A light source unit includes an LED mount bar and a set of LEDs. The LED mount bar has an inside channel that is located at a center portion of the LED mount bar, and outside channels that are located at outside portions of the LED mount bar, respectively. The set of LEDs is disposed in the inside channel and the outside channels. The set of LEDs is ranked into a plurality of chromaticity regions within a predetermined chromaticity range in a chromaticity coordinate system and ranked into a plurality of luminous flux ranges according to a luminous flux value of the LEDs, respectively. The inside channel including a plurality of first LEDs from a subset of the set of LEDs. The subset of LEDs is ranked in a predetermined chromaticity region of the chromaticity regions and ranked in a predetermined luminous flux range of the luminous flux ranges. |
