Definitions
- the present invention relates generally to motor vehicle headlamps, and more particularly to a complementary headlamp capable of selectively generating two distinct types of beams, for example on the one hand a so-called turning bend beam, intended for illuminate the road taking into account the turns taken by the vehicle and on the other hand a different beam, for example of the fog type.
- headlamps intended to equip most high-end or medium-range vehicles, headlamps generating a cornering beam already exist; they conventionally comprise a reflector generating with a light source such as a filament lamp a so-called turning beam, this reflector being mounted so as to pivot about a generally vertical axis and displacement means being provided for controlling the angular position of this reflector to the position of the vehicle's steering wheel, for example.
- headlights which combine a cornering headlight and a fog light in the same housing.
- the document FR-A-2 626 625 describes an optical unit 5 comprising a single light source which cooperates on the one hand with a first reflector, fixed and of large size, to form an anti-fog beam, and on the other hand with a second reflector, rotating inside the first reflector, to generate a 0-type beam.
- Document FR-A-2 577 014 also discloses an optical unit similar to the previous one, in which the glass is designed to deflect the rays coming from the movable reflector and those coming from the fixed reflector differently.
- a true turning beam as it seems today widely accepted by the automotive industry, must have a lateral spread of approximately ⁇ 20 °, delimited in the upper part by a horizontal cut, and present in the axis has a maximum light of at least around 20 to 25 Lux at
- the bend beam defined above is distinguished from a conventional fog beam by a substantially lower spread and by a range, defined by a spot of central concentration, which is much greater.
- the present invention aims to improve the cornering headlights of the prior art, and in particular to take advantage of the characteristics of a cornering headlight to achieve on demand and separately, by 'simple, economical and easy to set up means industrially, another type of beam, such as a fixed fog beam, with regulatory photometry.
- the present invention aims to provide a projector in which the number of components used remains limited, with the advantage of a small footprint, great simplicity of assembly and a reasonable cost.
- the invention provides a motor vehicle headlamp, comprising a light source mounted in a reflector, and a lens, the reflector being mounted pivoting about a generally vertical axis and displacement means being provided for varying the angular position of the reflector, characterized in that the reflector is capable of occupying at least a first angular position in which the beam emitted by the latter passes through a first lens to generate a first type of beam, and a second angular position, fixed and distinct from the first angular position or positions, in which the emitted beam passes through a second lens, and in that the projector also includes optical means making it possible to generate, through said second lens, a fixed beam of photometry different from that of the beam generated through the first lens.
- Preferred, but not limiting, aspects of the projector according to the invention are as follows: - the first and second windows are located in the extension of one another.
- the first and second windows are made in one piece.
- the lens extends in front of the second lens, which then constitutes an intermediate screen between the reflector and the lens.
- the first glass is essentially smooth and its surface is oriented so as to attenuate the losses by reflection thereon.
- the beam generated by the single reflector is a cut-off beam spread in width.
- the fixed beam of different type is a fog-type beam.

- a bend / fog light which comprises a light source such as a halogen lamp comprising an axial filament 10, a beam-forming reflector 20, and a lens 40 having a first part 41 and a second part 42.
- the assembly is received in a suitable headlamp housing, not shown.
- the reflector 20 is capable, by itself, of generating a turning beam having the characteristics mentioned in the introduction.
- the person skilled in the art will be inspired for example by documents FR-A-2 536 503, FR-A -2 602 305, FR-A-2 609 148, FR-A-2 639 888, FR- A-2 664 677 all in the name of the Claimant. They describe surfaces capable of emitting a beam delimited by a generally horizontal upper cut, and for some also describe how to give such a cut beam the requested width.
- a reflector 20 is used based on a plurality of individual reflecting surfaces capable of generating each of the images of the filament which are all located below a cut, and preferably essentially aligned below and flush with this. cut, and which at the same time each ensure a homogeneous and controlled spreading of the images under said cut. More precisely, we start by defining one of the areas of the reflector (preferably its bottom area) according to the principle of the aforementioned documents, by adjusting its parameters, and mainly the shape of the horizontal generator and the high and low defocuses of the sections. vertical of the reflecting surface, depending on the size of the reflector and the photometry sought for the wide part of the beam.
- the adjacent zones on the left and on the right of the background zone, are defined with their own parameters (here again mainly the shape of the horizontal generator and the high and bottom of its vertical section), on the one hand as a function of the desired positioning of the light projected by these zones, and on the other hand and above all so that the reflecting surface of these adjacent zones intersects the reflecting surface of the bottom along a transition line which on the one hand extends from top to bottom between the upper and lower edges of the reflector, and on the other hand gives rise along this to a lateral deflection, by each of the reflecting surfaces adjacent, which is not constant, but which on the contrary varies regularly along this line.
