Finally, Germicidal UV LEDs for the Rest of Us!

I was recently asked if I knew where one could get Germicidal UVC LEDs since I had blogged about the technology a while back. Well, I do so I am blogging it here for all to see in case you may be interested. Now I am talking “commercially available” not some pie-in-the-sky R&D type of availability.

Sensor Electronic Technology (S.E.T.) is commercially shipping deep UV LEDs that they call UVTOP LEDs that range in output wavelength from 247 to 365 nm. The output power is typically 0.5 mW at 20 mA forward current. They are typically multi-die, single can LEDs mounted in TO-39 or TO-18 cans. The cans in this case are specially designed with internal reflectors to maximize output. The LEDs are available with or without ball or flat lenses to boost output power and narrow the beam profile.

Being as S.E.T. is the basically the only game in town right now (they have partnered with Seoul Semiconductor so I imagine we will start to see these coming out through Seoul’s distribution channels, especially in Asia and perhaps even see the die technology licensed off) you don’t really have a choice of deep UV LEDs so you’ll have to pay the gigantic price of nearly $300.00 each in single quantities for 250 nm LEDs (they get cheaper the further up toward the UVA you go).

Beyond price, this is still very good news for both S.E.T. and the rest of us in the LED industry since up until now, there wasn’t an alternative so kudos to S.E.T. for the way cool technology and making it available to the rest of us!
