Provided is a vehicular illumination device including a light emitting portion mounted on a headlight, and capable of outputting light from the light emitting portion forwardly of a vehicle with enhanced design and enhanced visibility. An illumination device is provided on a front portion of a vehicle, and includes a headlight, a light guide, and an outer glass. The outer glass is configured such that a perimeter portion and a front surface portion are integrally formed. The perimeter portion includes an incident portion on a middle portion in a length direction of the light guide, the incident portion allowing incidence of light output from the light guide. The light guide is disposed in proximate to the incident portion. Light incident from the light guide to the perimeter portion is guided forwardly, while repeating reflection on inner and outer circumferential surfaces of the perimeter portion, and output forwardly from an output portion formed on the front side.

A device for managing at least two light functions accommodated in a same motor vehicle light device, the managing device comprising a block of light sources for each light function, wherein the managing device further comprises: an input block configured to: provide a power supply common to the at least two light functions; indicate if the at least two light functions are activated or deactivated; a bias block configured to supply a stabilized reference voltage common to the at least two light functions; a switching block for each light function, one switching block of which is configured to deactivate one of the at least two light functions that is defined as secondary with respect to the other of the at least two light functions that is defined as having priority if the latter is activated.

A lighting assembly that provides integrated forward projecting light and side lighting to give a user a broader field of light. The assembly also incorporates daytime running lights to increase visibility during the day and night. The lighting assembly includes a cooling system suitable for dissipating the heat generated by light sources and electrical components of the assembly.

A lighting apparatus includes: a housing; a lens that covers a front surface of the housing; main lighting bodies housed in the housing, the main lighting bodies including left and right two headlights emitting light; a light guide member formed into an -shape to extend continuously along peripheries of the two-headlight main lighting bodies; and an extension that partially covers the light guide member from a front. Light source groups that emit light to be guided to the light guide member are disposed on upper end portions at left and right of the -shape. The light guide member has a center bent portion bent at a position posterior to the extension.

An exterior rearview system for an autonomous vehicle includes a housing adapted for mounting to an exterior side of a vehicle, the housing holding at least one of a reflective element or display screen for displaying to a driver a rear or side image of the vehicle, one or more lighting modules disposed in the housing and providing an adaptive lighting sector which is adaptively controlled, and a control system configured to receive input data related to at least one of a user's intention using a tracking sensor and a user's retaking control of the autonomous vehicle.

A lamp module includes a drive circuit; a first light source; a second light source; and a switching circuit configured to receive a switching signal for indicating switching between a first function and a second function, and to control a first switch and a second switch such that the first switch is in an on state and the second switch is in an off state while the first function is indicated, the first switch is in an off state and the second switch is in an on state while the second function is indicated, and both the first switch and the second switch are in the on states at a time of switching between the first function and the second function.

Provided is an aromatic polycarbonate resin composition that is excellent in terms of hue and thermal yellowing-inhibiting effect and is suitable for light guide members incorporated in automobile lighting devices. The aromatic polycarbonate resin composition comprises: 100 parts by mass of an aromatic polycarbonate resin (A); 0.001 to 0.1 parts by mass of a phosphite stabilizer (B-I) as a phosphorus-based stabilizer (B) having a spiro ring skeleton; 0.01 to 0.5 parts by mass of a phosphite stabilizer (B-II) as a phosphorus-based stabilizer (B) represented by general formula (II) below; 0.05 to 2 parts by mass of a polybutylene glycol compound (C); and 0.0005 to 0.2 parts by mass of an epoxy compound (D). ##STR00001## In the formula (II), R.sup.21 to R.sup.25 each independently represent a hydrogen atom, an aryl group having 6 to 20 carbon atoms, or an alkyl group having 1 to 20 carbon atoms.

A light guide member, and light source groups as light guide member light sources that emit light to be guided to the light guide member, constitute a subsidiary lighting body, and the light guide member is disposed around reflectors. The light source groups are disposed at upper end portions of the light guide member. The light source groups consume electricity more than low-beam light sources and high-beam light sources do. Substrates, on which the light source groups are mounted, are mounted together with heat sinks on a housing main body.

Improved light emitting diode (LED) vehicle headlamps having a dedicated daytime running lamp (DRL) component are described. In various embodiments, a combination Low Beam/DRL headlamp is provided, which uses pulse width modulation (PWM) detection to determine which of the two internal LED light sources (Low Beam or DRL) is powered on. If the Low Beam/DRL headlamp detects a PWM signal on the Low Beam voltage input then it switches to drive the DRL LEDs. If, alternatively, it detects a steady state input voltage then it switches to drive the Low Beam LEDs.

An automotive lighting device, a vehicle and a method for operating an automotive lighting device are described. To economically fulfil different lighting functions the automotive lighting device includes a first and a second lighting unit. The first lighting unit is disposed to emit a first light of a first colour. The second lighting unit is disposed to emit a second light of a second colour different from the first colour. A mixing space is arranged to merge the first light and the second light to a third light of a third colour. The third light is disposed to fulfil a first automotive lighting function and the second light is disposed to fulfil a second automotive lighting function. The first automotive lighting function requires a colour within a first colour range and the second automotive lighting function requires a colour within a second colour range which is different from the first colour range. The third colour is within the first colour range and the second colour is within the second colour range.
