Definitions

  • the invention relates to a rotationally symmetrical high-performance headlamp for metal halide lamps according to the preamble of claim 1.
  • a rotationally symmetrical high-performance headlamp for metal halide lamps of the generic type is previously known from DE 30 40 583 C 2. Replacing the metal halide lamps after removing the rear housing cover is extremely difficult, especially when arranging the high-performance headlamp on floodlight masts of up to 50 m in height, since the lamp is still live, even when the housing cover is removed, so that the lamp is not safe can be changed.
  • the invention is therefore based on the object of a rota tion-symmetrical high-performance headlights for metal halide lamps in such a way that the arranged in the axis of rotation of the reflector and this penetrating in a central opening metal halide lamp is arranged easily replaceable.
  • the slide-tilt mounting allows on the one hand that the metal halide lamp located in the axis of rotation of the reflector is first pulled backwards out of the reflector by a certain area by means of the housing cover, which region is just sufficient to then fold the housing cover together with to enable the metal halide lamp, without this then hitting the edge areas of the central opening of the reflector.
  • the metal halide lamp can be easily replaced.
  • the housing cover with the new metal halide lamp can first be folded up and then pushed back onto the rear side of the housing of the high-performance headlight, the metal halide lamp being axially displaced in the axis of rotation of the reflector.
  • a rotationally symmetrical high-performance headlight for metal halide lamps which has a rear housing cover which is mounted on the housing so that it can be folded down.
  • the metal halide lamp is installed transversely to the axis of rotation of the reflector and socketed in the housing cover.
  • the housing cover is folded around a lower, horizontal axis.
  • the disadvantage here is that the two ends of the metal halide lamp containing molybdenum foils receive reflections from the reflector, since both ends are arranged within the reflector. This heat radiation destroys the molybdenum foils at both ends of the lamp.
  • the metal halide lamp in the rotationally symmetrical high-performance headlamp according to the invention is located in the axis of rotation of the reflector, only a one-piece reflector with a small central hole opening being required.
  • the one-piece reflector has the highest possible degree of efficiency, since a 100% concentration of the light radiation is possible in the main light distribution of the lamp.
  • Both molybdenum foils of the lamp ends receive no reflections from the reflector, since the rear end of the lamp is arranged outside the reflector in the rear housing cover and the front end of the lamp in the large opening area of the reflector, with light and heat radiation parallel to the molybdenum foil Squeeze points passed without causing heating.
  • a switch and a contact piece are arranged between the housing opening and the housing cover.
  • This requires a contactor to switch off the voltage supplied via the supply line so that the metal halide lamp is de-energized.
  • the contactor is regularly outside the headlight and therefore requires a separate supply line.
  • the supply line must be electrically disconnected from the housing cover to the high-voltage devices of the High performance headlights to maintain.
  • the rear housing cover can be removed from the housing after being pulled out and folded down without further activities and removed from the high-performance headlamp for maintenance work.
  • the rotationally symmetrical high-performance headlamp for a metal halide lamp 1 comprises a truncated cone-shaped housing 2, a parabolic reflector 3 arranged therein, a front cover plate 4 and a rear housing cover 5 and a lamp base 6 fastened therein for the lamp 1.
  • This has a lamp bulb 7 and two thin lamp ends 8, 9 containing molybdenum foils, of which the rear lamp end 8 is inserted directly into the lamp base 7 and the front end, pointing towards the cover plate 4
  • Lamp end 9 is held on a power supply rod 10, which is also mounted in the lamp base 6.
  • the lamp 1 is arranged with its longitudinal axis in the axis of rotation 11 of the housing 2 and the reflector 3 and penetrates the reflector 3 at the rear end within an opening 12 which is just large enough that the lamp 1 together with the power supply rod 10 in the direction of Rotation axis 11 can be inserted.
  • the frustoconical, rotationally symmetrical housing 2 comprises a cylindrical end region 13 to which the correspondingly cylindrical rear housing cover 5 is attached in a sealed manner.
