Abstract:
An optical waveguide (2) for an optical lighting arrangement having a tube (6) arranged at its light exit end, characterized in thatthe tube (6) comprises a non-magnetic material, wherein the optical waveguide (2) has a hand switch for controlling the radiation flow of the optical lighting arrangement, said hand switch being formed by: at least one magnetically activatable switch (27) which is arranged between the optical waveguide (2) and the tube (6) and which is disposed fixedly on the outside peripheral surface of the optical waveguide (2) and which is spaced from the inside surface of the tube (6), and at least one annular magnet (26) which is arranged on the tube (6) and which bears snugly against the tube (6) and which is displaceable axially thereon from an initial position to a switched position in which the magnetically activatable switch (27) is actuated, wherein extending from the magnetically activatable switch (27) are two thin wires or stranded conductors (41, 42) which extend to the light entry end.
