A vehicle lamp is configured in such a manner as to project light from light-emitting elements (22 and 42) of a first and a second lamp unit (20 and 40) forward through lenses (30 and 50) in the lamp and accordingly form a low-beam light distribution pattern having a Z-shaped cut-off line. In addition, a part of a plurality of lens elements formed on a front surface (30a, 50a) of each of the lenses (30 and 50) is formed as a specific lens element (30aA3, 50sB3) having a freeform surface shape. It is configured in such a manner as to form an inclined portion of the Z-shaped cut-off line with light emitted from the specific lens elements (30sA3 and 50sB3). Consequently, the degree of flexibility in forming the Z-shaped cut-off line is increased.

A high-definition lamp unit contains a plurality of individually controllable pixels, and emits lamp beam having light distribution corresponding to states of the pixels. A first sensor is provided to enable detection of a dynamic component of a pitch angle of a traveling vehicle body. A controller shifts the level of a cut-off line CL of the light distribution up and down, corresponding to the dynamic component of the pitch angle of the vehicle body, with reference to a predetermined level defined as a base.

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. In some embodiments, the vehicle illumination optics can include a primary illumination group and a plurality of side illumination groups.

Light guiding elements having a light guiding section extending between a light entrance surface for coupling in light and a light exit surface for coupling out light from the light guiding element through the light exit surface. The light exit surface extends along an exit surface longitudinal direction. The light guiding section has at least a first and a second lateral surface extending from the light entrance surface to the light exit surface such that light can be guided by total internal reflection from the light entrance surface to the light exit surface. The form of the light entrance surface differs from that of the light exit surface. The light guiding section has a roof section extending toward the light exit surface in which the first and the second lateral surfaces taper toward each other with respect to the exit surface longitudinal direction.

A device for adjusting high and low beam shape of automotive headlamp comprising a fixed bracket, an adjusted assembly and an up/down and left/right adjusting mechanism. The low beam unit is disposed on the fixed bracket and the high beam unit is disposed on the adjusted assembly. The cylindrical inner hole disposed on the fixed bracket is fitted with the fixed ball head disposed on the adjusted assembly, whereas the elastic waist hole slot disposed on the fixed bracket is fitted with the adjusting bar disposed on the adjusted assembly.

A lighting module for a motor vehicle, including a first lighting submodule with a light source that is able to form a first light beam, a second lighting submodule that is able to form a second light beam, a second projecting lens for projecting the second light beam, adjoining the first projecting lens, and an optical device configured to return, towards the second projecting lens, light rays coming directly from the light source of the first lighting submodule and passing in front of the reflective surface of the first lighting module so as to give the second projecting lens an illuminated appearance while the second lighting submodule is off.

A lens of a vehicular headlight is mounted on a vehicle and includes an incident surface through which light from a light source enters and an emission surface from which light entered from the incident surface is emitted. At an upper edge area including an upper end in an on-board state, the emission surface has a shape allowing a portion of light entered through the incident surface and reached the upper edge area to be internally reflected rearward in the on-board state after being internally reflected toward the incident surface side from the emission surface and internally reflected toward the emission surface side from the incident surface.

A lighting device for a motor vehicle, including a first lighting module with a first lighting engine able to produce a first light beam with cutoff and a first optical device able to project the first light beam, a second lighting module with a second lighting engine able to produce a second light beam, and a second optical device able to project the second light beam, a plate having an inclination with respect to a horizontal plane, about an axis of inclination. The first and second lighting engines being arranged on the plate, with an offset, and the first and second optical devices exhibiting an offset in a vertical direction.

An airbox for an air intake system of an engine includes an air inlet for receiving air into the airbox, an air outlet for discharging air from the airbox, and an airbox body defining first and second expansion chambers fluidly connected to one another. The airbox body has a dividing wall separating the first expansion chamber from the second expansion chamber, the dividing wall defining a wall opening fluidly connecting the first and second expansion chambers. An interchangeable flute is removably connected to the airbox body. The interchangeable flute is at least partly disposed in the second expansion chamber and positioned to guide air flowing into the air inlet into the second expansion chamber. The interchangeable flute is removable such that a replacement flute can be installed in its place to selectively modify a noise output of the airbox. Other aspects are also contemplated.

A headlight for a motor vehicle having at least one light source which emits light during operation of the headlight. A primary optical system has at least one light entry surface for the light emitted by the at least one light source and at least one light exit surface. A secondary optical system, which, during operation of the headlight, projects the light emitted from the at least one light exit surface of the primary optical system into the space outside the motor vehicle where it produces a light distribution which has a horizontal cut-off line and light portions located above the cut-off line in order to implement an OS function (overhead sign function). The headlight being designed such that a portion of the light emitted by the primary optical system is reflected back to the primary optical system by the secondary optical system.
