What is tint control?
The typical way to dim an LED is by reducing current flow. However, as the current is reduced, the tint of the LED can shift toward the green part of the spectrum. The other common way to reduce brightness is to turn the LED on and off very rapidly – often referred to as PWM (Pulse Width Modulation) or PFM (Pulse Frequency Modulation). However, PWM can generate an annoying flickering sort of like a disco strobe and results in a lower overall system efficiency. We use a more sophisticated algorithm for dimming the LED that minimizes both the amount of tint shift and the annoying flickering while increasing the total system efficiency.
