Abstract
Abstract
The influence of the temperature of two white LEDs, a good brand and one of unknown brand, on their characteristic curves and their light properties was experimentally evaluated in the range from 10 °C to 95 °C. The measurements show that the luminous efficacy decreases with increasing temperature, specially of the LED of unknown brand. In addition, a small redshift could be observed of the blue peak of their respective spectra, as well as changes in their correlated color temperatures (CCT).
