Light source incorporating a high temperature ceramic composite and gas phase for selective emission |
摘要 |
A light source includes a base, a light-transmissive envelope coupled to the base, a composition disposed within the light-transmissive envelope, and a gas phase contained by the envelope for suppressing vaporization of the composition at operating temperatures greater than about 2000 Kelvin. The composition includes a first region and a second region and operable to suppress or reflect photons having a wavelength greater than about 700 nm and to emit or transmit photons having a wavelength between about 400 nm and about 700 nm.
