Description

Technical Field

[0001] This utility model relates to the technical field of LED light strips, and in particular to an assembled LED light strip with a heat sink. Background Technology

[0002] LED lights, or light-emitting diodes, are solid-state semiconductor devices that can convert electrical energy into visible light. They can directly convert electricity into light. The heart of an LED is a semiconductor chip. One end of the chip is attached to a support, which is the negative electrode, and the other end is connected to the positive electrode of the power supply. The entire chip is encapsulated in epoxy resin.

[0003] Currently, existing modular LED light strips are generally connected by snap-fit ​​joints. As a result, the two connected light strips are usually fixed in place, and the angle of the other end of the light strip cannot be adjusted, making them rather rigid to use. Therefore, we have designed a modular LED light strip with a heat sink, which allows the angle of the connection between the two LED light strips to be adjusted, enabling them to be connected more flexibly and adapt to different environments. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a modular LED light strip with a heat sink.

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

[0006] A modular LED light strip with a heat sink includes: a housing, wherein the central cavity of the housing is an open structure, and a circuit board is disposed in the opening, wherein a plurality of LED lights are disposed at equal intervals on the circuit board, and a protective base plate is disposed on the circuit board; a connecting groove and a connecting post are respectively disposed in the center of the left and right sides of the housing, and conductive posts are disposed on the inner walls of the housing on both sides of the connecting groove, and a movable plug is fixedly sleeved on the side of the connecting post away from the housing, the connecting post and the housing are rotatably connected by a bearing, and a metal conductive block is disposed on the side of the connecting post in the inner cavity of the movable plug; semi-circular slots are opened on the housing on both sides of the movable plug, and the shape and size of the side of the movable plug matches the shape and size of the side of the connecting groove.

[0007] In one embodiment, the two conductive posts are arranged in a mirror image with respect to the connecting groove. The conductive posts extend into the inner cavity of the housing, and wires are electrically connected to the posts located inside the housing. The wires are electrically connected to the circuit board.

[0008] In one embodiment, the diameter of the side of the semi-circular slot matches the diameter of the side of the conductive post, and the side of the metal conductive block is semi-circular in shape and abuts against the inner wall of the semi-circular slot, with the diameter of its side being the same as that of the side of the semi-circular slot.

[0009] In one embodiment, the connecting post includes two semicircular plates connected together by a plastic connector, and the metal conductive blocks are respectively disposed on the plates of the semicircular plates.

[0010] In one embodiment, the side of the semicircular plate closest to the outer casing is electrically connected to the wire, the wire is electrically connected to the circuit board, and the wire length between the wire and the circuit board is redundantly designed.

[0011] In one embodiment, a heat sink is provided at the bottom of the housing, the heat sink is located at the bottom of the circuit board, and a plurality of heat dissipation holes are provided at equal intervals along the horizontal and vertical directions at the bottom of the housing.

[0014] Compared with the prior art, the present invention has at least the following advantages:

[0015] This utility model discloses a modular LED light strip with a heat sink. Through the connection groove designed on the outer shell and the conductive post designed in the groove, and the movable plug designed on the other side, the shape and size design of the movable plug and the connection groove, as well as the semi-circular slot design, allow the movable plug to be locked in the connection groove. Furthermore, through the rotatable connection between the movable plug and the outer shell via a bearing, and the engagement between the semi-circular slot and the conductive post, the LED light strip at the connection point can be rotated and adjusted to a certain extent in terms of vertical angle.

Detailed Implementation

[0024] 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.

