GAS-DISCHARGE LAMP FOR VISUAL LIGHT EMISSION, METHOD FOR ITS MANUFACTURING AND METHOD FOR ITS USE

摘要

FIELD: electrical engineering. SUBSTANCE: output power spectrum of gas-discharge lamp is controlled by alternation of density of filling medium in order to shift with keeping basically same shape. Gas-discharge lamp with sulfur or selenium operates under pressure of at least one atmosphere and is filled with medium which has low ionization potential voltage. Doping agents include materials with alkali metals, III B group metals and alkali-earth metals. When light is reflected back to bulb, emitted light has larger intensity in long- wave spectral region. EFFECT: at least one of following characteristics is improved: three-dimensional color uniformity, quenching and reliability of lamp ignition. 24 cl, 18 dwg, 4 ex
