| 摘要 |
The present invention relates to a light emitting diode (LED) lighting device which converts AC power into DC power to use the same, removes an afterimage generated after blocking an AC power switch, and includes a plurality of LEDs. According to the present invention, at least ten LEDs are connected in series to form a serial LED array, and the LEDs included in the serial LED array are unitarily or multiply grouped to connect an after-image removal resistor in parallel to the LED of each group, thereby removing, by using a resistor string, floating charge remaining in both ends of the LEDs as resistance heat when the LEDs are turned off. |
