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 reduc...

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.

Example Embodiment

[0023] A new type of photoelectric inkjet lamp manufacturing method, the process steps adopted are as follows:
[0024] (1) Glass tube cleaning and drying (100℃); chemical polishing (potassium permanganate solution or low-concentration hydrofluoric acid solution) makes the inner surface of the glass tube smooth and clean; electrostatic treatment (eliminate negative charge) promotes the phosphor layer (The slurry has a weak negative charge) Bonding with the glass tube.
[0025] (2) The inner wall of the rare earth three-color phosphor slurry glass tube is sprayed, heated and dried (100℃-150℃) to form a powder tube.
[0026] (3) Polymer organic protective film materials for transitional isolation (such as: polyethylene phthalate PET, hydrogenated nitrile rubber HNBR, etc.), that is, the selection and liquefaction of photolithographic mask materials (heating at 300℃- -400℃); Carry out the second coating (spun film method) and cool to form the film;
[0027] (4) Professional software (such as CorelDRAW) edits vector graphics, text, numbers, trademarks, etc.; uses laser equipment to perform graphic processing on the inner wall of the glass tube (also called photolithography: coating vaporization process) to form hollow graphics; Electrochemical treatment (ultrasonic cleaning to remove dust from incomplete photoetching), mechanical polishing to make the image and text traces in the hollowed area neat and clear;
[0028] (5) Configure rare earth single-color phosphor paste (cyan, magenta, yellow or red, green, blue, etc.); the third spraying, heating and drying (100℃--150℃);
[0029] (6) High temperature decomposition and vaporization of chemical substances such as adhesives for lamp making, transition protective film isolation materials, etc. (500°C-600°C); at the same time, the residue of the isolation material and the excess rare earth single-color phosphor layer at the non-hollowed part are released together, Mechanical blower discharge, recycling process; obtain the finalized spray code powder tube;
[0030] (7) Use the finalized spray code powder control as the finished lamp tube.
[0031] Repeat steps (3) to (6) to obtain code-spraying shaped powder tubes with multiple luminous color materials. Enter the lamp manufacturing process to complete the entire manufacturing process of photoelectric inkjet light source products.
[0032] The finished lamp tube is excited by ultraviolet rays to emit light at the same time to form product logos, text, numbers, patterns, etc., with different colors and different from the color of the lamp itself.
[0033] Omitting the steps (3) and (5) to make a light tube with transparent and hollow graphics and text effects, there are also good different effects.
[0034] (1) The glass tube is cleaned, dried, and then polished to make the inner surface of the glass tube smooth and clean; electrostatic treatment to eliminate negative charges;
[0035] (2) Use rare earth three-color phosphor paste to spray the inner wall of the glass tube, and heat and dry at 100℃~150℃ to form a powder tube;
[0036] (4) Then, perform photo-etching graphic processing on the inner wall of the glass tube to form a hollow graphic;
[0037] (6) At 500℃-600℃, it will be vaporized and discharged by mechanical blowing to form a transparent, hollowed out graphic powder tube;
[0038] (7) To make finished lamp tubes.
