Description

Title of the invention: Luminous device for motor vehicle The present invention relates to a luminous device for motor vehicle.

It finds a particular but non-limiting application in fog lights.

A light device such as a fog light, known to those skilled in the art, comprises a housing closed by a closing glass, a mask, at least one light source, a light source support, and a lens . The mask holds the lens in place. The mask also makes it possible to give a style effect to the light device. It thus depends on the type of motor vehicle on which the light device is mounted. The housing includes fixing lugs which must be adapted according to the type of motor vehicle on which the light device is to be mounted. The assembly of the light device is done by mounting in the housing the parts in the following order: the light source support with said at least one light source, the lens, the mask and finally the closing glass to close the housing.

A disadvantage of this state of the prior art is that because of the housing which is specific to the type of motor vehicle on which the light device will be mounted, the assembly of the light device requires specific tools (assembly line , machine), corresponding to a given customer reference, for mounting the light source support, said at least one light source, the lens, the mask and the closing glass on said housing. Thus, for each new box corresponding to a new given customer reference, it is necessary to change tools to mount all the other parts of the light device in the box. Thus, as soon as the assembly of the parts of the light device begins, a specific tool must be used.

In this context, the present invention aims to provide a light device for a motor vehicle which overcomes the drawback mentioned.

To this end, the invention provides a light device for a motor vehicle, characterized in that said light device comprises:

b. a second housing which cooperates with said first housing,

vs. a glass for closing said second case.

Thus, as will be seen in detail later, the fact of having a first housing and a second housing, allows to have a light module integrated in the light device which can be standard for all motor vehicles on which the light device is mounted. A standard assembly line is used to assemble the parts of the light module. The second housing and the glass, for their part, must be adapted to the motor vehicle on which the light device is fixed.

According to a nonlimiting embodiment, said light module further comprises a holding plate to hold said optical element.

According to a non-limiting embodiment, said optical element is a lens.

According to a non-limiting embodiment, said light module further comprises a mask configured to be disposed between said optical element (13) and said second housing.

There is also proposed a light module of a light device for a motor vehicle comprising:

Identical elements, by structure or by function, appearing in different figures retain, unless otherwise specified, the same references.

The light device 1 for a motor vehicle according to the invention is described with reference to Figures 1 to 15. By motor vehicle is meant any type of motor vehicle. In a nonlimiting embodiment, the light device 1 is a front or rear fog light. In a nonlimiting variant, the fog light is separated from the headlight of the motor vehicle which performs a lighting function. A fog light generates a light beam (not shown) which includes a cut-off.

As illustrated in the exploded view of FIG. 2, the light device 1 comprises:

at. a light module 10 comprising:

i. at least one light source 11 configured to emit light rays (not shown), ii. a light source support 12, iii. an optical element 13 configured to cooperate with light rays emitted by said at least one light source 11, iv. a first housing 14 in which said at least one light source 11, said light source support 12 and said optical element 13 are arranged,

b. a second housing 15 which cooperates with said first housing,

vs. a closing glass 16 of said second housing.

In a non-limiting embodiment, the light module 10 further comprises a seal 17. In a non-limiting embodiment, the light module 10 further comprises a retaining plate 18. In a non-limiting embodiment , the light module 10 further comprises an adjustment screw 19. In a nonlimiting embodiment, the light device 1 also comprises a mask 20. These various elements are described in detail below.

The elements of the light module 10 described below are independent of the type of motor vehicle on which the light device 1 is mounted. They do not need to be adapted to a particular type of motor vehicle. They can thus be used in a standardized manner.

Said at least one light source 11 is particularly illustrated in Figures 3a and 3b. In a nonlimiting embodiment, said at least one light source 11 is a semiconductor light source. In a nonlimiting embodiment, the semiconductor light source is part of a light emitting diode. By light-emitting diode is meant any type of light-emitting diode, whether in non-limiting examples of LEDs (“Light Emitting Diode”), OLEDs (“organic LEDs”), AMOLEDs (Active-Matrix-Organic LEDs), or EOLED (Elexible OLED).

Said at least one light source 11 is configured to emit light rays which cooperate with the optical element 13 described below to generate a light beam. Said light beam makes it possible to perform the optical function of a fog light in the non-limiting example taken. In a nonlimiting embodiment, the light module 10 comprises a single light source 11. In another nonlimiting embodiment, the light module 10 comprises a plurality of light sources 11. In the nonlimiting example illustrated on Figures 3a and 3b, it comprises two light sources 11.

