SETi latest product UVTOP LED life more than 10000 hours

Is located in Columbia city of South Carolina led Sensor ELectronic Technology Inc manufacturer (SETi) continuous improvement of production technology, has recently demonstrated its deep ultraviolet (UV) LED UVTOP275, life more than 10000 hours. Methods to predict the LED life is measured according to the principle of statistics several batches of overload experiments in TO-39 metallic glass measuring device having a window in the LED package to be measured, the average output power of 0.8mW, the emission wavelength is 280nm + 5nm.

Life analysis is based on the standard SETi procedure performed at room temperature (about 23 DEG C), driven by DC 20mA, LED no heat sink or not do heat treatment test, about 2000 hours, the output power is reduced to the initial power of 50% (L50). According to the test results, UVTOP275 life of more than 10000 hours, far more than other traditional UV light source.

SETi production of LED light wave range of 240nm~360nm, its products have passed ISO9001 quality system certification, is the band below 365nm's leading international LED manufacturers. Although SETi does not release the longest life expectancy of its products in the UVTOP product specifications, but UVTOP275 is expected to live under the conditions of L50 will be close to 5000 hours, and SETi is still developing a longer life test LED products.
