Abstract
A LED driving device is provided. The LED driving device includes a multi-segment linear LED driver, first current-compensating device and second current-compensating device. The LED driving device is used to drive a LED device which is composed by a plurality of serial LED modules. The multi-segment linear LED driver selectively provides a first path to a first LED module of the LED modules for flowing a first constant current, or provides a second path to the first LED module and a second LED module of the LED modules for flowing a second constant current. When the first path is provided, first compensating current flows through the first current-compensating device. When the second path is provided, the first current-compensating device stops conducting the first compensating current. When the second path is provided, second compensating current flows through the second current-compensating device.
