Mini Lights - Understanding the Structure and Setup of the Three Cord Strings Light Bulbs
Single string lights help to decorate get-together, special events, and Christmas. Trying to
be familiar with their unique 3-wire, 120-volt-alternating-current (VAC) assemblages can be
challenging without having foreknowledge. Actually, it can be fairly easy. Here is how they
are specially designed and assemble.
Mini string string lights produced currently.
Some lengths of mini string lighting (from 15-to-150-
feet) are offered to everyone today, each one holding
a separate number of transparent or colored mini-bulb
s. However, recent attempts to standardize the manu-
facture of these light strings has specialized on making
the 50-bulb sets that can either be used alone as one
string, or can be pre-made further into 100-to-150-
bulb strings. Each completed string whatever its extent
has an electrical plug at each end like an extension power cord. This standardization
sounds to be accurate both for the older 3-millimeter-diameter tube-shaped incandescent
light bulbs (with their filaments covered within the bulbs) and the newer LED types.
At this time, the latest LED strings are more luxurious than the incandescent ones, but they
are more useful than the filament types by using minimal electricity. But, the manufacturing
of the shorter light strings of either kind having even less 50-bulbs is still done, and they can
be acquired in the shopping stores. But, they are not a vital part of the prevailing bulk
production of mini-lights.
That is why, each full-length series of any bulb-number will carry a male socket at one tip
and a female post at the other end. At the same time, these plugs are made so the
individual strings can be stacked (two or three of them plugged piggyback into each other
at each end to have the total string longer without causing electrical failure. The male plug
of every string also has two small 3-amp buss fuses within it, one for any one of its two
main 120-volt electrical wires. Yet these fuses will blow if the stacked strings get too
extended or if so much wattage is drawn by them.
Mini-light-string type and assemblage.
Basically, two of the wires on any three-wire mini-light string takes the household 120-volts
of electricity from one end of the cord to the other end similar to the method any extension
power cord does. The so-called third wire of this string keeps all of the mini-bulbs and their
sockets in succession a few inches apart. This supposed third wire supporting the bulbs is in
turn linked to each of the two120-volt wires in parallel. Which is, one end of this bulb wire
is attached to the first of the two120-volt wires at one end of the whole string. Its other end
is connected to the second 120-volt wire at the other end of the set further down precisely
the same string. For a 100-bulb chain, another set of 50-bulbs is linked to the two 120-volt
wires in the same manner further down the string from the set, where it functions
separately from the first group. The finished string can be from 20-to-50-feet long,
depending on the spacing anywhere between the bulbs.
Another selling point of these parallel connections is the electricity itself continues to move
through the two wires from end socket to end plug, if one or both bulb sets fall short for
any reason. As a result, when a 100-bulb light string begins to show unlit lamps, these failed
bulbs might appear in one or both sets. For instance, one 50-bulb set could have all or
perhaps few of its lights not working, while the second set could possibly show all of its
bulbs lit up okay simply because each set operates independently from the other one. Since
the electricity is still flowing in the latter example (various lights continue to be working),
some of the bulbs in the failing set has to be replaced.
