Description
The SemiLED UV LED uses proprietary MvpLED technology, a patented structure and metal alloy substrate, giving it 40% external quantum efficiency at 350mA. These C3535U-UNx1 UV-A LEDs are capable of operating at high currents (up to 800mA) with high output power density; giving the curing industry a better and more cost-effective solution.
On February 10th 2015 we published a related article on our high-power UV LED: "Ultra-Violet (UV) High Power LED Product and Applications Overview".

LED Star MCPCB
We offer this UV reflowed on your choice of two different metal core printed circuit boards (MCPCB) versions: a single (1-Up: 1 LED) and triple (3-Up: 3 LEDs). The 1- Up is a single UV LED reflow soldered to a 20mm hexagonal (LED Star) MCPCB. The MCPCB has four large solder pads for easy solder connections. The 3-Up is three (3) UV LEDs reflow soldered in-series to a 20mm hexagonal MCPCB. The 3-Up MCPCB has two solder pads for connections, mounting holes for compatible secondary optics and a center hole for wires or securing the LED star to a heat sink.
Wavelengths
The UV LED is available in two different wavelengths: 400nm to 410nm or 410nm to 420nm

Optics Ready™ — Choose Your Beam
The Optics Ready™ platform brings together secondary optics from Fusion Optix, Carclo, Khatod and other leading manufacturers. Optic and holder compatibility varies by LED emitter and board configuration. Choose from the compatible accessories listed for this product, or contact our solutions team to confirm the right optic and beam for your application.
Images, Part Numbers & Notes
Select the LED options near the 'add to cart' button to see the corresponding product image and part number. For referencing detailed specifications there are tables and downloadable documentation below. Important Note: Unless noted otherwise the specifications list are for a single UV LED. This means that in most cases the values need to be tripled for applications with the 3-Up version. For Example, if the forward voltage listed is 2.95V @ 350mA, then the 3-Up version would be 8.85V and the lumen output would be tripled as well.

FAQ
Frequently Asked Questions
Q: Can I look at these UV LEDs?
A: No! UV-A (315nm-400nm) can pass through the cornea to the lens of the eye. Overexposure can lead to cataracts by creating oxidant that cause rapid formation of cataracts. Exposure to the skin causes suntans, but not sunburns. Sunburns are caused by UV-B. Please take protective measures for yourself and others when using UV LEDs!
