Abstract: The object of the invention is a structure for locally illuminating a roulette wheel, particularly an automatic or electronic one. The structure consists of a support (4) which in conjunction with a spacer ring (5) forms a slit (9), wherein a band (7) with lamps (8) is mounted. On the inner periphery along the spacer ring (5) there is an optical ring (10). A cover 6is placed over the band (7), the lamps (8), and the ring (10) in such a way as to rigidly fix them.
