High colour temperature 3 band phosphor fluorescent lamp

Comparing colour discrimination and proofreading performance under compact fluorescent and halogen lamp lighting.

UNLABELLED Legislation in many countries has banned inefficient household lighting. Consequently, classic incandescent lamps have to be replaced by more efficient alternatives such as halogen and compact fluorescent lamps (CFL). Alternatives differ in their spectral power distributions, implying colour-rendering differences. Participants performed a colour discrimination task - the Farnsworth-M...

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

Simultaneous measurement of velocity and temperature field of high temperature jet using thermographic phosphor particles

In order to overcome existing complicated and costly simultaneous measurement system, an inexpensive and simple measurement system was suggested to measure the temperature field and velocity field at high temperature. The manganese-activated magnesium fluorogermanate (Mg4FGe6:Mn, MFG) which is one of thermographic phosphor with luminescence characteristic of excitation at 385 nm wavelength and ...

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...
