pins is set as a pin area, and the pin area is provided with a second silver-plated layer, and the silver plating thickness of the first silver-plated layer is greater than the silver plating thickness of the second silver-plated layer.

[0008] According to a further technical solution, a cup body is injection-molded on a plurality of pins, and the bottom surface of the cup body is a closed curve.

[0009] According to a further technical solution, the closed curve may be a quadrilateral curve.

[0010] According to a further technical solution, protrusions are provided on the portions of the pins that abut against the bottom surface of the cup body.

[0012] According to a further technical solution, the plurality of pins include a common pin, and the common pin is in an "L" shape tilted 90 degrees to the right.

[0013] Beneficial effects of the utility model:

[0014] By connecting to an external control panel through several pins, the operator can more conveniently control the turning on and off of the LED light. Silver plating on the pin area and functional area of several pins is beneficial to improving conductivity. The silver plating thickness at the position corresponding to the cup window on the functional area is set to be greater than the silver plating thickness in the pin area, which can improve conductivity while reducing silver plating costs.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0021] Please refer to Figure 1-3 ;

[0022] The utility model discloses a windowed LED bracket structure, comprising a plurality of pins, which are configured as four pins in this embodiment. The four pins include a common pin 2 and three control pins 4. The common pin 2 is in an "L" shape tilted 90 degrees to the right. The control pin 3 of the four pins is used to connect to an external control panel. The area where the four pins are close to each other forms a functional area 5. The other areas of the four pins are configured as pin areas 4. The functional areas 5 of the four pins are provided with a first silver plating layer corresponding to the window position of the cup body 1; the pin areas 4 are provided with a second silver plating layer. Since the pin area 4 is mainly used to achieve electrical connection between the LED chip and the external control panel, the pins transmit current from the power supply to the LED chip, thereby causing it to emit light. The functional area 5 is mainly used to install and fix the LED chip and optimize light output and distribution. Therefore, a thicker silver layer is required in the functional area 5 to improve thermal conductivity, light reflectivity, and mechanical strength, thereby optimizing the heat dissipation and optical performance of the LED. The pin area 4 mainly focuses on electrical connection and basic corrosion resistance. Therefore, the silver plating thickness can be relatively thin to meet basic requirements and control costs. That is, the silver layer thickness of the first silver plating layer is greater than the silver layer thickness of the second silver plating layer.

[0023] The traditional method of silver plating pins is to first punch the substrate to form the pins, and then electroplate a layer of silver on the pin surface. After that, the functional area 5 and the pin area 4 are divided as follows: Figure 1 As shown, then Figure 1 The functional area shown is plated with a layer of silver, so that the thickness of the silver layer in the functional area 5 is greater than the thickness of the silver layer in the pin area 4. However, when the pin is used to inject the cup body 1, the window position on the bottom surface of the cup body 1 does not necessarily occupy the functional area 5 located between the two pin areas 4. Therefore, a part of the second silver plating layer will be wasted on the functional area 5. Although the volume of the wasted silver layer is very small, due to the large number of brackets, the use of this technology for silver plating will result in a huge cost waste.

[0024] Therefore, in this embodiment, the method for manufacturing the bracket is to first punch out the substrate to form pins, electroplate a layer of silver on the surface of the pins, and then use tools to cover other areas except the window position of the cup body 1 corresponding to the functional area 5, so that when the silver layer is electroplated for the second time, silver is only plated on the window position of the cup body 1 corresponding to the functional area 5, thereby reducing the silver plating area, reducing costs, and improving resource utilization.

[0025] In this embodiment, a cup body 1 is injection-molded on several pins. The bottom surface of the cup body 1 is a closed curve, and the bottom surface of the cup body 1 has a quadrilateral curve 6. When silver plating is performed in this embodiment, the operator first performs a first silver plating on the functional area 5 and the pin area 4, and then performs a second silver plating on the functional area 5 corresponding to the quadrilateral curve 6. Furthermore, in order to better enable the silver plating mold to silver plate the functional area 5, a protrusion 7 is provided at the abutting portion between the pin and the cup body 1. Correspondingly, a groove is provided on the silver plating mold to align the silver plating mold with the functional area 5.

[0026] In this embodiment, the inner wall of the cup body 1 is provided with a reflective coating 8. In actual application, when the lamp beads in the packaging bracket are lit, the reflective coating 8 on the side wall of the cup body 1 can effectively reflect the light outward, thereby improving the brightness.

[0027] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementations that can be understood by those skilled in the art.
