Definitions

  • the invention relates to a lighting device for attachment to a first, one light exit level defining wall, especially on a Ceiling, as well as for the uniform illumination of a large area and at an angle, especially at at a 90 ° angle to the second wall Wall comprising a light source in the area the first focal point of an essentially ellipsoidal Reflector element is arranged, a Lens arrangement, the one with respect to the light exit plane inclined lens, and a light exit opening, where the second focus of the Reflector element is arranged.
  • Such a lighting device is in the catalog of the applicant "luminaire program”, edition 1998/99, on page 228 under the article number 81661.
  • a light source PAR 56 500 watt / 120 V lamp provided for a ceiling mounting a room height of up to 12 m evenly illuminated. Larger room heights are included of such a lighting device in principle can no longer be illuminated satisfactorily.
  • the principle of the invention initially exists in it, instead of a PAR lamp as a light source free-radiating high-voltage halogen lamp to be used. This is essential since PAR lamps are never absolute are streak-free, which ensures uniform illumination a wall only by increased blanking in the sculpture lens is accessible.
  • the high-voltage halogen lamp Spot reflector provided the high-voltage halogen lamp partially surrounds.
  • the high-voltage halogen lamp is thereby in the focal point of the parabolic spot reflector arranged.
  • the arrangement of the high-voltage halogen lamp enables such that their longitudinal axis is perpendicular to the central axis of the spot reflector, i.e. below an angle between 0 and 45 ° to the Light exit level is the use of a high-voltage halogen lamp with a very big achievement.
  • the Heat can namely with such an arrangement chosen be directed outside the spot reflector, so that there is enough volume for cooling Available.
  • the decisive factor is the one you hit Arrangement of the high-voltage halogen lamp but also that now the light center of gravity of the light source is very concentrated in the area of the first focal point of the reflector element is placed. So that a light pipe take place in such a way that this light center of gravity in the light exit opening of the lighting device, So concentrated in the light exit plane is mapped.
  • the lighting device according to the invention enables excellent glare control, so almost glare-free, shows good efficiency lights up and illuminates the wall absolutely evenly.
  • Halogen light bulbs as a light source use as for example from the above Applicant's catalog on page 221 at the article number 81 533 emerges.
  • the halogen lamp arranged so that its longitudinal axis essentially perpendicular to the light exit plane stands.
  • the halogen light bulbs used there have a maximum output of 150 W on.
  • the chosen arrangement according to the invention has it above addition the advantage that now a change of Lamp can be done effortlessly. Because the light outlet is much larger than the one used High voltage halogen lamp, a user can use the lamp easily through the light exit opening move. The change was in the state of the art a relatively large PAR lamp more complicated because the Relative light exit opening in relation to it was small.
  • the longitudinal axis of the lamp in one to the second wall parallel plane This enables the Luminous flux so that a relatively wide Wall area of the second wall evenly illuminated can be. For a majority along one Line arranged lighting devices can therefore the individual distances in an advantageous manner the lighting devices are small from each other to get voted.
  • the lamp base protrudes at least partially from the Spot reflector out. This enables a special efficient cooling of the lamp because of the high Performance big heats, especially in the area of the lamp base. Because the lamp base protrudes at least partially from the spot reflector, is immediately adjacent to the lamp base Free space available to the thermal energy can record.
  • the invention is the spot reflector in the area of his Center flattened.
  • This is the spot reflector particularly advantageous to the location of the lamp adapted and can thus have a particularly high efficiency, i.e. allow a maximum amount of light to escape.
  • the total of 10 in the figures designated lighting device is usually attached to a ceiling 11. With the lighting device 10 is to be designated 12 in FIG. 1 Side wall are illuminated evenly. Here it is in particular side walls of a Room with a height H between 5 and 40 m.
  • Lamp an absolutely uniform illumination of the Sidewall 12 and for a user 13 almost complete glare limitation or no glare.
  • a housing 14 which, for example can also be a concrete installation housing is one Holding device 15 arranged, which in principle any way holds a spot reflector 16.
  • the Base 18 Inside the spot reflector 16 there is an unshielded one High-voltage halogen lamp 17 arranged, the Base 18 partially through an opening 19 in the wall of the spot reflector 16 from the interior 20 of the Spot reflector 16 protrudes.
