Description

Light illumination display board and lamp shade displayed multiple illumination with engraved surface on transparent acrylic plastic plates}

The present invention is to enable the production of characters, pictures, etc. formed in advertisements and stand lighting by various colors and motions by irradiating light in a transparent acrylic plastic plate, using the property of refraction and reflection of light (Illumination Light) Display devices, such as advertisements and lighting stands, which form various sculptures and grooves in the shape of letters and pictures, and are irradiated on transparent acrylic plastic plates attached to the back of them to display various lights and pictures (light signs) And an illumination directing device of the stand).

Conventional lighting signboards have a flat surface where the edge edges of transparent or translucent plastic plates are plated by a so-called edge lighting method, and the light source installed on the edge edges of this plane Light rays are incident from the light source, and the illuminance and contrast of the advertising surface depend only on the arrangement and the light intensity of the illumination source, and thus the desired illuminance, business cards, their modulation, and three-dimensional effects cannot be realized.

Accordingly, U. S. Patent No. 5124890, co-invented by the present applicant, is formed of a transparent acrylic plastic plate as described in the specification, and the edge of the transparent acrylic plastic plate is made by using the property of refraction or reflection of light rays in the transparent plate. A signboard in which light rays are incident on a surface, and a sign made of letters, figures, symbols, or a combination thereof is displayed on the surface. The edge is also flat.

In addition, various lamps, such as an incandescent lamp, were used as an illumination source of an advertisement surface. These lamps were placed in a narrow enclosed space in the frame of the billboard so that they could be hot due to the heat generated by these lamps, and the amount of heat generated by using a lot of high-power lamps to increase the illuminance of the advertisement surface and to obtain the contrast effect. The color sheet attached to the entrance surface of the acrylic plastic plate and the acrylic plastic plate becomes larger and more thermally discolored or distorted, and the light rays irradiated to the surface when used for a long time. This results in color modulation and lowering of illuminance and significantly lowers advertising or lighting functionality.

Lighting lamps for electric stands used indoors or on a table are made from natural or chemical fibers with a transparent cloth or sheet material, etc. Conical or cylindrical ones have been conventionally used to block direct sunlight to obtain an indirect lighting effect.

However, these lampshades have been mainly used for the simple lighting function of the stand, and in some cases, drawings, characters, colors, shapes, or a combination thereof were drawn or printed on the surface of the lampshade.

As described above, a lighting signboard made of a conventional acrylic plastic plate is incident on light rays depending only on a flat edge surface, and in particular, it is not possible to obtain changes in illuminance, contrast, and color desired during the day, There is a drawback that heat discoloration, distortion, and deformation due to heat are present, so that the display of advertisements and the like is clear, and an advertisement lighting apparatus that can be used for a long time has been desired.

The present invention solves the above problems, it is possible to obtain the modulation of illuminance, contrast, three-dimensional shape and color as desired, laminating a transparent acrylic plastic plate without decay of the lighting effect over time. The purpose of the present invention is to provide a lighting signboard and a lampshade of the lamp stand, which can clearly display the image to be displayed on the surface or the surface and the back of the billboard, and in the case of the lamp stand.

In the present invention, by varying the sculpting method, such as line expression sculpture, plane sculpture, scratch sculpture, etc., the pastel effect can be obtained, various three-dimensional feelings can be expressed, and in particular, the effect of being sucked into the interior (Cubic Effect) can be exhibited. .

Referring to the embodiment of the present invention configured as described in detail as follows.

1 is a front view of a lighting signboard according to the present invention, FIG. 2 is a partial perspective view of a part of the lighting signboard of the present invention, and generally, the lighting signboard is composed of three overlapping transparent acrylic plastic plates (2), (3), ( 4) and a plurality of lighting bulbs 6 provided with lamp partitions 18 so as to allow light rays to be incident on the edges of the respective transparent acrylic plastic plates 2, 3, and 4 as incident surfaces; The PCL 11 or the like for controlling the operation of the lighting bulb 6 is structured to be closely adhered to by the signboard frame 1 and the signboard back plate 8.

In the present invention, each of the transparent acrylic plastic plates (2), (3), (4) without packing directly overlapping, as shown in Figure 3 packing 14 having a thickness of about 0.5mm on the four edge edge surface portion And lamp partition 18 are placed in close contact with each other. The packing 14 can prevent blister film formation between the plate and the plate due to moisture contained in each of the transparent acrylic plastic plates 2, 3, and 4 itself, and between the plates. As will be described in detail below by the space formed in the above, it is possible to reinforce the three-dimensional expression which is very important for the expression of advertisement by diversifying the laminated structure and the engraving method of the transparent plate.

