A glare control lamp and reflector assembly and method for glare control which includes a conventional lamp and symmetrical reflector for providing a controlled light beam to a target area. A reflector shield can be positioned on the reflector below the lamp and has the properties of diverging incident light downwardly towards the target area and thus controls reflection upwardly which would produce glare. A glare shield can be positioned on the top of the reflector and extends outwardly from the outer edge of the reflector to block both direct light and reflected light from traveling upwardly and outwardly which would produce glare. In a further combination, a lamp shield can be positioned over a portion of the outermost extending end of the lamp to prevent unreflected light from directly causing glare. The method for controlling glare includes the steps of providing a conventional lamp and reflector assembly, positioning a reflector shield in the bottom of the reflector beneath the bulb to coverge instant light downwardly to the target area, and providing a glare shield extending around and outwardly from the top of the reflector to block and divert incident light downwardly towards the target area. An additional step would be to provide a lamp shield over the outwardmost end of the lamp to block directly emanating light from causing glare. A still further feature and embodiment of the invention includes an arc shield which is positioned directly adjacent to the arc of the arc lamp used with the glare control lamp and reflector assembly. The arc shield serves to block and redirect light from a short distance from the arc in an accurate and efficient manner without much loss of useful light. The arc shield can be used individually or in combination with any of the reflector shields, glare shields, and lamp shields.
