Definitions

  • This invention relates to a wall mounted luminaire in general and in particular, to an improved wall mounted luminaire producing a uniformly distributed light pattern rectangular in shape, the length of which is parallel to the wall on which the wall mounted luminaire is mounted.
  • Typical wall mounted luminaires distribute light in front of the fixture.
  • the lamp is mounted horizontally with direct flux from the lamp distributed directly in front of the luminaire.
  • a reflector positioned behind the lamp enhances the amount of light directed to the front of the luminaire and a refractor positioned in front of the lamp provides vertical control of the light but very little lateral control.
  • a typical wall mounted luminaire produces a rectangular light pattern the length axis of which is perpendicular to the axis of the lamp and the wall on which the luminaire is mounted.
  • an improved luminaire mounted on a wall comprising a lamp for emitting light, a reflector and a refractor, said reflector and refractor directing light emitting from said lamp in a rectangular pattern with the longer sides of the rectangular pattern adjacent and parallel to the wall on which said luminaire is mounted.
  • FIG. 1 of the drawings there is shown a luminaire generally identified by the reference numeral 10 mounted on a wall generally identified by the reference numeral 12.
  • the luminaire uniformly lights a rectangular pattern.
  • the luminaire 10 provides a 4:1 spacing criteria across the width of the rectangular pattern and a 6:1 spacing along the length of the rectangular pattern. With the luminaire 10 mounted ten feet high on the wall 12 a rectangular light pattern 40 feet wide and 120 feet long is provided.
  • the luminaire 10 includes a reflector 14, a refractor 16, and a lamp 18.
  • the lamp 18 has a lamp base 20 and is positioned with its lamp base 20 down and tilted toward the area to be lighted at an angle of 30° from vertical. This results in a vertical distribution of the direct flux from the lamp 18 at 60° from nadir along the centerline of the lighted area furthest from the wall. This angle increases as the lateral angle increases until the 90° vertical is reached at the 90° lateral angle. The majority of the direct flux is utilized to illuminate the desired rectangular pattern and is distributed by the prismatics of the refractor 16.
  • the reflector 14 is adapted to intercept light rays emitted from the lamp 18 to the wall 12 side of 90° laterally. Since it takes approximately 200 times more light than is provided by direct flux to obtain the 6:1 spacing along the length of the rectangle and 400 times more light than is normally provided by direct flux to reach the further­ most corner of the rectangular area to be lighted from the lamp 18, the reflector 14 reflects as much light as is physically possible to these areas.
  • the reflector 14 has a parabola shaped lower portion 20 reflecting light at an 80° vertical angle from nadir.
  • the reflector 14 has an upper portion 22 shaped to reflect light at a 15° vertical angle from nadir.
  • the refractor 16 has a face portion 24 and a bottom area 26.
  • the lower portion 20 of the reflector 14 reflects light through the face portion 24 of the refractor 16 and the upper portion 22 of the reflector 14 reflects light through the bottom area 26 of the refractor 16. This is illustrative of reflection along the vertical axis of the reflector 14.
  • the reflector 14 has outer portions 28 and 30 and inner portions 32 and 34.
  • the outer portion 28 of the reflector 14 reflects light at a 60° lateral angle crossing over through the lamp while the inner portion 34 of the reflector 14 reflects light laterally 60°.
  • the inner portion 34 of reflector 14 reflects light laterally opposite than the outer portion 30 of the reflector 14 and the outer portion 28 of the reflector 14 reflects light laterally opposite than the inner portion 32 of the reflector 14.
  • the refractor 16 has side portions 36 and 38. Both the outer portions 28 of the reflector 14 and the inner portion 34 of the reflector 14 reflect light through the side portion 38 of the refractor 16 and both the outer portion 30 of the reflector 14 and the inner portion 32 of the reflector 14 reflect light through the side portion 36 of the refractor 16.
  • cut-outs 40 and 42 are provided in the outer portions 28 and 30 of the reflector 14 to increase the amount of direct light directed to the corner of the rectangular pattern adjacent the wall 12. While the cut-outs 40 and 42 decrease the amount of light reflected by the outer portions 28 and 30 of the reflector 14 to the outer or far corner of the illuminated rectangular area, the inner portions 32 and 34 of the reflector 14 reflect a large quantity of light to the far corner of the illuminated rectangular area.
  • the cut-out areas 40 and 42 are of such a size as to allow approximately 80% of the vertical bare lamp light along the 90° lateral plane to pass directly through the refractor.
