20210070219 · 2021-03-11 · ·

The present invention proposes a lighting device for a motor vehicle comprising a first module that projects a first pixelated high beam, a second module that projects a second pixelated writing beam onto the road, and a third module that projects a third low beam cut-off. The first, second and third modules are arranged such that the first and second beams overlap at least partially vertically; and the second and third beams overlap at least partially vertically.

A system and method involve driver-side high beams to be selectively deactivated for oncoming traffic. It is intended to allow passenger-side high beams to continue operation to preserve the driver's peripheral vision. The driver's side high beam is manually controlled by a separate switch. During use, when an oncoming vehicle approaches, the activation of the switch allows the driver to deactivate only the driver side high beam while the passenger side high beam remains activated. This produces a situation in which the oncoming driver is no longer blinded, but the vehicle driver still maintains the extended vision of the high beam on the left-hand side of the vehicle.

Headlight, in particular headlight of a motor vehicle

A headlight, in particular a headlight of a motor vehicle, having at least one first light source for a high beam, which emits light during operation of the headlight, and a first light guide having at least one light entry surface for the light emerging from the at least one first light source and at least one light exit surface, and at least one second light source for a low beam, which emits light during operation of the headlight, and a second light guide, which has at least one light entry surface for the light, emerging from the at least one second light source, and at least one light exit surface.

Adaptive beam scanning headlamp

An adaptive beam scanning headlamp for a vehicle includes a plurality of light sources arranged linearly, with each of the plurality of light sources having a linear array of LEDs. A plurality of primary projection lenses shape light from the plurality of light sources. An oscillating mirror obliquely angled between the plurality of primary projection lenses and a secondary projection lens receives light from the plurality of primary projection lenses and redirects the light to the secondary projection lens. The secondary projection lens is adapted to further shape the light for projecting a beam pattern from the vehicle. A controller is adapted for controlling each of the plurality of light sources and the oscillating mirror to actively dim or turn off portions of the beam pattern for reducing glare perceived outside the vehicle.

Adaptive headlamp for optically and electronically shaping light

An adaptive driving beam headlamp includes a plurality of light-emitting diodes (LEDs) aligned in a first direction. One or more projection lenses having a toric-shape are adapted for shaping light emitted from the plurality of LEDs along the first direction. A beam shaping optic is adapted to shape light emitted from the one or more projection lenses along a second direction, different from the first direction, such that a desired beam shaping pattern is produced by the beam shaping optic in combination with the one or more projection lenses. A controller is adapted for independently controlling each of the plurality of LEDs for adaptively dimming portions of a vehicle headlamp beam of light.