  • the end region 13 carries in the horizontal transverse axis two pivot bearings 14, with which the housing 2 is mounted on the arms 15 of a fastening bracket.
  • An electrical lead is passed through an opening 16 in the end region 13 and then connected to a socket 18 in the housing 2 in the region of the rear housing opening 17 for the housing cover 5.
  • a plug 19 is inserted with its connector pins 20, which are electrically connected to the contacts for the lamp 1 in the lamp base 6 within the housing cover 5.
  • the rear housing cover 5 is in the plane by means of two the locks 21 located on the pivot bearing 14 are fixed to the housing 2 and, after the locks 21 (FIG. 4) have been folded down, can be folded away from the housing 2 by means of a slide-tilt bearing 22.
  • bearing pins 23 are inserted in the plane of the pivot bearing 14 in the area of the closures 21 into the end face of the housing cover 5 directed towards the housing 2, the bearing pins 23 running parallel to the axis of rotation 11 and engaging in sockets 24 which engage in the rear end face of the housing opening 17 are trained (Fig.4).
  • the connector pins 20 of the connector 19 are arranged in the housing cover 5 parallel to the bearing pins 23 and to the axis of rotation 11, the connector pins 20 engaging in correspondingly aligned contact terminals of the socket 18 which is arranged in the housing opening 17.
  • the slide-tilt bearing 22 further comprises two angled hinge arms 25 fixedly attached to the underside of the housing cover 5, which have parallel hinge parts 26 at their free ends, which are provided with elongated holes 27.
  • the hinge parts 26 and the elongated holes 27 run parallel to the axis of rotation 11 and thus to the bearing pins 23, but at a radial distance which is greater than half the radius of the housing cover 5.
  • guides 28 for the hinge parts 26 In the lower region of the housing 2 there are guides 28 for the hinge parts 26 provided which guides 28 on the rear part carry bearing pins 29 which engage in the elongated holes 27 of the hinge parts 26.
  • the upper sides 30 of the guides 28 serve for the sliding contact of the hinge parts 26.
  • the rear housing cover 5 To replace the lamp 1, the rear housing cover 5 must be removed from the housing 2.
  • the two closures 21 located in the plane of the pivot bearings 14 are first released from the housing cover 5, as shown in FIG.
  • the housing cover 5 is then pulled backwards in the direction of the arrow 31 (FIG. 3), the bearing pins 23 of the housing cover 5 guided in the sockets 24 forcing the housing cover 5 to be guided in the direction of the axis of rotation 11 in parallel, so that the lamp 1 , which is located in its end position inside the reflector 3 (FIG. 1), with its thickest section in cross section, is completely pulled out of the opening 12 of the reflector 3 to the rear.
  • the plug pins 20 of the plug 19 are pulled out of the associated contacts of the socket 18, as shown in FIG.
  • the upper edges of the hinge parts 26 are guided along the upper sides 30 of the guides 28 until the bearing bolts 29 have reached the end of the elongated holes 27 (FIG. 3). 5 can now be folded down in the direction of the arrow 32 from the housing 2, the bearing bolts 29 serving as the axis of rotation for the housing cover 5.
  • the foremost lamp end 9 of the lamp 1, which is connected to the end of the current carrying rod 10, is guided on a radius which is shown in FIG. 5 with the dashed lines 33 which are just inside the rear opening 12 of the reflector 3.
  • the lamp 1 can now be easily replaced, the electrical power supply to the lamp base 6 having been disconnected even before the rear end position of the housing cover 5 according to FIG. 3, so that the lamp 1 is completely dead.
  • the lamp 1 is reinserted in the opposite manner by pivoting the lamp 1 into the housing and by axially pushing the housing cover 5 onto the housing 2 while simultaneously establishing the electrical connection between socket 18 and plug 19 and then locking the housing cover 5 by means of the closures 21.
