Definitions

  • the invention relates to a reflector lamp, in particular a ceiling reflector lamp.
  • Ceiling lights are said to be in the space below them illuminate in such a way that there is no glare arises. This means that the light emitting Lamp must be shielded so that it can be viewed by the viewer cannot be viewed directly. Thereby a considerable part of the luminous flux as directed light be emitted in such a way that glare on screens and the like can be avoided.
  • a luminaire that meets these requirements is off DE-GM 85 19 706 known. To do this is under the lamp arranged as a primary reflector, that partially surrounds the lamp. From the primary reflector is the light emitted by the lamp in the direction of Reflected ceiling. On the ceiling is above the lamp a secondary reflector arranged by the lamp and light coming from the primary reflector into the room reflected. The primary reflector located under the lamp causes however in the light exit area Reflector lamp a shade, being darker The bar appears. In the light exit area of the lamp there are therefore uncomfortable differences in luminance. Furthermore, the light in such a reflector lamp reflected one or more times, with the result that such pure secondary light emitters have poor efficiency.
  • DE-GM 92 13 886 is a lamp in the form of a secondary lamp known in which the primary reflector consists of perforated sheet. Enters through the holes Part of the light emitted by the lamp directly in the room so that no disturbing shadows from the Primary reflector are caused. A glare through the light rays emerging through the perforated plate to avoid, the primary reflector is on ner inside or outside with a translucent, provided with opal or milky white foil. As Diffuser-looking opal film sprinkles this through the Holes in the perforated plate prevent light from escaping hence the glare. However, opal material shows in general high transmission losses, which in turn deteriorate the efficiency of the reflector lamp.
  • the Primary reflector for example, a rod-shaped fluorescent lamp to cover completely, it must be stable be trained. Therefore, it is necessary to be relative to use thick perforated sheet. So are for the shaping of the primary reflector complex and expensive tools required.
  • the object of the invention is to provide a diffuser for To create reflector lamp that is simple and inexpensive is producible and in which also Primary reflector can be produced cost-effectively without additional ones Components are protected.
  • the reflector lamp according to the invention has a perforated Primary reflector on by a diffuser surrounded and towards an opposite secondary reflector is open.
  • the diffuser a dimensionally stable molded body that the primary reflector wearing.
  • the diffuser is made of polymethyl methacrylate with embedded methacrylates with slightly different Refractive index produced. This material has that Advantage that there are almost no transmission losses and the diffuser therefore have a material thickness can, which enables high dimensional stability. This is the efficiency of the reflector lamp according to the invention compared to known reflector lights significantly improved.
  • the primary reflector can have low stability. So he can Primary reflector made from very thin perforated sheet or from one Be made of metal foil. The production of the The primary reflector is thus considerably simplified. For Shaping the primary reflector can therefore be simpler Tools are used. Especially punching out the perforation is made of a very thin sheet considerably easier and cheaper.
  • the diffuser serves as protection for the primary reflector from pollution and damage.
  • the diffuser can also because of its dimensionally stable design and its massive smooth outer wall can be cleaned well.
  • the diffuser designed as a molded body can be due to of its material by injection molding or extrusion getting produced.
  • the manufacture of the as load-bearing Part serve diffuser is thus considerably easier than a complex bending of a primary reflector is sufficient thick perforated sheet. Furthermore, they are complicated Molds made easier by injection molding.
  • the shape of the primary reflector preferably corresponds that of the diffuser in such a way that the primary reflector is in full contact with the diffuser.
  • a firm connection between the primary reflector and the diffuser not mandatory.
  • the diffuser be bowl-shaped or hemispherical and a the same shape primary reflector made of thin Sheet metal can be inserted into the diffuser.
  • the primary reflector is made of a curved elastic resilient sheet made of tension inserted into the diffuser and against the inside of the diffuser. So the location of the primary reflector clearly defined in the diffuser without the Having to firmly connect the primary reflector to the diffuser. Therefore, the primary reflector can be used, for example Simply clean the lamp separated from the diffuser will.
  • the reflector lamp shown in Fig. 1 has elongated lamp housing 10, which is vertical extends to the drawing plane.
  • the lamp housing 10 is designed such that it as a recessed light or as a surface-mounted lamp or as a pendant lamp a ceiling can be attached.
  • the lamp housing 10 contains a longitudinal secondary reflector 12 which is arched upwards and preferably a diffuse Has inside.
  • For attaching the secondary reflector 12 in the lamp housing 10 has the secondary reflector 12 along its longitudinal edges lugs 13 on, which are connected to approaches 14 of the bracket.
  • the luminaire housing has outside the secondary reflector 12 10 at both ends a front housing wall 15, with a suspension 20 each an intermediate part 21 is connected.
  • the lighting unit 11 is fastened with retaining rings 22.
  • the lighting unit 11 has one in the direction of the secondary reflector 12 open diffuser 23 and a primary reflector 24 on, which is perpendicular to the plane of the drawing extend and a rod-shaped fluorescent lamp 25 partially enclose the lighting unit 11.
  • the diffuser 23 is at both ends with an end wall 26 closed.
  • the end walls 26 contain the lamp holders for the lamp 25.
  • the lamp 25 is eccentric in the vertical direction arranged the primary reflector 24, the location of the Lamp 25 and others on the opening width of the primary reflector 24, and the shape of the two reflectors 24, 12 is dependent. Furthermore, the arrangement of the lamp 25 of the distance of the light unit 11 from the light housing 10 dependent. Corresponds in the illustrated embodiment this distance is about the depth of the secondary reflector 12th
  • the diffuser designed as a dimensionally stable molded body 23 is a partial pipe that is extends more than 180 ° (Fig. 2).
  • the primary reflector 24 which has slots 27, inserted in the longitudinal direction.
  • the outer dimensions of the primary reflector 24 in a relaxed state slightly larger than the inside dimensions of the Diffuser 23, so that the primary reflector 24 under tension is held in the diffuser 23.
  • the diffuser is designed as a partial tube that extends by more than 180 ° extends, is the same shape primary reflector 24 due to the bias in the diffuser 23 held so that sticking or solid Connect to the diffuser 23 is not required.
  • the primary reflector 24 is due to the bias over the entire surface of the diffuser 23.
  • FIG. 1 Light emitted by the lamp 25 is through in FIG. 1 the beam paths 30-35 indicated.
  • the slots 27 are made of a special material of the primary reflector 24 optically expanded and generate uniform luminance on the diffuser profile.
  • the light beam 32 emanating from the lamp 11 meets the secondary reflector 12 directly. Since the secondary reflector 12 has a diffuse surface, beam 32 becomes on the surface of the secondary reflector 12 reflected as a beam 33.
  • Beam 34 strikes the shiny inside of the primary reflector 24 and is reflected by it in a directed manner and then hits the secondary reflector 12, on which it is reflected as a beam 35. Of the The space underneath the reflector lamp is thus evenly illuminated.
