Systems are provided a multi-lens device. In one example, the multi-lens device includes a volumetrically flexible compartment fluidly coupled to a gap between a first lens and a second lens of a lens assembly. The gap and the flexible compartment are hermetically sealed from outside of the lens assembly. A desiccant is positioned between the compartment and the gap.

Systems for multi-lens devices

A light fixture includes a lens, at least one light source emitting light towards an input side of the lens, a first compartment comprising a sidewall extending circumferentially around the lens, and a deformable membrane extending from the lens to a distal end of the sidewall. The lens is movable relative to the at least one light source. The first compartment is configured to house the at least one light source. The lens and the deformable membrane seal the first compartment from moisture, particles, or contaminants from outside the light fixture.

Examples are disclosed for systems and methods for providing an automated light show synchronized to one or more music files. In one embodiment, a method comprises generating a music feature file based on selected audio, the music feature file comprising metadata for the selected audio including a plurality of time markers indicating audio events in the selected audio, and automatically controlling one or more lights according to the music feature file. In another embodiment, other approaches and systems are provided to improve a light show or to provide structures and processed files which can be used to improve a light show or provide other features.

Systems and methods for a music feature file and coordinated light show

The present disclosure provides a light fixture which comprises a compartment configured to house at least one light source and a lens movably arranged relative to the light source. The light fixture further comprises a deformable membrane having a tubular shape extending from a first end to a second end and forming an inner cavity. The first end of the membrane is attached to the lens. The second end of the membrane is attached to a sidewall of the compartment. The sidewall is extending circumferentially around the lens.

A lighting fixture having at least one internal processor and at least one fixed element to which controllable moving elements are rotatably fastened, one moving element having at least one light source that generates a beam of light. Information concerning positions of moving components in a lighting fixture is automatically achieved. Correct position indication at start up is obtained without moving the components to their end stops for finding set points for step motors by the provision of at least one absolute encoding device, which encoding device indicates the angular movement of a first input axel in relation to the encoding device, which absolute encoding device has a gearbox with a second internal axel, which first input axle drives a first toothed timing wheel, intermeshing with a second toothed timing wheel that rotates the second axel with a angular velocity different from the angular velocity of the first input axle.
