Method to design alternating current light-emitting diodes luminous flux

Fluctuation of current through alternating current operated light-emitting diodes (AC LEDs) make luminous flux simply equivalent to the product of power consumption and luminous efficiency unreasonable, unlike constant current scenario. Based on application model and average luminous efficiency introduced by this paper, relationship between AC LEDs luminous flux and its application circuit parameters, including balance resistor, threshold voltage and equivalent resistor of LED etc. was presented. Then method to design AC LEDs through single LED photoelectric characters to meet luminous flux requirement was given.
