    专利说明:

    [0001] The invention relates generally to onboard lighting equipment on board aircraft and, more particularly, to outdoor lighting equipment for aircraft. As is known, the aircraft are equipped with a number of external lighting devices which are intended to be used either during flight phases or on the ground, for example during taxi phases or during parking. The lighting devices for aircraft therefore provide a signaling function and a lighting function. With regard to the lighting function, it is in particular to improve the visibility of the areas of runways and landing and tarmac.
    [0002] At night, during the landing, take-off, taxiway or taxiway phases, the lighting devices are used successively or simultaneously to enable the pilot to identify the space in which it must evolve at night.
    [0003] Furthermore, during parking or when driving, it is known to use lighting devices for example provided on the horizontal drift of aircraft, for commercial purposes, for example to emphasize or illuminate the logo of the airline. In view of the foregoing, the object of the invention is to propose an aircraft lighting device capable of providing complementary illumination, in particular enabling additional visual information to be delivered when the aircraft is parked, at night, or even when driving phases. The object of the invention is therefore, according to a first aspect, an external illumination light beam projection device for an aircraft, comprising a light source adapted to be mounted on the aircraft so as to project said beam onto a surface of outdoor lighting, and wherein the light source comprises a video image projector. Thus, through the use of a video image projector, it is therefore possible to significantly increase the number of information projected on the outdoor lighting surface. In a particularly advantageous embodiment, such a device makes it possible to implement a projection technology known as "video mapping" on the outer surface of the aircraft, in order to make its external appearance attractive or when marketing campaigns, for example to promote an airline. However, it may also be to project video images on other surfaces, especially on the ground. It may for example be to project on the ground additional information useful to the pilot, such as the alignment of the aircraft with respect to the runway, its speed ..., or ground personnel, for example to identify security zones. According to another characteristic of the projection device according to the invention, the light source further comprises a set of at least one power lighting lamp, said video image projector and said power lighting lamp being arranged in a common box. According to yet another characteristic, in the latter case, the device comprises a system for combining the luminous fluxes from the projector and said power lighting lamp to output a light beam from the projector or said lighting lamp. . For example, the power light source has a light emitting diode source.
    [0004] Preferably, the power lighting source comprises, alternatively, a laser diode lighting source. The invention also relates, according to a second aspect, to the use of a projection device as defined above for the projection of video images on the outer surface of an aircraft or on the ground, said image projector video being placed on at least one mounting zone selected from the empennage, the wing or the root of the wing, and the front leg of the landing gear. Other objects, features and advantages of the invention will become apparent on reading the following description, given solely by way of nonlimiting example, and with reference to the appended drawings, in which: FIG. 1 is a diagrammatic view of an aircraft equipped with one or more light beam projection devices according to the invention; and FIG. 2 is a block diagram of one embodiment of a light beam projection device according to the invention. Referring firstly to Figure 1 in which a commercial aircraft A is recognized in which are implanted one or more projection devices according to the invention. In the exemplary embodiment shown, it is to project lighting beams of light on the outer surface of an aircraft or on the ground. Of course, it is not beyond the scope of the invention when it comes to projecting outdoor lighting beams for any other type of aircraft. It will be noted however that the invention finds a particularly interesting application when the projection device is used at night when the aircraft is moving on the ground or is parked. As previously indicated, an aircraft, in this case an aircraft, is provided with a number of runway lighting or signaling devices to illuminate the areas of a runway or taxiway when phases of taxiing, landing and takeoff and further, provide a signaling function of the aircraft. The aircraft is here further provided with one or more external lighting beam projection devices including a video image projector.
    [0005] As can be seen, such a device can be provided on different zones Z1, Z2 and Z3 of the aircraft, in particular on the empennage, and more particularly on the horizontal empennage (zone Z1), on the wing, and more particularly under the wing or above the wing and in particular at the root of the wing (zone Z2), or on the front leg of the landing gear or in front of the front leg (zone Z3). Of course, such a device can be positioned on any other suitable mounting area, depending on the intended use.
    [0006] Indeed, such a device, which incorporates a video projector, is intended to project video images either on the outer surface of the aircraft or, generally, the aircraft or on the ground. Thus, when the projection device is mounted so as to project video images on the outer surface of the aircraft, it can advantageously be mounted either on the horizontal stabilizer (zone Z1) or on the wing (zone Z2). , being turned towards the outer surface of the aircraft. On the contrary, when it is a question of projecting video images on the ground, it will advantageously be possible to mount the projection device either under the wing (zone Z2) or on or in front of the landing gear front leg. Also, when the lighting surface on which a video image is projected is constituted by the outer surface of the aircraft, the projected information may be commercial information, for example for the implementation of marketing campaigns or a light beam for highlight and highlight the airline's logo, the name of the aircraft or certain areas of the aircraft's exterior surface such as access routes. When it comes to projecting information on the ground, it is preferably security information, for example to delimit zones that must not be crossed when the jet engines are running, or still useful information to the pilot during the evolution of the aircraft on the ground.
    [0007] Of course, it is not beyond the scope of the invention when information of other natures are projected and whatever the surface on which they are projected. It should nevertheless be noted that the use of a video projector is advantageous insofar as it makes it possible to implement a projection technique known as "video mapping" which makes it possible to project light or video images onto volumes. , by recreating large images on relief structures. Note that the projector projection device on board the aircraft can be constituted by a dedicated lighting device, that is to say, separate from conventional lighting systems equipping aircraft. However, to reduce the size, weight and costs, such a projection device is advantageously integrated with the lighting and signaling systems that traditionally equip the aircraft. FIG. 2 is an illustration of an exemplary implementation of an external lighting light beam projection device for an aircraft according to the invention, combining the use of an image projector. video and the use of power lighting lamps. The device visible in FIG. 2 therefore comprises a source 1 of power lighting, intended to provide the traditional lighting and signaling functions of the aircraft, a video projector 2 intended to ensure the projection of the video images, and a Combination system 3, combining the luminous fluxes from the power source 1 and the video projector 2. Such a flow combining system is for example based on the use of a system of prisms and filters. light polarizers so as to pass either the stream F 1 from the source 1 or the stream F2 from the video projector 2 and direct it through a lens L to a mirror 4 to output, at output, a light flux to an exterior lighting surface.
    [0008] Note that in the exemplary embodiment shown, the projector is a DLP (for "Digital Light Processing" type) projector, with a light emitting diode, and thus comprises a light emitting diode video lighting source 5 and as is conventional, a set of DLP filters red, green and blue, 6, 7 and 8. As is known, according to this technology, the light beam from the source 5 is returned by a flow combining system 9 to a set associating the filters 6, 7 and 8 and a DLP matrix (not shown) which alternately process each color to output the video stream F2. Of course, the video content may be stored on any appropriate means, for example on board the aircraft. It should be noted, however, that it is not beyond the scope of the invention when a video projector based on other technologies is used. It will thus be noted that it is also possible, alternatively, to use a video projector with LCD, DLP or DMD type technology using lamp, LED or laser light sources. In particular, in the embodiment of FIG. 2, the power lighting source 1 is based on the use of light-emitting diodes. It is also possible, alternatively, to use a laser diode light source. Of course, as indicated above, the embodiment of the embodiment of FIG. 2 is advantageous insofar as the projection device incorporates one or more sources of power lighting and a video projector. The assembly can be arranged in a common housing to be mounted on the aircraft.
