Further disclosed are a vehicle lamp module comprising a dimming mechanism, a vehicle lamp, and a vehicle. The dimming mechanism can achieve the miniaturization of the dimensions of the vehicle lamp module in the second direction, and can improve the precision of dimming in the second direction.

A vehicle lamp is provided, which is capable of changing the clearness of a contrast boundary line correspondingly to a traveling state or a traveling environment of a vehicle. The vehicle lamp is mounted in a vehicle and configured to form a prescribed light distribution pattern including a contrast boundary line, the vehicle lamp including: a sensor provided in the vehicle; and a clearness control unit configured to change clearness of the contrast boundary line correspondingly to a detection result of the 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 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.

An illumination device for a vehicle may include: a light source part; a heat dissipation part mounted on the light source part, and configured to dissipate heat generated from the light source part; a reflector covering the top of the light source part, and configured to reflect the light irradiated from the light source part; a first additional reflector protruding forward from an upper end of the reflector, and configured to reflect the light irradiated from the light source part; a second additional reflector mounted on the heat dissipation part, and configured to reflect the light reflected by the first additional reflector; a shield part configured to pass or block the light reflected by the second additional reflector; and a lens part through which the light reflected by the reflector and the second additional reflector passes.

A light module for a motor vehicle, including a first electrical assembly on a first carrier, which harbours a plurality of branches that are connected in parallel, each branch including light sources, preferably light-emitting diodes. The module includes a second carrier which includes a control unit for controlling the supply of electrical power to the light sources, the control unit including a feedback loop from a reference branch. The light module allows the number of connections between the two carriers of the assembly to be decreased and reliability thereof to be increased.

According to one embodiment, a lighting device for vehicle includes a socket; a light emitting unit which is provided at one end portion of the socket, and includes a light emitting element; an insulating portion which includes a resin, and is provided inside a hole provided in the socket; a power feeding terminal which has conductivity, extends inside the insulating portion, and of which one end portion protrudes from the insulating portion, and is electrically connected to the light emitting unit; and a melting portion which is connected to an inner wall face of the hole, and at least one end face of the insulating portion.

Systems and methods for lighting system lens heating are described. The systems and methods include a substantially clear thermoplastic substrate; and a conductive ink or film circuit on the thermoplastic substrate.

A light emitting arrangement comprises: a plurality of solid state light sources, forming at least one group of light sources, arranged to provide a light distribution comprising a first light portion and a second light portion, and at least one optical component adapted to at least partly collimate light emitted by said light sources, to yield output light exiting the light emitting arrangement comprising central output light and peripheral output light, wherein said central output has a dominant wavelength of 55520 nm and a light intensity of at least 3 cd/m2, and said peripheral output light has a dominant wavelength of 50730 nm and a light intensity of less than 3 cd/m2. The light emitting arrangement thus provides an emission spectrum which is related to the intensity and the direction of emitted light, and can be adapted to enhance the visibility of objects and colors directly beneath the light emitting arrangement as well as at a distance therefrom. The light emitting arrangement is therefore particularly well suited for outdoor illumination at poor ambient light conditions, such as at dawn, dusk, and dark.

A light module includes at least one light source, a light source support, and an optical element suitable for receiving rays emitted by the light source. The optical element includes structure for positioning the optical element in a predefined position on the support and an elastic attachment device for attaching the optical element in the predefined position on the support.

A vehicle light comprising a container body and a lenticular body joined at least partially to close the container body, wherein the container body delimits a containment seat housing at least one light source that faces at least one light guide having a light guide body shaped to receive the light beam from a light input wall, and to transmit it to a light output wall and from this to a main light emission portion of the lenticular body. At least first extractor elements are placed between the light input wall and the light output wall, which extract a first extracted portion of the light beam emitted by the light source and direct it onto first reflecting elements separate from the light guide. The first reflecting elements reflect the first extracted portion towards the lenticular body at a first auxiliary light emission portion, separate from said main emission portion.
