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....
Electrodeless lamps have long bulb life, but their application areas are limited in situations where replacement costs are high. In such areas, a communication way is required between ballasts and a control system as well. This paper presents a serial communication module realization method using an erasable programmable logic device. To verify the proposed method, a 150 W prototype ballast was made...