In addition, by installing a lamp partition 18 between each of the transparent acrylic plastic plates (2), (3), (4) to control the lamps of four edges with the PCL (11), each transparent acrylic plastic plate (2), (3), (4) The carved characters and the color of the picture are changed to completely different colors, so that the animation effect can be expressed at the same time, and the color and color light are mixed inside each transparent plate. Various colors can be displayed than the expression medium.

On the front or rear of the transparent acrylic plastic plate (2), (3), (4) to form a piece corresponding to the characters and pictures to be displayed on the display surface (5), which is the front of the lighting sign, respectively, A color reflecting plate 7 is attached between the transparent acrylic plastic plate 4 and the signboard back plate 8.

The color reflector 7 attached to the rear surface of the transparent acrylic plastic plate 4 serves to reflect the light emitted to the back of the lighting signage in the front direction and to form a three-dimensional effect, which is a signage back plate 8 ) Is firmly supported.

In addition, four edge surfaces of each of the transparent acrylic plastic plates 2, 3, and 4 corresponding to the lighting bulb 6 are precisely processed to form detailed divided surfaces of various shapes such as 2c, 3c, and 4c. Process to have.

The shape of the four sides of these transparent acrylic plastic plates (2), (3) and (4) is mainly used to have two to three detailed divided surfaces, as shown in Figure 3, 4 sides or as It may be processed to have a detailed divided surface of the five sides, such as, but is not limited thereto.

As described above, unlike the conventional lighting sign that used the shape of the side surface of the acrylic plastic plate as it is, it is configured to have a subdivided surface having a plurality of various angles, which is a key feature of the present invention. In addition, by passing the light beams through the subdivided planes having different angles, the light paths can be diversified to obtain a variety of color representations not solved by the prior art.

The subdivided surfaces 2c, 3c, and 4c formed by precision machining on a CNC lathe, etc., are suitable for realizing characters and pictures and colors as desired and modulating a combination thereof as reflections and refractions of light rays on a lighting signboard. Cut and attach a translucent color sheet (13; color sheet) of various colors so as to cut.

The color band of the color sheet 13 is composed of a combination of thin lines having various colors, brightness, and hue, and lines having a fairly wide width. The signboard is designed according to the program suitable for letters, pictures and their color combinations.

In addition, when a stronger screen illumination is required, as shown in the plastic light transmission diagram of FIG. 4, if the LOGO to be expressed, which is a disadvantage of the planar transparent acrylic plastic, is complicated, the engraving area is increased so that the center part of the LOGO to be expressed ( Transparency Center) There is a big disadvantage that the illuminance is different on the screen due to insufficient reflection of light. This is because the irradiated light almost reflects in the groove of the outer portion of the transparent plate, the irradiation amount of light is insufficiently reflected in the central portion of the transparent plate, the difference in illuminance occurs in the outer and center of LOGO.

Accordingly, in order to overcome this problem, when the transparent acrylic plastic plate is manufactured in a concave lens shape as shown in FIG. 6 and carved into the curved surface, the length of the engraving groove is adjusted by the transparent thickness, and the length of the carving groove is moved to the center of the transparent plate. Deepens. When the illumination bulb 6 is irradiated to the side divided into two, three, and four transparent plates, all the light is not reflected to the slit grooves on the outer side of the transparent plate, and more than half of the dose is reflected and refracted to the center portion of the plate. Since the entire illuminance is uniform, the illuminance of the screen can be strengthened by eliminating the illuminance difference caused by the uniform thickness.

Thus, FIG. 4 illustrates a profile of three subdivided surfaces in the groove 2c of the plastic plate. For example, each of the three edges 2c-1 of the transparent acrylic plastic plate 2 shown in FIG. 4 is attached with a green light system, a vermilion light system to 2c-2, and a purple light transmitting color sheet to 2c-3. Will be done. That is, the light rays incident through the colored light rays passing through the color layers 2c-1, 2c-2, and 2c-3 of the subdivided surfaces forming a plurality of different angles are pieces carved on the surface of the acrylic plastic plate. Reflected or refracted at the surface, the logo arranged on the display surface 5 of the illuminated display board combines color and color light to provide many colors.

On the other hand, a glass heat sink 9 is inserted in the space between the lighting bulb 6 and these subdivided surfaces 2c, 3c, and 4c, and each heat sink 9 has a small vent for ventilation. The heat dissipation hole 10 is formed long. The heat radiating element 9 and the heat radiating hole 10 inserted between the lighting bulb 6 and the subdivided surfaces 2c, 3c, and 4c have a side of the transparent plate in which heat is emitted from the lighting bulb 6. It prevents the direct reflection on the subdivided surface of the, and promotes the heat dissipation and divergence of the bulb, thereby eliminating the conventional problem caused by the heating of the illumination source.

