They all connect the expansion part with the rectangular frame through a resin bonding layer to prevent the two from separating and falling off. However, simply bonding through the resin bonding layer cannot effectively guarantee the connection stability between the above components. At the same time, they all fill liquid resin into a large-volume filling cavity or a storage area such as a receiving groove through a narrow opening for solidification. This makes the operation time-consuming and labor-intensive, and cannot effectively ensure that the above-mentioned area is filled with resin, thereby affecting its subsequent sealing and waterproof performance.

[0018] The following are examples and the attached Figure 1-2 , the technical solution of the present invention is further specifically described.

[0019] An LED module structure with improved sealing performance includes a housing 1 for mounting an LED light board 2, wherein a plurality of groups of LED lights 3 are equidistantly arranged on the LED light board 2:

[0020] The housing 1 is provided with a circle of expansion portion 4 at the opening, wherein a rectangular frame 5 is provided inside the expansion portion 4, and a lampshade 6 is provided inside the opening of the rectangular frame 5;

[0021] A circle of rectangular notches 7 are arranged around the outer corner edges of the rectangular frame 5, wherein a screw 8 penetrating through the side wall of the rectangular frame 5 and extending into the rectangular notch 7 is arranged on the side wall of the expansion portion 4, and a nut 9 is screwed to the end of the screw 8, and a limit seat 10 is arranged on one end surface of the nut 9, wherein a U-shaped notch 11 for fixing the electric heating wire 12 is arranged on one end surface of the limit seat 10;

[0022] The inner side wall of the open end of the expansion portion 4 is surrounded by a plurality of strip grooves 13 connected with the rectangular notch 7, wherein the strip grooves 13 and the rectangular notch 7 are both filled with a resin bonding layer 14, and the side wall of the expansion portion 4 is also provided with a plurality of groups of connecting holes (not shown) connected with the strip grooves 13, and sealing plugs (not shown) are provided in the connecting holes.

[0023] In this embodiment, the diameter of the limiting seat 10 is greater than the diameter of the nut 9 , wherein the limiting seat 10 is a truncated cone structure, and the largest diameter end of the limiting seat 10 is fixedly connected to the end face of the nut 9 .

[0024] like Figure 2 As shown, elastic protrusions 15 are provided on both side walls of the U-shaped notch 11 to press against the heating wire 12, wherein a slot for accommodating one end of the elastic protrusion 15 is provided on the side wall of the U-shaped notch 11. During installation, the heating wire 12 presses the protrusion 15 to deform it, so that the heating wire 12 slides into the bottom of the U-shaped notch 11, and then the stretched protrusion 15 clamps the heating wire 12 to prevent it from sliding out, thereby fixing the heating wire 12 so as to facilitate the subsequent easy pouring of resin.

[0025] In this embodiment, a through hole for the screw 8 to pass through is provided on the side wall of the rectangular frame 5, wherein a circle of grooves I (not shown) are provided around the side wall of the rectangular notch 7 outside the through hole, and a rubber sealing ring I (not shown) is provided in the groove I, and the side wall of the nut 9 is pressed against the end face of the sealing ring I. The sealing ring I prevents liquid from flowing into the through hole through the gap between the nut 9 and the side wall of the rectangular notch 7.

[0026] In this embodiment, two groups of grooves II (not shown) are arranged around the side wall of the expansion part 4, wherein the screw 8 is located on the side wall of the expansion part 4 between the two groups of grooves II, and a sealing ring II (not shown) is arranged in the groove II, wherein the side wall of the rectangular frame 5 is pressed against the end face of the sealing ring II. The sealing ring II prevents liquid from seeping into the housing 1 from the gap between the expansion part 4 and the rectangular frame 5.

[0027] In this embodiment, the limiting seat 10 is located in the rectangular notch 7 , and one end of the heating wire 12 extends to the outside of the rectangular frame 5 .

[0028] It should be noted that the present invention is an LED module structure with improved sealing performance, and each component is a universal standard part or a component known to technical personnel in this field, and its structure and principle can be known to technical personnel through technical manuals or through conventional experimental methods.

[0029] When in use, the rectangular frame 5 is placed in the expansion part 4 so that the lampshade 6 seals the opening of the shell 1, and then the LED lamp board 2 is sealed in the shell 1. At this time, the screw 8 passes through the through hole and slides into the rectangular notch 7. Then, the nut 9 is installed on the screw 8 in the rectangular notch 7 to lock and fix it to prevent the expansion part 4 from separating from the rectangular frame 5. The limit seat 10 seals the opening of one end of the nut 9, and the gap between the other end of the nut 9 and the side wall of the rectangular notch 7 is sealed by the sealing ring I to prevent subsequent resin from penetrating into the above-mentioned gap or opening and affecting the subsequent disassembly of the nut 9;

[0030] Next, after inserting the heating wire 12 into the U-shaped notch 11, the module is laid flat with the expansion portion 4 opening facing upwards. At this time, the rectangular notch 7 and the strip groove 13 can be filled with glue through the rectangular notch 7 opening and condensed into a resin bonding layer 14, thereby bonding and fixing the rectangular frame 5 in the expansion portion 4, and sealing the gap between the two, preventing liquid from penetrating into the housing 1 through the gap between the two and contacting the LED light board 2, thereby improving its waterproof safety;

[0031] When the resin bonding layer 14 is formed, the resin bonding layer 14 is hung by the strip groove 13 and the limit seat 10 to prevent it from slipping out of the rectangular notch 7 and the strip groove 13. When the rectangular frame 5 needs to be removed, the heating wire 12 works to melt the resin bonding layer 14 in the rectangular notch 7 so that it can be poured out through the opening of the rectangular notch 7. Finally, the nut 9 is removed to remove the rectangular frame 5 from the expansion part 4 to facilitate disassembly. When the resin bonding layer 14 in the strip groove 13 is melted, the sealing plug can be pulled out to allow the liquid to flow out from the connecting hole. If the resin in the strip groove 13 is not dissolved and the rectangular frame 5 has been removed from the expansion part 4, the resin in the strip groove 13 can be squeezed by inserting a tool through the connecting port to separate it from the side wall of the strip groove 13 and then taken out.

[0032] The present invention uses a nut 9 and a screw 8 to strengthen the connection stability between the expansion part 4 and the rectangular frame 5, and the open rectangular notch 7 at one end has a large opening, so it is convenient to inject glue through it to condense into a resin bonding layer 14 during subsequent sealing. While sealing the gap between the rectangular frame 5 and the expansion part 4, it also improves the connection stability between the two, and the heating wire 12 also facilitates the disassembly work between the rectangular frame 5 and the expansion part 4.

[0033] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
