Definitions

  • the invention relates to a socket for a single-ended high-pressure discharge lamp, consisting of a lampholder body made of a heat-resistant, electrically insulating material and two contact elements fastened to the lampholder body, each of which has a contact end receiving the contact counterpart of a lamp base and a connection end provided with a connection for a supply voltage .
  • the object of the invention is to design the socket in such a way that it enables the lamp to be positioned well within a reflector or an optical system with small geometric dimensions.
  • the version should also have a small mass with smaller geometric dimensions to reduce heating.
  • at least the same advantageous values should apply to the electrical data, in particular the high-voltage strength, as to the known version.
  • the contact elements should be protected against accidental contact by the user and against flashovers and also against high voltage spraying.
  • the socket for a single-sided high-pressure discharge lamp with the features mentioned in the preamble of the main claim is characterized in that the socket body is divided into two chambers separated from each other by a wall, in each of which a contact element is fastened, the chambers having access openings to the contact ends and to have the connection ends.
  • the contact elements are closed on almost all sides and contact by the user is excluded.
  • the fact that the distance between the contact ends is smaller than that of the connection ends, in particular that the longitudinal axes of both contact elements lie in a straight line and are arranged at right angles to the longitudinal axis of the lamp to be accommodated, gives the socket body a surprisingly low shape.
  • the shooting direction the contact ends for the contact counterparts of a lamp base coincide with the longitudinal axis of the lamp to be received, so that the electrical connection between the lamp and the socket is accomplished by a simple plug-in movement in one direction.
  • the contact elements are advantageously designed as leaf springs, which are particularly conducive to a flat design of the socket body.
  • One of the contact ends lies directly in the longitudinal axis of the lamp to be accommodated.
  • This contact element is arranged in an access opening designed as a centering receptacle with a cylindrical, in particular rectangular, cross section.
  • the centering receptacle On the side facing away from the lamp to be accommodated, the centering receptacle is provided with an adjoining depression with a smaller, essentially circular cross section. This recess increases the flashover resistance of the socket in connection with the lamp when a high voltage is applied, since less dirt can accumulate on the edges and corners.
  • the chambers on the side facing the lamp are provided with covers which are arranged at right angles to the longitudinal axis of the lamp and serve as a support surface for corresponding surfaces on the lamp base.
  • the version 1 of Figures 1 and 2 consists of the socket body 2 made of ceramic.
  • the socket body 2 contains a first chamber, which is subdivided by a rib 3 into a partial chamber 4 and a centering receptacle 5, and a second chamber 6. Both chambers 4 with 5 and 6 are separated from one another by a wall 7.
  • a contact element 8 and 9 is arranged within each of these chambers, each of the contact elements 8 and 9 having a contact end 10 and 11 and a connection end 12 and 13.
  • the contact elements 8 and 9 are designed like leaf springs and have a shape at their contact ends 10 and 11 in order to accommodate a corresponding contact counterpart of a lamp base.
  • connection ends 12 and 13 the high-voltage insulated cables 14 and 15 of a supply voltage are fastened, which are guided through access openings into the sub-chamber 4 and the second chamber 6.
  • the partial chamber 4, in which the connection end 12 of the contact element 8 is arranged, is completely closed by a cover 16.
  • a second cover 17 covers - leaving only one access opening 18 for the contact end 11 underneath of the contact element 9 - almost the entire chamber 6.
  • the two covers 16 and 17 are made of ceramic or mica and together form a plane that serves as a support surface for the lamp base, thereby creating a defined Positioning the lamp in a reflector or an optical system is guaranteed.
  • the contact end 10 of the contact element 8 is arranged with its receptacle directly on the longitudinal axis of the lamp within the centering receptacle 5.
  • This contact element 8 is provided for the connection of the high voltage.
  • the cross section of the centering receptacle 5 is matched to that of the centering pin of a corresponding lamp base and has a rectangular cross section, to which an approximately circular depression 19 adjoins in the lower region of the socket 2.
  • FIG. 3 shows a lamp 20 inserted in the socket 1.
  • the lamp base 21 lies on the plane formed by the covers 16 and 17, which enables a good adjustment of the lamp 20 in the reflector 22 of a lamp or in an optical system.
  • the version described here is preferably intended for a metal halide high-pressure discharge lamp, although high-pressure discharge lamps without halide additives or noble gas lamps can also be used.
  • the lamp is operated in particular at a square-wave voltage with an open-circuit voltage of more than 250 V, which makes the arrangement particularly suitable for film and television recordings without flicker effect.
  • An ignition voltage of up to 25 kV is required for lamp ignition, especially for immediate re-ignition.
  • the contact elements 8 and 9 of this version 1 are securely insulated against this high ignition voltage, so that flashovers cannot occur. Because of the small version and with it interacting lamp results in a robust, compact luminaire construction, easy lamp replacement and good focusability of the lamp light within the luminaire.
