Abstract
An apparatus and method for adjusting a high intensity discharge arc tube to a predetermined (e.g., relatively horizontal) operating position in a light fixture regardless of aiming orientation of the light fixture towards a target. In one aspect, the light source is mounted in an independently pivotal yoke in the light fixture. A mechanical linkage proportionally pivots the light source relative to any pivoting motion of the fixture over a range of positions such that a selected light source orientation can be approximately maintained regardless of aiming orientation of the fixture.
