Document Type and Number:
WIPO Patent Application WO/2014/121707
Kind Code:
A1
Abstract:
A light source system using a laser to excite fluorescent powder comprises: a first excitation light source (310, 410, 610), a first mirror (330, 430, 530, 630), a collection lens (350, 450, 550, 650), a collimating lens (340, 440, 540, 640), a fluorescent powder layer (360, 460, 560, 660), and a second mirror (370, 470, 570, 670). The fluorescent powder layer (360, 460, 560, 660) is coated on the second mirror (370, 470, 570, 670), the collimating lens (340, 440, 540, 640) has a first surface facing the fluorescent powder layer (360, 460, 560, 660), the first mirror (330, 430, 530, 630) is located on the first surface, and the first excitation light source (310, 410, 610) and the fluorescent powder layer (360, 460, 560, 660) are located at the same side of the collimating lens (340, 440, 540, 640). This light source system is of a small size, has a compact structure, and is designed to easily dissipate the heat.
