A light assembly and method for steering a vehicle headlight illumination pattern. In one aspect, a method includes providing a processor programmed to perform the steps of: illuminating a subset of consecutive LEDs in the line including LEDs associated with the first and second edge illumination fields; as the direction of the vehicle wheels changes: (i) fading the LED associated with one of the first and second illumination fields off while simultaneously fading the LED associated with the other of the first and second illumination fields on thereby changing the illumination pattern; and (ii) repeating step (i) so that the illumination pattern tracks the direction of the vehicle wheels.

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.

In a vehicle headlamp control apparatus, a light distribution control section controls light distribution of a headlamp based on a detected light control target object ahead of a vehicle and a detected behavior of the vehicle or an expected change thereof. When the behavior is in a first behavior state in which a change in the headlamp irradiation area becomes equal to or less than a predetermined amount or the behavior is expected not to change from the first behavior state, the light distribution control section causes the headlamp to project light in a standard pattern. When the behavior is in a second behavior state in which the change in the headlamp irradiation area exceeds the predetermined amount or the behavior is expected to change to the second behavior state, the light distribution control section causes the headlamp to project light in a pattern different from the standard pattern.

A light assembly for generating a light pattern comprising LEDs; a first lens positioned in front of the LEDs to direct light from each LED into an illumination field, the illumination fields of energized LEDs create an illumination pattern and a first edge illumination field and a second edge illumination field; a processor controlling the LED duty cycles to move the illumination pattern in a first direction to the side of the first edge illumination field by (i) increasing an LED duty cycle associated with the first edge illumination field while decreasing an LED duty cycle associated with the second edge illumination field; and (ii) repeating step (i) with the illumination field adjacent the first edge illumination field in the first direction as the first edge illumination field and with the illumination field adjacent the second edge illumination field in the first direction as the second edge illumination field.

A message transmission system for a mobility vehicle includesa lighting unit mounted in a steering wheel of the mobility vehicle. Light output is varied according to various traveling situations of the mobility vehicle provide alert to a driver. Accordingly, when an emergency situation occurs during traveling of the mobility, the driver can quickly respond to the emergency situation, thereby ensuring the stability of the traveling mobility vehicle. In addition, the lighting unit mounted in the steering wheel provides an aesthetic appeal to a driver, thereby improving marketability.

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.

A vehicular headlamp driving control device is provided, wherein the vehicular headlamp driving control device comprises: an AFL function on/off check unit; a headlamp driving controller that reads an AFL function execution initiation message and then controls operations of a left/right driving actuator, an up/down driving actuator, and a beam pattern changing actuator, which have been connected to the headlamp, so as to correspond to a sensing value from a sensor; and an AFL function detailed adjustment controller configured such that the AFL function can be distinguished as belonging to an AFL detailed level of an upper level, a middle level, or a lower level according to AFL detailed distinction particulars, which have been preset in AFL function detailed setting particulars, and controlled accordingly.

A lighting device is provided for controlling the photometric distribution of light emitted by two or more LEDs. The lighting device may be integrated with a control system of the vehicle and may be controlled by a remote controller. The lighting device may be capable of being operated in one or more modes of operation based on operating conditions, user input, or both. Operating conditions may include vehicle conditions, environmental conditions, and user conditions. The controller may operate a software application to enable the user to modify, control, or otherwise regulate any mode of operation or other feature of the lighting system.

A control device for a vehicle headlight is a control device that controls radiation of light from the vehicle headlight, and includes a radiation controller that causes the vehicle headlight to radiate pattern light, which includes a first pattern, to a marginal portion that exceeds a portion corresponding to a vehicle width of the vehicle.
