Deep UV LEDs Have Highest Output Power

Dowa Electronics Materials has successfully developed a deep ultraviolet LED chip, which it says feature the world’s highest output power of 90mW, with a peak wavelength of 310 nm, and dimensions of 1 mm × 1 mm. Deep ultraviolet lights with a wavelength of 310 nm are used for curing and skin therapy. Replacing conventional mercury and excimer lamps with these LEDs enables equipment to be smaller and mercury-free. With the advantages of long life time and power saving, this product is expected to find new applications.
