[0002] Film and television lighting is a core device used in film and television production, stage performances, and other professional fields to create lighting effects. Chinese Patent Announcement No. CN208156387U discloses a multifunctional intelligent film and television lighting device, comprising: a mounting platform; a rotating bracket rotatably mounted on the mounting platform, wherein a first bracket and a second bracket are respectively provided at both ends of the rotating bracket; a lampshade body hinged between one end of the first bracket and the second bracket, wherein the lampshade body has a receiving cavity; a light source module disposed in one end of the receiving cavity, wherein the light source module includes a first fixing plate and a light source; a light-emitting lens disposed in the other end of the receiving cavity; and a pattern and color module disposed in the receiving cavity, and the pattern and color module is positioned close to the first fixing plate, wherein the pattern and color module includes a second fixing plate, a first color disc, a second color disc, a third color disc, and a pattern disc. Through the above method, the intelligent film and television lighting device disclosed in this utility model has multiple functions and good flexibility, and can meet the high-quality requirements of customers.

[0003] However, this device has the following drawbacks in use: 1. The light-emitting lens is fixed at the end of the cavity, lacking axial displacement design, making it difficult to dynamically adjust the beam focusing range; 2. It relies on the mechanical switching of multiple independent disks (first and second color discs, etc.), making it impossible to achieve gradual or rapid mixing effects, thus affecting the smoothness of the lighting effects. To address these drawbacks, we propose a film and television special effects light. Utility Model Content

[0004] The purpose of this utility model is to provide a film and television special effects light to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows: A film and television special effects light, comprising a light body, wherein the light body includes an outer cylinder, an adjustable lamp tube, a convex lens fixedly installed on the inner wall of the adjustable lamp tube, and an assembly assembly disposed between the outer cylinder and the adjustable lamp tube; The assembly assembly includes an assembly ring, a retaining ring fixedly installed on the outer surface of the assembly ring, a first external thread formed on the outer surface of the assembly ring, and a first internal thread formed on the inner surface of the assembly ring. The inner wall of the left end of the outer cylinder is provided with a second internal thread adapted to the first external thread, and the outer surface of the adjusting lamp tube is provided with a second external thread adapted to the first internal thread. The outer cylinder is equipped with a lighting assembly, including LED beads and a cooling fan fixedly installed on the inner wall of the outer cylinder, a rotating ring rotatably connected to the inner wall of the outer cylinder, a limiting ring fixedly installed on the left end of the rotating ring, a nut threadedly connected to the surface of the limiting ring, and a special effect light glass sheet snapped into the inner wall of the limiting ring.

[0006] Preferably, the inner annular surface of the nut is provided with a flange for limiting the displacement of the special effects lamp glass plate.

[0007] Preferably, the outer cylinder is provided with a drive assembly, including a mounting frame fixedly installed on the outer surface of the outer cylinder, a through groove opened in the inner wall of the mounting frame, a motor fixed in the mounting frame, a spur gear installed at the output end of the motor, and a gear ring fixedly connected to the right end of the rotating ring, the through groove communicating with the interior of the outer cylinder.

[0008] Preferably, the gear ring meshes with a spur gear through a through groove.

[0009] Preferably, the assembly ring achieves the disassembly of the outer cylinder and the adjusting lamp tube by separating the first external thread and the second internal thread.

[0010] Preferably, the adjusting lamp tube achieves axial displacement through a helical transmission between a first internal thread and a second external thread.

[0011] The film and television special effects light of this invention has the following advantages: 1. This film and television special effects light adjusts the axial displacement of the lamp tube by adjusting the screw drive of the lamp tube and the assembly ring, precisely controls the focal length change of the convex lens, and can adjust the beam focusing range (focusing / diffusing conversion) in real time, solving the defect of traditional fixed lenses that cannot be dynamically focused.

[0012] 2. This film and television special effects light adopts a rotating special effects light glass structure. The motor drives the gear ring to drive the special effects light glass to rotate continuously, realizing a dynamic mixing effect of light refraction / scattering. Compared with the traditional color disc mechanical switching method, it significantly improves the smoothness of special effects and the naturalness of color transition. Moreover, the modular design supports the quick replacement of different special effects light glass sheets, expanding the diversity of light effects. Attached Figure Description

[0021] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a film and television special effects light.

[0022] like Figure 1-6 As shown, a film and television special effects light of the present invention includes a light body, which includes an outer cylinder 10, an adjustable lamp tube 20, a convex lens 21 fixedly installed on the inner wall of the adjustable lamp tube 20, and an assembly assembly disposed between the outer cylinder 10 and the adjustable lamp tube 20.

