  • Patent number: 10164161
    Abstract: A light emitting arrangement is suggested for generating directional projections of light with sharply defined beam profile. Light from a top-emitting solid state light source (12), having reflective side-coating (34), is pre-collimated via a beam-shaping optic (16), before being propagated through a secondary collimating funnel (18), capturing any light rays with still too great an escape angle. Chip-scale package dimensions may be achieved through the use of a thin-film side-coating and undersized phosphor layers. Substrate level process flow further allows for parallel processing of a plurality of devices.

  • Publication number: 20180156411
    Abstract: The present invention relates to a lighting device, in particular a headlamp for vehicles, at least comprising an array of light sources, consisting of first and second light sources being mounted within the same flat or curved plane, and a projecting optical system arranged to project light emitted by the light sources in a forward direction of the lighting device. At least one shifting element is arranged in front of said first light sources. The shifting element generates real or virtual emission positions of the light of said first light sources shifted towards or away from the projecting optical system with respect to emission positions of said second light sources. With the proposed lighting device, in addition to the main lighting function of illumination, a pattern or signature can be projected at one or several additional image planes. The lighting device thus e.g. allows the additional projection of branding or safety patterns.

  • Patent number: 9891429
    Abstract: A controllable polymer actuator (1) comprising a dielectric elastomeric film (2); a first (3) and a second (4) deformable electrode arranged on opposite sides of the dielectric elastomeric film such that application of a voltage between the electrodes causes an active portion (7) of the controllable polymer actuator to change topography. The controllable polymer actuator (1) further comprises a deformation controlling layer (5, 6) connected to the dielectric elastomeric film. The deformation controlling layer at least locally has a higher stiffness than the dielectric elastomeric film, and exhibits a spatially varying stiffness across the active portion (7). This may enable surface topographies that could not at all be achieved using previously known controllable polymer actuators and/or may enable a certain surface topography to be achieved with a simpler electrode pattern and/or fewer individually controllable electrodes.

  • Patent number: 9618739
    Abstract: An actuator comprises an electroactive polymer layer (402) and stretchable electrode structures (410, 411) that are disposed on each side of the electroactive polymer layer (402). A softer passive layer (401) is secured to one of the stretchable electrode structures (410, 411). When compressed transversally by the stretchable electrode structures (410, 411), the electroactive polymer layer (402) will expand tangentially and the actuator will relax into a shape wherein the interior of the electroded region is substantially parallel to the plane of the device, while a substantial portion of the area increase is absorbed by out-of-plane bends arising at the electrode boundary (duck mode). The invention can be embodied as optically reflective or refractive devices with variable geometry.
