[0022] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0023] The embodiment of the present application solves the problem that existing LED lamp beads are difficult to install and inconvenient to disassemble and replace later by providing a plug-in LED lamp bead.

[0024] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0025] The embodiment of the utility model discloses a pluggable LED lamp bead.

[0026] According to the attached Figure 1-5 As shown, it includes a lamp bead head 1 and a connecting conductor 3. A plug-in pin 2 is fixedly installed at the bottom of the lamp bead head 1. The plug-in pin 2 includes a metal conductor 21 and an anti-dropping clamp 22 integrally formed on the outer surface of the metal conductor 21.

[0027] A slot is provided on the connecting conductor 3, and the anti-slip clamp 22 is movably engaged with the slot. A receiving slot 23 is provided on the outer surface of the plug-in pin 2, and the anti-slip clamp 22 is arranged inside the receiving slot 23. The outer end of the anti-slip clamp 22 faces the lamp bead head 1, and the end of the anti-slip clamp 22 is bent toward the side away from the receiving slot 23.

[0028] The lamp bead head 1 includes a light-emitting part 11 and a packaging contact pad 12 integrally formed on the lower surface of the light-emitting part 11. An insulation ring 13 is fixedly provided on the lower surface of the packaging contact pad 12. A positioning protrusion 14 is fixedly provided on the bottom of the insulation ring 13. The top of the metal conductor 21 extends into the interior of the light-emitting part 11.

[0029] By setting a plug-in pin 2 at the bottom of the lamp bead head 1 and modifying the connecting conductor 3 used for parallel installation of multiple lamp bead heads 1, the anti-dropping clamp 22 on the plug-in pin 2 is clamped in the slot on the connecting conductor 3 to achieve plug-in installation. No welding is required, and the installation speed is fast. When replacing later, the end of the anti-dropping clamp 22 can be pushed into the storage slot 23 to pull the lamp bead head 1 out from the connecting conductor 3, which is convenient for replacement. Example

[0030] The metal conductor 21 is a long deformed metal 211 , and the receiving groove 23 is formed at the bottom of the long deformed metal 211 .

[0031] The slot is a semi-open slot 31 , which is opened on one side of the lower surface of the connecting conductor 3 . The long deformed metal strip 211 is movably inserted under the connecting conductor 3 , and the long deformed metal strip 211 is in close contact with the lower surface of the connecting conductor 3 .

[0032] In this embodiment, the long deformed metal 211 is inserted from one side of the connecting conductor 3 to the bottom of the connecting conductor 3, and the insertion direction is opposite to the opening direction of the semi-open groove 31. When the long deformed metal 211 enters under the connecting conductor 3, the end of the anti-slip clamp 22 is squeezed and pushed into the receiving groove 23. As the long deformed metal 211 continues to penetrate deeper, when the anti-slip clamp 22 is opposite to the semi-open groove 31, the end of the anti-slip clamp 22 automatically pops out from the receiving groove 23, so that the end of the anti-slip clamp 22 is against the inner wall of the semi-open groove 31, so that the long deformed metal 211 cannot be pulled out. At the same time, the long deformed metal 211 is in close contact with the lower surface of the connecting conductor 3, thereby achieving power supply. This solution is suitable for use when the thickness requirements of the lamp are relatively strict. The back of the connecting conductor 3 needs to be close to the insulating part, which can effectively reduce the installation height of the lamp bead, thereby achieving an ultra-thin effect. When replacing the lamp bead, the connecting conductor 3 needs to be removed. Example

[0033] The metal conductor 21 is a short memory metal strip 212 , and the receiving slot 23 is defined in the middle of the short memory metal strip 212 .

[0034] The card slot is a through slot 32 , the short memory metal strip 212 is movably inserted into the through slot 32 , and the short memory metal strip 212 is tightly attached to the inner wall of the through slot 32 , and the anti-dropping card 22 is movably engaged with the bottom of the through slot 32 .

[0035] In this solution, the short strip of memory metal 212 is directly inserted downward perpendicular to the through groove 32. When the anti-slipping card 22 is located inside the through groove 32, it is squeezed laterally, causing the anti-slipping card 22 to automatically enter the receiving groove 23. When the end of the anti-slipping card 22 is located below the through groove 32, the anti-slipping card 22 is moved out of the receiving groove 23 and abuts against the bottom of the through groove 32, thereby fixing the lamp bead head 1. At this time, the short strip of memory metal 212 fits the inner wall of the through groove 32 to achieve power supply. This solution is suitable for use in situations where there is no requirement for the thickness of the lamp. The connecting conductor 3 can be installed in the air. When replacing the lamp bead head 1, the anti-slipping card 22 can be pressed into the receiving groove 23 by the rear side of the connecting conductor 3, making disassembly and assembly easier. At the same time, the short strip of memory metal 212 does not need to be bent, reducing the risk of damage during installation.

[0036] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention.
