PROBLEM TO BE SOLVED: To provide an LED light, where a light unit can be rotated arbitrarily, the angle of projection light can be adjusted, and the direction of projection light can be adjusted while holding energization of the input route of a power supply. SOLUTION: The LED light mainly includes a light stand, and the light unit installed on the light stand. The light stand enters a bored hole installed on a metal piece playing a role of the input end of a power supply fixed to the end of the light unit by two conductive metal cylinders for providing erection operation to and combining the light unit. When the light unit is rotated around the two metal cylinders as axes, the metal cylinder of the light stand and the metal piece of the light unit hold electrical connection, thus allowing the LED of the light unit to maintain an emitted state.
