Definitions

  • the invention relates to a high-pressure discharge lamp with a base and associated socket, the lamp having two electrodes arranged on the longitudinal axis and on opposite sides of the discharge vessel, each with an associated power supply and a fusing surrounding it.
  • the lamps described here are preferably used in luminaires for film and video recordings as well as for stage lighting and for similar purposes. In addition, these lamps can also be used, for example, for projection purposes or for general lighting.
  • the lamps were provided with a base at each melting point.
  • the installation length is accordingly large, which is why the lamps had to be installed in the associated reflectors transversely to the longitudinal axis of the reflector.
  • a high voltage of up to 30 kV is required to re-ignite these lamps, which are still warm from operation. Given the short distance between the power supply lines, the base and socket contacts, this high voltage leads to flashovers and, under unfavorable circumstances, even to the destruction of the high-quality lighting parts.
  • the object of the invention is to provide a compact high-pressure discharge lamp with base and associated socket part, which is also suitable for hot ignition, and which is suitable for installation in reflectors.
  • the amount of light emitted by the lamp should not be reduced by reflector cutouts.
  • the high-pressure discharge lamp with base and associated socket with the features mentioned in the preamble of the main claim is characterized in that a base having two contact elements made of a high-voltage insulating material is fastened to only one melting point, the power supply facing the base directly with the first contact element and the Power supply facing away from the base via an electrical conductor is connected to the second contact element and also the contact elements are at least partially surrounded at a certain distance by a collar made of a high-voltage insulating material, and that the socket also consists of a high-voltage insulating material and has two connecting elements, the first ends of which for the non-positive reception of the contact elements of the base are provided and the second ends of which have a connection option for a supply voltage, the connecting elements being separated by a web projecting from their first ends to beyond their second ends, on each of which the connecting elements at least partially form a certain distance and form a cavity surrounding collar is molded from a high voltage insulating material.
  • the lamp is advantageously an AC-operated metal halide lamp without an outer bulb, which is particularly suitable for small, handy film and video recording lights as well as reportage lights due to its compact design and one-sided base.
  • both the base and the socket can be siliconized or glazed.
  • a high-pressure lamp without halogen additives or an inert gas lamp can also be used.
  • the contact elements are designed as pins and the connection elements as sockets and fastened at a distance D from one another to the associated molded body of the base or the socket.
  • the distance D corresponds to a maximum of 0.8 times the maximum ignition voltage (kV) to be applied for an operating war men lamp.
  • the pins are surrounded by cavities forming cavities at a certain distance over at least their entire length.
  • the collar surrounding the high-voltage contact element advantageously surrounds it over the entire circumference. This provides adequate insulation of the contact elements from one another, which is required against a flashover of the high voltage during the hot ignition of the lamp. To ensure correct lamp polarity, the collars also have a different cross-section.
  • the power supply of the lamp facing away from the base is advantageously connected to the second contact element of the base via a flat, preformed, rigid metal band, for example made of nickel-plated copper, the narrow end of which is facing to reduce the heat absorption of the lamp.
  • the large surface of the metal strip radiates a large part of the heat generated.
  • the melting of the lamp fastened to the base is fastened in an opening arranged centrally in the shaped body and / or surrounded by a collar which extends at a certain distance at least in the direction of the metal strip.
  • the total length L 1 resulting from the depth of the opening and the height of the collar is at least as great as the distance D. It is sufficient if this collar only surrounds the relevant melt approximately in a semi-circle to the opposite pole.
  • the connecting elements designed as sockets are also fastened to the socket at a distance D from one another and receive the contact elements in a force-fitting manner.
  • the plug connection between the pins of the base and the sockets of the socket can expediently be provided with a pull-off protection.
  • the width B of the web is preferably at least 1.0 D.
  • the connecting element carrying the high voltage is again advantageously surrounded by the collar over its entire circumference.
  • a collar which does not completely surround this is sufficient for the connecting element carrying the operating voltage.
  • the collars surrounding the connection elements of the socket have at least partially different cross-sectional shapes.
  • the cross-sectional shape of corresponding contact and connection elements on the base and on the socket is adapted to one another.
  • the socket is also provided with elements for fastening in a lamp. Due to the high thermal load, both the base and the socket are made in one piece from a heat-resistant and high-voltage insulating material, such as ceramic.
  • a metal halide lamp 1 with a base on one side is shown in FIGS. 1 to 3.
  • the two electrodes 2 and 3 are arranged on opposite sides of the discharge vessel 4, each electrode 2 and 3, respectively, having a melt 7 and 8 surrounding the associated power supply lines 5 and 6.
