Manufacturing method of color lamp tube

Abstract

The present invention provides a manufacturing method of a color lamp tube, belonging to the technical field of lamps. The problem is solved that production quality is low in the prior art. The manufacturing method comprises the following steps of: S1, proportioning: components in ratio by percentage by weight comprise 50% of SiO2, 10% of AL2O3, 20% of Na2O, 10% of BaO and 10% of TiO2 in the proportioning process step; S2, mixing: materials in the S1 are put into a material mixing box to perform mixing; S3, melting: the mixed materials in the S2 are put into a melting furnace for melting; S4,molding: liquid melted in the step S3 is injected into a forming model and performs cooling demolding after forming to form a tube body; S5, spraying: color coating is performed sprayed to the surfaceof the tube body through a spraying device; S6, drying; and S7, assembling. The production quality can be improved.

Description

technical field [0001] The invention belongs to the technical field of lamp manufacturing and relates to a method for manufacturing a colored lamp tube. Background technique [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.

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 processing process of the colored lamp tube The pass rate in the lamp is only equivalent to about 30% to 40% of the pass rate of ordinary energy-saving fluorescent lamps.

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

Some colored light bulbs or colored fluorescent lamps are coated with colored phosphors, but the manufacture of colored phosphors is difficult, high in cost, quality and unstable in luminescence, and short in life
