FIELD: lighting engineering.
SUBSTANCE: system has casing that accommodates magnetron-generated microwave transmitting waveguide whose output protrudes from casing, bulb disposed outside of waveguide output that radiates light by plasma generation with aid of microwaves transferred through waveguide, resonator with its gauze part that prevents microwave dissipation and transmits light produced from bulb, and reflector mounted on waveguide output end for reflecting light generated in bulb and provided with heat-protection part made in the form of non-gauze structure to organize resonating region.
EFFECT: enhanced service life and light intensity.
