The present invention relates to a super-high efficiency LED lamp driving apparatus. According to the present invention, the super-high efficiency LED lamp driving apparatus includes: a rectification unit (10); a plurality of LED lamps (LED1,...,LED13); a plurality of operation switches (LS1,...,LS12) operating such that the LED lamps (LED1,...,LED13) which reach a drive critical voltage are turned on in serial order; a plurality of shift switches (SW1,...,SW12) connected to a tap between the LED lamps (LED1,...,LED13); and an LED shift control unit (30) operating a shift switch such that the lighting of the LED lamp is shifted to a termination in the case of the existence of the turned-off LED lamp. |
