摘要

In recent years, conventional mercury lamps used for ultraviolet(UV)curing and other purposes are being replaced by UV-LEDs, which provide several important benefits such as longer lifetime, lower energy consumption, and no hazardous waste. However, difficulties of irradiance measurement of UVLED and calibration problems of UV-irradiance meters have also arisen. This study compared commercial UV-irradiance meters of seven types to investigate irradiance measurements of UV-LEDs. As reference values for comparison, irradiance values of three types of standard LEDs for UV-LED were used, and they were calibrated against the spectral responsivity standard. Comparison results demonstrated that most of the reading of UV-irradiance meters differed from our UV-LED calibration values by about 10-30 . These differences were resulted from disagreement of spectra between the reference source used in each UV-irradiance meter calibration and the UV-LED. It was improved by spectrum mismatch correction.
