[0002] The existing LED Holder in the market is a plug-in lampled with a black base. The light-emitting source of the LED Holder is a plug-in lamp, and it adopts a potting form. The potting process is to first inject liquid epoxy resin into the LED forming cavity, then insert the welded LED bracket, put it into the oven to cure the epoxy resin, and then remove the LED from the cavity to form. The manufacturing process is relatively simple and the cost is low, but the power of the product itself is small and the light decay during continuous operation is large. Therefore, professionals in this field have provided a new type of patch LED base assembly to solve the above-mentioned problems. Content of the Utility Model

[0003] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a new type of patch LED base assembly, which is suitable for SMT processing and well solves the problems of brightness, viewing angle, flatness, reliability, consistency, etc. existing in the prior art.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions;

[0005] A new type of patch LED base assembly includes a black base. An installation groove is provided at the bottom of the black base. A patch LED is installed inside the installation groove. The light-emitting surface of the patch LED faces the inside of the black base. A white rubber colloid is installed on the black base. The white rubber colloid penetrates and extends to the outside of the black base. A thermal conductive silicone grease is connected between the white rubber colloid and the patch LED. Uniformly distributed heat sinks are connected to the thermal conductive silicone grease.

[0006] As a further description of the above technical solution: A notch is provided on the black base.

[0007] As a further description of the above technical solution: The surface of the white rubber colloid is roughened.

[0009] Compared with the prior art, the advantages of the utility model are as follows:

[0010] In the present utility model, a patch-type PLCC LED is introduced as a light source in cooperation with a black base. Since the PLCC product has a higher power and a smaller light decay during continuous operation compared with the LAMP product, it can provide higher brightness and stronger working life as a light source, increasing the diversity of products and the selectivity of market products. Compared with the prior art, the application of using patch LEDs as light sources in this application has a broader scope. It can be attached to the surface of the circuit board, suitable for SMT processing and reflow soldering, and well solves problems such as brightness, viewing angle, flatness, reliability, and consistency.

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0017] Please refer to Figures 1-3 , in the present utility model, a new type of patch-type LED base assembly includes a black base 1. An installation groove 2 is provided at the bottom of the black base 1. A patch-type lamp bead 3 is installed inside the installation groove 2. The light-emitting surface of the patch-type lamp bead 3 faces the inside of the black base 1. A white rubber colloid 4 is installed on the black base 1. The white rubber colloid 4 penetrates and extends to the outside of the black base 1. A thermal grease 5 is connected between the white rubber colloid 4 and the patch-type lamp bead 3. Heat sinks 6 are evenly distributed and connected to the thermal grease 5;

[0018] The surface of the white rubber colloid 4 is roughened.

[0019] During the assembly process, the surface-mounted lamp bead 3 serves as a light source and is placed at the bottom of the black base 1 with the soldering side facing outward and the light-emitting side facing inside the black base 1. A white rubber colloid 4 is placed on the top as the light-emitting surface. In actual use, the white rubber colloid 4 can be adjusted according to different requirements to achieve the desired light-emitting surface and light-emitting angle. The surface-mounted lamp bead 3 and the white rubber colloid 4 are installed inside the black base 1, and the black base 1 plays a role in fixing the light source and the colloid to prevent light leakage. Roughening the surface of the white rubber colloid 4 can increase the scattering of light, reduce specular reflection, and make the light more evenly distributed, improving the lighting effect. During operation, a thermal conductive silicone grease 5 is added between the white rubber colloid 4 and the black base 1 to improve the heat dissipation efficiency, effectively conducting the heat generated by the lamp bead to multiple heat sinks 6 and extending the service life.

[0020] In the present utility model, a surface-mounted plcc led is introduced as the light source in cooperation with the black base 1. Since the plcc product has a higher power and a smaller light decay during continuous operation compared with the lamp product, it can provide higher brightness and stronger service life as a light source, increasing the diversity of products and the selectivity of market products. Compared with the prior art, the present application using a surface-mounted LED as the light source has a wider range of applications. It can be attached to the surface of the circuit board, suitable for SMT processing and reflow soldering, and well solves problems such as brightness, viewing angle, flatness, reliability, and consistency.

[0021] Please refer to Figure 1 and 3 , wherein: a notch 7 is provided on the black base 1.

[0022] In the present utility model, the notch 7 is an important visual identifier, which enables the assembler to quickly distinguish the polarity of the LED.

[0023] Please refer to Figure 1 and 2 , wherein: the heat sink 6 is made of copper metal, and the heat sink 6 is inside the black base 1.

[0024] In the present utility model, the copper metal material has good heat dissipation effect, and multiple heat sinks 6 being inside the black base 1 can prevent the extension of the heat sink 6 from affecting the reflection of light.

[0025] The above is only the preferred specific embodiment of the present utility model; however, the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its improved concept, makes equivalent substitution or change, and should be covered by the protection scope of the present utility model.
