Description
Priority requirement
The present application claims priority from european patent application No.17183164.7 filed on 25/7/2017, the disclosure of which is incorporated by reference.
Technical Field
The present invention relates to a modular lighting device for vehicles, equipped with a primary lighting module and a plurality of (i.e. at least two) secondary lighting modules with dual rotation capability, in order to selectively generate a combined overall high beam and a combined low/low beam, both formed by at least partially superimposing the projection of the single light beam produced by each individual lighting module at a predetermined distance from the lighting device, providing better forward lighting and a smooth transition from the production of the low/low beam to the production of the high beam.
Background
In the prior art, lighting devices for vehicles comprising a plurality of individual lighting modules, some of which are provided with a rotating element, such as a rotating reflector, are known.
EP2902701 discloses a lighting device having a fixed light source consisting of LEDs and a rotating support having two opposite faces, one constituting an ae reflector and the other performing a second function, e.g. an aspect function; the stationary motor rotates the support relative to the stationary light source to selectively orient the two sides of the front side of the device toward the direction of motion of the vehicle.
WO2016083689 discloses a modular lighting device provided with a main lighting module, which is stationary; and has a plurality (e.g., three) of secondary lighting modules, each of which produces a light beam that can be sequentially rotated in elevation and azimuth about a horizontal and vertical axis, respectively, of each secondary lighting module to form an overall forward light beam of different shape.
Although the lighting device of WO2016083689 is satisfactory for obtaining a low/low beam of the desired shape, for example with the same device having an oblique cut-off facing to the right or left of the overall beam, it is not satisfactory if a high beam has to be generated. Furthermore, the transition from producing a low light/low beam to producing a high beam may cause discontinuities in the produced beam and may be annoying anyway to the driver of a vehicle equipped with such a lighting device.
Disclosure of Invention
It is an object of the present invention to provide a lighting device for a vehicle comprising at least a primary lighting module and a plurality of (e.g. at least two) secondary lighting modules, at least the secondary lighting modules having a rotation capability about two different axes arranged perpendicular to each other, which device is free from the drawbacks of the prior art, in particular designed to selectively generate a low/low beam forward beam and a high beam forward beam both having an optimal lighting performance, and which device is simple, compact, has a cost-effective construction and is highly reliable, and wherein the transition from the generation of low/low beam to the generation of high beam is smooth and gradual, does not provide lighting discontinuities and avoids annoying the transition from low/low beam to high beam for the driver of the vehicle.
Thus, according to the present invention, there is provided a lighting device for a vehicle, comprising: a housing having a front inlet opening arranged to face in use a forward direction of travel of the vehicle; a main lighting module arranged inside the housing facing the front inlet opening and at least two secondary lighting modules rotatably carried with respect to the housing and the main lighting module, each secondary lighting module being rotatable about a respective first axis of its own, the first axes being arranged parallel to each other and transverse to a horizontal plane in use, and being rotatable about at least a second axis arranged perpendicular to the first axes; the main lighting module is designed to selectively generate, when it is switched on, a first light beam for a low-beam function and a second light beam for a high-beam function, which form a first light projection and a second light projection, respectively, on a test screen placed in front of the lighting device; and the secondary lighting modules are designed to generate, when they are switched on, a third light beam forming a third light projection on the test screen, which may partially overlap the first light projection and/or the second light projection; the lighting device further comprises a control unit for selectively switching on/off the primary and secondary lighting modules and causing each secondary lighting module to rotate about a first or second axis; wherein the control unit is adapted to cause all third light projections to overlap each other on the test screen and to overlap the second light projection, substantially in the center of the second light projection.

Detailed Description
With reference to fig. 3 and 4, the reference numeral 1 generally designates a lighting device for a vehicle, in the non-limiting embodiment shown, only the vehicle headlamp assembly schematically illustrated from the front, components not necessary for describing the content of the invention being deleted for the sake of simplicity.
The lighting device 1 is designed to be mounted on an outer side 3 of a vehicle 2 (only schematically and only partially shown in fig. 3), facing a forward driving direction FD of the vehicle 4, indicated by an arrow in fig. 4.
The lighting device 1 comprises a substantially cup-shaped housing 4, only partially shown in fig. 3, the housing 4 being designed to be mounted on the vehicle 2 in a known manner. The casing 4 is made of synthetic plastic material by injection moulding and has a front inlet opening 5, which in use is opposite the vehicle 2 and faces the forward travelling direction FD of the vehicle 1; the front entrance opening 5 is closed by a transparent cover 6 (fig. 4), the transparent cover 6 usually being constituted by a simple lens, i.e. a transparent lens without optical function.
