Definitions

  • the invention relates to a device for blinding outdoor lights comprising a substantially cylindrical, translucent defogger having a surface which is profiled in a zigzag shape in the axial direction, so that the radiation of a luminous means which impinges on the defibrillator, in a desired direction is deflected.
  • Such devices are used in particular in luminaires with high luminance. They prevent direct insight into the light source. This is particularly important in outdoor areas, where a dazzling of the leader of motor vehicles or passers-by should be avoided and directed light is needed for better illumination of the roads.
  • From the EP 0 191 264 is an arrangement for de-glare outdoor lights with large-area radiating bulbs is known in which a plurality of identical rings are stacked with a right triangle as a cross section.
  • the rings have holes in which threaded rods are provided for connecting the rings with each other.
  • the arrangements are usually made of plastic manufactured.
  • the outer profile of the composite assembly is smooth cylindrical and the inner profile is zigzag in the axial direction.
  • Each ring of the inner profile has a surface in the radial direction and a surface inclined by 40 ° thereto.
  • the thus constructed cylindrical Verblend emotions is arranged around the lamp around. The radiation of the illuminant is then refracted as in a prism and deflected to a large extent in the axial direction downwards. Another part of the radiation is deflected upwards.
  • the object is achieved in that the wedge-shaped projections of the zigzag profile are formed in a first region such that the radiation of the lamp is totally reflected in the desired direction when passing through the anti-glare body and the wedge-shaped projections of the zigzag profile are formed in a second region in that the radiation of the luminous means is refracted in the desired direction as it passes through the antiglare body.
  • the radiated upwards radiation component can be reduced. Radiation components which can not be deflected downwards by refraction can also be conducted downwards in the desired direction in this arrangement. For this purpose, no separate mirror or the like is required.
  • the angle of the wedge-shaped projections the emission characteristic can be further optimized. As more radiation is radiated down, lamps of lower power can be used, or a better lighting result is achieved. A disturbance by light smoke is avoided.
  • the EntblendSh is integrally formed. Then no separate connection means, such as threaded rods or the like, are used. This makes it possible to manufacture the glazing body made of glass, since the risk of glass breakage is reduced when connecting.
  • the radiation emitted by the illuminant always has a UV component. Unlike plastic, glass does not yellow when irradiated with such UV rays. Glass is also more thermally stable than plastic.
  • the zigzag profile is provided on the outside of the anti-glare body.
  • the anti-glare body can be prepared by pressing a punch into the liquid material in a mold and pulling it out after curing. Due to the shape, the zigzag-shaped outer profile can be produced reproducibly and very accurately.
  • the Entblend stresses is internally conical.
  • the half the opening angle with respect to the axis of symmetry of the cylindrical arrangement can be in the range of 0.5-3 °, preferably at 2 °. This facilitates the extraction of the stamp during manufacture.
  • cylindrical lenses are integrally formed on the inside of the defibrillator whose axes of curvature extend in the axial direction.
  • Such cylindrical lenses are particularly useful when using bulbs with small burners, such as innovative high-pressure lamps with crystal clear pistons.
  • the zigzag profile is provided on the inside of the anti-glare body.
  • the anti-glare body can also off Plastic, in particular polycarbonate be made.
  • the preparation can be carried out by pressing a translucent plastic into a planar shape with a zigzag-shaped surface and bending the mold thus produced, such that a segment of the anti-glare body is formed. Subsequently, two or more segments are joined together to form a complete defoaming body.
  • the zigzag-shaped profile may also lie on the inside, since then no stamp must be removed.
  • a light-permeable heat shield is preferably provided in the interior volume of the anti-glare body.
  • Such a heat shield can be formed by a coaxial with the anti-glare body arranged, cylindrical glass body. As a result, the heat from the lamp is kept substantially away from the plastic body.
  • cylindrical lenses are formed on the inside of the heat shield, whose axes of curvature extend in the axial direction. These cylindrical lenses have the same function as above. They avoid glare on direct inspection of the light source.
  • an auxiliary diaphragm can be provided outside the anti-glare element for glare control of selected angular ranges in the circumferential direction.
