Abstract: A lighting device is provided, comprising a spatially extended light source with a light-emitting surface greater than 0.5 mm2 and also an aspherical TIR lens, which is configured to collimate light from the spatially extended light source, and a refractive diffuser configured to generate a lighting distribution on the basis of the collimated light.

Abstract: For the purpose of gas quality monitoring, a spectroscopic examination of a gas sample from a space (10) to be monitored is carried out, e.g. by Raman spectroscopy. The spectroscopic examination yields a measurement spectrum extending over a wavelength range. A deviation of the measurement spectrum from at least one comparison sample (160) is then detected. Depending on the detected deviation, a gas quality warning (QW) is produced.

Abstract: Lighting devices for vehicles, e.g., headlamps or tail lamps, are provided. A refractive diffuser (50) allows the provision of substantially any lighting signature for the lighting device, yielding great freedoms in terms of design.

Abstract: The invention includes an optics array for beam shaping, which uses a micro lens combination, whose polygonal micro lenses are arranged in a level, whereby the geometric arrangement of the individual lenses and their diameters follow a distribution pattern. It is characterized by the fact that the number of corners as well as the length of the lens rims of each of the individual lenses of the micro lens combination is defined by a point distribution (P) of Voronoi points (2), which define a Voronoi Region (VR(p)) which can be described by the following equations for a Voronoi lens (1).