According to one aspect of the invention, the casing 4 carries, inside it, at least one primary lighting module 7 and at least two (preferably three or more, in the embodiment shown three) secondary (or auxiliary) lighting modules 8, arranged side by side and all located on the same side of the primary lighting module 7, opposite the outside 3 of the vehicle 2.
All lighting modules 7 and 8 are visible from the outside through a transparent cover 6 closing the front entrance opening 5.
Of course, the lighting device 1 may comprise more than one main lighting module 7, e.g. two lighting modules arranged side by side, e.g. at the outer side 3 of the vehicle 2.
The housing 4 is designed to be mounted on the vehicle 2 in a known manner, the front inlet opening 5 being arranged, in use, towards the forward driving direction FD; a primary lighting module 7 and at least two (three in the illustrated embodiment) secondary lighting modules 8 are arranged facing the inside of the housing 4 of the front inlet opening 5.
The primary lighting modules 7 are carried in a fixed but adjustable manner inside the respective housings 4 by means of articulated joints provided with adjusting screws, known and not shown for the sake of simplicity, while the secondary lighting modules 8 are carried inside the housings, rotatable with respect to the housings 4 themselves and to the primary lighting modules 7 about their own first axes, each indicated in figure 3 with a different reference number "a", "B" and "C".
The first axes A, B, C of the secondary lighting modules 8 are arranged parallel to each other and transverse to the optical axis OA containing the lighting modules 7, 8 (i.e. the axis along which the light they generate travels forwards) and transverse to the horizontal plane of the lighting device 1.
For the sake of simplicity, only one lighting module 8 is shown in more detail and on an enlarged scale in fig. 4, having an optical axis OA along which the resulting light beam (denoted LB in fig. 4) travels forwards.
All the rotating lighting modules 8 have the same structure and each comprise (as described in more detail in the parallel patent application EP16200369.3 filed in the name of the same applicant on day 11/23 of 2016 and incorporated herein by reference in its entirety) one or more light sources (for example, LEDs) carried by a printed circuit board 9, at least one reflector 10 and at least one first actuator 11, so that the reflector 10 of each lighting module 8 rotates about a first axis A, B, C (axis a in fig. 4) of each module 8 with respect to the printed circuit board 9 carrying the light sources and with respect to the main lighting module 7.
Because each secondary lighting module is equipped with an independent actuator 11, the secondary lighting modules 8 can rotate about their respective first axes A, B, C independently of each other; further, they may also rotate together or independently of each other about a second axis D (fig. 4) disposed substantially perpendicular to the first axis A, B, C. The second axis D may be a common axis for all lighting modules 8, or each module 8 may have its own axis D perpendicular to the respective axis A, B, C, the axes D of all modules 8 being parallel to each other. The rotation of the lighting modules 8 about the axis D is controlled by a second actuator 12, one for all modules 8, or one for each module 8.
The lighting device 1 further comprises a control unit 13 (fig. 4), for example arranged inside or outside the casing 4, designed to selectively rotate the secondary lighting module 8 by the same or different angles about the first axis A, B, C and about the second axis D, and to switch on/off the secondary lighting module 8 and the primary lighting module 7 independently of each other.
In particular, as mentioned above, the secondary lighting modules 8 are preferably independently controlled by the control unit 13 via the first actuator 11 and the second actuator 12, respectively.
According to a characteristic of the invention, the main lighting module 7 is designed to selectively generate, at its start, a first light beam DB configured for the low-light function (fig. 3) and a second light beam HB configured for the high-light function. This functionality may be obtained, for example, by providing the main lighting module 7 with two different light sources (e.g. LEDs) positioned in different ways.
The first light beam DB and the second light beam HB form a first light projection LP1 and a second light projection LP2, respectively, on the same standard test screen (fig. 5) placed 25m in front of the lighting device 1.
Likewise, the secondary lighting modules 8 are designed to generate, when they are switched on, a third light beam LB for each lighting module 8, which forms third light projections T1, T2 and T3 on the same standard test screen at 25m, which may partially overlap the first light projection LP1 and/or the second light projection LP 2.
The control unit 13 is adapted to selectively switch on/off the primary and secondary lighting modules 7, 8 and to rotate each secondary lighting module 8 about the first axis A, B, C or the second axis D.
