Patent ID: 10830416

Abstract:
A light guide component and a light source device. The light guide component comprises a reflecting plate (131) having an aperture and a transflective coated plate (132). The reflecting plate (131) reflect light. The aperture allows light to pass through. The transflective coated plate (132) is connected to the reflecting plate (131) and covers the aperture, and transmits an excitation light and reflects light of a color different from that of the excitation light. The light source device comprises: an excitation light source (110), for generating excitation light; the light guide component, for transmitting, through the aperture and the transflective coated plate (132), the excitation light generated by the excitation light source (110); a color light generation device, for receiving the excitation light passing through the transflective excitation (132), and generating converted light by using the excitation light; and a light collecting component, for collecting the converted light generated by the color light generation device. The light guide component can reduce waste of converted light.
