Abstract
A housing for an elongate electrodeless bulb which is energiseable by an rf field such as a microwave field, preferably at or around 2.45 GHz. The housing is constructed of electrically conductive material and is arranged to have a substantially unobstructed opening through which the bulb is visible from outside the housing, and the housing is arranged to hold the bulb in a position which is recessed into the housing such that in use, the bulb is energized by virtue of its position within the housing and adjacent surrounding conductive parts of the housing substantially attenuate the rf field near the opening so that the rf field strength outside the housing is substantially zero whereby visible light or UV light is freely allowed out through the opening.
