Definitions

  • the present invention relates generally to motor vehicle headlamps, and more particularly to the means to be used to enable a vehicle provided with crossing headlamps for a given direction of traffic (for example traffic on the right for continental Europe). to be able to drive in a country where traffic is in the opposite direction (eg traffic on the left for the United Kingdom) without dazzling drivers of vehicles traveling in the opposite direction.
  • a given direction of traffic for example traffic on the right for continental Europe.
  • traffic for example traffic on the right for continental Europe
  • a passing beam for traffic on the right is typically defined by an upper "V" cut, consisting of a horizontal half-plane to the left of the road axis and a half-plane inclined upwards. approximately 15 ° from the horizontal to the right of the road axis.
  • the horizontal half-cut on the left makes it possible not to dazzle drivers of vehicles traveling in the opposite direction, while the half-cut back to the right makes it possible to illuminate the aisle of the road and to guarantee the visibility distance to the right. . It is therefore understandable that, when a vehicle thus equipped circulates in a country where traffic is on the left of the road, the part of the beam located under the rising half-break will dazzle the drivers of the vehicles traveling in the opposite direction, which seriously compromises the safety of the traffic.
  • the known solution if it answers the problem posed, that is to say to avoid the glare of the drivers traveling in the opposite direction during a change of direction of circulation, is however unsatisfactory in that it consists in obscuring a a significant part of the beam emitted by the headlamp, thus to reduce the luminous flux illuminating the road situated in front of the vehicle, and consequently to reduce the visual comfort of the driver during the night driving, and all the more so as this driver circulates in a direction of circulation to which he is less accustomed than the sense in which it circulates ordinarily, and that he may not have all his reflexes.
  • Such a solution is, however, hardly applicable to other categories of projectors, for example so-called "elliptical" projectors in which a light source is placed at a first focus of a recuperating mirror and concentrator of the ellipsoidal kind, the luminous flux thus being concentrated in a luminous spot at the second focus of the ellipsoidal mirror, which is confused with the focal point object of a convergent lens, which then projects on the road the desired illumination beam.
  • elliptical projectors in which a light source is placed at a first focus of a recuperating mirror and concentrator of the ellipsoidal kind, the luminous flux thus being concentrated in a luminous spot at the second focus of the ellipsoidal mirror, which is confused with the focal point object of a convergent lens, which then projects on the road the desired illumination beam.
  • the cut is generated by a cover or screen placed in the immediate vicinity of the object focus of the converging lens, which directly obscures the light spot. It is generally considered that there is no zone on the protective glass located downstream of the lens directly associated with the annoying light immediately below the upgoing half-break. It can be considered, roughly, that each elementary zone of the lens, and consequently each corresponding zone of the protective glass, contributes to projecting the entire beam.
  • the present invention is placed in this context and its purpose is to avoid these drawbacks by proposing, in particular for a projector of the elliptical kind, to achieve the adaptation of the geometry of the light beam imposed by the change of the direction of the traffic by means that are substantially as simple to implement and as inexpensive as the holiday caches described above, that is to say by affixing to a certain area of the protective glass of the headlight an adaptation device such as the light emitted by the headlamp and located below the upgoing half-break, located by construction of one side of the light beam emitted by this headlamp for a given direction of circulation, is eliminated from the beam emitted by the headlamp so that it is not more dazzling for drivers of vehicles traveling in the opposite direction when the vehicle thus equipped is subjected to a reversal of the direction of traffic , while retaining the entire luminous flux emitted by the projector, and the photometric characteristics of the latter.
  • the method comprises the additional step of horizontally deflecting the light rays passing through the second region of the surface of the protective glazing so that they are located in the part of the passing beam below the horizontal and distributed in this part of the passing beam
  • the present invention also relates to an adaptation device for implementing this method.
  • the adaptation device is intended to be interposed in the path of a portion of a light beam emitted by a crossover projector of the elliptical kind for a motor vehicle comprising, upstream of a non-protective glass deviating or weakly deviating from the light, a light source emitting light rays to a recuperating mirror and concentrator which returns them towards a convergent lens to form, in cooperation with a cache a passing beam comprising on both sides an optical axis having a substantially horizontal half-cut extending from one side of the optical axis and a half-cut located above the horizontal extending on the other side of the optical axis, the device being intended to adapt the portion located above the horizontal of the light beam emitted by the headlamp when the vehicle is traveling in a reverse direction of traffic to that for which the projector has been designed, and it consists of a transparent material and deflector of light.
  • the present invention also relates to a template for carrying out the method described above.
  • the template defines the second region of the protective glass of the projector on which the adaptation device is to be arranged.
  • the template is adapted to the total shape of the protective glass of the crossing headlamp and it defines the second region of the protective glass of the projector on which it must be arranged the adaptation device.
  • a subject of the present invention is a crossing headlamp of the elliptical type for a motor vehicle, comprising, upstream of a non-deflecting or slightly deviating light protection glass, a light source emitting light rays towards a recuperating and concentrating mirror. which returns them in the direction of a convergent lens to form, in cooperation with a mask, a passing beam comprising on both sides of an optical axis a substantially horizontal upper half-cut extending on one side of the optical axis and a half-cut located above the horizontal extending on the other side of the optical axis, the passing beam being adapted to be adapted by a method as described above.
  • the protective glass is provided with a laying template as described above.
  • the protective glass is provided with an adaptation device as described above.
  • a projector of the elliptical kind to which the present invention can be applied Such a projector conventionally comprises a light source S, such as for example the filament of an incandescent lamp or the electric arc of a discharge lamp.
  • the light source is located in the vicinity immediate of a focal point object F o of a recuperating mirror and concentrator M of ellipsoidal shape, which furnishes to its focus image F; the image of the source S in the form of a light spot having an appropriate distribution of the light within this spot.
  • a convergent lens L for example plano-convex, is disposed downstream of the mirror M, so that its object focus F L coincides with the image focus F; In this way, the lens L projects a beam of substantially parallel rays to illuminate the road in front of the vehicle, through a protective glass G, this ice being smooth, ie not deviating or weakly deviating .
  • the mirror M is a mirror capable of generating by itself a light spot having a certain spread in width, as described in documents FR-A-2 704 044 and FR-A-2 773 604 in the name of the Applicant.
  • a fixed or retractable cover CA makes it possible, in known manner, to conceal a part of the light spot in the vicinity of the focus F L of the lens L, so that the lens L projects on the road a passing beam delimited by an upper cutoff of determined configuration. If the CA cover is retractable, the retracted position of the latter leaves the bright spot intact, so the lens L projects on the road an unbroken beam of road.
  • FIG. 3A The passing beam generated when the CA cover obscures part of the light spot is a passing beam to European standards, for example for right-hand traffic, and its distribution is illustrated in Figure 3A.
  • This Figure represents the intersection by a screen perpendicular to the optical axis of the beam projector obtained using the projector that has just been described, the line YY 'representing the intersection of this screen with a horizontal plane.
  • This figure shows a substantially horizontal half-cut C g to the left of the optical axis X'X of the headlamp, and a half-cut C d to the right of the optical axis X'X, inclined by approximately 15 ° relative to the horizontal and above the latter.
  • the passing beam thus comprises a first portion F I located below the horizontal Y'Y and a second portion F II located above the horizontal Y'Y and below the half-cut C d .
  • the present invention is intended to make the modification of the geometry of the light beam imposed by the change of direction of traffic by means substantially as simple to implement and as inexpensive as the holiday cache described in introduction, while retaining all the luminous flux emitted by the projector.
  • the present invention is based on the unexpected discovery that with a projector of the elliptical genre as just described, it is still possible to completely eliminate the annoying areas of the light beam during a reversal of the meaning while maintaining the photometric properties of the light beam required by legislation or regulation.
  • At least a first region I, through which the light rays corresponding to the part F I of the passing beam situated below the horizontal Y 'Y and at least a second region II through which light rays corresponding to the part F II of the passing beam located between the horizontal Y'Y and the half-cut C d located above the horizontal Y'Y pass.
  • the second region II may for example be determined by moving an opaque cover in front of the protective glass G, and observe on the screen E of Figure 3A the resulting effect in the light beam. For a given position, shape and dimension of this cover, the light beam on the screen E no longer has a part such as F II .
  • the opaque cover thus indicates the region II of the protective glass G corresponding to the beam portion F II .
  • the adapter device is constructed as a transparent and deflecting member of the light passing therethrough.
  • such a transparent element 10 and light deviation constituting the adaptation device comprises, when in place on the vehicle, a first substantially prismatic portion deviating the light downwards.
  • the adaptation device comprises two substantially flat faces 12 and 14 forming between them a low angle ⁇ , for example less than 5 degrees, the top of this angle pointing upwards when it is in place on the vehicle headlamp.
  • the substantially prismatic portion of the adaptation device 10 may consist of a prism itself, as shown in FIG. 4, or it may be constituted by a Fresnel prism, as has been 5.
  • a Fresnel prism at least one of the faces, for example the face 12, is discontinuous and formed of horizontal ridges 16.

