Abstract
A phosphor device of an illumination system is provided. The illumination system emits a first waveband light and has an optical path. The phosphor device includes a first section and a first phosphor agent. The first phosphor agent is coated on the first section. After the first waveband light is received by the first phosphor agent, the first waveband light is converted into a third waveband light, and the third waveband light is directed to the optical path, so that the third waveband light is separated into at least two color lights along the optical path.
Claims20
A phosphor device of an illumination system, said illumination system emitting a first waveband light and having an optical path, said phosphor device comprising:
- a first section;
- and
- a first phosphor agent coated on said first section, wherein after said first waveband light is received by said first phosphor agent, said first waveband light is converted into a third waveband light, and said third waveband light is directed to said optical path, so that said third waveband light is separated into at least two color lights along said optical path.
An illumination system, comprising:
- a phosphor device comprising a first section and a first phosphor agent coated on said first section;
- and
- a first solid-state light-emitting element for emitting a first waveband light to said phosphor device,
- wherein said first waveband light is converted into a third waveband light by said phosphor device, and said third waveband light is directed to an optical path and separated into at least two color lights along said optical path.
A projection apparatus, comprising:
- an illumination system comprising:
- a phosphor device comprising a first section and a first phosphor agent coated on said first section;
- a first solid-state light-emitting element for emitting a first waveband light to said phosphor device, wherein said first waveband light is converted into a third waveband light by said phosphor device, and said third waveband light is directed to an optical path;
- and
- a second solid-state light-emitting element for emitting a second waveband light to said optical path;
- and
- an image processing device arranged along said optical path for receiving said third waveband light and said second waveband light, wherein said third waveband light is separated into at least two color lights by said image processing device, so that said at least two color lights separated from said third waveband light and said second waveband light are projected as an image in a color separation or time division manner.
