Description

Technical Field

[0001] This utility model belongs to the field of LED light module technology, specifically relating to an aluminum alloy auxiliary heat dissipation structure for an integrated LED light module. Background Technology

[0002] An LED light module is a product that arranges multiple light-emitting diodes (LEDs) in a certain pattern and then encapsulates them. A simple LED light module consists of a circuit board containing LEDs and a housing. More complex modules will also include control, constant current sources, and heat dissipation components. These modules are usually also waterproofed to adapt to various environmental requirements. Simply put, an LED light module is an assembly that combines multiple LED beads together.

[0003] Existing LED light modules rely on aluminum profiles for support, connection, and heat dissipation. Since aluminum profiles are mostly integral structures surrounding the outside of the LED light module, they are fixed by interlocking with corner bracket components. Usually, threaded holes are opened on the corner brackets. The corner brackets are placed into the cavities of the aluminum profiles, and the corner brackets are fixed to the aluminum profiles with screws. However, screw connections are prone to loosening and the fastening effect is not good. Utility Model Content

[0025] This specific embodiment is an aluminum alloy auxiliary heat dissipation structure for an integrated LED light module, and its structural schematic diagram is shown below. Figures 1-6 As shown, the structure includes an aluminum alloy frame 1 and connectors 2. The aluminum alloy frame 1 includes two horizontal bars 101 and two vertical bars 102. The horizontal bars 101 and vertical bars 102 are made of 6303 aluminum alloy, which has good strength, wear resistance, and heat dissipation performance. The cross-sectional width of the horizontal bars 101 and vertical bars 102 is 21.31mm-21.33mm, and the cross-sectional height of the horizontal bars 101 and vertical bars 102 is 6.80mm-6.82mm. The cross-section of both the horizontal bars 101 and vertical bars 102 includes a rectangular main body 103. The main body 103 has multiple cavities 104 from left to right. The cavities 104 pass through the horizontal bar 101 and the vertical bar 102. The connector 2 includes a connector 201. Multiple connector arms 202 are fixedly connected to both sides of the connector 201. The connector arms 202 are inserted into the cavity 104. The inner side of the connector arm 202 has a groove 203. The inner wall of the cavity 104 is provided with a protrusion 204 corresponding to the groove 203. By making the protrusion 204 fit into the groove 203, there is no need to use screws for connection, avoiding loosening and improving the fastening effect.

[0026] like Figure 1 and Figure 6As shown: In this embodiment, U-shaped grooves 1031 are provided on both the left and right sides of the main body 103, and L-shaped grooves 1032 are provided on both the left and right sides of the upper surface of the main body 103. The U-shaped grooves 1031 are located at the bottom of the left and right sides of the main body 103, and the two L-shaped grooves 1032 are symmetrically arranged on the left and right sides of the main body 103. The U-shaped grooves 1031 penetrate the horizontal bar 101 and the vertical bar 102, and the L-shaped grooves 1032 penetrate the horizontal bar 101 and the vertical bar 102. The U-shaped grooves 1031 and the L-shaped grooves 1032 can increase the area of ​​the outer surface of the main body 103, better allow the outer side to contact the air, and improve the heat dissipation effect of the aluminum alloy frame 1.

[0027] like Figure 1 and Figure 6 As shown: In this embodiment, there are 7 cavities 104 with their lower surfaces flush. The distance between the cavity 104 and the upper surface of the main body 103 is greater than the distance between the cavity 104 and the lower surface of the main body 103. In this way, the main body 103 is a heat source, and the cavity 104 not only reduces weight and manufacturing cost, but also makes the aluminum alloy frame 1 have high mechanical strength as a whole.

[0028] like Figure 6 As shown: In this embodiment, the cross-section of the cavity 104 is rectangular, and the lateral width of the cavity 104 is smaller than its vertical width. The cavity 104 includes five first through holes 1041 and two second through holes 1042. The height of the first through holes 1041 is greater than the height of the second through holes 1042. The five first through holes 1041 are located in the middle of the main body 103, and the two second through holes 1042 are located on the left and right sides of the five first through holes 1041. The smaller second through holes 1042 are set on the left and right sides of the aluminum alloy frame 1, which will not affect the mechanical strength of the side of the aluminum alloy frame 1.

[0029] like Figure 2-5 As shown: In this embodiment, a right angle 2011 is provided on the inner side of the connector 201, and an arc groove 2012 is provided at the corner of the right angle 2011; the arc groove 2012 can reduce the stress at the right angle 2011 of the connector 201, thereby improving the strength and life of the connector 2.

[0030] like Figure 4 and Figure 5 As shown: In this embodiment, there are 7 connecting arms 202. The connecting arms 202 are provided with through holes 2021. Reinforcing ribs 2022 are fixedly connected between the inner walls of the through holes 2021. The through holes 2021 can reduce the weight of the connecting arms 202, thereby reducing the cost of the connector 2. The connector 2 is made of aluminum alloy.

[0031] Working principle: During assembly, the ends of the cut horizontal bar 101 and vertical bar 102 are beveled at 45 degrees. Then, the connecting arms 202 at both ends of the connector 2 are inserted into the beveled horizontal bar 101 and vertical bar 102. At this time, the connecting arms 202 will be inserted into the cavity 104 on the main body 103. Then, the machine will break through the inner wall of the cavity 104 to form a protrusion 204, and make the protrusion 204 fit into the groove 203 until the two horizontal bars 101 and two vertical bars 102 are spliced ​​into one piece, thereby avoiding loosening after connection and achieving a better fastening effect.

[0032] All technical features in this embodiment can be freely combined according to actual needs.

[0033] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
