Electrical modeling of the power delivery to an LED array packaged in a textile

Recent technologies enable large arrays of LEDs to be integrated into textiles, which has applications in the lighting industry. Two analytical modeling techniques are proposed that calculate the supply power at a source necessary to provide the LED drivers with a minimum voltage. The modeling techniques show a correlation with numerical simulations to within 10% but can be implemented for very large LED arrays where, for time constraints, numerical simulations become impractical. The modeling allows a designer to optimize the location of the supply voltage, which can reduce the increase in voltage over the ideal voltage by 40%.
