Ultraviolet Light Emitting Diodes / Ultraviolet LED have numerous applications
across various industry fields. Applications include displays, lightings / Ultraviolet lamp,
spectro-fluorometry, photo-catalytic reactions, high-resolution optics,
anti counterfeit, biological detection, medical applications, UV air purifier,
along with countless other UV activation related applications.
Ultraviolet LED can offer sharper peak profiles, lower power consumption, longer life,
and more compact profiles compared to conventional ultraviolet lamp.
Space propagation based optical transmission is suitable for short-range communications
because they do not rely on cables or electrical waves. However, due to interference
from sunlight and rays from light producing equipment, they can only be used
in special environments. Because the intensity of sunlight and fluorescent lamps
becomes abruptly weaker at wavelengths shorter than 380nm, light sources with
wavelengths less than 380nm enable effective signal transmission in the dark.
UV ray has been widely used for erasing EPROMs (Electrically Programmable Read Only Memory),
i.e. by exposing the EPROM under UV ray for a few seconds. During semiconductor manufacturing,
specifically the lithography stage, UV ray is used to expose the photoresist
and define mask patterns on the wafer. An anti counterfeit detector generates UV ray, which will be reflected
by counterfeit bills, and hence activating the alarm. UV ray can also be used
in the detection of chemical substances and the analysis of human genomes.
Recently, UV ray have been found effective in cancer treatment, and various
research programs have been underway. Applications to build environmental equipment
through the use of UV ray, in conjunction with photo-catalytic reactions
to decompose toxic substances into non-harmful components, are attracting attention within
the industry as well.
Large-scale ultraviolet lamp units currently available in the marketplace have
limited applications due to their size. If a 0.3mm UV emitting device is manufactured,
numerous other applications can be developed. UV detectors without sensitivity
to sunlight have been developed at many research centers, however, ultraviolet LED as
a source has not been widely recognized.
We have recognized this need in the marketplace and would like to offer our
products in an attempt to help develop these applications that can benefit from
ultraviolet LED technology. Below, we provide some technical data of our ultraviolet LED applications
on ultraviolet lamp.
