Abstract: Systems are provided for an optical device. The optical device comprises a lens actuation system including a motor, a flywheel, a connecting linkage, a plurality of articulating arms, and a lens. The lens is housed in a frame coupled to the articulating arms and driven via the lens actuation system between an upstream position and a downstream position.

Abstract: Systems are provided a coupling system. In one example, the coupling system includes a frame including a plurality of mounts circumferentially arranged along a ring of the frame, and a coupling device engaged with a first mount of the plurality of mounts and a second mount of a second frame. The plurality of mounts and the second mount include rails complementary to recesses of the coupling device.

Abstract: Aspects of sealing of an enclosure are described. In some examples, an enclosure includes a first enclosure piece with a first edge. The first edge includes a first set of edge features. A second enclosure piece with a second edge includes a second set of edge features configured to interlock with the first set of edge features. When the first set of edge features interlock with the second set of edge features, a first projecting feature in the first edge overlaps a gap between a second projecting feature and a third projecting in the second edge.

Abstract: The present invention relates to lens assembly for an illumination device comprising a number of optical lenses and a lens holder comprising a mounting plate having a number of holes, said number of holes being adapted to accommodate said lenses. At least one of said holes is at least partially surrounded by a number of resilient fingers extending backward from the mounting plate, said resilient fingers being adapted to engage with one of said lenses and secure said lens in said holes. The present invention relates also to an illumination device comprising such lens assembly and a method of manufacturing the illumination device.
