Definitions

  • the invention relates to an electric lamp with a lamp housing, which has a bottom, side walls and a light exit opening, which is covered by a translucent cover, preferably a clear cover, wherein in the luminaire housing at least one electric light source and at least one reflector is arranged, by means of which be aligned radiating outgoing from the light source rays through the outlet opening.
  • Such lights are known in the art. Such lights are used for example as floor lights, the housing is installed flush and the preferably transparent cover is also inserted flush, with such lights are also traversed with vehicles.
  • the invention is based on the object to provide an electric lamp generic type, which is particularly suitable as a floor light for use close to the building, with unwanted light emissions are avoided and a balanced outdoor lighting in particular of building facades or the like is possible.
  • the reflector surface is formed as an asymmetric trough, so that the light rays exit asymmetrically from the light exit opening, and that on the side facing away from the reflector surface of the light source, two further reflector elements are arranged , which are spaced apart and extend parallel to the longitudinal axis of the trough, these reflector elements respectively a concave base facing the light source and reflecting a portion of the rays emanating from the light source towards the asymmetric well, having concave inner side surfaces facing each other and forming a parabolic sub-reflector by which the rays of the light source approximate rectified are bundled to the outgoing light rays from the asymmetric pan, and have concave outer side surfaces, by means of which a part of the beams reflected from the asymmetric trough a scattered light are generating, which forms a located on both sides of the main radiation area of the reflector pan scattered beam.
  • Such an electric light can be arranged, for example, as a floor light for close-to-building use very close to a building.
  • the appropriate training a narrow beam asymmetric soft and soft illumination of building facades is possible.
  • the outdoor lighting can take over the task, the appropriate building architecture and special To visually communicate and highlight elements of the building structure. This illumination of the building facades and the like is done without disturbing stray light for the residents and users of the building. Due to the arrangement close to the facade and the asymmetrical radiation characteristic directed towards the building, unwanted light emissions are avoided.
  • a grazing light component is also achieved, whereby a certain shading and recognizability of structures is effected.
  • such a luminaire achieves a very good lighting effect with high-contrast illumination of a building facade, so that building structures can be highlighted in a targeted manner.
  • the building-related installation made possible by the appropriate training, makes it possible to install such luminaires on the building's own property, ie not having to use neighboring properties or neighboring areas. The freedom of movement of residents and passers-by in public areas is hardly affected.
  • Constructions, such as masts or the like in the field are not required.
  • the light source is a T5 fluorescent lamp whose longitudinal axis is directed parallel to the longitudinal axis of the trough.
  • the reflectors or reflector elements are adjustable by a small angular degree, preferably by about up to 5 °.
  • the single drawing figure shows an electric lamp according to the invention seen in cross-section.
  • the luminaire has a luminaire housing 1, which may for example have a cuboid shape.
  • the housing has a light exit opening 2 arranged at the top in the drawing, which is covered by a light-permeable cover, for example by a transparent, break-proof glass.
  • a reflector 3 is arranged close to the ground, whose reflector surface is formed as an asymmetric trough, so that the rays emanating from a light source 4 are asymmetrically reflected approximately in the direction of the arrow 5.
  • two further reflector elements 6, 7 are arranged, which are held at a distance from each other and extend parallel to the longitudinal axis of the trough-like reflector 3.
  • These reflector elements 6, 7 each have a concave base 8, 9, which faces the light source 4 and a part of the emanating from the light source 4 rays in the direction Reflect on the reflector 3. Furthermore, these reflector elements 6, 7 concave inner side surfaces 10, 11 which face each other and form a parabol-like partial reflector, by means of which the outgoing from the light source 4 beams approximately rectified to the outgoing of the asymmetric tub (reflector 3) light rays are.
  • the reflectors 6, 7 have concave outer side surfaces 12, 13, by means of which a part of the rays reflected by the asymmetrical trough (reflector 3) are directed to produce a scattered light, which is located on either side of the main radiation area (in direction 5) of the reflector trough forms (the reflector 3) located scattered beam.
  • the light source 4 is preferably a T5 fluorescent lamp whose longitudinal axis is directed parallel to the longitudinal axis of the reflector 3.
  • the reflectors or at least the reflector elements 6, 7 are adjustable by a small angular degree, preferably by about 5 °, so that after installation of the lamp, preferably the bottom side is provided, an adjustment is possible.
  • an electric lamp on the one hand, it is possible to provide an invisible and non-disruptive arrangement within the floor in front of a building, with the appropriate orientation of the light beams extremely effective facade lighting is achieved, which is neither disturbing to the people within the building nor for the residents or the like produce disturbing light emissions.
