Embodiment 1

[0032] Embodiment 1 (no defoamer):

[0033] Varnish 55.87%, fluorescent powder 27.93%, white oil 5.03%, open oil water 11.17%.

Embodiment 2

[0034] Embodiment 2 (with defoamer):

[0035] Varnish 63.49%, fluorescent powder 27.51%, white oil 6.35%, open oil water 2.12%, defoamer 0.53%.

Embodiment 3

[0036] Embodiment 3 (with defoamer):

[0037] Varnish 60.24%, fluorescent powder 30.12%, white oil 5%, boiled oil 2.84%, defoamer 1.8%

[0038] To sum up, no matter whether defoamer is added to the ink composition or not, but the produced ink is screen-printed on the film, and then the film is pasted on the LED digital tube, so that the effect of changing the blue light of the LED digital tube to white light can achieve good results. .

[0039] After the ink is proportioned according to the above-mentioned embodiments, the film for making the blue light of the LED digital tube into white light can be produced.

[0040] The specific process of producing the film that turns the blue light of the LED digital tube into white light is as follows:

[0041] Tape preparation—automatic printing—the first thermal curing—cutting the tape—semi-automatic screen printing phosphor—the second thermal curing—brushing 3M glue—drying 3M glue—attaching release film—printing.

Abstract

The invention discloses a pad pasting capable of changing blue light of an LED nixie tube into white light, and a manufacturing method thereof. One ingredient of the pad pasting is a printing ink. The printing ink comprises following components, by mass, 45 to 70% of gloss oil, 20.3 to 35% of a fluorescent powder, 5 to10% of white oil, 1.03 to 15% of a diluent, and a small amount of an antifoaming agent. The invention also discloses the manufacturing method of the pad pasting. The manufacturing method comprises following steps: preparation of tape materials; automatic printing; first thermocuring, cutting of tape materials; semi-automatic silkprinting of the fluorescent powder; second thermocuring; coating of 3M glue; drying of 3M glue; pasting of release liner; and punching. The pad pasting is pasted on to the LED nixie tube, and is capable of changing blue light of the LED nixie tube into white light; compared with a traditional LED nixie tube which is prepared by filling the LED nixie tube with the fluorescent powder directly, light of the LED nixie tube is more uniform. In addition, the manufacturing method is capable of reducing waste of the fluorescent powder and cost.

Description

technical field [0001] The invention relates to a device for changing the blue light of an LED digital tube to white light, in particular to a fluorescent film capable of changing the color of the digital tube and its manufacturing process. Background technique [0002] At present, the production of the film of the known LED digital tube is to use transparent PC material to screen-print the content with ink, and then screen-print 3M glue after drying, and then punch the finished product according to the customer's requirements. However, such a transparent film can only emit the most original light of the LED when it is pasted on the LED display. [0003] Another technology is to inject phosphor powder into the LED light-emitting tube to turn blue light into white light. However, the cost of phosphor powder in this process is high, the waste is large, and the phosphor powder is injected unevenly, resulting in different shades of light emitted by the LED illuminant, which ...
