Tube coloring technology for colorful lamp tubes

Abstract

The invention relates to a tube coloring technology for colorful lamp tubes and particularly relates to a process method for manufacturing a colorful fluorescent lamp tube, which belongs to the lamp tube coloring technology. Most of traditional colorful energy-saving fluorescent lamps are provided with colorful lamp tubes and are crispy in material, large in breakage rate, low in manufacturing pass percent, large in processing difficulty, difficult in quality control, inconvenient in transportation and high in price. Meanwhile, during the lamp manufacturing process in the prior art, fluorescent powders are coated unevenly and most of the powders are accumulated. According to the technical scheme of the invention, ethyl orthosilicate, ethanol or methanol, coloring salts, water, glucose, glacial acetic acid, nitric acid and normal butanol are adopted as main raw materials. After that, the materials are coated outside a colorless transparent tube by adopting the specific process, and then a colorful fluorescent lamp tube can be manufactured. The prepared colorful fluorescent lamp tube is strong in color adsorption force, not easy to fade, long in service life, high in finish degree, and resistant to the wind and the sunshine.

AI Technical Summary

Problems solved by technology

[0002] At present, most of the traditional color energy-saving fluorescent lamps are made of colored lamp tubes. Colored lamp tubes are made by adding chemical pigments to ordinary lamp tubes, resulting in brittle materials of finished lamp tubes, large breakage, low manufacturing pass rate, and difficult processing. The quality is difficult to control, which is not conducive to transportation. The price of the finished color lamp tube is three to four times that of the transparent lamp tube. In the process of making the lamp, the fluorescent powder is coated because the lamp tube is opaque, and the inside of the energy-saving fluorescent lamp cannot be observed. powder layer, resulting in uneven powder layer and a lot of powder accumulation. At the same time, in the process of sealing and exhausting the lamp tube, there is a lot of air leakage, and the vacuum degree is difficult to guarantee. The photoelectric parameters of the lamp tube cannot be guaranteed. The pass rate is only equivalent to about 30%-40% of the pass rate of ordinary energy-saving fluorescent lamps

Because the quality is difficult to control, the service life is short, the use cost is high, the photoelectric parameters cannot be guaranteed, and effective after-sales service cannot be implemented for consumers

[0003] There are also some colored light bulbs or colored fluorescent lamps that are coated with colored phosphors, but the manufacture of colored phosphors is difficult, costly, poor in quality, unstable in luminescence, and short in life
