RIPPLE ELIMINATION DEVICE FOR SUPPLY

摘要

Disclosed is a device for eliminating a ripple in power supplied to a light emitting diode. For an example, in a ripple eliminating device for a light emitting diode, the ripple eliminating device for a light emitting diode includes an IC device which has one end connected to the cathode of the light emitting diode; a capacitor filter which is connected between a ground and the other end of the IC device and eliminates a ripple element in a current element flowing in the light emitting diode; and a switching device which is connected to the cathode of the light emitting diode and has a control electrode connected to the IC device.
