摘要： Whereas incandescent light bulbs and other similar light sources known in the related art emit light in all directions, LED lamps can emit light in a single direction, and this is manifested in the problem of being unable to achieve light distribution characteristics satisfied by conventional headlamp designs. In accordance with an embodiment of the disclosed subject matter, an LED lamp for a light source of a headlamp can include an LED chip in the vicinity of the focus of a projection means and a shielding member covering a portion of the LED chip in a formation allowing a light distribution characteristic suitable for a vehicle front-illumination light to be obtained when light from the LED chip is magnified and projected in an illumination direction by a projection lens or the like constituting the projection means. Accordingly, accurate light distribution characteristics can be obtained in a simple manner by projecting in the illumination direction using the projection lens.

摘要： A light, and particularly a vehicle light, can prevent a reflected image of a resin injection trace (reflected in an adjacent connecting surface surrounding a reflecting surface) from being observed through a projecting surface, thereby preventing deterioration of appearance of the light. The light can include a light source and a lens body having a resin injection trace by injection molding. The lens body can include, as its surface, optical surfaces including an incident surface, a reflecting surface, and a projecting surface that are configured to form a predetermined light distribution pattern. Connecting surfaces that shape and define a structure of the lens body can connect the optical surfaces, and can be configured so as not to engage in the formation of the light distribution pattern. The incident surface can be a lens surface that can receive light from the light source to allow the light to enter the lens body. The reflecting surface can reflect the light from the light source toward the projecting surface so as to form the light distribution pattern. The projecting surface can be a lens surface that can receive the light directly from the light source and the light reflected by the reflecting surface, and project the same. The adjacent connecting surface of the connecting surfaces can be configured so as not to generate a light path from the resin injection trace via the connecting surface to the projecting surface.

摘要： The disclosed subject matter includes a projector headlight using a plurality of optical units for a low beam with a high visible/visual quality. Each of the optical units can include a plurality of LED devices and a projector lens. The projector lens can include a light-emitting surface including a reflex function and a reflex surface including a light incoming surface that is located on the opposite side of the light-emitting surface. The LED devices can be located adjacent the light incoming surface, and the optical units can be located so that angles between optical axes of adjacent optical units can become substantially a same angle. Thus, the projector headlight can form various favorable light distribution patterns by changing curvature factors of the light-emitting surface and the reflex surface of the projector lens in each of the optical units and by changing the angles between the optical axes of the adjacent optical units.
