- Two-zone luminous device for a motor vehicle and a lamp equipped with such a luminous device.
- the present invention relates to a two-zone light device for a motor vehicle, and a fire, in particular an anti-fog, provided with such a light device.
- Motor vehicle lights generally located at the rear of the vehicle, are light devices that include one or more light sources and an ice that shuts the fire.
- the light source emits light rays to form a light beam that is directed towards the ice to produce an illuminating surface that transmits light to the outside of the vehicle.
- the color of the illuminating surface is characteristic of the function or type of fire.
- a white illuminated surface indicates that the light is a reverse light, that an amber illuminated surface is a direction indicator, and that a red illuminated surface is a traffic light.
- rear position or a stop light the stop light being of a more intense brightness.
- the rear of a vehicle has a plurality of illuminating surfaces, each illuminating surface having a color specific to each function.
- the light source has a light intensity chosen with respect to the type of fire.
- Each of the illuminating surfaces being furthermore produced by at least one different light source, the number of light devices on the vehicle is multiplied.
- the light sources are, for example, light-emitting diodes. This large number of light sources has an impact on the cost of manufacturing the lamps, especially when the light sources are light-emitting diodes or laser diodes.
- the configuration and positioning of the illuminating surfaces may furthermore be limited, certain configurations of illuminating surfaces being difficult to obtain, since it is necessary to ensure that the light sources illuminate the corresponding illuminating surface without illuminating an illuminating surface intended for another function. .
- the invention therefore aims to obtain a light device configured to reduce the number of light sources on a vehicle and to provide new possibilities for layout and design of different lights.
- the invention relates to a dual-zone light device, particularly for a motor vehicle, comprising a transmission surface capable of transmitting light rays and at least one light source capable of emitting light rays to form a beam of light towards the transmission surface.
- the device is remarkable in that it further comprises distribution means configured to, on the one hand, distribute the light beam on a first dispersive zone of the transmission surface, and on the other hand, distribute the beam of light. light on a second dispersive zone of the transmission surface, the first dispersive zone being able to transmit the light beam with a first opening angle, and the second dispersive zone being able to transmit the light beam with a second angle of 'opening.
- the device uses the same light source (s) to illuminate two different dispersive zones. It is therefore avoided to have to multiply the number of light sources for different functions.
- each dispersive zone can fulfill a different function, the distribution means serving to direct the light beam of the light source towards one or the other of the zones.
- the device In addition, it is possible to easily arrange the illuminating surfaces and to create new fire designs thanks to the device, the positioning of the sources with respect to the illuminating surface that one wishes to obtain, which poses no problem.

- FIG. 2 schematically illustrating a view from above of the embodiment of FIG. 1,
- FIG. 3 schematically illustrating an ice-cream equipped with two zones
- FIG. 4 schematically illustrating the opening angle of the beams produced by the two zones
- Figures 1 and 2 show an embodiment of a motor vehicle light, for example a rear light, comprising a light device 1 according to the invention.
- the light device 1 comprises a light source 2 capable of emitting light rays to form a light beam and a transmission surface 3 capable of transmitting the light rays.
- the light source is of constant intensity, but it can also be of variable intensity depending on the desired fire function.
- the transmission surface 3 is for example arranged on the ice referenced 6 closing the fire.
- the transmission surface 3 is the inner face of the glass 6. It may also be a separate element of the glass 6, for example a transmission screen arranged in the fire in front of the ice 6.
- the light beam which comes from the light source 2 is intended to illuminate the transmission surface 3.
- the light source 2 is a laser source comprising, for example, a laser diode, emitting radiation whose wavelength is chosen to obtain the color corresponding to the function of the light on the 6.
- a wavelength conversion device for example a phosphor plate, is arranged in the path of the light beam to transform the wavelength of the laser radiation and thus obtain the desired color.
- the light source 2 may also comprise an optical device combining in one single beam several laser radiation, for example using optical fibers or devices taking advantage of the different polarizations of different laser sources or dichroic mirrors.
- the light source 2 is one or more electroluminescent diodes.
- the device 1 is provided with an optical system 5 configured to collimate the light rays coming from the source 2 in order to form the beam of light.
- the optical system 5 is for example a single collimation lens, and may also include a reflector.
- the light beam can project on the transmission face 3 a light trace which has a shape of dot, wider spot, or even an oblong mark.
- the transmission surface 3 is arranged on the glass 6 which closes the fire and comprises at least two dispersive zones, a first dispersive zone 10 capable of transmitting the beam of light with a first opening angle 12 and a second dispersive zone 1 1 capable of transmitting the light beam with a second opening angle 13.
- a first dispersive zone 10 capable of transmitting the beam of light with a first opening angle 12
- a second dispersive zone 1 1 capable of transmitting the light beam with a second opening angle 13.
- Each dispersive zone corresponds to a different function of the fire.
- the first zone 10 may correspond to a fog lamp, and the second zone 1 1 to a position light.
- the zones 10, 11 comprise, for example, dispersive patterns distributed on the transmission face 3.
- the dimensions of the dispersive patterns are chosen so as to fulfill the function of fire.
- Each function must meet the intensity and angle of projection of the light beam.
- the patterns are different on each zone so that the dispersed beam has a different opening angle after each zone.
- the dispersive units are preferably distributed uniformly over each of the two zones 10, 11 of the transmission surface 3.
- the pads 9 are substantially square, preferably with curved sides of a length 14 between 0.3 and 2mm.
