The neon lamp is a cold cathode glow discharge tube. Its radiation spectrum has a strong ability to penetrate the atmosphere. The color is bright and colorful, and the luminous efficiency is obviously superior to that of ordinary incandescent lamps. Its line structure is rich in expression. It can be processed into any geometric shape to meet the design requirements, and it can be welcomed by electronic program control, variable color patterns and characters.
The bright, beautiful and dynamic characteristics of neon lights are irreplaceable by any electric light source at present, and they are leading the way in the emergence and competition of various new types of light sources.
Since the neon lamp is a cold cathode glow discharge, a quality qualified neon lamp can have a life of 20,000-30,000 hours.
With the rapid development of China's economy, the varieties and specifications of neon lights have been basically serialized, and they can be used for various purposes. The quality has gradually moved closer to the international level. As China's accession to the WTO and the international level will become more and more different. Small, in the near future, it will surely catch up with the international advanced level. However, under the current market competition conditions, there are indeed a few manufacturers lacking integrity, and in some cases, users do not understand the performance and quality of neon lights, producing and producing inferior products. Dumping at a low price in the market affects the reputation of neon lights.
In order to familiarize the big users with neon lights and learn about neon lights, we will briefly introduce some neon varieties, specifications and main equipment for making neon lights to help users identify the pros and cons of "neon lights".
The main components of the neon:
1. Neon tube:
(1) According to the specifications: there are thicknesses of 6, 6, 7, 8, 8, 9, 10, 15, 15, 18, 20m/m.
(2) According to the glass material: 1 Sodium glass tube (or lime glass tube) This glass tube has poor stability, is easily deteriorated after moisture, and is effluent (weathering), and the fastness is easy to burst. At present, about 80% of such materials are used in China. 2 Lead glass tube (also known as red glass tube) has better thermal performance, mechanical properties, electrical properties, chemical stability, vacuum performance and optical properties than soda glass. Its weather resistance and service life greatly exceed that of soda glass. Most of the GMs are lead glass tubes. The current usage in China has reached 20-30%. For those who are looking for good quality, users use lead pipes to make neon lights. Lead glass is divided into lead content: heavy lead glass, medium lead glass and light lead glass. 3 colored glass tube, which has been filled with dye when drawing the glass tube, and the produced glass tube has been colored glass tube.
(3) Applying fluorescent material in neon tube: 1 Most of the neon tubes currently used are sprayed with “ordinary phosphorsâ€. These powders are cheaper and generally meet various color requirements. 2 "three primary color" phosphors (also known as rare earth phosphors) have better brightness, color and freshness than ordinary phosphors.
(4) The process of spraying the phosphor is divided into two types: water coating and gel coating. 1 The water is coated with alcohol, and the ketone-solvent mixed phosphor is sprayed on the inner wall of the tube to let it dry naturally. 2 The glue coating is sprayed with the glue mixed with the phosphor, and then dried in an oven, the viscosity and the fastness are much better than the water coating powder tube.
At present, most countries in the advanced countries use three-primary plastic coated lead glass tubes to make neon lights. Some neon tubes have been used in some countries in China.
2, neon transformer
(1) Neon leakage magnetic transformer, also known as inductive transformer, iron core transformer, its characteristics are: good reliability, high brightness of the load lamp, consistent light color, long life, shortcomings are cumbersome, currently foreign and Shanghai outdoor Most of the neon lights use this type of transformer. Inductor transformer specifications are: 3KV, 6KV, 9KV, 12KV, 15KV, 18KV.
(2) Electronic transformer (also called high-frequency cold-start tubular discharge lamp (neon) electronic converter or neon power supply) has the advantages of light weight, convenient manufacture and metal material saving. At present, the quality of domestically produced electronic transformers is stable and certain The scale, some of which are also exported in batches. However, the brightness of electronic transformers produced by many units does not reach the brightness, and it is a bit dwarfed when used outdoors. The electronic transformer is divided into two types, DC and AC. The DC electronic transformer often produces a dark condition due to the single-way conduction. Moreover, because the output frequency of the electronic transformer is affected by the length of the load lamp, in the same neon lamp, the unevenness of the lamp color may occur due to 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 the electronic transformer are: 40W, 60W, 80W, 100W, etc., also known as 4 meter machine, 6 meter machine, 8 meter machine, 10 meter machine, 12 meter machine, etc. It is also possible to actually produce an electronic transformer that meets the requirements for neon use, but the price will be close to the price of the inductor transformer. In order to obtain low market share and gain market share, some manufacturers sacrifice the brightness, reliability and longevity of the neon lamp to obtain Market profit.
3, the program controller points:
(1) Ordinary electronic program controller:
(2) Gradient electronic program controller:
4, neon high voltage line points:
(1) Ordinary high-voltage lines, that is, plastic high-voltage lines, such high-voltage lines are cheap, but plastics are prone to aging, and plastics will soon age and cause fires, etc., and the safety is poor.
(2) Silicone rubber insulated high voltage line is the ideal neon light connection line with strong safety and good reliability.
The above is the main other components that make up the neon lights. From the above, neon lights, like other products, vary greatly in terms of variety, specifications, and quality.
When users choose neon production units, they should also understand their production strength, processing technology and after-sales service in place. For larger neon projects, they should make detailed quotations and verify them. If conditions are met, they should be in accordance with industry standards. Carry out the acceptance, not only to see the total price is cheap, but also depends on what kind of quality and service they provide to the user.