In a non-limiting embodiment illustrated in Figure 3b, said at least one light source 11 is connected to a printed circuit board 21, otherwise called PCBA card and known by the acronym "Printed Circuit" Board Assembly ”. This PCBA card comprises electronic components such as, in a nonlimiting example, a control device (not illustrated) of said at least one light source 11, otherwise called “driver” in English. In a nonlimiting embodiment, said at least one light source 11 is connected to the PCBA card by a bridge 110 called in English "wire bonding". In a nonlimiting embodiment, said at least one light source 11 is disposed on the light source support 12 described below. In a nonlimiting example, it is glued to it.

The light source support 12 is illustrated in particular in Figures 3a and 3b. In a non-limiting embodiment, the light source support 12 is a heat sink, otherwise called a radiator, which allows the heat generated by said at least one light source 11 to be removed. In a non-embodiment limiting, the light source support 12 is made of aluminum. It is a light material and dissipates heat well. In a nonlimiting embodiment, the light source support 12 comprises a base 120 and two fins 121 arranged perpendicular to said base 120. In a nonlimiting embodiment illustrated in FIG. 3b, the PCBA card extends over a plane parallel to the base 120. This arrangement simplifies the connection by bridging with the light sources 11.

The optical element 13 is illustrated in particular in Figures 6 and 7. It is arranged opposite the light source 11 as illustrated in Figure 7. The optical element 13 is configured to cooperate with the light rays emitted by said at least one light source 11 so as to generate a light beam. In a nonlimiting embodiment, the optical element 13 is a lens. In a nonlimiting embodiment, the optical element 13 is held in position by the holding plate

18. To this end, as illustrated in FIG. 6, in a nonlimiting embodiment, the optical element 13 comprises two tabs 130 each with a pivot counter-support 131 configured to cooperate each with a bearing 180 of the holding plate 18 described below. This allows rotation of the optical element 13 around a Y axis.

In a nonlimiting embodiment, a primary orientation of the optical element 13 is defined by means of the adjusting screw 19. The primary orientation is along an axis Z around an axis Y. At this Indeed, in a nonlimiting embodiment, one of the lugs 130 of the optical element 13 comprises a notched part 132 to cooperate with the adjusting screw 19. Furthermore, in a nonlimiting embodiment, this lug 130 is more as long as the other tab 130 so as to allow cooperation with the adjusting screw 19 described below. The optical element 13 pivots by virtue of its pivot counter-supports 131 around the axis Y defined by the bearings 180 of the holding plate 18. Thus, the optical element 13 can be rotated via the adjusting screw 19 described below while said at least one light source 11 remains stationary. The cut-off of the light beam that the optical element 13 generates can thus be adjusted more or less above the horizon defined by the Y axis.

The first housing 14 is illustrated in particular in Figure 4. It is otherwise called rear cover or rear housing. In a nonlimiting embodiment, the first housing 14 comprises two pivots 140 on which the optical element 13 can rest and around which it can rotate. The two pivots 140 define an axis of rotation of the optical element 13, which is the Y axis. In a nonlimiting embodiment, the first housing 14 also comprises an insertion part 148 for the adjusting screw

19. Thanks to the adjusting screw 19 described below and to the two pivots 140, it is possible to rotate the optical element 13 along the axis Z around the axis Y so as to orient the light beam which it generates . Thus, this allows an angular adjustment of the positioning of the cut of the light beam generated by the optical element 13 in height, in other words vertically with respect to the axis Y.

In nonlimiting embodiments, the first housing 14 further comprises

at. a housing 141 in which the base 120 of the light source support 12 can be housed,

b. a support flange 142 on which a gasket 17 described below can be positioned,

vs. a wall 143 which extends perpendicular to the support flange 142 and configured to surround the retaining plate 18,

d. four fixing holes 144 into which fixing lugs 181 of the holding plate 18 can be inserted. The fixing holes 144 are arranged in the wall 143.

In a non-limiting embodiment, the first housing 14 is configured to be assembled with said second housing 15 via a bayonet system. The bayonet system can be standardized so that the assembly between the first housing 14 and the second housing 15 can be standardized. To this end, in a nonlimiting embodiment, the first housing 14 comprises at least three lugs 145 configured to cooperate each with a notch 155 of the second housing 15 described below. This allows assembly by bayonet. The use of three lugs 145 makes it possible to define a plane, which makes it possible to give a horizontal reference for the optical element 13. In the nonlimiting example illustrated, the first housing 14 comprises four lugs 145 arranged on the wall 143 and each adjacent to a fixing orifice 144. The lugs 145 are configured to fit into the notches 155, and to exceed the material thickness of the flange 153 of the second housing 15. After the rotation of the first housing 14, the lugs 145 will rest on the flange 153 of the second housing 15.

