The present invention provides a lamp unit including an optical member, a base assembly disposed to be spaced a predetermined distance from the optical member with a space therebetween, a light source disposed on the base assembly, and a lens coupled to the base assembly to cover the light source, wherein the lens includes a first protrusion having a first contact surface in contact with one surface of the base assembly and a second contact surface formed at a height different from that of the first contact surface to be in contact with the other surface of the base assembly, and a second protrusion having a third contact surface disposed to be spaced apart from the first protrusion and configured to be in contact with the base assembly, and thus may provide an advantageous effect in that the lens is prevented from being shaken on a substrate as well as being moved on or falling off of the substrate.

The invention proposes a lighting device for a motor vehicle. Such a device includes one or more electronic circuits incorporating electronic components sensitive to an electrostatic discharge. Thanks to the features of the invention, the components are protected by encouraging the controlled flow to ground of any electrostatic discharges. All portions of one or more electronic circuits can therefore be protected by preventing random electrostatic discharges liable to destroy or to degrade sensitive electronic components.

A lighting device for a vehicle includes a light source device; a main lens; a reflective fluorescent body configured to reflect and convert wavelengths of incident beams; and a prism arranged between the main lens and the reflective fluorescent body. The prism is configured to: reflect beams emitted from the light source device to be incident on the reflective fluorescent body; and transmit, through the prism and to the main lens, beams reflected from the reflective fluorescent body. The prism includes: a first surface facing the reflective fluorescent body; a second surface through which beams are incident; and a third surface forming an acute angle with the first surface. The prism is configured such that the beams incident through the second surface of the prism form angles of incidence, with respect to the third surface of the prism, that are greater than a critical angle of the prism.

A lighting device for a vehicle includes a lens; a prism that is disposed on a rear side of the lens and that is configured to totally reflect an incident light and to then emit the light; a light source device configured to emit light toward the prism; and a reflective fluorescent body disposed on the rear side of the lens and configured to convert a wavelength of light emitted by the prism and to then reflect the wavelength-converted light to the lens. The prism includes an emitting surface that is spaced apart from an optical axis of the lens. A distance between the reflective fluorescent body and a rear surface of the lens is greater than a distance between the emitting surface of the prism and the rear surface of the lens.

The invention relates to a light module (1) for a motor vehicle or for a motor vehicle headlamp, wherein the light module (1) has at least two or more light sources (10, 11), which are positioned in defined positions relative to one another, and wherein the light module (1) also has two or more reflectors (20, 21), wherein at least one reflector (20, 21) is associated with each light source (10, 11), wherein at least one of the reflectors (20, 21) is movably connected to at least one adjacent reflector (20, 21).

A lamp includes a lamp base unit, a light emitting unit, and a light shape piece. The lamp base unit includes a base seat, a first seat extending from the base seat, and a second seat extending from the first seat. The light emitting unit includes an LED high beam light module disposed on one of the first seat and the second seat, and an LED low beam light module disposed on the other one of the first seat and the second seat and having a light irradiation direction different from that of the LED high beam light module. The light shape piece is disposed on one of the first seat and the second seat for refracting light emitted from a corresponding one of the LED high beam light module and the LED low beam light module to form a light shape having a cut-off line.

The present invention concerns a lighting and/or signaling device (10) for a motor vehicle, said lighting and/or signaling device (10) comprising: a housing (1); an outer lens (3) designed to close the housing (1); at least one light module (5) housed inside said housing (1) comprising: at least one optical surface (9, 9′, 9″); at least one light source (7, 7′) interacting with said optical surface (9, 9′) to form a light beam; a heat sink (11) comprising a plurality of fins (13); an air flow generator (15) designed to generate an air flow (17) towards the heat sink (11), said air flow (17) passing through the fins (13) of the heat sink (11); and a light module holder (19) comprising a front part (20a) oriented toward the outer lens (3) with a plurality of gaps (21) designed to direct the air flow (17) coming from the heat sink (11) towards the outer lens (3).

A vehicle lighting module includes first and second optical units, each having a light source and a light distribution forming portion configured to control an optical path of light emitted from the light source. The first and second optical units are configured to form first and second light distribution patterns in front, respectively. Horizontal illumination widths of the first and second light distribution patterns are substantially equal. Each of the first and second light distribution patterns has a horizontally extending cutoff line at at least a part of an end edge of one of upper and lower sides thereof. The cutoff line of the first light distribution pattern is positioned at the one of the upper and lower sides of the cutoff line of the second light distribution pattern.

There is provided a vehicle lamp including a projection lens, a first light source arranged at a rear of the projection lens and configured to emit light for forming a predetermined light distribution pattern, a reflector configured to reflect the light emitted from the first light source towards the projection lens, a first array light source arranged at the rear of the projection lens and including a plurality of semiconductor light emitting elements aligned in at least one row, and a second array light source arranged at the rear of the projection lens and including a plurality of semiconductor light emitting elements aligned in at least one row. The first array light source and the second array light source are arranged in an upper-lower direction.

A vehicle light optical element (VLOE) comprises a light incident portion, a transmission portion, and a light emitting portion sequentially arranged from back to front. The light incident portion comprises an illuminating light incident structure (ILIS) and at least one high-beam light incident structure (HBLIS), in which an illuminating light incident surface of the ILIS is adapted to receive auxiliary light during low-beam lighting. Alternatively, the light incident portion comprises an ILIS and at least one HBLIS, in which the ILIS is either a flat surface, a curved cylindrical body protruding backwards, a hemispherical body protruding backwards, or a light condensing structure. The ILIS is adapted to receive auxiliary lighting light during low-beam lighting. The ILIS is provided on the VLOE, such that when a vehicle light is in a low-beam lighting mode, the VLOE is also luminous, thereby improving the aesthetic appearance of the vehicle light.
