A series of mini-lights help to decorate parties, special events and holidays. Trying to understand their twisted 3-wire, 120-V alternating current (VAC) composition can be difficult without prior knowledge. In fact, it's pretty simple. Here's how to have designed and put together.
mini-light strings made today .
A few lengths of light mini-series (from 15-to-150-feet) are available to consumers today, each holding a different number of clear or colored mini-bulbs. However, recent attempts to standardize the production of light wire is focused on making 50-bulb sets that can be used only as a series, or can be pre-assembled in several 100-150 bulb wires. Each completed a series regardless of its length has electricity at each end of the strip. This standardization seems to be true of the older pipes in the form of an incandescent lamp (with its fibers enclosed within a 3-mm diameter lamp), a newer type of LED (s light emitting diodes crept the bulbs ).
Currently newer LED arrays are more expensive than incandescent, but they use less electricity than the filament type. However, the production of light short sequences of any species with fewer than 50 bulbs and still do, and they can be found in stores. However, they are not a large part of the current mass production of mini-lights.
So, every full length of any number of bulbs will have a male plug at one end, a female connector at the other end. Also, these caps are made so that individual wires can be stacked (two or three of them connected to piggyback on each other at each end to a total string longer) without causing electrical connection neuspjeh.Muški each set also has two small 3-amp fuse in a kiss him, one for each of its two main 120-volt wire. However, these fuses will blow if the complex sequences are too long or if too much power drawn by them.
To illustrate the description of the 3-wire a series of mini-lights, this article uses a 100-bulb string, which contains two 50-bulb sets pre-manufactured as a single string. Each bulb in these two sets is rated at about 2.5 volts. Tj = 120-volts/50-bulbs 2.4-volts/bulb
Mini-light-string design and installation of .
Basically, the two wires in any three-wire mini light string carries a 120-volt household electricity from one end of the string to the other end in a similar way to any extension cord does. The so-called third wire of the string contains all the mini-bulbs and sockets in the sequence of a few centimeters apart. This so-called third wire holding the bulb is in turn connected to each of the two 120-volt wire in parallel.
That is, one end of the lamp cord is connected to the first of two 120-volt wire to one end of the whole niza.Drugi end is connected to another 120-volt wire to the other end of the paper remains the same series. For a 100-bulb string, a second set of 50-bulbs connected to two 120-volt wire in the same way on the string from the first set, which operates independently of the first seta.Završio range can be from 20-to-50-feet long, depending on the spacing between bulbs.
These links are hard to see just by looking at the finished product, because all three wires twisted around each other to keep them firmly in the rope as a string, leaving only the bulbs exposed. However, each of these two sets of the parallel 120-voltage, because they draw their energy from these two wires, which allows them to operate independently of each other.
Another advantage of this parallel connection of the electricity itself continues to flow through the main two wires from one end to connect the other end of the connector, if one or both sets of bulbs is not any reason. As a result, when a 100-bulb light string starts running light bulb, the bulbs may not appear in either one or both sets. For example, a 50-bulb set may have all or some of its lights are not working, while another set could show all of your lamp is lit in a row for each set of operating separately from the other one. Since the current is still flowing in the second example (a few lights still work), some of the bulbs in the absence of expensive to replace.
