Definitions

  • the invention relates to an asymmetrically radiating lamp with a plurality of mirror optics arranged side by side in a housing, each for a rod-shaped lamp, in particular for use in spraying or painting booths.
  • Such lights with asymmetrical light distribution for uniform illumination of vertical or horizontal surfaces are known for various applications (DE-A-1 497 369, DE-U-85 07 634).
  • the luminaires each have a movable reflector or mirror optics to adapt the light emitted by the lamp to different lighting tasks. All of these luminaires have a fixed assignment of optics and luminaire housing. However, ideal lighting conditions, such as are necessary for painting and testing processes, cannot be achieved with the known luminaires.
  • the invention is based on the object of designing an asymmetrically radiating lamp in such a way that problem areas on spraying and painting objects such as, for example, motor vehicle bodies are optimally illuminated and that fewer lamps are required at the same time.
  • This object is achieved by the characterizing features of claim 1. Further developments and advantageous refinements of the invention are specified in the subclaims.
  • the luminaire has a box-shaped, elongated luminaire housing (1), which can be closed with a pane cover (2) on the front to meet the FF conditions required for spraying and painting booths.
  • a box-shaped, elongated luminaire housing (1) which can be closed with a pane cover (2) on the front to meet the FF conditions required for spraying and painting booths.
  • three mirror optics (3, 4, 5) are each arranged around a rod-shaped lamp (6), in particular a fluorescent lamp, the longitudinal axes of which preferably run horizontally.
  • Each mirror optic consists of a semicircular secondary mirror (3a, 4a, 5a) which merges into a parabolically curved, obliquely radiating deflecting mirror (3b, 4b, 5b).
  • Two mirror optics (3, 4) are preferably of the same design, while the third mirror optics (5) have a larger deflecting mirror (5b) with a more pronounced obliquely radiating characteristic. All mirror optics are delimited on both sides by end walls (3c, 4c, 5c), which stabilize the curved secondary and deflecting mirrors. At the same time, the end walls form bearing points of the mirror optics on two outside supporting parts (3d, 4d, 5d), which in turn are slidably and removably arranged in the lamp housing (1).
  • a socket (6a) is attached to receive the lamp base, the central axis of which also serves as the pivot or pivot point of the end walls and thus the mirror optics around the corresponding lamp.
  • the swivel range of the Mirror optics (3, 4, 5) from the basic position shown in solid lines to the maximum tilt position (3 ', 4', 5 ') shown in broken lines comprises about 30 ° in the smaller optics (3, 4), while in the larger optics (5) is slightly less.
  • the supporting parts are each assigned sheet metal angles (3e, 4e, 5e) with a graduation and several locking holes, as indicated in particular on the upper sheet metal angle (3e).
  • All 5 ° steps are preferably marked by a locking hole.
  • a spring bolt (3f) attached to the associated end wall snaps into the locking holes and holds the mirror optics in the set position.
  • semi-ring-shaped baffles (3g, 4g, 5g) are cut out in the end walls for stepless adjustment and locking of the mirror optics, through which two screws inserted into the corresponding support part engage. The latter clamp the front wall and thus the mirror optics in any position of the swivel range and thus ensure fine adjustment.
  • Each mirror optic together with its supporting parts, sockets and the lamp, forms a solid structural unit and is held removably on the side rails (7), only indicated, within the lamp housing (1).
  • the supporting parts (3d, 4d, 5d) of the individual mirror optics on the rails (7) can be moved in a sled-like manner transversely to the longitudinal axes of the lamps. This enables interchangeability of the optics within the luminaire and, in particular if the mirror optics are removed, any movement of the two remaining optics over the rail area.
  • the window cover (2) can be folded down on the hinges (2b) after loosening the locking bolts (2a) (Fig. 3).
  • the pane cover has a circumferential frame in which a two-pane safety glass (2d) is inserted as a light exit surface by means of a seal (2c).
  • the silicone-free processed seal lies firmly on the edge of the lamp housing (1) when the pane cover is closed and ensures compliance with the FF conditions.
  • a switch is also actuated by the window cover and cuts off the power supply to the electrical components of the lamp when it is opened.
  • the connection between the electrical components, for example the ballasts (8) arranged in series one behind the other, and the lamp holders via plug connectors takes place within the luminaire, so that the mirror optics can be easily exchanged in the manner described above.
  • the light distribution can be particularly advantageously optimally adapted to a specific lighting or test object, so that the problem areas of a painted body are also well illuminated.
  • the lighting options of the luminaire can also be used again - also through the use of newly developed optics.
