Sensor Feedback May Be the Answer to LED Degradation and Color Shift Over Time
LEDs gradually fade in intensity, and they also shift in color over time. How quickly their brightness declines and their color shifts depends on the LEDs and their operating environment. The fabrication of LEDs gives them inherently different brightnesses even when attempting to give them the same brightness. In fact, all …
