The substrate is provided with a plurality of light emitting units 230 along the length direction, and a packaging glue 240 for packaging the light emitting units 230 is fixed outside the light emitting units 230, and the packaging glue 240 is provided along the length direction of the substrate. The waterproof sleeve 400 is sleeved outside the substrate and the light strip connector 300 to enhance the waterproof performance of the COB light strip 1000.

[0033] In this embodiment, two adjacent substrates are defined as a first substrate 210 and a second substrate 220, and the first end of the first substrate 210 and the second end of the second substrate 220 are connected to each other through a light strip connector 300. The waterproof sleeve 400 includes a first light tube segment 410, a second light tube segment 420 and a connecting tube segment 430. The first light tube segment 410 and the second light tube segment 420 are both made of transparent silicone material to ensure the light-emitting effect of the light-emitting element on the substrate when waterproof. At the same time, the silicone sleeve is flexible and convenient for bending the light tube segment. The first light tube segment 410 is sleeved outside the first substrate 210, the second light tube segment 420 is sleeved outside the second substrate 220, and the connecting tube segment 430 is sleeved outside the light strip connector 300.

[0034] It should be noted that the first substrate 210 and the second substrate 220 are defined here only for the convenience of description, and are not limited to being the first substrate 210 or the second substrate 220, nor are they limited to two substrates. It should be understood that the number of substrates can be any number greater than or equal to two, and two adjacent substrates are waterproofed by a set of waterproof sleeves 400.

[0035] Reference Figures 1 to 3 The light strip connector 300 includes a first connector 310 and a second connector 320. The first connector 310 is fixed to the first substrate 210, and the second connector 320 is fixed to the second substrate 220.

When the first connector 310 and the second connector 320 are plugged and matched, the anti-drop buckle 321 is inserted into the card slot 311 and snap-fitted with the card slot 311, thereby preventing the first connector 310 from being detached from the second connector 320 during use.

[0037] Reference Figures 1 to 3The connecting pipe section 430 includes a first connecting pipe 431 and a second connecting pipe 432. The first connecting pipe 431 and the second connecting pipe 432 are both made of hard materials to facilitate the connection and sealing of the first connecting pipe 431 and the second connecting pipe 432. The first connecting pipe 431 is connected to the first lamp tube section 410, and the second connecting pipe 432 is connected to the second lamp tube section 420. The first pipe section and the second pipe section are arranged opposite to each other, and the facing end surfaces of the first connecting pipe 431 and the second connecting pipe 432 are parallel to each other. A sealing gasket 433 is abutted between the facing end surfaces of the first connecting pipe 431 and the second connecting pipe 432, and the first connecting pipe 431 and the second connecting pipe 432 are fastened and connected by a connecting piece 434. Thus, the separately arranged first pipe section and the second pipe section facilitate the connection of the COB light strip 1000 at the light strip joint 300. After the COB light strip 1000 is connected, the first connecting tube 431 and the second connecting tube 432 are fastened and connected, and the gap at the connection between the first connecting tube 431 and the second connecting tube 432 is sealed by the sealing gasket 433 to ensure the water tightness of the connection of the COB light strip 1000.

The first connecting portion 4311 and the second connecting portion 4321 are arranged facing each other, and the connecting member 434 is fastened between the first connecting portion 4311 and the second connecting portion 4321. The first connecting portion 4311 protrudes from the outer circumference of the first connecting tube 431, and the second connecting portion 4321 protrudes from the outer circumference of the second connecting tube 432, so that the connecting member 434 can connect the first connecting tube 431 and the second connecting tube 432 conveniently.

[0039] Reference Figures 3 to 5 In this embodiment, the outer circumference of the first connection part 4311 is a cylindrical surface, and an external thread is provided on the circumference of the first connection part 4311. The connecting member 434 is cylindrical, and the connecting member 434 is rotatably sleeved on the second connection part 4321, and the inner circumference of the connecting member 434 is provided with an internal thread that matches the thread of the first connection part 4311.

[0040] The outer circumference of the second connection part 4321 is a cylindrical surface, and an annular step groove 4322 is provided on the circumference of one end of the second connection part 4321 away from the first connection part 4311. The connection member 434 is provided with an annular protrusion 4341 protruding inwardly to cooperate with the annular step groove 4322. The connection member 434 is blocked by the second connection part 4321 in the axial direction through the cooperation between the annular step groove 4322 and the annular protrusion 4341. Therefore, when connecting the first connection part 4311 and the second connection part 4321, the ends of the first connection pipe 431 and the second connection pipe 432 are aligned, and the connection member 434 is rotated, and the internal thread of the connection member 434 cooperates with the external thread of the first connection part 4311, and the annular step groove 4322 blocks the protrusion, so that the connection member 434 locks the first connection part 4311 and the second connection part 4321. This connection method is simple and reliable, is not easy to affect the connection pipe section 430, and is conducive to improving the water tightness of the connection pipe section 430. In addition, in other embodiments, other methods such as screws, buckles or clamps may be used to connect the first connecting pipe 431 and the second connecting pipe 432.

Both the first stopper 4312 and the second stopper 4323 are rectangular stoppers to fit the tube openings of the first connecting tube 431 and the second connecting tube 432. The first stopper 4312 matches the second stopper 4323, and a sealing ring 435 is abutted between the first stopper 4312 and the second stopper 4323.

[0042] In this embodiment, the first stop 4312 protrudes from the end of the first connecting tube 431, and the second stop 4323 is recessed relative to the end of the second connecting tube 432, that is, the first stop 4312 is a male stop, and the second stop 4323 is a female stop. The first stop 4312 is inserted into the end of the second connecting tube 432 and cooperates with the second stop 4323.

[0043] A positioning ring 4313 is provided at one end of the first stop 4312 facing the second connection pipe 432. The positioning ring 4313 is a square ring that fits with the inner cavity of the second connection pipe 432. When the first connection pipe 431 and the second connection pipe 432 are matched, the positioning ring 4313 is inserted into the second connection pipe 432, so that the first connection pipe 431 and the second connection pipe 432 are more closely matched. Among them, the sealing ring 435 is sleeved on the outer peripheral side of the positioning ring 4313 and is located at the first stop 4312. After the positioning ring 4313 is inserted into the second connection pipe 432, the sealing ring 435 is tightly pressed between the first stop 4312 and the second stop 4323. The setting of the positioning ring 4313 facilitates the installation of the sealing ring 435.

[0046] In this embodiment, the first connecting tube 431 is integrally formed with the first lamp tube segment 410 , and the second connecting tube 432 is integrally formed with the second lamp tube segment 420 to ensure water tightness between the first lamp tube segment 410 and the first connecting tube 431 and between the second lamp tube segment 420 and the second connecting tube 432 .
