    Why has the colour appearance of the LEDs changed after some period of use?


    There are several possible reasons why this happens as follows:

     

    • The LEDs are being overrun by the use of inappropriate driver.
    • The application temperature is different from the operating temperature noted in the LED datasheet.
    • There may be heat build-up due to improper thermal management.
    • The phosphor may have degraded due to overheating or other reasons.