In a non-limiting embodiment, the first housing 14 further comprises a flexible tongue 146 for locking with the second housing 15. In a non-limiting embodiment, the flexible tongue 146 is a piece made of material. In another non-limiting embodiment, the flexible tongue 146 is a molded part. The flexible tongue 146 forms a non-return system. It thus serves as anti-rotation for the first housing 14. The flexible tab 146 is in fact configured for:

at. insert into a notch 1560 (illustrated in Figure 11) of a mechanical stop 156 of the second housing 15. Upon insertion, it is armed;

b. after the rotation of the first housing 14, relax and abut against the mechanical stop 156 (illustrated in FIG. 11) of the second housing 15 so as to lock the first housing 14 with the second housing 15.

Thus, thanks to the flexible tongue 146 and the mechanical stop 156, the light module 10 does not rotate on itself when the light device 1 is in operation.

In a nonlimiting embodiment, the first housing 14 further comprises a connector part 147 configured to receive a connector of the motor vehicle for supplying the PCB A and said at least one light source 11.

The first housing 14 can be used for any type of motor vehicle. It is a standard element of the light device 1, which integrates the other standard elements 11, 12, and 21 as illustrated in FIG. 5b, and 13, 17, 18, 19 as illustrated in FIGS. 9 and 10 .

The seal 17 is particularly illustrated in particular in Figure 10. It is disposed between the first housing 14 and the second housing 15. The first housing 14 and the second housing 15 are connected by said seal 17. In one embodiment nonlimiting, it is configured to rest on the support flange 142 of the first housing 14. In a nonlimiting embodiment, the seal 17 is an O-ring. It provides a good seal between the first housing 14 and the second housing 15. In a nonlimiting example, the seal 17 is bonded to the first housing 14, in particular on its support flange 142. In another example not limitative, the seal 17 can be injected.

The holding plate 18 is particularly illustrated in Figures 8 to 10. It is called "bracket" in English. In a nonlimiting embodiment, it is an O-ring. In a nonlimiting embodiment, the retaining plate 18 comprises two bearings 180 configured each to cooperate with a pivot counter-support 131 of the optical element 13. The retaining plate 18 thus maintains the optical element 13 on the axis of rotation of said optical element 13, namely the Y axis. In a nonlimiting embodiment, the retaining plate 18 also comprises fixing lugs 181. In a nonlimiting example, it comprises two fixing lugs 181 on each side of the bearings 180, namely four in total. These fixing lugs 181 are configured to cooperate with the fixing orifices 144 of the first housing 14. Thus, the retaining plate 18 is fixed to the first housing 14 by means of these four lugs 181. It will be noted that the retaining plate 18 is independent of the mask 20 described below, namely it is separated from the mask 20.

The adjusting screw 19 is illustrated in particular in FIG. 6. The adjusting screw 19 is a worm. She understands :

at. a head 190 making it possible to manually adjust the primary orientation of the optical element 13 by turning said head 190,

b. a threaded rod 191 configured to cooperate with the notched part 132 of the tab 130 of the optical element 13 so as to set the optical element 13 in motion when the head 190 rotates.

The primary orientation is defined along the Z axis and around the Y axis. A rotational movement around the Y axis can thus be applied to the optical element 13. The adjusting screw 19 is arranged perpendicular to the tab 130 comprising the notched part 132 of the optical element 13. The adjusting screw 19 is configured to be inserted in the insertion part 148 of the first housing 14. It thus forms part of the light module

10. It can be used for any type of motor vehicle. Its arrangement does not depend on the type of motor vehicle on which the light device 1 is mounted.

The second housing 15 is particularly illustrated in Figures 11 and 12. It is otherwise called the front cover or front housing. It’s an open case. The second housing 15 is configured to be in connection with the first housing 14 via the seal 17. Thus, as illustrated in FIG. 12, its flange 153 will rest on the flange 142 of the first housing 14 via the seal 17 when the first housing 14 is assembled with the second housing 15. In nonlimiting embodiments, the second housing 15 comprises:

at. a wall 150,

b. a flange 153 perpendicular to the wall 150,

vs. an opening 154 through which the first housing 14 can pass. The opening 154 is surrounded by the flange 153. In a nonlimiting embodiment, the wall 150 is of variable height.

