Description

Technical Field

[0001] The utility model belongs to the technical field of stage atmosphere rendering, and in particular relates to a supporting component of a stage atmosphere rendering prop. Background Art

[0002] Stage atmosphere rendering props usually refer to special lighting devices used to create stage atmosphere and mood. These prop lights can use different lighting effects, colors and intensities to create different atmospheres and emotions through changes and combinations of lights, and create dreamy, mysterious or dramatic atmospheres through strong beams, smoke and color changes. Air lamps usually have strong light penetration and adjustable color effects. Special light projection equipment is used to project different patterns, shapes or texts on the stage to create a unique atmosphere and visual effects. By using color filters or beam splitters, white light is decomposed into different colors to create a colorful atmosphere. Laser beams generated by high-energy lasers are used to create fast-moving, flashing and changing light effects through special beam scanning and control technology to create a sense of movement and mystery. These props can be designed and adjusted according to the needs of the repertoire, helping the actors and audience on the stage to better immerse themselves in the plot and atmosphere.

[0003] The light, color and effects of mood lights can create various atmospheres such as fantasy, mystery, tension, romance, etc. through different combinations and changes. They can make the audience feel specific emotions and atmospheres through the brightness and darkness of lights, changes in colors, and the projection and diffusion of light. Mood lights can emphasize specific plots and scenes on the stage through the focus, projection and change of light, so that the audience's attention is more focused. For example, by using special lighting effects at critical moments to highlight a certain character or prop to reach the climax or turning point of the plot, mood lights can express the emotional state of the characters through the brightness and darkness of light, changes in color and dynamic effects of light. For example, use soft lights and gradient colors to express romantic scenes or the gentle emotions of characters; use strong light and flickering effects to express tense or intense plots. Mood lights can be combined with other stage elements (such as scenery, costumes, music, etc.) to enhance the stage effect through the projection and combination of lights. They can change the spatial sense, depth and visual level of the stage, making the stage more vivid, three-dimensional and attractive. In short, the mood lights for stage atmosphere rendering can create a variety of atmospheres and emotions through changes and combinations of lights, emphasize the performance of the plot and characters, enhance the stage effects, and enable the audience to better integrate into the plot and the stage world. The problems with the above-mentioned technology are: during use, the mood lights need to be used in combination with the support frame, but the mood lights need to be connected and fixed with the support frame through multiple fixings and connectors during the assembly process. The assembly process is relatively cumbersome, and it is not convenient for users to quickly connect and install the mood lights with the support frame. After the installation is completed, the illumination angle of the mood lights cannot be adjusted in time according to the use requirements, thereby reducing the flexibility of the use of the mood lights.