According to a main aspect of the invention, the control unit 13 is also adapted to make all the third light projections T1-T3 overlap each other and the second light projections LP2 on the test screen, i.e. when the lighting device 1 is in the high-beam configuration, all overlap on the light projections generated by the light beam HB configured as a high beam, wherein the module 7 is switched to emit the light beam HB and the module 8 is switched on and rotated about all the axes A, B, C, D so as to be inclined with respect to the horizontal and vertical planes.
All light projections T1-T3 overlap one another for a major part (i.e. more than 60%) thereof, substantially in the center of the second light projection LP2, i.e. more or less symmetrically centered in the light projection LP2 with respect to the optical axis OA of the main illumination module 7, which in the schematic diagrams of fig. 5 and 6 coincides with the intersection between the two reference axes H (horizontal) and V (vertical) of the test screen.
In particular, the control unit 13 is configured to simultaneously surround the first axis A, B, C and the second axis D by simultaneously rotating at least one secondary (preferably all) lighting module 8 such that all third light projections T1-T3 overlap each other on the test screen and overlap the second light projection LP 2.
Furthermore, the control unit 13 is used to project a third light T by means of at least one or all of the secondary light modules 8(1,2,3)A pre-established trajectory TR through the optical axis OA of the primary lighting module 7 is depicted on the test screen to enable simultaneous rotation of at least one or all of the secondary lighting modules 8 about the first axis A, B, C and its second axis D.
According to a preferred embodiment, as shown in fig. 6, the trajectory TR is linear, i.e. it is described by a mathematical equation of a straight line.
According to another preferred embodiment, not shown for simplicity, the trajectory TR is mathematically represented by a polynomial function of third order.
It was surprisingly found that these two specifically chosen trajectories ensure a smooth and fast transition of the entire lighting device 1 from the low light/low light configuration to the high light configuration, while not causing any annoyance to the driver of the vehicle.
According to another characteristic of the invention, the control unit 13 is intended to superimpose, as described above, all the third light projections T1-T3 on the test screen, overlapping each other and overlapping the second light projections LP2, substantially in the centre of the second light projections LP2, in such a way that the projections T1-T3 almost completely overlap each other (i.e. more than 60% of their amplitude), but at the same time are arranged laterally offset from each other; such a feature is obtained by rotating the second lighting module 8 around the first axis A, B, C such that the third light beam LB impinges the test screen with a rotation of a few degrees with respect to each other.
According to another feature of the invention, the lighting device 1 is configured such that all third light projections T1-T3 are always inscribed within the second light projection LP2 when the lighting device 1 is in the high-beam configuration, wherein the lighting module 7 is switched on to generate the light beam HB and the lighting module 8 is rotated such that its light beam LB overlaps with the second light projection LP 2.
In this way, the illumination performance of the high beam function of the second light beam HB is surprisingly greatly improved, especially over long distances.
As previously mentioned, the secondary lighting modules 8 are arranged side by side and on the side of the primary lighting module 7 opposite the first lateral end 14 of the housing 4, the housing 4 being designed to be mounted on the outside 3 of the vehicle 2 and to receive the primary lighting module 7.
In use, the vehicle 2 is provided with a pair of supplementary lighting devices 1 as described above, shaped as mirror-symmetrical and arranged on opposite outer sides of the vehicle 2.
It has to be noted finally that, according to the light pattern configuration shown in fig. 5 and 6, the control unit 13 is configured to have, in the high-beam configuration of the lighting device 1, light projections T1-T3, which light projections T1-T3 are almost entirely contained only within the light projection LP2 and are therefore arranged substantially outside the light projection LP1 (i.e. not contained in the light projection LP1), the light projection LP1 also being able to remain in the high-beam configuration, since in this case the lighting module 7 can switch on in such a way that it emits light beams DB and HB simultaneously.
In particular, the light projections T1-T3 are substantially aligned directly above the cut-off line 15 (FIG. 5) of the light projection LP 1.
From the above description, with reference to fig. 1 and 2 for comparison, in which the light patterns that can be obtained on a test screen with a lighting device of the prior art are shown, it is evident that even in a lighting device having substantially the same overall structure as the lighting device 1, the advantageous configuration of the light patterns as described herein is never obtained: in fact, according to the prior art, the light projections T1-T3 of the secondary light-emitting modules 8 are always aligned substantially below the cut-off line 15 of the light projection LP1 in both the high-beam configuration (fig. 2) and the low-beam/low-beam configuration (fig. 1) of the light-emitting device.
Thus accomplishing all the objects of the present invention.
