ABSTRACT:
An island submount used for carrying at least one light-emitting element having at least one electrical contact. The island submount includes a substrate, at least one island structure having a top surface and an inclined surface, and a conductive layer. The island structure is located on the substrate and corresponds to the electrical contact. The conductive layer is formed on the surface of the island structure and at least covers the top surface, so as to be electrically connected with the electrical contact. The island submount is capable of enhancing the light extraction efficiency of the light-emitting element, and avoids the energy loss due to re-absorption when the light emerging from below the light-emitting element is reflected back to the light-emitting element.
