Design and implementation of high-power- factor dimmable fluorescent lamp ballast circuit

Abstract

Lighting is an essential element of home and work environment that affects lives of people in many different ways. In Sri Lanka, people spend significant amount of their electric hills on lighting. As one of the widely used lighting solutions hath in industrial and household applications, improving the quality and reliability of fluorescent lamps are certainly of great importance Enabling of dimming with the improvement of the power factor not only makes the fluorescein lamps more economical and reliable, it also adds the benefit of more user satisfaction over existing designs The proposed implementation of the design is commercially viable since it has man) commercial benefits over similar products available in the marker Although die initial installation costs of the product is quite high compared to conventional ballast, the payback time is considerably less especially when die product is used with multiple lamps at the same time
