Abstract
A light emitting module includes 7 colors (2700K 5700K, violet, blue, cyan, lime, and red) of LEDs. With the light emitting module, by causing each of the 7 colors of LEDs to emit at a predetermined intensity, it is possible to emit high color rendering mixed light that has a correlated color temperature from 5000 to 6500K corresponding to the color temperature of daylight, and that can achieve an average color rendering index Ra and a special color rendering index R9 of 98 or greater (99), and a special color rendering index R12 of 94 or greater.
