Abstract: A lighting device for a vehicle includes a light source and a linear light emission element for emitting light, which is supplied by the light source via a coupling surface of the light emission element in the light emission element. A light conductor element is provided for distributing and/or directing light, which is supplied by the light emission element in the light conductor element. The light source is linear and is arranged so as to extend parallel to the light emission element so that light from the light source can be coupled to a longitudinal side of the light emission element in an in-coupling surface in the light emission element. The light emission element is arranged at least partially in one side of an open cavity of the light conductor element and force-fittingly and/or form-fittingly held and also can be detached from the light conductor element in a non-destructive manner.

Abstract: The invention relates to an optical arrangement having a division element which divides an input beam consisting of a sequence of temporally equidistant light pulses into two spatially separate partial beams, at least one optical element through which at least one of the partial beams propagates, and at least one combination element which spatially superimposes the partial beams in an output beam. It is the object of the present invention to show a method for increasing the pulse energy of light pulses which is improved in comparison with the prior art. The invention solves this problem by virtue of the fact that the combination element superimposes a number of the temporally successive light pulses in a single light pulse in the output beam. The invention also relates to a method for increasing the pulse energy of light pulses.

Abstract: The invention relates to a fan unit (1) for mobile use for ventilating an area in which it is deployed, in particular for circulating fresh air in areas contaminated by smoke or gases, which comprises a main frame (2), having a lifting frame (4) mounted thereon and an axial fan (3). A first pivot arrangement (8) for the lifting frame (4) is disposed on the one hand in the region of a frame part (7) extending up from a base frame (6) and on the other hand in a first end region (14) of the lifting frame (4) facing the frame part (7). The lifting frame (4) can be adjusted in terms of its vertical distance from the base frame (6) from a non-operating position lying closer thereto into a raised deployment position. A second pivot arrangement (17) is disposed on the lifting frame (4) about which a support frame (19) is mounted so as to be pivotable in terms of its relative position with respect to the base frame (6).