  • the auxiliary panel may comprise prisms whose roof edge extends in the axial direction and which are positioned side by side in the circumferential direction. It is often the case that e.g. in street lighting, although the walkway and the street should be lit, but not behind the light lying and opposite houses. The angular range in these directions should therefore be as completely as possible blinding. With an auxiliary diaphragm, the radiation emitted in these directions can be deflected in a desired direction.
  • the auxiliary diaphragm can have a curvature on the side facing the anti-glare body, the center of curvature of which coincides with the center of the illuminant.
  • a generally designated 10 part of an outdoor lamp is shown.
  • the outdoor light 10 comprises a support 12, a shielding body 14 and a socket 16 for a lighting means.
  • a part of the luminous means 18 is visible in the view in FIG.
  • the anti-glare body 14 has a lower edge 20. This edge 20 is held in a groove 22 in mounting clips 24.
  • the mounting clips are inserted into receptacles 28 provided for this purpose on the carrier 12.
  • the Entblend stresses 14 is held in four such mounting clamps, which are arranged uniformly along the circumference.
  • the carrier is a casting and is mounted inside the outdoor lamp.
  • the Entblend Sciences 14 is substantially cylindrical and rotationally symmetrical.
  • the Entblend Sciences 14 is profiled on both the outside 30, as well as on the inside 32.
  • On the inside 32 depending on the dimensions between 20 and 80 adjacent cylindrical lenses are formed.
  • 60 cylindrical lenses are provided for a shield with a smaller radius of 65 mm.
  • the cylindrical lenses have a radius of curvature of 2.9 mm.
  • the cylindrical lenses extend over the entire length of the Entblend stresses 14th
  • eleven projections 36 were selected. With this number, it is ensured that the arrangement does not become too thick similar to a Fresnel lens.
  • the lowermost two projections 48 and 52 are flat and have a large wedge angle 38.
  • the wedge angle 38 initially becomes smaller towards the top, assumes a minimum and then becomes slightly larger again.
  • the inclination of the upper boundary surface 42 of the projections relative to the horizontal 54 decreases towards the top.
  • the inclination of the lower boundary surface 44 of the projections with respect to the horizontal 54 increases towards the top.
  • the wedge angle 38 is not symmetrical about the horizontal.
  • the lower angle 40 therefore does not necessarily correspond to half the wedge angle 38.
  • the anti-glare body can be manufactured in one piece or also from several sub-segments.
  • the anti-glare body results in a transmission characteristic, as shown schematically for visible light in Fig. 4 is.
  • Radiation uniformly emitted from a punctiform light source 60 strikes the inside 62 of the anti-glare body 14. At the interface, it is refracted a first time. In the area below the horizontal, the radiation is deflected slightly upwards. In the area above the horizontal, the radiation is deflected slightly downward. At both surfaces 42 and 44 of the lower two projections, the radiation exits the defoaming body again. The radiation 64 is deflected downward.
  • the overlying protrusions are formed so that the radiation exits downwardly only at the upper surface 68, with corresponding refraction, and not at the lower surface 70.
  • the wedge angles of the protrusions are correspondingly acute, causing the entire radiation to be deflected downwardly.
  • the overlying topmost projections are formed so that the radiation impinges on the top surface 72 at an angle below which total reflection occurs. The radiation is thus totally reflected at the upper surface 72 and emerges with refraction at the lower surface 74 of the projection. In this way, the steeply upwardly radiated radiation components 76 are deflected from the light source 60 without further mirrors or other optical elements down. The entire radiation of the light source is emitted comparatively evenly down to a preferred angle range.
  • bulbs with very small burners and crystal clear pistons such as high-pressure lamps, metal halide lamps or sodium vapor lamps with short burner technology.
  • the arrangement is still suitable with fluorescent lamps that radiate over a large area. Due to the heat resistance of the material, the lamps can also work with powers up to 200W.
  • FIG. 5 shows the effect of the cylindrical lenses on the radiation of a punctiform light source 78.
  • a segment of the anti-glare 14 is shown.
