Illumination apparatus

摘要

An illumination apparatus including an exciting light source, a reflective switching element, a first wavelength conversion element, and a second wavelength conversion element is provided. The exciting light source emits an exciting beam, and the reflective switching element is disposed on a transmission path of the exciting beam. When the reflective switching element is switched to a first state, the reflective switching element reflects the exciting beam to the first wavelength conversion element so as to excite the first wavelength conversion element to emit a first conversion beam. When the reflective switching element is switched to a second state, the reflective switching element reflects the exciting beam to the second wavelength conversion element so as to excite the second wavelength conversion element to emit a second conversion beam.

主权项

1. An illumination apparatus, comprising:
an exciting light source emitting an exciting beam; a reflective switching element disposed on a transmission path of the exciting beam; a first wavelength conversion element; a second wavelength conversion element, wherein the reflective switching element sequentially reflects the exciting beam to the first wavelength conversion element and the second wavelength conversion element, wherein the reflective switching element reflects the exciting beam to the first wavelength conversion element to excite the first wavelength conversion element to emit a first conversion beam when the reflective switching element is switched to a first state, and the reflective switching element reflects the exciting beam to the second wavelength conversion element to excite the second wavelength conversion element to emit a second conversion beam when the reflective switching element is switched to a second state; and a reflective cover reflecting at least one of the first conversion beam and the second conversion beam.
