摘要： A multiple light source unit includes a plurality of light sources for emitting light beams. There is a condensing lens and the light beams are parallel to an optical axis of the condensing lens. Included is a mirror for directing the light beams from the plurality of light sources to the condensing lens. A light guiding element for receiving the condensed light beams through a light receiving section and for emitting the light beams through a light emitting section is also provided. The light beams from the plurality of light sources are incident, through respective positions on the condensing lens, into the light receiving section of the light guiding element.
