Abstract: A method for operating an illumination device as a day travelling light, in particular for automotive vehicles, wherein the device comprises a light source in an illumination housing and a means associated with the light source for bundling the light emitted by the light source, utilizes a light source comprising at least one LED (13).

Abstract: A lamp for vehicles, in particular motor vehicles, has a light source and at least one light-guide arrangement associated with the light source for guiding the light radiated by the light source and coupled into the light-guide arrangement in a specified direction toward an outcoupling point. The lamp further has a light-diverting device in the light-guide arrangement for diverting and/or splitting the light. The light-diverting device is formed as a recess in the light-guide arrangement, and the diversion takes place by means of reflecting the light on one of the lateral surfaces of the recess. The recess is closed by means of a cover element, such that the recess is covered as viewed from the outside of the light-guide arrangement.

Abstract: A swirl disk is composed of at least one metallic material, and is configured as having at least one intake area and at least one outlet orifice, the at least one outlet orifice being introduced in a lower base layer, and having at least two swirl channels emptying into a swirl chamber, the swirl chamber being provided in a central swirl-producing layer. An upper layer is configured as a cover layer, which over its entire cross-sectional surface represents a closed layer without orifice contours. All the layers of the swirl disk are directly built up on top of each other using electroplating metal deposition (multilayer electroplating). The swirl disk is suitable for a use in a fuel injection valve, in particular in a high-pressure injection valve for directly injecting the fuel into a combustion chamber of a mixture-compressing, external-ignition internal combustion engine.
