Abstract: The present invention relates to a sealing device for closing an introduction aperture, the sealing device comprising a fixed support and a shutter mounted movably in translation relative to the support between an extended position and a final retracted position, wherein the sealing device is in a final retracted configuration and wherein the shutter closes introduction aperture. The device includes locking means for preventing any movement of the shutter when it is in the final retracted position. The sealing device further comprises an intermediate retracted configuration, wherein the shutter is at least partly retracted. The sealing device also comprises motion guiding means for guiding the movement of the shutter and designed so that the extension of the shutter is required to move the shutter from the intermediate retracted position to the final retracted position.

Abstract: A lighting assembly, a mounting element and a manufacturing method are described. The lighting assembly includes an LED assembly 20 comprising an LED lighting element 14 provided on a carrier part 12. In order to mount an optical element 50 for forming an emission beam from light emitted from the LED lighting elements 14 a mounting element 30 is provided. The optical element 50 is mounted on the LED assembly 20 by this mounting element 30, which includes mount structure 32, clamps 44 for fixing the optical element 50, a positioning element 34 for positioning on the LED assembly 30 and an alignment part 40. The alignment part 40 comprises a flexible portion 36 and a first fixing part 46. The mount structure 32 comprises a second fixing part 48 movable relative to the first fixing part 46, which is arranged next to the first fixing part 46. The positioning element 34 is positioned on the LED assembly 20. A predetermined alignment may be achieved by fixing the first fixing part 46 to the second fixing part 48.