  • the beam obtained can be further improved by means of the adaptation device 10 which has just been described. Indeed, we see in Figure 3B that the light beam has a place receiving both parts F I and F II ', this superposition may be detrimental to the homogeneity of the resulting beam.
  • the light rays passing through the adaptation device will undergo, in addition to the downward vertical deviation due to the prismatic part just described, a horizontal deflection whose amplitude will be fixed by the profile of the Vertical streaks 18.
  • the adaptation device 10 when the adaptation device 10 is put in place on the second region II of the projector glass, the part F II of the light beam is on the one hand deviated downwards, thanks to the substantially prismatic portion of the adapter device, and is further diverted and distributed horizontally, so as to occupy the position shown in F II ", as shown in Figure 5C.

  • the present invention also provides a laying template, such as those shown in FIGS. 11B for the headlamps whose lenses G R and G L are shown in Figures 9A and 9B.
  • FIGS. 11A and 11B show that each template 11 R and 11 L is adapted to the total shape of the protective glass of the crossing headlight for which it is intended, and that it delimits the second region protective glass, the one on which the adaptation device is to be affixed. It is then easy for the user to set up, without risk of error, the adaptation devices 10 R and 10 L to a change of direction of circulation.
  • the template simply delimits the region of the protective glass of the projector on which the adaptation device is to be arranged.
  • a template may consist of the indication of the distance X or Y of the outer edge of the ice to which the adaptation device is to be affixed.
  • the template may also consist of markers such as highlights, light ribs, silk screen printing, etc. on the projector glass.

It is thus also that the adaptation device can be made in the form of a flexible plastic film adhesive to be able to comply with the curvature of the protective glass of the projector to be equipped. The vertical and horizontal deflection characteristics of the device will then have been calculated to be optimal in such a non-planar configuration. Moreover, although the foregoing description is more particularly related to the case where a right-hand traffic beam must be adapted to suit left-hand traffic, those skilled in the art will immediately be able to make the adaptations making it possible to process the opposite case. .
