Abstract: 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 null, each dielectric being subject to the condition d/(f.null)

Abstract: Arc tube (10) has a bulbous body (12) with a hollow center portion (14) and opposite ends (16, 18). Each of these ends has a cylindrical terminal-receiving section (20, 22) extending therefrom. The hollow center portion (14) has an internal length A and an internal diameter B that provides an aspect ratio of less than 5 and an outer surface area to inner surface area ratio, measured in square units, of less than 1.5. Electrodes (24) and (26) are hermetically sealed in the terminal-receiving sections (20, 22). The lamp uses less than 7 mgs of mercury. The low pressure operation allows the use of the arc tube in lamps without a shroud and the low mercury allow the lamp to pass TCLP requirement and be conventionally landfilled.

Abstract: A short arc discharge lamp has improved starting properties in which there is no danger of damaging the arc tube that surrounds a discharge space and in which the radiant light from the arc tube is not adversely shielded. This is achieved by providing the short arc discharge lamp with a first electrode having an electrical potential and to which a high voltage is applied, and a second electrode opposite the first at a in spaced relationship. Additionally, in the discharge space, there is positioned at least one conductive component with a tip projecting into the discharge space. The conductive component has an electrical potential which is identical to the electrical potential of the first electrode and has a tip spaced a distance from the second electrode which is greater than the distance between the first and the second electrode.

Abstract: Since an internal surface of an arc ball receiving recess, which greatly affects the shape of an arc ball, is formed in an arcuate cross section swelling outward, the arc ball can be formed so as to be received in the arc ball receiving recess in front of a focusing opening of a slit shape, whereby the arc ball can be formed in a well-regulated form. Therefore, the arc ball with uniform luminance distribution in the longitudinal direction of the slit focusing opening can be made with certainty in the arc ball receiving recess.
