The invention relates to an arrangement (1) for the contactless transmission of data between a rotating component and a stationary component by means of light signals which are transmitted by a projector (2) and detected by a receiver (4). According to the invention, a ring-shaped light-conducting body (5) which consists of a transparent material and has integrated reflecting prisms is integrated between the projector (2) and the receiver (4). The exit surface (10) of the light-conducting body (5) opposite the receiver (4) is matt. The projector (2) is allocated to the stationary component and the receiver (4) is allocated to the rotating component This enables light signals to be permanently transmitted from the stationary component to the rotating component, with a high data rate at a high relative speed.
An arrangement for contactless transmission of data between a rotating component and a stationary component by means of light signals emitted by a projector (2, 2a-c) and detected by a receiver (4, 4a-c), wherein between the projector (2, 2a-c) and the receiver (4, 4a-c) an annular light guide body (5, 5a) of a transparent material with integrated reflection prisms (12) is integrated and wherein the exit surface (10, 10a) of the light guide body (5, 5a) opposite the receiver (4, 4a-c) has a matte finish, wherein shells (11) are formed as a unitary part on the circumference of the light guide body (5a), which shells are matched to the number of the light guides (17, 17a-c;
