Definitions

  • the invention relates to a reflector for a lighting device. exterior, defined by a concave reflecting surface.
  • the present invention relates, more particularly, to the street lighting.
  • the devices lighting used outdoors, especially in urban areas consist of a lantern, usually mounted on the upper end of a mast arranged near the roads.
  • this lantern can still be fixed either on a catenary wire extending, transversely, over a road, either on infrastructure bordering the latter.
  • this lantern looks like a chest and houses an optical assembly comprising a shaped reflector a shell intended to reflect the light rays produced by an electric bulb also arranged at the rear of a protective basin.
  • the present invention relates to a reflector for outdoor lighting device which has been determined surface from which result remarkable performance of the point in terms of illumination, luminance, uniformity longitudinal and general luminance, as well as the glare felt by a driver from his vehicle at a level precisely lit by a lantern equipped with such a reflector according to the invention.
  • this reflector for lighting device exterior and defined by a concave reflective surface is characterized in that its half-surface, delimited by the plane of vertical, longitudinal symmetry passes through at least 20% of points at the coordinates expressed in millimeters in Table I, in the appendix, with a tolerance of more or less 0.5 mm, the parameters A, B and C being correction constants, function of the origin ⁇ of a given spatial reference (X, Y, Z).
  • this half surface passes through at least 50% points at coordinates expressed in millimeters from the table I with a tolerance of more or less 0.5 mm.
  • a reflector 1 coming usually equip a lantern with a device exterior lighting has a concave surface S and reflective in the shape of a half-shell. Furthermore, such reflector 1 has, usually at its base 2, a flange horizontal 3 on the one hand, giving it a certain rigidity and, on the other hand, often contributing to its positioning, but also to the sealing of said lantern.
  • this reflector 1 is closed at one of its ends 4, at its opposite end 5 it has a opening 6 for the passage of the electric bulb, including the socket and its support means.
  • the most useful part 9 of such a reflector 1 is to say the part on which the qualities of the latter depend, is located, substantially, between these bosses 7; 8, 8 ', knowing that the end parts 4 and 5 only intervene very little by compared to the characteristics sought and recalled more high.
  • Such a reflector 1 also has a plane of symmetry vertical P along its longitudinal axis 10. This allows, in done, to define its shape through a set of points PT 1 to 135 located on a half surface S / 2.
  • the spatial coordinate system (X, Y, Z) of origin 0 having made it possible to define the coordinates of the points PT of table I with correction constants A, B, C, substantially equal to zero, this with respect to an example of production.
  • the coordinates of the points have not been determined exclusively with respect to such an origin 0, along the Z axis, located at the base 2 of the reflector 1.
  • the lower edge 3 defining this base 2 of the reflector 1 is ultimately higher or lower than this origin 0 without this modifying, substantially, the qualities of the reflector 1.
  • the invention extends to a reflector 1 whose half surface S / 2 intersects at least 20% of the points at the coordinates of the table I with the tolerances indicated above, said coordinates being expressed in millimeters.
