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.
New look – Dimmable LED floor lamp
A perfect dimmable LED floor lamp offers a warm amber glow to transform the ambience of your room. The dimmable feature enables light to be adjusted to emit at levels ranging from bright task lighting to dim, soft, cosy tones. The exciting designs of dimmable floor lamps help to improve the aesthetics of interiors. The sleek and compact designs help to create wonderful lighting from stunning light accessories.
Working principle incorporates the Analog technique
Analog dimming technique is the underlying principle used to dim LED floor lamps. The forward current supplied to the LED bulb is controlled, and the linear power supply to the bulb causes the dimming effect. Due to the changes in temperature, the light emitted from low quality dimmable LED bulbs may lack the intensity, therefore it is important to choose dimmable LED bulbs of high quality.
Challenges for dimmable LEDs to flourish
Demands exist for LED manufacturers to develop dimmable LED bulbs. However, it needs to be borne in mind that users generally like to retain their fitments, and it becomes necessary for manufacturers to develop LED bulbs that can be retro fitted. Though the technology is relatively new, it has time and again been demonstrated to work with utmost efficiency. The demand for dimmable LED bulbs is increasing and the day is not far off when LED bulbs will reign over the lighting world with their designs, features, durability and savings in cost.
The digital age has also rendered in exciting possibilities for network controlled lighting and wireless controls. The main dimming methods are TRIAC dimming, PWM dimming, and linear dimming. It is time to illuminate in style and take the style to levels that exist in the most creative minds.
