(1) Neon luminous characters leakage transformer, (also known as inductance transformer, iron core transformer) is characterized by good reliability, high brightness of the load tube, consistent light color, long life, and the disadvantage is that it is relatively bulky. It is currently abroad and Shanghai Most of the outdoor neon luminous characters use this kind of transformer.
The specifications of the inductance transformer are: 3KV, 6KV, 9KV, 12KV, 15KV, 18KV.
(2) Electronic transformers (also known as high-frequency cold-start tubular discharge lamps (neon luminous characters) electronic converters or neon luminous characters power supply) have the advantages of light weight, convenient manufacturing, and saving metal materials. At present, the quality of domestically produced electronic transformers It is stable and has a certain scale, some of which also export in batches. However, the brightness of electronic transformers produced by many units is not as bright as it should be, and it is a bit inferior when used outdoors.
There are two types of electronic transformers: DC and AC. Because of the unidirectional conduction of DC electronic transformers, the lamp tube tends to be bright and dark at the other end. And because the output frequency of the electronic transformer will be affected by the length of the load lamp, in the same neon light, the lamp color will be uneven due to the difference in the length of each lamp. In order to reduce costs, some manufacturers are reluctant to use high-quality and high-quality electrical components, and the processing technology is simple, so the reliability is poor and the life is short.
The specifications of electronic transformers are: 40W, 60W, 80W, 100W and other specifications, and there are also 4 meters, 6 meters, 8 meters, 10 meters, 12 meters, etc.
It is also possible to truly produce electronic transformers that meet the requirements for the use of neon luminous characters, but the price will be close to that of inductive transformers. In order to compete at low prices and gain market share, some manufacturers sacrifice the brightness and reliability of neon luminous characters. , Life span to obtain market profits.
3. The program controller is divided into: (1) Ordinary electronic program controller:
(2) Gradual electronic program controller:
4. Neon luminous characters high-voltage line points:
(1) Ordinary high-voltage cables, namely plastic high-voltage cables, are cheap, but plastics are prone to aging. Soon after outdoor use, the plastics will age and cause fire, etc., and their safety is poor.
(2) Silicone rubber insulated high-voltage wire is the ideal neon light word connection wire at present, with strong safety and good reliability.
