Claim Text:
1. A light source apparatus comprising: at least one LED string including at least one LED and at least one inductance unit disposed in the LED string and configured for generating an induced current according to a change in a current applied to the LED; a main switch configured for controlling power applied to the LED string according to an on/off switching operation; a capacitor charged with a voltage of the power applied to the LED string when the main switch is switched on and configured for applying the charged voltage to the LED string when the main switch is switched off; and a second switch configured for controlling the power applied to the LED string from the main switch according to an on/off switching operation, wherein the capacitor is charged with the voltage of the power applied to the LED string when the main switch and the second switch are switched on, and applies the charged voltage to the LED string when the main switch or the second switch is switched off.
