This illumination device includes an organic EL illumination panel installed in a baggage rack or the like in a fuselage of an aircraft, and a panel driving circuit that drives the organic EL illumination panel and is installed in a different place apart from the organic EL illumination panel in the fuselage to drive the organic EL illumination panel. The organic EL illumination panel includes a plurality of light emitting units including at least a light emitting layer, and a charge generation layer arranged between the plurality of light emitting units to thereby form a multi-photoemission structure, and has a thickness of 5 mm or less in a stacking direction.

The lighting management device comprises a variable lighting system which includes: at least one exterior light sensor, that is capable of measuring the characteristics of the exterior light outside the vehicle, and at least one interior image capture device, that is capable of capturing images within the interior of the compartment; and a control unit for controlling the lighting system, configured so as to adjust the lighting in the compartment based on the brightness of the exterior light measured outside the vehicle and the images captured within the interior of the compartment.

The control device individually controls operations of the two or more lighting devices. Each lighting device includes a light source, a sensor for measuring light intensity of the light source, and a controller circuit for controlling the light source. The control device includes a replacement detector circuit, and the replacement detector circuit determines whether any of the lighting devices has been replaced, and obtains a determination result distinguishing a replacement lighting device from remaining lighting device(s). When the replacement detector circuit has obtained the determination result, the control device controls at least one of the lighting devices based on the measurement value outputted from the sensor of the replacement lighting device and the measurement value(s) outputted from the sensor(s) of the remaining lighting device(s), so that a difference between light intensity of the replacement lighting device and light intensity derived from the remaining lighting device(s) falls within a predetermined range.

A pathogen sterilization light assembly for a vehicle cabin is provided herein and may include a plurality of sterilization lights mounted spaced apart along a cabin of the vehicle and configured to emit ultraviolet (UV) light directed toward areas within the cabin to sterilize pathogens.
