How to design a dimming fluorescent electronic ballast
Dimming fluorescent lamps is an attractive feature that provides mood and brightness effects as well as having tremendous energy savings potential. Designing a dimmable electronic ballast, however, is a complicated and challenging task. This paper presents an overview for designing a dimming electronic ballast for a T5 35W lamp. Lamp requirements, dimming control methods, and resonant output st...
متن کاملDigitally Addressable DALI Dimming Ballast
A digitally addressable digital dimming ballast has been developed. It conforms to DALI standard requiring very few parts and operates at very low power. Applications include building management or studio lighting where it is desired to control single or groups of lamps for conserving energy, performing lamp maintenance or creating prefect light quality. The design includes the digital dimming ...

متن کاملMethod of controlling external electrode fluorescent lamps for local dimming of liquid crystal displays
This paper proposes a method of controlling external electrode lamps (EEFLs) for local dimming of liquid crystal displays (LCDs). In the proposed method, each EEFL is divided into four partitions using external electrodes formed on the outer surface of the lamp. The luminance is controlled by varying the duration of ac power applied to the center electrode of each partition. The shape of the ex...
متن کاملSingle Stage Ballast for Hps Lamps
In this paper will be reported the study and implementation of a single stage High Power Factor (HPF) electronic ballast for High Pressure Sodium (HPS) lamps using a LCC filter. In the recent years many authors are working to obtain single stage HPF electronic ballast for fluorescent lamps [1][2]. Normally to obtain HPF in electronic ballast for high pressure sodium lamps a Power Factor Preregu...
