For example, it is typical to see germicidal lamps used in commercial water purification applications operating continuously, with annual lamp replacement to ensure reliable disinfection performance. However, when looking at the lamp specifications, this lifetime is only achievable with a limited on/off cycle rate. So it is understandable why engineers would ask or expect that UV-C LEDs achieve similar or longer lifetimes. Low-pressure germicidal lamps traditionally used in these markets are typically associated with lifetime claims of 8000 to 10,000 hours. Rethink lifetime relative to operating hours These potential regulatory barriers, consumer preference for nontoxic products, and the competitive pressure from startups provide strong motivation for established water purifier OEMs to consider UV-C LEDs.
Some have speculated that in the future, manufacturing companies may be financially responsible for the disposal costs of mercury used in their products. However, in August 2017, the Minimata Convention on mercury entered into force with the stated goal of phasing out mercury in everyday products. Startups, driven by a need for innovation and differentiation and without the legacy bias toward germicidal lamps, tend to move directly to evaluate and adopt UV-C LEDs.įor decades, established water purifier OEMs have relied on low-pressure germicidal lamps to provide proven UV disinfection. Both startups and established brands are looking to capitalize on this trend.

In Asian point-of-use (POU) water markets, a real and genuine concern for the microbial quality of tap water is spurring explosive growth for countertop and portable consumer and commercial water purification products. It is a variable factor that engineers can control after considering how the UV-C LED will be used.
LED lifetime is not a fixed specification. It’s typically prompted by current design experience with traditional UV-C sources, like low-pressure germicidal lamps, or perceptions of visible LED products. Without question, “What is your product lifetime?” is a common inquiry heard by UV-C LED manufacturers from engineers considering an LED-based UV-C source for disinfection. UV-C LEDs such as the device pictured above can be designed into compact water purification systems like the one shown here, enabling safe water at the point of use (POU).
