    Abstract: The invention relates to a method for producing an optical fibre or an optical coupling-out structure for light comprising a coupling-out surface with light coupling-out structures, by means of an injection-moulding process. The light coupling-out structures are created by the laser removal of the injection-mould material, or the material of the optical fibre or coupling-out element that have already been injection moulded.

    Abstract: In a method of assembling a surface illumination system having an electromagnetic radiation emitting front side, at least one primary radiation source suitable for emitting electromagnetic radiation when operating is disposed on at least one mounting area of a flexible carrier. The flexible carrier has a front side and a back side opposite said front side, the front side of the flexible carrier defines a reference plane. The mounting area of the flexible carrier on which the primary radiation source is disposed is then bent out of the reference plane such that an optical axis of the primary radiation source extends parallel or obliquely to the reference plane. In a further step, at least one light-conducting guide having a radiation emitting front side and at least one incoupling region is disposed on the flexible printed circuit board so that in operation, the primary radiation source emits radiation into the incoupling region of the light guide and the radiation emitting front side of the light guide points in the direction of the radiation emitting front side of the surface illumination system. A corresponding surface illumination system is also described.

    Abstract: A projection apparatus is specified, comprising a light modulator having a light receiving region with a cross-sectional area to be illuminated of the size AM and a maximum acceptance angle α for incident light, and at least one light source by means of which, during its operation, a light cone is produced for illuminating said cross-sectional area of said light receiving region and which comprises a number N of LED chips having a maximum radiation angle &bgr;. At least one of the LED chips has a radiation decoupling area of the size AD. The relation 0.7·(AM·sin2(α))/(AD·sin2(&bgr;)·n2)≦̸N≦̸1.3·(AM·sin2(α))/(AD·sin2(&bgr;)·n2) applies, where n is equal to 1 or to the refractive index of a coupling medium with which the LED chips are provided.

    Abstract: The device has a set of semiconductor light sources (7) e.g. light-emitting diodes, arranged on a carrier (6) e.g. printed circuit board, by using on-board technology, where the light from the sources is coupled to assigned light guides at given angle to surface normals of the carrier. The light guides are provided with reflecting and light emitting surfaces, such that the envelope of the light emitting surfaces forms a curved surface segment. An independent claim is also included for a signal lamp comprising a lighting device.

    Abstract: A lighting device has a light source and optical device subordinating the light source in a radiating direction. Between the light source and the optical device is a primary optical element with a light entrance and a light exit, and is designed so that a specified radiation characteristic corresponding to a radiation characteristic through targeted reflections in the primary optical element and a targeted projection of the light exit or an imaginary surface, is formed by the optical device. An independent claim is included for a primary optical element.
