Description

Technical Field

[0001] This utility model relates to the field of point light source technology, and in particular to an easy-to-maintain LED point light source. Background Technology

[0002] LED point light sources are a new type of decorative lighting, supplementing linear light sources and floodlighting. Once installed, LED point light sources are used for a long time, which may cause individual LEDs to reach the end of their lifespan or other problems that affect their normal use. In order to ensure the overall lighting effect, it is necessary to repair the individual LEDs.

[0003] Currently, the structure of a single LED point light source includes a housing, a lampshade, and a circuit board installed inside the housing. The lampshade is fixed to the housing with screws. During maintenance, tools are needed to disassemble the screws. The screws are small and easily lost, which increases the difficulty of maintenance and causes great inconvenience. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this patent application is how to provide an easy-to-operate, easy-to-use, and easy-to-maintain LED point light source that does not require screws or disassembly tools.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] An easy-to-maintain LED point light source includes several individual LED point light sources connected by wires. Each individual LED point light source includes a housing and a lampshade.

[0007] The outer casing is cylindrical with an opening at one end. Wiring holes are provided on both sides of the outer casing. The outer casing has a mounting cavity for placing a circuit board. Protruding edges are fixedly installed outward at both ends of the outer casing. The lampshade includes a light-transmitting plate and a connecting ring fixedly installed on the outside of the light-transmitting plate. The connecting ring is positioned opposite the protruding edges.

[0008] Both sides of the connecting ring are fixedly installed with insert plates. The insert plates have insertion holes. The insert plates have outwardly protruding limit blocks located above the insertion holes. The protruding edge has a sliding groove that can slide with the insert plates. The protruding edge also has a clearance opening that communicates with the sliding groove. The limit block can pass through the clearance opening and rotate to below the protruding edge. The outer shell has grooves on both sides. The outer shell has spring pieces fixedly installed opposite the grooves that can be inserted with the insertion holes.

[0009] In this way, when a single LED point light source needs repair, the circuit board can be repaired by simply disassembling the lamp cover. When disassembling the lamp cover, press the spring tab inward into the groove, disengaging the spring tab from the socket. Then, push the insert plate to rotate, aligning the limiting block with the clearance opening. The insert plate is then removed from the slide. During reassembly after repair, align the insert plate with the slide and the limiting block with the clearance opening. Then, rotate the connecting ring; the insert plate rotates along the slide, and the limiting block rotates to below the protrusion. Simultaneously, the spring tab engages with the socket, completing the connection. The socket and spring tab design restrict the rotation of the connecting ring, and the limiting block prevents the connecting ring from disengaging from the protrusion.

[0010] The end of the spring piece near the recess has a bevel. This facilitates the spring piece's rapid entry into the socket during the rotation of the connecting ring, with the bevel acting as a guide.

[0011] The outer casing contains a mounting plate, on which an internally threaded cylinder is fixedly mounted. A circuit board is connected to the internally threaded cylinder via screws. The circuit board has several LED beads, and two wires extend outwards from the circuit board through two wire holes. Rubber sleeves are provided between each wire and the wire hole to facilitate circuit board installation. Adjacent LED point light sources are connected via wires.

[0012] The outer side of the outer shell is fixed with several reinforcing ribs, and the two ends of the reinforcing ribs are respectively fixedly connected to the raised edge. This improves the strength of the outer shell.

[0013] The protruding edge away from the lampshade is fixed to a support, and the support has a through-hole. This facilitates the installation of individual LED point light sources in the required positions.

[0014] In summary, this easy-to-maintain LED point light source has the advantages of requiring no screws or disassembly tools, being easy to operate, and convenient to use. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings. In the description of the present invention, it should be understood that directional terms such as "upper," "lower," "top," and "bottom" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. These terms are used only for the convenience of describing the present invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of the present invention. The directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0020] like Figure 1-4 As shown, an easy-to-maintain LED point light source includes several LED point light source units, adjacent LED point light source units are connected by wires, and each LED point light source unit includes a housing 1 and a lampshade.

[0021] The outer casing is cylindrical with an opening at one end. Wiring holes 2 are provided on both sides of the outer casing. The outer casing has a mounting cavity for placing a circuit board. Protruding flanges 3 are fixedly installed outward at both ends of the outer casing. The lampshade includes a light-transmitting plate 4 and a connecting ring 5 fixedly installed on the outside of the light-transmitting plate. The connecting ring is positioned opposite the protruding flange.

[0022] Both sides of the connecting ring are fixedly installed with insert plates 6. The insert plates are provided with insertion ports 7. The insert plates are provided with limiting blocks 8 protruding outward, and the limiting blocks are located above the insertion ports. The protruding edge is provided with a sliding groove 9 that can slide with the insert plates. The protruding edge is also provided with a clearance opening 10 that communicates with the sliding groove. The limiting block can pass through the clearance opening and rotate to below the protruding edge. The outer shell is provided with grooves on both sides. The outer shell is fixedly installed with spring pieces 11 that can be inserted and engaged with the insertion ports, facing the grooves.

[0023] In this way, when a single LED point light source needs repair, the circuit board can be repaired by simply disassembling the lamp cover. When disassembling the lamp cover, press the spring tab inward into the groove, disengaging the spring tab from the socket. Then, push the insert plate to rotate, aligning the limiting block with the clearance opening. The insert plate is then removed from the slide. During reassembly after repair, align the insert plate with the slide and the limiting block with the clearance opening. Then, rotate the connecting ring; the insert plate rotates along the slide, and the limiting block rotates to below the protrusion. Simultaneously, the spring tab engages with the socket, completing the connection. The socket and spring tab design restrict the rotation of the connecting ring, and the limiting block prevents the connecting ring from disengaging from the protrusion.

[0024] A groove is provided between the connecting ring and the raised edge, and a sealing ring is placed in the groove for waterproofing.

[0025] In practice, the end of the spring piece near the recess is provided with a bevel 12. This facilitates the quick entry of the spring piece into the socket during the rotation of the connecting ring, with the bevel acting as a guide.

[0026] In implementation, a mounting plate 13 is fixedly installed inside the housing, and an internally threaded cylinder is fixedly installed on the mounting plate. The circuit board is connected to the internally threaded cylinder by screws. The circuit board has several LED beads, and two wires are connected to the circuit board outwards. The two wires pass through two wire holes, and rubber sleeves are provided between the two wires and the wire holes. This facilitates the installation of the circuit board, and adjacent LED point light sources are connected by wires. The circuit board has an existing structure and is installed inside the housing.

[0027] In practice, several reinforcing ribs 14 are fixed to the outer side of the outer shell, and the two ends of the reinforcing ribs are respectively fixedly connected to the protruding edge. This improves the strength of the outer shell.

[0028] During implementation, a support 15 is fixed outward from the protruding edge away from the lampshade, and a mounting hole is provided through the support. This facilitates the installation of individual LED point light sources in the required positions.

[0029] Finally, it should be noted that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims and their equivalents, this utility model also intends to include these modifications and variations.
