Aspects and embodiments disclosed herein include an illumination apparatus comprising an LED light generating device comprising groups of LEDs spatially distributed on an emission surface for the generation of light, the generated light being emitted from the emission surface of the LED light generating device through a transparent and resistant protective screen of the LED light generating device, and comprising a replaceable light shaping device mounted in front of the transparent protective screen of the LED light generating device for shaping the light emitted from the emission surface of the LED light generating device.

Illumination apparatus

A medical light () has an illumination unit () having lighting means () and optical means () for generating a light field (), wherein the lighting means () are formed by an essentially punctiform LED light source () and the optical means () have a plate-shaped collimator () and a cover pane (). The collimator () has a central area (), which is provided with light-refracting structures () on a side facing away from the LED light source (), and an outer area (), which is provided with structures () designed for total reflection on a side facing toward the LED light source (), wherein the cover pane () is provided with a lens structure, which has a plurality of individual lenses which each project the light emitted by the collimator () onto the object plane. The rear side of the central area of the collimator facing toward the LED light source is provided with partial surfaces (), which have an inclination in relation to a plane (E) of the collimator (), in order to asymmetrically expand the light field () in one direction.

Medical light

Spotlight () for illuminating a film, studio, stage, event and/or theatre environment, comprising: a light space () having an optical axis () which defines a light output direction; a light source () which is disposed in the light space (); a housing () which delimits the light space () and extends in the light output direction; a main reflector () which delimits the light space, extends transversely with respect to the light output direction and, relative to the light output direction, is disposed upstream of the light source (); an output optical unit () which is disposed at a light exit side of the light space () and, relative to the light output direction, is disposed downstream of the light source () and outputs the light of the spotlight (); an auxiliary reflector (), wherein the auxiliary reflector () is disposed movably, such that it can be positioned at least at a first position between the main reflector () and the light source () or at a second position between the light source () and the output optical unit ().

Spotlight

A light-producing assembly for a spotlight for illuminating film, studio, stage, event and/or theater surroundings comprises a carrier, on which an LED arrangement with a multiplicity of LEDs is arranged. Here, the LEDs are provided by N&#x3e;2 different color types. The assembly also comprises a line system for supplying power to the LEDs, which comprises a multiplicity of lines with N line types, wherein lines of different line types cross in crossing regions and the crossing regions lie outside of a vertical projection surface of footprint sides of the LEDs in a vertical plan view of the carrier front side. Further, the assembly comprises an optical unit coupled to the LED arrangement, said optical unit spanning the totality of the LEDs. Moreover, a spotlight comprises such a light-producing assembly.

Light-producing assembly for a spotlight and spotlight

A spinal cannula with a needle hub having a transparent area for observing the liquor flowing through a hollow cavity of the needle hub. A structure for refracting or reflecting rays of light is provided in or at the transparent area of the needle hub. The structure for refracting or reflecting rays of light may be formed as one or more prisms.

Spinal cannula having liquor detection

A projector having a lamp and a reflector that reflects the light beams emitted by the lamp toward a light exit opening of the projector is provided. It is possible to vary the position of the reflector and of the lamp relative to one another, and to set the distribution of the exiting light by displacing the reflector and/or the lamp. The reflector is provided with facets that form a reflective surface for reflecting the light beams emitted by the lamp. The facets being constituted by their surface shaping such that the light beams generate a light field with a desired light distribution and whose light beam width can be set in a wide range by displacing the reflector and/or the lamp.
