PROBLEM TO BE SOLVED: To provide an LED lighting device that can suppress the generation of bright and dark streaks even if imaged with a digital camera mounted with a CMOS image sensor.SOLUTION: The LED lighting device includes: an alternating current power supply (AC power supply 100); a rectification circuit (AC/DC converter 101) for rectifying an alternating current of the alternating current power supply; a control circuit 103 for controllingly outputting a direct current rectified by the rectification circuit as two or more systems of pulse signals P1, P2 out of phase; and two or more systems of LED arrays 20a, 20b driven by the two or more systems of pulse signals output by the control of the control circuit with a time difference depending on the phase shift. |
