Description

Colorful fluorescence radiation display device

But the utility model relates to a kind of making of luminous display unit.

Luminous display unit purposes in direction board, billboard is extremely many, the place of using is also extremely extensive, as neon bulb and lamp box is the most frequently used luminous display unit, with regard to neon bulb, the history that last 100 years has been arranged, but because neon bulb damages (slender glass tube of neon bulb is very easily damaged, High-Voltage Electrical Appliances part voltage height also fragile) easily, often see easily that the advertisement neon bulb of incomplete or scarce stroke declares publicly in public, this quite is repugnant to the eye.Also because the cost height of neon bulb, complex manufacturing technology, the maintenance cost of neon bulb and the cost when using are also higher, use the neon bulbs may not be most economical in many occasions.Advertising lamp box is another big class luminous display unit, and its brightness is not so good as neon bulb, and very desirable in the effect of performance colourful transparent, and the energy consumption height, and every square metre needs the fluorescent tube with 200W power.In the field of luminous display unit, also the end see have can reach high-level efficiency, energy consumption is little, easy to maintenance, use cost is low, brightness is high, the colored abundant luminous display unit of performance.

The purpose of this utility model provides a kind ofly can reach high-level efficiency, energy consumption is little, easy to maintenance, manufacturing cost and use cost is low, brightness is high, the colored abundant luminous display unit of performance, is used for substituting a large amount of now neon bulb display device and lamp box display device of using.

The purpose of this utility model reaches like this: comprise panel and light source composition, panel is that the mixed resinous coat of coated fluorescence radiation is made on the picture and text of plastic base, and the mixed resin of fluorescence radiation is mixed afterwards by ultraviolet light polymerization photoresist and fluorescent pigment.

Secondly the preferred ultraviolet source of light source described in the utility model, be the cold light lamp light source.

Colorful fluorescent display apparatus of the present utility model has many characteristics: this is a kind of ideal device of alternative neon bulb.Because the luminescent material of this device has the luminosity height, light is soft, advantage such as beautiful in colour, color can regulate arbitrarily, colored transparency is good, Master Cost is low, easy to prepare, maintenance cost is extremely low.It is the best invention that modern advertising replaces neon bulb.Fluorescent pigment be a kind of under natural light, general light source activation or ultraviolet excitation the material of emitting fluorescence, can half active illuminating.

The utility model utilizes the reasonable assembly of fluorescent pigment and light-cured resin, because the thixotropic property of UV-cured resin is good, processing and fabricating is easy, and resin itself keeps good shape, and ultraviolet light makes its rapid curing.Because the cooperation of fluorescent pigment can be regulated arbitrarily, so the utility model light-emitting device tone can be regulated arbitrarily.This does not accomplish on neon bulb.Field of employment of the present utility model comprises the direction board that various luminous display ads, guideboard, commercial advertisement and various public place use.

The utility model is described in further detail below in conjunction with accompanying drawing with by embodiment:

Fig. 1 is a structural representation of the present utility model

As shown in the figure, be shaped on light-cured resin and fluorescence radiation pigment mixed and literal or the image 2 retouched on the panel.Ad hoc have light-emitting device or a burst of ultraviolel device 1, consider launching efficiency, with the burst of ultraviolel device is excellent, described burst of ultraviolel device is uviol lamp, as medical or sterilization uviol lamp commonly used, comprise the ultra-violet light-emitting fluorescent tube and start fairing, the power of uviol lamp can be much lower more than existing lamp box, can efficiently excite the lamp box of 0.3m2 area as the fluorescent tube of 10W, and need only the work of light source interruption, for example, uviol lamp work ten minutes, can make fluorescence radiation continue several minutes, the addition that will look fluorescent pigment certainly decides, and the addition of general fluorescent pigment is more, when the coating of promptly mixed pigment has the above thickness of 0.2mm, can control the interruption work of uviol lamp, be interrupted the control of power supply and generally adopt electronic circuit, promptly be interrupted switch control uviol lamp working power by one.Selectable scheme is extremely many, the logical circuit that constitutes as Programmable Logic Controller, by counter etc., special-purpose timing chip, microprocessor or the like, circuit connects and the break-make of control controllable silicon or switching tube, solid-state relay thus, thus the work of control uviol lamp power supply.Seldom give unnecessary details herein.

Typical photoresist is the constituent of oleic series resin, and its composition comprises:

1. acrylic acid polycarbamate, epoxy acrylic resin, polyester acrylate

2. polyvalent alcohol polyfunctional acrylic ester photocrosslinking agent

3. light trigger: acetophenone derivs, benzil dimethyl ether, arone compounds, thioxanthene quinones, organometallics etc.

If add some thickening materials, add the external form in man-hour at light-cured resin, before the resin photocuring, can keep a period of time constant, resin can forever keep adding the shape of character in man-hour through ultraviolet ray irradiation back generation instaneous polymerization.

Photoresist and fluorescent pigment are promptly become the mixed resin of colorful fluorescence radiation after mixed, and some typical proportions (weight) are as follows:

1. acrylic acid polycarbamate 45-80%

Trimethylolpropane triacrylate 5-10%

Pentaerythritol triacrylate 5-8%

Hexanediyl ester 5-8%

Tri (propylene glycol) diacrylate 2-5%

Two-methyl-2-morphine quinoline (4-methylthio phenyl)-1-acetone 5-10%

1-hydroxyl cyclohexyl Benzophenone 1-3%

Thickening agent 0.5-4%

Fluorescent pigment 1-10%

2. acrylic acid polycarbamate 25-70%

Epoxy acrylate 10-15%

Trimethylolpropane triacrylate 5-8%

Pentaerythritol triacrylate 5-8%

Hexanediyl ester 2-5%

Tri (propylene glycol) diacrylate 5-10%

Two-methyl-2-morphine quinoline (4-methylthio phenyl)-1-acetone 1-30%

1-hydroxy cyclohexyl phenylketone 0.5-2%

Thickening agent 0.5-4%

Fluorescent pigment 1-10%

Fluorescent pigment is commercially available inactive pigment for well, as fluorescein, purple, Huang, green, black etc.

The panel that has the mixed resin demonstration of colorful fluorescence radiation picture and text is made as follows: the base material of panel is selected transparent or semitransparent plastic plate or lamp house cloth for use, it is best to make a two-sided lamp box, uviol lamp places lamp box inside, the colorful fluorescence radiation of coated mixes resin again after forming the picture and text profile on the panel, and the thickness that coated is certain is typically got 0.2-1mm.The PS of substrate 4 preferably clears, PMMA sheet material, cutting also can on substrate.Directly on substrate, print, write picture and then the coating thickening also can be obtained a kind of good luminous display device with the mixed resin of colorful fluorescence radiation.The formation of picture and text profile can form with the method that posting in time is carved characters.

The utility model also can be used the cold light light source, and as daylight lamp, black lamp, these do not exceed scope of the present utility model.

Luminous display unit is generally lamp box 5, as daylight lamp box roughly the same commonly used, all makes picture and text 2 on the two sides of lamp box, is fluorescence radiation display board 3.With rotary lamp box also is good embodiment, tubular light source 2 is erected in the middle of the lamp box, luminous display surface makes cylindric or rotary body (also can be the rectangle lamp box), light source does not rotate in the middle of lamp box, and the cylinder that luminous display surface is made is around vertical tubular light source rotation, as rotation dynamic advertising, because its light efficiency height, effective, can avoid complicated wiring, also general daylight lamp box is difficult to realize.
