Definitions

  • the present invention relates to a luminaire with a rod-shaped, in particular horizontally arranged light source with concave-curved side reflectors extending from below to above it on both longitudinal sides of the light source, between which a light outlet opening is formed in the housing below the light source, a dimming body being arranged below the light source is.
  • the anti-glare body consists of a strip-shaped flat material which has a large number of light exit openings in its surface.
  • This dimming body is intended in particular to ensure dimming in the longitudinal direction of light emitted by the light source.
  • the light output of the luminaire is adversely affected by the screen-like design of the dimming body, and reflections in the longitudinal direction also continue to occur.
  • the present invention has for its object, starting from a lamp of the type described above, to improve them in such a way that both an optimal suppression of the emerging light beams in the longitudinal direction and in the transverse direction is achieved, and the luminous efficacy of the luminaire is only slightly influenced. At the same time, cost-effective production should be guaranteed.
  • the anti-glare body consists of highly translucent material and at least partially encompasses the light source circumferentially, and consists of a sheet-like or thin-walled material, and has a prism structure made of prisms running parallel to the longitudinal axis of the housing on its surface facing the light exit opening.
  • the peripheral angle of the anti-glare body is such that no light can enter the side reflectors directly from the light source.
  • the light deflection achieved by the masking body according to the invention causes both a masking in the transverse direction and a masking in the longitudinal direction of the light beams emerging from the light source in such a way that there is no glare by reflecting the light source in the side reflectors or any front reflectors that may be present.
  • a luminaire according to the invention has a rod-shaped, horizontally arranged light source 1 (fluorescent tube).
  • Concave, in particular parabolic, curved side reflectors 2, 3, which can be formed in two parts or in one piece, extend from above to below on both longitudinal sides of the light source 1.
  • the side reflectors 2, 3 can be connected at their upper edges by a roof reflector 4. It is also within the scope of the invention if there is no roof reflector 4, so that the lamp according to the invention is open at the top.
  • the side reflectors 2, 3 can be formed symmetrically with respect to the longitudinal vertical center plane 5, but an asymmetrical configuration of the side reflectors with respect to the center plane 5 is also possible.
  • the lamp according to the invention also has two end reflectors 7, 8 which connect the side reflectors 2, 3 on the end face.
  • the light source 1 is held in the usual manner in sockets 9, 9a.
  • a shielding body 10 is arranged below the light source 1.
  • This anti-dazzle device 10 consists according to the invention of highly permeable material and can be designed as a film or as a thin-walled, dimensionally stable body, the shielding body 10 having a prism structure on its surface facing the outlet opening made of prisms 11 running parallel to the longitudinal axis of the housing, see FIG. 2. These prisms 11 are shown in FIG illustrated embodiment executed as isosceles triangles in cross section with a tip angle of 90 °.
  • the anti-glare body 10 is made as a so-called toothed foil, in particular made of polyacrylic glass, and is arranged inside a tube 12 made of a highly translucent material, for example polyacrylic glass, which surrounds the light source 1, on the inside of the tube 12.
  • the anti-glare body 10 is also tubular. It is essential according to the invention that the circumferential angle of the shielding body 10 with which it surrounds the light source, namely on the side of the light source facing the outlet opening, is dimensioned such that no light can enter the side reflectors 2, 3 directly from the light source.
  • d 1 means the diameter of the anti-glare body 10 in the base of the prisms 11 and d 2 the average diameter in the area of the prisms 11.
  • the tube itself can also have the prism structure according to the invention directly on its outer surface. It is also possible to arrange a film-like shielding body around the light source 1, which is fastened in the luminaire by corresponding holders. In the case of a closed, tubular shielding body or an arrangement of a foil-like shielding body, for example Within a tube, as shown in FIG. 1, it is expedient if there are ventilation openings on the side of the tube opposite the outlet opening 6 in order to enable better heat dissipation from the tube.
  • the solution according to the invention is based on the fact that a pre-calculated combination of refraction and total reflection ensures that the light is deflected from certain angular ranges in order to avoid the risk of glare.
  • the optical structure according to the invention consists of clear material, i.e. it is a material that allows light to pass through, so that the luminaire according to the invention is highly efficient.