  • the meltdown 7 is fastened to a base 11 having two contact pins 9 and 10.
  • the power supply 5 facing the base 11 is directly electrically connected to the contact pin 9, while the electrical connection of the power supply 6 facing away from the base 11 to the contact pin 10 takes place via a flat, preformed, rigid, nickel-plated copper strip 12, whose narrow side faces the lamp 1. Good heat radiation is achieved by the nickel-plated copper strip 12 during lamp operation.
  • the distance between the discharge vessel 4 of the lamp 1 and the nickel-plated copper strip 12 is approximately 5 mm.
  • the metal halide lamp 1 is operated at 220 V / 50 Hz and in the present example has a power consumption of 250 W at a lamp voltage of 45 V.
  • a voltage of 20 kV to a maximum of 30 kV is required for the ignition, in particular for the re-ignition of the warm lamp .
  • This high voltage is applied to the lamp 1 via the contact pin 9.
  • the two contact pins 9 and 10 are therefore arranged at a distance D of 19 mm from one another and are completely surrounded over a little more than their length by a collar 15 and 16 forming a cylindrical cavity 13 and 14.
  • the position of a reflector R to the metal halide lamp 1 - e.g. in a film or video recording lamp - is indicated by dashed lines in FIG. 3.
  • the collar 15 surrounding the high-voltage contact pin 9 is cylindrical on its outer surface, whereas the outer surface of the collar 16 has a flat surface on the inner side facing the opposite pole.
  • the melting 7 fastened to the base 11 is in one certain distance in the direction of the copper strip 12 surrounded by an approximately semicircular collar 17.
  • the height of the semicircular collar 17 is 10 mm.
  • the melting 7 is additionally arranged in a round opening 18 in the central part of the base body.
  • the total length L 1 resulting from the height of the collar 17 and the depth of the opening 18 is approximately 23 mm.
  • the base body is further provided with corresponding openings 19 and 20.
  • the mechanical and electrical connection of all metal parts - the contact pin 9 with the power supply 5 on the one hand and the power supply 6 with the nickel-plated copper strip 12 and the contact pin 10 on the other hand - is expediently carried out by brazing or spot welding in order to achieve sufficient heat resistance during lamp operation.
  • the assembly preassembled in this way is inserted into the base body.
  • the remaining cavities of the openings 18, 19 and 20 are then filled with a heat-resistant and high-voltage insulating putty (not shown), which then hardens to the base 11 after the lamp has been adjusted.
  • the socket 21 suitable for the metal halide lamp 1 with a base on one side is shown in more detail in FIG. 3 and the corresponding socket body in FIGS. 7 to 10. Like the base body, the socket body is made in one piece from ceramic.
  • the two connection sockets 22 and 23 corresponding to the contact pins 9 and 10 of the base 11 and arranged at a distance D of 19 mm from one another are for isolation from one another by a web 24 separated, which extends beyond the connecting elements on the underside by a length L 2 of 13 mm.
  • the protruding length L 2 of this web 24 should be at least 0.5 times the distance D.
  • B the maximum width of the socket 21
  • the connection socket 22 carrying the high voltage is completely surrounded by a collar 25 over its entire length at a certain distance.
  • the corresponding counter bushing 23 has only one collar 26 which is open to the outside.
  • a cavity 27 and 28 is provided between the connection sockets 22 and 23 and the associated collar 25 and 26.
  • the collars 25 and 26 are designed differently to ensure correct polarity of the lamps and the shape of the corresponding collars 15 and 16 of the base body is adapted: the collar 25 has a round shape, whereas the collar 26 indicates the side facing the opposite pole has the flat surface of the web 24.
  • connection sockets 22 and 23 are provided on the underside with a threaded attachment, to which the supply lines 31 and 32 are connected by means of a nut 29 and 30, respectively.
  • the high-voltage connection socket 22 is direct attached to the socket body, while the connection socket 23 is screwed to the latter via a contact plate 33.
  • This contact plate 33 has a trapezoidal shape, the longest side of which faces the open side of the collar 26.
  • the open collar 26 ensures good cooling of the contact plate 33, for example by means of a fan (not shown) installed in the device housing.
  • other types of attachment of the sockets 22 and 23 in the socket body are also possible.
  • the openings 34, 35 and 36 in the socket body are provided for fastening the connection sockets 22 and 23.
  • the base body 21 is provided with cutouts 39, 40 and 41 for the cable lugs 37 and 38 fastened to the supply lines 31 and 32.
