HEADLAMP UNIT BASED ON PBS
A headlamp unit based on a PBS includes a lens and a beam splitter. Viewed from a reverse light path, parallel light is refracted twice by an incident surface and an emergent surface of the lens and then converged in at least two focuses through the beam splitter. Each focus corresponds to a light path system, and the light path systems may be turned on simultaneously or separately to obtain a corresponding headlamp light pattern. Through beam combination of the PBS, two optical systems may achieve different illumination light shapes through on-off combination of light sources, and the two optical systems do not interfere with each other. The PBS obtains at least two accurate focus positions for the focuses of the lens, and an ideal light pattern may be accurately obtained. An upper beam light pattern may partially cover a lower beam light pattern.

THERMOSET POLYESTER BMC FORMULA FOR DIRECT METALLIZED FORWARD LIGHTING REFLECTOR
A thermoset bulk molding compound useful for making automotive components such as headlamps, as well as other articles of manufacture are described. The composition incorporates moisture absorbing components such as molecular sieves to absorb water present in the compound before molding, thus reducing or eliminating mold defects while retaining the physical properties needed for automotive applications. This results in an as-molded composition with a gloss measured at 60° of greater than 85 GU that can be, without the necessity of a base coat, metallized directly and have reflector quality and durability. The metallized molded components can undergo additional steps such as applying protective sealant layers, as required by the automotive application. The removal of water before molding and the direct metallization reduces the production time of the molded articles.
INTEGRATED LiDAR WITH SCANNING PHOSPHOR ILLUMINATION SYSTEM AND METHOD
A scanning beam system using a rotating platform driven by a motor, and a prism and/or mirror assembly mounted to the rotating platform. In some embodiments, the prism is a square prism. In some embodiments the prism is of polygon shape other than a square. In some embodiments, the mirror assembly is a square mirror assembly. In some embodiments the mirror assembly is of polygon shape other than a square. In some embodiments the mirror assembly includes a plurality of reflective faces, each at a different angle relative to an axis of rotation of the rotating platform.
LIGHT REFLECTING DEVICE, SENSOR DEVICE, AND LIGHTING DEVICE
A light reflecting member has a mirror face adapted to reflect incident light. A first arm member and a second arm member are bonded to the light reflecting member. A first actuator and a second actuator are configured to cause the first arm member and the second arm member respectively to displace in a direction intersecting the mirror face to change an angle of the mirror face relative to the incident light. A thermal expansion coefficient of a material forming the light reflecting member is smaller than a thermal expansion coefficient of a material forming each of the first arm member and the second arm member.
