  • Patent number: 11906123
    Abstract: A light source module is switchable between a high beam and a low beam, and is mounted on a vehicle. A first light source is arranged such that its output light is irradiated to a low-beam region by a first optical system. A second light source is arranged such that its output light is irradiated to a high-beam region by a second optical system. A lighting circuit supplies a driving current to the first light source in response to a turn-on instruction for either the high beam or the low beam. Furthermore, the lighting circuit supplies the output current to the second light source in response to a turn-on instruction for the high beam.

  • Patent number: 11860394
    Abstract: An electronic device may have a display overlapped by an image transport layer such as a coherent fiber bundle or layer of Anderson localization material. The image transport layer may have an input surface that receives an image from the display and a corresponding output surface to which the image is transported. The input surface and output surface may have different shapes. During fabrication of the image transport layer, molding techniques, grinding and polishing techniques, and other processes may be used to deform the image transport layer and the shape of the output surface. To help reduce ambient light reflections and stray light, light-absorbing structures may be incorporated into the image transport layer and other structures overlapping the display.
