The present invention refers to super diode structure LED driving current mirror type using relates to device. The present invention according to current mirror type LED driving device a current source, said current source (LED string) string LED plurality of which are connected in parallel and a light-emitting part and said LED tires and flatly constructed products consisting said current won which is disposed between each said plurality of LED string the same structure built with contacts a plurality of current mirror current mirror circuit and many controlling codes are set up, said current mirror unit tires and flatly constructed products LED said circuits are each said current won said transistor and disposed between the base terminal terminal and collector of transistor between the system power source and the buffer amplifier and feedback diodes characterized in that including circuit part. According to the present invention, additional headroom voltage (headroom voltage) without using an accuracy (accuracy) performance (uniformity) and a uniformity a are evaluated as typical for balancing a current (current balancing capability) to improve the power supplies the light to the liquid..
