Light system using flexible printed circuit boards

A light system, comprising:

• at least three separate individual rigid metal LED heat sinks each having a respective substantially planar outwardly facing LED support surface;
• a flexible printed circuit board comprising:
• a flexible substrate;
• a plurality of LEDs carried by the substrate;
• a plurality of electrical control components carried by the substrate and adapted for selectively controlling illumination of the LEDs;
• a plurality of electrical input components carried by the substrate and connectible in electrical communication with an electrical source to supply electrical power to the flexible printed circuit board;
• and
• a plurality of electrical traces carried by the substrate and in electrical communication with the LEDs, the electrical control components and the electrical input components;
• wherein the electrical traces are configured to cooperate with the electrical control components and the electrical input components to form a circuit configured to carry current from the electrical source through the LEDs and back to the electrical source under control of the electrical control components and the electrical input components;
• wherein LED regions of the flexible printed circuit board carrying the LEDs are disposed on the outwardly facing LED support surfaces of the LED heat sinks whereby the LED heat sinks can dissipate heat from the LEDs and wherein light-emitting surfaces of the LEDs are outwardly facing;
• wherein adjacent ones of the LED heat sinks are foldably coupled to one another by joints formed by fold regions of the flexible printed circuit board extending between respective spaced-apart edges of the adjacent ones of the LED heat sinks;
• wherein the LED heat sinks are arranged relative to one another so that each adjacent pair of the outwardly facing LED support surfaces are non-parallel to one another whereby the outwardly facing LED support surfaces are disposed on notional faces of a notional polyhedron.
