A rectangular support platform 24 is provided on the outer ring of the upper part of the adapter seat 2, and four supporting columns 25 are erected on the supporting platform 24. The light source board 3 is a circuit board with LED lamp beads or patches, and the light source board 3 is filled and sealed. A first terminal 31 is exposed on the bottom surface of the light source board 3, and the number of pins of the first terminal 31 corresponds to the connection hole. The light source board 3 is placed on the adapter seat 2 and supported by the supporting column 25, and the first terminal 31 is embedded in the sink 22 at the upper end of the adapter seat 2, and the pin of the first terminal 31 extends into the connection hole and plugs into the upper end of the adapter electrode 23.

[0038] The supporting platform 24 is symmetrically provided with first buckles 26 on both sides. The first buckles 26 are ear-shaped and have a snap-on hole. The light-transmitting cover 4 includes an arc-shaped light-transmitting plate 41 and a frame 42 with a rectangular cross-section. The light-transmitting plate 41 is on the frame 42 and the outer edge of the light-transmitting plate 41 extends outward. A limiting ring 43 is provided on the inner side of the frame 42, and first buckle protrusions 44 are provided on both sides of the outer wall of the frame 42 corresponding to the first buckle 26. During installation, the light-transmitting cover 4 is placed on the light source board 3, and the first buckle protrusion 44 is buckled and fixed with the snap-on hole of the first buckle 26 by pressing. At this time, the limiting ring 43 abuts against the edge of the light source board 3 to suppress it.

[0039] The base 1 is provided with a wire hole in the horizontal direction and a connecting sleeve 11 in the vertical direction, and the connecting sleeve 11 is connected with the wire hole. The base 1 is formed by connecting an upper shell 1A and a lower shell 1B (by existing methods such as buckling and bonding), and the connecting sleeve 11 is arranged on the upper shell 1A, and the wire hole is formed by splicing the installation grooves of the upper shell 1A and the lower shell 1B. A cable 5 is passed through the wire hole, and a circuit board 6 is arranged on the cable 5. The wire core of the cable 5 is welded and fixed to the contact electrode 61 on the bottom surface of the circuit board 6. A second terminal 62 is provided on the top surface of the circuit board 6, and the number of pins of the second terminal 62 corresponds to the number of pins of the first terminal 31. The lower part of the adapter 2 is provided with a waterproof rubber sleeve 27. When installed, the lower part of the adapter 2 is embedded in the connecting sleeve 11, and the pin of the second terminal 62 extends into the connecting hole and plugs into the lower end of the adapter electrode 23. The upper and lower ends of the transfer electrode 23 are provided with plug holes corresponding to the pins of the first terminal 31 and the pins of the second terminal 62 , and the first terminal 31 and the second terminal 62 are electrically connected through the transfer electrode 23 .

[0040] The side wall of the connecting sleeve 11 extends upward with two symmetrical second buckles 12, which are ear-shaped and have a snap-on hole. The frame 42 of the light-transmitting cover 4 is symmetrically provided with second buckle protrusions 45 on both sides, and the first buckle protrusion 44 and the second buckle protrusion 45 are provided on different sides. During installation, the lower part of the adapter 2 is embedded in the connecting sleeve 11, and the light-transmitting cover 4 is pressed down to make the second buckle protrusion 45 fall into the snap-on hole of the second buckle 12 and snap-on it. At this time, the light-transmitting cover 4 can tighten the connecting sleeve 11, so that it is in closer contact with the waterproof rubber sleeve 27.

[0041] There are multiple pixel lamp units, which are connected in series by the cable 5. The shell 7 is in the shape of a long strip, and multiple pixel lamp units are installed in a shell 7. The base 1 is provided with a guide protrusion 13, and the guide protrusion 13 extends horizontally outward on both sides of the base 1. The inner wall of the shell 7 is provided with a guide groove 72, and the top is provided with a mounting hole 71. The number of mounting holes 71 corresponds to the number of pixel lamp units. The base 1 is installed in the shell 7 and the guide protrusion 13 is inserted into the guide groove 72 and slides with the guide groove 62. The shell 7 includes an inner layer 7A and an outer layer 7B. The outer layer 7B is a copper tube that is punched after integral molding. The inner layer 7A is a profile with the guide groove 72. The outer wall of the inner layer 7A is in close contact with the inner wall of the outer layer 7B.

[0042] During production and installation, a. first weld the circuit board 6 and the cable 5, and then place them in the installation groove of the lower shell 1B of the base 1, cover the upper shell 1B and fix it, and the second terminal 62 of the circuit board 6 is in the connecting sleeve 12 of the base 1. b. After the base 1 of multiple pixel lamp units is connected to the cable 5, insert the guide protrusion 13 of the base 1 along the guide groove 72 port of the outer shell 7, push and slide into the inner shell 7 until the base 1 of the entire string of pixel lamps is placed in the outer shell 7, and install it quickly and conveniently through the sliding cooperation of the guide groove 72 and the guide protrusion 13. c. Place the light source board 3 on the adapter 2, and the first terminal 31 is inserted into the upper end of the adapter electrode 23; the light-transmitting cover 4 is covered on the light source board 3, and force is pressed to make the first buckle protrusion 44 buckle with the first buckle 26, and then the light source assembly is formed by filling and sealing. d. Then, extend the light source assembly into the outer shell 7 through the mounting hole 71 on the outer shell 7, as shown Figure 8 As shown, after the adapter 2 enters the housing 7, the lower part of the adapter 2 is embedded in the connecting sleeve 12, the second terminal 62 is plugged with the lower end of the adapter electrode 23, and then the light-transmitting cover 4 is pressed to make the second buckle protrusion 45 fall into the buckle hole of the second buckle 12 and buckle with it. Since the outer diameter of the light-transmitting plate 41 is larger than the installation hole, at this time, the outer edge bottom side of the light-transmitting plate 41 is tightly attached to the outer side of the housing 7. e. The two ends of the housing 7 are blocked by the end covers. After installation, the structure of the pixel lamp monomer is stable and will not deviate, and the power supply of the light source board 3 is stable.

[0043] The light-transmitting cover 4 is provided with two grooves 46. When it needs to be disassembled for maintenance, the light-transmitting cover can be disassembled by inserting a tool into the grooves 46, clamping the light-transmitting cover and pulling it up. The adapter 2 will not be pulled out synchronously because the first buckles 26 on both sides abut against the housing 7. The light source board 3 is plugged into the adapter 2 and can be disassembled by pulling it up when it needs to be replaced. The operation is simple, convenient and fast, which significantly saves maintenance time.

[0044] The pixel lamp structure of the present invention is also applicable to lamp types such as linear lamps, wall washers, and low-position lighting lamps composed of multiple pixel lamp units and a housing.

[0045] The above-mentioned preferred implementation modes should be regarded as illustrative examples of the implementation modes of the present application scheme. Any technical deductions, replacements, improvements, etc. that are identical or similar to the present application scheme or made based on this scheme should be regarded as within the scope of protection of this patent.
