Definitions

  • the invention relates to a wide-beam indirect light according to the preamble of claim 1.
  • the invention is a luminaire of the aforementioned Art be improved so that on the one hand too strong Luminance on the ceiling immediately above the luminaire on the other hand, the greater part of the radiated light sideways and obliquely upward is radiated to a good and uniform illumination to achieve the space.
  • additional reflector becomes a part of the inside directed light emission of the fluorescent tubes upwards deflected, resulting in a more uniform illumination of the located directly above the luminaire housing Ceiling area is reached.
  • Luminaire housing 14 Since the distance A from the ceiling 10 to the lower edge 12 of Luminaire housing 14 according to Figure 1 from the above The reasons should be as small as possible, this is proportionate flat luminaire housing 14 by means of a short lamp shaft 16 and an approximately conical ceiling rosette 18 in short distance from the ceiling 10 attached.
  • the lower part 20 the lamp housing 14 is curved slightly convex downward and is made of opaque material, however e.g. in the form of a perforated plate or by means of other breakthroughs Optionally let more or less light down can.
  • each in upwardly bent portions 22nd At the upper ends of the obliquely upwards and inwards Sections 22 may be a well-translucent top Connect 24 of the light housing 14 in an advantageous manner.
  • the luminaire housing 14 is symmetrical to one in the direction the longitudinal extension of the lamp housing 14 extending vertical center plane 26 is formed. At equal intervals from the median plane 26 and at the same height above the Lower part 20, i. approximately at the height of the bent sections 22 of the lamp housing 14, one is parallel to the Midplane 26 extending arc tube 28 is arranged. Above each arc tube is each a substantially strip-shaped, flat down concave curved reflector 30 attached, the lower edge at a location 32 at the top Half of the luminous tube circumference approximately rests or in low Distance from the same is arranged. In the illustrated Embodiment is this point 32 from the apex line 34th each arc tube 28 shifted to the center plane 26 out.
  • each reflector 30 On his remote from the respective associated arc tube 28 At the end, each reflector 30 has a stiffener in it Serving in the longitudinal direction, pointing obliquely outwards and downwards Bend 36 on.
  • the relatively flat reflectors 30 are upwardly and inwardly, i. towards the median plane 26, slightly convex and slightly concave curved outwards and downwards.
  • each inclined obliquely upwards and inwards level reflector surface 40 forms, with the respective opposite reflector 30 an upwardly flared includes acute angle. This angle goes here from the mean inclination of the vertical section of the reflector 30 regardless of its curvature. Every level Reflector surface 40 has at its lower edge to the Center plane 26 pointing towards bending 42.
  • Each reflector 30 serves essentially to that of the Incandescent tube 28 outgoing light for the most part in one indicated by dashed lines, obliquely laterally to direct the above-pointing angle range B.
  • the lower limit 44 of the angular range B is thereby through the upper edge of the bent portion 22 determines while the upper limit 46 is determined by the outer edge of the bend 36.
  • the outer boundary 48 of the angular range C is determined by the convexly curved inner side of the reflector 30, while the outer limit 50 is determined by the reflection surface 40 of the reflector 38.
  • the remaining light of the fluorescent tubes 28 goes down the inner surface of the lower part 20 of the lamp housing 14. Es is reflected from here also partly upwards and on the other hand, to a small extent, down, e.g. through holes in a perforated plate or the like, from.
  • the bends 42 of the central auxiliary reflector 38 are used for more uniform lightening of the lower part 20 to one to achieve uniform brightness effect, if one uses the Luminaire viewed from below.
  • the lamp shown in Figure 1 is in its short Suspension on the ceiling 10 in approximate relation to Room height shown, while in Figure 3 in their arrangement on a standing on the floor 13 high stand 17 with Stand 15 is shown.
