A vehicle light includes a lighting unit with multiple light-emitting elements (LEEs), one or more couplers, a light guide and an extractor. The lighting unit has a curved elongate extension. Each of the couplers has an input aperture coupled with one or more of the LEEs and an exit aperture coupled with a first edge of the light guide and is configured to couple light from the LEEs into the light guide. The light guide is configured to propagate light via total internal reflection to a second edge of the light guide. The extractor has an input aperture coupled with the second edge of the light guide and an exit aperture configured to emit light into an ambient environment.

A lighting device including at least two LED light sources configured for individual activation; at least two light guides arranged adjacent to one another, each including an edge surface facing a respective one of the LED light sources, a back surface extending from the edge surface provided with a plurality of diffuser extractor elements, and a front surface extending from the edge surface and opposite the back surface; and opaque barrier walls provided between the at least two light guides and extending from the rear wall to the front wall, to mechanically and optically separate the light guides. The light guides are configured to receive light from the LED light sources, with the diffuser extractor elements arranged shaped redirect received light traveling within the light guide to be projected through the front surface.

A head lamp module for a vehicle is provided. The head lamp module includes a shield that is configured to be rotated by operations of first and second solenoids and first and second shield operation mechanisms and a beam pattern of a low beam mode, a beam pattern of a high beam mode, or a beam pattern of an ADB mode that is implemented based on a rotation angle of the shield. The beam pattern of the low beam mode is implemented when a fail safe function is performed based on a failure occurrence in the high beam mode or ADB mode state.

The present disclosure provides a vehicle lamp including: a main bracket pivotably supported to a lamp body; and a sub-bracket pivotably supported to the main bracket. A first optical unit is supported directly to the main bracket, and three second optical units are supported to the main bracket via the sub-bracket. An optical axis adjustment for the first optical unit and the three second optical units is collectively performed by pivoting of the main bracket, and an optical axis deviation between the first optical unit and the three second optical units is corrected by pivoting of the sub-bracket.

A vehicle lamp system includes a vehicle lamp, a first imaging device structured to be disposed outside a lamp room, and generate a first image, a second imaging device structured to be housed in the lamp room, and generate a second image, and a light distribution control device. The light distribution control device includes an information processor structured to acquire from an outside or generate information of a first light shielding part, and decide a second light shielding part, a control executer structured to execute light distribution control for forming a light distribution pattern including the second light shielding part, and a control regulator structured to control the vehicle lamp to form a light distribution pattern including the first light shielding part when at least one condition of a condition (i) to a condition (iv).

A vehicle lamp includes a light source unit including a plurality of light emitting units for forming different beam patterns, and an optical unit disposed in front of the light source unit for transmitting light generated from the light source unit to form a predetermined beam pattern. The plurality of light emitting units includes a first light emitting unit for forming a first beam pattern and a second light emitting unit disposed around the first light emitting unit for forming a second beam pattern different from the first beam pattern.

A blade receives light emitted from a light source and repeats a predetermined periodic motion to scan the front of a vehicle with reflected light of the emitted light. A position detector generates a position detection signal S4 indicating a timing at which a predetermined reference point of the blade passes a predetermined position. Based on the position detection signal S4, a period calculator calculates a period Tp of the periodic motion of the blade. A light intensity calculator receives light-distribution-pattern information S3 to be formed in front of the vehicle and calculates light intensity to be generated by the light source at each time based on the position detection signal S4 and the period Tp. A driver turns on a semiconductor light source so as to obtain the light intensity calculated by the light intensity calculator at each time.

Three lamp units are supported on a bracket supported to be rotatable with respect to a lamp body. In the configuration of the respective lamp units, light source units are supported to be rotatable in an up and down direction with respect to the bracket, and projection lenses are fixedly supported on the bracket. Accordingly, it is possible to correct a misalignment of optical axes among the lamp units by preventing the occurrence of the positional misalignment of the projection lenses among the lamp units and then rotating the respective light source units with respect to the bracket.

A vehicle lamp comprises a first light source group for forward illumination comprising at least one light emitting element, a second light source group for road surface drawing comprising at least one light emitting element provided separately from the at least one light emitting element, a single projection lens through which lights emitted from the first and second light source groups are to pass, and a light shade arranged between the first and second light source groups and the projection lens so that the light from the first light source group and the light from the second light source group do not intersect with each other before entering the projection lens. The projection lens has a first region through which the light from the first light source group is to pass and a second region through which the light from the second light source group is to pass.

In various embodiments, a retrofit lamp for vehicle headlight is provided. The retrofit lamp includes at least one semiconductor light source, a plurality of light output coupling optical units, and a light-guide apparatus which is embodied to guide light from the at least one semiconductor light source to the light output coupling optical units. The light-guide apparatus includes at least one light-exit end, at which the light output coupling optical units are arranged spaced apart from one another.
