FIELD: light sources. SUBSTANCE: light source is plasma excited by means of microwave energy. Plasma is excited in electrode-free quartz-glass bulb filled with mixture of inert gas (argon) and substance evaporating when plasma is excited. Plasma firing is effected by microwave energy in pulsed mode at pulse repetition rate exceeding energy of vision. EFFECT: reduced per unit cost of light flux when manufacturing light source.
