Definitions

  • Classical lamps with a reflector formed by a smooth parabola and with optics on refractor or with optics formed by basic reflexive elements on reflector are characterized in having a flat curve of luminous intensity distribution that may not be able to provide an optimal reaction of an observer to the lamp signalization.
  • a lamp according to the present invention which is comprised of a reflector, a refractor and a light source, whereby, said reflector having its basic surface spherical, paraboloidal, ellipsoidal or hyperboloidal, is provided with convex or concave basic reflective elements. Corners of said basic reflexive elements are placed on the basic reflector surface, the working surface of said basic reflective elements is of Bézier's type or this surface has a shape of a circle or an ellipse in the horizontal and vertical sections. In the corners of said basic reflexive elements said reflector is provided with concentration elements.
  • the reflexive surface of said concentration elements has the creating curve in a conic shape, whereby, said curve can be rotationally symmetrical or it is cylindrical, toroidal or in the shape of parabolic cylindres with horizontal or vertical position of the cylinder axis.
  • the refractor is provided with optical elements of low deviation or with decorative optics on the functional surface, eventually with optical elements with vertical, horizontal or vertical and horizontal deviation.
  • Said light source is in the shape of a cylinder which is placed laterally in the vicinity of the relector focus.
  • the front direction indicating lamps mounted in the vicinity of the light-emitting surfaces of the main headlamps, for the rear fog lamps, where, according to the present invention, it is possible to increase luminous intensity in horizontal and vertical sections by means of a linear ray deviation away from the normal line to the horizontal and vertical surfaces of the concentrating reflexive elements or for the rear break and position lamps.
  • Figure 1 shows a lamp in front view.
  • Figure 2 shows a lamp in vertical section made along the plane A-A as shown in Figure 1 and
  • Figure 3 shows a light beam of the lamp in projection into the perspective road projection.
  • a lamp for motor vehicles is comprised of a reflector 1 , a refractor 2 and a source 3 , e.g. of cylindrical shape mounted laterally with regard to the axis x of the lamp in the vicinity of the focus F of the reflector 1 .
  • the reflector 1 having its basic surface 10 spherical, paraboloidal, ellipsoidal or hyperboloidal is provided with convex of concave basic reflexive elements 5 so that the corners 6 of the basic reflexive elements 5 are placed on the basic surface 10 of the reflector 1 .
