A vehicle headlight device comprising: a low-beam lamp and a high-beam lamp that illuminates a first light distribution region that is in front of the vehicle with light; and a patterned-light emitter that illuminates a second light distribution region with light in an illumination pattern in which bright regions and dark regions alternately repeat, the second light distribution region being further toward an outer side than the first light distribution region in the vehicle width direction, wherein the patterned-light emitter emits light such that intervals between the bright regions that are adjacent are wider at a position further ahead of the vehicle than at a position closer to the vehicle in a traveling direction of the vehicle.

A lighting device to be mounted on a vehicle has a light source, a projection lens having an optical axis, and disposed so as to allow at least some of light emitted from the light source to pass therethrough, a holder that holds the projection lens, a pivot shaft provided at one of the projection lens and the holder and extending in a direction intersecting with the optical axis of the projection lens, a bearing provided at the other of the projection lens and the holder and that holds the pivot shaft, and an aiming mechanism configured to pivot the projection lens relative to the holder about the pivot shaft.

A light bar is described that is of a modular construction based on one or more large circuit boards that are populated with light beam assemblies and then fastened to an interior space of the light bar housing. Keys that automatically align the light beam assemblies on each of the boards precisely control placement of the assemblies on the board. In turn, each of the boards is keyed to the interior of the light bar housing so that when the board is fastened to the housing the light beam assemblies are automatically registered into alignment with the lenses in the housing so that the beams from the assemblies are properly oriented. The light bar is inexpensive to fabricate and can be assembled quickly and reliably, yet it provides for a high degree of customization, which is a requirement in the emergency vehicle lighting industry.

An automotive lightguide includes a main guide portion with a light entrance surface and a reflective rear edge surface; and an exit lens joined to the main guide portion, the exit lens having an exit surface with an arcuate exit profile. In use, light rays from a light source enter the main guide portion through an entrance surface, travel through the main guide portion and reflect off the rear edge surface to the exit lens which images the reflected light rays as a light beam pattern having a predetermined sharp horizontal cutoff and a predetermined horizontal spread, the arcuate profile of the rear edge surface determining the horizontal cutoff and vertical spread of the light beam pattern with respect to the horizontal optical axis H-H, and the exit profile of the exit lens determining the horizontal spread of the light beam pattern.

An optical module for a lighting and/or signaling device of a vehicle, comprising at least one light source capable of generating a light beam, a cooling device capable of dissipating heat and a device for focusing the light beam, characterized in that the focusing device is borne directly by the cooling device.

A lighting arrangement includes a lighting chamber having a light-permeable section and a ventilation opening with a filtering membrane. A light source for supplying light is arranged in the lighting chamber. A ventilation arrangement is assigned to the ventilation opening so as to supply ambient air through the ventilation opening to the lighting chamber. The ventilation arrangement includes an air outlet opening assigned to the ventilation opening of the lighting chamber so as to supply the ambient air to the ventilation opening. A distance between the air outlet opening and the filtering membrane is configured so as to be adjustable.

A vehicle headlight device including a low-beam lamp and a high-beam lamp that emit light into a first light distribution region that is in front of a vehicle, and a patterned-light emitter that emits light into a second light distribution region in an illumination pattern in which bright regions and dark regions alternately repeat, the second light distribution region being further toward an outer side than the first light distribution region in a width direction of the vehicle. The patterned-light emitter emits light such that at least part of a region of the illumination pattern has a movement that is different from other regions of the illumination pattern.
