Does LEDs color temperature change during the exploitation?

LEDs light color changes during the operation because it depends on such factors as:

  • 1. diode operating temperature
  • 2. power supply method — charging with direct current or pulse power
  • 3. luminofor degradation — in case of white color with luminofor LED, the color depends on the characteristics of luminofor

Pace of aging depends on the quality of LED module and the correctness of its application in the particular solution (correctness of power supply, cooling correctness).