- their own parameters here again mainly the shape of the horizontal generator and the high and bottom of its vertical section
- the construction of the reflector is continued by defining, in the same manner as above, a third zone adjacent to the second zone, etc.
- a reflector for a cornering headlight is thus produced in which different zones juxtaposed laterally can be configured so as to generate parts of different beams with great flexibility, to facilitate the modeling of the final beam, while obtaining a reflective surface without discontinuities.
- 'zero order which in a well known manner create optical anomalies, and obtaining a surface whose appearance, projector off, is that of a reflector with left and wide stripes, interesting from an aesthetic point of view.
- the part of the lens associated with the turning function as will be seen below can be entirely smooth, or contain only optically inactive style elements. This glass can therefore without inconvenience remain fixed, in contrast to the glass of certain turning headlights of the prior art.
- a reflector 20 having a short base focal distance is preferably used, so as to optimize, in given contours, the quantity of light recovered; its depth, width and height are preferably of the order of 20 mm x 60 mm x 30 mm, which allows, thanks to the design of the reflector described above, to reach a minimum of 20 lux in the axis (with a standard filament lamp type "Hl" or the like) while having an appropriate width.
- the reflector comprises in the present example five zones designed as described above, namely:
- a hole for the lamp such as a standard monofilament lamp of type "Hl”, “H2”, “H3”, “H7”, or the like.
- - bottom zone Z1 it has a horizontal generator capable of achieving a large horizontal spread of approximately -20 ° to + 20 °, so as to give the beam, with large images of the filament 10, the required width; its width in the axial horizontal plane is preferably between approximately 15 and 18 mm; - left and right intermediate zones: they are preferably symmetrical with respect to the axial vertical plane and capable of ensuring intermediate spreading advantageously ranging from about -12 ° to + 12 °, so as to increase the amount of light from both 'other from the axis of the road; their width in the axial horizontal plane is preferably between approximately 7 and 9 mm each; edge zones: they are preferably symmetrical with respect to the axial vertical plane and capable of ensuring a more reduced spread, varying progressively from ⁇ 7 ° at the level of the transition with the adjacent intermediate zone, to 0 ° at the level of the lateral edge of the reflector; in this way, with the smallest filament images, the light concentration in the axis is achieved, making it possible to reach
- the lateral spread provided by the different zones is all the more reduced as the zone is laterally distant from the optical axis.
- each of the beam parts has fuzzy lateral edges, which on the one hand ensures a homogeneous mixture of these different parts of beam in the overall beam, and on the other hand makes it possible to obtain an overall beam with blurred lateral edges, with a progressive illumination of the previously dark areas which is very advantageous in the context of a cornering headlight.
- the angular values given above are average values, the spread provided in reality varying gradually around these average values.
- the projector is intended to be mounted on the right side of the front of the vehicle.
- the reflector 20 can, in a first operating mode, occupy a variable angular position ⁇ l to the right, this angle being measured between a direction denoted AL, parallel to the longitudinal axis of the vehicle, and the optical axis AO of the reflector 20
- the value of the angle ⁇ l can for example vary between 10 ° and 40 °, being 40 ° when the steering wheel of the vehicle is turned to the maximum to the right and 10 ° when the steering wheel of the vehicle steers the vehicle straight or turned to the left, with intermediate angles depending on the amount of right turn taken by the vehicle.
- the angle ⁇ 1 remains fixed, and for example equal to 10 °, whatever the position of the steering wheel.
- the light beam passes through a first part 41 of the glass, which, as we have seen, can be smooth.
- the projector is designed to adopt a second mode of operation, in which the axis AO of the reflector 20 now forms with the axis AL a fixed angle ⁇ 2, for example 20 °, to the left. In this position, it is a second part 42 of the glass, distinct from the first, which is crossed by the beam from the reflector.
- the reflector 20 is pivotally mounted around a vertical axis preferably passing in the vicinity of the filament 10.
- the means of displacement of the reflector 20 may be entirely conventional , and will therefore not be described further.
- a headlamp according to the invention mounted on the left side of the front of the vehicle will include a reflector 20 capable of occupying in the first operating mode a position or an angular range ⁇ l to the left, and in the second operating mode an angular position ⁇ 2 fixed at 20 ° to the right.
- the beam coming from the reflector 20 crosses the part 41 of the glass 40, a part which is essentially smooth and whose geometry makes it possible to attenuate the losses by reflection thereon.
- the beam transmitted outside the headlamp is of bend type.
- the reflector 20 is oriented by said means of displacement to the position angular ⁇ 2 to cross part 42 of the ice.
- Part 42 of the glass therefore has optical arrangements, as will be described below with reference to the figures 3 and 4, firstly to increase the horizontal spread of this beam, secondly to dilute its concentration spot, and thirdly to generally straighten the beam, in order to form the fog beam of desired photometry, emitted in a direction average substantially parallel to the axis AL.