[0023] The assembly assembly includes an assembly ring 30, a retaining ring 31 fixedly installed on the outer surface of the assembly ring 30, a first external thread on the outer surface of the assembly ring 30, and a first internal thread on the inner surface of the assembly ring 30. The inner wall of the left end of the outer cylinder 10 is provided with a second internal thread that matches the first external thread. The outer surface of the adjusting lamp tube 20 is provided with a second external thread that matches the first internal thread. The assembly ring 30 separates the outer cylinder 10 from the adjusting lamp tube 20 through the separation of the first external thread and the second internal thread. The adjusting lamp tube 20 achieves axial displacement through the helical transmission of the first internal thread and the second external thread.

[0024] The assembly ring 30 achieves dual functions through its internal and external double thread structure. After the first external thread on the surface of the assembly ring 30 is screwed into the second internal thread inside the outer cylinder 10, the outer cylinder 10 and the adjusting lamp tube 20 can be fixed together. The first internal thread inside the assembly ring 30 cooperates with the second external thread on the surface of the adjusting lamp tube 20 to form a helical pair. When the adjusting lamp tube 20 is rotated, the helical pair converts the rotational motion into axial linear displacement, thereby realizing the telescopic adjustment of the adjusting lamp tube 20.

[0025] Adjusting the axial displacement of the lamp tube 20 will change the focal position of the internal convex lens 21. Moving the lamp tube 20 forward can focus the light beam to form a strong light spot, while moving it backward will diffuse the light range. The amount of displacement is controlled by a precision thread to achieve a gradual change in light effect.

[0026] The outer cylinder 10 houses a lighting assembly, including LED beads 40 and a cooling fan 41 fixedly installed on the inner wall of the outer cylinder 10, a rotating ring 42 rotatably connected to the inner wall of the outer cylinder 10, a limiting ring 43 fixedly installed on the left end of the rotating ring 42, a nut 44 threadedly connected to the surface of the limiting ring 43, and a special effects light glass 45 snapped onto the inner wall of the limiting ring 43. The inner ring surface of the nut 44 is provided with a flange 46 for limiting the displacement of the special effects light glass 45. One end of the flange 46 is provided with a rubber buffer pad. After the outer cylinder 10 and the assembly ring 30 are disassembled, the internal lighting assembly can be exposed, so that the nut 44 can be unscrewed to replace different special effects light glass 45. The special effects light glass 45 is existing technology. When light penetrates a special thin film on the glass surface, it forms dynamic images or light spots (such as starry sky or water ripple effects) on the glass surface through a precise ratio of reflection and transmission. Therefore, it will not be described in detail.

[0027] The outer cylinder 10 is provided with a drive assembly, including a mounting frame 50 fixedly mounted on the outer surface of the outer cylinder 10, a through groove opened in the inner wall of the mounting frame 50, a motor 51 fixed in the mounting frame 50, a spur gear 52 mounted on the output end of the motor 51, and a gear ring 53 fixedly connected to the right end of the rotating ring 42. The through groove is interconnected with the interior of the outer cylinder 10. The gear ring 53 meshes with the spur gear 52 through the through groove, and the motor 51 drives the spur gear 52 to mesh with the gear ring 53, transmitting power to the rotating ring 42.

[0028] The rotating ring 42 drives the limiting ring 43 and the snap-fit ​​special effect light glass sheet 45 to rotate. The light from the lamp bead 40 is refracted and scattered by the dynamically rotating special effect light glass sheet 45. The flange 46 of the nut 44 is tightened and fixed to the special effect light glass sheet 45 by the thread to prevent axial displacement.

[0029] Working principle: Threaded connection fixation: Screw the first external thread of the assembly ring 30 into the second internal thread of the outer cylinder 10 until the retaining ring 31 fits against the end face of the outer cylinder 10, thus completing the fixation of the main structure.

[0030] Focusing control: Rotating the adjusting lamp tube 20 clockwise pushes it forward through the screw pair of the first internal thread and the second external thread, causing the convex lens 21 to focus the light beam into a strong light spot. Rotating it counterclockwise diffuses the light.

[0031] Light sheet replacement procedure: After removing the assembly ring 30, unscrew the nut 44 counterclockwise to release the flange 46 restriction, and then replace the special effect light glass sheet 45 that is snapped into the limit ring 43.

[0032] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
