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 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.
