  • Patent number: 10330942
    Abstract: Techniques are described for designing and manufacturing a surface that produces a desired image when illuminated by a light source. As described, the desired image may be decomposed into a collection of Gaussian kernels (referred to as Gaussians). A shape of a micropatch lens corresponding to each Gaussian may be determined, and the resulting micropatch lenses may be assembled to form a highly continuous surface that will cast an approximation of the desired image formed form the sum of a plurality of Gaussian caustics. The disclosed techniques may be used to create a design for a light-redirecting surface amenable to milling (or other manufacturing process).

  • Patent number: 10281100
    Abstract: An optical device comprising: an optical element for converting wavelength formed from a first optical medium having a first refractive index. The converter element receives an incident light beam at a first face and converts it into a converted light beam. The reflective optical element, positioned on a second face of the converter is configured to reflect the converted light beam. The optical device comprises a primary optical element formed from a second optical medium having a second refractive index substantially identical to the first refractive index. A first face of the primary optical element being positioned in proximity to the first face of the converter element, the primary optical element receives the incident light beam and transmits it to the converter. A second face of the primary optical element forms an output face for outputting the converted light beam to minimize parasitic reflections of the converted light beam off itself.

    Abstract: A vehicle lamp device and a light cut-off structure thereof are disclosed. The light cut-off structure includes a front cut-off edge, a rear cut-off edge, and a top surface. The front cut-off edge corresponds in position to the rear cut-off edge and the top surface is connected between the front and rear cut-off edges. A portion of the top surface is inclined along an inclination direction from the front cut-off edge toward the rear cut-off edge. The portion has a predetermined inclination angle relative to a horizontal plane or a lens optical axis. The predetermined inclination angle is greater than 0 degrees and less than 30 degrees. A lighting pattern with a cut-off line is formed when at least one emitted light is selectively shielded by the front cut-off edge. Therefore, the light concentration ratio can be significantly raised.