  • cylindrical lenses 80 are formed on the inside of Entblend analysess 14 .
  • the cylindrical lenses 80 have a radius of 2.9 mm.
  • the axis of curvature 82 extends parallel to the axis of symmetry of the anti-glare body, which in the present case coincides with the position of the point light source 78.
  • a plurality of cylindrical lenses are arranged. Between the cylindrical lenses in each case an oppositely curved connection point with a radius of 0.5 mm is provided at the transition.
  • the cylindrical lenses act as a converging lens and focus the radiation from the light source 78 in a plurality of likewise perpendicular lines 84. Otherwise, the radiation remains evenly distributed along the circumference.
  • the use of the cylindrical lenses has the advantage that even if the viewer receives direct insight into the light source, when he sees from a certain angle in the bulb, only a part of the radiation is illuminated. Namely, the radiation is distributed to a plurality of points. The glare is significantly reduced.
  • the bulb is optically broadened.
  • FIG. 6 shows how the radiation 86, which strikes a prism 88 from a small angular range, is totally reflected at surfaces 90 and 92 and emitted laterally 94. This effect can be used to block the radiation in certain directions and to deflect it in a desired direction.
  • an auxiliary aperture 96 is shown, which is composed of 5 such prisms.
  • the inner sides 98 of the prisms run essentially along a circular arc whose axis of curvature coincides with the axis of curvature of the anti-glare body (not shown).
  • the auxiliary panel 96 With the auxiliary panel 96, radiation that falls in an undesired direction, for example on the house facade along a street, can be deflected in a desired direction, for example along the street.
  • the mean angular range of 86.6 ° remains free of radiation.
  • FIG 8 an arrangement is shown in which a glare by means of cylindrical lenses 100 takes place and an auxiliary aperture 102 is provided. It can be seen that the effects are essentially retained even when they are combined.
  • the auxiliary diaphragm 102 can be provided with cylindrical lenses 104, as shown in Fig.9.
  • a defoaming in a further embodiment is instead of plastic glass, eg R ⁇ HM Hw55, a PMMA mixture with polycarbonate portions and a service temperature of about 105 ° C, or pure PMMA or OROGLAS HT 121 made.
  • a glass cylinder 108 may be provided as a heat shield between the plastic anti-glare body 106 and the lighting means 110 (FIG. 10).
  • the cylindrical lenses are formed in this two-part variant of the glass body.
  • the anti-dazzle body 106 made of plastic also has projections which form a zigzag-shaped profile. Also on this profile, the radiation is totally reflected or broken down. However, the profiling is located on the inside of the anti-glare body. The outside is smooth. To produce this defoaming body several segments are produced, which are then joined together. Each segment is first pressed flat and then bent.
  • FIG. 11 shows a section of a vertical section through a shielding body 112.
  • the outer side 114 of the shielding body is smooth.
  • the inside 116 of the anti-glare body is profiled like a prism. It can be seen that the angle 118 relative to the horizontal 120 increases towards the bottom. In this way, the radiation is concentrated in a selected direction.
  • the profiling is aligned with the lamp axis 122.
  • FIG. 12 shows a plan blank 124 in a perspective view.
  • prisms are formed on one side 126 of the blank 124 prisms are formed.
  • cylindrical lenses are formed on the opposite side 128 cylindrical lenses are formed.
  • the prisms extend in a direction perpendicular to the axis of curvature of the cylindrical lens on the surface of the blank 124.

  • the roof edges 136 of the original prisms now form a 120 ° segment of a circle.
  • a connecting rail 140 is provided with H-shaped cross-section. The rail is pushed onto the edges of the blank 134.
  • three blanks 134, 142 and 144 assembled by means of rails 140 to a defoaming. This is shown in FIG. 16.
  • the blank 134 is externally provided with cylindrical lenses whose axes of curvature is parallel to the axis of curvature of the blank.
  • the assembled into a cylinder blanks 134, 142 and 144 are placed on a support 146 and bolted there or otherwise secured.
  • the carrier 146 also serves to secure the socket 148 for the illuminant 150.
