The vehicle lamp of the present invention includes: a first light source that emits light for low-beam light distribution; a lens arranged in a front side of the first light source; a shade that is arranged between the first light source and the lens and forms a cut-off line of a low-beam light distribution pattern; a reflector that reflects light from the first light source towards the lens; and a second light source that is arranged between the first light source and the lens and emits light for high-beam additional light distribution. A rear focal point of the lens is located more to a front side than a second focal point which is a focal point on a front side of the reflector, and a lens optical axis of the lens is inclined forward and obliquely downward with respect to a lamp optical axis of the lamp.

The gas guiding device comprises a gas channel and a flow guiding component for guiding an air flow through one or more readily condensable locations of the lighting and/or signaling device.

A vehicle headlamp (1) includes: a light source (52R, 52G, 52B) that emits light having a predetermined wavelength; a light distribution pattern forming optical system (56R, 56G, 56B) that includes a collimator lens (53R, 53G, 53B) and a diffraction grating (54R, 54G, 54B) that change a traveling direction of at least some of pieces of light emitted from the light source (52R, 52G, 52B), and emits light (L.sub.R, L.sub.G, L.sub.B) having a predetermined light distribution pattern; and a vibration imparting unit (57R, 57G, 57B) that relatively vibrates the light source (52R, 52G, 52B) and the diffraction grating (54R, 54G, 54B).

A regulating assembly (1) for a light source and a lighting and/or signaling device, an adjusting device (1200), a lighting device and a motor vehicle, a bezel device (3000), and a gas guiding device and a lighting and/or signaling device containing the same are provided. The regulating assembly (1) and the adjusting device (1200) are used to adjust the lighting and/or signaling module in the lighting device provided in the housing of the lighting device. The bezel device (3000) and the gas guiding device may be used for the lighting and/or signaling device. The regulating assembly (1) comprises a supporting frame (10) coupled in a displaceable manner to the light source, a fixed regulating portion (11) which is rotatable, and horizontal and vertical regulating portions (12,13) in a form of a ball-headed screw-thread part (121). The adjusting device (1200) includes an adjusting screw (1230), a slider (1240) and a base; and the bezel device (3000) includes a top bezel (3100) having a flat plate-like body and a main bezel (3200) including a first bezel (3210) and a second bezel (3220). The gas guiding device comprises a gas channel (5) and a flow guiding component.

A cooling device for cooling a light source located in an automotive luminous device. This cooling device includes a heat sink intended to be in thermal contact with the light source, a plurality of fins in direct thermal contact with the heat sink, a plurality of pins in direct thermal contact with the heat sink and a fan. The fan is arranged to make a fluid flow from an inlet of the cooling device to an outlet to the cooling device, so that the plurality of fins are nearer the inlet than the plurality of pins.

A light source unit includes a card type light source including a card substrate on which a light source is mounted, and a power supply connector configured to supply power to the light source. A card edge connector is formed on a part of the card substrate. The power supply connector is configured to be fitted to the card type light source via the card edge connector. The card type light source is provided with an alignment groove for confirming an alignment state with respect to the power supply connector.

A vehicle lamp includes: a lamp body having a front opening; a front cover attached to the lamp body to cover the front opening and configured to form a lamp chamber with the lamp body; a lamp unit including at least one light emitting element mounting portion having a heat dissipation portion, and disposed in the lamp chamber; an air blower configured to generate, in the lamp chamber, an air circulation flow including a cooling flow sent in a forward direction toward the heat dissipation portion and an intake flow returning to the rear, and an air blower support member configured to support the air blower so as to dispose the air blower behind the lamp unit in the lamp chamber, and to form an intake space through which the intake flow passes below the cooling flow.
