Example embodiments described herein involve a system for testing a light-emitting module. The light-emitting module may include a mounting platform configured to hold a light-emitting module for a camera. The mounting platform may also be configured to rotate. The system may further include a housing holding a plurality of photodiodes arranged in an array over at least a 90 degree arc of a hemisphere. The system may also include a controller configured to control the photodiodes and the rotation of the mounting platform.

A vehicle in-cabin lighting system includes: an outward gaze guiding section that is provided inside a vehicle cabin at a vehicle front side and at a vehicle width direction outer side of a vehicle seat, and that becomes brighter than its surroundings on activation of an outer side lighting device; and a control section that is configured to determine whether or not an occupant sifting on the vehicle seat has an interest in interacting with another occupant inside the vehicle cabin based on detection of operation of an operation section by the occupant or based on detection of a state of the occupant, and to activate the outer side lighting device so as to make the outward gaze guiding section brighter in a case in which determination is made that there is no interest in interacting.

A lighting device for a grab handle in a vehicle includes the grab handle disposed in a passenger compartment, a lamp embedded in the grab handle, a key sensor capable of detecting an approach of a user having a key into a given range around the vehicle, and a lighting controller configured to control lighting mode of the lamp. The lighting controller controls the lamp [1] to light the lamp in a first lighting mode when user's approach information is input to the lighting controller, [2] to light the lamp in a second lighting mode when lock/unlock information of a door is input to the lighting controller, or [3] to light the lamp in a third lighting mode when open/close information of the door is input to the lighting controller.

The invention relates to a lighting device having dynamic lighting effects for the passenger compartment of a motor vehicle. The lighting device includes a lighting system configured to emit at least one light signal producing a dynamic effect of scrolling inside the passenger compartment in order to simulate the scrolling of the road inside the passenger compartment of the vehicle.

A vehicle system includes a warning device and at least one electronic control unit. The at least one electronic control unit is configured to present a light stimulus to a driver, and determine whether the driver is facing forward, determine whether the driver holds a steering wheel, and cause the warning device to perform a first warning when it is determined that the driver is not facing forward while the light stimulus is being presented. The first warning is either the vibration or the sound. The at least one electronic control unit is configured to perform a second warning when it is determined that the driver does not hold the steering wheel before a predetermined time elapses after the first warning is started. The second warning includes the vibration and the sound.

An indoor lighting device of a vehicle includes: a substrate, a plurality of light sources assembled with the substrate to be arranged in a row, and a light guide panel including: a plurality of incidence parts such that light emitted by the light sources is incident thereupon, a diffusion area part provided behind the incidence parts to diffuse and reflect the light incident upon the incidence parts, a visual field area part provided behind the diffusion area part to emit the light diffused and reflected by the diffusion area part outside, and light diffusion holes provided behind the respective incidence parts. In particular, each of the light diffusion holes is surrounded by a transmission plane, a pair of reflection planes and a diffusion plane.

Provided are an apparatus and a method for analyzing a state of a vehicle occupant and performing illumination and image output control by a projector in units of a screen sectioned area of a vehicle ceiling, in accordance with an analysis result. There is provided a data processing unit configured to execute state analysis of an occupant of a vehicle and execute output control of a projector in accordance with an occupant analysis result. The data processing unit performs projector control of outputting illumination light having luminance determined in accordance with the occupant analysis result, in units of a sectioned area of a screen of a vehicle ceiling on which projector output light is outputted. The data processing unit analyzes a state of an occupant on the basis of a camera-captured image, and outputs illumination light having luminance determined in accordance with an occupant state, in units of a screen sectioned area above each occupant.
