Definitions

  • the invention relates to a reflector luminaire with a reflector having at least one rotationally symmetrical or cylindrical reflector surface in accordance with the preamble of claim 1.
  • DE-PS 12 62 182 describes for the first time the darklight technology founded by Isaac Goodbar and Edison Price, which in its model concept no longer emanates from a point-like light source, as was customary before, but rather from a luminous surface that emanates is composed of an infinitesimally large number of individual light points.
  • the beam emanating from each individual light point is calculated in accordance with DE-PS 12 62 182, in order to determine the course of the curvature of the reflector.
  • a peculiarity of such darklight reflectors which applies both to rotationally symmetrical light sources (see DE-PS 12 62 182 Fig. 1) and for cylindrical, and therefore also to elongated light sources (see DE-PS 12 62 182 Fig. 2) it that the light emitted by the illuminating surface of the illuminant is invisible within a shielding space.
  • the cross section of the shielding space is from the free leg of a shielding angle and an outward extension of the plane Light exit surface formed. The prerequisite for this is that the luminous surface of the illuminant must be arranged within a specific illuminant receiving space.
  • the illuminant receiving space is located in the rear area of the reflector and is defined by the extensions of the free legs of the shielding angle, which extend into the reflector space and intersect each other and which, as mentioned above, form the shielding space outside the reflector.
  • the intersecting extensions of the free legs of all shielding angles applied to the front reflector edge thus form the front boundary of the luminaire receiving space. This boundary must not be penetrated by the luminous surface of the illuminant towards the light exit surface of the reflector if no light reflected directly from the light source via the reflector is to be visible within the shielding space.
  • the invention has for its object to make reflector lights, in particular darklight reflector lights according to DE-PS 12 62 182, largely independent of the type of illuminant to be used.
  • this object is achieved in that the luminous surface is formed by a separate flat component which diffuses the light and which is distanced from the illuminant and arranged in the front cross-sectional boundary of the illuminant receiving space or between the cross-sectional boundary and the illuminant.
  • an initially primary light source e.g. a high-voltage halogen lamp with a strongly structured surface
  • a secondary light source because the separate flat component, which diffuses the light, is to be regarded as the actual primary illuminant.
  • the diffuse light-scattering separate flat component is not arranged at an undefined point in front of the illuminant inside the reflector interior, as is the case with known frosted glass domes which serve to protect against splintering. Rather, it is, however, an unconditional requirement according to the invention that the effective surface of the separate flat component which diffuses the light is arranged at most as far as possible in the interior of the reflector at the front that it is precisely in the front Cross-sectional limitation of the lamp receiving space is located.
  • the diffusely scattering component can have grid-like light passage openings.
  • the grid-like light passage openings can be formed by a diffusely scattering component made of transparent or opaque material.
  • the diffusely scattering component can also consist of wire mesh, in which the mesh openings form the grid-like light passage openings.
  • the diffusely scattering component consists of translucent (translucent) opaque (milk glass-like) material.
  • the diffusely scattering flat component is composed of individual elements which form air passage gaps.
  • air passage gaps or air passage openings which can also be formed by light passage openings, cause air circulation, which is used to cool a high-performance lamp.
  • the diffusely scattering component according to the invention represents an essentially rotationally symmetrical body. This can, in adaptation to the intersecting extensions of the free legs of the shielding angle protruding into the reflector interior, taper towards the front, conical or be frustoconical.
  • the diffusely scattering component according to the invention expediently represents an essentially trough-like or trough-like body which is closed towards the front (ie towards the light exit surface).
  • An embodiment according to the invention which has proven particularly useful in practical use, is characterized in that the diffusely scattering component has at least one air passage opening which at the same time serves to handle the assembly.
  • Another variant of the invention is that with a compact lamp with, for example, spherical, bulb-like or the like.
  • Surface of the diffusely scattering component representing an essentially rotationally symmetrical body has the light passage opening, which is arranged rotationally symmetrical to the axis of rotation of the lamp.
  • a further embodiment according to the invention provides that, in the case of an elongated illuminant with a cylindrical surface, the diffusely scattering component, which essentially represents a trough or trough-like body, has the air passage opening which extends in a mirror-symmetrical manner to the longitudinal center plane of the lamp.
  • the diameter (for example in the case of a rotationally symmetrical diffusely scattering component) or the width (for example in the case of an essentially trough-like or trough-like diffusely scattering component) of the respective air passage opening can approximately equal to 1: 6 to 1: 7 behave.
  • Such an air passage opening which expediently represents a finger passage opening, which serves for easy handling of the diffusely scattering component during assembly or disassembly, is practically without influence in terms of lighting technology. This is because, of course, each air passage opening that also lets light through is located inside the lamp receiving space behind its front cross-sectional boundary.
  • the air passage openings which are dimensioned relatively large according to the invention, provide extremely effective cooling, in particular high-power high-voltage or low-voltage halogen lamps.
