Moving Flame LED Candle Construction & Inner Workings
The picture below illustrates the
construction of a typical moving flame LED candle. A tealight is being used in this illustration
instead of a larger pillar candle because it’s easier to see how the components
fit together and interact with each other in the smaller tealight. The basic construction is the same between
pillars, tealights, votives, tapers, etc.
A small, thin support wire is used to hold
the moving flame element in place and provides a pivot axis for it to move
around from side-to-side. The LED is
aimed upwards towards the moving flame element and illuminates it as it moves
around on the support wire.
A permanent magnet is mounted to the bottom
of the moving flame element. This
permanent magnet interacts with the magnetic field produced by the
electromagnet located on the circuit board.
This interaction is the mechanism behind the movement of the moving
flame element. Notice that the
electromagnet is made of a coil of small gauge wire. Short pulses of current, of varying strength
and of varying occurrence in time, flow through this coil of wire which are
generated by electronic circuitry on the circuit board. These short and varying pulses of current
generate a resulting magnetic field which interacts with the magnetic field
produced by the permanent magnet located at the end of the moving flame
element. To illustrate this principle,
imagine taking the north poles (or south poles) of a couple of magnets and try
touching the poles together (all magnets have 2 poles – a north pole and a south
pole). It’s very difficult because a
rather strong force is keeping the poles from touching each other. They are opposing each other since the poles
have the same polarity. This is the same
principle which causes the moving flame element to move from side-to-side. The electronic circuitry creates a short pulse
of current to flow in the electromagnet.
The current is such that it generates a magnetic field with one pole
above the electromagnet and the opposite pole on the backside of the electromagnet. The electronic circuitry is designed to
produce a magnetic pole above the electromagnet that is the same polarity as
the magnetic pole at the bottom side of the permanent magnet located at the
bottom of the moving flame element. Since
the pulse of current is short, the magnetic field (and resulting poles) are also
short, so the moving flame element is momentarily deflected. Not only are these magnetic fields (and
resulting poles) very short in duration, but the strength and time between
pulses are both variable. If these
pulses are orchestrated properly, the result is a random, life-like movement of
the moving flame element! The strength and timing of the short electromagnet current pulses is what differentiates the moving flame action for the various brand names of moving flame LED candles.
One last component that
needs to be mentioned is the battery. Different types and sizes of batteries
are used in moving flame LED candles depending on the type and size of the
candle. The battery in the picture below is a rechargeable Lithium-Ion battery
that's found in our rechargeable tealights, and the smallest of our tealights
will typically use a small CR2450 Lithium button cell battery. The larger
pillar candles will typically use larger batteries such as C and D-cell
batteries; however, some brand names will use AA batteries. Pillars and votives
typically use AA. If you are ever in doubt as to which battery a candle uses,
carefully check the description and specification's table because we always
specify which batteries are required. And, don't forget that
LightsandBatteries.com also sells batteries, so we are your one-stop shop for
all of your flameless LED candles and accessories!
Moving Flame LED Candle Brand Names: Luminara, Avalon, Torchier, Liown, Mystique and Everlasting Glow
One of the most frequent questions we get has to do with the
differences between all of the different brand names of moving flame LED
candles and which ones are the best.
carries moving flame LED candles designed and manufactured by several different
companies and are sold under several different brand names.
Just about everyone who is a fan of moving flame LED candles has heard
Luminara Worldwide, LLC is
headquartered in Minnesota and is not only a well recognized brand name, but
they also design their own moving flame LED candles and have them built in Asia
by various manufacturers.
flame LED candles are sold to distributors around the world who in turn sell to
retailers who ultimately sell to the end user (our customers).
The exclusive USA distributor of Luminara
moving flame LED candles is Darice who does not rebrand them and sells them
under the Luminara brand name to retailers around the country.
Another big name in the world of moving flame LED candles manufacturer
of moving flame LED candles is Liown Electronics Co., Ltd. which is headquartered
Liown designs and manufactures
candles that are sold under several different brand names such as “Avalon”, “Mystique”,
“Torchier” and their own brand name which is simply “Liown”.
As with Luminara discussed earlier, moving
flame LED candles designed and manufactured by Liown Electronics are sold to distributors
around the world who in turn sell to retailers who ultimately sells to the end users.
The USA distributors are listed below along
with their associated brand names.
The Light Garden – “Avalon”
GKI/Bethlehem Lights – “Torchier”
The Boston Warehouse – “Mystique”
RAZ Imports – “Liown”
These distributors have partnered with Liown Electronics and are
responsible for various phases of product development such as packaging,
marketing, public relations and product launches. At the time of the writing of this article,
The Boston Warehouse had just acquired GKI/Bethlehem Lights, and it is unsure
if they will operate as a separate business unit while maintaining the Torchier
brand name or if they will be absorbed into The Boston Warehouse and use an existing
brand name (e.g., Mystique). It’s also
possible that a completely new brand name will be developed. Interestingly enough, Liown Electronics used
to have a partnership with Luminara, but that partnership was dissolved back in
August, 2014 for complex reasons. Both
Luminara and Liown have multiple patents on various moving flame and non-moving
flame LED candle technologies.
Another quality moving flame brand name not associated with Luminara or Liown is "Everlasting Glow" which is distributed by The Gerson Companies. The Gerson Companies is headquartered in the USA and has offices in Hong Kong and China where the candles are designed and manufactured.
LightsandBatteries.com also exclusively offers moving flame LED candles
designed and built by several overseas manufacturers and are simply sold under
the brand name of “LightsandBatteries.com”.
All of the moving flame LED candles that LightsandBatteries.com offers
are of similar quality and have a similar moving flame action, so you can
expect a good quality product whether you are purchasing Luminara, Avalon,
Torchier, Mystique or our own LightsandBatteries.com” brand name.
So, which one is the best? Well, we feel they are all the best, or we
wouldn’t carry them!
Also, by carrying several
different brand names, we can provide our customers with more products, more options
and various price ranges.
between brand names might include things like moving flame action, LED color, LED
brightness, wax density, required battery size, battery life, remote control
features and the overall product offering.
The diagram below summarizes everything just discussed and illustrates
where LightsandBatteries.com fits into the grand scheme of things.
LightsandBatteries.com is an online retailer
since we buy in quantity from the various distributors or directly from various
manufacturers, and our job is to provide quality moving flame LED candles to
the end user.
