More Information
Summary:An LED illumination system comprises a light control apparatus, and an LED illumination instrument including first and second LEDs. The light control apparatus includes: a first control unit determining a total amount of average currents to be supplied to the first and the second LEDs at every predetermined cycle depending on an operation amount of a first operation unit; a second control unit determining a ratio between the average currents to be supplied to the first and second LEDs respectively at the every predetermined cycle depending on an operation amount of a second operation unit; and a supply unit generating currents having the total amount of the average currents and the ratio between the average currents determined by the first and second control units at the every predetermined cycle by using a DC power source and supplying the currents to the LED illumination instrument.
