    Abstract: The invention relates to a projection lens for use in an LED module of a motor vehicle headlamp. The LED module has a light source in the form of an LED matrix including numerous LED chips disposed in a matrix adjacent to and/or above one another, a primary lens including numerous primary lens elements disposed in a matrix adjacent to and/or above one another for bundling light emitted from the light source, and a projection lens. The projection lens projects a light exit surface of the primary lens to generate a predefined light distribution on a surface in front of the vehicle. The projection lens is designed such that it generates at least two separate images of the light exit surface of the primary lens on its image side, which are offset to one another in the horizontal direction.

  • Patent number: 8956027
    Abstract: A projector lens of a vehicular headlamp has a shape of a convex lens in which the upper and lower portions are cut by a predetermined amount. A light source is disposed above optical axis Ax of the projector lens while a light emission surface is inclined downwardly. A first reflecting mirror has an elliptical reflective surface, and is adjusted in size such that almost all the light reflected from the reflective surface is incident on the projector lens. A shield plate is disposed in the vicinity of the focus of the first reflecting mirror to form a horizontal cutoff line. A second reflecting mirror is disposed to reflect light that is not incident on the first reflecting mirror. The third reflecting mirror is disposed above the upper end of the shield plate at a position that does not interfere with the light reflected from the first reflecting mirror.

  • Patent number: 8956029
    Abstract: A vehicle lighting unit can be capable of illuminating pedestrians and the like present in lateral areas above a horizontal line while suppressing generation of glare to oncoming or preceding vehicles. A vehicle lighting unit can also be capable of forming both a basic light distribution pattern and an overhead light distribution pattern without invading an area for reflecting light for forming a basic light distribution pattern. The vehicle lighting unit can include a projector lens disposed on an optical axis, a light source disposed behind a rear-side focal point of the projector lens, a reflecting surface configured to reflect light emitted from the light source so that the light is directed toward the optical axis, and a shade disposed between the projector lens and the light source. The shade can be configured to shield part of light emitted from the light source and reflected by the reflecting surface.

    Abstract: Disclosed is a projection lens that is disposed in front of a first semiconductor light emitting device and configured to irradiate light incident from the rear side to the front side. A first reflector reflects a part of the light emitted from the first semiconductor light emitting device to converge on the rear side of the projection lens. A light guide member is disposed across the front side of the projection lens and configured to emit the light incident from the second semiconductor light emitting device to a predetermined direction. A second reflector reflects a part of the light reflected by the first reflector toward the projection lens. The light reflected by the second reflector to be incident on the projection lens is emitted from the projection to avoid the light guide member.
