A system for controlling interior lighting of a mobility device may change a lighting environment inside a mobility device based on outside environmental factors and the state of an occupant, thereby improving an interior aesthetic property, ensuring the occupant's convenience, and enabling safe traveling.

The invention relates to an illuminant device for emitting light of a continuously adjustable colour, more particularly for individualizing and/or illuminating an interior, comprising the following: at least one illuminant unit comprising a plurality of illuminant elements; at least one driver unit which is configured to output driver current signals to the illuminant elements of the illuminant unit in such a way that a target colour of the illuminant unit can be set in accordance with the driver current signals; at least one computing unit, which is configured to calculate the driver current signals necessary for setting the target colour and to control the driver unit accordingly so that the driver unit outputs the driver current signals.

When light is off, a transparent appearance is obtained, while when the light is on, light is seen through a transparent spot. The present invention includes a light source portion and a reflective portion. The light source portion emits light. The light source portion is disposed at a position shifted with respect to an emitting direction of emitted light from the reflective portion. The reflective portion reflects the light from the light source portion and emits it in a predetermined direction. The reflective portion is constituted by a transparent member with a refractive index at least in a visible light area larger than 1. As a result, in the present invention, the transparent appearance is obtained when the light is off, while the light is seen through the transparent spot when the light is on.

A vehicle lighting device includes: a first optical system including a light source and a first lens; a second optical system including a light source and a second lens; and a housing configured to house the first optical system and the second optical system. The first optical system is configured to illuminate an interior of a vehicle. The second optical system is configured to display predetermined information to the outside of the vehicle.

A motor vehicle cabin sensing system is disclosed. The system comprises an image sensor, an illumination source and an illumination lens array. The image sensor is operable to capture one or more images, the image sensor having a field of view of a motor vehicle cabin. Preferably, the image sensor is operable to capture images in a near infrared wavelength. The illumination source is operable to transmit light rays towards the motor vehicle cabin. The illumination lens array is operable to diffuse the light rays emitting from the illumination source to one or more photoreceptor cells of a retina such that a radiant intensity of a red glow effect detected by the retina is a reduction of 10 to 100 times or 0% to 50% of a radiant intensity of the illumination source. A method is also disclosed.
