Claim Text:
1. A flexible illumination-module circuit board comprising: a heat sink; an insulating support layer on the heat sink and formed with an opening exposing the heat sink; and a metal-film on the insulating support layer, which is subdivided into different sections with different functions; a plurality of separate metal-film sections directly on the insulating support layer and flanking the opening in the insulating support layer, which are used as an electrical conductor; a light-emitting diode at the opening and connected electrically to at least one of the sections; and a thermal connection extending through the opening and engaging the heat sink and the light-emitting diode to dissipate heat from the diode to the heat sink and a section of metal-film separate from the sections flanking the opening and lying wholly between the diode and the thermal connection, which is used to transfer the heat from the diode to the heat sink, wherein the insulating support layer is composed of polyimide, polyvinyl butyral (PVB), polyvinylfluoride, ethylene vinyl acetate (EVA) or a similar plastic material, and the metal film is composed of copper, aluminum, silver, tin, a tin alloy, or a tin-plated copper foil.
