| description | The present invention provides an assembly comprising a thermally conductive thermoplastic polymer as a heat sink to provide thermal management for an electrical/electronic component and a reaction injection molded (RIM) polyurethane to replace the potting compound typically used in such assemblies. In addition to replacing the potting compound, the cured polyurethane forms the part, such as the base of the LED bulb, which heretofore has been a separate component, thus reducing the number of components and saving a production step. |
