Abstract

Claims (28)

1 . A disinfection system for a vehicle, the disinfection system comprising:

a first light source arranged in an interior of the vehicle and configured to generate radiation in a range of 100-300 nm;

a second light source arranged in the interior of the vehicle and configured to generate radiation in a range of 210-230 nm;

at least one identification unit configured to identify whether there are passengers in the vehicle; and

a controller configured to control the first and second light sources based on whether there are passengers in the vehicle so that when there are no passengers in the vehicle the controller activates the first light source for a first period of time and when there are passengers in the vehicle the controller activates the second light source for a second period of time.

2 . The disinfection system of claim 1 , wherein the first light source is configured to generate radiation in a range of 200-300 nm and the second light source is configured to generate radiation in the range of 222 nm.

3 . The disinfection system of claim 2 , wherein the second light source is configured to generate radiation having a radiation concentration of at least 12 mJ/cm 2 .

4 . The disinfection system of claim 1 , wherein the at least one identification unit is a camera or a radar.

5 . The disinfection system of claim 1 , wherein at least one of the first light source and the second light source is comprised in a single lighting unit or is comprised in separate lighting units.

6 . The disinfection system of claim 1 , wherein the first time period is longer than the second time period.

7 . A vehicle, comprising:

an interior; and

a disinfection system comprising

a first light source configured to generate radiation in a range of 100-300 nm;

a second light source configured to generate radiation in a range of 210-230 nm;

at least one identification unit configured to identify whether there are passengers in the vehicle; and

a controller configured to control the first and second light sources based on whether there are passengers in the vehicle so that when there are no passengers in the vehicle the controller activates the first light source for a first period of time and when there are passengers in the vehicle the controller activates the second light source for a second period of time,

wherein the first and second light sources are fixed on a roof in the interior of the vehicle, on a bearing pillar of the vehicle, or on a console of the vehicle.

8 . The vehicle of claim 7 , wherein the first and second light sources are arranged next to each other such that a radiation propagation of the first light source and a radiation propagation of the second light source are identical within the interior of the vehicle.

9 . The vehicle of claim 7 , wherein the first time period is longer than the second time period.

10 . A method for controlling a disinfection system of a vehicle, the method comprising:

determining, by a controller of the disinfection system, whether there are passengers in the vehicle based on information provided by at least one identification unit; and

switching on one of a first and second light source depending on whether or not there are passengers in the vehicle,

wherein the first and second light sources are arranged in an interior of the vehicle, wherein the first light source is configured to generate radiation in a range of 100-300 nm, and wherein the second light source is configured to generate radiation in a range of 210-230 nm, and

wherein the first light source is switched on for a first period of time when there are no passengers in the vehicle and the second light source is switched on for a second period of time when there are passengers in the vehicle.

11 . The method of claim 10 , wherein the at least one identification unit is a camera or a radar.

12 . The method of claim 10 , wherein the first period of time is at least 6 seconds and the second period of time is at least 2.5 seconds.

13 . The method of claim 10 , wherein the first period of time is longer than the second period of time.
