Wide range of uses for UV LEDs


Wide range of uses for UV LEDs

Page view

The spectrum of ultraviolet light contains all wavelengths from 100 nm to 400 nm and is generally subdivided into three categories: UV-A (315-400 nm, also known as long-wave UV) and UV-B (280-315 nm, also known as medium wave). UV), UV-C (100-280 nm, also known as short-wave UV).

Dental treatment instruments and identification applications are early applications of UV LEDs, but performance, cost and durability benefits, as well as extended product life, are rapidly increasing the use of UV LEDs. Current uses for UV LEDs include: optical sensors and instruments (230-400 nm), UV identification, barcode (230-280 nm), surface water sterilization (240-280 nm), identification and body fluid detection and analysis (250-405 nm), Protein analysis and drug discovery (270-300nm), medical phototherapy (300-320nm), polymer and ink printing (300-365nm), identification (375-395nm), surface sterilization / cosmetic sterilization (390-410nm ).

Environmental impact - lower energy consumption, reduced waste and non-hazardous materials UV LEDs have significant environmental benefits compared to alternative technologies. Compared to fluorescent (CCFL) lamps, UV LEDs consume 70% less energy. In addition, UV LEDs are ROHS certified and do not contain mercury, a hazardous substance commonly found in CCFL technology.

Ultraviolet LEDs are smaller and more durable than CCFLs. Since the ultraviolet LED has anti-vibration and impact resistance, it is rarely damaged, thereby reducing waste and cost.
