►Quick Detail:
Excellence Kehua KHB420 12V 20W ZY800 ZY1200 fully automatic
biochemical analyzer light source bulb
The light source bulb is the light source bulb of a fully automatic
biochemical analyzer. The general process of light transmission is
as follows: the composite light emitted by the bulb (12V, 20W
placed inside the heat sink) is focused together by a condenser
lens (maximizing the use of light source energy), the incident
light is converted into parallel light by a collimator lens, and
then enters the grating through a slit (to avoid stray light
entering). The grating decomposes the composite light into multiple
monochromatic lights, reflects them onto a filter (absorbs each
monochromatic light), and then sends them to a detector (a column
of light-emitting diodes) for photoelectric conversion. Finally,
the signal is transmitted to the display screen through a signal
processing board for analysis, calculation, amplification, etc.

► How to determine the malfunction of a light bulb:
If the fully automatic biochemical analyzer around you shows an
alarm message of "abnormal light bulb energy", you can immediately
think that the light bulb may be old and needs to be replaced.
However, considering that the fully automatic biochemical analyzer
is a relatively large and precise instrument.
You need to find a light bulb of the same model as the automatic
biochemical analyzer you have on hand for purchase and replacement.
Before replacing the light bulb, you need to click on "Maintenance"
->"Replace Light Bulb" to enter the maintenance interface, which
displays values for 16 wavelengths. From here, you can see the
deviation of the values after replacing the light bulb. Generally,
the new device value should be above 1.0, and the old device value
can also be above 0.7. After replacing the light bulb using this
method, it was found that the values of wavelengths 340 and 578
were incorrect. Wavelength 340 corresponds to a value of 0.36,
while wavelength 578 corresponds to a value of 0.5, both of which
are lower than the standard value of 0.7 mentioned above. Clicking
on the alarm option above still shows an "abnormal energy of the
light bulb" alarm. After replacing the light bulb, click on the
light bulb maintenance interface to check if the device prompts
normal operation. If all displays are normal, it indicates that the
bulb replacement is reasonable.
