Tasavirtavälkkyminen
Tasavirtavälkkyminen, also known as constant current flashing or PWM dimming, is a technique used to control the brightness of light-emitting diodes (LEDs). Instead of directly reducing the voltage supplied to the LED, which can alter its color temperature and efficiency, tasavirtavälkkyminen rapidly switches the LED on and off at a high frequency. The perceived brightness is determined by the ratio of the "on" time to the "off" time, known as the duty cycle.
This method is preferred in many applications because it maintains a constant current flowing through the
Tasavirtavälkkyminen is commonly implemented using pulse-width modulation (PWM) controllers. These circuits generate the on-off pulses with
The advantages of tasavirtavälkkyminen include precise brightness control, maintenance of LED color and efficiency, and suitability
