Abstract: A lighting device includes: at least one laser light source configured to emit a light beam; and a light conversion element associated with the at least one laser light source and arranged in the beam path of at least one light beam generated by at least one laser light source such that at least a portion of the light beam emitted by the at least one laser light source is directed onto the light conversion element, and in such a way that a laser light spot is illuminated on a face of the light conversion element facing the incident light beam, the light conversion element comprising a material which, through scattering, absorption and conversion of the incident laser light, emits and scatters light of a larger wavelength.

Abstract: An integral homogeneous rod lens and the manufacturing thereof from a raw glass body are provided by melting the raw glass body in a mold, whereby a protruding part of the raw glass body deforms into a dome shape with a spherical or nearly spherical surface that defines a convex lens portion of the rod lens.

Abstract: A hermetically sealed LED light is provided that includes a ceramic base with a plurality of LEDs and a metal cap soldered thereto and a channel for introducing an electrical, optical, or mechanical component.

Abstract: A rod lens and methods for producing such a rod lens are disclosed. The rod lens and methods include a sealing glass and holder glass or a metallic holder that are heated so that only the sealing glass melts and forms a spherical cap to define a lens element joined to a light guiding element. A plurality of rod lenses may form an array arrangement.

Abstract: A reading device, such as a reading lamp or reading spotlight, is provided for use in a vehicle, such as a motor vehicle with immovable properties or ships. The reading device for example can be used in passenger cabins and/or cockpits of aircraft. The reading device includes, but is not limited to an LED light source with a color temperature that can be adjusted with the color “warm-white” to “cold-white”, a primary optics or lens advantageously designed as a converging lens, and a secondary optics or lens to focus the light emitted by the light source onto a surface, such as a reading plane to be illuminated.

Abstract: A mounting structure for at least one LED has a substrate made of silicon and/or another semiconductor, wherein at least one mounting portion formed in a front surface of the substrate for mounting at least one LED chip thereon, and cooling grooves or channels for a cooling fluid are formed in the substrate, preferably in or beneath a rear surface thereof.

Abstract: A light emitting diode (LED) package is disclosed which has an integral reflector for improving performance. The package includes a substrate for supporting the LED. A frame is formed on the top surface of the substrate surrounding the LED. During fabrication, a liquid compound is dispensed into the frame in a manner to surround the LED without covering the active area of the LED. The liquid compound includes particles for scattering light. The top surface of the liquid compound is curved due to surface tension. The curvature remains after the compound is cured. In a preferred embodiment, an encapsulating material is used to cover the LED and the compound. The reflector functions to increase the light output from the LED package.
