Abstract
In one aspect, a light assembly configured to be installed in a movie theater projector includes an emitter housing with an LED emitter plate that emits a beam of light. The light assembly also includes a cooling assembly configured to dissipate heat from the LED emitter plate. The light assembly also includes a lens assembly configured to adjust the size or pitch of the beam with a concave adjustor having a concave lens configured to spread the beam emitted from the LED emitter plate and a convex adjustor having a convex lens configured to collimate light received from the concave lens. The concave adjustor is movably attached to the emitter housing and the convex adjustor, and the lens assembly is configured to be manipulated to adjust a distance between the concave lens and the convex lens, thereby adjusting the size or pitch of the beam.
