How does the LED dimming work?

If you’re spending a romantic night in, watching a movie, or even playing your favorite video game, dimmable LED lights are ideal for generating mood lighting. This short tutorial will arm you with valuable morsels of information that will enable you to buy with total confidence before you rush out to buy a new set of dimmable LED Lights.

First and foremost, LEDs are not dimmed due to voltage changes (as is the case with their incandescent counterparts.) Because light is emitted from a semiconductor chip, it is either on or off, and the LED will operate at the same voltage and current as if it were producing full light output.
The LED, on the other hand, generates a “dimming effect.” Pulse-width-modulation (PWM LED) and analog dimming are two methods for accomplishing this (sans cool-sounding acronym.)

What Are Dimmable LED Lights and How Do They Work?

Pulse Width Modulation (PWM) and analog are the two basic ways for dimming LEDs. Dimmable LEDs work by generating a dimming effect in the case of PWM. Unlike traditional illumination such as incandescent bulbs, Dimmable LED Lights do not rely on voltage to control their brightness. Instead, they rely on a cycle of being turned on and off. Because these cycles take milliseconds to complete, you won’t notice them turning on and off. For instance, if you dim your lights to 10%, they will be ‘on’ for 10% of the time and ‘off’ for 90% of the time. The procedure for analog is fairly straightforward. The current is adjusted here to dim or brighten the lights by increasing or decreasing the voltage.

What Causes Flickering in Dimmable LED Lights?

The dimmer switch is frequently the primary source of flickering with dimmable LED lights. Dimmer switches have a minimum load that they can handle (in short, the amount of Watts it can process). Because popular leading-edge dimmer switches are primarily built for older bulbs with larger wattages in trailing edge dimming, their minimum load is high. Because LED Lights use so little energy, you may not be able to power enough of them to meet the minimum need. You can use dimmable led power supply for them. That’s why, to avoid any potential flickering, you’ll need an appropriate LED dimmer switch. The quality of the dimmer switch you use will have an impact on how well your lights work. A high-quality dimmer switch will include a variety of dimming modes and ranges. Most of the time, flickering dimmable LEDs may be fixed by simply adjusting the dimmer’s mode or resetting the dimmer to factory settings.

Why are dimmable LEDs taking so long to catch on?

The issue for LED makers is to create a low-cost LED that can be retrofitted into existing installations and can function with several existing dimming-control methods and new wireless network-control scenarios. This is a tall order. While dimmable LEDs are now on the market, the technology is still in its early stages. Prices will certainly become more consumer-friendly as time goes on, at which point we will likely see wider adoption of LED technology in more and more households.
