Description

Technical Field

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

[0002] Stage lighting effectively enhances the stage performance effect, and stage lights are commonly used stage lighting equipment. Stage lights can focus the light source on a single focal point, thereby making the light source more concentrated or dispersed, forming single or multiple beams, thus creating a better stage lighting effect. During a stage performance, stage lights are arranged around the stage, with beams shining onto the stage in multiple directions to create stage lighting effects.

[0003] Currently, stage lights typically include a base, a lamp holder that can be rotatably mounted on the base, and a lamp head that can be swung on the lamp holder. The lamp head has a light-emitting lens mounted on its top, a lighting lamp inside, and several lighting effect modules arranged sequentially between the lighting lamp and the light-emitting lens to create different lighting effects. The light beam formed by the lighting lamp passes through the lighting effect modules and the light-emitting lens, and various lighting effects are created by changing different lighting effect modules.

[0004] Among them, the focusing module and the zoom module are commonly used lighting effect modules in stage lights. By adjusting the distance between the focusing lens of the focusing module and the zoom lens of the zoom module relative to the light-emitting lens, the lighting effect can be changed. However, the focusing module and the zoom module are located inside the lamp, and it would take a lot of manpower and resources to adjust them manually. Utility Model Content

[0021] The lamp head 10 includes a lamp housing 11 and a lamp head bracket 12 disposed inside the lamp housing 11. The lamp head bracket 12 is provided with a lens fixing frame 121 at the top and two side frames 122 connected to the lens fixing frame 121 on opposite sides.

A zoom module 30 and a focus module 40 that can be raised and lowered relative to the light-emitting lens 101 are provided between the two side frames 122, one above the other.

[0022] See also Figure 2 , Figure 3 and Figure 4Each lifting drive unit 20 is mounted on a corresponding side frame 122, and includes a slide rail 21, a zoom traction assembly 22, and a focus traction assembly 23. The slide rail 21, zoom traction assembly 22, and focus traction assembly 23 are all mounted on the inner wall of the side frame 122. The zoom traction assembly 22 and focus traction assembly 23 are arranged opposite each other on both sides of the slide rail 21, and the zoom traction assemblies 22 and focus traction assemblies 23 of the two sets of lifting drive units 20 are mirror-symmetrical. The zoom traction assembly 22 is provided with a connection to the zoom module 30. The first traction block 221 is able to slide along the slide rail 21. The focusing traction assembly 23 is provided with a second traction block 231 that is connected to the focusing module 40 and can slide along the slide rail 21. The two sets of lifting drive units 20 can drive the first traction block 221 to rise and fall with the zoom traction assembly 22. The zoom module 30 rises and falls relative to the light-emitting lens 101 along with the rise and fall of the first traction block 221. The second traction block 231 is driven to rise and fall with the focusing traction assembly 23. The focusing module 40 rises and falls relative to the light-emitting lens 101 along with the rise and fall of the second traction block 231.

[0023] Furthermore, in this embodiment, the length of the slide rail 21 is equal to the length of the inner wall of the side frame 122. The zoom traction component 22 and the focus traction component 23 are of different lengths, one longer than the other. The zoom traction component 22 can drive the first traction block 221 to slide back and forth from the top to the bottom of the slide rail 21, and the focus traction component 23 can drive the second traction block 231 to slide back and forth from the middle to the bottom of the slide rail 21.

[0024] Furthermore, in this embodiment, both the zoom traction assembly 22 and the focus traction assembly 23 include a driven wheel 201 and a transmission wheel 202, which are rotatably mounted on the inner wall of the side frame 122, one above the other, a traction belt 203 sleeved on the driven wheel 201 and the transmission wheel 202, and a drive motor 204 mounted on the outer wall of the side frame 122. The drive motor 204 drives the transmission wheel 202 to rotate, and the traction belt 203 operates as the transmission wheel 202 rotates.

[0025] Furthermore, in this embodiment, the zoom module 30 includes a first lifting seat 31 and a zoom lens 32 disposed at the center of the first lifting seat 31. The two sides of the first lifting seat 31 are connected to the first traction blocks 221 of the two sets of lifting drive units 20, so that when the first traction blocks 221 move up and down with the operation of the traction belt 203, they drive the first lifting seat 31 and the zoom lens 32 to move up and down.

[0026] Furthermore, in this embodiment, the focusing module 40 includes a second lifting seat 41 and a focusing lens 42 disposed at the center of the second lifting seat 41. The two sides of the second lifting seat 41 are connected to the second traction blocks 231 of the two sets of lifting drive units 20, so that when the second traction blocks 231 move up and down with the operation of the traction belt 203, they drive the second lifting seat 41 and the focusing lens 42 to move up and down.

[0027] Furthermore, in this embodiment, the second lifting seat 41 is provided with a prism switching component 43 on the front and rear ends of its top surface, which can rotate relative to the focusing lens 42 to change the lighting effect.

[0030] Understandably, the method of using the dual-lens lifting structure of the stage light of this utility model is as follows: When it is necessary to adjust the setting position of the zoom module 30 and the focus module 40 in the lamp head 10, the zoom traction component 22 or the focus traction component 23 in the two sets of lifting drive units 20 are controlled to operate; in the zoom traction component 22 or the focus traction component 23, the drive motor 204 drives the transmission wheel 202 to rotate, and the traction belt 203 operates with the rotation of the transmission wheel 202. The first traction block 221 and the second traction block 231 rise and fall with the operation of the traction belt 203, so that the zoom module 30 rises and falls along the slide rail 21 relative to the light-emitting lens 101 along with the rise and fall of the first traction block 221, and the focus module 40 rises and falls along the slide rail 21 relative to the light-emitting lens 101 along with the rise and fall of the second traction block 231, thereby conveniently adjusting the setting position of the zoom module 30 and the focus module 40 in the lamp head 10.
