Description:
Of ultra high pressure mercury lamp power supply must have high
dynamic characteristics and current limiting measures. Because of
the super high pressure mercury lamp does not belong to the fixed
resistive load, but a negative resistance characteristics of the
load. Since it is the use of mercury vapor conductive
light-emitting devices, and it must be up to several kilovolts
instantaneous high voltage to the trigger ignite, and therefore
require power supply system must have a high voltage trigger link:
at the same time also want to load characteristics, in the moment,
light resistance, two stage almost short circuit state, at this
time, must limit the impact current, or electric current will be
out of control, far higher than that of mercury lamp launch safety
current, will burn mercury lamp even caused an explosion of the
mercury lamp, thereby causing serious consequences.
The constant power mercury lamp power supply is a control mode of
high voltage trigger and large current.Not only the lighting
process is stable, but also the starting current, power stability
and other characteristics.And there is voltage, current display and
so on.
Applications:
Mainly used in scientific and industrial fields, such as light
source curing, lithography machine, etc. Laser simulation and
effect illumination projection in entertainment industry.
Fluorescence microscope, spectrophotometer, endoscope, cold light
source and other optical instruments. Xenon short arc lamp,
microscope; Graphic scanning; Color contrast; Endoscopy. Commercial
film screening; Projection of the slide; Television video
projection; The searchlight. Follow spot; Simulate the sun lamp.
