Neon Sign Tube Light Circuit

A worker skilled in this craft is known as a glass bender neon bender or tube bender.

Neon sign tube light circuit.

One characteristic of these elements is that each atom has a filled electron shell so the atoms don t react with other atoms and it takes a lot of energy. A neon transformer is rated for its secondary open circuit voltage and secondary short circuit current. 99 get it as soon as fri oct 2. You can make a fake neon sign yourself but real neon lights consist of a glass tube filled with a small amount low pressure of neon gas.

Open circuit voltage ocv appears at the transformer s output terminals only when no neon tubing is connected to those terminals. Open circuit voltage no current flowing is typically 7500 to 15000 volts between the 2 secondary legs. The important part is selecting the correct transformer the size and capacity of which is based on the voltage requirements of the neon sign. A neon lamp is simply a small glass tube filled with a low pressure gas such as neon.

With basic skills and tools you can diagnose and repair your neon sign. Neon tubes are at about 1 15 atmospheric pressure whereas fluorescent bulbs are only at about 1 750 atmospheric pressure. Sometimes with additional small amounts of krypton argon etc. The installation and wiring process for a neon sign is standard and will work regardless of brand or type neon sign.

This page was created to help you the do it yourselfer fix repair and or replace parts on your neon beer or other neon signs. Neon is used because it is one of the noble gases. The ne 2 will fire at around 90 volts ac or dc then the operating voltage will drop to about 60 volts. I took the circuit board and transformer off the neon and attached it to a florescent bulb and that light just stayed on didn t blink.

To change the color from the normal orange. When operating a neon tube the rms lamp voltage is roughly half the open circuit voltage and the lamp current is roughly 80 of short circuit current. Likewise short circuit current is only drawn from the output terminals if a short is placed. If you don t use the right transformer your neon sign could fail to operate properly.

Some things can be fixed other things like broken or burned out neon tubes or weak or burned up transformers must be replaced. The neon tube is made out of 4 or 5 foot long straight sticks of hollow glass sold by sign suppliers to neon shops worldwide where they are manually assembled into individual custom designed and fabricated lamps. Neon tube signs are produced by the craft of bending glass tubing into shapes. Require ballast circuitry like fluorescent most neon bulbs need a high voltage so they need a ballast circuit.
