Dimming Compatibility of 60W Replacement LED Lamps with Legacy Dimming Infrastructure

Popis výsledku v původním jazyce

The paper summarizes basic problems of dimming compatibility of modern LED lamps with the legacy dimming infrastructure. In 2016 the legacy incandescent bulbs are going to be forbidden on the European market and thus it must be replaced by modern and energy efficient solid state lighting. The problems with dimming compatibility appeared. Standards phase-cutting dimmers are widely used in the households and consumers expect the modern lighting to have the same properties as the incandescent bulbs. The legacy dimmers are designed for some minimal load (usually 40 - 60 W) while the modern LED lamps replacements have only about 12 W keeping the 60 W incandescent bulb luminous flux (800 lm). Several different problems must be solved in order to keep the dimming ability, avoid the light flickering and keep the dimmer in the safe operation region. There are two basic dimmer types. The leading edge dimmers that are usually based on triac switch and trailing edge dimmers that use MOSFET switche
