Abstract
A light emitting diode (LED) lighting apparatus boosts alternating current (AC) power output from a ballast, rectifies the boosted AC power to direct current (DC) power, blocks generation of an inrush current while the boosted AC power is rectified, and controls an operation of an LED by using the DC power.
Claims10
A light emitting diode (LED) lighting apparatus for driving an LED by supplying alternating current (AC) power through a ballast, the LED lighting apparatus comprising:
- a boosting unit for boosting and outputting the AC power output from the ballast;
- a rectifier for rectifying the boosted AC power to direct current (DC) power;
- an inrush current breaker for blocking generation of an inrush current while the rectifier rectifies the boosted AC power;
- and
- an LED driver for controlling operations of the LED by using the DC power supplied while the inrush current is being blocked.
A light emitting diode (LED) lighting apparatus for driving an LED by using supplied alternating current (AC) power, the LED lighting apparatus comprising:
- a ballast for outputting the supplied AC power to AC power of a predetermined voltage to stabilize driving of the LED lighting apparatus;
- a boosting unit for boosting and outputting the AC power output from the ballast;
- a rectifier for rectifying the boosted AC power to direct current (DC) power;
- and
- an LED driver for controlling an operation of the LED by using the rectified DC power.
