Title:

COMBINED TYPE DYNAMIC EFFECT DISC AND STAGE LAMP HAVING SAME

Document Type and Number:

WIPO Patent Application WO/2020/155847

Kind Code:

A1

Abstract:

A combined type dynamic effect disc and a stage lamp having same. The combined type dynamic effect disc comprises a light source and an effect disc bottom plate (1); a light through hole (7) and multiple pattern seats (4) are provided on the effect disc bottom plate (1); pattern pieces (5) are provided on the pattern seats (4); a first rotating assembly and a second rotating assembly are provided at the center of the effect disc bottom plate (1); the effect disc bottom plate (1) is driven to rotate by means of the first rotating assembly, so that different pattern seats (4) or the light through hole (7) may cut in or cut out from a light beam; a driven assembly is provided on the pattern seat (4), and the driven assembly is connected to the second rotating assembly in a matching mode and driven by the second rotating assembly to rotate, so that the pattern piece (5) is driven to rotate. The size of an effective pattern on the pattern piece (5) is greater than the size of an effective light spot generated after the light beam passes through the pattern piece (5); when the pattern piece (5) cuts into the light path, the pattern piece (5) forms a dynamic pattern effect in the rotating process. The combined type dynamic effect disc can achieve the beneficial effect of freely switching between multiple dynamic pattern effects under the driving of the same set of driving structure.
