Abstract
Description
Technical Field
[0001] This utility model relates to the field of lighting fixtures, and in particular to a color-changing lighting fixture controller. Background Technology
[0002] Each LED in an RGB three-channel RGB lighting fixture contains three primary colors: red (R), green (G), and blue (B). By adjusting the brightness and ratio of these three colors using a controller, millions of colors can be mixed using the three-primary-color principle to achieve various dynamic, static, gradient, and abrupt lighting effects. The RGBW four-channel RGB lighting fixture adds a dedicated white (W) chip to the RGB base. Besides creating various colors by mixing red, green, and blue, it can also directly provide white light from the white chip. Furthermore, the controller adjusts the current of the four color chips to achieve richer color reproduction and color temperature adjustment. When multi-colored lighting fixtures need to be spliced together, they usually need to be connected end to end through connectors. However, when different types of lighting fixtures are combined, different specifications of connectors are required for connection. Lighting fixtures that are connected end to end are not flexible enough in actual use and cannot meet complex needs. To solve the above problems, a multi-colored lighting fixture controller is proposed. Utility Model Content
[0003] The purpose of this invention is to solve the problems of poor splicing flexibility and the need for special connectors for cross-type combinations in existing RGB lighting fixtures.
[0004] The present invention adopts the following technical solution: A color-changing lighting controller includes a central cylinder and several bases sleeved on the central cylinder. Limiting discs are provided at both the upper and lower ends of the central cylinder for limiting the positions of the bases. One end of each base is semi-circular with an opening at its center for fitting onto the central cylinder and rotating around it. Several adjusting grooves are provided on the outer edge of the semi-circle. A folding rod is provided on the limiting disc for engaging within the adjusting groove. The other end of each base has a slot containing a central connector for connecting to the color-changing lighting fixture. The central cylinder is divided into an inner cylinder and an outer cylinder, which are connected by threads. The top of the inner cylinder and the bottom of the outer cylinder are respectively provided with a limiting plate. The size of the limiting plate is larger than the size of the central opening of the base, so as to prevent the base from detaching from the central cylinder. Furthermore, a support rod is fixedly installed on the outermost side of the limiting plate at the bottom of the outer cylinder. A folding rod is installed on the support rod via a rotating shaft. The length of the folding rod is equal to the height of several bases. A connecting rod is installed at the end of the folding rod via a rotating shaft. The limiting plate has a latch, and the connecting rod is connected to the limiting plate on the inner cylinder via the latch. Furthermore, the adjustment slots of multiple bases located at the folding rod form a large through slot, and the folding rod is inserted into the through slot to limit the position of several bases; Furthermore, the slot has guide bars on both sides, a flexible positioning block in the middle of the guide bars, a power outlet inside the slot, sliding grooves on both sides of the middle connector, a positioning groove in the middle of the sliding grooves, a power outlet head at the front end of the middle connector, and an adaptation interface at the end of the middle connector. Furthermore, the middle connector is inserted into the slot through the sliding grooves on both sides and the guide bar of the slot. The positioning block matches the shape of the positioning groove, and both the positioning block and the positioning groove are located in the middle of the slot and the middle connector. The power outlet matches the power outlet head for electrical connection. Furthermore, the adapter interface is selected from one or more of the interfaces adapted to RGB three-channel RGB lighting fixtures and RGBW four-channel RGB lighting fixtures; Furthermore, the base is connected to an external controller.
[0005] The beneficial effects of this utility model are: The base can rotate around the central cylinder and be fixed by a folding rod, making the connection direction of the RGB lighting fixtures adjustable. It is no longer limited to the way of connecting end to end. Users can flexibly adjust the angle of each base according to actual installation needs to adapt to complex lighting scenarios, such as arc, circle or polygon layout, to meet diverse lighting needs. The connector adopts a modular design and can be adapted to the interface of RGB three-channel or RGBW four-channel RGB lighting fixtures. It can be compatible with different types of lighting fixtures without replacing the entire controller or using different connectors, which simplifies the installation process and reduces inventory and management costs. The threaded connection design of the inner and outer cylinders of the center cylinder allows for fine-tuning of the length. Combined with the axial limiting of the limiting plate and the circumferential limiting of the folding rod, it ensures that the overall structure of the lamp assembly is firm. The sliding groove and guide bar of the middle connector and the anti-loosening structure of the positioning block and positioning groove simplify the plugging operation and ensure the reliability of the electrical connection. The base and the center connector are both independent modules. If a single lamp fails or the interface type needs to be changed, you only need to unplug the corresponding center connector and replace it, without disassembling the entire controller.

Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0010] Example 1 This utility model provides a color-changing lighting controller, including a central cylinder 3 and several bases 1 sleeved on the central cylinder 3. The number of bases 1 is selected according to actual use, so the number of bases 1 is not limited. The central cylinder 3 is divided into an inner cylinder 5 and an outer cylinder 4, which are fixed by threads. Different lengths of central cylinder 3 and folding rods 8 matching the central cylinder 3 are selected according to different numbers of bases 1. Limiting discs 6 are respectively provided at the top of the inner cylinder 5 and the bottom of the outer cylinder 4 to limit the bases 1. The diameter of the limiting disc 6 is larger than the diameter of the central opening of the base 1, thereby preventing the bases 1 from detaching from the central cylinder 3. There are several bases 1. One end of each base 1 is semi-circular, and an opening is provided at the center of the semi-circle for fitting onto the central cylinder 3 and rotating around the central cylinder 3. Several adjustment grooves 2 are provided on the outer edge of the semi-circular base 1. The adjustment grooves 2 are used to cooperate with the folding rod 8 to fix the position of the base 1. The other end of the base 1 is provided with a slot 11. A middle connector 15 is installed in the slot 11. The middle connector 15 is used to connect with the RGB lighting fixture. A support rod 7 is fixedly installed on the outermost side of the limiting plate 6 at the bottom of the outer cylinder 4. A folding rod 8 is connected to the support rod 7 via a pivot. The length of the folding rod 8 is equal to the sum of the heights of several bases 1, so that the folding rod 8 can cover multiple bases 1. The end of the folding rod 8 is connected to a connecting rod 9 via a pivot. A latch 10 is provided on the limiting plate 6. The connecting rod 9 is connected to the limiting plate 6 at the top of the inner cylinder 5 via the latch 10, thereby fixing the folding rod 8 to one side. When the folding rod 8 is lowered, the adjustment slots 2 of the multiple bases 1 located at the folding rod 8 will combine into a large through slot. The folding rod 8 is inserted into the through slot, thereby limiting the position of several bases 1 at the same time and preventing the bases 1 from rotating. When it is necessary to adjust the position of the bases 1, the folding rod 8 can be lifted to allow the bases 1 to rotate freely. After adjustment, the folding rod 8 can be lowered to fix it. The slot 11 has guide bars 12 on both sides, and a flexible positioning block 13 in the middle of the guide bars 12. The slot 11 has a power outlet 14 inside for power supply and data transmission. The middle connector 15 has sliding grooves 16 on both sides, and a positioning groove 17 in the middle of the sliding grooves 16. The middle connector 15 has a power head 18 at the front end and an adaptation interface 19 at the end. The middle connector 15 is inserted into the slot 11 through the sliding grooves 16 and the guide bars 12 of the slot 11. The positioning block 13 and the positioning groove 17 are shaped to match, so as to achieve precise positioning and fixation of the middle connector 15. The power head 18 contacts the power outlet 14 to achieve electrical connection. When the positioning block 13 and the positioning groove 17 are aligned, the power head 18 aligns with the power outlet 14, and the entire middle connector 15 extends into the slot 11. The middle connector 15 is a modular structure that only adapts to different interfaces 19. Different middle connector 15 modules can be replaced according to the actual type of lamp used, thus making it compatible with RGB and RGBW lamps and even unique different types of RGB lamps. Alternatively, the same type of connector can be used so that the two ends of the same type of lamp can be inserted into the two adjacent bases 1 to achieve a closed loop. In practical use, the user first selects the length of the central tube 3 according to the number of RGB lighting fixtures to be connected, and then fits the required number of bases 1 onto the central tube 3. The bases 1 are fixed by rotating the inner tube 5 and the outer tube 4. The bases 1 can rotate around the central tube 3 to adjust the connection direction. Then, the folding rod 8 is lowered so that it is inserted into the through groove formed by the adjustment groove 2 of the base 1 to fix the position of the base 1. Finally, the middle connector 15 is inserted into the slot 11 of the base 1. The adaptation interface 19 of the middle connector 15 is plugged into the connector of the RGB lighting fixture to achieve mechanical and electrical connection. By adjusting the current of each color chip through the controller, a variety of lighting effects can be achieved.
