[0023] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0024] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 , Fig. 9As shown, it is a structural diagram of an LED lamp group structure provided by an embodiment of the present invention, comprising a base plate 1, wherein the bottom wall of the base plate 1 is provided with a plurality of groups of evenly distributed LED wicks 11, the left and right sides of the base plate 1 are respectively provided with positioning grooves 12, the front and rear ends of the base plate 1 are respectively provided with end plates 2, a cylindrical protective cover 3 is rotatably installed on the outer side of the base plate 1, the protective cover 3 passes through two groups of positioning grooves 12, and an opening 31 is opened on the surface of the protective cover 3, a dual-axis motor 4 is fixedly installed on the top wall of the base plate 1, and the output shafts at both ends of the dual-axis motor 4 are respectively fixedly installed with rotating columns 41, and a dust removal mechanism 5 that cooperates with the LED wicks 11 is provided on the surface of the base plate 1, and the dust removal mechanism 5 includes a brush 51, a support assembly 52, a rotation assembly 53 and a transverse movement assembly 54, the support assembly 52 is located between the two groups of end plates 2 and is connected to the brush 51, and the support assembly The component 52 is used to control the brush 51 to be at the bottom wall of the base plate 1. The transverse movement component 54 is located on the top wall of the base plate 1 and is connected to the support component 52. The transverse movement component 54 controls the brush 51 to reciprocate in the horizontal direction below the LED wick 11 by cooperating with the support component 52. The rotation component 53 is connected to the support component 52. The rotation component 53 controls the brush 51 to move horizontally and rotate synchronously in the vertical plane by cooperating with the support component 52. The top wall of the base plate 1 is provided with a positioning mechanism 6 that cooperates with the protective cover 3. The positioning mechanism 6 includes a rotating component 61 and a driving component 62. The rotating component 61 is located on the top wall of the base plate 1 and is connected to the protective cover 3. The driving component 62 is connected to the rotating component 61. The driving component 62 controls the protective cover 3 to rotate on the outside of the base plate 1 by cooperating with the rotating component 61.

[0026] The bottom plate 1 cooperates with the positioning groove 12 to support and position the protective cover 3. When the lamp set is not in use, the opening 31 on the surface of the protective cover 3 is located above the bottom plate 1. At this time, the protective cover 3 cooperates with the two sets of end plates 2 to seal and protect the LED wick 11 on the bottom wall of the bottom plate 1, effectively preventing dust in the air from adhering to the surface of the LED wick 11. When the lamp set is used for lighting, the dual-axis motor 4 drives the rotating column 41 to rotate, and the driving component 62 cooperates with the rotating component 61 to drive the protective cover 3 to rotate 180 degrees on the surface of the bottom plate 1. The opening 31 on the surface of the protective cover 3 rotates to the bottom of the bottom plate 1. When the LED wick 11 is illuminated, light passes through the opening 31, which can effectively improve the brightness of the lighting. The support component 52 supports and positions the brush 51 at the bottom wall of the base plate 1. Initially, the brush 51 is located on one side of the LED wick 11. When the dual-axis motor 4 drives the rotating column 41 to rotate, the transverse movement component 54 cooperates with the support component 52 to control the brush 51 to move from under the base plate 1 to the other side of the LED wick 11. When the brush 51 is translated, the rotation component 53 cooperates with the support component 52 to control the brush 51 to rotate under the LED wick 11. When the brush 51 rotates, the dust and impurities attached to the surface of the LED wick 11 can be efficiently cleaned, thereby effectively improving the use effect of the LED wick 11.

[0027] like Figure 5 , Figure 8 , Fig. 9 As shown, as a preferred embodiment of the present invention, the support assembly 52 includes two groups of guide grooves 521 respectively opened on the two side walls opposite to each other of the end plates 2, and arc structures are arranged at both ends of the guide grooves 521. The bottom wall of the bottom plate 1 is provided with two groups of relatively distributed receiving grooves 522, and the two ends of the receiving grooves 522 are respectively connected with the guide grooves 521 on the surface of the end plates 2. A sliding block 523 is slidably installed in the guide groove 521, and a cleaning rod 524 is rotatably installed on the two groups of sliding blocks 523, and a plurality of groups of brushes 51 are evenly distributed on the surface of the cleaning rod 524.

