Abstract: A light modifier for illuminating a subject using a combined modeling/strobe light source as the light source. This light assembly is attached to an adjustable focusing mechanism enabling the light to be projected either as a spot or a flood. The light is intended mainly for professional studio use, and is generally placed away from the camera.The main body of the light housing is molded of one piece plastic and attached to a yoke assembly by two adjustable knobs which control the vertical rotation of the light. The back of the housing is open with light-baffle plate preventing light from spilling from the rear of the housing, while allowing for free air circulation around the light-baffle plate. The design allows the unit to rotate 360 degrees around the yoke axis. It may be mounted on a light stand, or other support structures such as an overhead rack.The light is equipped with a fresnel lens molded of transparent plastic having the fresnel facets closely spaced on outside-facing (long conjugate) side.

Abstract: An adjustable lighting fixture has a power transfer means interposed between a lamp holder and the point of mounting. The power transfer means has an input shaft, which may be offset from the point of mounting, such as a fixture mounting pole, or in line therewith, and an output shaft which rotates in response to the rotation of the input shaft about its own axis. When the axis of power input is in line with the point of mounting, a physical rotation of the power transfer means will cause the rotation of the lamp holder about an axis extending through the point of mounting. When the axis of power input is offset from the point of mounting, an orbital input about the axis of the power input, or in other words an orbiting of the power input shaft about the axis extending through the point of mounting, will cause rotation of the lamp holder about said axis extending through the point of mounting.