The second housing 15 depends on the type of motor vehicle on which the light device 1 is mounted. In a nonlimiting embodiment, the second housing 15 comprises at least one fixing point 151 on the motor vehicle. These fixing points 151 depend on the corresponding fixing means of the housing of the motor vehicle. The second housing 15 is therefore referenced relative to the type of motor vehicle on which it is to be mounted. In a nonlimiting example illustrated in FIG. 11, the second housing 15 comprises two fixing points 151. In a nonlimiting embodiment, they extend on either side of the wall 150 and perpendicular to said wall 150 In a nonlimiting embodiment illustrated, they include an orifice 151a for the insertion of a fixing screw (not illustrated). It will be noted that the wall 140 of the first housing 14 fits into the flange 153 of the second housing 15 as illustrated in FIG. 12.

In a nonlimiting embodiment illustrated in Figure 11, the second housing 15 comprises at least one slide 152 to hold the mask 20 in position. In a nonlimiting example illustrated in FIG. 11, the second housing 15 comprises two slides 152. They originate on the flange 153 and are perpendicular to said flange 153. Furthermore, they are supported along the wall 150. These slides 152 are configured to receive legs 202 of the mask

20.

In a nonlimiting embodiment, the second housing 15 comprises at least three notches 155 configured to cooperate each with a lug 145 of the first housing 14. This allows assembly by bayonet. In the nonlimiting example illustrated, it comprises four notches 155 arranged on the flange 153. In a nonlimiting embodiment, the notches 155 include a bevelled part 1550 which makes it possible to accompany the movement of the pins 145 of the first housing 14 during the rotation of said first housing 14.

In a nonlimiting embodiment, the second housing 15 further comprises a mechanical stop 156 configured to retain the flexible tab 146 of the first housing 14 for locking with the first housing 14. The mechanical stop 156 includes a notch 1560 in which the flexible tongue 146 can be inserted at the same time as the lugs 145 which are inserted in the notches 155. As illustrated in FIG. 12, this mechanical stop 156 is blocked between a lug 145 of the first housing 14 and the flexible tongue 146 after the rotation of the first housing 14 which prevents rotation in the opposite direction of the first housing 14 and consequently an unlocking of the first housing 14 relative to the second housing 15. The mechanical stop 156 is dimensioned so as to have a precise rotation of the first housing 14 relative to the second housing 15. The mechanical stop 156 defines a secondary orientation of the optical element 13 around the axis X. This allows a r angular adjustment of the positioning of the optical element 13 with respect to the X axis so that the cut-off of the light beam that it generates is horizontal with respect to the X axis. The mechanical stop 156 thus gives a reference to horizontality relative to the X axis for cutting the light beam.

The mask 20 is particularly illustrated in Figures 13 and 14. The mask 20 is disposed between the optical element 13 and the second housing 15. Thus, it is arranged on a separate part from that (the first housing 14) on which the retaining plate 18 is arranged. It comprises a wall 200 of variable height to adapt to the wall of variable height of the second housing 15. It is configured to fit into the wall 150 of the second housing 15 such that 'illustrated in Figure 14. In a non-limiting embodiment, it comprises at least one tab 202 configured to be inserted in a slide 152 of the second housing 15. In a non-limiting variant illustrated, it comprises two tabs 202 They are arranged opposite each other. One leg 202 is longer than the other. In a nonlimiting embodiment, the mask 20 further comprises an orifice 203 configured to receive a positioning point 160 of the closing glass 16. It will be noted that the mask 20 does not hold the optical element 13, but it is the holding plate 18 which does so. There is no contact between the mask 20 and the optical element 13. The mask 20 is an aesthetic covering for the light device 1. It makes it possible to give a style effect to the light device 1. In nonlimiting examples, it can have a grainy, black aluminum appearance etc. Thus, the characteristics of the mask 20 depend on the type of motor vehicle on which the light device 1 is mounted.

