| Abstract: | Based on the characteristic of constant-current driving, the authors discussed the control method for the high power LED, designed and actualized a project which has comprehensive function. The new project can not only actualize the dimming function of high power LED and carry through the real-time short circuit and fault detection, but also can shut off automatically when short circuit occurs, so it is an ideal solution for the control of high power LED. |
