  • This additional lamp 105 is a lamp which is mounted on the lamppost 102 by means of an arm. This subsequent mounting an additional light is associated with a relatively high cost.
  • the present invention is based on the object to provide a novel and improved way to be able to achieve a complementary illumination of an adjacent area in street lamps of the type described above.
  • the solution according to the invention is based on the idea of using a luminaire which is of ring-shaped or cuff-shaped design such that it can be fastened to the outer circumference of, for example, the mast of a street lamp. Further, a plurality of point-shaped light sources are arranged on or in the lamp housing, which emit light in different directions.
  • a luminaire is proposed in particular for illuminating walkways, pedestrian crossings or squares, with an annular luminaire housing which is designed to be fastened to the outer circumference of a carrier element, in particular to a street lighting mast. wherein on or in the lamp housing a plurality of substantially point-shaped light sources are arranged, which emit light in different directions.
  • the solution according to the invention is thus again based on the idea of completing a conventional street lamp with an additional luminaire in order, for example, to be able to illuminate an area located next to the street.
  • a ring-like light housing By using a ring-like light housing, however, there is now the possibility of making the extra light very compact and also to simplify the installation on the existing light pole.
  • the light also has clear advantages seen from a lighting technology perspective, since the use of multiple individual light sources, the possibility to adapt the radiation characteristics of the lamp in an optimal manner to the particular situation.
  • asymmetrical light emission ranges can be created, for example, with which, for example, sidewalks can be optimally illuminated over a relatively long range.
  • the light sources of the luminaire according to the invention are preferably LEDs or light-emitting diodes, it being possible for the light sources each to be associated with optics in order to be able to set the light output to a desired range.

  • the emission angle of the light sources with respect to the horizontal can be substantially equal.
  • the emission angle for the light sources can also be designed differently in order to set the light emission range in the desired manner.
  • a lighting arrangement consisting of a floor lamp, in particular a street lamp, with a lamp post and attached to the lamp post additional lamp, the additional lamp is configured as described above. It is provided in particular that the additional lamp is arranged on the lamppost at a height of about 0.9 m to 1.2 m. As will be described later, in the illumination of the area to be illuminated, this leads to particularly positive characteristics with regard to the perceived brightness.
  • a luminaire is proposed by the inventive solution, with the optimally complementary, for example, to a street lamp an adjacent area - eg. A walkway or a pedestrian crossing - can be illuminated.
  • the luminaire according to the invention is characterized by particularly positive photometric properties.

  • the lamp 1 is hereby mounted on the outer circumference of the mast 102 and accordingly has a housing 2, which - as shown in Fig. 2 - ring-like or designed cuff-like.
  • the circular opening 3 in the center of the housing 2 has a cross section which corresponds approximately to the cross section of the lamp post 102.
  • the luminaire housing 2 can be subdivided into a plurality of segments, which are respectively applied to the outside of the mast 102, so that ultimately the annular structure results. It would also be conceivable, for example, to subdivide the housing into two half rings, which are connected to one another via a joint in such a way that they can be easily attached to the mast 102 in the unfolded state and then folded into a ring shape. Furthermore, it would of course also be conceivable to design the housing in such a way that the luminaire can be fastened to support elements with other cross-sections, for example square-shaped luminaire masts.
  • the light sources 10 are, in particular, punctiform light sources, for example LEDs, which can be arranged either in the housing 2 or on the outside thereof.
  • the LEDs are arranged within the housing 2, wherein the light output via provided on the housing 2 openings 11 takes place, in each of which transparent radiating elements are arranged.
  • these radiating elements can be designed as lenses in order to direct the light emitted by the point-shaped light sources into specific areas.
  • the use of other optics such as pot-like reflectors or the like. would be useful to affect the light output of the individual light sources 10 in the desired manner.
  • the light sources 10 are arranged substantially on one side of the housing 2 with respect to the central axis of the luminaire 1.
  • Such a configuration is particularly suitable for cases in which asymmetric light emission is desired. This can - as in Fig. 3 darg Pope - be used in particular to illuminate elongated areas, for example, a walkway.
  • FIG. 3 shows two street lights 100 arranged on the side of a road 110, via which the road 110 is to be illuminated in the first place.
  • a luminaire 1 according to the invention is further arranged in each case, which is intended to illuminate the located next to the road 110 area 111 of a walkway.
  • the light sources which are arranged only on one side of the housing 2 and whose horizontal radiation angles are suitably selected, radiating regions C are generated which have a significantly greater emission in a longitudinal direction along the road 110 than in the direction transverse thereto.
  • Such an asymmetrical light emission characteristic is particularly suitable for effectively illuminating sidewalks.
  • the horizontal radiation angle of the individual light sources of the luminaire 1 can be adjusted in particular such that the radiation regions C merge into each other almost seamlessly, so that ultimately a uniform illumination of the sidewalk 111 over the entire length is achieved.
  • This is u.a. achieved in that the outer light sources emit light under a - compared to the horizontal - flatter angle than the central light sources.
  • the light sources 10 are arranged exclusively or predominantly on one side of the housing 2 and furthermore their horizontal radiation angle is different, so that ultimately an asymmetrical emission characteristic is achieved.
  • the realization of a uniform over the entire circumference of the lamp 1 radiation would be conceivable, as shown schematically in Fig. 4.
  • the individual light sources 10 are arranged distributed uniformly over the entire circumference of the lamp housing 2, so that a nearly circular emission is achieved.
  • Such a radiation characteristic can, for example, be desired if the luminaire 1 according to the invention on the mast a street lamp is mounted, which serves, for example, for the illumination of places or the like ..
  • the assembly of the luminaire 1 according to the invention on the support element is preferably carried out at a height h of about 0.9 m to 1, 2 m. This results in a further positive effect, which is shown schematically in Fig. 5.
  • the relatively low mounting height of the lamp 1 has the consequence that the light emitted by the individual light sources at a relatively shallow angle ⁇ on the surface, for example, to be illuminated walkway.
  • the light in the alternative solutions according to FIGS. 6 and 7 would strike the surface as shown schematically at significantly larger angles ⁇ .
  • Use of the luminaire 1 according to the invention gives rise to the impression of a higher brightness or, compared to the known solutions of FIGS. 6 and 7, less light is required in order to achieve the same brightness impression in the observer 50.
  • a luminaire is created by the solution according to the invention, which has significant advantages in comparison with hitherto known luminaires with regard to their lighting properties and because of the diverse possibilities for designing the light emission area.
  • the lamp can be easily attached to existing street lights. Since the size and shape of the sleeve-like housing can be easily adapted, there are also no limitations with regard to the possible uses of the lamp.
