LED LIGHTING DEVICE AND ILLUMINATION APPARATUS INCLUDING SAME |
摘要 |
An LED lighting device includes two or more switching circuits connected between a power source and an LED (light emitting diode) unit, an inrush current limiting circuit which limits an inrush current flowing through the LED lighting device when power is turned on and a trigger circuit which generates a trigger signal of an operation/non-operation of the inrush current limiting circuit from the switching circuits. Further, the inrush current limiting circuit is set in a non-operation state when any one of the switching circuits is started first. |
