Abstract:
An optical switch (14) is provided that switches between a wash mode and a beam mode. A set of two parallel lenticular lenses (16, 18) with the same focal length are separated by a first distance (24) and are configured to adopt a beam configuration and a wash configuration. In the beam configuration, the parallel lenticular lenses are aligned along an identical axis such that the optical power of the set of lenticular lenses is approximately zero. In the wash configuration, one of the two parallel lenticular lenses is rotated with respect to the other parallel lenticular lenses.
Abstract:
Described are improved automated luminaire and luminaire systems employing an articulated elongated light homogenizer the articulation of which allows for the homogenizer to be remotely selectable by the user whereby the articulation inserts the homogenizer into the light path in the light engine or removes the homogenizer from said light path.
Abstract:
Described are an improved automated luminaire (12) and luminaire systems (10) employing an improved output lens system (30) and carrier (32). The output lens (30) may be extended along the optical axis outside the frontal confines of the chassis of the luminaire in order to provide an improved narrow angle performance from the optical systems.
Abstract:
A method of making an illuminated panel for projecting a pattern or an image and for use with a lighting system including a light source includes the step of providing a substrate. The method further includes the step of printing at least one layer of ink on the substrate to create an image or pattern that may be projected onto a surface, wherein the at least one layer of ink is a light absorbent or light reflective layer of ink that protects the substrate and ink from light energy, ultraviolet light, and infra-red energy.

Abstract:
The present invention relates to a light collector for an illumination device collecting light from a plurality of light sources and combing the collected light into a common light beam, where the common light beam is coupled through an optical gate. The light sources are distributed offset and around an optical axis and the light beam collector comprises a first reflector surrounding the optical axis and a second reflector surrounding the optical axis, where the first reflector reflects the sources light beams towards the second reflector and where the second reflector reflects the source light beams in a direction along the optical axis. The light beam collectors is divided into a number of reflector pairs, where each reflector pair comprises a first surface part of the first reflector and a second surface part of the second reflector, where the second surface part receives light from the corresponding first surface part of the reflector pair.
Abstract:
A gobo arrangement (200, 300, 400) comprises a first gobo holder (210, 310, 410) arranged to rotate around a first rotational axis (211, 311, 411), a second gobo holder (220, 320, 420) arranged to rotate around a second rotational axis (221, 321, 421) spaced apart from the first rotational axis, and a light receiving region (240, 340, 440) spanning between the first and second rotational axes. The gobo arrangement further comprises a set of at least two gobos (230, 330, 430) mounted to the gobo holders such that each one of the gobos is allowed to be exposed in the light receiving region. The present invention is advantageous in that the gobo arrangement has a reduced size.

Abstract:
The present invention relates to an illumination device comprising a number of light sources and a number light collecting means, where the light collecting means collect light generated by the first light sources and convert the light into a source light beam propagating primarily along a primary optical axis. At least one light modifier is positioned along the primary optical axis and reflect at least a part of the light. A first light source comprises a light converting material capable of converting light into longer wavelengths and a second light source generates light having at least one spectral component which can be converted by the converting material of the first light source. The first and said second light source are mutually positioned in relation to the primary optical axis such that at least a part of a the second source light beam hits the first light source after being reflected by said light modifier.
