Synchronous dimming control for a cold- cathode fluorescent lamp driver - Electronics Letters
lation is created of randomly transformed copies of the original DFG. A fitness is allocated to each member of the population. This is determined by calculating the supply voltage and effective capacitance of the DFG. Area requirements are computed for the adders, delays and multipliers. The total required area is used to estimate the effective capacitance. The GA selects a member of the popula...
متن کاملA Dynamic Pspice Model for High-Frequency Fluorescent Lamp with Continuous-Dimming Operation
Fluorescent lamps were first introduced to the world in the 1939 World’s Fair. They are low-pressure mercury discharge lamps. Since then, the fluorescent lamps have been the mainly lighting source due to their merits of high color rendering, soft-visualization, long life, and energy-saving. Unfortunately, however, all gas discharge lamps cannot directly connect to a voltage source and require a...
متن کاملHigh Frequency Resonant Inverter for Group Dimming Control of Fluorescent Lamp Lighting Systems
Fluorescen t power SUPPlY Dimmer I Electronic bal last I Lamp IAn electronic ballast for fluorescent lamp lighting using a new resonant inverter is proposed. The electronic ballast has high efficiency, light wcight and small sizc bccause the resonant inverter operates at high frequencies with low switching losses. The inverter output power can be continuously controlled by regulating the L-C re...
متن کاملFiat Lux: A Fluorescent Lamp Tkansceiver
The prevalence of electric discharge illumination has led us to consider ways to use discharge lamps for communication. This paper describes an optical transceiver system which transmits by modulating the lamp arc. The prototype power electronic lamp ballast uses a pulse frequency modulation scheme which ensures no perceptible flicker.
متن کاملHow 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...
