Summary:A display system comprises an array of spinning LEDs or other light sources comprises a rotary transformer for transferring data signals. A rotary transformer has first and second coils formed on a first planar circuit board and a second coil formed on a second planar circuit board, the second planar circuit board being rotatable with respect to the first. The first and second coils are arranged to be substantially coaxial and separated from one another by a gap. Un système de présentation comprend un ensemble de LED tournantes ou autres sources de lumière comprenant un transformateur rotatif servant à transférer des signaux de données. Un transformateur rotatif comporte des première et deuxième bobines formées sur une première carte de circuit plane et une seconde bobine formée sur une seconde carte de circuit plane, la seconde carte de circuit plane pouvant tourner par rapport à la première. Les première et seconde bobines sont disposées pour être sensiblement coaxiales et séparées l'une de l'autre par un espace.
