A reflector luminaire with a light-emitting means and a reflector, which reflects light from the light-emitting means which is incident on said reflector in a predetermined emission direction and which has a rim () which points towards the emission direction makes it possible to perform particular lighting tasks, for example the uniform illumination of a rectangular illumination area by virtue of the fact that the reflector comprises a plurality of differently designed segments (), which are calculated individually with respect to the light-emitting means for defined illumination of a predetermined area, and by the fact that the segments () are joined to one another by transition sections (), by means of which the predetermined reflecting total surface area of the segments () is reduced by less than &#xbc;.

Reflector luminaire

The invention relates to a reflector, in particular for discharge luminaires, in the case of which at least two facets direct the light from an upper and a lower region of the discharge lamp in the same direction.

Reflector for gas discharge lamps

The optical diffuser has a transparent base body with a base body surface, which is divided into facets. Each facet has an elevation or a depression correlated or associated with a second curved surface. Respective facets have correspondingly different geometrical shapes. In some embodiments the respective apexes (S) of the elevations or depressions are arranged along a spiral, especially an Archimedean spiral. In other embodiments the apexes (S) are defined by coordinates (x', y&#x2032;) derived by rotation of coordinates (x, y) of all points (P), which are defined by an arrangement of facets with regular hexagonal edge contours, about a center (0, 0) through a twist angle (&#x3b4;). Alternatively the apexes (S) are defined by coordinates (x&#x2033;, y&#x2033;) derived from coordinates (x, y) of all points (P), which are defined by the arrangement of facets with regular hexagonal edge contours, by random variations with the help of a Monte Carlo method. The optical diffuser according to the invention produces a circular soft-edged light field, which is outstanding for photographic applications.

Optical diffuser for producing a circular light field

The invention relates to a light reflector comprising a reflective surface having facets at least in sections, and a region for arranging at least one luminous means, wherein facets in a first region, closer to the region for arranging at least one luminous means, the region close to the luminous means, have a cylindrical shape, and facets in a second region, more remote from the region for arranging at least one luminous means, the region remote from the luminous means, have a spherical shape.

The invention comprises an optical arrangement for illumination purposes, in particular for a stepped lens spotlight, comprising a stepped lens with a light-diffusing element, in particular a diffusing screen, in which the diffusing screen is arranged in a first region and the stepped lens is arranged in a second region, and in which, with the change in the shape of the light impinging on the optical arrangement and/or the size of the light illuminating the optical arrangement, it is possible to set the aperture angle of the light emerging from the optical arrangement, in particular between two limit values, a smaller &#x3b1;and a larger &#x3b1;.

Optical arrangement with stepped lens

The optical diffuser has a transparent base body with a first surface, which is divided into facets. Each facet has an elevation or a depression correlated or associated with a second curved surface. Respective facets have correspondingly different geometrical shapes. In some embodiments the respective apexes (S) of the elevations or depressions are arranged along a spiral, especially an Archimedian spiral. In other embodiments the apexes (S) are defined by coordinates (x', y&#x2032;) derived by rotation of coordinates (x, y) of all points (P), which are defined by an arrangement of facets with a regular hexagonal edge contour, about a center (0, 0) through a twist angle (&#x3b4;). Alternatively the apexes (S) are defined by coordinates (x&#x2033;, y&#x2033;) derived from coordinates (x, y) of all points (P), which are defined by the arrangement of facets with the regular hexagonal edge contour, by random variations with the help of a Monte Carlo method. The optical diffuser according to the invention produces a circular soft-edged light field, which is outstanding for photographic applications.

The optical system for the Fresnel lens light has an ellipsoidal reflector (), a light source () and a Fresnel lens (). The distance (a) between the Fresnel lens () and the reflector () is changeable but is related to the changeable distance (b) between the light source () and the reflector () so that the aperture angle of the propagated light beam is variable but illumination intensity of the propagated light is maintained uniform. Surfaces of the at least one Fresnel lens and/or the reflector can be structured to provide more uniform illumination of a given area. The optical system is useful for lights for film, stage, studio and photography.

Optical system for a fresnel lens light, especially for a spotlight or floodlight

The invention relates to a reflector having reflection surface with facets for reflecting light beams and for generating a light field with a hollow basic element which presents a first end for accommodating an illuminant (mounting end), as well as a second end which represents a light outlet aperture, whereby for generating a specific light field contour with a given form of illuminant the forms of individual facets and their position relative to the optical axis of the reflector are selected specifically.
