Vehicle light management device, associated vehicle and method

A light management device for a vehicle, the vehicle comprising at least one car extending mainly in a longitudinal direction, the device comprising:

• a plurality of sensors for measuring a density of passengers on board the vehicle suitable for calculating the density of passengers per zone in the vehicle,
• a plurality of light sources grouped into at least two groups of light sources, each group being associated with a respective zone of the vehicle and each light source of a same group of light sources emitting light radiation with the same optical characteristic,
• a controller connected to each of the sensors for measuring the density of passengers, and to the light sources, the controller being configured to control the optical characteristic of the light radiation of the light sources of the same group of light sources based on the passenger density calculated for the corresponding zone,
• wherein the device comprises at least a second sensor selected from a sensor of the position of the vehicle, and/or a clock, the controller being configured to monitor a first characteristic of the light radiation as a function of a measurement of the sensor for measuring the density of passengers on board the vehicle, and a second characteristic of the light radiation as a function of a measurement of the second sensor.
