摘要 |
An LED driving apparatus converts AC input power into predetermined DC output power and supplies the DC output power to an LED load. The LED driving apparatus includes a switching element Q1 to be turned on and off, a ripple current reducer 3a that is connected in series with the LED load and reduces current ripples of the LED load, and a controller CNT that turns on and off the switching element according to a feedback voltage taken from a connection point of the LED load and ripple current reducer, thereby controlling the DC output power to a predetermined value.
