A lighting device includes: a light source having a light-emitting surface; a reflector having a reflective surface configured to reflect light emitted from the light source; and a lens on which light reflected by the reflective surface is incident. The reflective surface is composed of a portion of a spheroidal surface that includes a first focal point located on the light-emitting surface and a second focal point located between the reflective surface and the lens. The reflective surface intersects a major axis of the spheroidal surface.

A steerable lighting and/or optical device for a vehicle. A light source transmits a light beam to a rotating mirror which scans or points the light transversely ahead of the vehicle to create a desired beam shape. An intensity of the light source may be modulated during sweeping, including modulation to zero intensity, to control the pattern of light generated by the sweeping beam.

A vehicle lamp includes: a light source that emits a light; an optical member including a lens that irradiates the light from the light source to a front of the vehicle lamp and forms a predetermined light distribution pattern including a plurality of regions; and a controller that, when an object outside the vehicle is detected, adjusts the predetermined light distribution pattern so as not to irradiate at least one first region including the object among the plurality of regions with the light. When the vehicle body is in a cornering state, the controller acquires inclination information of the vehicle body, determines whether there is a second region that does not exceed a reference line, based on the inclination information, and when determining that there is the second region, irradiates the second region with the light even when the object is included in the second region.
