Abstract
A reflector is provided which surrounds a light source that has emissions in both the visible and radio frequency ranges. The electrically conductive reflecting coating of the reflector is connected to the system electrical ground so that the radio frequency component is effectively shielded by the reflector. The visible component of the spectrum emitted by the source escapes the reflector cavity after at least one reflection from the reflector surface and forms the required beam pattern.
