<p>PURPOSE: An LED(Light Emitting Diode) device is provided to prevent malfunction and damage to the LED by converting AC power from a magnetic or electronic stabilizer to DC power. CONSTITUTION: First and second power input terminals(311,313) are respectively inserted into first and second connection terminals of a magnetic or electronic fluorescent lamp. First and second power supply units(331,333) remove an overcurrent or overvoltage included in the AC power from the first and second power input terminals. A rectifier(335) full-wave rectifies the AC voltage outputted from the first and second power supply units. A filter(339) converts the AC voltage from the rectifier to the DC voltage. A driver(341) turns on a plurality of LEDs.</p> |
