Abstract: A light fixture includes a housing, a light source, and a zoom mechanism. The light source is supported within the housing and emits light. The zoom mechanism selectively varies a beam angle of the light emitted from the light fixture and includes a lens and a movable element. The lens is fixed relative to the light source. The movable element is movable relative to the lens between a first position and a second position. The lens reflects a portion of the light emitted by the light source via internal reflection when the movable element is in the first position. The movable element is closer to at least a portion of the lens when the movable element is in the second position to at least partially frustrate the internal reflection.

Abstract: A cyc light assembly comprising a base having a front opening, a lighting element supported by the base, a first reflector (e.g., a specular reflector) positioned on a rear side of the lighting element, and a lens positioned in the front opening. The lens includes a plurality of cylinder lens portions that preferably are substantially parallel to each other and substantially horizontally oriented. A diffuser can be positioned to cover the front opening. In one embodiment, a central axis of the lighting element intersects the first reflector (e.g., at a midsection). A recycling reflector can be positioned in front of the lens, and side reflectors can be positioned on opposing sides of the lighting element. Preferably, the side reflectors are substantially planar and are angled to diverge from each other toward the front direction and toward an upward direction, away from the lighting element.

Abstract: A parabolic aluminized reflector (PAR) lighting fixture is provided with a faceted lens having many distinct lens elements. A plurality of first lens elements use light refraction to direct light from the collimated beam supplied from the fixture reflector to uniformly illuminate segments of a region of an adjacent wall surface. A plurality of second lens elements use internal reflection to direct light from the collimated beam to uniformly illuminate other, off-axis segments of the region. The resulting highly asymmetric beam distribution pattern provides wall wash or cyc capability with a widely available PAR fixture and eliminates the need for dedicated cyc or wall wash fixtures.
