20110163697
The present application is based on and claims priority of Japanese patent application No. 2010-1976 filed on Jan. 7, 2010, the entire contents of which are hereby incorporated by reference.
1. Field of the Invention
The present invention relates to an illuminating device for illuminating a cabin of an aircraft using organic EL (organic electroluminescence; OLED).
2. Description of the Related Art
Recently, OLED illuminating devices utilizing OLED panels as light emitting modules are being used in practice.
OLED panels emit light through the whole planar area of the panels, and require only a small amount of energy for emitting light. Further, the panels can be formed with a light weight.
Japanese patent application laid-open publications No. 2009-48814 (patent document 1) and No. 2009-164022 (patent document 2) disclose OLED illuminating devices.
Further, Japanese patent application laid-open publication No. 2008-260391 (patent document 3) discloses applying the OLED for illuminating the interior of an automobile or other vehicles.
It is important for the various equipments disposed in an aircraft to have superior certainty of operation, and to have light weight.
It is indispensable that the illuminating device within a cabin of an aircraft has sufficient illuminance to ensure the safety of passengers while avoiding occurrence of firing and other dangers.
Moreover, the operation of the aircraft requires the illuminating device to have long life, light weight and energy-saving property.
The present invention aims at solving the problems of the prior art by providing a cabin illuminating device of an aircraft using OLED that satisfies the various demands described above.
In order to achieve the above-mentioned object, the present invention provides a cabin illuminating device of an aircraft, wherein an OLED illuminating panel is disposed in a direction parallel to an axis line of a fuselage on a ceiling within the cabin. Further, the cabin illuminating device can also have an OLED illuminating panel disposed in a direction parallel to an axis line of a fuselage on an upper portion of a window panel.
Moreover, the cabin illuminating device can include an OLED illuminating panel having a plurality of OLED illuminating panels disposed within a cabin of the aircraft divided into multiple zones, and a central control unit connected to the respective OLED illuminating panels via a signal line and a power line, wherein the central control unit is equipped with a function to adjust an illuminance and a color of the OLED illuminating panels of the respective zones, or a function to control the illumination pattern of the OLED illuminating panels of the respective zones.
Since the cabin illuminating device of an aircraft according to the present invention has OLED panels disposed on a ceiling or above window panels, the present invention enables to provide a light weight and power saving illuminating device.
The cabin of an aircraft, the whole area of which being denoted by reference number 1, has an aisle 12 formed on a floor 10 of a cabin which connects to a door 80. Bins 60 for storing carry on luggage for passengers seated in the center-section seats are installed on both sides of passenger service units (PSUs) 20. Window panels 40 supporting windows 42 are disposed on the side walls. Seats 50 are disposed at appropriate intervals on the floor 10, and passenger service units (PSUs) 20 are disposed above the seats 50 and a partition 70 for separating the cabin from a galley is disposed on a front side thereof.
Bins 62 for storing carry on luggage are also disposed above the window panels 40.
The cabin illuminating device of the aircraft according to the present invention provides an OLED illuminating device 100 disposed on ceiling panel 95 surface and between bins 62 arranged above the window panels 40 and bins 60 arranged above the seats 50 in the center-section of cabin 1. The OLED illuminating device 100 can also be disposed on the passenger service units (PSUs) 20 above the seats 50 in the center section of the cabin.
Since the OLED illuminating device 100 emits light from the whole surface of the panel, it has superior illumination efficiency. Further, since the device 100 has light weight, it is suitably adopted for illuminating the interior of the aircraft.
According to the present embodiment, the OLED illuminating device 100 is disposed in a direction parallel to the axis line of the fuselage.
Further, the illuminance of the device can be adjusted easily by cabin attendants.
According to the present embodiment, an OLED illuminating device 200 having a narrow width is disposed between an upper portion of the window panels 40 and a passenger service unit (PSU) 90.
The present embodiment enables efficient use of space, and is suitable for illuminating the cabin of an aircraft.
Further according to the present embodiment, the OLED illuminating device 200 is disposed in a direction parallel to the axis line of the fuselage. The illuminating device can either be a direct lighting or an indirect lighting.
Further, since the OLED illuminating panel can be designed to have a flat surface or a curved surface, it is suitably applied to the interior of the cabin of an aircraft having many curved surfaces.
The control system denoted as a whole by reference number 300 includes a central control unit 310, and OLED illuminating panels 200 disposed above window panels connected to the central control unit 310 via a power/signal line 320 and divided into multiple zones 410 and 420 within the cabin.
Similarly, OLED illuminating panels 100 disposed on a ceiling at multiple zones 510 and 520 within the cabin are also connected to the central control unit 310 via the power/signal line 320.
The central control unit 310 has a function to control the luminance of the OLED illuminating panels in the respective zones. Further, the central control unit 310 has a function to change the color of the OLED illuminating panels in the respective zones and to control the same.
Since the central control unit has the above-described functions, it becomes possible to control the illuminance and color of the illumination in the respective zones, and to provide a most appropriate lighting for the passengers.
Furthermore, the central control unit has a function to set up lighting patterns for the whole cabin of the aircraft or for the respective zones. Thus, it becomes possible to provide a most appropriate lighting for the passengers according to the status surrounding the aircraft or according to the time zone.
