LED Lamps with AC Dimmer: TRIAC or MOSFET — Compatibility Guide 26.02.2026 0 19 Short answer: There are two types of AC dimmers: TRIAC (leading edge — for incandescent bulbs, halogen, heaters) and MOSFET AC dimmer (trailing edge — purpose-built for LED lamps). If an LED lamp flic... Arduino LED MOSFET TRIAC ac-dimmer trailing-edge tutorial Mehr lesen
Trailing Edge vs Leading Edge: Which Dimmer Method to Choose 26.02.2026 0 19 Short answer: Leading edge is the standard TRIAC dimmer — it opens the load in the second half of each AC half-cycle (best for incandescent bulbs and heaters). Trailing edge is a MOSFET dimmer — it op... Arduino LED MOSFET TRIAC ac-dimmer leading-edge trailing-edge tutorial Mehr lesen
LED Flickering with AC Dimmer: TRIAC or MOSFET — Causes and Fixes 26.02.2026 0 21 Short answer: LED flickering with an AC dimmer has three distinct root causes. Types 1 and 2 are caused by TRIAC architectural incompatibility with LED lamps — the hardware fix is a MOSFET AC dimmer (... Arduino ESP32 LED MOSFET TRIAC ac-dimmer flicker tutorial Mehr lesen
