Description

Technical Field

[0001] This utility model relates to the field of stage lighting technology, and in particular to a lens disk focusing structure for a stage light. Background Technology

[0002] In the field of stage lighting, the precision, stability, and smoothness of the focusing structure play a crucial role in achieving efficient, sharp, and clear lighting effects, as they directly affect the lighting performance, such as clarity and brightness.

[0003] In existing technology, the focusing structure of a stage light's lens disk uses a lifting focusing module at one end and a lifting guide module at the other end, located between the lens disk and the plate containing the light source. The lifting focusing module includes a linear stepper motor mounted on the plate containing the light source, a focusing lead screw mounted on the linear stepper motor, and a lead screw sleeve fixed to the edge of the lens disk corresponding to the focusing lead screw. When the linear stepper motor drives the focusing lead screw to rotate, the lead screw sleeve moves up and down along the focusing lead screw, thereby causing the lens disk to move up and down relative to the light source, achieving focusing. However, this focusing structure only uses the lifting focusing module at one end to move the lens disk up and down relative to the light source; the lifting guide module at the other end only serves a guiding function. This makes it difficult to ensure balance at both ends, and the smoothness, accuracy, and instantaneous focusing response of the focusing are poor. Utility Model Content

[0019] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of protection of this utility model.

[0020] Please see Figure 1 , Figure 2 and Figure 3 A lens disk focusing structure for a stage light includes a base 10, a lens disk unit 20 disposed above the base 10, and two sets of lifting and traction modules 30 disposed opposite to each other between the base 10 and the lens disk unit 20. The base 10 has several light source elements 11 on its top surface for illuminating the lens disk unit 20 and two positioning ports 12 recessed on its two sides. Each lifting and traction module 30 is correspondingly disposed at a positioning port 12 and includes a traction bracket 31 erected between the base 10 and the lens disk unit 20, a fixing seat 32 connecting the traction bracket 31 to the base 10, a dual-axis motor 33 disposed at the bottom of the traction bracket 31, and two sets of traction components 34 disposed opposite to each other on both sides of the traction bracket 31. The dual-axis motor 33 has two drive shafts extending to both sides of the traction bracket 31.

[0021] Each traction assembly 34 includes a drive wheel 341 rotatably mounted on the top of one side of the traction bracket 31, a drive wheel 342 mounted on the drive shaft on the same side as the drive wheel 341, a traction belt 343 sleeved on the drive wheel 341 and the drive wheel 342, and a traction member 344 connecting the traction belt 343 to the bottom of the lens disk unit 20. The two sets of lifting traction modules 30 are started synchronously, and the two drive shafts of the dual-axis motor 33 rotate synchronously to drive the two sets of traction assemblies 34 to operate, thereby lifting and lowering the lens disk unit 20.

[0022] Furthermore, in this embodiment, the chassis 10 has two guide rods 13 facing each other on both sides of each positioning port 12. The lens disk unit 20 has a through hole 201 at the bottom corresponding to each guide rod 13 and a guide sleeve 202 installed in the through hole 201, so that the guide rod 13 passes through the corresponding guide sleeve 202, thereby playing a guiding role when the lens disk unit 20 is raised and lowered.

[0023] Furthermore, in this embodiment, a position sensor 311 is provided on the side of the traction bracket 31 facing the lens disk unit 20 at a position corresponding to the highest preset position that the lens disk unit 20 can rise to; see reference. Figure 4 The lens disk unit 20 includes a base frame 21 and a lens disk body 22 disposed above the base frame 21. The base frame 21 has the through-hole 201 and the guide sleeve 202 installed thereon. The base frame 21 has connecting sections 211 on both sides of its edge that are directly opposite the traction bracket 31, and the connecting sections 211 are connected to the traction member 344. The connecting section 211 has a trigger member 212 at the top that corresponds to the position sensor 311. When the lens disk unit 20 rises to the highest position, the trigger member 212 is flush with the position sensor 311 and triggers the position sensor 311 to stop the rise of the lens disk unit 20.

[0024] Furthermore, in this embodiment, the bottom frame 21 is provided with a plurality of rotatable support rollers 203 at a top spacing of the edge, and the number of support rollers 203 is not less than 3. The lens disk body 22 is rotatably arranged among the plurality of support rollers 203.

[0025] Furthermore, in this embodiment, the bottom frame 21 is provided on one side with a rotation drive module (not shown) for rotating the lens disk body 22.

[0026] Furthermore, in this embodiment, the lens disk body 22 is formed with a first lens 221 disposed at the center, a plurality of second lenses 222 arranged in an inner ring array centered on the first lens 221, a plurality of third lenses 223 arranged in an outer ring array centered on the first lens 221, and a spacer 224 that separates adjacent lenses from each other; the edge of the bottom frame 21 is disposed on the outer side of the lens disk body 22, and a plastic light edge 213 corresponding to the spacer 224 is formed in the inner edge of the bottom frame 21. When the light source 11 illuminates the lens disk unit 20, as the lens disk body 22 rotates, the spacer 224 and the plastic light edge 213 form a positional deviation, which can form different lighting effects.

[0027] Furthermore, in this embodiment, the traction bracket 31 is formed with two support plates 312 disposed opposite to both sides of the dual-axis motor 33, a plurality of connecting rods 313 and a connecting plate 314 disposed above the dual-axis motor 33 to connect the two support plates 312, the transmission wheel 341 is disposed on the top of the support plate 312 on the same side, and the position sensor 311 is disposed on the connecting plate 314.

[0028] Understandably, the focusing method of the lens disk focusing structure of this utility model for a stage light is as follows: Two sets of lifting and traction modules 30 are started synchronously, and the two drive shafts of the dual-axis motor 33 rotate synchronously to drive the two sets of traction components 34 to operate, pulling the lens disk unit 20 to rise and fall. At the same time as rising and falling, the guide sleeve 202 rises and falls along the corresponding guide rod 13, improving the stability of the lens disk unit 20's rise and fall. In this way, while ensuring balance, the distance between the lens disk unit 20 and the light source 11 can be quickly adjusted to achieve precise focusing.

[0029] In summary, the lens disk focusing structure of this utility model, through the cooperation between the chassis 10, the lens disk unit 20 and the two sets of lifting and traction modules 30, can ensure balance while quickly adjusting the distance between the lens disk unit 20 and the light source 11, thus achieving precise and smooth focusing.