  • That cooling is improved in particular in combination with the aforementioned air passage opening in the manner of a synergistic effect in a further embodiment of the invention in that an air passage gap is formed between the outer edge of the diffusely scattering component and the adjacent reflector surface.
  • the air passage gap is interrupted by locking or fastening points between the diffusely scattering component and the reflector.
  • the reflector lamp is generally designated by the reference number 10. It is eg around a recessed ceiling light 10, which is inserted into the ceiling cutout A of a building ceiling, the ceiling face of which is designated D.
  • the reflector lamp 10 has a rotationally symmetrical reflector surface 11.
  • the reflector 12 forms in the rear area of its interior 20 a lamp receiving space 13 for a lamp 14, which can represent, for example, a low or a high-voltage halogen lamp.
  • the front region of the reflector 12 is delimited by its front reflector edge 15, which extends flush with the ceiling view surface D.
  • the reflector edge 15 delimits a flat light exit surface E.
  • a shielding space R can be seen outside the reflector 12.
  • the shielding space R is formed by the free leg S of the shielding angle ⁇ rotating about the axis of rotation y.
  • the shielding angle ⁇ is formed between the free leg S and an outward extension 17 of the flat light exit surface E. In the case of the exemplary embodiment shown, this extension 17 is synonymous with the ceiling view surface D.
  • the extensions S1 of the free legs S of the shielding angles ⁇ extend into the interior 20 of the reflector 12 and cross each other a crossing point K. If one imagines that the leg extensions S1 rotate about the axis of rotation y, the leg extensions S1 above the crossing point K form the surface of a cone 19. This cone surface also represents the front boundary 19 of the lamp receiving space 13.
  • the reflector surface 11 is designed so that light emanating from the lamp receiving space 13 is only reflected in such a way that this light is invisible within the shielding space R.
  • the flat component 18 is detachably fastened at individual points 21 or all around on the reflector surface 11 in a manner not shown, for example locked.
  • the flat component 11 can consist of a body made of translucent opaque (that is to say milk glass-like) material, for example of a plastic injection molded component.
  • the flat component 18 has air passage openings 22, which are used for air circulation to cool the illuminant 14.
  • the pointed-conical surface of the flat component 18 pointing towards the flat light exit surface E represents a luminous surface 16 which functions as a primary Illuminant met. It is conceivable that the flat component 18 has a comparative and symmetrical effect with regard to the high luminance of a luminous means 14 having a discontinuous surface.
  • the dashed line F provided on the left in the drawing is intended to indicate the course of a reflector segment which represents a wallwasher element in accordance with DE-PS 23 36 418 and shows that the arrangement shown can also be a wallwasher reflector lamp.
  • the reflector 12 as a whole can represent an elongated cylindrical component which extends symmetrically to the longitudinal center plane M into the paper plane of the drawing.
  • the illuminant 14 would also be cylindrical in this case, for example circular cylindrical.
  • the diffusely scattering flat component 18 shown in FIG. 2 forms a truncated cone-like hollow body with its narrower region pointing downward towards the light exit surface E, the small circular surface of which forms an air passage opening 23 overall.
  • the component 18 is detachably connected to the reflector 12 at the locking or fastening points 21.
  • the reflector 12 has an elongated, rectangular, slot-like latching opening 24 with its long axis over a small partial circumferential length, which cooperates with a radially short latching pin 25 with a flat rectangular cross section.
  • the component 18 has on its outer edge 27 a locking lug 26 which cooperates with the concave reflector surface 11, which is relatively closely curved at that point, in a snap-locking manner.
  • the component 18 expediently consists of a self-elastic body having a certain spring restoring force.
  • component 18 is a plastic injection-molded part made of polycarbonate, which is translucent, that is to say translucent, but due to special pigment inclusions it represents a frosted-glass, diffuse, flat body.
  • the longitudinal rectangular locking opening 24 together with the locking pin 25 ensures a flat rectangular cross section with only two locking or fastening points 21, a tilt-free radial fastening position of the component 18.
  • the air passage opening 23 which, as can be seen from FIG. 2, is located within the illuminant receiving space 13, allows an effective cooling air circulation.
  • the latter is further improved by the fact that between a circumferential air passage gap 28 is present on the outer edge 27 of the component 18 and the adjacent reflector surface 11.
  • each air passage gap extends parallel and in a straight line to the adjacent reflector surface.
  • the respective air passage gap 28 is only interrupted by the locking or fastening points 21 between the diffusely scattering component 18 and the reflector 12.
  • the air passage opening 23 also represents a finger passage opening which in a simple manner allows the component 18 to be pulled down and at the same time disengaged from its fastening position on the reflector 12.
  • An assembly of the component 18 is carried out in the reverse manner just as simply in such a way that the intrinsically elastic component 18 is pressed centrally into its fastening position with its hollow side pointing upwards.
