An organic light-emitting diode comprising an organic layer sequence, a radiation exit area and an encapsulation. The organic layer sequence comprises at least one radiation-emitting region which generates electromagnetic radiation in the spectral range from infrared radiation to UV radiation during operation. The radiation exit area is structured, so that the electromagnetic radiation has a directional emission profile. The encapsulation forms a seal of the organic layer sequence against environmental influences.

A water stop switch device includes: a main body, a transmission element and a sealing element; the main body is disposed with a water passage, the sealing element is disposed in the water passage; one end of the sealing element is coupled to the transmission element in transmission way, the sealing element moves in the water passage to open the water passage; the other end of the sealing element and the main body surround to form a chamber; the side wall of the sealing element is disposed with a through hole connecting the water passage and the chamber; when the water passage is open, the chamber is full of water to reduce the pressure difference at two ends of the sealing element.
