Electronic ballast:
An
electronic lamp
ballast uses solid state electronic
circuitry to provide the proper starting and operating
electrical condition to power one or more fluorescent
lamps and more recently HID lamps.
Electronic ballast
usually change the frequency of the power from the
standard mains (e.g., 60 Hz in U.S.) frequency to 20,000
Hz or higher, substantially eliminating the stroboscopic
effect of flicker (100 or 120 Hz, twice the line
frequency) associated with
fluorescent lighting.
In addition, because more gas remains ionized in the arc
stream, the
lamps
actually operate at about 9% higher efficacy above
approximately 10 kHz.
Lamp efficacy
increases sharply at about 10 kHz and continues to
improve until approximately 20 kHz.Because of the higher
efficiency of the
ballast
itself and the improvement of
lamp efficacy by
operating at a higher frequency
electronic ballast
offer higher system efficacy. In addition, the higher
operating frequency means that it is often practical to
use a
capacitor
as the current-limiting reactance rather than the
inductor required at line frequencies.
Capacitors tend
to be much lower in loss than inductors, allowing them
to more closely approach an "ideal reactance".
Electronic ballast
are often based on the SMPS topology, first rectifying
the input power and then chopping it at a high
frequency. Advanced
electronic ballast
may allow dimming via pulse-width modulation and remote
control and monitoring via networks such as LonWorks,
DALI, DMX-512, DSI or simple analog control using a
0-10V DC brightness control signal. |
