A front-lighting system for a vehicle has: a first light source, a second light source, a first primary optics, a second primary optics, a transparent shutter, and a secondary optics. The first primary optics receives light from the first light source and projects it onto the transparent shutter and the secondary optics. The second primary optics receives light from the second light source and projects it onto the transparent shutter. The transparent shutter receives light from the first primary optics and prevents a lower part of it from entering the secondary optics, receives light from the second primary optics and projects it onto the secondary optics, and has a light out-coupling surface and micro-optical structures on a bordering surface. The secondary optics receives light from the first primary optics and the transparent shutter, and projects it onto a road in front of the vehicle.

Lighting module having light-emitting elements with gradual cutoff

A light-emitting module of a lighting/signalling device, in particular for a motor vehicle, including at least one light source including a set of submillimetre-sized light-emitting elements; the light-emitting elements being distributed in a first zone and in a second zone such that the first zone emits a first luminous intensity and that the second zone provides a transition between the first luminous intensity in proximity to the first zone and a second luminous intensity that is lower than the first luminous intensity.

VEHICLE LAMP

A vehicle lamp includes a first lamp unit that includes a light source, a driving unit, and a reflective body that is driven by the driving unit to repeat a periodic motion and thus scans an exit beam from the light source; and a controlling unit that controls the first lamp unit. The controlling unit instructs that the driving unit be driven until a first duration T.sub.1 has passed even in a case where the controlling unit has received an illumination instruction instructing the first lamp unit to emit a beam and then received a stop instruction instructing the first lamp unit to stop emitting a beam.

Vehicular lamp fitting

A vehicular lamp fitting, comprising a projection lens, a separator that is disposed behind the projection lens, a low beam light source and an ADB light source that are disposed behind the separator, wherein the separator includes an upper separator main body, and a lower separator main body, and a first region (a lower portion of an upper entry surface of the projection lens and an upper portion of a lower entry surface of the projection lens) matches the focal plane of the projection lens, a second region (a portion above the lower portion of the upper entry surface of the projection lens) is disposed ahead of or behind the focal plane of the projection lens, and a third region (a portion below the upper portion of the lower entry surface of the projection lens) is disposed ahead of or behind the focal plane of the projection lens.

A lighting device for a vehicle headlight, the lighting device having a first light module (105), a second light module (106) and a third light module (107), wherein, when the modules are installed in a vehicle, the first light module generates a first overall light distribution (A), the second light module generates a first partial light distribution (F), and the third light module generates a second partial light distribution (Z), these distributions being in a region in front of the vehicle. When the first and second light modules are illuminated at the same time, the first overall light distribution at least partially overlaps the first partial light distribution, forming a second overall light distribution (AF). The second partial light distribution lies underneath the hh line and at least partially overlaps the second overall light distribution (AF). When all three light modules are activated simultaneously, a third overall light distribution (AF) is formed.

A vehicle lamp includes: a light source unit including one or more light sources and configured to generate light; a reflector configured to reflect at least part of the light generated by the light source unit; and a lens configured to transmit therethrough a first portion of the light that is generated by the light source unit and that is reflected by the reflector to the lens. The reflector includes: a reflective part configured to reflect, to the lens, the first portion of the light generated by the light source unit; and a non-reflective part configured not to reflect, to the lens, the light generated by the light source unit. The reflective part and the non-reflective part of the reflector are configured to selectively reflect the light generated by the light source unit towards the lens to output a light distribution pattern from the vehicle lamp.

Optical unit

The control part controls a timing of changing the light emission intensity of the first light source and a timing of changing the light emission intensity of the second light source such that a first light-shielding portion is formed in a part of the first irradiation pattern, a second light-shielding portion is formed in a part of the second irradiation pattern so as to overlap with the first light-shielding portion, and a range of the first light-shielding portion and a range of the second light-shielding portion are deviated from each other.