  • the longitudinal axis L of the High-voltage halogen lamp 17 is therefore under one right angle to the central axis M of the spot reflector 16.
  • the central axis M of the spot reflector 16 is with respect to one through the light exit opening 21 defined light exit plane E at an angle ⁇ inclined.
  • the longitudinal axis L of the High-voltage halogen lamp 17 at an acute angle ⁇ (as shown in Fig. 2) with respect to the light exit plane E of the lighting device 10 stands.
  • the angle ⁇ is dependent on the room height H. to choose. In the embodiment shown in the figures the angle ⁇ is approximately 17 °.
  • the angle ⁇ is approximately 6 °.
  • the parabolic spot reflector 16 has in Area of its light exit opening 22 a directionally neutral, clear, hardly structured lens 23 on.
  • the main purpose of the diverging lens is a reduced amount of light to one of a kind Wallwasher scoop formed ellipsoidal Throw reflector element 24. That on its hollow side 25 mirrored reflector element 24 serves to the upper area 12a of the wall 12 soft and streak-free to illuminate.
  • the scattering lens 23 serves as it were as a link between the direct light component and the amount of scattered light.
  • the amount of scattered light is via the reflector element 24 in the upper wall area Thrown 12a.
  • the scattered light component the light that comes from the high-voltage halogen lamp 17 coming from the lens 23 and deflected is thrown onto the reflector element 24.
  • This Light can then emanate from the reflector element 24 or the mirrored hollow side 25 through the light exit opening 21 of the lighting device 10 ejected and especially the upper wall area 12a of the wall 12 to be illuminated.
  • the high-voltage halogen lamp 17 is arranged in such a way that the center of gravity of the high-voltage halogen lamp 17 in the area of an upper focal point (approx P1) of the reflector element 24.
  • the arrangement is such that the lower, second focal point P2 in the light exit opening 21 the lighting device, in particular in the light exit plane E.
  • the high-voltage halogen lamp 17 is one essentially M-shaped spiral, not shown arranged.
  • the arrangement of this filament can be for example from the catalog of the Applicant, page 372 in the last column.
  • the actual light volume, which you can also call Light center of gravity is very spatial limited and therefore concentrated around the first focus P1 of the reflector element 24 arranged around.
  • the spot reflector 16 is relative to the reflector element 24 arranged such that the focal point of the parabolic spot reflector 16 with the first Focus P1 of the ellipsoidal reflector element 24 coincides. It is advantageous above also the spot reflector 16 in the area of its center Z flattened. This enables one particularly high efficiency of the lighting device according to the invention.
  • a lens arrangement 26 is provided which on the one hand can have an expanding lens 27, which essentially serves to prevent the emerging Light oval (with reference to Fig. 2 out of the paper plane) spread out to the widest possible wall area illuminate, or the distance of several, lighting device arranged along a line 10 to keep each other low.
  • a darklight reflector arrangement can form below the spreading lens 27 28 are the glare-free guaranteed because in the direction of the wall 12 high dimming occurs.
  • the base 18 of the high-voltage halogen lamp 17 is releasably attached to a socket body 29, which in heat-conducting connection with a heat sink 30 stands.
  • a heat sink 30 stands.
  • die-cast aluminum existing heat sink 30 can be of a variety of Have cooling fins 31. This is how it works even with powerful high-voltage halogen lamps 17 sufficient cooling with 500 watts to ensure.
  • the high-voltage halogen lamp is actually 17 arranged such that the longitudinal axis L of the high-voltage halogen lamp 17 in a plane parallel to the second Wall 12 lies. Accordingly, correct drawings should be made in a sectional view according to FIG. 2 show a spot reflector 16 in the area of opening 19 shown continuously (ie without opening) would be trained as well as a high-voltage halogen lamp 17 in a sectional view transverse to it Longitudinal axis L, as shown in Fig. 3.
  • Replacing the high-voltage halogen lamp 17 is designed in the lighting device according to the invention 10 particularly easy because the Light exit opening 21 of the lighting device 10 is much larger than the lamp 17.
