While generation of aftergrow is thus assured sufficiently, with the pulse for securing the maximum duty ratio, a switching transistor is driven. Accordingly, the maximum efficienty of ultraviolet radiation is attained including the radiation of excimer beam of 172 nm, 158 nm and the radiation of 147 nm.

摘要： PROBLEM TO BE SOLVED: To provide a discharge lamp lighting device for preventing a cataphoresis phenomenon so as to form a straight discharge arc without any uneven coloring by modulating a first wave form signal for generating a modulating signal such that the polarity of the center line of the first wave form signal is alternately changed by a modulation frequency lower than an acoustic resonance frequency. SOLUTION: A circuit 28 generates a first wave form signal where a wave form has an acoustic resonance frequency for exciting a mode for making a discharge arc straight and the center line of the wave form is held at a fixed level. Each of circuits 16, 18 and 14 modulates the first wave form signal so as to alternately change the polarity of the center line of the first wave form signal by a modulation frequency lower than the acoustic resonance frequency and thereby generates a modulating signal. Thus, by a synthetic wave made between the wave form having the frequency component of the acoustic resonance frequency for exciting the mode for making the discharge arc straight and the wave form for changing its polarity by a frequency with the acoustic resonance frequency as an upper limit, a discharge lamp is lit without any uneven coloring of the arc.

摘要： PROBLEM TO BE SOLVED: To improve luminous flux retaining ratio and prolong the life by suppressing the reaction of mercury ion with phosphors and a glass tube and suppressing deterioration of the phosphors and mercury elimination. SOLUTION: This fluorescent lamp 1 comprises a lighting circuit 2 to start lighting, a light transmissive conductive film 3 which is an electric potential applying member installed in the surrounding of the discharge plasma generated in the inside of a fluorescent lamp, an electric power circuit 4 for applying electric potential to apply higher electric potential to the light transmissive conductive film 3 than that of the discharge plasma. The electric power circuit 4 for applying electric potential and the light transmissive conductive film 3 are connected to keep the potential of the light transmissive conductive film 3 higher than the discharge plasma, so that an electric field in the direction from the tubular wall of a glass tube composing the fluorescent lamp 1 to the center part is generated and the density of the mercury ion in the peripheral part of the tubular wall. Consequently, the reaction of mercury with phosphors and the glass tube is suppressed and deterioration of phosphors and mercury elimination are prevented and the life of the fluorescent lamp 1 is prolonged.
