Definitions

  • the invention relates to a light distributor for a lighting device and a lighting device with at least one light distributor.
  • the lighting device may for example consist of a lamp, such as a pendant, recessed, floor or wall lamp, which has as light source at least one electric lamp, for example at least one tubular and / or U-shaped fluorescent lamp.
  • the lighting device may also be designed as a light band lighting device having a rail and at least one row along this successive lamps, which in turn consist of tubular and / or U-shaped fluorescent lamps, for example.
  • the lighting device is intended in particular for use in a room, such as a large office, in which at least one person works on a screen.
  • a known lighting devices have a light source with a fluorescent lamp and arranged under the light source light distributor with a distributor element, which consists of a flat piece of sheet metal with a number of light transmission holes.
  • the sheet metal piece is provided in some variants with downwardly projecting collars.
  • the light transmission holes are either completely or mostly cylindrical and, in the latter case, have a portion tapering downwardly from the top. The relationship between the lengths and the cross-sectional dimensions of the holes is indeed set so that the light directly radiated through the light transmission holes is at least equal to a predetermined masking angle with a horizontal plane.
  • the boundary surfaces of the light transmission holes are at least reasonably light-reflecting
  • light generated from the light source may, in a light-emitting device, be deflected once or more at the boundary surfaces of the light-transmitting holes even in "flat", ie, almost horizontal, directions through the holes of the manifold Elements are radiated into the space containing the lighting device and directly to a screen arranged in this room.
  • Such light can also be reflected from the screen into the eyes of a person working on it and blind them. If, therefore, the said boundary surfaces are reasonably light-reflecting, the known lighting devices can not really avoid glare.
  • the confinement surfaces of the light-transmitting holes completely absorbed the incident light, there would be little yield of the light generated by the light source.
  • the US Pat. No. 2,506,951 discloses various distribution elements for luminaires.
  • the distributor elements consist of plates bounded both above and below by a flat surface and provided with holes for the passage of light.
  • the holes extend from top to bottom and have a circular hole end at the top, a square-shaped hole end at the bottom and straight boundary surfaces in sections through the hole axes.
  • the embodiment shown in Fig. 3 is largely similar, but has holes whose boundary surfaces are bent concave in a section through the hole axes.
  • the distributor elements are made of metal, for example.
  • the holes are to be made for example by punching and embossing.
  • Other known light distributor have a serving as a distributor element lamellar grid with two mutually parallel edge strips or a four edge strips having frame and a number of the edge strips and / or possibly attached to each other slats.
  • the edge strips and slats consist of thin, light-reflecting sheet metal pieces.
  • the lamellae are usually a few centimeters apart.
  • the edge strips and fins are usually a few inches high.
  • Such light distributors therefore have the disadvantage that the louvre grids require a relatively large amount of, for example, at least or about 2 centimeters, which is often undesirable.
  • a large number of individual slats must be produced and, above all, fastened individually. The production and assembling a louver grid is therefore very expensive.
  • the invention is based on the object to provide a light distributor, which eliminates the disadvantages of the known light distributor.
  • the light distributor should make it possible to suppress the direct emission of light in undesired directions and still only take up little space, especially only a small height range.
  • the light distributor should also be economical to produce and allow a high light output.
  • the invention further relates to a lighting device having the features of claim 12, a use of the lighting device according to claim 16 and a method for producing a distributor element according to claim 19.

  • the light distributor 21 is generally in the form of a plane, horizontal, rectangular, namely rectangular plate, wherein the two longer edges of the light distributor are parallel to the tubular fluorescent lamps.
  • the light distributor closes the light source chamber at least for the most part from below.
  • the housing 5 includes two side reflectors 23 attached thereto, which extend along the tubular fluorescent lamps 19 and are arranged on opposite sides thereof.
  • the reflectors 23 are arranged in the vicinity of the lateral boundaries of the light source chamber and / or form these boundaries at least in part.
  • the side reflectors 23 extend downwardly from the upper edges of the housing to at least approximately the light distributor 21 so that the lower edges of the reflectors are, for example, near the longer side edges of the light distributor on the upper side thereof.
