A lighting device for a vehicle, in particular a headlight, including a light source, from which light emerges in operation of the lighting device, a collimation optical system having an incident face and an emergent face, which the light emerging from the light source passes through, a projection optical system having a first array of lenses and a second array of lenses, wherein the light emerging from the collimation optical system first passes through the first array of lenses and after that through the second array of lenses, as well as a diaphragm, which the light passes through, wherein the diaphragm is arranged in front of the first array of lenses, so that in operation of the lighting device the light does not strike the first array of lenses until after passing through the diaphragm.

A primary optic for a headlamp of a motor vehicle is provided. The primary optic is a multi-component injection molding comprising at least two injection molded photometrical components coupled to each other, whereby the at least two photometrical components are arranged to consecutively receive light emitted by a light source.

A light-emitting device includes: a mounting board; a light-emitting element disposed on or above the mounting board; a plate-shaped light-transmissive member having: a first surface; and a second surface facing a light-emitting surface of the light-emitting element; a light-reflective member covering a lateral surface of the light-transmissive member; and a light-shielding frame on an upper surface of the light-reflective member around the light-transmissive member. The light-shielding frame has an opening. An inner perimeter of the opening is located apart from outer perimeters of the first surface and the second surface of the light-transmissive member in a top plan view. The light-reflective member is disposed between the inner perimeter of the opening and the outer perimeters of the light-transmissive member.

A turn light, a position light and a driving light are provided inside a same headlight unit, a first lens for which a first light source for the turn light and a second light source for the position light and the driving light are alternately arranged and a second lens which is arranged below the first lens and on which light from the first light source and the second light source is made incident are provided, a first diffusion part is provided on a light exit surface of the light of the first lens, and a second diffusion part is provided on a light exit surface of the light of the second lens.

Disclosed herein is a vehicle headlight for improving visibility during operation. In the vehicle headlight, a filtering film capable of preventing glare and reducing a discomfort glare phenomenon by controlling scotopic vision (S)/photopic vision (P) ratio in such a manner as to selectively absorb/block blue light in light emitted from an LED module is adhered, thereby improving visibility during operation.

A lighting and/or signaling device comprising a container body which delimits a containment seat that houses a first luminous source adapted to emit a first luminous beam, and a second luminous source adapted to emit a second luminous beam. The containment seat adapted to be at least partially crossed by the luminous beams produced by said luminous sources, so as to transmit the luminous beams outside the containment seat. The containment seat is divided into a first compartment which houses the first luminous source and into a second compartment which houses the second luminous source. The lenticular body comprises a first transmission portion, facing the first compartment that transmits, at least partially, towards the outside the first luminous beam, a second transmission portion facing the second compartment that transmits, at least partially, towards the outside the second luminous beam. An opaque portion, is interposed between the first and second transmission portions so as to conceal the view of the first and second luminous sources.

An optical member includes: a body portion having a first upper surface, and a second upper surface that is located above the first upper surface and surrounds the first upper surface in a plan view; a phosphor member disposed on the first upper surface; and a hold-down portion configured to secure the phosphor member such that the phosphor member is interposed between the hold-down portion and the body portion.

An optical element, comprising a light guide body. The light guide body comprises a plurality of light-incident parts arranged along a length extension direction of the light guide body, a light guide part and a light-emitting part; each light-incident part is provided with at least one light-incident unit; the light guide part is configured to guide light received by each light-incident unit to be emitted toward the light-emitting part; the shape of a forward projection plane of the light-emitting part is of a strip shape. The optical element can reduce the occupied space and improve the space utilization rate, facilitates reducing positioning mounting errors, has an appearance with a narrow and elongated shape, and can be applied in vehicle lamp modules, vehicle lamps and vehicles.

The invention relates to a lighting device, for a motor vehicle, including a plurality of light sources, which have a plurality of primary lenses dedicated to each of the respective light sources for focusing the light emitted by the respective light sources. The lighting device also has a secondary optics element which has a plurality of light entry surfaces dedicated to each respective light source and one light exit surface. A grid is located downstream of the light exit surface on the secondary optics element in the exit direction of the light, for segmenting the light exiting the light exit surface.

A vehicular lamp includes: a main light source that emits light for forming a predetermined irradiation pattern; an optical member that allows the light emitted from the main light source to travel toward a front side in an irradiation direction to form the irradiation pattern; a heat dissipation member that releases heat from the main light source to outside; and a light guide member that guides light from an auxiliary light source provided as a separate body from the main light source. In the heat dissipation member, the heat dissipation member is provided with an opening part that opens a mounting surface provided with the main light source, and the light guide member guides light from the auxiliary light source toward the mounting surface through the opening part.
