  • Lamp housing
    Patent number: 6595661
    Abstract: An array of photo detectors or a ground glass is employed in concert with a beam-forming reflector to generate a positional error(s) as the light source is displaced from a reference location in the vertical plane. The beam is formed by means of a small hole through the reflector on its optical axis. These error signals are interpreted visually or introduced into electronic servo loops to mechanically drive the lamp assembly to an on-axis reference location. Provision is made to move the reflector along the optical axis to achieve co alignment of the reflected image of the arc source with its direct image.
    Type: Grant
