  • Patent number: 9055645
    Abstract: A light emitting unit includes a plurality of light emitting devices. A control apparatus includes a rectifier for converting an alternating current (AC) signal into a ripple signal by rectifying the AC signal. A ripple signal adjuster reduces a level difference between maximum and minimum levels of the ripple signal, and outputs the resultant ripple signal as a drive signal. A turning-on controller controls turning-on of the light emitting devices in accordance with a level variation of the drive signal.
