Definitions

  • the present invention relates to a lamp with a bowl-shaped reflector for directional light emission via a light exit surface of the reflector with a preferably defined tear-off edge of the light output.
  • Such lights have been operated using high-pressure lamps, which allow a defined light distribution with sharp spoiler edge.
  • Such lights are used for example as a ceiling washer in the form of pendant lights. They provide a particularly high amount of light. For example, light intensities of up to 20,000 lumens can be achieved. Due to legal requirements, however, such high-pressure lamps are only available until the end of 2016.
  • the present invention now aims to provide a comparable luminaire which dispenses with the use of high-pressure lamps.
  • the present invention relates to a luminaire with a dish-shaped reflector having a circumferential reflector wall extending away from a bottom region of the reflector, which delimits a light exit surface on its side opposite the bottom region.
  • the luminaire according to the invention has a hollow body extending longitudinally from the bottom region into the reflector and towards the light exit surface and open on both sides with respect to its longitudinal axis. Distributed over the circumference of the hollow body, illuminants are provided in such a way that they are in thermal contact with the hollow body and emit light at least in part radially - that is, laterally - onto the reflector wall.
  • the lamp has a quasi tubular hollow body, with which the lamps are in direct thermal contact, so that the heat generated during operation of the lamps can be discharged directly to the hollow body. Due to its hollow design, it provides a large surface area for dissipating heat generated during operation. Due to the open on both sides of the form of the thermally coupled with the bulbs hollow body convection and consequently a so-called chimney effect is achieved, which automatically leads to increased heat dissipation by constant air flow.
  • the reflector wall preferably expands away from the bottom region.
  • a substantially parabolic cross-section is provided here.
  • Such a shaped, shell-shaped reflector offers a good possibility for the corresponding, directed reflection of the light emitted by the bulbs on the reflector wall light in the direction of the light exit surface.
  • the reflector wall is designed in such a way to direct the light of the luminous means to the defined light emission in the direction of or at least partially onto the light exit surface.
  • the light emitted by the bulbs light is thus guided defined and directed to the light emitting surface, so that a desired radiation characteristics can be achieved.
  • the hollow body may be designed to be reflective on its side facing the reflector wall. In particular, this applies at least in the region between the lighting means and the light exit surface, that is, as viewed from the light sources, directed towards the light exit surface.
  • a part of the light deflected by the reflector wall is preferably directed selectively targeted to the reflective surface of the hollow body, so as to stand by the defined light output via the light exit surface.
  • the hollow body is seen in the longitudinal direction of the reflector preferably arranged centrally to or in the reflector. In this way, a symmetrical design of the lamp can be achieved, which in addition to aesthetic considerations for a harmonious light output is beneficial.

  • the hollow body is round, oval or polygonal in cross-section.
  • a regular polygonal cross-section is advantageous in order to generate as uniform a light as possible in the circumferential direction.
  • the reflector and the hollow body are preferably designed in such a way as to emit the light of the luminous means with a defined light emission angle, preferably with a defined spoiler edge, via the light emission surface.

  • the light emission angle is preferably measured with respect to the main emission direction of the luminaire, preferably in or parallel to the longitudinal axis of the hollow body. In the latter case, a periodically or otherwise uniform change of the light emission angle is conceivable. Also, a circumferentially asymmetrical light output is conceivable.
  • the lighting means are provided (directly) on the hollow body.
  • the bulbs are in the range of Floor area of the reflector, so as close to the foot of the reflector, provided in order to provide the entire reflector wall surface for defined light output via the light exit surface can.

  • a different arrangement or orientation of the hollow body 6 with respect to the reflector 2 is conceivable.
  • the hollow body 6 may preferably extend at least to the light exit surface 4.

If the hollow body 6 is not or not partially provided with a reflective surface, it can be used, for example, for the absorption of the light impinging on it as well for defined light output.
  • the hollow body 6 may be formed round in cross-section.
  • the hollow body 6 may also be formed oval or polygonal. In the latter case, one is especially regular polygonal training preferred to achieve the most harmonious and uniform light output.
  • the hollow body 6 can have seen in the longitudinal direction or in the direction of its longitudinal axis L different diameters. This is for example in the side view in FIG. 2 clearly visible.
  • the light sources 7 may preferably be provided on a region 61 of smaller diameter d, while, for example, a region 62 provided between light sources 7 and light exit region 4, which in particular forms the reflective region of the hollow body 6, will be an area 62 of larger diameter.
  • a preferably light emission and light guidance can be achieved.
  • the reflector wall 5 is preferably designed in such a way as to direct the light of the luminous means 7 toward the defined light emission of the luminaire 1 in the direction of or at least partially onto the light exit surface 4.
