A lighting device comprising at least two LED light sources, powered and activated separately, each facing a respective light input wall of a corresponding light guide, the light guides transmit and emit the light of the LED light sources through at least two distinct lighting faces at a front wall of the lighting device. The light guides are provided with diffuser extractor elements arranged on a rear wall of the light guide, opposite the front wall, and shaped so as to extract the light outside the lighting device. The light guides are juxtaposed and adjacent to each other at at least one respective inner wall. The light guides are mechanically and optically separated by barrier elements which prevent the passage of light between the light guides at one inner wall. The barrier elements are separator septa opaque to the light extending from the rear wall to the front wall, crossing it completely.

The light guiding unit is disposed in front of the supporting unit and the lens is disposed in front of the light guiding unit. Therefore, the light utilization efficiency of the light projecting device can be increased while satisfying requirements for miniaturization.

A bank angle of a vehicle can be accurately calculated using yaw axis data and roll axis data, and based on the calculated bank angle, vehicle illumination optics can be controlled to maintain a pattern of distributed light from the illumination optics to be generally horizontal. The calculated bank angle may be zeroed when the yaw axis data equals zero. The improved pattern of distributed light from the illumination optics illuminates a more natural field of view for the vehicle driver during a bank.

The purpose of the present invention is to provide a vehicular lamp which creates light directed upward using a reflector that allows the light incident below the lower end of the lens to exit upward through a lens and which minimizes the uneven light distribution of the created light distribution pattern. The vehicular lamp according to the present invention includes: a semiconductor light source unit (20) including a light-emitting chip (21); a horizontally long lens (30) disposed in front of the light source unit (20); and a reflector (40) positioned between the lens (30) and light source unit (40) and disposed below the light-emitting chip (21) along a vertical direction. The reflector (40) includes a reflection surface (41) for creating a plurality of virtual focal points intersecting a vertical axis passing through the light emitting center O of the light-emitting chip (21). The distribution of light from the reflection surface (41) is controlled so that light is emitted from a light emitting surface (32) vertically below the optical axis Z of the lens (30). The lens (30) is formed such that, when a point light source is assumed on the optical axis Z, first direct light LM on the optical axis Z emitted from the point light source is distributed upward from the light emitting surface (32).

An optical module for a motor vehicle including a first optical element including light guides and a projection optic arranged at a distance from the first optical element and having a longitudinal optical axis. The light guides are aligned in a series, perpendicular to the longitudinal optical axis and in a transverse direction, and they include first light guides and second light guides. The first light guides are arranged successively with respect to each other by being interposed between the second light guides, the first light guides each having a transverse dimension less than the equivalent transverse dimension of each of the second light guides. The first light guides are predominantly offset transversely with respect to the longitudinal optical axis.
