Markus STUHLDREHER has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11746984
    Abstract: An illuminating device for vehicles, including an elongated light guide, which has an end face for coupling light into the light guide and has a lateral surface, at which the coupled-in light may be totally reflected in a coupling direction. An elongated reflector is arranged so that it follows the light guide and at least partially behind the light guide in the main emission direction. The light guide is designed such that the coupled-in light is coupled out on a rear-side lateral surface and/or side lateral surface facing the reflector and on a front lateral surface facing away from the reflector. The light guide and the reflector each have a corner region, in which sections of the light guide and sections of the reflector enclose an acute or right or obtuse angle.

  • Patent number: 10732345
    Abstract: A light guide for a lighting device, wherein the light guide extends along a longitudinal axis and has a coupling-out area which runs over the longitudinal axis and from which light can be emitted along the longitudinal axis, and wherein the light guide has, in its longitudinal extent, an end region which is provided with a cover in order to suppress high-intensity light emission in the end region. The cover is formed by laser-machining the light guide material in the end region of the light guide. The invention further relates to a method for forming a cover in the end region of the light guide.
