Novel method for manufacturing photoelectric printing luminous tube

Abstract

The invention provides a novel method for manufacturing a photoelectric printing luminous tube. The method comprise the following steps of: manufacturing a tube cell; printing various images, characters or the combination of images and characters on the inner wall of tube cell; and finally manufacturing a luminous tube. By the method, the luminous tube is added with a plurality of additional functions of the luminous tube, and besides lighting, the light source is not the monotonic luminous tube any more in appearance and effect for luminous icons with different colors and contents, such as names, company names, blessings and the like, can also make the luminous tube possess artistic appreciation values and humanized meanings; the problem that the ink printing causes environmental pollution is solved; in addition the ink printing is of easy abrasion, and the images, characters and trademarks printed in the luminous tube manufactured by the method are never worn off, difficultly imitated, and naturally anti-counterfeited, so that the luminous tube is extremely high in practical value; and the luminous tube also widens the application field and range of the luminous tube, and besides the wide application to household lighting, commercial lighting, factory, mine and school lighting and the like, the luminous tube manufactured by the method is widely applied in various places of gift industry, advertising industry, landscape lighting and the like.

Description

technical field [0001] The invention relates to a lamp tube, in particular to a method for manufacturing a novel photoelectric inkjet coding lamp tube. Background technique [0002] Fluorescent lamps and neon lamps are pure white light or colored light, and there are no various patterns and characters on the lamp tubes. In the prior art, the new lamp tube with the patent No. 200420017867.x relates to a straight tube fluorescent lamp and a straight tube neon lamp. The lamp tube is covered with an inner glass tube, one end of the inner glass tube is closed, and the other end is open; The isolation caps at both ends of the inner glass tube form a narrow discharge cavity between the outer wall of the inner glass tube and the inner wall of the outer glass tube; the ceramic sleeve on the stem protects the electrodes from being squeezed or crushed; the inner glass The surface of the tube is coated with phosphor powder or patterns and characters made of phosphor powder, so that the...

AI Technical Summary

Problems solved by technology

Its disadvantages are: (1) There are problems in the design principle of the lamp tube in this scheme, and it may not be able to achieve real product realization, because the color of the light emitted by the inner lamp tube will be different from the light emitted by the phosphor powder coated on the outer wall of the inner lamp tube. Color mixing. Secondly, since there is a discharge cavity between the inner and outer glass tubes, there will be spectral lines of mercury and inert gas (such as argon) and a small amount of visible light, which will also mix with the luminous color of the inner lamp tube, which may eventually fail to achieve The expected effect of emitting multiple colors of light

(2) Due to the blockage of the outer glass tube and the gas light in the cavity, the lamp tube of this scheme can not improve the luminous brightness of the lamp tube, but reduces the original luminous brightness of the lamp tube

(3) The tube structure of this solution is too complicated, the production is cumbersome, the product qualification rate is not high, it is difficult to achieve mass production, and the cost is also greatly increased compared with ordinary fluorescent tubes

(4) Compared with ordinary fluorescent tubes, the lamp tube of this scheme has many accessories, and the shape and structure are difficult to replace with ordinary lamp tubes, which is not conducive to large-scale promotion and application

The lamp tube of this solution is not the same type of light source as the product of the present invention, and is not comparable. The luminous principle is quite different, and the luminous effect is also completely different. In addition to the lamp tube, a supporting control circuit is required, and the cost is also very different.
