  • This module has a horizontal optical axis XX and comprises at least one light source S, and a reflector R with a surface of complex type. The geometric axis of the reflector R coincides with the optical axis XX.
  • Sections such as 1 of the reflector R by vertical planes parallel to the optical axis XX are substantially in parabolic arcs, turning their concavity forward, that is to say to the right according to Fig. 1 . These sections have a focus located in the horizontal plane passing through the optical axis XX of the module.
  • the arc 1 corresponds to the section of the reflector R by a vertical plane passing through the optical axis XX, and has a focus F located on this axis.

  • the section of the reflector R by a horizontal plane passing through the optical axis is substantially in an elliptical arc 2 ( Fig. 2 ) admitting a first focus F1 coincides with the focus F or neighboring this focus, and a second focus F2 located forward on the optical axis of the module.
  • the reflector R of the complex surface type produces a cut beam to the front.
  • the cutoff may correspond to a flat line, in particular horizontal for an anti-fog function. It may also correspond to a flat but oblique line, in particular to participate in the formation of the oblique part of a cross-type beam (which, according to European regulations, presents a cut in the form of a broken line comprising a horizontal plane segment and an oblique plane segment at 15 °).
  • a cylindrical lens L with vertical generatrices is placed between two planes passing through the foci F1 and F2 of the ellipse arc 2 and orthogonal to the optical axis.
  • the lens has a general shape of a diverging lens, of which at least one zone may not be divergent.
  • the light source S is constituted by at least one light-emitting diode 3, abbreviated as LED.
  • the emitter of the LED 3 is of the rectangular or square plane type, with 1 to 5 mm of side.
  • the focal length of the reflector R is of the order of 5 mm for such emitters.
  • the LED 3 is arranged so as to illuminate downwards with the mean direction ⁇ of its light beam substantially vertical and orthogonal to the geometric axis of the reflector R.
  • This reflector R is located, relative to the plane of the rear face 4 of the LED, entirely on the side of the beam emitted by the LED 3.
  • the surface of the reflector R is calculated taking into account the optical protection of the LED 3.
  • the leading edge of the LED 3 is located at the focus F and the LED extends rearward from the focus F.
  • the collector reflector R is such that at each point of this reflector light rays such as i1 from the front edge of the LED 3 are reflected horizontally along a radius such as r1, or so as to define an oblique planar cut line up to 15 ° on the horizontal.
  • the rays such as i2 emitted by LED 3 points located behind the front edge are reflected in rays such as r2 falling below the horizontal. With this arrangement, the illuminated area is therefore below a horizontal cut or an inclined cut rising on the horizontal.
  • the LED 3 is then placed so that its trailing edge passes through the focus. F and LED 3 is located in front of this fireplace.

  • the lens La, before folding the beam must exceed the reflector up, while in the case of Fig. 1 and 2 the lens L must extend beyond the reflector downwards because the beam diverges all the more as it is further away from the reflector.
  • the closer the lens L, La is to F2 the more potentially it is narrow (the width corresponds to the dimension in a direction perpendicular to the plane of Fig. 1 ) since the beam in top view converges to F2; however, this effect is partially or totally canceled depending on the source chosen and its orientation due to the divergence due to the size of the source.
  • the module M of Fig. 1 and 2 offers a high yield. It makes it possible to obtain a satisfactory luminous flux for a reduced electrical energy consumption, but does not lend itself well to vertical stacking, on the one hand because of the arrangement of the radiator 5 and on the other hand because the LEDs will not be located in the same plane, which prevents them from being placed on a single circuit board and complicates the electrical connections.
  • modules can be juxtaposed horizontally, with the rear faces of the LEDs in the same horizontal plane, for mounting on a single horizontal printed circuit board.

  • a reflecting mirror 7 plane is disposed below the reflector Ra to return the beam to the lens La with vertical generators.
  • the mirror 7 is inclined, preferably at 45 °, on the horizontal plane.
  • Fig. 3 it is then possible to vertically stack several modules, for example three similar modules Ma, Ma1, Ma2 whose rear faces 4a, 4a1, 4a2 LEDs 3a, 3a1, 3a2 are located in the same vertical plane 6 and can be fixed and connected on the same vertical printed circuit board 8.
  • Radiators 5a, 5a1, 5a2 are disposed behind each respective LED; alternatively the radiators could be grouped into a single common radiator.
  • the LED 3a Due to the reversal of the beam created by the reflecting mirror 7, the LED 3a is arranged such that its upper edge is substantially at the focal point Fa of the reflector Ra.
  • the light rays such as i3 from areas of the LED 3a located lower than the focus are reflected downwardly by Ra away outwardly, and then reflected by the mirror 7 along radii such as r3 following a downward direction.
  • the lens La is common to the three modules and has a height sufficient for this purpose.
  • PBL Progressive Bending Lignt
  • the reflecting plane mirror 7 of a module is fixed to the back of the reflector Ra1, Ra2 of the module located below and forms a single piece with this reflector.
  • the input face 9 of the lens La may have recesses at the transition zones between the different modules while the exit face 10 of this lens is smooth, without recess.
  • the reflectors R, Ra, Ra1, Ra2 of "complex surface” type are adapted to the LEDs 3. Indeed, given the target focal lengths (of the order of 5 mm for light emitters of 1 to 5 mm side) , you have to take into account the protection optics of the LEDs.
  • This case corresponds to a protective optics of the blade type or plate with parallel faces.
  • a method for calculating the cross-sections for the two families of LEDs above (1a, 1b) is given below for a direction parallel to x (axis of the marker, itself parallel to one of the sides of the emitter ), in the case of a low cut, dead zone at the top after folding and assembly.
  • the exposed calculation method is an elementary numerical solution of the underlying equation, which is a differential equation.
  • a suitable tangent cylinder at any point P current of the parameter curve and thus construct the complete surface (this surface is the inner envelope - that is, the source side - of this infinity of cylinders).
  • this surface is the inner envelope - that is, the source side - of this infinity of cylinders.
  • one calculates a section of each of the cylinders belonging to the desired envelope, cut by a vertical plane containing P parallel to the radius coming from F1 after reflection at P.
  • the calculation of the cross section of the cylinder is carried out as above after projection of F and the emitter on a vertical plane passing through P and containing the normal to the parameter curve, generally elliptical, in P. Hs and f then have different values for each point P.
  • the parameter curve is an elliptical arc of F and F2 foci.
  • F and F1 are merged or substantially merged, but this is only an example, and F and F1 can also be distinct.
  • the output lens is constructed as a function of a horizontal deflection parameter of the images which makes it possible to control the shape of the iso illumination curves on a measurement screen and the total width of the beam.
  • a horizontal deflection parameter of the images which makes it possible to control the shape of the iso illumination curves on a measurement screen and the total width of the beam.
  • the principle used consists in transforming a spherical wave coming from a corner of the emitter (F, as above) into a spherical wave of center F2.
  • the calculation obviously takes into account the deviations due to the protective dome (which is not centered on the focus).
  • the procedure is relatively simple, which comes from the fact that it is desired to make a low-cut beam, regardless of the choice of a beam converging in a top view towards F2.
