Abstract
A driving system used for light emitting diodes relating to a controllable driver which can detect the voltage desire from application and adjust driving voltage (V.sub.app1-V.sub.app2) automatically in order to reach a steady driving current. Additionally, users can adjust the setting of driving current and the output value of DC voltage source for application with different voltage and current requirements through a control interface. The over-temperature and over-current protections (e.g. cutting off driving current or setting the upper limit of driving current) are also included in the system for prevention of possible harms. In the system, a driving system is also disclosed for integration of all the mentioned functions but no need of massive space and can be used in LED lighting system or LED backlight system for constant power emitting.
