Abstract

To provide a lighting system which can solve the inconvenience experienced by a pilot entering and leaving a control cabin of a transport such as an aircraft. A lighting system LS of an aircraft 1 includes: lights 21 that illuminate a control cabin 15; a lighting power supply system 22 including a main path 22M which supplies power to the lights 21 and a sub path 22S which supplies power to the lights 21; a first switch SW1 that enables and disables power supply through the main path 22M; and a second switch SW2 that enables and disables power supply through the sub path 22S.

Claims

1. A lighting system of a transport comprising:

a lighting device that illuminates a control cabin of the transport;

a lighting power supply system including a first path which supplies power to the lighting device and a second path which supplies power to the lighting device;

a first switch that enables and disables power supply through the first path; and

a second switch that enables and disables power supply through the second path,

wherein the first switch switches the power supply to the second switch.

2. The lighting system of a transport according to claim 1

wherein the first path and the second path are selectively used.

3. The lighting system of a transport according to claim 1

wherein the second path is enabled only when the first switch is in an OFF state.

4. The lighting system of a transport according to claim 1,

wherein the transport includes an doorway that allows entrance and exit to/from the transport, and an entrance room that faces the doorway,

the control cabin leads to the doorway through the entrance room,

the first switch is located in the control cabin, and

the second switch is located in the entrance room.

5. The lighting system of a transport according claim 4,

wherein the power supply through the second path is enabled by turning ON the second switch when entrance into the control cabin or the entrance room is detected.

6. The lighting system of a transport according claim 1,

wherein the power supply through the second path is enabled by turning ON the second switch when entrance into the control cabin is detected.

7. The lighting system of a transport according claim 1,

wherein the first switch comprises a first contact that is connected to a ground, and a second contact that is connected to the second path.

8. The lighting system of a transport according claim 7,

wherein the first switch is switchable to either the first contact or the second contact.

9. An aircraft comprising

the lighting system of a transport according to claim 1,

wherein the transport is an aircraft.

10. The aircraft according claim 9,

wherein the control cabin is a flight deck of the aircraft.

11. A lighting system of a transport comprising,

a lighting device that illuminates a control cabin of the transport;

a lighting power supply system including a first path which supplies power to the lighting device and a second path which supplies power to the lighting device;

a first switch that enables and disables power supply through the first path; and

a second switch that enables and disables power supply through the second path,

wherein when a power switch for a control system used for controlling the transport is turned ON,

the second switch is turned OFF to disable the power supply through the second path, and

when the power switch is turned OFF,

the first switch is turned OFF to disable the power supply through the first path.

12. The lighting system of a transport according to claim 11,

wherein the transport includes a doorway that allows entrance and exit to/from the transport, and an entrance room that faces the doorway,

the control cabin leads to the doorway through the entrance room,

the first switch is located in the control cabin, and

the second switch is located in the entrance room.

13. The lighting system of a transport according claim 11,

wherein the power supply through the second path is enabled by turning ON the second switch when entrance into the control cabin is detected.

14. An aircraft comprising

the lighting system of a transport according to claim 11,

wherein the transport is an aircraft.

15. The aircraft according claim 14,

wherein the control cabin is a flight deck of the aircraft.

16. A lighting system of a transport comprising,

a lighting device that illuminates a control cabin of the transport;

a lighting power supply system including a first path which supplies power to the lighting device and a second path which supplies power to the lighting device;

a first switch that enables and disables power supply through the first path; and

a second switch that enables and disables power supply through the second path,

wherein the second switch is provided outside of the control cabin.

17. An aircraft comprising

the lighting system of a transport according to claim 16,

wherein the transport is an aircraft.

18. The aircraft according claim 17,

wherein the control cabin is a flight deck of the aircraft.
