PROBLEM TO BE SOLVED: To provide a light emitting diode which can be lighted by regardless of AC or DC. SOLUTION: The diode is basically constituted by using four diode elements and one light emitting diode element. It can deal with a wide range of voltage by using a constant current diode element, and a lighting starting voltage can be decided by using the constant current diode element.
