LED lighting devices are provided that include two optical waveguides and at least one LED in an intermediate region between end faces of the optical waveguides so that radiation from the LED is coupled into the optical waveguides through the end faces. A de-coupler is on outer circumferential surface regions of each of the two separate optical waveguides. The de-coupler reflects the radiation guided in the optical waveguides so that the radiation passes through the optical waveguides and is coupled out of the optical waveguides laterally. The intermediate region has a length that is selected so that a brightness difference, measured perpendicular to an axis of the optical waveguides in the center of the intermediate region, at a distance of 10 mm perpendicular to the axis of the optical waveguides is at most 25% based on a maximum value of brightness along the axis of the optical waveguides.

LED lighting device

The invention provides an illumination device, preferably a reading lamp, which, on the one hand, has a compact design and, on the other hand, ensures a flexible illumination of objects, for which, in order to ensure an adequately high illuminance, high-power light sources can be used and which includes preferably a light source and a light-guiding element that can be pivoted and/or tilted around a pivoting/tilting point, which has at least one light-guiding axis and at least one light in-coupling surface as well as one light out-coupling surface, with the light-guiding element being arranged preferably in an axially displaceable manner in such a way that a free beam area can exist between the light source and the light in-coupling.

Illumination apparatus

A mesh () is placed around a bundle () of fused glass fibers. The bundle is then immersed in a leaching bath (). The ends of the bundle are protected from the bath fluid by furrules (). Some of the glass of the bundle is leached out, so as to provide a flexible fiber bundle.

Method of manufacturing a leached fiber bundle

A method of mounting electro-optical devices on an optical element using an auxiliary substrate is provided herein. Electro-optical fiber optic assemblies are also described herein.
