Optimal Design of High Power LED Driving Circuit

Abstract:

The loss of high power LED is analyzed and calculated. It is pointed out that high power LED driving circuit is required to be designed in detail instead of using BCD to 7-segment decoder. An example with 5 inch LED is presented. Some decoder circuits are designed and compared showing that the MC1413 is the optimal one. Example circuits are designed. The experiment results are in positive to the analysis results showing the feasibility of the proposed methods.
