|Technology evolution in Luminescence and
Luminescent technology is essential
technology in human life and its effect on national energy
policies is significant. In this regards, major advanced countries
are regarding the technology as core technology for reduction
of energy consumption and improvement of global environment
and those are investing huge resources on it.
Most advanced countries are restricting the specification
of lamps which consume 20% of total electricity generated
and promoting the use of high-efficiency luminescent lamps.
Also in environmental viewpoint, EU is restricting the use
of 6 harmful components like Mercury, Lead and Chrome in the
lamps. In this regards, it is very important issue to develop
new luminescent technology and commercial lamps which meet
both demands of high-efficiency and environmental-safety.
Currently, the most widely-used lamp is fluorescent lamp
(FL) or cold cathode fluorescent lamp (CCFL). But they are
containing mercury vapor in them and should be substituted
due to the environmental restrictions. However, there¡¯s lack
of good alternatives for them.
Recent research and development in this field are focusing
on producing highly efficient and environmentally safe luminescent
lamp which is much closer to solar light. Mercury contained
in the lamp should be minimized (current FL contains about
25 mg per lamp). This kind of research deals with LED, PDP
and EL, but the performance is not as good as current FL,
in the comprehensive viewpoint of efficiency, life time, brightness,
electricity usage and price. However, one of the most promising
alternatives is ¡®Field emission (FE) lamp¡¯, which shows lower
usage of energy, high efficiency, fast response and no use
of gas like mercury. It¡¯s based on cold-cathode under vacuum
VALLOY is a member of international collaborative research
for new luminescent source of Field Emission Lamp, which can
be widely applicable in various fields.
Products and Technologies of VALLOY
VALLOY will commercialize UV lamp, which is the first application
of FE lamp technology.
There¡¯s no UV lamp which can show higher efficiency and better
performance than FE lamp.
VALLOY is looking at environmental market first, for example,
Sick Building Syndrome, which is internationally hot issue
because it is directly effecting on everybody in the office
VALLOY¡¯s FE UV technology can cure the problem remarkably.
VALLOY is also preparing commercialization of EcoGreen food
garbage box, which can eliminate smells and bad pollutants
by preventing rotting of foods. The product is also using
UV light and ozone generation.
VALLOY will introduce the new remarkable printing media,
which is lightening for itself without help of backlight units
like FL or CCFL. The basic technology is based on EL but very
different from other EL applications. This Self-Lightening
Flex can be used for outdoor signs, indoor posters, attachment
on the glass, car wrapping, advertising on the round surface
like column and other applications. The product is as bright
as current sign panels and consumes less than 30% of energy
required by current FL based sign panels
