[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] In the description of this invention, it should be understood that the terms "center," "middle," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicating orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0023] As attached Figure 1 To be continued Figure 3 As shown, a focusing device for improving stage lighting effects includes a support 1 and at least one guide rod 2. Preferably, two guide rods 2 are symmetrically arranged, which is beneficial to the stability of the focusing device's movement and adjustment. The upper and lower ends of the guide rod 2 are respectively fixedly connected to the support 1 through a fixed seat 3. The guide rod 2 is slidably fitted with a guide sleeve seat 20. The guide sleeve seat 20 is fixedly connected to a carrier seat 4 for mounting a focusing lens 40. The carrier seat 4 slides up and down with the guide sleeve seat 20. One of the fixed seats 3 is fixedly provided with a light-shielding block 5 extending along the length direction of the guide rod 2. The light-shielding block 5 is used to block the reflected light from the guide rod 2 from entering the focusing lens 40, preventing more stray light and thus improving the lighting effect quality of the stage lights.

[0024] In this embodiment, the light-shielding block 5 is disposed on the fixing seat 3 at the upper end of the guide rod 2, and the length of the light-shielding block 5 extends from top to bottom; the length direction of the light-shielding block 5 is parallel to the length direction of the guide rod 2; the length of the light-shielding block 5 is greater than 1 / 2 of the length of the guide rod 2, and the width of the light-shielding block 5 is preferably greater than the diameter of the guide rod 2. This design of the light-shielding block 5 can achieve a better light-blocking effect.

[0025] In this embodiment, an anti-reflective pad 6 is provided on the side of the light-shielding block 5 away from the guide rod 2. The pad 6 is a black light-absorbing component to prevent the light-shielding block 5 from reflecting light and further improve the lighting effect.

[0026] In this embodiment, an annular light shield 7 is fixedly installed on the carrier base 4, surrounding the focusing lens 40. In addition to the focusing lens 40, there is also a light-emitting lens located directly above the focusing lens 40 inside the stage light. The annular light shield 7 can effectively block some stray light from the edges from entering the light-emitting lens, further optimizing the stage light effect. The optimized light effect is mainly reflected in the uniformity of the light spot, the light mixing effect, and the center illuminance.

[0027] As attached Figure 2As shown, the carrier base 4 includes a fixing part 41, a connecting part 42, and an annular support part 43. The annular support part 43 has a light-transmitting hole in the middle to facilitate light transmission. The fixing part 41 is fixedly connected to the guide sleeve base 20. One end of the connecting part 42 is fixedly connected to the fixing part 41, and the other end of the connecting part 42 is fixedly connected to the support part 43. The diameter of the annular light-shielding plate 7 is larger than the diameter of the support part 43 to achieve a light-shielding effect. The focusing lens 40 is mounted on the support part 43.

[0028] In this embodiment, two connecting parts 42 are provided at intervals to enhance the stability of the connection between the fixing part 41 and the bearing part 43; an avoidance hole 44 is formed between the two connecting parts 42, and the light-shielding block 5 passes through the avoidance hole 44, making the structure of the focusing device more compact.

[0029] In this embodiment, one side of the annular light shield 7 is provided with an extension portion 71 that extends outward to partially block the avoidance hole 44, thereby increasing the light shielding area of ​​the annular light shield 7 and minimizing the amount of residual light passing through the avoidance hole 44.

[0030] As attached Figure 3 As shown, the fixing seat 3 at the upper end of the guide rod 2 is plate-shaped, and the fixing seat 3 has a through hole. The end of the guide rod 2 is sleeved with the through hole through a rubber ring 8. The outer periphery of the rubber ring 8 has an annular groove 81. The rubber ring 8 is embedded in the inner ring edge of the through hole through the annular groove 81. The middle part of the rubber ring 8 also has a sleeve hole 82 for the end of the guide rod 2 to be sleeved. The rubber ring 8 can play a shock absorption role, provide smooth focusing movement, and extend service life.
