Abstract
The invention provides a preparation technology of an LED fluorescent screen. The preparation technology mainly comprises the steps of: preparing an LED substrate; coating a fluorescent layer; and solidifying the fluorescent layer. The preparation technology is simple and easy. The prepared fluorescent layer on the surface of the LED fluorescent screen is uniform. The fluorescent color temperature of the LED is normal. The production cost is low, and the preparation technology is suitable for large scale production and manufacture.
Description
Technical field
The present invention relates to sealing adhesive process, particularly relate to a kind of preparation technology of LED fluorescent plate.
Background technology
LED fluorescent plate another name has again fluorescent plate, LED fluorescent writing board, electronic fluorescent screen, the sub-fluorescent plate of LED electrical, the sub-billboard of LED electrical.Its principle writes on LED fluorescent plate with e-Pointer exactly, plugging in, by the LED of fluorescent plate side highlighted paster 5050 light source irradiation on acrylic panel or ultra-clear glasses panel, the word write out by e-Pointer sends different colours, with the effect of different mode, very attracting eye.
Summary of the invention
The invention provides a kind of preparation technology of LED fluorescent plate.For realizing object of the present invention, technical scheme of the present invention is as follows:
A preparation technology for LED fluorescent plate, is characterized in that, its concrete steps are:
(1) raw material of LED-baseplate are put in the mould of LED-baseplate, then, formed by uniform temperature sintering, then LED-baseplate is prepared in demoulding process after cooling;
(2) in LED-baseplate, fluorescence coating is applied again;
(3) irradiate the LED-baseplate having applied fluorescence coating, the light source of irradiation adopts ultraviolet and/or infrared ray, thus reaches solidification fluorescence coating.
Preferably, step (2) coating fluorescence coating adopts fluorescent liquid spray gun to be evenly ejected in LED-baseplate, and fluorescent liquid is the mix preparation of fluorescent material and UV curing agent.
Preferably, step (3) irradiation time is 260-320s.
Beneficial effect: the preparation technology that the invention provides a kind of LED fluorescent plate, its key step comprises preparation LED-baseplate-coating fluorescence coating-solidification fluorescence coating etc., this manufacturing process is simple, the LED fluorescent plate surface fluorescence layer of preparation is even, LED fluorescence colour temperature is normal, production cost is low, is applicable to large-scale production manufacture.
Embodiment
The technological means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the present invention further.
A preparation technology for LED fluorescent plate, is characterized in that, its concrete steps are:
