A vehicle headlight device capable of improving overlooking of pedestrians by a driver. The device includes: a left-side photoirradiator (left-side pattern irradiation lamp) which irradiates light on a left-side light distribution region (irradiation pattern light distribution region) on a left side of a travel roadway of a vehicle in an irradiation pattern in which a bright region a1 and a dark region are alternately repeated; and a right-side photoirradiator (right-side pattern irradiation lamp) which irradiates light on a right-side light distribution region (irradiation pattern light distribution region) on a right side of a travel roadway of the vehicle in an irradiation pattern in which a bright region a1 and a dark region are alternately repeated. In this embodiment, the left-side photoirradiator (left-side pattern irradiation lamp) is illuminated during left turn of the vehicle, and the right-side photoirradiator (right-side pattern irradiation lamp) is illuminated during right turn of the vehicle.

A light-emitting element driving device includes a setter and first to nth constant current sources. An ith series circuit is a series circuit of an ith light-emitting element string and the ith constant current source. The ith constant current source is turned on and off with a delay from an ith dimming signal indicating either lighting or extinction of the ith light-emitting element string. The setter has a mode in which it sets the target value of an output voltage fed to the respective anodes of the first to nth series circuits at a value at which the jth light-emitting element string can be lit during the period from a first time point that a jth dimming signal switches from indicating extinction of the jth light-emitting element string to indicating its lighting to a second time point that the jth constant current source switches from off to on.

A lamp for a vehicle includes a light source unit that generates light and an optical unit for guiding the light. The light source unit includes a plurality of light sources arranged in a matrix shape, and the optical unit includes a plurality of optical members disposed in a traveling direction of the light. The light generated from the plurality of light sources passes through the optical unit to form a beam pattern.

The present disclosure provides a high-precision dimming circuit. A dimming circuit (107) includes an input stage (IN) and an output stage (OUT). The input stage (IN) includes a plurality of amplifiers (AMP1 to AMP3) which have non-inverted input terminals (+) thereof inputted with different dimming input voltages (DCDIM1, DCDIM2 and VH), respectively, and inverted input terminals (−) thereof inputted with a common dimming output voltage (V3). The output stage (OUT) is connected between respective output terminals of the plurality of amplifiers (AMP 1 to AMP3) and an output node of the diming output voltage (V3), and outputs, among the plurality of dimming input voltages (DCDIM1, DCDIM2 and VH) respectively inputted to the plurality of amplifiers (AMP1 to AMP3), a lowest voltage as the dimming output voltage (V3).

A vehicle front lighting apparatus includes a lighting device array in which multiple lighting devices are connected in series, multiple bypass circuits, multiple switch elements, a lighting intensity detector, a lighting schedule generator, a lighting controller, a current value detector, a voltage value controller, a detector, and a disconnection determiner. When there is the switch element to be brought into a closed state during a prohibition period from a lighting timing to a post-lighting timing, the lighting schedule generator changes a timing at which the switch element is brought into the closed state outside the prohibition period. The disconnection determiner determines that a disconnection has occurred in any of the bypass circuits when the number of switch elements detected at the post-lighting timing does not match a voltage value.

Various example embodiments relating to customizing a light profile of a mining vehicle are provided. A user may select which lights of the mining vehicle are activated in different light modes of the mining vehicle. In an embodiment, the user may switch between two or more light profiles. Apparatuses, methods, and computer programs are also provided.

A vehicle having: a vehicle body; a plurality of light-emitting parts; a light source configured to output a laser beam to the light-emitting parts; a fiber optic cable that constitutes a part of a laser beam path, the fiber optic cable having a most upstream branch portion; a single shared laser driver board controlling laser beam source elements in the single light source; and at least one laser light-emission-manner converter, each disposed in, or downstream of, the most upstream branch portion, to thereby cause each light-emitting part downstream from said each light-emission-manner converter to change a light-emission manner thereof. The laser light-emission-manner converter and/or the single shared laser driver board are at least partially disposed in an in-body covered region, which is disposed further downward than, and in a plan view of the vehicle overlaps, any of a fuel tank, a dummy tank, a foot board, and a seat.

The invention relates to a vehicle module (10), including a manipulation-detecting electronic control unit (1), wherein the electronic control unit (1) is equipped in order to control at least one electrically controllable vehicle function, for example a light function, such as a low-beam light function or a high-beam light function.

The present disclosure relates to a lighting device for a motor vehicle having at least one exterior light and a control device. The exterior light has an illuminated area having at least two independently controllable segments, each comprising at least one light source, wherein the control device is designed to operate the exterior light in at least two operating modes, with each of which a geometric manifestation of the exterior light, defined by the light sources operated in the operating mode, is associated such that the total luminous intensity of the exterior light is within a range limited by a minimum value and a maximum value.

A lighting system and a method of operating a lighting module are described. The lighting module includes a heat sink a first LED element mounted on the heat sink emits light as a low beam pattern. A second LED element mounted on the heat sink emits light as a high beam pattern. A driver circuit electrically connected to the first and second LED elements to selectively supply electrical power for operation. The driver circuit is disposed to operate in a first and a second mode. In the first mode, to provide a low beam illumination, the first LED element is operated in a high power state while the second LED element is turned off. In the second mode, to provide a high beam illumination, the second LED element is operated in a high power state, while the first LED element is operated in a dimmed state.
