We are offering brand new UV LED by unique concept of AlGaN technology, which realize shorter wavelength than existing UV LED can reach, with higher energy efficiency that conventional mercury lamp can not achieve.We hope the great advantage of our UV LED expand the possibilities for the applications of UV curing, analysis, sensing and UV sterilization.
Available wavelength of DOWA UV LED and the existing UV LED
The remarkable complement has been attained; extremely shorter wavelength with high light output power.
The range of wavelength of our UV LED Conventional light source(mercury lamp) vs UV LED
We will create new value by enhancing the innate advantages of LED(low heat generation, high electric efficiency, long life and non-toxicity) in wide range of deep UV wavelength.
The examples of application of DOWA UV LED
UV curing
A photo polymerization initiator which is firstly radicalized by the power of UV light source and accelerates curing of oligomers continuously.
With our UV LED...
DOWA UV LED (shorter than 350nm) is expected to perform better in curing application, which is not well by existing 365nm UV LED.
Sensing
UV light reflected by or penetrating object can be used for detecting or position sensing purposes.
With our UV LED...
Short wavelength of DOWA UV LED enable to sense the materials which have been undetected.
UV sterilization
UV light discourage the reproduction of nucleic acid (DNA or RNA), and bacteria will be extinct.
With our UV LED...
For this purpose, 262nm would be the most effective wavelength, however conventional mercury lamp can not provide. DOWA UV LED will be available with this wavelength soon.
