Abstract: An illumination device, a headlight, and a movable body are provided which can increase luminosity and resolution at a central region or a peripheral region in an illuminable region. A primary lens is placed at a light emission side of a plurality of light sources, and the primary lens includes a plurality of light guides corresponding in a one-to-one relationship to the plurality of light sources. A size of a light exit surface of a light guide corresponding to a light source which illuminates a central region in the illuminable region of the headlight is set to differ from a size of a light exit surface of a light guide corresponding to a light source which illuminates a peripheral region surrounding the central region.

Abstract: A headlamp that projects light forward includes: a low beam light source module; a reflector disposed in a path of light from the low beam light source module; and a first lens body and second lens body disposed farther forward than the low beam light source module and the reflector. The reflector reflects first light and second light, which are portions of the light from the low beam light source module, toward the first lens body and the second lens body, respectively. The first lens body transmits and projects, to a first region, the first light reflected by the reflector. The second lens body transmits and projects, to a second region larger than the first region and including a region closer to the headlamp than the first region, the second light reflected by the reflector. The first light is higher in luminous intensity than the second light.

Abstract: In a lighting device provided with a light source module including a plurality of light sources, insufficiency of luminous intensity, illuminance unevenness, and the like due to a low-light light source are compensated for. The lighting device includes the light source module which is composed of the plurality of light sources in a matrix and mounted on a board. A drive circuit individually supplies power to the light sources. A processor controls a lighting status of each of the light sources via the drive circuit. The processor determines a low-light light source that is lower in luminous intensity than at least one light source among the plurality of light sources, and causes at least one light source adjacent to the low-light light source to emit light with a higher luminous intensity than the at least one other light source.

Abstract: A lighting apparatus for vehicle use that projects light forward includes a base, a low beam lamp including a low beam light emitter disposed on the base, a first light emitter disposed on the base and a second light emitter. A lighting controller turns on the low beam light emitter, the first light emitter, and the second light emitter, and an optical system reflects light from the first and second light emitters at least above and below the first and second light emitters, to produce a light distribution pattern. Centers of areas illuminated by the light from the first and second light emitters are horizontally spaced from each other.
