PROBLEM TO BE SOLVED: To provide a light-emitting diode light source with required optical output characteristics. SOLUTION: The LED light source is provided with at least one LED for a first color, at least one LED for a second color, and at least one LED for a third color, as well as a plurality of current controllers each connected to at least one LED for the first color, at least one LED for the second color, and at least one LED for a third color and controlling brightness levels of the respective colors. At least one LED for the first color, at least one LED for the second color, and at least one LED for the third color, as well as the plurality of current controllers are mounted on the same circuit board, and the light source is provided with a memory stored in the circuit board. The memory stores values for controlling an amplitude of each output current of the plurality of controllers, and a combined optical output of the light source is to be set by a value stored in the memory.
