The present invention relates to a luminescent signage, and more particularly, to a luminescent signage for easily identifying the signboard contents even in a space without light using a photoluminescent material.

Signboards are typically installed on the exterior walls or entrances of buildings to serve as a means of advertising a company or shop name or merchandise. A typical signage is constructed by attaching, for example, a flexible sheet of paper to the front of the frame constituting the main body and printing or affixing advertising text such as desired text or figures on it.

In particular, various methods have been proposed for identifying signs at dark nights. The most typical example is displaying advertisements on translucent panels and installing lighting fixtures inside the frame, thereby displaying the advertisements by the light emitted from the lighting fixtures. Way. In addition, there is a method to identify the signboard using a separate lighting fixture installed outside the general signboard.

However, the first method has a weakness in that the light transmittance of the signboard panel is not excellent in luminance characteristics, and a fluorescent lamp having a large power consumption is required to obtain a desired luminance. In addition, there is a disadvantage that the identification power is not excellent because it is not a method by the light emission of the signboard itself by the second method.

FIG. 1A is a plan view showing a photoluminescent signboard according to a preferred embodiment of the present invention, and FIG. 1B is a cross-sectional view taken along the line I-I of FIG. 1A.

1A and 1B, the photoluminescent signboard according to the present embodiment includes a cover panel 10 having a groove 11 etched on the back surface, a paint layer 20 applied to the groove 11, and a cover panel ( 10 includes a photoluminescent part 30 formed on the back surface.

The cover panel 10 is etched into the groove 11 is a character or figure to be represented by the signboard on the back. In addition, the cover panel 10 is preferably made of a transparent resin resin such as soft or hard vinyl chloride resin (PVC) or polycarbonate. Thus, when the cover panel 10 is viewed from the front side, a character or a figure represented by the groove 11 etched on the back surface of the cover panel 10 may be sufficiently recognized. However, even if the material is not completely transparent, an opaque panel may be employed within the scope of identifying the label contents. In addition, the present invention is not limited to the pattern material, but various modifications may be made within the object of the present invention.

The paint layer 20 is applied to the groove 11 formed in the cover panel 10 to express a predetermined color to enhance the identification of the sign. Preferably, the paint layer 20 uses a metal paint excellent in color development, and is applied according to a conventionally known method.

The photoluminescent unit 30 is composed of a plate material made of a known photoluminescent material that absorbs light energy radiated from the outside and gradually emits light having a unique wavelength over a long time. The photoluminescent material is a material obtained by repeating an absorption-accumulation-luminescence process. More specifically, the photoluminescent material may include a photoluminescent emitter, a binder for coupling the photoluminescent emitter particles, and an additive. Preferably, the photoluminescent unit may be configured as a rectangle having a predetermined size.

Preferably, the photoluminescent signage according to the present embodiment may further include a protective coating part 60 formed on the photoluminescent part 30. The protective coating unit 60 protects the photoluminescent unit 30 from external stresses such as moisture or ultraviolet rays, which act as elements for reducing the light resistance of the photoluminescent unit 30.

The photoluminescent signage having the above configuration receives natural light from the sun during the day, accumulates light in the photoluminescent part 30, and emits light having a unique wavelength in the photoluminescent part 30 at night when no natural light exists. Therefore, the signboard can be identified at night.

FIG. 2A is a plan view illustrating a photoluminescent signboard according to another embodiment of the present invention, and FIG. 2B is a cross-sectional view taken along the line II-II of FIG. 2A. 2A and 2B, the same reference numerals as in the previously shown drawings indicate the same members having the same function and detailed description thereof will be omitted.

2A and 2B, the photoluminescent signboard according to the present embodiment further includes a light guide plate 40 formed on the rear surface of the light emitting unit 30 and a light emitting member 50 installed around the light guide plate 40.

The light guide panel 40 evenly radiates the light supplied from the light emitting member 50 provided on at least one side to the inside of the light guide plate 40, that is, the photoluminescent part 30. Therefore, the light emitted from the light emitting member 50 passes through the light guide plate 40 and is incident in the direction of the cover panel 10, and part of the light is absorbed by the photoluminescent plate 30. In addition, it is preferable that, for example, a reflecting portion 41 provided periodically with a "V" cut structure is formed near the rear surface of the light guide plate 40 to increase the light reflection efficiency in the direction of the cover panel 10.

Preferably, the light emitting member 50 may use a Cold Cathod Fluorescent Lamp (CCFL) or an External Electrode Fluorescent Lamp (EEFL) that is disposed to correspond to the side surface of the LGP 40. . In addition, the present invention is not limited to this configuration, and is disposed to correspond to at least one light emitting diode (LED) (not shown) or side surface of the light guide plate 40 disposed on at least one side of the light guide plate 40. An electroluminescent element (EL) (not shown) in the form of a strip may be used as the light emitting member.

