FLUORESCENT LIGHTING: Overview
The fluorescent bulb offers a very efficient source of
light. The efficacy of a light source is a measure of the light output
vs. the power input. The typical efficacy range of a fluorescent bulb
is 80 – 120 lm/W, which is ten times higher than the typical
incandescent bulb.
A fluorescent
bulb cannot be directly connected to a source of power. Fluorescent
bulbs have a negative impedance characteristic when the bulb is lit.
The bulb resistance will decrease as bulb current increases, resulting
in a runaway effect.
A ballast circuit is required to
control the amount of current in the bulb. The ballast circuit could
be as simple as a resistor, but this solution would not be very
efficient. An electronic ballast provides the best
efficiency
