Abstract
The present invention is a dual-source lighting system, comprising: an illumination system comprising: a semi-elliptical reflector; a cover; a first light wavelength conversion layer and a second light wavelength conversion layer, respectively disposed on a focus and a second focus of the cover; a laser light source, projecting to the first light wavelength conversion layer to generate a first excitation light and forming a plurality of reflected lights which are re-focused on the second light wavelength conversion layer and generating a second excitation light; and an image detection system that reads the image signals and relative position information after illumination.
Claims14
A dual-source lighting system, wherein an illumination system comprising:
- a semi-elliptical reflector having a first opening;
- a cover formed at the first opening and having a first focus and a second focus of the semi-elliptical reflector;
- a first light wavelength conversion layer disposed at the first focus;
- a second light wavelength conversion layer disposed at the second focus;
- and
- at least one first laser light source, their emitted laser light projected onto the first light wavelength conversion layer to produce a first excitation light and multiple reflected lights, the multiple reflected lights reflected by the semi-elliptical reflector will again focus on the second light wavelength conversion layer to excite a second excitation light.
