Definitions

  • the invention relates to a lighting device having a housing for mounting on a wall and with a plurality of arranged in the housing, parallel to each other and parallel to the wall provided for mounting extending rod-shaped light-emitting means for receiving bulbs, along each individual rod-shaped light-emitting device on this plurality of lamps are mounted side by side in such a way that they all point in the same direction and radiate transversely to the longitudinal direction of the rod-shaped lamp-carrier device.
  • Such lighting devices are known from the prior art. Such a lighting device is usually mounted as a ceiling light in a room and usually set up so that all bulbs present in it are directed vertically towards the floor of the room. Accordingly, there is a symmetrical distribution of the light emitted by such a known lighting device. The area immediately under the lighting device is thereby illuminated substantially uniformly, while areas laterally receive less light.
  • the luminous intensity distribution of the light emitted by the illumination device is symmetrical with respect to an axis tilted to the left or to the right with respect to the mid-perpendicular of the illumination device, this axis in turn has a certain angle to the table surface. Because of the fanning of the light on its path from the illumination device, this results in the less light arrives on the table per unit area the farther the area unit is away from the illumination device.
  • the upper part of the painting is provided in this lighting situation with more light per unit area, as the lower part of the painting, so that there is an overall uneven illumination of the painting.
  • the reason for this is the fanning of the light on its way away from the lighting device.
  • the greater the distance from the illumination device the less light there is per unit area. Accordingly, since the light which strikes the upper part of the painting had to travel a shorter distance than the light which strikes the lower part of the painting, the amount of light available per unit area is different, and the greater the greater the length of the image is in the vertical direction.
  • the invention is therefore based on the object, the lighting devices described above in such a way that a lighting device is provided, which is also capable of a longer or larger object, which is located at a certain distance from the lighting device and parallel or possibly under is arranged at a certain angle to the lighting device to illuminate evenly. Furthermore, the invention has for its object to provide a set, which consists of such a new lighting device and a specific adjustment for this particular.

  • the rod-shaped luminous means carrier device 1 shown here, several illuminants 2 are arranged side by side in a row. The bulbs 2 are mounted so that they all point in the same direction and radiate transversely to the longitudinal direction of the rod-shaped light source carrier device 1.
  • Fig. 2 which shows a schematic side view of the rod-shaped luminous means carrier device 1 of FIG Fig. 1 represents.
  • each individual luminous means 2 The distribution of the light intensity I emitted by each individual luminous means 2 relative to the respective local axis is symmetrical on each line orthogonal to the main optical axis of the luminous means 2. Accordingly, there is also a symmetrical Light emission of each individual of the rod-shaped illuminant-carrier devices 1.
  • the present invention thus dispenses with the use of asymmetric reflectors, as used in some lighting devices in the prior art to provide an asymmetric light emission.
  • Each individual luminous means 2 may for example consist of one or more LEDs. Other bulbs are also suitable, provided they all point in the same direction and emit transversely to the longitudinal direction of the rod-shaped light source carrier device 1.

  • Fig. 1 and Fig. 2 has fourteen bulbs 2. In other embodiments, less than fourteen or more than fourteen bulbs 2 are mounted on the rod-shaped lamp carrier device 1.
  • Fig. 3 schematically shows an embodiment of a lighting device according to the invention 3. If one imagines this lighting device according to the invention 3 to a ceiling of a room, it shows Fig. 3 a plan view of the lighting device 3 according to the invention seen from the floor of the room.
  • This in Fig. 3 illustrated embodiment of the lighting device 3 according to the invention has five parallel to each other and parallel to the ceiling ceiling extending rod-shaped lighting means 1 with the associated bulbs 2, as in the FIGS. 1 and 2 shown and explained above, on.

Instead, are in the in the Fig. 4 illustrated embodiment of the lighting device 3 according to the invention, the rod-shaped light-emitting means 1 tilted with respect to the perpendicular vertical lines, so that all bulbs 2 point in this embodiment to the left.
  • the crucial difference of the invention over other known from the prior art lighting devices in which, for example, all lamps can point to the left, here is that the rod-shaped lamp support means 1 are not all tilted by the same angle relative to the perpendicular vertical. Instead, each of the five rod-shaped illuminant support means 1 in the embodiment of FIG Fig.

  • the exact shape of the asymmetrical light emission I1 of the illumination device 3 according to the invention is determined by the emission characteristic of the individual light sources 2 and by the tilt angle of the rod-shaped light source carrier devices 1.
