Technical Field

[0002] LED module refers to a modular component for light-emitting diodes (LEDs), which consists of multiple LED chips that are integrated on a common substrate. The module is designed to provide uniform lighting effects and can achieve multiple lighting functions through simple circuit connections. LED modules are generally characterized by high brightness, low energy consumption and long life, making them ideal for a variety of lighting applications.

[0003] According to the patent document: CN105042384A, a LED module lamp is disclosed. It includes at least one module unit, a power supply mounting plate and a power supply module. Each module unit includes a module radiator, a light source and a lens. The module radiator is composed of a support seat, heat dissipation fins connected to the outer circumference of the support seat and arranged radially, and a square frame connected to the outer periphery of the heat dissipation fins. The light source and the lens are installed on the bottom surface of the support seat. Each heat dissipation fin has an arc so that the airflow through the hollow gaps between the heat dissipation fins can form a cyclone state. The middle of the four sides of the frame of each module unit is provided with a connection position. After adopting the above structure, not only the efficient convection effect is achieved, the maximum heat dissipation surface area is formed, and the heat dissipation capacity is greatly enhanced, the structural design is reasonable, the overall weight is light, and the module units are easy to splice, free splicing and convenient interchange are achieved, the manufacturing and installation are convenient, and the uniformity of light illumination is greatly improved.

[0004] In modern lighting technology, traditional LED modules are usually fixed on light strips by welding technology. This fixing method is applicable in most cases, but in some specific application scenarios, it is particularly important to adjust the density of LED modules. For example, in the field of stage lighting design, designers need to create diverse lighting effects according to different scene requirements. In order to achieve the desired visual effect, they may need to increase or decrease the density of LED modules to achieve richer and more delicate light and shadow changes. In addition, in the application of outdoor billboards or large display screens, in order to adapt to the needs of the audience to watch content from different distances and angles, it is very important to flexibly adjust the layout of LED modules. In this way, it can ensure that no matter where the audience is, they can get the best visual experience.

A sliding rod 34 is slidably connected to the inner wall of the two positioning block rear grooves 32. The bottoms of the two sliding rods 34 are fixedly connected to the tops of the two groups of springs 37. The tops of the two sliding rods 34 extend to the top of the positioning block 31 and are fixedly connected to an L-shaped connecting rod 35. The inner bottoms of the two L-shaped connecting rods 35 extend to the inner wall of the positioning block 31 through the positioning block top groove 33 and are fixedly connected to a U-shaped positioning plate 36.

[0035] In some cases, for example, when designers need to create diverse lighting effects according to different scene requirements and change the density of LED modules, the staff rotates the handle 217, and the rotation of the handle 217 drives the transmission plate 218 to rotate, thereby driving the second transmission plate 2110 to rotate through the crawler 219, and the rotation of the second transmission plate 2110 drives the bidirectional screw rod 2111 to rotate, thereby driving the transmission blocks 2112 at the bottom of the two control rods 211 to move to the opposite side, and the two transmission blocks 2112 move to the opposite side, thereby driving the control rod 211 and the limit plate 214 to be horizontally connected at the top of the bottom connecting frame 210. The rod 21 and the inner wall of the connecting plate 22 move in opposite directions, so that the control rod rack 213 on the inner wall of the control slot 212 opened at the top of the control rod 211 meshes with the bottom gear 26, thereby rotating the top gear 26, and the gears 26 on the inner walls of the two horizontal connecting rods 21 rotate and mesh with the two sets of expansion rods 27 to move in opposite directions, thereby driving the two sets of expansion plates 29 to pull the L-shaped side connecting plates 42 to move in opposite directions, and the two L-shaped side connecting plates 42 move in opposite directions, thereby separating from the I-shaped connecting plate 41 in the middle, and dispersing the top LED lights 44, so as to achieve the density adjustment of the LED module;

[0036] At the same time, when the two control rods 211 move outward, the limiting plate 214 is pushed outward to the inner wall of the two positioning blocks 31. At this time, the outer sides of the two limiting plates 214 push the U-shaped positioning plate 36 to move toward the top on the inner wall of the positioning block 31. After completely moving to the outer side of the U-shaped positioning plate 36, the spring 37 resets the sliding rod 34, the L-shaped connecting rod 35 and the U-shaped positioning plate 36, and clamps them on the side of the limiting plate 214 close to the control rod 211, thereby fixing the overall adjustment;

[0037] Through this mechanical linkage mechanism, designers can easily adjust the brightness and lighting range of the LED light strip according to actual needs to adapt to different environments and scenes. In addition, the design also allows users to achieve different visual effects and lighting needs by replacing LED lights of different sizes or adjusting the layout of LED modules without changing the overall structure. This flexibility and adjustability make the present invention have broad application prospects in commercial lighting, stage effects, decorative lighting and other fields.