The closing glass 16 is illustrated in particular in FIGS. 1 and 15. The closing glass 16 is configured to close the second housing 15. As illustrated in FIG. 15, it includes a positioning point 160 for positioning the closing glass 16 in the mask 20 and in the second housing 15. This positioning point 160 is configured to be inserted in the orifice 203 of the mask 20 provided for this purpose. The closing glass 16 further comprises an edge 161 which comes into contact with the seal 17 when it is positioned on the second housing 15. This thus ensures a seal by joint contact. The closing glass 16 with the gasket 17 makes it possible to seal the light device 1. The closing glass 16 is visible from the outside. Consequently, it depends on the type of motor vehicle on which the light device 1 is mounted. The closing glass 16 is positioned in an inclined manner to adapt to the variable height of the wall 150 of the second housing 15. It is thus a function of the type of motor vehicle on which the light device 1 is mounted. It will be noted that the diameter of the second housing 15, of the mask 20 and of the closing glass 16 depend on the type of motor vehicle on which the light device 1 is mounted.

In a nonlimiting embodiment, the assembly of the light device 1 is as follows. After its manufacture, in a first step, the light support 12 is overmolded or assembled in the first housing 14 as illustrated in FIG. 5a. In a second step, the light source 11 is arranged on the light support 12, as illustrated in FIG. 5a also. In a third step, the PCBA card is mounted in the first housing 14 and it is connected to the light source 11 by bridging, as illustrated in FIG. 5b. In a fourth step, the adjusting screw 19 is inserted into the insertion part 148 of the first housing 14 provided for this purpose, as illustrated in FIG. 7. In a fifth step, the optical element 13 is mounted in the first housing 14 and disposed opposite the light source 11, as illustrated in FIG. 7 also. In a sixth step, the retaining plate 18 is positioned on the optical element 13 so as to hold it in position, as illustrated in FIG. 9. In a seventh step, the seal 17 is positioned on the flange 142 of the first housing 14, as illustrated in FIG. 10.

The light module 10 is thus mounted. All the parts of the light module 10 were thus pre-assembled together before assembly:

at. the light module 10 in the second housing 15,

b. of the mask 20 in the second housing 15, and

vs. closing glass 16 to close the second housing 15.

This light module 10 can be used for any type of motor vehicle. It is a standard product. The assembly line used for assembling the light module 10 can thus be a standardized chain. In an eighth step, the light module 10 is positioned in the second housing 15, as illustrated in FIG. 12. In a ninth step, the light module 10 is held in position by virtue of the bayonet system which locks the first housing 14 with the second housing 15. The bayonet locking being standardized as described above, the mounting of the light module 10 on the second housing 15 via the first housing 14 can thus be standardized. In a tenth step, the mask 20 is positioned in the second housing 15 above the light module 10, as illustrated in FIG. 14. Finally, in an eleventh step, the closing glass 16 is positioned on the mask 20 to close the second housing 15, as illustrated in FIG. 1. The mask 20 is sandwiched between the closing glass 16 and the second housing 15. There is no mechanical contact between the mask 20 and the first housing 14.

The light device 10 is thus assembled and can be mounted on the motor vehicle via the fixing lugs 151 of the second housing 15. A specific assembly line is thus used only for steps ten and eleven, and depends on the references of the second box 15, namely fixing lugs 151 which can be modified as a function of the box (not illustrated) of the motor vehicle, otherwise called customer box, on which the light device 1 is mounted.

Of course, the description of the invention is not limited to the application and to the embodiments described above. Thus, in another nonlimiting embodiment, the light device 1 is a headlight configured to perform a lighting function. Thus, in another nonlimiting embodiment, the light device 1 is a signaling light to perform a signaling function. Thus, in another nonlimiting embodiment, the mask 20 can be clipped with the second housing 15, glued to the second housing 15. Thus, in another nonlimiting embodiment, the light source 11 is mounted directly on the PCBA card. In this case, there is no second step as described during the assembly of the light device 1.

Thus, the invention described has in particular the following advantages:

at. by replacing a single box of the prior art with two boxes and 15, it makes it possible to have a standard light module 10 which can be used for several types of motor vehicle,

b. it replaces:

i. a specific assembly of all the parts (light source, light source support, lens, mask, closing glass) of a light device in a housing specific to the state of the prior art, and ii. a specific mounting of the specific housing on a motor vehicle of a given type, by:

iii. a standard assembly of several parts (light source 11, light source support 12, seal 17, retaining plate 18, adjusting screw 19, PCB A) of the light device 1 on a standard box (the first box 14) , and iv. a specific assembly only of two parts (mask 20, closing glass 16) and a specific assembly of a specific housing (the second housing 15) on a motor vehicle of a given type,

vs. it makes it possible to reduce the number of parts of the light device which are specific to a type of motor vehicle and therefore to:
