Four through openings are opened on the outside of the tube frame 22, and arc grooves are opened on the front side and the rear side of the inner wall of the opening. Sliders 24 are slidably installed on both sides of the inner wall of the arc groove of the tube frame 22, and arc-shaped color sheets 23 are fixed between the four slides 24. Through the arrangement of the above structure, the tube frame 22 drives the arc-shaped color sheet 23 to rotate to the bottom of the lamp body 7, so that the light color of the lamp body 7 can be adjusted.

[0030] The adjusting device 3 includes a screw 31, a through-slot plate 32, two slide posts 33, two inner arc plates 35, two connecting blocks 37, two T-shaped posts 38, two elastic telescopic plates 39, and two U-shaped plates 310. The screw 31 is rotatably mounted on the front side of the lamp housing 1. The through-slot plate 32 is threadedly connected to the outside of the screw 31, and the through-slot plate 32 is slidably mounted on the front side of the lamp housing 1. Through slots are provided on both sides of the through-slot plate 32. The two slide posts 33 are respectively slidably mounted in the two through slots of the through-slot plate 32.

[0031] The adjusting device 3 also includes two outer arc plates 36 and two contact rollers 311. The two outer arc plates 36 are respectively fixed on the rear sides of the two connecting blocks 37, and the two outer arc plates 36 are located on the outside of the tube frame 22. The two contact rollers 311 are respectively rotatably installed at the bottom of the telescopic ends of the two elastic telescopic plates 39, and the contact rollers 311 are in contact with the inner wall of the tube frame 22. Through the arrangement of the above structure, the shielding area of ​​the arc color film 23 by the outer arc plates 36 becomes larger, thereby reducing the area of ​​the arc color film 23 exposed to the external environment, thereby reducing the influence of external factors such as dust, pollution, and physical damage on the arc color film 23, and extending the service life of the arc color film 23. At the same time, the telescopic end of the elastic telescopic plate 39 will drive the contact roller 311 to contact the inner wall of the tube frame 22, thereby avoiding the problem that the telescopic end of the elastic telescopic plate 39 directly rubs against the inner wall of the arc color film 23 when moving, causing the inner wall of the arc color film 23 to be scratched, affecting the optical performance of the arc color film 23.

The L-shaped pressing piece 45 is used to control the cleaning liquid in the cleaning liquid tank 43 to be transmitted to the spray pipe 44 for spraying. Through the setting of the above structure, the cleaning brush roller 41 carries the cleaning liquid to clean the arc color film 23, thereby effectively removing dust and other contaminants on the surface of the arc color film 23, thereby ensuring that the arc color film 23 maintains good optical properties and avoiding the problem of contaminants affecting lighting effects or color accuracy.

[0034] When in use, when the light color of the lamp main body 7 needs to be adjusted, the motor 21 is started, and the disk at the output end of the motor 21 drives the drum frame 22 to rotate through the belt, and the drum frame 22 drives the arc color piece 23 to rotate to the bottom of the lamp main body 7, so as to adjust the light color of the lamp main body 7.

At the same time, the telescopic end of the elastic telescopic plate 39 will drive the contact roller 311 to contact with the inner wall of the tube frame 22, thereby avoiding the problem that the telescopic end of the elastic telescopic plate 39 directly rubs against the inner wall of the arc color film 23 when moving, causing the inner wall of the arc color film 23 to be scratched, affecting the optical performance of the arc color film 23.

[0035] At the same time, after the surface of the arc-shaped color sheet 23 is contaminated by dust or other pollutants, the disc at the output end of the motor 21 drives the drum frame 22 to rotate continuously through the belt. Under the friction between the friction wheel 42 and the drum frame 22, the drum frame 22 drives the friction wheel 42 to rotate, and the friction wheel 42 drives the cleaning brush roller 41 to rotate.

Excess cleaning liquid or sewage will flow into the cavity of the outer arc plate 36 for discharge.

[0036] See also Figure 1-Figure 10 On the basis of the above embodiment, in another embodiment of the present invention, a pushing device 5 is provided inside the cartridge frame 22 .

[0037] The pushing device 5 includes a slide plate 52, an L-shaped column 53, a semicircular block 54, four elastic telescopic rods 51, and a plurality of arc-top telescopic rods 55. The fixed ends of the four elastic telescopic rods 51 are respectively fixed to the front side and the rear side of the inner wall of the lamp housing 1. The slide plate 52 is fixed to the top of the telescopic end of the four elastic telescopic rods 51. The L-shaped column 53 is fixed to one side of the top of the slide plate 52. The semicircular block 54 is fixed to the eccentric front side of the disk at the output end of the motor 21 (combined with the Figure 5 and Fig.10 ), the top of the rear side of the L-shaped column 53 is set in a cylindrical shape, and the cylindrical lower semicircular surface of the L-shaped column 53 is located on the movement trajectory of the semicircular block 54. The fixed ends of several arc-top telescopic rods 55 are evenly and equidistantly fixed on the top of the slide plate 52, and the tops of the telescopic ends of several arc-top telescopic rods 55 are in contact with the side of the arc-shaped color sheet 23 close to the center of the cylinder frame 22. Through the setting of the above structure, the arc-top telescopic rod 55 will push the bottom surface of the arc-shaped color sheet 23 to drive the arc-shaped color sheet 23 to bend slightly upward. The micro-bending can help remove dust and pollutants on the surface of the arc-shaped color sheet 23. If there is dust adhering to the surface of the color sheet, the micro-bending can make it fall off through physical disturbance, thereby facilitating the maintenance of the cleanliness of the arc-shaped color sheet 23.

[0038] The pushing device 5 also includes a plurality of fixed rods 56 and a plurality of zigzag scrapers 57. The plurality of fixed rods 56 are evenly and equidistantly fixed at the bottom of the slide plate 52. Two of the plurality of fixed rods 56 form a group. The plurality of zigzag scrapers 57 are respectively fixed at the bottom of two adjacent fixed rods 56, and the zigzag scrapers 57 are sleeved on the outside of the heat dissipating fins 8. Through the arrangement of the above-mentioned structure, the up and down movement of the zigzag scrapers 57 can effectively remove dust, dirt or scale on the heat dissipating fins 8 and keep their surface clean, which helps to maintain the heat dissipation efficiency of the heat dissipating fins 8 and prevent the heat dissipation performance from being reduced due to dirt accumulation.

[0039] When in use, when the disc at the output end of the motor 21 rotates, it will drive the semicircular block 54 to rotate, and the semicircular block 54 pushes the cylindrical lower semicircular surface of the L-shaped column 53 to drive the L-shaped column 53 to move upward, and the L-shaped column 53 pulls the slide plate 52 to move upward, and the slide plate 52 drives the telescopic end of the elastic telescopic rod 51 to stretch upward. When the semicircular block 54 no longer pushes the cylindrical lower semicircular surface of the L-shaped column 53, under the elastic force of the elastic telescopic rod 51, the elastic telescopic rod 51 drives the slide plate 52 to reset and move downward. Every time the slide plate 52 moves upward, the slide plate 52 drives the arc top telescopic rod 55 to move upward. When the area above the arc top telescopic rod 55 is the arc-shaped color sheet 23, the arc top telescopic rod 55 will push the bottom surface of the arc color sheet 23 to drive the arc color sheet 23 to bend slightly upward, and slightly deform. Bending can help remove dust and contaminants on the surface of the arc-shaped color sheet 23. If dust adheres to the surface of the color sheet, the micro-bending can cause it to fall off through physical disturbance, thereby facilitating the maintenance of the cleanliness of the arc-shaped color sheet 23. When the area above the arc-top telescopic rod 55 is the tube rack 22, the upward movement of the arc-top telescopic rod 55 will cause the telescopic end of the arc-top telescopic rod 55 to contract; at the same time, each time the slide plate 52 moves up and down, the slide plate 52 drives the fixed rod 56 to move up and down, and the fixed rod 56 drives the meandering scraper 57 to move up and down on the outside of the heat dissipating fin 8. The up and down movement of the meandering scraper 57 can effectively remove dust, dirt or scale on the heat dissipating fin 8 and keep its surface clean, which helps to maintain the heat dissipation efficiency of the heat dissipating fin 8 and prevent the heat dissipation performance from being reduced due to dirt accumulation.