[0028] The guide groove 521 supports and positions the sliding block 523, and the transverse movement assembly 54 pulls and positions the sliding block 523 in the guide groove 521. Initially, the sliding block 523 is located at one end of the guide groove 521. The two sets of sliding blocks 523 support and position the cleaning rod 524. Initially, the cleaning rod 524 and the brush 51 are in the storage groove 522. When the dual-axis motor 4 drives the rotating column 41 to rotate, the transverse movement assembly 54 applies a pulling force to the sliding block 523, so that the sliding block 523 moves toward the other end in the guide groove 521. The sliding blocks 523 on both sides cooperate with each other to drive the cleaning rod 524 to translate synchronously under the LED wick 11, and the cleaning rod 524 drives the brush 51 to move synchronously. The self-rotation assembly 53 drives the cleaning rod 524 to rotate while translating, and the cleaning rod 524 drives the brush 51 to rotate synchronously. The brush 51 can efficiently clean the dust and impurities attached to the surface of the LED wick 11.

[0029] like Figure 1 , Figure 7 , Figure 8 , Fig. 9 As shown, as a preferred embodiment of the present invention, the transverse movement assembly 54 includes two groups of relatively distributed wire grooves 541 opened downwardly from the top wall of the end plate 2, and the two groups of wire grooves 541 are respectively connected to the two ends of the guide groove 521, and a first winding roller 542 is fixedly installed on the surface of the rotating column 41, and a second winding roller 543 located on the outer side of the first winding roller 542 is fixedly installed on the surface of the rotating column 41, a first pulling rope 544 is wound on the surface of the first winding roller 542, and a second pulling rope 545 is wound on the surface of the second winding roller 543, and the winding directions of the first pulling rope 544 and the second pulling rope 545 are opposite, and one end of the first pulling rope 544 away from the first winding roller 542 passes through a group of wire grooves 541 to extend into the guide groove 521 and is connected to one side of the sliding block 523, and one end of the second pulling rope 545 away from the second winding roller 543 passes through another group of wire grooves 541 to extend into the guide groove 521 and is connected to the other side of the sliding block 523.

[0030] The double-axis motor 4 drives the rotating column 41 to rotate, and the rotating column 41 drives the first winding roller 542 and the second winding roller 543 to rotate synchronously, the first winding roller 542 unwinds the first traction rope 544, and the second winding roller 543 rewinds the second traction rope 545. During the rewinding process, the second traction rope 545 pulls the sliding block 523 to move in the guide groove 521. When the sliding block 523 moves to the other end of the guide groove 521, the double-axis motor 4 stops rotating. When restarting, the double-axis motor 4 drives the rotating column 41 to rotate in the opposite direction. At this time, the first winding roller 542 rewinds the first traction rope 544, and the second winding roller 543 unwinds the second traction rope 545. During the rewinding process, the first traction rope 544 pulls the sliding block 523 to move to the other side in the guide groove 521.

[0031] like Figure 5 , Figure 8 , Fig. 9 As shown, as a preferred embodiment of the present invention, the self-rotating assembly 53 includes a fixed toothed disc 531 fixedly mounted on the surface of the cleaning rod 524, and a rack 532 located on the outside of the guide groove 521 is fixedly mounted on the side wall of the end plate 2, and the fixed toothed disc 531 is meshed with the rack 532.

[0032] When the cleaning rod 524 translates under the LED wick 11, it drives the fixed toothed disc 531 to move synchronously. The fixed toothed disc 531 rolls along the surface of the rack 532. The fixed toothed disc 531 drives the cleaning rod 524 to rotate while translating. The cleaning rod 524 drives the brush 51 to rotate synchronously. The brush 51 can efficiently clean the dust and impurities attached to the surface of the LED wick 11.

[0033] like Figure 1 , Figure 5 , Figure 6 As shown, as a preferred embodiment of the present invention, the rotating assembly 61 includes an annular gear ring 611 opened on the inner wall of the protective cover 3, and two groups of relatively distributed vertical plates 612 are fixedly installed on the top wall of the bottom plate 1, and the two groups of vertical plates 612 are jointly rotatably installed with a horizontal column 613, and a positioning toothed disc 614 is fixedly installed on the surface of the horizontal column 613, and the positioning toothed disc 614 is meshingly connected with the gear ring 611.

