Description

Uv light emitting board material

The present invention relates to an advertising material made using a light emitting material to display pictures and texts, and more particularly, to an advertising sign material using the property that ultraviolet light emits a different color depending on the phosphor material.

Conventional signage technology injects gas into a flex sign or neon tube that uses a fluorescent lamp as a back light to display pictures and characters, and injects a gas that emits a different color or applies a phosphor to Phosphors were emitted by an ultraviolet excitation method and used as an advertising display tube.

In other words, neon is injected into the tube or red phosphor is applied to emit red light, helium is injected or yellow phosphor is applied to emit yellow light, and mercury or blue phosphor is applied to emit blue light.

However, the flex display tube using the conventional fluorescent lamp as the back light is dark and the effect of advertisement is low, and the display tube using the neon tube is fixed in size, and the power consumption is increased by using high voltage to discharge the gas, and the gas is charged in the tube. Therefore, there are many problems such as manufacturing cost and production complexity.

On the other hand, Figure 1 is a signboard using a conventional fluorescent lamp is a typical non-luminescent flex signboard using a fluorescent lamp as a back light on the advertising surface printed with ink to shine the signboard by the light of the fluorescent lamp.

Referring to FIG. 1, the conventional flex signboard is composed of a front face 1, a printed layer 2, a side face 3, and a fluorescent lamp 4.

The light emitted from the fluorescent lamp 4 illuminates the paint print layer 2, thereby allowing signage advertising.

Such a signboard can be produced without restriction on the length and width of the advertisement, and it has the advantage of free expression of pictures and contents and a semi-permanent lifespan. The colors of letters and pictures are not clear, so they are hard to see at a distance.

2 is a conventional neon sign is a self-luminous method in which ultraviolet rays are generated by gas discharge when a high pressure is applied by enclosing a gas of a predetermined pressure in a tube and using the same, to emit phosphors.

Referring to FIG. 2, a conventional neon sign is composed of a front glass 1, a phosphor 2, an electrode 3, and a gas 4.

The neon sign emits ultraviolet rays by applying a high voltage of about 15 kV or more to the electrode 3, and these ultraviolet rays excite the phosphor 2 and emit light. These neon signs are self-luminous, so they are stable in color, have the highest visibility in the night, and can be displayed dynamically with blinking effects, but the production cost is very high, the power consumption is high, and there is a leakage element due to high voltage.

Accordingly, the present invention has been made in view of the above-mentioned conventional problems and solves the above problems, and an object of the present invention is to provide a material for realizing a billboard having high brightness by self-emitting a phosphor printed on the front surface with low power consumption. In providing.

Another feature of the present invention is a billboard material which is at least suitable for indoor and outdoor billboards.

In order to achieve the above object, the characteristics of the ultraviolet self-luminescent billboard material according to the present invention are generally easy to obtain UV generation, which is an energy source that forms letters or pictures on the front surface and emits phosphors, not by gas discharge. UV lamps, and UV reflectors were used to reflect the UV rays emitted from the back.

Referring to FIGS. 3 and 4, the present invention is composed of a front surface 1, a fluorescent layer 2, a side surface 3, an ultraviolet lamp 4, an ultraviolet reflector 5, and a separator 6. .

The ultraviolet self-luminescent billboard uses the light emitted when the ultraviolet wavelength emitted from the ultraviolet lamp 4 returns to the ground state after exciting the fluorescent layer 2. At this time, the ultraviolet reflector 5 reflects the ultraviolet rays emitted from the ultraviolet lamp 4 to the rear surface to maximize the efficiency of the ultraviolet lamp.

In addition, each UV lamp is matched to each letter or picture, and the UV lamp 6 is turned on and off by inserting a separator 6 made of a material through which UV light does not pass between the UV lamp and the lamp. It can give flickering and dynamism.

The UV self-emitting billboard material of the present invention constructed and operated as described above is a self-luminous billboard and has the advantages of both billboards and neon signs, and various effects of the present invention are as follows.

First, the self-luminous method using phosphors has a higher luminance than a general flex billboard, so the advertisement effect is excellent and the view is very stable.

Second, compared to neon signs that emit high phosphors by applying high voltage to the gas, the use of ultraviolet lamps can reduce power consumption, and there is no limit on the manufacturing size as in flex billboards, and it is very easy to maintain and repair. .

Third, the present invention can directly reduce the production cost of the billboard of the same brightness by producing the ultraviolet light directly from the ultraviolet lamp, not the way of generating ultraviolet light by the discharge of the gas like a general neon sign. In addition, the use of mirror-like UV reflector maximizes the efficiency of UV lamps.

Fourth, the neon sign maintains a high degree of vacuum in the glass tube to generate ultraviolet rays, and then inserts a discharge gas of a certain pressure to apply high voltage to generate ultraviolet rays, and the phosphor emits light by the ultraviolet rays. It is very inexpensive in terms of production cost, and it is possible to maintain and repair the advertisement board just by replacing the UV lamp, because the phosphor can emit light with only an ultraviolet lamp without maintaining the cost. Neon sign has a limit on the size of the billboard production, but the present invention is not limited to the size of the production.

Fifth, the present invention may be installed between the UV lamp and the UV lamp by the separator which does not pass through the ultraviolet light of ordinary plastic or glass material and by flashing these UV lamps can be flickering advertising surface like neon signs and give a sense of dynamism.
