FE UVR Lamp + Photocatalyst for Environmental Applications
The first promising application of FE lamp in the market.
VALLOY is developing functioned FE UVR (Ultra violet Radiation)
Lamp in combination with photocatalyst for indoor air purification
purpose. This will be the first step application of FE lamp
commercially. Finally, FE lamp can be used for LCD backlight
units and general white light lamps in the future.
Currently UV lamps are used for below applications.
- Sterilization : Anti-rotting, Narrow range purification
of water and air
- Industrial use : Exposure, Drying, Cleaning and etc.
- Others : Deodorization, Anti-insect, Interior fluorescent
lightening and etc.
FE UVR Lamp can be applied to the listed application and
moreover it can be applied to much wider applications by its
differentiated features of high-efficiency, narrow pick of
wavelength, high-intensity, flexible shape and size, environmental
safety, low consumption of energy, long life time and etc.
VALLOY is looking at our first application of FE UVR lamp
in the indoor air cleaning market.
Photocatalyst is commercialized in 1980¡¯s. Theoretically,
it is very useful for environmental purification of air and
water, due to the high energy when UV-activated electron
comes back to the catalyst.
Photocatalyst has typical features as below.
- Oxidation and decomposition of organic compound
- Sterilization (anti-bacteria effect)
- Hydrophilic property
FE UVR LAMP with Photocatalyst for indoor air purification
Photocatalyst need to be activated by UV light of a specific
wavelength. Sun light also contains UV light but there¡¯s too
little amount of UV light indoor through the window glass
activate the photocatalyst. Even the installed UV lamps indoor,
which can be found in the market, are not suitable for activating
photocatalyst because it cannot activate photocatalyst which
is more than 5 cm away.
So, the experiment data in the lab may not be reliable in
real field applications. FE UVR lamp has high intensity to
reach 2m away photocatalyst and very suitable for the indoor
purification application. FE UV lamp can make the current
TiO2 photocatalyst really applicable in actual field.
Activated photocatalyst by FE UV lamp can remove
toxic components and bacteria in the indoor air and help the
building environment maintained clean enough. VOC (Volatile
Organic Compounds) like Formaldehydes, Odor compounds like
Ammonia, molds and bacteria can be perfectly removed on the
surface of photocatalyst and hydroxides generated from the
H2O vapor on the catalyst surface.
In this regards, FE UVR Lamp can be used for various applications
- Resolution of Sick Building Syndrome : the fastest method
to remove VOCs like Formaldehydes
- Air purification / deodorization : in combination with the
photocatalyst-coated wall papers and tiles
- Reduction of Dioxins : the most cost-effective methods for
- Built-in module of electric products like air conditionals,
heaters, air purifiers, refrigerators and etc.
- Built-in module of interiors : clothes chest, footwear chest,
waste box and toilette free from moisture, molds, odors and
- Built-in module of automobile : perfect control of SOx,
COx and NOx in car exhaust gas
Especially VALLOY is looking at ¡°Sick building syndrome¡±
market, recognized as a medical condition in the 1980s, results
in symptoms such as a stuffy nose, itchy eyes and throat and
respiratory problems like asthma. The symptoms are especially
common in people who work in air-conditioned offices, where
heavy growth of bacteria and fungi is common within the ventilation
¡°FE UVR Lamp + Photocatalyst¡± will be the only existing resolution
for this hot environmental issue.