On the other hand, the photoluminescent sign according to the present embodiment may also include a protective coating (60). The protective coating unit 60 is disposed on the rear surface of the light guide plate 50 to protect the light guide plate from external stress.

The photoluminescent signage having the above configuration accumulates natural light during the day by the photoluminescent unit 30 or accumulates the light emitted from the light emitting member 50 at night. Thereafter, even when the light emitting member 50 cannot be used due to a power failure or failure, the photoluminescent unit 30 emits the accumulated light to identify the advertisement contents represented by the grooves 11 on the back of the cover panel 10. do. In addition, the photoluminescent unit 30 may increase the luminance of the signboard by exerting the amplified illumination of the irradiated light even when there is the light emitting member 50 or natural light.

3 is a cross-sectional view showing a photoluminescent sign according to another embodiment of the present invention. In FIG. 3, the same reference numerals as in the previous drawings indicate the same members having the same functions, and the detailed description thereof will be omitted. Hereinafter, differences from the above-described embodiment will be mainly described.

Referring to FIG. 3, in the photoluminescent signboard according to the present exemplary embodiment, the light guide plate 40 is not disposed in contact with the rear surface of the transparent substrate 10, but the light guide plate 40 is disposed, and at least the light guide plate 40 is disposed. The light emitting member is installed on one side. In addition, the photoluminescent part 30 is disposed on the rear surface of the light guide plate 40.

The photoluminescent signage having such a configuration is displayed after all of the emitted light passes through the light guide plate 40 when the photoluminescent part 30 emits the light accumulated from the light emitting member 50 and the natural light toward the display panel 10. Since it is identified on the panel 10, it can emit light more evenly.

4 and 5 are cross-sectional views showing a photoluminescent sign according to another embodiment of the present invention. 4 and 5, the same reference numerals as in the previous drawings indicate the same members having the same function, and detailed description thereof will be omitted.

First, referring to FIG. 4, in the photoluminescent signboard according to the present exemplary embodiment, the photoluminescent layer 31 is applied to the groove 11 etched in the display panel 10 instead of the paint layer 20. In addition, the light guide plate 40 is disposed on the rear surface of the display panel 10, and the light emitting member 50 is disposed around the light guide plate 40.

Herein, the constituent material of the photoluminescent layer 31 may be configured in the same manner as the photoluminescent unit 30. In addition, alternatively, a predetermined pigment may be mixed with the photoluminescent material to express a desired color such as red, yellow, green, blue, and the like, thereby ensuring more decorativeness and discrimination.

Preferably, the photoluminescent sign may further include a protective coating layer 61 coated on the photoluminescent layer 31. The protective coating layer 61 protects the photoluminescent layer 31 from the outside to maintain durability.

Subsequently, referring to FIG. 5, in the photoluminescent signboard according to the present exemplary embodiment, an opaque portion 70 is disposed on a rear surface of the display panel 10, and a light guide plate 40 is disposed on a rear surface of the opaque portion 70. In addition, a light emitting member 50 is installed around the light guide plate 40.

The opaque portion 70 prevents light incident on the hole 11 through the light guide plate 40 from being excessively bright, which makes it difficult to identify the signboard content. That is, the light passing through the light guide plate 40 is further weakened so that visually softer light is displayed on the signboard.

The photoluminescent sign having the configuration as shown in FIG. 4 or 5 is emitted from the light emitting member 50 and is incident to the hole 11 through the light guide plate 40. Then, the photoluminescent layer 31 accumulates the light incident on the hole 11. Then, when the use of the light emitting member 50 is impossible, the photoluminescent layer 31 emits the accumulated light, whereby the portion of the hole 11 representing the signboard content emits light. Therefore, it is possible to ensure the identification of the sign without the light emitting member 50 at night. In addition, the photoluminescent layer 31 may increase the luminance of the signboard by exerting the amplified illumination of the irradiated light even when there is the light emitting member 50 or natural light. In particular, in the present embodiment, the photoluminescent layer 31 which is weak to external stress is disposed inside the signboard, so that the reliability of the photoluminescent layer 31 can be more stably ensured.

Meanwhile, in the luminous signage according to the present invention, the content of the signage may be commercial content, but is not limited thereto, and may be used as various signages such as emergency exits and traffic signs.

As described above, although the present invention has been described by way of limited embodiments and drawings, the present invention is not limited thereto and is intended by those skilled in the art to which the present invention pertains. Of course, various modifications and variations are possible within the scope of equivalents of the claims to be described.

As described above, the luminous signage according to the present invention can sufficiently secure the discriminating power of the signage even in a state in which there is no light emitting source due to a failure or power failure of the lighting fixture.

In addition, when a light emitting source is present, the signboard can be represented with high brightness without using a light emitting source having a large power consumption.

In addition, the photoluminescent material may be protected from external stress to maintain its performance to ensure more reliable sign of the photoluminescent sign.
