Abstract: The invention relates to a pool cover mechanism for winding and unwinding slats over a pool. The pool cover mechanism comprises a tube for connecting with the slats, a tube motor assembly for rotating the tube, a first holder for receiving the non-rotating motor end of the tube motor assembly, an outer shaft bearing assembly connected to the second end of the tube, a second holder for receiving the outer shaft bearing assembly, wherein the outer shaft bearing assembly and the second holder are configured such that at least part of the outer shaft bearing assembly can rotate in the second holder when the tube is tilted compared to the position of the tube wherein the motor end is in the first holder.

Abstract: A lighting for underwater use provides a pool lighting includes a housing with front and back portion enclosing an internal volume. At least part of the front portion is optically transparent. The lighting comprises a PCB with substrate layer, and at least one light source on a substrate layer front side. The PCB is arranged in the internal volume with the front and back side facing towards the front and back portion. The housing is provided with at least one first opening allowing water to enter the internal volume and have contact with the PCB. The at least one light source is sealed off from contact with water. The lighting comprises an optically transparent electrically insulating waterproof first seal covering at least the at least one light source for sealing it off from contact with water. The front portion of the housing is glued against the PCB by means of the first seal.
