Seoul Semiconductor, a leading LED maker of Korean, has signed an agreement to license its UV patent for a portable fluorescent forgery detector.
Portable fluorescent forgery detectors are mainly applied in identification of forgeries of bank notes, securities, passports, gift coupons, and ID cards by commercial banks, financial companies and small businesses that mainly transact securities. As counterfeit money raise concerns around the world, demand of the product is expected to grow substantially.
Ultraviolet (UV) mercury lamps have been generally utilized in forgery detection, but UV LEDs provide longer lifetime and better performance in durability, output power and eco-friendliness, says Seoul Semiconductor. With increasing restrictions on environmentally hazardous materials, UV lamps are being rapidly replaced by UV LED products in the market, says the company. Additionally, UV LEDs can easily identify forgery even in bright places, comparing with existing UV mercury lamps which can only detect forgery in dark conditions
The patented UV LED technology being licensed was jointly developed by Korea Minting & Security Printing Corp (KOMSCO) and Seoul Semiconductor subsidiary Seoul Optodevice Co Ltd.
