- W2103136342 abstract "The lifetimes of two white high-power LEDs were studied based temperature-acceleration life test. the acceleration temperatures were selected as 100°C and 90°C separately in the experiment, and the accelerated time was 800 hours. Based on Arrhenius model, activation energy of the two tested samples are 0.6978 and 0.7014 separately, and lifetime are7.41×10 5 h and 1.46×10 5 h separately. Our experimental results showed that the quality of the two type LEDs is very different, and lifetime of 50000 hours is recommended as the threshold of entering the market for high power white LEDs." @default.
