Why has the color appearance of the LEDs changed after a period of use?
There are several possible reasons why this happens:
The
LEDs
are being overrun by the use of an 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.
