摘要： The invention relates to a low-pressure gas discharge lamp which includes at least one discharge vessel and at least two capacitive coupling-in structures and operates at an operating frequency f. In order to achieve a better efficiency in combination with a small structural volume, a high luminous flux, a low operating voltage, a low electromagnetic emission, a high resistance against switching transients and a long service life for the low-pressure gas discharge lamp, it is proposed to form each capacitive coupling-in structure from at least one dielectric having a thickness d and a dielectric constant ∈, each dielectric being subject to the condition d/(f.∈)

摘要： A gas discharge lamp with at least one capacitive coupling structure (2, 3) is described, which lamp has the particular characteristic that the coupling structure (2, 3) comprises a ceramic material which comprises pure BaTiO3. In particular an additional doping of at least part of the BaTiO3 with barium leads to a material whose Curie temperature and saturation polarization are substantially higher and whose coercitive field strength is substantially smaller, so that a gas discharge lamp with a coupling structure manufactured from this material can be operated at substantially higher temperatures and at a lower operating voltage. Various dopings of the BaTiO3 with titanium, manganese, and lead are furthermore described.
