A lighting device, which may be employed e.g. as a retrofit bulb for vehicle lamps, includes a light radiation source, e.g. a LED source, and a beam-narrowing optical system facing the light radiation source, for propagating a narrowed light radiation beam of the same source along a longitudinal axis of the device. Arranged distally of the beam-narrowing optical system along said longitudinal axis, there is moreover provided a cascaded arrangement of: a light-condensing lens, a light-driving lens, a filament-like body including annular reflective surfaces extending around the longitudinal axis and exposed to light radiation from the light radiation source propagated through the light-condensing lens and the light-driving lens, a distal mirror member having a reflective surface facing towards the filament-like body, to reflect light radiation towards annular reflective surfaces in said plurality of annular reflective surfaces.

The present invention provides a lamp for a horizontal operating position within a vehicle headlight assembly. The lamp, as seen with respect to the vehicle, comprises a LED light source for emitting light mainly to one side, and a reflective member for shielding front and lower parts of the light emitted by the LED light source and reflecting them to desired directions. The present invention also provides a vehicle headlight assembly comprising such a lamp, and, further, a reflector for shaping the light emitted by the LED light source into a beam, and a shuttle, adjustable between positions to shape the beam into a high beam or a low beam.

In various embodiments, a vehicle lamp is provided. The vehicle lamp includes at least one semiconductor light source, at least one light emission body, and a concentrator arranged between the at least one semiconductor light source and the respective light emission body. A larger light entrance area of the concentrator is separated from the at least one semiconductor light source by a gap. The concentrator at its smaller light exit area transitions into the light emission body. The light emission body has at least one region covered with a partly transmissive layer.

A light source for a vehicle includes a first substrate, a second substrate, a first light emitting element, and a second light emitting element. The second substrate is spaced apart from the first substrate. The first light emitting element is coupled to a surface of the first substrate that faces the second substrate. The first light emitting element is configured to emit light through the second substrate. The second light emitting element is coupled to a surface of the second substrate that faces the first substrate. The second light emitting element is configured to emit light through the first substrate.

The invention relates to a headlight for a vehicle, comprising a concave reflector and a lamp arranged within the reflector to reflect light from the lamp to create an illumination beam with a bright/dark boundary. The lamp comprises a transparent vessel including a longitudinal axis, at least a first and second filament arranged within the vessel. A baffle arranged proximate to the first filament, and comprising first and second upper side edges. The first filament is arranged above a plane including the upper side edges. A different plane is through the center of the first filament and is arranged perpendicular to the longitudinal axis. The upper side edges are arranged symmetrically to a baffle symmetry axis extending from the center of the first filament centrally between the upper side edges. The lamp is arranged within the reflector rotated around said longitudinal axis by a rotation angle of 2-20.

A headlamp assembly includes a housing. A headlamp is disposed within the housing. An image sensor is disposed within the housing and is configured to detect a light source. A controller is operably coupled to the image sensor and the headlamp. The controller is operable to control the headlamp in response to the light source detected by the image sensor.

A lighting device, which may be employed e.g. as a retrofit bulb for vehicle lamps, includes a light radiation source, e.g. a LED source, and a beam-narrowing optical system facing the light radiation source, for propagating a narrowed light radiation beam of the source along a longitudinal axis of the device. Arranged distally of the beam-narrowing optical system along the longitudinal axis, there is provided: a light reflector, a light-driving lens, a filament-like body including annular reflective surfaces extending around the longitudinal axis and exposed to light radiation from the light radiation source propagated through the light reflector and the light-driving lens, a distal mirror member having a reflective surface facing towards the filament-like body, to reflect light radiation towards annular reflective surfaces in the plurality of annular reflective surfaces. The light radiation reflected by the annular reflective surfaces of the filament-like body is spread radially from the longitudinal axis.

A light assembly for a vehicle is provided herein. The light assembly includes a housing and a lens. A light source is disposed between the housing and lens. A bulb shield is disposed between the light source and the lens. A peripheral portion of the bulb shield has a first optical transmittance and a central region of the bulb shield has a second optical transmittance.
