Fiat 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.

Fluorescent Lamp Modelling for Voltage Fluctuations

Measurements of Distributions of Ba Atom Density and Electrode Temperature in Low-pressure Fluorescent Lamp

The lifetime of a fluorescent lamp mainly depends on the loss of Ba atoms from its electrode, i.e. the rate of Ba atoms loss controls the lifetime of the lamp. The mechanism of the loss has not been clarified yet sufficiently. We have investigated relationship between electrode temperature distributions and characteristics of Ba atom emission in a fluorescent lamp which are measured by using bl...

Electrical feedback control for driving mercury-free flat fluorescent lamp

Joung-Hu Park Jong-Bok Baek Bo-Hyung Cho Abstract — Recently, a mercury-free flat fluorescent lamp has been developed for LCD backlight application, utilizing a glow-discharge mode instead of a discharge contraction. This paper proposes a lamp-driving system with a feedback loop which prevents discharge contraction and stabilizes the operation of the lamp ignition and radiation. By measuring th...
