The present invention relates to a current balance circuit for efficiently driving an LED light and lamp. The current balance circuit of the present invention comprises: a current driving source for supplying a current; a plurality of LEDs arranged in parallel; and one or more mutual inductance coils which receive current from the current driving source, and supply the same current to the plurality of LEDs by the mutual inductance of a primary coil and a secondary coil which have the same number of turns. Alternatively, the current balance circuit of the present invention comprises: a current driving source for supplying a current; a plurality of LEDs arranged in parallel; and one or more mutual inductance coils which receive current via the LEDs and render the current flowing through the LEDs the same by the mutual inductance of a primary coil and a secondary coil which have the same number of turns. Whereby, the present invention controls the current applied to each of the LEDs to be the same during the serial or parallel driving of the LEDs when manufacturing a light or a lamp using LED elements, thus producing LEDs with improved reliability, long lifespan, and maximized efficiency, and reducing manufacturing costs for an LED driving circuit. |
