METHOD FOR INCREASING THE EFFICIENCY OF A GAS DISCHARGE LAMP AND CONTROL OF ITS RADIATION SPECTRUM Russian patent published in 2021 - IPC H01J65/04 

FIELD: gas-discharge lamps.

SUBSTANCE: invention relates to a method for increasing the ECE ratio of gas-discharge lamps, which can be used as an energy source when pumping lasers for remote exposure to an object. On the emitting light and facing the object to be illuminated, the surface of the lamp body or on the outer and/or inner surface of the auxiliary transparent body having a shape corresponding to the lamp topology and located between the light emitting surface of the lamp body and the object to be illuminated, an optical multilayer is applied, at least two-layer, interference dielectric film broadband reflective coating with predetermined spectral properties of reflection and transmission of light from alternating layers with different refractive indices. A pulsed or constant voltage is formed on the lamp electrodes; excite a gas discharge; provide the occurrence of a discharge current; radiation by the plasma of a discharge of light with a wide spectrum of radiation, close to the spectrum of radiation of a black body; transmission by the coating of a predetermined spectrum range and reflection of the remaining ranges of the lamp emission spectrum by the coating into the discharge plasma of the lamp. In this case, additional heating of the discharge plasma by the returned light occurs, which leads to an increase in the temperature of the discharge plasma and to an increase in the glow intensity of the gas-discharge lamp in the preselected spectral ranges of its actual glow.

EFFECT: increasing the glow intensity (ECE ratio) of a gas-discharge lamp in a given spectral range.
