Definitions

  • the invention relates to a luminaire with an elongated light source, at least one reflector curved transversely to the lamp axis and a cover made of transparent material.
  • Luminaires of this type are generally known, fluorescent lamps, which are accommodated in a housing, usually being used as lamps.
  • the lamp exit surface is usually covered by a trough-shaped or disc-shaped cover, which is made of diffusely transmitting material to reduce glare or is provided with prisms.
  • the invention has for its object to provide an elongated lamp that has minimal losses with low glare and is inexpensive, with additional new opportunities for lighting and aesthetic design of the lamp should be given.
  • the arrangement of the prism cover inside the luminaire, offset from the light exit surface of the luminaire, provides good design options for both glare-free lighting and aesthetic training.
  • the reflectors parallel to the lamp axis take over glare control and light control in the C0 and C180 levels.
  • the fact that the reflector surfaces lying below the prismatic lens according to the invention can no longer be impaired in their effect by subsequent prismatic elements, the possibilities of light control are improved. For example, winged light intensity distributions are now possible in these levels.
  • Glare control on the C90 / C270 level is achieved by the prisms. Since the prismatic cover can no longer be seen at flat angles due to the reset, the inherent luminance no longer plays a role and the luminaire appears dark under these angles if the reflector is designed appropriately.
  • the prism cover Since the prism cover has extremely low absorption losses and since the light rays do not pass through the prism cover at certain points and in certain directions, it also acts as a reflector, the losses of which are less than that of the normal vapor-coated or anodized reflectors, if the cover is designed in this way, that the rays reflected from it do not go back into the lamp. In this way, it is possible to produce a low-loss direct-indirect luminaire.
  • Glare can also be improved if the prisms of the prism cover are arranged transversely to the lamp axis and / or if the cover is colored.
  • the 1 has a housing 7 in which one or more elongate lamps 2, for example fluorescent lamps, are accommodated.
  • the inner wall of the housing 7 is provided with a reflector 3, which deflects the light beams emitted by the lamp 2 in such a way that they emerge from the light exit surface 4 of the lamp.
  • a prismatic cover 5, which is curved around the lamp 2, is provided inwards to the light exit surface 4. The curvature is preferably chosen such that the rays emerging from the lamp 2 are not reflected back to it and that the losses are kept low.
  • the rays emerging from the lamp 2 and passing through the prism cover 5 are partially deflected at the side reflectors 3 and only then emerge from the light exit area 4 out.
  • the prism cover 5 and the reflectors 3 Due to the arrangement of the prism cover 5 and the reflectors 3 with respect to one another, different light intensity distributions, particularly in the C0 / C180 plane, can be realized. In this plane, glare control and light control by the reflectors 3 take place parallel to the lamp axis. In the C90 / C270 plane, the glare is determined by the prisms 6 in the prism cover 5.
  • the prisms 6 are arranged in strips in a manner transverse to the lamp axis, as a result of which the light intensity distribution of the lamp transverse to the lamp axis is influenced as little as possible, but the beam angle of the lamp along the lamp axis is effectively limited.
  • the prism cover 5 is preferably made of a clearly transparent material, but it is also possible to color the cover in order to additionally achieve improved glare control by utilizing long beam paths in the material at flat angles.
  • covers can also be flat; the prisms can be designed differently.
  • Tube 10 and lamp 2 can form a unit.
  • a direct indirect light is shown in Fig. 3.
  • This lamp is open at the top or provided with openings or covered by a transparent cover.
  • the prism cover 5 acts partially as a reflector, since a reflection occurs at the points at which the light rays do not pass through the prisms. Since the prism cover 5 has practically no absorption losses, low-loss direct-indirect lighting is made possible by this arrangement.
  • the prism cover 5 must be curved in such a way that the rays reflected by it do not go back into the lamp.
