In this paper, a multi-lamp T5 digital dimming electronic ballast is developed to improve the electronic ballast in the lamp failure which is unable to clearly determine whether the lamp is good or not and the disadvantage of non-filament preheating start. It can effectively extend the lamp life of the fluorescent and has the function to protect the lamp tube from being broken down. Finally, a multi-lamp T5 digital dimming electronic ballast is designed and implemented for four 14W T5 fluorescent lamps to verify its performance. The experiment results show that this multi-lamp T5 digital dimming electronic ballast successfully lit these four T5 fluorescent lamps and has functions of filament preheating, lamp tube protection, and digital dimming control.
