An aircraft light is provided which can illuminate an illuminated area with appropriate levels of illuminance. An aircraft light is configured, including: at least one or more light-emitting elements as light sources; and an inner lens configured to project light emitted from the light-emitting elements onto a desired area, in which the inner lens has a lens that splits light of a single light-emitting element in different directions. According to this aspect, both a far illumination area and a near illumination area can be illuminated, and the luminous intensity can also be adjusted by adjusting the amount of a beam to be split; therefore, an illuminated area can be illuminated with appropriate levels of illuminance.

A lamp unit includes: a first unit including a light emitting unit; a second unit including a light source and a lens unit having a shape different from that of the light emitting unit; and a shielding portion having an opening portion and shielding a member provided on a back side of the shielding portion from the outside. The first unit is disposed at a position where the light emitting unit is capable of being visually recognized from the outside in a front view. The lens unit is disposed on the back side of the shielding portion or in the opening portion. At least a part of the lens unit is provided at a position where at least the part is invisible in a front view, and light emitted from the light source is projected forward via the opening portion provided in the shielding portion.

A display device includes a projection device RP that projects a notification pattern on a region in the vicinity of a vehicle CAR, an imaging device RC that images the region in the vicinity of the vehicle, and an object detection device OS capable of detecting an object (third party) present in a region which cannot be imaged by the imaging device RC. When the object detection device OS detects the object, the projection device RP projects the notification pattern in a form different from the notification in a normal state, so that the third party can visually recognize the notification pattern. The imaging device RC images a region including a region on which the notification pattern is projected, and displays, on a monitor MO visually checkable by the occupant, a captured image of the notification pattern projected in the form different from the notification pattern in the normal state.

A light-emitting module and a vehicle, the light-emitting module having a main light exit direction. The light-emitting module includes a first light source, used for a first light function, a first reflector for receiving and reflecting light emitted from the first light source. A second light source is used for a second light function, and a second reflector is for receiving and reflecting light emitted from the second light source. A carrier, has the light sources and the reflectors arranged thereon, and a lens, for projecting light emitted from the light sources and reflected by the corresponding reflectors. The lens is configured to correspondingly form light distributions associated with the reflecting surfaces of the first reflector and the second reflector, and the first light source, the first reflector, the second light source and the second reflector are arranged on the same mounting surface of the carrier.

A lighting device for a motor vehicle includes numerous light sources and a collimator with numerous collimator lenses. Each collimator lens has an entry surface and an exit surface through which light from the light sources passes successively. Projection optics include a first and second transparent substrates, each with an entry surface and an exit surface. At least one array of cylindrical lenses are on the entry and/or exit surface of the first and second substrates. Light exiting the collimator first passes through the at least one array of cylindrical lenses on the first substrate and then through the at least one array of cylindrical lenses on the second substrate. The projection optics include a first array of cylindrical lenses on the first substrate, the cylinder axes of which extend in a first direction, which is horizontal when the lighting device is installed in a vehicle.

A dia for an automotive dia projection system has a transparent substrate with an opaque coating in portions thereof, thereby forming a binary pattern for projection. The pattern features a dither noise microstructure, such that an associated image is projectable giving the perception of a greyscale image to the human viewer.

Disclosed is a vehicle projection lamp that improves the definition of an image. An aspect of the present embodiment provides a vehicle projection lamp that reduces a distortion occurring in an image and improves the definition of the image when outputting the image to the ground. The projection lamp includes a light source; a substrate; a collimator located in front of the light source; a lens array unit; a fixing unit; an upper housing; and a lower housing.

Provided are a lamp unit that can form an irradiation pattern on a road surface almost without tilting an inclination of a lamp unit axis with respect to the road surface, and a vehicle lighting tool using the lamp unit. A lamp unit includes: a light source; a condenser lens that condenses light from the light source; a light-shielding member (shade) provided with an irradiation slit through which the light condensed by the condensing lens partially passes; and a projection lens that projects the light that passes through the light-shielding member (shade) to form an irradiation pattern, which are arranged along a lamp unit axis. The projection lens has a reference focus set on the lamp unit axis, and is disposed at such a position rotated downward about the reference focus, and a projection lens axis is directed further downward than the lamp unit axis.

The invention relates to an optical device for projecting light beams, capable of cooperating with a pixelated light source, including a plurality of selectively activatable emissive elements, which consists of the following components, arranged in succession along the path of the light rays from the source: a convergent first lens, a divergent or neutral second lens, a pupil and a convergent third lens.

The optical device is intended to be placed in a housing to form a light signal lamp for a vehicle. The optical device includes, along the longitudinal direction: an input portion receiving rays emitted by a light source; a middle portion having two lateral faces spaced from each other along a transverse direction; an output portion including an output face through which the rays which have propagated in the optical device are emitted. The output portion comprises at least one module having lateral faces which, when viewed in the elevation direction, have an ogive shape and which define a front ridge extending substantially in a plane parallel to a plane.
