Title:
発光ダイオードの駆動装置およびそれを使用する照明設備
Document Type and Number:
Japanese Patent JP3172933
Kind Code:
U
Abstract:
A driving device of light emitting diode (LED) and a lighting apparatus using the same are provided. The diving device is adapted for receiving an AC power adjusted by a dimmer and a transformer unit, and includes a dimming match circuit, a voltage conversion unit, and a driver IC. The dimming match circuit receives the AC power and equalize the energy of a positive and a negative half cycles of the AC power, so as to produce a symmetrical AC power. The voltage conversion unit is coupled to the dimming match circuit, and receives and converts the symmetrical AC power into a stable DC power. The driver IC is coupled to the voltage conversion unit, and receives the stable DC power to drive and adjust the light intensity of an LED unit, and thus flicking of the light source of the LED unit can be avoided during dimming.
