Description

Technical Field

[0001] The invention relates to the field of stage lights, and in particular to an infinitely rotatable stage light imaging system and a stage light thereof. Background Art

[0002] Stage lighting, also known as "stage illumination" or "lighting" for short, is one of the means of stage art modeling. Using stage lighting equipment (such as lighting fixtures, slides, control systems, etc.) and technical means, with the development of the plot, light color and its changes are used to display the environment, render the atmosphere, highlight the central characters, create a sense of stage space and time, shape the external image of the stage performance, and provide necessary lighting effects.

[0003] Stage lights usually include a base, an XY arm bracket, a lamp body shell mounted on the XY arm bracket, and an imaging system installed in the lamp body shell, wherein the imaging system includes a fixed bracket, an imaging platform mounted on the fixed bracket, an optical lens group, and a light source, etc. The light projected by the light source is cut and rotated by the imaging platform, and then projected out through the optical lens group.

[0004] In order to enrich the stage art effects and enhance the atmosphere, the imaging system of the stage light integrates a variety of effect components to obtain a variety of lighting effects. An important function of the imaging system is light cutting and rotation. Through the rotation of the imaging system, more complex and varied lighting effects can be achieved.

[0005] In the prior art, the imaging platform generally realizes the rotation function by relatively rotating the fixed bracket. However, each effect component on the imaging platform needs to be connected to the power supply circuit and the control circuit to work. Therefore, if the imaging platform rotates in one direction all the time, the circuits connected to the imaging platform will be twisted together, which may affect the service life of the circuits at the least, or even cause direct damage to the circuits, affecting normal use.

[0006] In some existing stage lights, a rotation limit structure is set on the fixed bracket and the imaging platform, or a rotation angle sensor and control system is installed to limit the relative rotation range of the imaging platform and the fixed bracket, in order to solve the problem of excessive twisting of the circuit during the rotation process. However, this structure is relatively complex and requires more mechanical and electronic structures to implement, which increases the production cost and failure rate of the stage light, and especially affects the use effect.
