An optical light emission system for a motor vehicle, the optical system comprising: a first light emission subsystem comprising a first set of light sources, and a second light emission subsystem comprising a second set of light sources and a light guide able to diffuse the light from said light sources of the second set of light sources outside the optical system. The light guide is arranged facing the first set of light sources such that the first set of light sources substantially radiates through the light guide outside the optical system.

A lightguide functioning as a luminaire. The luminaire includes at least one solid state light source, such as an LED, and a lightguide configured to receive light from the solid state light source. Light from the light source is coupled into the lightguide and transported within it by total internal reflection until the light exits the lightguide. A shape of the lightguide causes and directs extraction of the light, and can also be used to create a particular pattern of the extracted light. Such shapes include linear wedges and twisted wedges. Optical films can be included on the light input and output surfaces of the lightguide.

A fiber structural body includes a first fiber, and a second fiber spliced to the first fiber such that light having propagated through the first fiber propagates through the second fiber. At least one of the fibers is a photonic crystal fiber. The second fiber is coated with a first coating layer and a second coating layer in order from a splice surface, and the first coating layer has a refractive index n.sub.1 larger than that of a clad layer of the second fiber. In the fiber structural body, L, r, n.sub.1, and NA satisfy a particular relationship.

A method and device for emitting electromagnetic radiation at high power using nonpolar or semipolar gallium containing substrates such as GaN, AlN, InN, InGaN, AlGaN, and AlInGaN, is provided. In various embodiments, the laser device includes plural laser emitters emitting green or blue laser light, integrated a substrate.

A cooking appliance including a cooking cavity defined by a cooking cavity wall; a cut out provided in the cooking cavity wall; a cooking appliance light arranged in the cut out and configured to illuminate the cooking cavity; and a support plate including a receiving opening for the cooking appliance light, wherein the cooking appliance light is supported in the receiving opening, wherein the support plate fixes the cooking appliance light in the cut out, wherein the support plate including the cooking appliance light closes the cut out in the cooking cavity wall, wherein the cooking appliance light includes a LED illuminant and a light conductor rod, wherein the light conductor rod is supported in the cut out in the cooking cavity wall.

This disclosure details tie-down systems for securing cargo within vehicle cargo spaces. An exemplary tie-down system may include a vehicle-mounted magnetic assembly and a tie-down that may be magnetically connected to the magnetic assembly for securing cargo within the cargo space. A magnet of the magnetic assembly may be energized to hold the tie-down and cargo in place within the cargo space or de-energized to release the tie-down and the cargo relative to the cargo space.

A lighting device that illuminates textiles by optical waveguides includes a body that receives the optical waveguide; a clamping device for the received optical waveguide; and a lighting module, wherein the lighting module is arranged within the body to enable light emitted by the lighting module during operation to be coupled into the optical waveguide, and the clamping device is adapted to repeatedly clamp and release the optical waveguide.

A method for optically examining or manipulating a microscopic sample includes positioning the sample in front of a lens which is arranged both in an observation beam path and in an illumination beam path of a microscope which has a main beam splitter which separates the paths. An illumination device is selected depending on the type of sample or examination, or a manipulation of the sample to be carried out. The selected illumination device is coupled in a predefined desired position to a mechanical coupling interface of the microscope. An illumination light from the selected illumination device is directed along the illumination beam path to the main beam splitter and from there to the lens and through the lens onto the sample. No optical component for imaging, focusing and/or defocusing is arranged on a light path of the illumination light between the optical apparatus and the lens.

A flexible inside corner trim piece is formed with concave depressions at hinge portions where wings attach to the body. The trim piece can be formed such that wings and a top cap lay flat in plane perpendicular to body or wings and top cap curve at an angle. Hinge portions can be narrow or wide and symmetrical or asymmetrical. The trim piece can be dyed, paintable, or present another decorative surface. The trim piece can include embedded lighting.

A light fixture sign includes a sign message structure including letter-shaped structures. The light fixture sign includes an illumination source to generate light to be projected through a front surface of the letter-shaped structures. The light fixture sign includes at least one reflective mirror having a first surface attached over a back surface of the letter-shaped structures and a reflective surface opposite the first surface to reflect light.