[0025] like Figure 1-5As shown, a modular LED light strip with a heat sink includes: a housing 1, the inner cavity of the housing 1 being an open structure, wherein a circuit board 15 is provided in the opening, and a plurality of LED lights 4 are equally spaced on the circuit board 15, and a protective base plate 11 is provided on the circuit board 15; a connecting groove 12 and a connecting post 3 are respectively provided in the center of the left and right sides of the housing 1; conductive posts 13 are provided on the inner walls of the housing 1 on both sides of the groove 12; a movable plug 2 is fixedly sleeved on the side of the connecting post 3 away from the housing 1; the connecting post 3 and the housing 1 are rotatably connected by a bearing; a metal conductive block 33 is provided on the side of the connecting post 3 in the inner cavity of the movable plug 2; semi-circular slots 21 are opened on the housings on both sides of the movable plug 2, and the shape and size of the side of the movable plug 2 matches the shape and size of the side of the connecting groove 12.

[0026] It should be noted that when workers need to connect multiple LED light strips together (dividing two LED light strips into A and B), they only need to engage the movable plug 2 on A with the connecting groove 12 on B (so that the movable plug 2 on A is inserted into the connecting groove 21 from top to bottom). Therefore, after the engagement is completed, the metal conductive plug 33 will hook onto the conductive post 13, which not only enables mutual connection but also allows the connection position to have a certain degree of rotation. At the same time, the connecting post 3 and the outer shell 1 are connected by a bearing, and the wire 14 and the circuit board 15 are electrically connected. With a redundant design, after the movable plug 2 of A is engaged with the connecting groove 12 of B, the outer shell of A can rotate to a certain extent without affecting the connection. At the same time, a current path can be formed between A and B.

[0027] like Figure 1-2 As shown in one embodiment, two conductive posts 13 are arranged in a mirror image with the connecting groove 12 as the center. The conductive posts 13 extend into the inner cavity of the outer shell 1, and wires 14 are electrically connected to the posts located inside the shell. The wires 14 are electrically connected to the circuit board 15. The side of the semicircular plate 31 near the outer shell 1 is electrically connected to the wires 14, and the wires 14 are electrically connected to the circuit board 15. The wire length between the wires 14 and the circuit board 15 is redundant. It should be noted that this design allows both the conductive posts 13 and the semicircular plate 31 to form a current path with the circuit board 15, so multiple LED light strips can be electrically connected to each other and thus connected in series.

[0028] like Figure 1 and 4As shown, in one embodiment, the diameter of the side of the semi-circular slot 21 matches the diameter of the side of the conductive post 13. The side of the metal conductive block 33 is semi-circular and abuts against the inner wall of the semi-circular slot 21, and its side diameter is the same as that of the side of the semi-circular slot 21. It should be noted that this design allows the movable insert 2 to be engaged with the conductive post 12, so the metal conductive block 33 can also be engaged with the conductive post 12. The movable insert 2 is made of insulating plastic.

[0029] like Figure 2-5 As shown in one embodiment, the connecting post 3 includes two semicircular plates 31, which are connected together by a plastic connector 32. Metal conductive blocks 33 are respectively disposed on the plates 31. It should be noted that this design allows the two semicircular plates 31 to form independent current paths without conducting current to each other.

[0030] like Figure 3-4 As shown in one embodiment, a heat sink 16 is provided at the bottom of the housing 1. The heat sink 16 is located at the bottom of the circuit board 15. A plurality of heat dissipation holes 17 are equally spaced along the horizontal and vertical directions at the bottom of the housing 1. LED lights 4 are arranged at equal horizontal distances on the circuit board 15. A slot corresponding to each LED light 4 is provided on the protective base plate 11.

[0031] like Figure 3-4 As shown in one embodiment, the bottom of the movable insert 2 is designed to open, and a hinge is provided on the inner wall of the side near the outer shell 1. A rotating sealing plate 22 is provided at one end of the hinge. The shape and size of the rotating sealing plate 22 in top view match the shape and size of the movable insert 2 in top view. An insert plate 23, which connects to the bottom of the housing of the movable insert 2, is provided in the center of the side of the rotating sealing plate 2 away from the hinge. It should be noted that the rotating sealing plate 22 is made of insulating plastic, and it needs to be opened before the two LED light strips are engaged. The sealing is then performed after engagement to prevent the connection from breaking.

[0032] 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.
