Lighting Devices Having Remote Lumiphors that are Excited by Lumiphor-Converted Semiconductor Excitation Sources |
摘要 |
Lighting devices include a semiconductor light emitting device and first and second spaced-apart lumiphors. The first lumiphor has a first surface that is positioned to receive radiation emitted by the semiconductor light emitting device and a second surface opposite the first surface. The second lumiphor has a first surface that is positioned to receive radiation emitted by the semiconductor light emitting device and radiation emitted by the luminescent materials in the first lumiphor. The first lumiphor is a leaky lumiphor in that the luminescent materials therein wavelength convert less than 90% of the radiation from the semiconductor light emitting device light that is incident on the first lumiphor.
