  • Publication number: 20130194814
    Abstract: A bent layered structure is disclosed having a top conductive layer and a dielectric layer. The dielectric layer is a polyimide derived from at least 70 mole percent aromatic dianhydride based upon total dianhydride content of the polyimide and at least 70 mole percent aromatic diamine based upon total diamine content of the polyimide. The bent layered structure has a radius of at least 2 mm and a bend angle of at least 45 degrees at least once along a longitudinal or at least once parallel to the longitudinal axis or both and maintains a 150 to 350 V/micron breakdown voltage.

  • Publication number: 20130193452
    Abstract: A light emitting diode system is disclosed having a bent layered structure conformed to a least a portion of a self-supporting three dimensional heat sink and maintains a breakdown voltage from 150 to 350 V/micron. The bent layered structure has an electrical circuit, a dielectric layer and at least one LED package, LED chip on board or mixtures thereof attached to the electrical circuit. The dielectric layer is a polyimide derived from at least 70 mole percent aromatic dianhydride based upon total dianhydride content of the polyimide and at least 70 mole percent aromatic diamine based upon total diamine content of the polyimide.
