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: 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 light source unit includes a substrate and a light source. The light source is mounted on the substrate. At least one sensor is configured to detect the infrared light. The at least one sensor detects a wavelength component of the infrared light in a range of wavelengths from 920 nm to 960 nm better than a wavelength component of the infrared light out of the range. The light source device emits the infrared light having a peak wavelength smaller than 920 nm when the light source has a temperature of 25° C. or lower. The peak wavelength of the infrared light emitted from the light source device increases as the temperature of the light source increases from the temperature of 25° C.

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: A light projection lens includes: an inner surface which light emitted from a light source enters, and includes a first concave portion; and an outer surface from which the light exits. In a cross section parallel to an optical axis of the light emitted from the light source, the outer surface and the first concave portion have a difference in radius of curvature in at least a portion of the outer surface and the first concave portion. In a cross section perpendicular to the optical axis of the light emitted from the light source, the first concave portion has an elliptical shape. The light which exits from the outer surface is lesser in amount in an optical axis direction of the light emitted from the light source than in a direction different from the optical axis direction.