[0038] like Figure 8 As shown, the LED lamp fixing component 43 includes a fixing component connecting plate 431, a C-shaped connecting frame 432 is fixedly connected to the right side of the fixing component connecting plate 431, a screw connecting block 433 is fixedly connected to the top of the fixing component connecting plate 431 and the middle part of the right side of the top of the C-shaped connecting frame 432, a T-shaped connecting plate 439 is fixedly connected to the right side of the C-shaped connecting frame 432, a screw 434 is rotatably connected to the inner wall of the left screw connecting block 433, the right end of the screw 434 is movably connected to the left side of the right screw connecting block 433, and the screw 434 is threadedly connected to a push-pull plate transmission block 435 on the outer wall of one side of the inner side of the two screw connecting blocks 433. The bottom of the push-pull plate transmission block 435 is fixedly connected with a push-pull plate 436, the outer wall of the push-pull plate 436 is slidably connected to the inner wall of the C-shaped connection frame 432, the bottom and bottom of the front and rear sides of the push-pull plate 436 are rotatably connected with rotating rods 437 facing oppositely, the two groups of rotating rods 437 are rotatably connected with V-shaped rotating rods 438 on the side away from the push-pull plate 436, the inner middle parts of the two groups of V-shaped rotating rods 438 are rotatably connected to the top and bottom of the front and rear sides of the right side of the T-shaped connection plate 439, the right sides of the two groups of V-shaped rotating rods 438 are fixedly connected with clamping plates 4310, and the inner sides of the two clamping plates 4310 fit the outer wall of the LED lamp 44;

[0039] When the LED lamp 44 is worn out for a long time, it may be damaged and need to be replaced. At this time, the staff only needs to rotate the screw rod 434 on one side of the damaged LED lamp 44. The screw rod 434 rotates the transmission push-pull plate transmission block 435 to move on the inner wall of the C-shaped connection frame 432 to the side away from the T-shaped connection plate 439. At this time, the push-pull plate 436 moves to drive the rotation rod 437 to rotate, and then pulls the V-shaped rotation rod 438 to rotate with the middle T-shaped connection plate 439 as the axis, so that the two clamping plates 4310 expand outward to release the LED lamp 44. The limit of the lamp 44 allows the staff to easily take out the damaged LED lamp 44. After replacing the new LED lamp 44, the reverse operation is performed, that is, the screw rod 434 is rotated to make the push-pull plate transmission block 435 drive the push-pull plate 436 to move toward the T-shaped connecting plate 439, and the rotating rod 437 rotates accordingly. The V-shaped rotating rod 438 rotates inward with the T-shaped connecting plate 439 as the axis, and the clamping plate 4310 clamps the new LED lamp 44 to ensure that it is fixed in the appropriate position. The entire replacement process is simple and quick, which greatly improves the maintenance efficiency and ensures the stable operation of the LED light strip.

[0040] In addition, the present invention also relates to an LED light strip, including the above LED module.

[0041] Working principle of the present invention: In some cases, for example, when designers need to create diverse lighting effects according to different scene requirements and change the density of LED modules, the staff rotates the handle 217, and the rotation of the handle 217 drives the transmission disk 218 to rotate, thereby driving the second transmission disk 2110 to rotate through the crawler 219, and the rotation of the second transmission disk 2110 drives the bidirectional screw rod 2111 to rotate, thereby driving the transmission blocks 2112 at the bottom of the two control rods 211 to move to the opposite side, and the two transmission blocks 2112 move to the opposite side, thereby driving the control rod 211 and the limit plate 214 at the top horizontal connecting rod 21 of the bottom connecting frame 210 and the inner wall of the connecting disk 22 to move in opposite directions, so that the control rod rack 213 on the inner wall of the control groove 212 opened on the top of the control rod 211 engages with the bottom gear 26, thereby causing the top gear 26 to rotate, and the two horizontal connecting rods 211 and the limit plate 214 move to opposite directions. The gear 26 on the inner wall of the connecting rod 21 rotates and then meshes with the two sets of expansion rods 27 to move in opposite directions, thereby driving the two sets of expansion plates 29 to pull the L-shaped side connecting plates 42 to move in opposite directions. The two L-shaped side connecting plates 42 move in opposite directions, thereby being separated from the I-shaped connecting plate 41 in the middle, and the top LED lights 44 are dispersed to achieve the density adjustment of the LED module. At the same time, when the two control rods 211 move outward, they simultaneously push the limit plate 214 to move outward to the inner walls of the two positioning blocks 31. At this time, the outer sides of the two limit plates 214 push the U-shaped positioning plate 36 to move toward the top on the inner wall of the positioning block 31. After completely moving to the outer side of the U-shaped positioning plate 36, the spring 37 resets the sliding rod 34, the L-shaped connecting rod 35 and the U-shaped positioning plate 36, and is stuck on the side of the limit plate 214 close to the control rod 211, thereby fixing the overall adjustment.

[0042] When the LED lamp 44 is worn out for a long time, it may be damaged and need to be replaced. At this time, the staff only needs to rotate the screw rod 434 on one side of the damaged LED lamp 44. The screw rod 434 rotates the transmission push-pull plate transmission block 435 to move on the inner wall of the C-shaped connection frame 432 to the side away from the T-shaped connection plate 439. At this time, the push-pull plate 436 moves to drive the rotation rod 437 to rotate, and then pulls the V-shaped rotation rod 438 to rotate with the middle T-shaped connection plate 439 as the axis, so that the two clamping plates 4310 expand outward to release the LED lamp 44. The limit of the lamp 44 allows the staff to easily take out the damaged LED lamp 44. After replacing the new LED lamp 44, the reverse operation is performed, that is, the screw rod 434 is rotated to make the push-pull plate transmission block 435 drive the push-pull plate 436 to move toward the T-shaped connecting plate 439, and the rotating rod 437 rotates accordingly. The V-shaped rotating rod 438 rotates inward with the T-shaped connecting plate 439 as the axis, and the clamping plate 4310 clamps the new LED lamp 44 to ensure that it is fixed in the appropriate position. The entire replacement process is simple and quick, which greatly improves the maintenance efficiency and ensures the stable operation of the LED light strip.

[0043] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected.
