1. A light emitting diode (LED) package structure comprising:

  • at least one LED die;

    a submount having electrodes, wherein the at least one LED die is mounted on the submount;

    a molded package body formed of an electrically insulating material;

    a metal slug extending through the body and molded into the body, a top and bottom surface of the slug being exposed through the body, the submount being mounted on the top surface of the slug such that the at least one LED die is electrically insulated from the slug and thermally coupled to the slug;

    solderless metal connector terminals molded into the body, the connector terminals being electrically coupled to the submount electrodes for supplying power to the at least one LED die, the connector terminals being configured for connection to a power supply without use of solder;

    clamping screw openings formed by the package structure configured to allow the body and slug to be firmly clamped to a thermally conductive mounting structure by clamping screws such that there is a thermal coupling between the bottom surface of the slug and the mounting structure, the clamping screw openings being at least along two opposite edges of the molded plastic body with the slug between the clamping screw openings; and

    metal tabs on a metal plate extending into the clamping screw openings such that a downward movement of the clamping screws presses down on the tabs to increase thermal contact between the exposed slug and the mounting structure.
