    摘要: A light path processing element, comprising an element main body having a cut-off portion, wherein the element main body is a double-sided reflecting plate, or has a protrusion on one side and a reflecting surface on the other side. A headlamp module, comprising a low-beam illumination unit, a high-beam illumination unit, a collimating optical device, and the light path processing element, wherein light rays emitted by the low-beam illumination unit and the high-beam illumination unit can form low-beam and high-beam light patterns under the action of the light path processing element, and the low-beam and high-beam light patterns can be quickly and noiselessly switched between without needing to move the light path processing element. Further disclosed are a vehicle lamp including the headlamp module, and a vehicle including the vehicle lamp.

    摘要: A lighting device includes: a light source having a light-emitting surface; a reflector having a reflective surface configured to reflect light emitted from the light source; and a lens on which light reflected by the reflective surface is incident. The reflective surface is composed of a portion of a spheroidal surface that includes a first focal point located on the light-emitting surface and a second focal point located between the reflective surface and the lens. The reflective surface intersects a major axis of the spheroidal surface. A value obtained by dividing a first distance, which is a distance between the first focal point and the second focal point, by a second distance, which is a distance between the first focal point and an intersection point of the reflective surface and the major axis, is 7 or greater.

    摘要: A laser-based light source includes a laser device configured to generate laser light of a predetermined laser wavelength and emit this laser light as a laser beam. A light-conversion device is configured to convert at least part of the laser light into converted light and a laser-output sensor is configured to determine a laser-output signal proportional to the output of laser light emitted by the laser device. Further, a converted-light sensor is configured to determine a converted-light signal proportional to the output of converted light emitted by the light-conversion device. A controller is configured to receive the laser-output signal and the converted-light signal, to determine a safe-to-operate parameter, based on the laser-output signal and the converted-light signal, and to control the operation of the laser-based light source based on a comparison of the safe-to-operate parameter with a at least one predefined threshold.
