Description

Technical Field

[0001] This utility model relates to the field of stage lighting technology, specifically an adjustable stage lighting stand. Background Technology

[0002] Stage lighting rigs are metal structural devices used to fix and support stage lighting equipment. They are usually made of high-strength materials such as aluminum alloy and steel, and can be adapted to the installation needs of different lighting equipment (PAR lights, beam lights, effect lights, follow spots, etc.).

[0003] While existing stage lighting rigs can achieve basic stability after installing PAR lights, effect lights, and other lighting fixtures, excessive rotation angles (such as excessive pitch or horizontal rotation) can cause light to leak from the sides or back of the fixtures, creating glare. This glare can disrupt the harmony of the stage background lighting and even affect the audience's vision. Therefore, we propose an adjustable stage lighting rig. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable stage lighting stand to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an adjustable stage light stand, comprising a support frame, a top block fixedly connected to the top of the support frame, a fixing ring installed in the middle of the support frame, and a top rod and a bottom rod fixedly connected to both sides of the top block and the fixing ring, respectively;

[0006] Each of the top rods has a top groove extending through its middle section. Each top block has a receiving groove in its middle section. A rotating rod extending through the inner wall of each receiving groove is rotatably connected to the inner wall of both top grooves. A take-up roller is fixedly connected to the wall of each rotating rod within the top groove. An anti-glare curtain is wound inside the groove of each take-up roller. Positive soft magnetic blocks are provided near the lower ends of the two outer walls of the anti-glare curtain. Each of the bottom rods has a bottom groove extending through its interior. A bottom negative magnetic block and a top negative magnetic block are fixedly connected to the inner side walls of the bottom groove and the top groove, respectively. A motor is fixedly connected to the top of the top block. A first bevel gear is fixedly connected to the output end of the motor. The first bevel gear meshes with a second bevel gear fixedly connected to the rotating rod.

[0007] Preferably, the top and bottom ends of the top rod and the bottom rod are respectively staggered and equipped with several sets of PAR lamp assemblies and effect lamp assemblies.

[0008] Preferably, both the bottom negative magnetic block and the top negative magnetic block are magnetically connected to the positive soft magnetic block.

[0009] Preferably, the diameter of the top groove is smaller than the diameter of the bottom groove, and the top groove and the bottom groove are vertically aligned.

[0010] Preferably, the anti-glare screen is made of thin nylon or cotton-linen blend material, and the anti-glare screen is semi-transparent.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the anti-glare curtain is raised and lowered by driving the winding roller with a motor, which can quickly block glare when the light angle is too large and can be flexibly retracted when not needed. The lighting and anti-glare modes can be flexibly switched according to the scene, improving the flexibility of stage lighting adjustment and ease of use. Attached Figure Description

[0018] 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.

[0019] Please see Figure 1-5 The present invention provides the following technical solution:

[0020] Example 1: An adjustable stage lighting rig includes a support frame 1, a top block 2 fixedly connected to the top of the support frame 1, a fixing ring 3 installed in the middle of the support frame 1, a top rod 21 and a bottom rod 31 fixedly connected to the top block 2 and the fixing ring 3 respectively, and several sets of PAR light assemblies 4 and effect light assemblies 5 are installed at the top and bottom ends of the top rod 21 and the bottom rod 31 in a staggered manner.

[0021] In use, the support frame 1 is fixed in the preset position on the stage, and the top block 2 and the fixing ring 3 are used to support the top rod 21 and the bottom rod 31 respectively. According to the stage lighting design requirements, PAR light components 4 and effect light components are installed at the top and bottom ends of the top rod 21 and the bottom rod 31 (the staggered installation can avoid the lights from blocking each other). By adjusting the angle of the lights themselves, the PAR lights provide basic lighting and the effect lights present specific light and shadow effects, thus completing the overall lighting layout and adapting to conventional stage lighting scenarios.

[0022] Example 2: The technical solution of this example, which differs from Example 1, includes: a top groove 201 penetrating the middle of each top rod 21; a receiving groove 202 in the middle of the top block 2; a rotating rod 22 rotatably connected to the inner wall of the receiving groove 202, penetrating to the inner wall of the two top grooves 201; a take-up roller 23 fixedly connected to the rod wall of the rotating rod 22 within the top groove 201; an anti-glare curtain 24 wound inside the roller groove of the take-up roller 23; positive soft magnetic blocks 25 are provided on the two outer walls of the anti-glare curtain 24 near the lower end; a bottom groove 301 penetrating the inside of each bottom rod 31; and the two inner walls of the bottom groove 301 and the top groove 201 respectively... The bottom negative magnetic block 32 and the top negative magnetic block 26 are fixedly connected. The top of the top block 2 is fixedly connected to the motor 211. The output end of the motor 211 is fixedly connected to the first bevel gear 212. The first bevel gear 212 meshes with the second bevel gear 220 fixedly connected to the rotating rod 22. The bottom negative magnetic block 32 and the top negative magnetic block 26 are magnetically connected to the positive soft magnetic block 25. The diameter of the top groove 201 is smaller than the diameter of the bottom groove 301, and the top groove 201 and the bottom groove 301 are vertically aligned. The anti-glare curtain 24 is made of thin nylon or cotton-linen blend material and is semi-transparent.

[0023] In use, if the lamps rotate too much and cause glare, the motor 211 is started. The first bevel gear 212 meshes with the second bevel gear 220, driving the rotating rod 22 to rotate, causing the take-up roller 23 to release the anti-glare curtain 24. The anti-glare curtain 24 falls along the top groove 201 to the bottom groove 301 (the diameter of the bottom groove 301 is larger than the diameter of the top groove 201 to prevent the anti-glare curtain 24 from getting stuck). The positive magnetic block 25 and the bottom negative magnetic block 32 are attracted and fixed in place. The semi-transparent material effectively blocks glare without affecting the stage atmosphere. When anti-glare is not needed, the motor rotates in the opposite direction to retract the curtain, and the positive magnetic block 25 and the top negative magnetic block 26 are attracted and fixed in place to prevent shaking.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
