MONOLITHIC ILLUMINATION DEVICE

摘要

A monolithic light engine includes a heat sink, a semiconductor light source (e.g., a light emitting diode, a plurality of semiconductor light sources), and a light conduit. The semiconductor light source includes a light-emitting top surface and a back surface thermally coupled to the heat sink. In some embodiments, the monolithic light engine includes a wavelength converter. The wavelength converter converts a first wavelength or range of wavelengths emitted from the light-emitting surface to a second wavelength or range of wavelength light. The light of the second wavelength range enters the light conduit and is transmitted along the length of the light conduit to illuminate an object placed at some distance away from the light source. The heat sink, light source, and the light conduit are mechanically, rigidly coupled (e.g., via one or more mechanical connectors) so as to form a monolithic light engine.
