The LED lamp system includes straight-tube type LED lamps each having LED elements and a dedicated power source for lighting the LED elements. The dedicated power source full-wave rectifies and smoothes a commercial AC power source, outputs constant current having a ripple factor of 1.3 or smaller and thus lights the LED elements.
