Lighting device of an aircraft, system, passenger service unit, method of operating a lighting device
Described are lighting devices of passenger aircraft. Also described are methods of operating the devices as well as lighting systems and passenger service units.
1. A lighting device for at least one passenger of an aircraft, comprising:
means for providing a light projection of an operator surface on a user-defined suitable body within an aircraft, wherein:
the operator surface is adapted for generating touch signals; and
the operator surface is performed by;
a beam forming module for adjusting the light beam geometrical properties and
a light forming module for adjusting the light optical properties;
wherein:
the light projection is formed as a continuous adaptable light projection, wherein:
a first sensor unit provides size and position information of the suitable body for a continuous adaption of the operator surface on the body;
a second sensor unit detects the generated touch signals corresponding to the position on the operator surface being touched; and
the generated information and the generated touch signals are transmitted to an operator system for achieving an operating response.
2. The lighting device according to claim 1 , wherein the continuous adaptable light projection is initiated by an activation signal and/or a starter signal.
3. The lighting device according to claim 1 , wherein the operator surface comprises a continuous adaptable illumination pattern.
4. The lighting device according to claim 1 , wherein the operator surface comprises a virtual touch panel.
5. The lighting device according to claim 1 , wherein the continuous adaptable light projection is formed as a projection of a holographic film.
6. The lighting device according to claim 1 , wherein the suitable body is formed by a passenger's hand.
7. The lighting device according to claim 1 , wherein the continuous adaptable light projection includes the operating of service unit devices and/or a cabin attended call.
8. The lighting device according to claim 1 , wherein a physical touch panel adjoins the virtual touch panel and is configured to generate a touch signal corresponding to the position being touched on the virtual touch panel.
9. A system of a lighting device according to claim 1 and an external unit wherein the operator system is remotely controllable by the external unit.
10. The system according to claim 9 wherein the operator system is adapted to communicate wirelessly with the external unit wherein a transmission technology between the operator system and the external unit is selected from the group of technologies consisting of Wifi, RFID, IR and Bluetooth technology.
11. A passenger service unit comprising a lighting device according to claim 1 .
12. A method of operating a lighting device, the method comprising the steps of:
providing a light projection of an operator surface on a suitable user-defined body within an aircraft, wherein the operator surface is adapted for generating touch signals;
performing the operator surface by a beam forming module for adjusting the light beam geometrical properties and by a light forming module for adjusting the light optical properties; wherein:
the light projection is formed as a continuous adaptable light projection, wherein
a first sensor unit provides size and position information of the suitable body for a continuous adaption of the operator surface on the body;
a second sensor unit detects the generated touch signals corresponding to the position on the operator surface being touched; and wherein
the generated information and the generated touch signals are transmitted to an operator system for achieving an operating response.
13. A software code means storable in an operator system and adapted to control operation of a lighting device in the operator system according to a method as claimed in claim 12 .
