When it comes to neon signs, I believe that the first thing that comes to mind for many friends is the night Shanghai and night Hong Kong, which have been very prosperous in the last century. So far, the neon signs that can be seen everywhere outline the lights of the bustling city, and the colorful light and shadow have shaped the myth of never sleeping. Each neon sign is like a work of art, full of the commercial culture of the times, but also filled with a unique and rich humanistic atmosphere.

With the development of the times, people have more choices in the form of advertising signs. Indoor, outdoor, catering, clothing, different luminous signboard processes to meet the needs of different industries and scenes. But if you want to say that the style is the strongest and the most colorful, it is neon signs, so more and more stores choose to use neon lights as door signs.

Neon lights are actually neon lamps, mainly used as artistic and decorative light sources, and the neon tubes in the neon cannon type high-voltage and low-voltage voltage testers used daily are made of simple neon tubes.

The principle of neon

Neon lights mainly use glass tubes with a diameter of 11~20 mm and a length of 3~6 meters as the lamp, and an electrode is installed at each end of the lamp, and after the glass tube is pumped into a vacuum, it is then filled with neon or xenon, helium, cymnium and other inert gases as the luminescent medium. The light emitted by neon signs is mostly reddish-orange. If the tube is filled with neon, helium, krypton, argon, xenon and other gases, or the glass tube is coated with various transparent pigments, the neon sign will emit a variety of bright brilliance.

The current of neon signs

The voltage used by neon signs is: 6000~15000 volts, its voltage is proportional to the length and diameter of the lamp, but the current consumption is very small, generally 18~30 mA, so neon is a high-voltage, weak current electric light source, should be powered by a holding transformer. At the same time, its power factor is very low (between 0.2~0.47), and it must be equipped with corresponding capacitors to compensate.

Why do store merchants love neon signs?

One of the reasons is that it can be beautiful on its own without relying on other backgrounds to set off the atmosphere, no matter what scene or environment it is placed in, it can be perfectly applied, and it is a "sensible" item that does not need to be thought about with any effort, which is equivalent to a store bonus artifact that is not easy to step on thunder and saves time and worry.

And then it's because the merchants do get the sweetness through it. Customers may not immediately notice the exquisite decoration details at the first glance, but they will definitely be amazed by the dazzling and colorful neon lights! I can't help but think to myself: Wow, this lamp is beautiful, this store is good! This results in a good first impression of the store. Therefore, neon signs, every shopkeeper who has the vision to get rich deserves it!

The installation of neon signs should meet the following requirements:

Neon signs should be matched with the corresponding transformer and should not share the same circuit with other power sources.

The high-voltage wire of the neon tube should be made of high-voltage insulated wire, or bare copper wire covered with glass tube; When the wire passes through the wall, it should be installed in a double-glazed casing, and the casing should be exposed 8~8 cm on the wall; Between high-voltage lines, high-voltage lines The distance between the laying surface and the laying surface shall not be less than 5 cm, and the distance between the supports shall not be greater than the following values: 0.5 m when laying horizontally; 0.75 m when laid vertically.

The wire connections should be staggered, and the connection points should be covered with glass tubes with a length of not less than 100 mm.

The height of the neon chandelier from the ground shall not be less than 2.5 meters, and it should be reliably shielded when it is less than this height; Neon chandeliers should be hung using galvanized iron or copper wire.

The height of the neon tube from the ground shall not be less than 4 meters, and the height from the balcony, window door, and overhead line shall not be less than 1 meter.

The distance between the neon tube and flammable objects, other wiring, water pipes, gas pipes, etc. should not be less than 300 mm; The clearance distance between the iron frame and pull wire of the outdoor neon sign and the high-voltage overhead line should not be less than 2 meters.

When neon lights are installed in the window, the primary side switch between the window door and the transformer should have an interlock device.

The neon billboards at night have a nostalgic flavor. Such billboards were quite popular a few decades ago, and now they have mostly been replaced by LEDs and various large screens, but this unique style is still familiar to people.

Choosing a suitable installation method is also quite reusable. The installation method must be selected according to the characteristics of the advertising signboard and the installation environment, and the following is a list of several installation methods commonly used in the advertising logo:

1. Screw inside the bottom plate

This installation method is aimed at the identification of the metal bottom box, such as the blister word, the plane luminous word, the installation is first according to the size of the measurement in the installation wall and the identification of the metal bottom plate drill a good hole, the bottom box is fixed on the installation wall with screws, and then the word shell is installed on the bottom box with a screw.

2. Hanging type

The chain materials used in this way mainly include iron chains, steel cables, hanging fish wires, cable ties, etc., and suitable lifting materials are used according to the indoor and outdoor environment, the weight of the identification and signage production and some other special requirements. The tag light box is the use of this installation method.

3. Paste hanging type

This is also used for some fold markings, if the installation wall foundation is marble, glass, stainless steel and other installation walls that do not allow drilling, and are strong and flat, then this method is It's a good fit. First of all, accurately measure the installation position to prevent the logo from being crooked, use AB glue to stick organic edge strips or angle aluminum and other materials on the wall, and then hang the logo fold edge, fine-tune the position, and fix it with glass glue.

4. Floor-mounted

According to the design requirements, the logo can be placed in the corresponding position. Most of the metal double-sided letterings are installed in a floor-standing manner.
