A light conversion device and high-intensity, solid-state light source utilize wavelength conversion elements with a thermal conductivity greater than 1 watt per meter per degree Kelvin (W/m-K). Exemplary materials that have high thermal conductivity include monocrystalline solids, polycrystalline solids, substantially densified ceramic solids, amorphous solids or composite solids. The light conversion device and high-intensity, solid-state light source have at least one heat sink that is in direct thermal contact with the wavelength conversion element. The heat sink quickly dissipates heat generated within the wavelength conversion element in order to prevent the wavelength conversion element from overheating and undergoing thermal quenching of the wavelength conversion and light emission.
