摘要: A fan (100) has a fan housing (110). The latter has an air entrance opening (120) and an air exit opening (130). It further has a swivel joint arrangement (180) having at least one swivel joint (145, 147, 155, 157, 165, 167, 175, 177) that is arranged on a joint carrier (188; 188′); at least one non-return flap (140, 150, 160, 170) that is journaled rotatably by means of the at least one swivel joint (145, 147, 155, 157, 165, 167, 175, 177) and, in its closed position, at least partly closes off the air exit opening (130); and at least one elastic return member (142, 152, 162, 172) that is associated with the at least one non-return flap (140, 150, 160, 170) and urges it toward its closed position.

摘要: A testing device (1) for a lamp (3) operated at a nominal voltage (Vn) and at a nominal frequency (fn), having a capacitive coupling of a test voltage (Vp) at a testing frequency of (fp) to the lamp (3), wherein a coupled test voltage (Vpa) corresponds to the nominal voltage (Vn), and a coupled test frequency (fpa) corresponds to the nominal frequency (fn). The testing device is capable of testing a gas-filled lamp having integrated upstream electronics between power supply connections and a gas filled portion.
