  • Patent number: 7045938
    Abstract: The invention relates to a reflector lamp and to a method for producing such a reflector lamp, especially a simplified method for fixing the lamp (2) in the reflector (1). The gasket (22) of the lamp base (21) is disposed in the cavity (13) of the reflector neck (12) in such a manner that the at least one power lead (71, 72) projects from the reflector neck (12) through a passage and the lamp base (21) is supported on the inner wall (13) of the reflector (1) perpendicular to the longitudinal axis (A). A fastening element (81, 82) is fastened on the power lead (71, 72) at an angle to the longitudinal axis (A) and rests against the outer wall of the reflector neck (12). The lamp (2) is thus fixated in the reflector (1) in the longitudinal direction (A) without play and without any additional spring elements.

  • Patent number: 7030564
    Abstract: A low-pressure discharge lamp is described having a base housing (10), a discharge vessel (2), whose end sections are fixed to an end section of the base housing, and a contact-making system for making electrical contact with the lamp, which is located on the end section of the base housing (10) which is remote from the discharge vessel, a conductive section (5) being provided, which is electrically connected to the contact-making system and is arranged adjacent to the discharge vessel (2) in the base housing (10) in such a way that an electrical short circuit is formed around the discharge vessel (2). This makes it possible to reduce the starting voltage of the lamp. As an alternative, or in addition, to this, the cross section of the web attachments is increased, which also increases the rate of the luminous-flux run-up.

  • Patent number: 7025472
    Abstract: A coupling element (2) is proposed for the combining of at least two elongate lamps with in each case two ends. For this purpose, the coupling element (2) has a continuous receptacle area which is provided for receiving an end of each lamp. The receptacle area comprises a reflector (6) in order to reduce the luminance decrease in the region between the lamp ends. With one or a plurality of coupling elements according to the invention in conjunction with two or more elongate lamps, illumination systems having different luminous lengths can be realized in a modular manner.

  • Patent number: 6976898
    Abstract: The invention relates to an improved method of production for a flat radiator discharge lamp designed for dielectrically impeded discharges, in which, during a filling step for the discharge vessel, a plate of the discharge vessel is jacked up on parts, later softening, of support elements in order to be lowered onto the other plate at a specific temperature. In this case, the support elements serve, in addition, to improve the mechanical stability of the finished flat radiator. According to the invention, only a small number of the support elements present in a relatively large number are used for the outlined function of holding up the plate.

  • Patent number: 6976896
    Abstract: A process for producing a discharge vessel of a flat gas discharge lamp, in which the discharge vessel has a base plate (1), a frame (3) and a cover plate (2), as well as at least one spacer (6) between base plate (1) and cover plate (2). At least between one of the plates (2) and the frame (3), at least one space (6) is initially kept open as a filling opening. By partial fusion of at least a part (4, 5) of the frame, which may also comprise a layer (4) of soldering glass and local elevations (5), the filling opening (6) is eliminated after the filling operation. The distance between the vessel plates (1, 2) is defined by the spacers (7), which remain hard even during the joining operation.
