Abstract: A lighting device that may be independent or may be one of a set that includes a plurality of lighting devices. The lighting device may be a Christmas tree-topper device, that may be placed on top of a supporting body, such as the top of a Christmas tree. The lighting device includes a light-emitting element and an electrical current source which is independent of an electrical network and supplies power to the light-emitting element. The lighting device may also include a housing that includes an upper housing portion extending upwardly towards an end at which the light-emitting element is situated, the housing also including a lower housing portion that supports the electrical current source. The lighting device may also include a sleeve for receiving the top of the supporting body, the sleeve having an opening at its bottom end.

Abstract: A set that includes a plurality of the lighting devices, each lighting device including a body having a light-emitting element, an attachment element for attaching the lighting device to a supporting body, and an independent power source for supplying power to the light-emitting element. The set also includes a wireless transmitting device configured to turn on and off the light-emitting elements of each one of the plurality of lighting devices. The wireless transmitting device may be integrated in one of the plurality of lighting devices. The wireless transmitting device may be disposed in a remote control unit that is separate from each one of the plurality of lighting devices.

Abstract: A drinking container in which a tube is movable between a closed sealing position and an open drinking position. The tube and the bottom of the container, when in the closed sealing position, are sealed by a closing element. The closing element, when in the open drinking position, uncovers the interior of the tube in such a way that liquid can be withdrawn from the receiving chamber via the tube.

Abstract: A lighting device in which the current source is arranged at a spatial distance from the lighting body. The weight of the lighting body may be reduced accordingly, thereby increasing the stability of the lighting body when fastened to a supporting body.