- FIG. 3 shows a first embodiment of part 42 of the crystal 40, where the external face of said part 42 forms with the mean plane of its internal face a prism intended to deflect the incident rays to the right by an angle for example 20 °, while its internal face is provided with vertical ridges 421 in order to dilute and spread the incident beam horizontally.
- FIG. 4 shows a second embodiment of the part 42 of the glass 40, where the distance between the external face of the glass 40 and the mean plane of its internal face is constant, the prismatic effect then being provided by the ridges vertical prismatics 422 which also make it possible to dilute and spread the incident beam horizontally.
- FIG. 5 represents a second embodiment of the invention, according to which the glass 42 is produced in the form of an intermediate screen, the smooth part 41 of the glass 42 extending, remaining smooth, in front of the intermediate screen (part 43).
- the angular position of the reflector 20 can be controlled, in the first operating mode of the headlight, to the position of the vehicle steering wheel, so as to support the trajectory of the vehicle when cornering.
- Part 41 of the glass is of course designed to cover the whole extent of this angular range.
- FIGS. 6 and 7 a bend / fog light is shown according to a third embodiment of the invention, which is characterized by the additional presence of a deflection mirror 30.
- the reflector 20 is capable of generating a so-called turning beam and mounted pivoting about a vertical axis preferably passing in the vicinity of the filament 10. Its angular position is here again controlled relative to the position of the steering wheel of the vehicle, so as to accompany the trajectory of the vehicle when cornering.
- the headlamp is intended to be mounted on the right side of the front of the vehicle, and the reflector 20 can adopt, in the first operating mode (cornering mode), any angular position ⁇ l for example between 6 and 35 ° to the right. Its rotation is adjusted between these values when the vehicle turns right, while its position remains 6 ° to the right, in this example, when the vehicle is in a straight line or turns left.
- the deflection mirror 30 is in this case a fixed plane mirror, inclined for example at 45 ° relative to the longitudinal axis AL of the vehicle.
- the crystal 40 is designed to extend on the one hand in front of the reflector 20, and on the other hand in front of the mirror 30.
- first part 41 preferably generally smooth or only provided optically inactive decorative elements, located so as to be traversed by • the beam emitted by the reflector 20 where it adopts the inclinations of 6 to 35 ° described above, and a second portion 42 having ridges 421 preferably vertical and located on its inner face, this second part being located in front of the deflection mirror 30.
- the parts 41 and 42 of the glass are made in one piece.
- the projector can adopt a first operating mode (FIG. 1) corresponding to a turning function.
- the reflector 20 adopts a position between the two extreme angular positions shown in this figure, as described above, and the part 41 of the glass is dimensioned and positioned so as to let the beam exit throughout the angular interval covered by the reflector 20.
- the second operating mode is illustrated in FIG. 2.
- the reflector 20 is tilted in the direction of the deflection mirror 30, and the latter returns the turning beam generated by said reflector 20, without alteration at this level, in direction of part 42 of the ice.
- the tilting of the reflector 20 can be carried out up to an angle of approximately 90 ° relative to the direction AL, the reflector 20 then being kept fixed in this position.
- the streaks 421 of this part have the object, as previously, on the one hand of increasing the horizontal spreading of this beam, for example up to values of the order of ⁇ 40 °, and on the other hand of dilute in this enlarged beam the spot of concentration existing in the original turning beam. In this way, a beam is obtained at the outlet from the part 42 of the glass which is perfectly suitable for constituting a fog beam.
- the lateral distance between the reflector 20 and the mirror 30, the size of the mirror 30 and the position of the transition between the parts 41 and 42 of the glass are chosen so that each of these two parts is affected only to the function considered, turn or fog.
- Figure 3 illustrates another embodiment of the present invention.
- the glass 40 is entirely smooth, while the deflection mirror, designated by the reference 130, is no longer a plane mirror but a mirror having a plurality of vertical stripes 131. These stripes have the role that had the streaks 421 of the ice in the embodiment of FIGS. 1 and 2, namely ensuring horizontal spreading, and dilution of the concentration spot, of the beam as it is delivered by the reflector 20.
- An advantageous characteristic of the invention in its various embodiments described above resides in that advantage is taken of the pivoting mounting of the reflector 20, and the displacement means thereof, used to perform the turning function, to effect another displacement of said reflector and, possibly in cooperation with a deflection mirror and with the striated part 42 of the crystal, to selectively generate another type of beam, in this case an anti-fog beam.
- the invention can be used to generate with a turning reflector turning reflector beams other than of the fog type.
- the invention is finally particularly advantageous in that it makes it possible to selectively generate two distinct types of beams with a single projector of reduced bulk. It thus offers specialized lighting possibilities, in particular in a confined environment under the hood of the vehicle.
