A light projection method for a moving body which is performed by a processor of the moving body is provided. The method comprises: irradiating light from a light source of the moving body; scanning the light irradiated from the light source with an angle range that is formed by swing a mirror portion of an optical scanner of the moving body; acquiring change information of the angle range at which the mirror portion swings; changing the angle range at which the mirror portion swings based on the acquired change information; and changing an irradiation range of the light irradiated from the light source.

A vehicle lamp includes: a light source; an optical member configured to form a predetermined light distribution pattern by radiating light; and a controller configured to adjust the predetermined light distribution pattern so as to include a first non-irradiation range in which an object outside a vehicle is not irradiated with the light when the object is detected. The controller is configured to define the first non-irradiation range based on a case where a vehicle body is in a straight traveling state. When the vehicle body is in a cornering state, the controller is configured to acquire height information of the object in accordance with a tilting state of the vehicle body, define a second non-irradiation range narrower than the first non-irradiation range based on the height information, and adjust the predetermined light distribution pattern so as to include the second non-irradiation range instead of the first non-irradiation range.

An adaptive illuminating headlight is provided. The adaptive illuminating headlight includes a stator structure, a rotor structure, a driver, a light emitting unit, an optical assembly, and a control unit, and is installed on a vehicle for use. The rotor structure is configured to rotate relative to the stator structure and has a carrying surface. The driver is arranged between the stator structure and the rotor structure to drive the rotor structure. The light emitting unit is arranged on the carrying surface to emit an illumination light beam. The optical assembly is configured to allow the illumination light beam to project outwardly so as to produce an illumination pattern. The control unit is configured to control the driver to operate according to a posture change of a vehicle body, such that the light emitting unit is driven by the rotor structure to rotate through a predetermined angle.

A light distribution control device can perform diffused light distribution control designed to widen an irradiation range of a headlamp of an own vehicle. The light distribution control device is equipped with a recognition unit that recognizes a situation around the own vehicle, and a control unit that performs diffused light distribution control when a curve section in front of the own vehicle in a traveling direction thereof is detected, from a result of recognition by the recognition unit. The control unit controls the headlamp such that a non-required irradiation region where irradiation with light is not required is restrained from being irradiated with light and that a region other than the non-required irradiation region is irradiated with more light, when the non-required irradiation region is detected in the irradiation range of the headlamp in performing diffused light distribution control, from the result of recognition.

A vehicle comprises a first lighting assembly disposed to the left of a longitudinal axis of the vehicle and comprising a first array of independently operable light emitting diodes and a first projection lens arranged to form a front left light beam for the vehicle from light output from the first array of light emitting diodes, a second lighting assembly disposed to the right of the longitudinal axis of the vehicle and comprising a second array of independently operable light emitting diodes and a second projection lens arranged to form a front right light beam for the vehicle from the second array of light emitting diodes, and a controller configured to control activation of the light emitting diodes in the first array of light emitting diodes to adjust an angle between the front left light beam and the longitudinal axis of the vehicle and to control activation of the light emitting diodes in the second array of light emitting diodes to adjust an angle between the front right light beam and the longitudinal axis of the vehicle.

A headlight device includes an optical unit to emit light and a support mechanism to support the optical unit.
