A vehicle lamp includes a light source and a light guide body configured to guide light from the light source therein and emit the light toward a front side of the lamp. The light guide body includes a first rod-shaped light guide portion configured to guide light incident from an incident end surface, a second rod-shaped light guide portion configured to guide the incident light, and a plate-shaped light guide portion formed in an area between the first rod-shaped light guide portion and the second rod-shaped light guide portion. The plate-shaped light guide portion has an end side surface configured to totally reflect at least a portion of light, which travels in the plate-shaped light guide portion, toward the first rod-shaped light guide portion and/or the second rod-shaped light guide portion.

The invention relates to a lighting device for a motor vehicle, comprising a light guide for the totally reflecting guidance of light from two light sources along a light propagation axis, wherein the light from one light source can be coupled in at an in-coupling face on one end face of the light guide and the light from the other light source can be coupled in at another in-coupling face on another end face of the light guide. The light guide also has an out-coupling face arranged along the light propagation axis for coupling the light out, which light exits from the light guide at an exit face arranged along the light propagation axis where the total reflection condition is removed. The lighting device according to the invention is characterized in that the light guide is designed in such a manner that the light intensity distribution of the light from at least one light source exiting at the exit face has a gradient in the propagation direction of the light from the light source concerned, and a control device for the light sources (is provided in such a manner that, when the lighting device is switched on, the light sources are activated at a predefined switch-on time interval and thereby the brightness of at least one light source is modified on the basis of a ramped or stepped progression until a predefined brightness value is achieved.

A vehicle lighting unit can increase the light emission region of a light guiding lens to improve the aesthetic feature as the lighting unit when emitting light. The vehicle lighting unit can include an LED serving as a light source and a light guiding lens configured to guide the light from the light emitting element while totally reflect the light which are housed within a lighting chamber defined by a housing and an outer lens that can cover an opening of the housing. The light guiding lens has an aesthetic portion having a rear surface in part of which cuts are formed to cause the light to exit thereby. The aesthetic portion can further have a cut formed in a front surface where no cut is formed in the rear surface thereof.

A light source assembly having N outputs, the assembly including: a light source arrangement arranged for supplying light to M inputs, where M an N independently of each other are integers and where M≥2 and M≥N; at least one optical couplers, each having at least one input arm and a plurality of output arms; and an integer number, P, of mode scramblers. The light source arrangement may include a broadband light source and a multimode coupler configured for receiving one or more light beams from the light source arrangement, wherein the one or more light beams being derived from the broadband light source and wherein a mode scrambler is arranged for mode scrambling one of said light beams before it enters the multimode coupler.

A lighting system for providing a lighting image a first substantially linear lighting structure of at least one lighting component of a plurality of lighting components and a second substantially linear lighting structure of the at least one lighting component of the plurality of lighting components. The first substantially linear lighting structure is configured to appear to intertwine with the second substantially linear lighting structure on at least one cross-over point of a plurality of cross-over points. At least one of the first substantially linear lighting structure appears to overlap the second substantially linear lighting structure at the at least one cross-over point of the plurality of cross-over points and/or the second substantially linear lighting structure appears to overlap the first substantially linear lighting structure at the at least one cross-over point of the plurality of cross-over points.

A lighting module for a vehicle is disclosed. The lighting module comprises a light source configured to generate a light emission in an emission direction substantially along a forward operating direction of the vehicle. A circuit is in connection with the light source. The lighting module further comprises an optic device comprising a body forming a receiving surface. The receiving surface is configured to receive an input emission of the light emission. The optic device is configured to transmit the input emission through the body, emit a first portion of the input emission along a primary path directed toward a passenger compartment of the vehicle, and emit a second portion of the input emission along a stray light path into a light trap formed by the body and arranged substantially opposite the light extraction surface.

A first inclined surface and a second inclined surface are inclined with respect to an optical axis of a light emitting diode. The first inclined surface guides light from the light emitting diode guided in the first light transmitting portion toward an outside of an outer lens. An inclination angle of the second inclined surface with respect to the optical axis is larger than an inclination angle of the first inclined surface with respect to the optical axis. The second inclined surface reflects the light from the light emitting diode guided in the first light transmitting portion toward the second light transmitting portion and guides the light into the second light transmitting portion.

A vehicle grille includes: a grille panel; a lens panel disposed at a rear side of the grille panel, formed in a same shape as some or entire area of the grille panel, and, when a light is incident, configured to allow some of the light to propagate in the lens panel and emit some of the light to an outside of the lens panel; and a housing disposed on a rear surface of the lens panel, formed in a same shape as the lens panel, and including a coupling provision hole configured to allow a front surface of the lens panel to be coupled to a rear surface of the grille panel at a rear side of the lens panel, wherein the rear surface of the lens panel and a front surface of the housing are coupled at the front side of the lens panel.

A vehicle decorative lighting device and a vehicle lamp including the lighting device includes a light guide formed in a nearly ring shape and a pair of light sources that can emit various color lights. Each of the light sources can be located at a respective one of incident surfaces of a lighting body including the light guide. The vehicle lamp can include a lamp room between an outer lens and a casing, and can incorporate various vehicle lamps such as a headlight along with the lighting device in the lamp room. The lighting device can be located in the lamp room so as to emit various color lights while surrounding a vehicle lamp. Thus, the disclosed subject matter can include providing vehicle lamps including the decorative lighting device having a harmonious favorable light distribution, for example, such that combine a headlight with a position lamp with a thin structure.

A light module comprising a means for supporting at least one collector of light rays in the vicinity of which there is a light guide suitable for guiding the rays emitted by a light source from an input face to at least two distinct and adjacent output faces. A distinction is made between a main output face, through which the rays pass in a first direction, and at least one additional output face which is oriented such that the light rays leaving the guide through this additional output face are directed toward the collector, in a second direction distinct from the first direction.
