A lamp for a vehicle includes a light source unit that generates light and an optical unit for guiding the light. The light source unit includes a plurality of light sources arranged in a matrix shape, and the optical unit includes a plurality of optical members disposed in a traveling direction of the light. The light generated from the plurality of light sources passes through the optical unit to form a beam pattern.

A hidden light device for a vehicle is configured to emit light from a grill of the vehicle, and when the light is not emitted, aesthetics of the grill may be maintained. The hidden light device includes: the grill having an outer surface forming a pattern composed of a plurality of grids; grid panels provided to some or all of the plurality of grids, respectively; and an optical module provided inside each of the grid panels to allow the grid panels to form the pattern of the grill when turned off, and to emit light through the grid panel when turned on so as to make the grid panel serve as lighting of the vehicle.

Light-based devices may be provided that emit light. The light-based devices may be incorporated into systems such as vehicles. The light-based devices may include light sources such as light-emitting diodes and lasers. Mirrors may be used to collimate light from the light sources. Light modulators may be used to pattern light from the light sources. The light sources may include light sources of different colors. Arrays of pixels may be used to provide dynamically varying patterns of emitted light. A light source may produce light that is diffracted by an array of diffractive elements on a window. Mechanical and electrical shutters may obscure light sources, mirrors, and light-emitting components mounted on windows.

A vehicle lamp structure 1 comprises an inner lens 3 scattering light from a light source, and a reflector 4 that is disposed inward of the inner lens 3 in a vehicle inside-outside direction and reflects the light from the inner lens 3, the reflector 3 including a first face 4a that is disposed so as to intersect with the vehicle inside-outside direction and a second face 4b that is disposed so as to intersect with an up-down direction and connected with the first face 4a at a predetermined angle θx to the first face 4a.

An improved light assembly includes aligned directional light sources mounted one behind another. A distal one of the light sources occludes light emitted from a proximal one of the light sources. A reflector is interposed between the light sources, with a convex surface facing the proximal one of the light sources. Thus, the light assembly projects a light field extending at least through an 180° hemisphere, and up to about 270° backwards from the forward orientation of the light field, well-illuminating lateral approaches to the assembly.

A light guide has an elongated body that includes an entrance face at which light is admitted into the light guide and an exit face at which the light emanates from the light guide. The light guide has an inboard side wall and an outboard side wall extending between the entrance face and the exit face. The entrance face, the exit face, the inboard side wall and the outboard side wall enclose a medium containing a colorant by which the medium meets a color criterion while minimizing light absorption at a wavelength of the light.

A lighting system of a vehicle may include light units and controllers for operating the light units. Each light unit is multifunctional in that the light unit may operate in various modes, which may be invoked at different times under varying circumstances. A light unit on the first end of a vehicle may operate as a headlight if the first end is the front end of the vehicle. On the other hand, the light unit may operate as a tail light if the first end is the rear end of the vehicle. Furthermore, the light unit may operate as a turn signal in either direction or brake light while the first end is the rear end of the vehicle. The light unit includes a lens array positioned to receive light from various light sources. The lighting system may operate in a fashion that allows for lighting redundancy on each end of the vehicle in the event of a lighting controller failure.

A vehicle lamp includes a light source unit including a first light source and a second light source, a reflector which includes a plurality of first reflecting surfaces sharing a first focal point at a position corresponding to the first light source and a plurality of second reflecting surfaces sharing a second focal point at a position corresponding to the second light source, and which has a shape by which the first reflecting surfaces and the second reflecting surfaces diffuse a white light from the first light source and an orange light from the second light source in the right-left direction in an in-vehicle state, and an inner lens that emits the white light and the orange light reflected by the plurality of first reflecting surfaces and the plurality of second reflecting surfaces from a common emission surface to the front of a vehicle.
