Definitions

  • the invention relates to a light reflector, in particular a light reflector for lighting and lighting equipment.
  • Light reflectors with a mostly cylindrical or rotationally symmetrical, concave body are known for lighting purposes, for example as sh Georgiser or as a parabolic mirror.
  • Reflectors are known whose reflection surface has a faceting. For example, shows the US 6,206,549 a light reflector with an at least partially faceted surface.
  • reflectors with differently shaped facet circumferences are known which are provided with a coloring layer applied by sputtering.
  • the application of this color layer by sputtering is intended to increase its scratch resistance and to improve its appearance vis-à-vis coating layers applied on the inside.
  • the scope of these facets is illustrated graphically, the curvature of the respective facets is not described.
  • the document GB 2 065 287 which is considered to be the closest prior art, discloses a reflector with different facets for producing uniform light, wherein in one area at the light exit the facets have spherical shapes, in another area near the light source the facets have triangular cross-sectional shapes.
  • the sharpness of the contour of the light field is an important criterion for its use.
  • the sharpness of the perceivable contour at the boundary of a light beam critical angle is, for example, in DIN 5040-4 as a function of the illuminance gradient S ( ⁇ ) defined as values of K3 to K5, where ⁇ is the angle of the exiting light relative to the axis of symmetry of the reflector, see for example DIN 5040-4, 1999-04 paragraph 5.4.
  • Reflectors with a contour sharpness K1, corresponding to S ( ⁇ )> 4 have a sharply limited beam without any stray light, whereas reflectors with a contour sharpness K5, corresponding to S ( ⁇ ) ⁇ 0.5, show a wide beam bundle with no apparent contour.
  • the inventors have set themselves the task of creating a reflector and thus provided lighting equipment in which the sharpness of the contour of the light field values of K3 to K5 may have and yet the shape of the reflection surface as simple as possible to calculate and manufacturing technology, especially in the hot forming , good to master.
  • a reflector shape To simplify the calculation of a reflector shape are facet basic shapes, which are, for example, spherical or cylindrical.
  • cylindrical facets are used, ie facets which essentially have the shape of a circular cylindrical section, which is generally tangential to the surface of the reflector and for better demolding with a substantially in the direction of Is arranged symmetry axis of the reflector extending cylinder axis.
  • spherical facets have the advantage that the light field of a lamp equipped with such a reflector runs out smoothly.
  • a disadvantage is the relatively low illuminance of a lamp or lighting device equipped with such a reflector, which makes it inappropriate for many applications, for example in film production, on stage and / or in the photo studio.
  • reflectors which have only spherical facets, especially as glass reflectors only very expensive to produce.
  • cylindrical facets have the advantage that a reflector which has only cylindrical facets with a cylinder axis substantially in the longitudinal direction of the reflector, while in its hot forming is generally well demoldable and also has a high illuminance;
  • the light field of a luminaire provided with such a reflector generally runs so hard in the edge region that tracking lights K1 or K2 and correspondingly high directivity can be produced here, but also this light field is suitable for many applications, for example in film production , on the stage and / or in the photo studio not suitable.
  • a light reflector is provided with a hollow body having an opening. It is in the invention to a hollow reflector, which has a focal or center region in which a light source can be arranged.
  • a center region is understood as meaning an area which is located in the vicinity of or in the optical axis of the reflector and may be displaced axially relative to the focal point of the reflector.
  • a light source such as an incandescent lamp, a high-pressure discharge lamp or even an LED or a plurality of LEDs can be arranged in the focal or center region.
  • the invention relates to a type of reflector whose reflection surface has faceting at least in sections.
  • the facets have a ratio of length to width at least partially in a first light-emitting means region, which is greater than the ratio of length to width in a second light-distant region. According to the invention, therefore, substantially elongate facets are provided in the region which is located close to the luminous means, which preferably extend radially in the direction of the midpoint region.
  • the length / width ratio of the facets is preferably determined based on the outline or the peripheral shape of the facets.
  • the light reflector is characterized in that the first area near the illuminator between 5 and 70%, preferably between 10 and 50%, particularly preferably between 20 and 35% of the reflection surface occupies.
  • a second region which is located farther away from the light source, has a faceting which has rather compactly designed facets, in particular approximately spherical or square facets.
  • the invention also includes reflectors which have, in addition to a first light-near and a second light-distant region, further regions.
  • the inventors have found that with such a type of reflector, the advantages of a spherical-faceted light reflector and the advantages of a light-reflecting reflector with cylindrical facets can be combined.
  • the rear region of the luminaire which is more distant from the luminous means, with more compact facets, for example spherical facets, it is achieved that the light field of a luminaire, which is equipped with a reflector according to the invention, runs out smoothly.
  • the front area near the illuminant, with the oblong facets, for example cylindrical facets ensures that a luminaire with a reflector according to the invention has a high illuminance.
  • a reflector can be provided with a soft light field that loses only about 5% light intensity compared to a reflector, which has only cylindrical facets.
  • known reflectors with spherical facets usually result in 30 to 40% low light intensity as reflectors designed with cylindrical facets.
  • the hollow body which determines the shape of the reflector, is a substantially cylindrical or rotationally symmetrical body, in particular a body having a substantially concave shape. It come here for the initially unfaceted basic shape of the reflector all reflector types into consideration, such as spherical, parabolic or ellipsoidal reflector types. The design depends mainly on the particular application.
  • the facets are at least partially convex and / or concave.
  • spherical and circular-cylindrical-segment-shaped facets are included, in which the surface of the spherical or circular-cylindrical shape protrudes out of the body of the light reflector as well as protrudes into the body of the light reflector.
  • the boundary is between a first region near the light and a second off-center region along an imaginary line of intersection of the hollow body to a plane perpendicular to the axis of symmetry or axis of rotation of the hollow body.
  • the light reflector is thus subdivided into a lower section which surrounds the light source or is provided for holding the light source and an upper section which has a compact faceting for scattering the light.
