Technical Field

[0001] This utility model relates to the technical field of LED light strips, and in particular to a heat dissipation metal strip for LED light strips. Background Technology

[0002] An LED light is an electroluminescent semiconductor chip that is cured onto a support using silver or white glue. Then, silver or gold wires are used to connect the chip to the circuit board. The entire chip is sealed with epoxy resin to protect the internal core wires. Finally, a housing is installed. Therefore, LED lights have good shock resistance.

[0003] Currently, existing LED lights generate heat when they are powered on and emit light. Heat is currently dissipated through a metal strip on the back of the LED light, but this heat dissipation efficiency is low. When the LED light is used for a long time, the heat dissipation efficiency cannot keep up. Therefore, a heat dissipation metal strip for LED light strips is designed to enhance the heat dissipation capacity of the metal strip, improve the heat dissipation efficiency of the LED light, and extend the life of the internal chip of the LED light. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a heat dissipation metal strip for LED light strips.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A heat dissipation metal strip for LED light strips includes: a metal strip with a plurality of LED lights evenly spaced along the center of the metal strip; a protective railing at the center of the front of the metal strip; a heat spreader at the center of the back of the metal strip; a snowflake-shaped grid evenly spaced along the back of the heat spreader; honeycomb-shaped heat dissipation fins arranged within the snowflake-shaped grid; the honeycomb-shaped heat dissipation fins include hexagonal heat dissipation fins; a metal block is designed at the top of the center of the inner cavity of the hexagonal heat dissipation fins; the metal block is connected to the inner wall of the hexagonal heat dissipation fins by connecting posts; and a plurality of heat dissipation fin groups evenly spaced along the back of the heat spreader.

[0007] In one embodiment, a dustproof glass is provided on the raised side of the front of the guardrail, and the guardrail covers the LED light.

[0008] In one embodiment, the top and bottom of the guardrail are provided with heat dissipation holes at equal intervals along the horizontal direction, and the inner walls of the guardrail near the sides where the LED lights are located are provided with air guide holes at equal intervals along the vertical direction.

[0009] In one embodiment, the top and bottom of the metal strip are provided with slots at equal horizontal intervals, and the top view of the slots is rectangular.

[0010] In one embodiment, the honeycomb heat dissipation fins fill the snowflake-shaped mesh, the center of the snowflake-shaped mesh is located at the center of the heat spreader plate, and the width of the front of the snowflake-shaped mesh is greater than the width of the front of the heat spreader plate.

[0011] In one embodiment, the heat dissipation fin group is disposed between every two snowflake-shaped grids, and the heat dissipation fin group is composed of a plurality of heat dissipation fins, which are arranged at equal distances in the horizontal and vertical directions.

[0012] In one embodiment, the surfaces of the honeycomb heat dissipation fins and the heat dissipation fin assembly are both anodized, and the heat spreader corresponds to the LED chip.

[0013] Compared with the prior art, the present invention has at least the following advantages:

[0014] This utility model discloses a heat dissipation metal strip for LED light strips. By setting a heat dissipation plate in the central part of the back of the metal strip, the heat source of the LED light can be quickly and evenly diffused to the entire metal strip. At the same time, the snowflake-shaped grid composed of honeycomb heat dissipation fins on the metal strip can accelerate the heat transfer speed, thereby achieving the purpose of rapid heat dissipation.

[0015] At the same time, the air vents and heat dissipation holes designed on the guardrail work together to allow the protective outer shell to dissipate heat, achieving the purpose of rapid heat dissipation;

[0016] By using the connecting pillars designed in the hexagonal heat sink and in conjunction with the metal block, the honeycomb heat sink fins can quickly conduct and dissipate heat to the heat dissipation plate, thereby improving the heat dissipation efficiency of the LED light strip heat sink and solving the bottleneck of "heat not being able to be transferred out".

[0023] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

[0024] like Figure 1-4 As shown, a heat dissipation metal strip for LED light strips includes: a metal strip 1, with a plurality of LED lights 13 arranged at equal intervals along the horizontal direction in the center of the metal strip 1; a protective railing 11 arranged in the center of the front of the metal strip 1; a heat dissipation plate 15 arranged in the center of the back of the metal strip 1; a snowflake-shaped grid 12 arranged at equal intervals along the horizontal direction on the back of the heat dissipation plate 15; honeycomb-shaped heat dissipation fins 14 arranged in the snowflake-shaped grid 12; the honeycomb-shaped heat dissipation fins 14 include hexagonal heat dissipation fins 141; a metal block 143 is designed at the top of the center of the inner cavity of the hexagonal heat dissipation fins 141; the metal block 143 and the inner wall of the hexagonal heat dissipation fins 141 are connected to each other by connecting posts 142; and a plurality of heat dissipation fin groups 16 are arranged at equal intervals along the horizontal direction on the back of the heat dissipation plate 15.

[0025] It should be noted that each grid in the snowflake-shaped grid 12 is a honeycomb heat dissipation fin 14, and the heat spreader 15 is on the back of the LED 13 chip. Therefore, when several LEDs 13 on the metal strip 1 generate heat due to use, the temperature on their chips will be evenly transferred to the heat spreader 15. After the temperature is transferred to the heat spreader 15, it will be dissipated through the honeycomb heat dissipation fins 14 in the snowflake-shaped grid 12. The connecting post 142 will guide the hexagonal heat sink 141 from the side close to the heat spreader 15 to the metal block 143 away from the side, realizing the overall heat dissipation of the back of the metal strip 1. At the same time, the heat dissipation fin group designed on it can further realize the heat dissipation.

[0026] like Figure 1-4 As shown in one embodiment, a dustproof glass 17 is provided on the protruding side of the front of the protective railing 11, and the protective railing 11 covers the LED light 13. It should be noted that this design allows the protective railing 11 to serve the purpose of protecting the LED light 13.

[0027] like Figure 1-4 As shown in one embodiment, the top and bottom of the guardrail 11 have horizontally spaced heat dissipation holes 111, and the inner walls of the guardrail 11 near the LED lights 13 have vertically spaced air vents 112. It should be noted that the guardrail 11 has a hollow inner cavity, so the air vents 112 can dissipate heat from the heat dissipation holes 111 through the chimney effect.

[0028] like Figure 1-4 As shown in one embodiment, the top and bottom of the metal strip 1 are provided with slots 18 at equal horizontal intervals, and the top view of the slots 18 is rectangular. It should be noted that the slots 18 are designed to facilitate binding by workers.

[0029] like Figure 1-4 As shown, in one embodiment, the honeycomb heat dissipation fins 14 are filled with snowflake-shaped mesh 12, the center of which is located at the center of the heat spreader 15, and the width of the front side of the snowflake-shaped mesh 12 is greater than the width of the front side of the heat spreader 15. It should be noted that this design increases the size of the snowflake-shaped mesh 12, thereby enhancing the area for heat dissipation.

[0030] like Figure 1-4 As shown, in one embodiment, the heat dissipation fin assembly 16 is disposed between every two snowflake-shaped grids 12. The heat dissipation fin assembly 16 is composed of a plurality of heat dissipation fins, which are arranged at equal distances in both the horizontal and vertical directions. The surfaces of the honeycomb heat dissipation fins 14 and the heat dissipation fin assembly 16 have been anodized. The heat spreader 15 corresponds to the chip of the LED lamp 13. It should be noted that this design not only enhances the formation of a protective layer but also significantly improves the surface emissivity (blackbody radiation effect), thereby enhancing the heat dissipation capacity.

[0031] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