- FIG. 6 shows the exit face of a pad 9 whose curvature causes the deviation of the light rays passing therethrough. The deflection is effected at an angle ⁇ relative to the axis 15 of the pad 9.
- the curvature of the pad 9 is chosen as a function of the angle ⁇ that is desired, and therefore of the first and second angles of desired opening.
- the pads of the first zone and the second zone have for example different radii of curvature.
- the device 1 comprises distribution means configured to, firstly, distribute the beam of light on the first dispersive zone 10 and / or the second dispersive zone 1 1 of the transmission surface 3.
- the distribution means can direct the light beam, or on the first dispersive zone 10 to obtain a first function of the fire, either on the second dispersive zone 1 1 to have a second function of the fire, or alternatively on the first 10 and on the second zone 1 1.
- the two zones 10, 11 are illuminated, the two functions being used simultaneously.
- the alternative distribution is performed at a frequency not perceptible by the eye.
- an observer has the illusion that both areas are illuminated at the same time.
- the first dispersive zone 10 transmits the light beam with a first aperture angle 12, and the second dispersive zone 11 transmits the light beam with a second aperture angle 13.
- Each aperture angle opening 12, 13 corresponds to a function of the fire.
- the first function is a fog lamp and the second function is a rear position lamp, the first opening angle 12 being smaller than the second opening angle 13.
- the light beam is more intense after the first dispersive zone 10 than after the second dispersive zone 1 1.
- the distribution means are scanning means 4 configured to ensure scanning by the light beam of the transmission surface 3.
- the scanning is performed at a sufficiently high speed so that the human eye does not perceive the movement of the light trace on the transmission surface 3, and observes a substantially constant and uniform illumination of the scanned portion of the lens 6.
- the scanning is performed on the area 10, 1 1 selected.
- simultaneous illumination of the two zones 10, 1 1 the scanning is performed on each zone one after the other, either in whole or in parts (for example by lines), in a iterative process.
- the scanning means 4 then have a sufficient scanning frequency to simultaneously scan each zone individually and pass from one zone to another without the human eye perceiving it.
- the transmission surface 3 may advantageously be configured to have a sufficient dispersion of the beam in case of malfunction of the scanning means 4. Indeed, if the scanning is interrupted, the laser beam is frozen in one direction. It is therefore necessary to ensure the safety of an observer, especially concerning his eyes, at least from a certain distance from the fire.
- the dispersion is sufficient to ensure this safety after about fifteen centimeters, for example.
- other alternative or complementary safety means may be provided in case of failures of the laser source or the scanning system which generated an eye hazard for fire watchers.
- the light beam coming from the light source 2 is, before striking the transmission surface 3, preferably returned by the scanning means 4 to a first mirror 7 which reflects it to a second mirror 8.
- the second mirror 8 reflects on turn the light beam to the transmission surface 3 of the ice 6 of the fire.
- the two mirrors 7, 8 serve to fold the optical path of the light beam to obtain a compact fire while allowing the light beam to scan the transmission surface 3 with a near normal incidence.
- FIG. 2 represents the luminous device 1 with the path of the light beam from the light source 2 to the mirror 6.
- the scanning means 4 are a mobile micro-mirror, enabling the transmission surface 3 to be scanned by reflection of the light beam in a first direction of the transmission surface 3, which is, for example horizontal.
- the micro-mirror is animated a periodic movement produced by an actuator (not shown). The movement of the micro-mirror is operated around an axis of rotation orthogonal to the first direction so that the light trace of the light beam sweeps the transmission surface 3 along said first direction.
- the scanning means 4 are also configured to scan the transmission surface 3 with the light beam in a second direction.
- the second direction is preferably substantially perpendicular to the first direction to produce a movement of the beam which moves easily on the transmission surface 3.
- the micro-mirror is also configured to scan the transmission surface 3 with the light beam in the second direction. In other words, it is the same micro-mirror which sweeps the transmission surface 3 with the light beam in both directions.
- the micromirror therefore follows another movement, for example rotation about a second axis of rotation perpendicular to the previous one.
- the micro-mirror allows the light trace of the light beam to scan both horizontally and vertically the transmission surface 3.
- an alternative embodiment is to use a second micro-mirror to scan the light beam in the second direction.
- the scanning means 4 are provided with two micromirrors arranged one after the other on the optical path of the beam, each having the function of scanning the light beam transmission surface 3 according to one of two directions.
- the micro-mirrors mentioned as scanning means are for example MEMS type (for "Micro-Electro-Mechanical Systems” or English electromechanical system).
- the invention is not limited to this scanning means and can use other kinds of scanning means, such as a series of mirrors arranged on a rotating element, the rotation of the element generating a scan of the surface transmission by the light beam.
- the distribution means are, for example, a micro-mirror matrix of the DMD (for "Digital Micromirror Device") type, which directs the light beam by reflection.
- the light beam is reflected in two directions, either towards the first dispersive zone or towards the second dispersive zone 11.
- Each micro-mirror can pivot between two fixed positions, a first position in which the incident light rays are reflected towards the first dispersive zone, and a second position in which the incident light rays are reflected towards the second dispersive zone 10, 1 1.
- the two fixed positions are oriented in the same way for all the micro-mirrors and form between them a characteristic angle of the matrix of micro-mirrors.
- this device can advantageously be used to display pictograms, which can in particular be dynamic.
- the distribution means are then configured to distribute the light beam on the transmission surface so as to show the pictogram (s).
