<P>PROBLEM TO BE SOLVED: To provide a surface light emitting device whose chromaticity and luminous flux are not out of specifications while all of a large number of LEDs supplied can be used when the large number of LEDs having variations due to individual differences in a chromaticity range, a luminous flux, or the like are supplied. <P>SOLUTION: A required number of LEDs included in a light source unit are sorted into and allocated to individual channels ch1, ch2, ch3 and ch4 of a bar. LEDs having high chromaticity and luminous flux specifications are allocated to the inside channels ch2 and ch3, and a mixture of LEDs having high chromaticity and luminous flux specifications and LEDs having low chromaticity and luminous flux specifications are allocated to the outside channels ch1 and ch4. <P>COPYRIGHT: (C)2012,JPO&INPIT |
