Title:
LED DRIVING DEVICE AND LED DRIVING METHOD
Document Type and Number:
WIPO Patent Application WO/2016/064050
Kind Code:
A1
Abstract:
The present invention relates to a light-emitting diode (LED) driving device and an LED driving method for driving an LED while charging a charge element connected to an LED output side when an input voltage is high, driving the LED by a voltage charged in the charge element together with the input voltage when the input voltage is insufficient, and driving the LED with only the input voltage when an LED driving voltage is lower than the input voltage and higher than the difference between the input voltage and the voltage charged in the charge element (that is, when the input voltage can drive the LED).
