A dimmable electronic ballast for wired or wireless remote control of electrodeless fluorescent lamp group lighting systems

This paper presents a dimmable electronic ballast for wired or wireless remote control of a group lighting system and its control algorithms. The proposed ballast consists of a resonant inverter, an erasable programmable logic device (EPLD) for dimming, and a MCU for ballast control and communication with the group management server. 150 W ballasts were made and used to confirm their performance. The implemented system was controlled well with the host server through the wired and wireless communication, and a constant power control algorithm for the lamp also worked properly.
