Technical Field

The invention relates to the field of stage lamps, in particular to a double-effect fruit tray mechanism of a stage lamp and an optical effect change control method of the double-effect fruit tray mechanism.

Background

In the field of stage light applications, the use of pattern effect discs has become very common. The light can produce light beams with different effects after penetrating through the pattern effect disc, has the light space feeling with rich patterns, and is deeply loved by stage lighting designers.

At present, the concept of dynamic pattern effect discs appears in the market, and the dynamic effect discs mainly realize special dynamic visual effects such as water ripples, flames, flowing clouds and the like. Generally, the dynamic effect pattern disc is provided with an oversized pattern effect disc and two motors, one motor controls the effect pattern disc to cut in and out a light path, and the other motor realizes the continuous rotation of the effect pattern disc. However, since the space of the optical axis direction occupied by the pattern effect disc is large, the structure is complex, one set of equipment can only use one pattern effect disc generally, and the interconversion of the dynamic visual effect of the same device cannot be realized, so that the changeable pattern effect is single and not abundant enough. In addition, the lens needs to be moved in a large range in order to adjust the patterns clearly, the cost is also increased in multiples, and certain trouble is caused to the design of the lamp.
