Solid-State Lighting Device Package

摘要

The present invention provides a lighting device package, which can provide a means for efficient thermal access to the lighting device package in addition to a desired level of light extraction from the one or more light-emitting elements within the lighting device package. The lighting device package comprises a substrate having a thermally conductive region to which one or more light-emitting elements are thermally connected, wherein the light-emitting elements may be relatively closely packed. An optical system is optically coupled to one or more light emitting elements, and is positioned relative to the substrate such that the optical system substantially encloses the one or more light-emitting elements on the substrate. The optical system is adapted to extract the light from the one or more light-emitting elements.
