| Title | Design and Implementation of LED Driver Circuit | ||
| Keyword | |||
| Abstract | Abstract In this thesis, a LED driving circuit with current balance strategy is proposed. A multiple series and parallel LED circuits on a panel is built for performance evaluation. A positive voltage reference is referred to collocate with voltage follower to drive the multiple series and parallel LED circuits. Balance currents for each series LEDs are given even the referred positive voltage is varied in a wide range. In addition, the LEDs current can also be controlled to dim in the range of 0~100%, during which the spectrum image will not be changed and the situation of color shifting will not be appeared. The experimental results demonstrate the feasibility of the proposed circuits and are so close to the predictions. |
