<P>PROBLEM TO BE SOLVED: To restrain variation of an optical output due to an individual difference of solid light emitting elements. <P>SOLUTION: A light emitting device 1 in this embodiment has an information holding part 11 for holding information relating to electric characteristics of light source parts 10A, 10B, and 10C, i.e., information indicating a relationship between a driving current and an optical output of each of the light source parts 10A, 10B, and 10C. Therefore, when the light emitting device 1 is connected to a lighting unit 2, an adjustment part 21 of the lighting unit 2 adjusts a driving current supplied to each of the light source parts 10A... from a power source part 20 based on the information acquired from the information holding part 11, and therefore, variation of an optical output due to an individual difference of light emitting diodes can be restrained. <P>COPYRIGHT: (C)2013,JPO&INPIT |
