PROBLEM TO BE SOLVED: To provide a light measuring device for light source to which a light guide device is connected, wherein the light measuring device is applicable more widely, and sure determinations on whether actually emitted light output is sufficient are made. SOLUTION: The present invention relates to the light measuring device 34 for light source, to which the light guide device 24 is connected. The light guide device 24 is provided with a light-emitting surface 30 on the light output side, and the light measuring device 34 is provided with a stop for bonding an optical sensor arrangement 36 to the light guide device 24. The optical sensor arrangement 36 includes at least two optical sensors 40a, 40b, 40c, ..., 40o capable of irradiating light from the light-radiating surface 30. COPYRIGHT: (C)2008,JPO&INPIT
