Abstract: A lighting arrangement (1) of a space-saving configuration, including a fluorescent lamp (2) and at least one light emitting diode (6), which is suitable in particular for use for interior lighting of an aircraft. In this case the light emitting diode (6), viewed in the direction of a main lighting direction (13), is arranged behind the fluorescent lamp (2). The lighting arrangement (1) further includes a light guide element (10) which is adapted to guide light (L2) emitted by the light emitting diode (6) past the fluorescent lamp (2) and emit it substantially in the main lighting direction (13).

Abstract: A lighting element with a light emitting device preferably in the form of a light emitting diode, can be fitted in a light carrier. The lighting element has a light-transmissive lens body with a lens-shaped light entry surface and a light exit surface and the light exit surface is smaller than the light entry surface. A starry sky lighting configuration for example in an aircraft cabin, can be implemented with a plurality of such lighting elements.

Abstract: A lighting element has a light emitting diode that is installed in a light carrier. The lighting element has a light guide element that is optically coupled to the light emitting diode and the light guide element has a smaller light exit surface than the light emitting diode.

Abstract: An apparatus for lighting or illuminating spaces, bodies or surfaces, which is formed from a plurality of light emitting diodes (1). The light emitting diodes (1) are radially enclosed by a casing body (14) which is adjoined at the end by a tubular element (15) which bears against a lens (4). A set spacing is thereby established between the light emitting diode (1) and the lens (4). All light spots issuing from the light emitting diode (1) are projected to form a single light spot of a high level of brightness by virtue of the superimposed relationship at a spacing in front of the lens (4).
