Definitions

  • the invention relates to colored lights, for. B. Illuminated advertising, street lighting, signal lights, decorations, indoor and outdoor lighting.
  • Colored luminaires have so far been realized using gas discharge tubes with different fillings and phosphors or by coloring the light source itself or the luminaire housing like a color filter and are therefore only permeable to part of the white spectrum.
  • the invention has for its object to realize color with the simplest possible 'means lights having over previously customary a higher efficiency for the generation of colored light and / or colored light with relatively high intensity. can radiate over any shaped surface (e.g. letters).
  • the primary focus is on organic fluorescent dyes in solid organic solution (e.g. of polymethyl methacrylate).
  • the fluorescent or phosphorescent particles can be organic or inorganic and can be present in (solid) solution or undissolved (pigments) in the housing material or on its surface.
  • the 'luminescent body that part of the luminaire housing into which the photoluminescent particles are incorporated or to which they are superficially applied is called the 'luminescent body.
  • luminescent body With a suitably designed luminescent body, light can be collected over a large area and concentrated on decoupling points that can be easily produced in any shape. In addition to the fact that very nice decorative effects can be achieved by increasing the local intensity, luminous inscriptions and signs can be implemented easily and also very brightly because of the good use of light.
  • An example is a plate-shaped fluorescent body illuminated with fluorescent tubes on the back with decoupling points in letter form. This plate is covered on the side of the viewer by a film or plate which is at least opaque to the fluorescent light and which has transparent interruptions in the area of the decoupling points. Fluorescent body and cover plate form the front of an internally reflective Lechten housing.
  • a transparent material which matches the refractive index as closely as possible with that of the pigment. Scattering losses are thereby kept low and it is possible to form a luminescent body as a light concentrator even with luminescent pigments.
  • a solution in a transparent carrier material is often impossible or has a very serious effect on the phosphorescence.
  • clear, transparent material is provided for guiding the luminescent light.
  • the light guide in colored material is associated with losses.
  • An almost lossless light transmission through the clear, transparent material over certain areas is therefore advantageous in some applications.
  • reflectors are provided for guiding the luminescent light.
  • luminescent light that leaves the luminescent body at points where no decoupling is provided eg narrow sides of a plate
  • the possible room shapes for the light concentrator are expanded, as mirrors enable light to be guided around sharp corners.
  • reflectors are attached to the points on the luminescent body at which the light conduction cannot be maintained due to total reflection for structural reasons (e.g. brackets). This makes losses, for example avoided or reduced on brackets.
  • this cover is permeable to excitation light. This has the advantage that light incident from the observer side also contributes to the excitation of the photoluminescence.
  • luminescent substances fluorescent or phosphorescent particles
  • a luminescent body which has the advantage that the light offered by, for example, a fluorescent tube can be optimally pushed into the absorption region of a luminescent substance using auxiliary dyes.
  • a spatially inhomogeneous distribution of one or more luminescent substances in one or more luminescent bodies is provided.
  • Various decorative effects can be achieved in this way.
  • Fluorescent tubes are preferably used as light sources for the excitation of photoluminescence, since they have a high luminous efficacy and low heat development.
  • a container with a luminescent liquid or an optical fiber bundle is provided as the luminescent body, luminescent substances being incorporated into the light-conducting material.
  • luminescent substances being incorporated into the light-conducting material.
  • 1 denotes a light beam that was generated in the fluorescent tube 2. It strikes a luminescent particle 3 (for example a fluorescent dye molecule), which is incorporated into the luminescent body 4, which is designed here as a light concentrator. Luminescent light 5 is emitted and passed through total reflections in the luminescent body until it strikes the coupling-out points 6 and leaves the plate-shaped luminescent body in the direction of the observer B.
  • the decoupling points here are notches that are filled with a pigment that diffusely reflects the luminescent light.
  • the decoupling points 6 When using a phosphorescent pigment whose absorption spectrum is at shorter wavelengths than that of the luminescent light 5, the decoupling points continue to glow in the dark for up to a few hours when the fluorescent tube 2 is switched off.
  • the decoupling points 6 have the shape of letters, for example.
  • the arrangement is constructed in a housing box 9, which is provided on the inside with a reflective layer 10 (eg white paint).
  • a tubular luminescent body 4 is shown in FIG. 2, in which scattering particles 11 are also incorporated in addition to luminescent particles 3. They couple out the colored luminescent light 5 very quickly (see description of FIG. 1). Illumination is provided by a fluorescent tube 2.
  • FIG 3 shows schematically a lamp in which a Incandescent lamp 12 functions as a light source and a luminescent body 4, which is designed as a light concentrator, forms the lampshade.
