Abstract

A data communication apparatus comprising includes multiple white light emitting diodes or other sources of light which generate environmental lighting for a user of the data communication apparatus. The data communication apparatus also includes a data transmitting device positioned adjacent the white light emitting diodes, the data transmitting device configured to wirelessly transmit data signals to electronic devices used by the user. The data communication apparatus can also include a data receiving device for receiving wirelessly transmitted data signals from the electronic devices used by the user. The data communication device can be used, for example, in an aircraft cabin lighting system.

Claims

1. An aircraft cabin communications system comprising:

a plurality of data communication devices positioned throughout a passenger cabin of an aircraft, each of the plurality of data communication devices comprising;

a source of white light which generates environmental lighting for a corresponding passenger of the aircraft; and

a data transmitting device positioned adjacent the source of white light,

the data transmitting device configured to wirelessly transmit data signals to electronic devices used by the corresponding passenger; and

a data bus coupled to each of the plurality of data communication devices and carrying data signals for wireless transmission to the electronic devices used by corresponding passengers, wherein the data communication devices are disposed within overhead lighting panels.

2. The aircraft cabin communications system of claim 1, wherein each of the plurality of data communication devices further comprises a housing, wherein the source of while light and the data transmitting device of each data communication device are positioned inside the housing.

3. The aircraft cabin communications system of claim 2, wherein for each of the plurality of data communication devices, the housing is a light bulb housing.

4. The aircraft cabin communications system of claim 2, wherein the data transmitting device of each data communication device is an infrared transmitter.

5. The aircraft cabin communications system of claim 2, wherein the data transmitting device of each data communication device is an ultraviolet light transmitter.

6. The aircraft cabin communications system of claim 2, wherein the data transmitting device of each data communication device is an electromagnetic wave transmitter.

7. The aircraft cabin communications system of claim 6, wherein the data transmitting device of each data communication device is a radio frequency transmitter.

8. The aircraft cabin communications system of claim 2, wherein each data communication device further comprises a data receiving device positioned inside the housing adjacent the source of white light and the data transmitting device, the data receiving device configured to receive wirelessly transmitted data signals from the electronic devices used by the particular passenger.

9. The aircraft cabin communications system of claim 8, wherein each data communication device further comprises a connector attached to the housing and electrically coupled to the source of white light for providing power, the connector also electrically coupling the data transmitting device and the data receiving device to the data bus.

10. The aircraft cabin communications system of claim 8, wherein each data communication device further includes a data transmission controller coupled to the data receiving device and the data transmitting device, the data transmission controller configured to determine when data signals transmitted to the electronic devices used by the corresponding passenger are interfered with, and configured to control the data transmitting device to retransmit the data signals if it is determined that the data signals have been interfered with.

11. The aircraft cabin communications system of claim 10, and further comprising data playback buffers coupled to electronic devices used by the corresponding passengers, the data playback buffers receiving data transmitted from corresponding data communication devices and storing the data for time delayed playback to the corresponding passengers.
