摘要：The present invention relates to a device for driving LEDs and, more specifically,to an AC-direct drive-type LED driving device, capable of sequentially driving LEDsconnected in series in reverse order by starting with an LED located at the end until a
certain size of power is supplied, and sequentially driving the LEDs connected in series inorder if the certain size of power is supplied, rather than measuring the size of a rectifiedpower and sequentially driving the LEDs connected in series based on the measured sizeof the power; thereby equalizing the power consumption of all the LEDs connected inseries to thereby equalize the life span of the LEDs regardless of the serial connectionorder of the LEDs and unifying the brightness of all the LEDs connected in series.
