[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example

[0029] See Figures 1 to 4 As shown, a full-color gamut lighting fixture structure includes a mounting frame 1, a lamp holder 2 snapped onto the mounting frame, a light source board 3 fixed inside the lamp holder, and a light-transmitting lampshade 4 on the lamp holder. The light source board is equipped with a power circuit 5, a control circuit 6 connected to the power circuit, and several LED groups 7 connected to the control circuit. Each LED group includes a red LED group 71, a green LED group 72, a blue LED group 73, and a white LED group 74, all sharing a common positive electrode and with their negative electrodes connected to the control circuit. In this embodiment, the lamp holder is either a plastic or aluminum base. The mounting frame is a conventional structure in the prior art, matching the shape and size of the mounting cavity. The light-transmitting lampshade is also a conventional structure in the prior art, simply applied. During use, different colors of light from different LED groups are combined to achieve different color gamut adjustments, meeting various usage requirements.

[0030] Furthermore, the lamp holder has an integrally formed support protrusion 8 at the center of its bottom surface, and an integrally formed mounting rib 9 between the edge of the support protrusion and the inner wall of the lamp holder's edge. The mounting rib has mounting holes 10. A screw post 11 is fixed to the inner wall of the lamp holder's edge. During assembly, the light source plate is attached to the bottom surface of the support protrusion and the mounting rib and fixed with screws. The edge of the light-transmitting lampshade is attached to the screw post and fixed with screws. Through this structure, the mounting rib area is hollowed out after the light source plate is installed, which facilitates heat dissipation, improves heat dissipation effectiveness, and also facilitates the convenient and effective installation of the light source plate and the light-transmitting lampshade.

[0031] In this embodiment, the red LED group comprises multiple red LEDs connected in series; the green LED group comprises multiple green LEDs connected in series; the blue LED group comprises multiple blue LEDs connected in series; and the white LED group comprises multiple white LEDs connected in series. In practical applications, the LED groups are connected in parallel and then connected to the control circuit board, thereby meeting the lighting needs of different LEDs. The number of LED groups can be set as needed, with a minimum of four groups, allowing each group to illuminate different colors of LEDs, thus combining light to meet full color gamut illumination requirements.

[0032] In this embodiment, the top surface of the lamp holder has a mounting cavity 12, and a positioning protrusion 13 is fixed to the upper part of the inner wall of the mounting cavity; the lower side of the mounting bracket has an integrally formed inclined snap-fit ​​protrusion 14, and the bottom surface of the mounting bracket is fixed with a Z-shaped support bracket 15 by screws. The upper horizontal edge of the Z-shaped support bracket has an integrally formed downwardly bent mounting lug 16. The power box is placed on the mounting bracket and fixed to the mounting lug by screws; the mounting bracket is located in the mounting cavity, and the positioning protrusion engages with the inclined snap-fit ​​protrusion for positioning. This structure not only improves the convenience and reliability of the connection with the lamp holder, but also facilitates the installation and positioning of the power box through the Z-shaped support bracket and mounting lug.

[0033] In this embodiment, the bottom surface of the lamp holder is provided with a clearance groove 17 that communicates with the mounting cavity; during assembly, the lower transverse part of the Z-shaped support frame fits into the clearance groove for limitation. This can prevent the Z-shaped support frame from affecting the connection between the mounting bracket and the lamp holder, ensuring the effectiveness and reliability of the connection.

[0034] This utility model has the following positive effects: Its structure is rationally designed, incorporating several LED light groups, including red, green, blue, and white LED groups with a common positive electrode and a negative electrode connected to the control circuit. This allows for the combination of different colors from the LED groups to achieve full-gamut color adjustment, meeting various usage needs. Furthermore, a support protrusion is integrally formed in the center of the bottom surface of the lamp holder, and mounting ribs are integrally formed between the edge of the support protrusion and the inner wall of the lamp holder. This facilitates the installation and positioning of the light source board, improving installation convenience and heat dissipation. The system is stable, reliable, and highly adaptable.

[0035] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0036] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
