Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an improved collimator for guiding light from a light source.SOLUTION: In the flat reflective collimator assembly having a light source such as a light guide body and an LED, a side surface of the light guide body forms a collimating reflective surface having a paraboloid shape with a collimating focus arranged on an axis of the light guide body. The center of the light guide body forms a main reflective surface having a virtual focus which is substantially the same as a collimating focus. The collimating focus is formed as the paraboloid shape, or a plurality of paraboloid portions having various focus distances and common collimating focuses. Moreover, the collimating reflective surface may have a dispersive optical system.
