Non-equilibrium plasma formation as a lighting source

Summary form only given. The problem of high effective energy transformer source brought the need of applied properties investigations of serial and perspective plasma generators, which have the well known effectiveness of primary energy transformation into different kinds of energy; gasdynamics, heat, light, irradiation, electricity. Erosive plasma generators of supersonic plasma jets are characterized, by the jet self-focusing, high parameters of effectiveness of transfer into irradiation (10-20%) add the possible controllability of spectral constitution to allow them to be used as impulse powerful lighting source in visible spectrum range. We chose for our investigative research the electrodischarge erosive plasma accelerator and modified it to get an optimal total discharge energy (up to 1 kJ/spl Phi/). Its generated high-power plasma jet (specific energy up to 10 J/cm/sup 3/, electron density up to 10/sup -27/ cm/sup -2/, decay time up to 0.5 s) is characterized by the spatial structure along with some applied properties which reveals the high effectiveness of primary electric power transfer. There are several construction schemes of this generator at our institute with solid and liquid working substances of organic and polymeric origin. In the visible spectral range and near UV the proposed plasma formation has the specific intensity of lighting 10/sup 3/ times higher than that of the analogous nitrogen electrodischarge. As it is measured in our experiments the irradiation part in UV range for a solid erosion polymer is up to 40%, for liquid organics up to 55%.
