Definitions
- the invention relates to a mirror slat for glare control of lights with a annular lamellar body with a concavely curved in the radial planes Ring surface that of a circular inner edge and a circular
- the outer edge is limited, the diameter of the inner edge being smaller than that Diameter of the outer edge and the surface of the lamellar body with a reflective material is provided, the mirror lamella with at least one perpendicular to the plane of the reflector defined by the inner edge is provided.
- Such mirror slats are used to glare large light sources in Lights used.
- the lights can also be found as street or Path lighting use.
- the lamellae are ring-shaped and become ordinary placed on one another.
- the rings usually have a frustoconical or concave curved mirrored ring surface. The light emitted by the light source can then exit diagonally downwards only in certain directions, so that the Example drivers are not dazzled.
- a disadvantage of the known lamella arrangements is that the light is always is radiated radially around the lamp. The residents of a street can are disturbed by the light emitted by a street lamp in their direction.
- a lampshade for a street or square light in which a plurality of slats are arranged one above the other.
- a mirror reflector cuts the slats in segments.
- the specular reflector extends over the entire Height of the arrangement.
- the use of the mirror reflector creates an asymmetrical one Light distribution.
- the mirror reflector consists of one piece and is by means of screws or rivets attached to the top and bottom slats.
- the object is achieved in that the reflector surface is curved or faceted and the slat body with the reflector surface in one Piece is made .. This way one direction can be completely dimmed and that Light can be directed in another desired direction. It will be asymmetrical Lighting reached.
- the reflector surface is curved. It is preferred Parabolically curved reflector surface.
- Two meeting Reflector surfaces preferably form a larger angle with one another than the two other reflector surfaces.
- the reflector surfaces that make the larger angle with each other can be arranged, for example, in the direction of the residential side of a street be so that a larger dimming is achieved here.
- the reflector surfaces preferably describe a parabola, the axis of symmetry thereof forms a non-zero angle with the straight line through the vertex, which is perpendicular to the diameter that connects the axes on which the Reflector surfaces meet. Surprisingly, it has been shown that this is a causes particularly good alignment of the radiation.
- the reflector surfaces each belonging to a pair of reflector surfaces point in one preferred embodiment, the same curvature. This will introduce the Asymmetry the same on both sides.
- the reflector surfaces can have an upper edge in the plane of the inner edge of the Have lamellar body, and at least a part of each reflector surface can on the Side of the parabolically shaped surface of the lamellar body can be arranged.
- the reflector surfaces can have a lower one Have edge in the plane of the outer edge of the slat body and at least one Part of each reflector surface on that of the parabolically shaped surface opposite side of the slat body may be arranged. Both parts of the Reflector surface help to align the radiation and dazzle.
- the lamella can be stackable. Passages are preferably provided, which at stacked mirror slats are arranged one above the other and through which one Fastening element can be pushed through for fastening the mirror slats with each other and / or for fastening the mirror slats to a holder. Then can the slats can be easily stacked on top of each other.
- the passages can be arranged around the axes at which the reflector surfaces meet.
- a projection is preferably provided on one edge of each reflector surface and a groove on the opposite edge of the reflector surface, the Head start in the groove of one with stacked mirror slats engaging adjacent mirror slat. This makes the slats stackable improves and the orientation of the angle at which the slats are stacked around the common central axis lie, simplified.
- At least one stabilizing pin is provided, which is perpendicular to the through the plane defined by the inner edge. This will cause the slats to tilt against each other and the stability of the stacked slats improved.
- the surface is on the concave curved ring surface opposite side of the lamellar body stepped. This will make the number of reflections needed for everyone Light beam minimizes and prevents light from emerging horizontally or upwards.
- the steps are preferably in the direction of the outer edge of the lamellar body flatter and have a larger angle. This will cause a slight fluctuation in thickness the slat reached. Thickness fluctuations can lead to the Manufacture the still hot material in the thick areas of the slat body more contracts than in the thinner places. The effect causes sink marks on the Top of the slats, which can affect the quality of the direction of reflection.
- the smallest angle of the steps on the inner edge of the lamellar body is preferably about 90 degrees and the largest angle of the steps on the outer edge of the slat body about 120 degrees. A particularly good radiation quality is achieved with this angular range the directions reached.
- the lamella can be made from an injection molding process Polycarbonate exist. But it can also be made of temperature-resistant plastic a continuous use temperature up to 180 ° C if this is due to high Luminosity with the corresponding high temperatures is necessary. It is still it is possible to manufacture the slats from die-cast aluminum using die-casting technology.
- a particularly good reflectivity is achieved if the lamella is coated with a primer is provided and they as a whole with a reflective vaporized in a high vacuum Layer is provided.

- the polar diagram of the lamp described is shown in FIG. In it the radiated intensity in kd / Klm depending on the radiation angle ⁇ .
- the Angle ⁇ is the angle that a beam forms with the vertical. As at the beginning radiation in the horizontal direction at 90 ° is undesirable and a high radiation at about 60 ° is aimed for.

- the associated Isolux diagram is shown in FIG. 16.
- the intensity is shown depending on the horizontal position.
- a street for example, would go from right to left in Fig. 16 and the resident side could be arranged below in this example.
- the Reflector surfaces 14, 16, 18, and 20 become a deviation from the rotational symmetry reached.
- the diagram clearly shows that the "range" of the lamp is towards along the street has become larger and smaller in the direction of the residents. Thereby the lamps can be spaced from each other, resulting in cost and Energy savings.
- the slats are made of polycarbonate in one piece by injection molding. She are pre-painted and vaporized with reflective material in a high vacuum.