[0034] When in use, the dual-axis motor 4 drives the rotating column 41 to rotate, the driving assembly 62 controls the horizontal column 613 to rotate between the two sets of vertical plates 612, the horizontal column 613 drives the positioning gear plate 614 to rotate synchronously, the positioning gear plate 614 and the gear ring 611 are meshed and driven, and the protective cover 3 can be driven to rotate on the surface of the bottom plate 1. After the protective cover 3 rotates 180 degrees, the dual-axis motor 4 stops running, and the driving assembly 62 stops running synchronously at this time. Then, the position of the opening 31 on the surface of the protective cover 3 can be conveniently adjusted.

[0035] like Figure 1 , Figure 5 , Figure 6 As shown, as a preferred embodiment of the present invention, the driving assembly 62 includes synchronous toothed discs 621 fixedly mounted on the surfaces of the rotating column 41 and the horizontal column 613 respectively, and the two sets of synchronous toothed discs 621 are commonly connected with a synchronous belt 622.

[0036] The dual-axis motor 4 drives the rotating column 41 to rotate, and the rotating column 41 drives the synchronous gear plate 621 to rotate. The two sets of synchronous gear plates 621 cooperate with the synchronous belt 622 to drive the horizontal column 613 to rotate synchronously.

[0037] like Figure 1 , Figure 7As shown, as a preferred embodiment of the present invention, the top wall of the bottom plate 1 is fixedly mounted with a side plate 7, and the side plate 7 is rotatably connected to the rotating column 41. The side plate 7 can effectively improve the stability of the rotating column 41 during rotation.

[0038] The working principle of the present invention is: the base plate 1 and the positioning groove 12 cooperate with each other to support and position the protective cover 3. When the lamp group is not in use, the opening 31 on the surface of the protective cover 3 is located above the base plate 1. At this time, the protective cover 3 cooperates with the two groups of end plates 2 to seal and protect the LED wick 11 on the bottom wall of the base plate 1, effectively preventing dust in the air from adhering to the surface of the LED wick 11.

[0039] When in use, the dual-axis motor 4 drives the rotating column 41 to rotate, and the rotating column 41 drives the synchronous toothed disc 621 to rotate. The two sets of synchronous toothed discs 621 cooperate with the synchronous belt 622 to drive the horizontal column 613 to rotate synchronously. The horizontal column 613 drives the positioning toothed disc 614 to rotate synchronously, and the positioning toothed disc 614 and the gear ring 611 are meshed and driven to drive the protective cover 3 to rotate on the surface of the bottom plate 1. After the protective cover 3 rotates 180 degrees, the dual-axis motor 4 stops running, and the opening 31 on the surface of the protective cover 3 rotates to the bottom of the bottom plate 1. When the LED lamp core 11 is illuminated, the light passes through the opening 31, which can effectively improve the brightness of the lighting.

[0040] The rotating column 41 drives the first winding roller 542 and the second winding roller 543 to rotate synchronously. The first winding roller 542 unwinds the first pulling rope 544, and the second winding roller 543 rewinds the second pulling rope 545. The second pulling rope 545 pulls the sliding block 523 to move in the guide groove 521 during the rewinding process. When the sliding block 523 moves to the other end of the guide groove 521, the dual-axis motor 4 stops rotating. When the cleaning rod 524 translates under the LED wick 11, it drives the fixed toothed disc 531 to move synchronously. The fixed toothed disc 531 rolls along the surface of the rack 532. The fixed toothed disc 531 drives the cleaning rod 524 to rotate while translating. The cleaning rod 524 drives the brush 51 to rotate synchronously. The brush 51 can efficiently clean the dust and impurities attached to the surface of the LED wick 11.

[0041] When restarted, the dual-axis motor 4 drives the rotating column 41 to rotate in the opposite direction, at which time the first winding roller 542 winds up the first pulling rope 544, and the second winding roller 543 unwinds the second pulling rope 545. During the winding process, the first pulling rope 544 pulls the sliding block 523 to move to the other side in the guide groove 521. The protective cover 3 rotates 180 degrees in the opposite direction synchronously.

[0042] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
