SETi achieves over 10,000 hours lifetime on UVTOP LEDs

Under its continuous improvement program, Deep ultraviolet (UV) LED maker Sensor Electronic Technology Inc (SETi) of Columbia, SC, USA has demonstrated lifetime of over 10,000 hours on its UVTOP275 LEDs. The demonstration was performed on a statistically valid group of LEDs from several batches that are representative of UVTOP275 products; the LEDs were packaged in TO-39 metal-glass packages with flat windows and emit at a wavelength of 280nm ±5nm at an average output power of 0.8mW after burn-in.

Lifetime analysis was performed to SETi standard procedure; driven with a current of 20mA DC at room temperature (about 23ºC ambient) with no heatsink or thermal management. The LEDs were physically life tested to about 2000 hours and L50 levels (50% of the LED’s original power) modeled from these tests. SETi says that the demonstration represents a massive leap in operational performance for the firm and far exceeds lifetime for other conventional UV light sources.

SETi manufactures LEDs from 240nm through 360nm to ISO9001 certification and claims to be currently the leading commercial manufacturer of UV LEDs shorter than 365nm. While this lifetime has not been released in the UVTOP product specifications, SETi expects its UVTOP275 LEDs to exhibit L50 lifetimes approaching 5000 hours and is developing future products to meet extended lifetime specs.
