Spaced apart sterilization lights in an aircraft cabin

A pathogen sterilization light assembly for a vehicle cabin, comprising:

• a plurality of sterilization lights mounted at spaced apart locations along a cabin of the vehicle and configured to emit ultraviolet light directed toward areas within the cabin to sterilize pathogens, wherein the sterilization lights are divided into groups;
• a power controller and power switches which are connected to alternate between allowing power distribution from a power supply and ceasing power distribution from the power supply to different ones of the groups of the sterilization lights, wherein the power controller is configured to separately control the power switches to select which of the groups of the sterilization lights is powered by the power supply at a time;
• wherein a number of the sterilization lights in the groups which is connected through a same one of the power switches is defined based on at least one of:
• a maximum power distribution of powerlines extending through the cabin to power the sterilization lights in the group and a maximum power supply rating of a power source supplying power to the power switches for distribution;
• and
• the power controller is configured to separately control the power switches to not power-on more than one of the groups of the sterilization lights a time.

• and
• a plurality of powerline communication transceiver circuits connected to powerlines connected to supply power from the power supply to the groups of sterilization lights,
• wherein the plurality of powerline communication transceiver circuits are spaced apart in the cabin and each connected to one of the power switches, and
• wherein the power controller communicates group selection commands through the powerline communication transceiver circuits and the powerlines to control switching of the power switches.

A pathogen sterilization light assembly for a vehicle cabin, comprising:

• a plurality of sterilization lights mounted at spaced apart locations along a cabin of the vehicle and configured to emit ultraviolet light directed toward areas within the cabin to sterilize pathogens;
• and
• a power controller configured to select a group of the sterilization lights to be powered-on during a sterilization procedure based on flight information that includes at least one of:
• a duration of time between passenger deboarding at an end of a flight and passenger boarding for a next flight;
• a seating assignment that indicates which passenger seats or rows of passenger seats were occupied on a previous flight;
• and a seating assignment that indicates which passenger seats or rows of passenger seats are to be occupied on a next flight, and to control initiation and cessation of supply of power to the selected group of the sterilization light.

A pathogen sterilization light assembly for a vehicle cabin, comprising:

• a plurality of sterilization lights mounted at spaced apart locations along a cabin of the vehicle and configured to emit ultraviolet light directed toward areas within the cabin to sterilize pathogens;
• a rotational motor configured to rotate at least one of the sterilization lights relative to at least one passenger seat to scan a focused beam of ultraviolet light along surfaces of the at least one passenger seat;
• and
• a controller connected to control the rotational motor to control angular rotation, range of rotation, and/or rate of angular rotation of the at least one sterilization light based on information indicating at least one of:
• whether the at least one passenger seat has been occupied on a previous flight;
• whether the at least one passenger seat is assigned to be occupied on a next flight;
• how many times the at least one passenger seat has been occupied on previous flights since a last sterilization process has been performed;
• and/or a total time duration the at least one passenger seat has been occupied on one or more previous flights since a last sterilization process has been performed.
