Claim:
A variable configuration lighting apparatus, comprising a plurality of ring-shaped bodies, positioned about a central axis (A) and provided with respective plurality of lighting sources, in particular LEDs, and connected to one another by means of joints comprising pins so as to be differently oriented with respect to one another; the plurality of ring-shaped bodies being connected to one another by means of the pins made of electric conductive material and which contact pairs of electric terminals arranged on adjacent ring-shaped bodies, so that the adjacent ring-shaped bodies are rotational with respect to one another by means of the pins and are electrically connected by means of the same pins; the apparatus being characterized in that pairs of adjacent ring-shaped bodies are connected by at least one pin which supports the two ring-shaped bodies and contacts respective electric conductor blocks arranged on both said adjacent ring-shaped bodies and which include the terminals; and in that on each ring-shaped body each block contacts the pin and connects the pin to an electric circuit which supplies the sources arranged on the same ring-shaped body.
