A vehicle display system provided to a vehicle, includes a first display device, a second display device, and a display control unit. The first display device is configured to emit a light pattern toward a road surface outside the vehicle. The second display device is located inside the vehicle and configured to display predetermined information toward a passenger in the vehicle so that the predetermined information is superimposed on a real space outside the vehicle. The display control unit is configured to control the first display device. The display control unit is configured to control emission of the light pattern according to a passenger's input operation on a display area where the predetermined information can be displayed.

Provided is a light source drive device including: a current supply device; and a light source device including a light emitting element that emits light by receiving drive current supplied from the current supply device, a temperature sensor that performs temperature detection at a position closer to the light emitting element than the current supply device, and a signal generation unit that outputs a control signal for controlling the drive current depending on a detected value of the temperature sensor to the current supply device. The signal generation unit generates a control signal for reducing the drive current depending on a temperature when the temperature detected by the temperature sensor is equal to or higher than a predetermined temperature.

A laser head lamp for a vehicle includes: a plurality of lamp modules each comprising a laser diode and configured to output at least one of a low beam or a high beam; at least one processor; and a computer-readable medium coupled to the at least one processor having stored thereon instructions which, when executed by the at least one processor, causes the at least one processor to perform operations comprising: acquiring total operation time of each of the plurality of lamp modules; and controlling, based on the acquired total operation times, at least one first lamp module among the plurality of lamp modules differently from at least one second lamp module among the plurality of lamp modules.

The invention relates to a method for operating a first and a second light-emitting unit of a motor vehicle. A first voltage converter is provided for operating the first light-emitting unit. A second voltage converter is provided for operating the second light-emitting unit. A switching unit is arranged between the two light-emitting units and the voltage converters, such that the second voltage converter is connected to the first light-emitting unit.

A lighting method comprising: definition, by a control system (CTRL_S) of a lighting device (HL), of a parameter (PAR) of the lighting device; transmission of this parameter, by the control system, to an actuator (LSS) of the lighting device; and generation, by the actuator, with a light source (LSR) of the lighting device, of a light beam producing an image corresponding to a light map obtained by modifying a light map stored in the actuator using the parameter received from the control system. The description also relates to a lighting device, a computer program and a storage medium for implementing such a method.

This display system which is provided in a vehicle comprises: a road surface drawing device that is configured so as to emit a light pattern (L1) toward a road surface outside the vehicle; an HUD that is located inside the vehicle and configured so as to display HUD information to an occupant of the vehicle such that the HUD information is overlaid on real space outside the vehicle; and a display control unit that is configured so as to control the road surface drawing device. The display control unit is configured so as to control the emission of the light pattern (L1) in accordance with an input operation by the occupant in an HUD display area (D1) where the HUD information can be displayed.

In a lighting device, when determining that both of a first measuring value and a second measuring value are not an abnormal value, a controller is configured to control an output of a power converter based on the first and second measuring values. The first measuring value is a temperature inside a main body of the lighting device, sensed by a first temperature sensor. The second measuring value is a temperature of a light source, sensed by a second temperature sensor. When determining that at least one of the first and second measuring values is the abnormal value, the controller is configured to control the output of the power converter to another value that is different from a value of the output set based on the first and second measuring values.

An abnormality detection device includes a load connected to a load connection terminal; a first switching element, having one end connected to the load connection terminal, that switches between connection and disconnection of a power supply to the load; a control unit that switches between an on state and an off state of the first switching element; a detection unit that outputs a signal based on comparison between a voltage of the load connection terminal and a predetermined reference voltage; an acquisition unit that acquires the signal from the detection unit; a determination unit that determines that the load is in an abnormal state when the acquisition unit acquires an abnormality detection signal, which is a signal of a predetermined level, continuously for more than a predetermined first determination time period after the control unit switches the first switching element from the on state to the off state.

The present disclosure relates to a lamp for a vehicle, and more particularly, to a lamp for a vehicle which is capable of preventing occurrence of a blind zone caused by a defect. The lamp includes a light source portion with a plurality of light emitting areas in which brightness of generated light is separately controllable and a brightness controller which is configured to cause the plurality of light emitting areas to generate light at a first brightness level to form a beam pattern and to cause at least one of the light emitting areas, which is disposed proximate to a defective area which includes at least one faulty area, to generate light at a second brightness level.

A laser head lamp for a vehicle includes: a plurality of lamp modules each comprising a laser diode and configured to output at least one of a low beam or a high beam; at least one processor; and a computer-readable medium coupled to the at least one processor having stored thereon instructions which, when executed by the at least one processor, causes the at least one processor to perform operations comprising: acquiring total operation time of each of the plurality of lamp modules; and controlling, based on the acquired total operation times, at least one first lamp module among the plurality of lamp modules differently from at least one second lamp module among the plurality of lamp modules.
