Mantenere il freddo: Il ruolo della gestione del calore nell'ottimizzazione della tecnologia LED

For LED technology, from the LED chip to related products such as LED lamps, modules and fixtures, high operating temperature can result in mechanical failure and significant drop of performance.
How a LED behaves when subjected to higher operating temperatures is directly related to its quality. High quality LEDs (such as Nichia or Cree) will function within parameters at high temperatures too, while low quality LEDs will break down, change their color, loose brightness or a combination of these.
- complete failure of the LED
- light output is decreased permanently (Lumen Degradation) even if the issue with high temperature is solved
- light output is decreased temporally while the LED functions at high temperature
- the color temperature of the white LED changes
