Definitions

  • the present invention relates to a luminaire with a designed as a high-pressure discharge lamp bulbs, which is surrounded by a reflector, and with at least one additional light source, which emits monochromatic light in the reflector.
  • lighting systems are used in which modern, effective bulbs with a high light output such as metal halide lamps in the light colors warm white (3000 K), neutral white (about 4000 K) and daylight (about 6500 K) used become.
  • the aim is always to illuminate the usable areas evenly and with a high general color rendering index, which reflects all body colors as evenly as possible, with little effort.
  • the above-mentioned bulbs emit a radiation in whose light spectrum all light color components are present.
  • the narrow band filters used are commonly made as interference filters, and their function requires a variety of interference layers.
  • the lighting means and the filter element must be aligned at a certain angle to each other, whereby the flexibility in terms of the structure of such a equipped lighting system is limited.
  • a generic lighting system in which in addition to a primary light source additionally monochromatic emitting secondary light sources are provided.
  • the intensity of the secondary light sources can be adjusted continuously to change the color location and in particular the color temperature or light color.
  • the object of the present invention is to provide a luminaire of the type mentioned, which achieves optimum utilization of the monochromatic radiation emitted by the additional light source.
  • the additional light source is positioned so that it emits the monochromatic light in the direction of the high-pressure discharge lamp, and that an optical system is provided which focuses the emitted light from the additional light source such that it completely hits the burner of the high-pressure discharge lamp.
  • the luminaire in addition to the luminous means illuminating the useful surface, which is a radiation having a high general color rendering index emitted and in whose light spectrum all light color components are present, at least one further monochrome, so in a very narrow spectral range emitting additional light source provided.
  • the color saturation of the corresponding body color which is also present within the light spectrum emitted by the light source, is amplified, so that it is emphasized.
  • a body color which may not be present within the light spectrum of the luminous means, may also be added to the light spectrum of the luminous means.
  • the light emitted by the additional light source is aligned and focused by the optical system in such a way that it completely strikes the burner of the high-pressure discharge lamp.
  • the burners of high-pressure discharge lamps are made of a material such as alumina ceramics, which strongly scatters the monochromatic light impinging on them so that it uniformly mixes with the light emitted from the high-pressure discharge lamp. In this way, a high color penetration is achieved without significantly increasing the overall performance of the luminaire by the admixed monochromatic light. Moreover, it is prevented by the inventive focusing that the monochrome light blasted past the high-pressure discharge lamp against the reflector what would lead to the formation of colored dots on a usable area to be illuminated.
  • the optical system which may comprise lenses and / or reflectors, focuses the light onto the center of the burner of the high-pressure discharge lamp, since in this way a very uniform scattering on the burner of the high-pressure discharge lamp is reached.
  • several same color emitting light sources can be provided on opposite sides of the high-pressure discharge lamp and in particular arranged symmetrically, so that the burner of the high-pressure discharge lamp uniformly irradiated with the monochrome light and the result is a uniform illumination of the reflector is achieved.
  • the monochrome light sources dimmable it is possible to design the monochrome light sources dimmable.
  • the dimmer on the one hand, the brightness and on the other hand, the saturation of the light emitted by the lamp with a certain color can be adjusted.
  • the illuminant of a reflector in particular a Batwing Lichtver-distribution generating reflector to surround.
  • the reflection of the box reflector achieves a high degree of lighting efficiency and produces a homogeneous propagation of the radiation emitted by the light source.
  • a particularly effective single-color emitting light source with high efficiency and low maintenance costs is a light-emitting diode (LED).
  • LED light-emitting diode
  • a light source in the form of a metal halide lamp or a high-pressure sodium vapor discharge lamp with improved color rendering.
  • These lamp types represent modern, effective light sources with a high light output.
  • a lamp 1 according to the invention is shown schematically, which can be mounted, for example, on a ceiling.
  • the luminaire 1 has a luminous means 2 which emits radiation with a high general color rendering index, in the light spectrum of which all light color fractions are approximately uniformly present.
  • the luminous means 2 here is a high-pressure discharge lamp with improved color rendering, such as, for example, a high-pressure sodium discharge lamp or a metal halide vapor lamp.
  • the luminous means 2 is surrounded by a reflector 3 which generates a batwing light distribution and has a light exit opening 4 on its underside.
  • the reflector 3 is of conventional design and is formed by side reflectors 5 and a cover element 6.
  • the cover element 6 is designed as a cold light mirror, which reduces the heat radiation.
  • the lenses 8 are designed and positioned such that they concentrate the light emitted by the light emitting diodes 7 and direct them to the high-pressure discharge lamp 2 such that the entire monochromatic light emitted by the light emitting diodes 7 impinges on the burner 2a of the high-pressure discharge lamp 2.
  • the lenses 8 in the present case focus the light emitted by the light emitting diodes 7 onto the central axis M of the high-pressure discharge lamp 2.
  • a total of four light-emitting diodes 7 are arranged symmetrically on both sides of the high-pressure discharge lamp 2 to the center plane of the lamp 1, so that the high-pressure discharge lamp 2 is uniformly irradiated with the monochrome light. Furthermore, a light-emitting diode 7 is provided on the cold-light mirror 6, which emits monochromatic light vertically downwards.
  • the burner 2a of the high-pressure discharge lamp 2 consists of an alumina ceramic, ie a material, which strongly scatters the monochromatic light impinging on it from outside so as to uniformly mix with the light radiated from the high-pressure discharge lamp 2. In this way, a high color penetration is achieved, with the result that a homogeneous radiation mixture leaves the reflector 3 at the lower-side light exit opening 4 and causes a saturation of the desired body colors on a usable area to be illuminated.
  • a shield 9 is provided below the high-pressure discharge lamp 2, which is intended to reduce direct light emission to the region of the area to be illuminated located immediately below the high-pressure discharge lamp 2, in order to achieve high light concentrations, which can lead to goods damage avoid.
  • the shield 9 can have passage openings (not shown) for a residual light passage and has on its side facing the high-pressure discharge lamp 2 a reflecting surface which can also be selectively reflective in order to filter out certain color components.
