  • Patent number: 10378715
    Abstract: A solid-state automotive vehicle headlamp includes a solid-state light source (SSLS), a clamshell reflector, and a reflector optic. The clamshell reflector includes a reflective surface defining a clamshell cavity with an open end facing a field to be illuminated. The reflector optic is defined by a portion of a spherical surface in surrounding relation to the SSLC. The reflector optic defines a light-transmissive window permitting a direct line-of-sight transmission of light generated by the SSLC to the reflective surface of the clamshell reflector. The reflector optic further includes a reflective region at least partially surrounding the light-transmissive window and configured to reflect light generated by the SSLC and directed at the reflector optic back towards the SSLC. The reflector optic redirects some of the light emitted by the SSLC through the light-transmissive window towards the clamshell reflector to create a more controlled beam pattern and increase the overall light output.

    Abstract: The present invention provides a lamp device for a vehicle including a light source and an inner lens through which light which is emitted from the light source passes, in which the inner lens includes a lens unit which diffuses light which is emitted from the light source, and a light guiding unit which protrudes toward the light source from the lens unit to guide the light which is emitted from the light source to the lens unit. Light emitted from the light source is guided by the light guiding unit to be incident onto the lens unit and then is irradiated to be diffused to the outside of the vehicle so that the light distribution performance is improved.

  • 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: 8950906
    Abstract: A multi-focal lens for a lighting device includes a central portion and multiple peripheral portions around the central portion. The central portion has a central convex refracting surface, and each peripheral portion has an oblique refracting surface and a convex refracting surface opposite to the oblique refracting surface, wherein the oblique refracting surface extends at an angle with respect to the optical axis of the multi-focal lens. The central portion and the peripheral portions share a common flat surface opposite to the refracting surfaces of the central portion and the peripheral portions. The convex refracting surface and the oblique refracting surface of each peripheral portion can change the paths of corresponding light rays refracted from the flat surface to increase the distance and area of illumination. Furthermore, the volume and thickness of the lens required for a lighting device can be reduced, so that the production cost can be reduced.
