Abstract: A light emitting apparatus is supported by a second support supported by a first support laterally relative to the first support alongside an imaging apparatus, and emits light to be detected by the imaging apparatus. The light emitting apparatus includes a light source that emits the light and a lens on which the light emitted from the light source is incident and that transmits the light incident on the lens. The lens includes a part provided with a dimmer that at least partially reduces light to be emitted to the first support out of the light incident on the lens.

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.

Abstract: A lighting apparatus includes: a projection lens; a light source behind the projection lens; a reflector that reflects light from the light source toward the projection lens; and a shield that blocks a portion of the light reflected by the reflector to form a cutoff line in a distribution pattern of the light. A textured section demarcated by unit regions is formed on a surface of the projection lens, and when a region in a center of the projection lens is defined as a central region, and regions left and right of the central region are defined as left and right regions, respectively, in a front view, a proportion of the unit regions in the central region is greater than a proportion of the unit regions in each of the left region and the right region.
