Abstract: A nonelectrode RF light source of directional radiation which is an optically transparent bulb filled with a discharge gas, holding a starting inductor having turns of a monotonically decreasing diameter. For its whole length and shape, the inductor is enclosed in an insulating tube whose inner surface has a coating acting as an optical reflector. The said light source produces a discharge with luminous and spectral characteristics constant with time and uniform in spatial distribution.
