    Abstract: A lighting device is provided that includes a light source and an optical element. The light source emits primary light having a primary emission characteristic. The optical element has a light entry face and a light exit face. The optical element includes light guiding elements each forming part of the light entry and exit faces. The light entry faces inject the primary light into the optical element. The light guiding elements each have a boundary surface that totally internally reflects the primary light so that the light exit face emits a secondary light. The optical element reduces a divergence of the primary light such that the secondary light has a secondary emission characteristic with an emission angle (β) that is smaller than an emission angle (α) of the primary emission characteristic. The light exit face is larger than the light entry face.

    Abstract: A method for iteratively reconstructing an input image from an acquired output image generated by transmitting components of the input image by a light guide having unsorted fibers where the output image is detected by an image sensor having a plurality of sensor points includes the steps of: calculating an input image area brightness value for a first area of the input image based on at least a first sensor point brightness value, a first weighting factor, and at least one further input image area brightness; and replacing a first input image area brightness value with the calculated input image area brightness value for subsequent use as the first input image area brightness value. The calculating and replacing are sequentially performed.

    Abstract: A light application device for curing of liquid materials is provided. The device includes a handpiece and a light guiding element which can be mounted to the handpiece and has a light guiding body consisting of a solid body. The light guiding element defines a first optical axis for coupled-in light and a second optical axis for coupled-out light. The second optical axis runs transversely to the first optical axis. The light guiding element has a distal end side at which the coupled-in light can be deflected for coupling out in such a way that the light exit is formed by a region of the lateral surface of the light guiding element. The distal end side has end faces for deflecting the light. The end faces each extend transversely to the first optical axis and transversely to the second optical axis and are connected to one another via intermediate surfaces.

    Abstract: A fiber-optic conversion module is provided as part of a lighting device on a vehicle. The module includes optical fibers with connectors, a light exit head, and a converter mounted on a cooling element. Shorter wavelength excitation light is fed to the optical fibers that emit the excitation light towards the converter arranged at an angle relative to the beam direction, at a light spot that remits useful light in a radiation angle in form of a cone of useful light and reflects excitation light as a Fresnel reflection substantially outside the cone of useful light, where Fresnel reflection is made harmless by a light stop.

    Abstract: A lighting device is provided that has a light source arrangement with a plurality of semiconductor-based light sources in the form of light-emitting diodes. The light sources are bundled or collimated such that they each emit light in differently directed light cones with adjacent light cones overlapping. The lighting device has an adjusting device for adjustment of the direction of illumination and an actuating circuit connected to the adjusting device. The adjusting device adjusts intermediate stages for which the light-emitting diodes of adjacent and overlapping light cones operate and with varying light intensity in such a way the focal point of the light field produced by the light-emitting diodes lies between the focal points of adjacent light cones.
