At night, the streets and alleys are full of brilliant neon lights, and the signboards of many shops are composed of heavy rainbow light letters, so how to do neon light letters?

1. The production of neon lights is inseparable from the cdr software. The first step is to prepare the cutting lines (patterns) we need in the cdr software, note the color and the thickness of the light strip (6-8mm), and then 1 :1 Adjust the size of the pattern and font.

2. The factory will make the cutting and engraving production documents according to the documents we have prepared. It is necessary to cut the bottom plate according to the outline or the whole board, and then mill the groove according to the lines of the document.

3. The production of heavy rainbow lamps. The production process of heavy rainbow lamps is basically the same whether it is an open tube, a pink tube or a colored tube. They all need to be formed by glass tubes.

Processes such as sealing electrodes, degassing by bombardment, filling with inert gas, sealing vent holes, etc.

4. The workers install the lamps according to the lines of the milling slots, and the colors are installed according to the requirements: after the lamp strips are installed, the wires will be soldered together, and the power will be tested to see the effect, and the heavy rainbow lights will be made. up

How is the Lei Hong Lantern made?

In the production process of Leihongdeng luminous characters, the key step is the production of Leihongdeng. The production process of

Leihongdeng is as follows:

1. Glass tube forming

The production staff goes through the special fire head along the outline of the pattern or text, and burns, roasts, and bends the straight glass tube into a pattern or text. The level of the production staff can be seen with the naked eye. The light made by the low-level staff The pipe is prone to unevenness at the turning, too thick or too thin, inner wrinkles, deviations and uneven planes, etc.

2. Sealing electrodes

In the process of connecting the bent lamp tube to the electrode and the exhaust hole through the burner, the interface must not be too thin or too thick, and the interface must be completely melted, otherwise slow air leakage will easily occur.

3. Bombardment degassing

This step is the key to making heavy rainbow lamps. The electrodes are bombarded with high-voltage electricity, and the electrodes are heated to burn the invisible water vapor, dust, oil and other substances in the electrodes of the lamp tube.

In the process of removing these harmful substances and pumping the glass tube into a straight space, the key to this step is to control the temperature. If the bombardment degassing temperature cannot be reached, the above harmful substances will not be completely removed, which will directly affect the quality of the lamp tube. Excessive bombardment degassing temperature will cause excessive oxidation of the electrode, resulting in an oxide layer on the surface, resulting in a decrease in the quality of the lamp tube.
