LED floor lamps with dimmable features have transformed spaces, bringing in a dash of contemporary styling. In combination with other lighting, they help to improve the décor of living spaces. Dimmable LED floor lamps greatly help to tone down the intensity of the light. LEDs are some of the most energy efficient lighting units. Here is a closer look at the workings of a dimmable LED floor lamp.
Pulse width modulation dimming method
It is important to understand that despite the appearance of dim light, LEDs do not actually emit dimmer light. LEDs function in two modes – ON and OFF. So effectively, what is observed as dim light is actually light being emitted in pulses at alternating intervals. This pulsing of the light is controlled by the dimmer, which determines the intervals and the intensity of the pulsing.
Frequency of pulses designed to create the effect of continuous light to the naked eye
Pulsing light, should ideally appear as pulses of light broken up with intervals of darkness in between; more like a flickering lamp or wick. However, a flickering light is definitely not the ideal light for floor lamps. A floor lamp requires continuous light, therefore, PWM LEDs are designed to emit light in pulses at a high rate, which will create the effect of continuous light.
