PROBLEM TO BE SOLVED: To provide a clock using a light-emitting diode for time indication. SOLUTION: The light-emitting diode clock is provided with a dial face where digits from 1 to 12 are arranged in circle, 12 light-emitting diodes 1 for hour indication 60 light-emitting diodes 2 for indicating minute inside the circle of the light-emitting diodes 1 for hour indication, 60 light-emitting diodes 3 arrange in circle for second indication inside the light-emitting diodes 2 for minute indication, a digital clock body for counting time, a light-emitting diode drive circuit for changing the time signal generated by a digital clock body to a turn-on signal of the light-emitting diodes and driving the light-emitting diodes to indicate present time.