In this way, the light beam irradiated from the lighting bulb 6 passes through the respective color sheets 13 attached to the respective subdivided surfaces 2c, 3c, and 4c, and thus each transparent acrylic plastic plate. (2), (3), (4), each piece (2a), (3a), (3b), (4a), (4b) and V-shaped outline pieces (16), flat scratch pieces ( It is reflected and refracted at the engraving site of 17) to express the signboard sign (character, picture {shape plate 15} and combination thereof) as designed on the display surface 5 of the illuminated signboard.

At this time, the image of any color or light character or picture is not projected onto the display surface 5 from the part of the transparent plate other than the carved part, thereby providing a uniform background light without any difference in brightness or color. Only the planned mark is clearly expressed.

In addition, the pieces carved into these transparent acrylic plastic plates 2, 3, and 4 are as shown in FIG. 3, in the case of the transparent acrylic plastic plate 2 serving as the surface 5, the surface 5 Piece (2a) is carved only on the opposite side of), and for other transparent acrylic plastic plates (3) and (4), pieces (3a), (3b), (4a) and (4b) both on the front and back of the plate. This can be carved.

In the case of the transparent acrylic plastic plate 2, the surface of the display surface 5 can be sculpted. However, if dirt or dust is caught in the engraving area, the function of the billboard can not be properly exhibited. Attach or insert protaction cover 19 of transparent plastic plates or colored acrylic plastics or colored glass whose surface is reinforced by special processing.

The present invention, which is implemented as described above, is not limited to the lighting signboard, but is a desktop type photo frame combined lighting stand that uses various lights indicating color production, animation and the like and an illuminated display attached to the floor of a building interior. It becomes a display board and can be mounted as a brick of side walk display board in a brick of side walk.

Accordingly, the present invention will be briefly described above. That is, the desktop photo frame lighting stand inserts a colored plastic protector plate (19) and widens a scratch on the plate (17) on the back of the transparent acrylic plastic plates (2) and (3) on a photo size scale. When the photographic film or the printed photograph is brought into close contact with the front part of the transparent acrylic plastic plate 2 and irradiated with the lighting bulb 6, the film contents are displayed and the indoor lighting effect is also given. The protection board 19 is mounted on an illuminated display board to balance the existing floors or newly installed floors of various buildings, and cut and install part or all of the floors. The room's lighting effect can be achieved while the required representations (characters, pictures) are displayed without being damaged. In this way, you can use it as a new concept as an outdoor brick brick side board.

In addition, the color sheet on the front or back of the transparent acrylic plastic plate (2), (3), (4) in order to reinforce the vivid color when used in daytime, in addition to engraving directly on the front or rear of the transparent plate in this way The shape color plate 15 cut to a desired shape and color of the film or the like may also be directly bonded, and a detailed method thereof will be described later.

As one embodiment, in the case of expressing 'KOREA SEOUL' as shown in Figure 1 on the illuminated signboard consisting of three transparent plates of Figure 2 may be carved as follows.

The KOR (2a) of KOREA is carved on the upper end of the transparent acrylic plastic plate (2), and the transparent acrylic plastic plate (3) is aligned side by side with the KOR (2a) of the transparent acrylic plastic plate (2) so that the EA of the KOREA character 3a), and then engrave SEO (4a) among the SEOUL letters on the front lower part of the transparent acrylic plastic plate (4), and align them in parallel with the front SEO (4a) letters on the rear lower part of the same transparent acrylic plastic plate (4). In order to sculpt UL 4b, 'KOREA SEOUL' is expressed on the surface 5 by using the refraction and reflection of light.

The color program to be expressed in the texts and pictures engraved in this way and formed on the subdivided surfaces 2c, 3c, and 4c, which are precisely formed on the transparent acrylic plastic plates 2, 3, and 4, respectively. By precisely cutting and adhering the color sheet 13 by means of irradiating the light of the lighting bulb 6, the characters and drawings engraved on the transparent acrylic plastic plates 2, 3, and 4 are required. As expressed in color, a specific example of the color usage method is described as follows.

The green, purple and purple color plates are cut and adhered to the three precision machined detailed side surfaces of the detailed divided surface 2c of the transparent acrylic plastic plate 2, and the detailed divided surface of the transparent acrylic plastic plate 3 Both details of 3c) are glued with a red color plate, and the two details of the subdivided surface 4c of the transparent acrylic plastic plate 4 are divided into left and right sides on the side corresponding to the engraving part of SEO 4a. When the yellow sheet is bonded, and the blue sheet is attached to the side corresponding to the lower back UL (4b) letter piece, and the lighting bulb 6 is turned on, the green or scarlet color is applied to the KOR (2a) of the transparent acrylic plastic plate (2). , Purple is expressed in three colors up, down, left and right, and red is displayed on the EA 3a of the transparent acrylic plastic plate 3. Therefore, the upper KOREA character of FIG. 1 is represented by four colors of green, scarlet, purple, and red.

The letters SEOUL of the transparent acrylic plastic plate 4 are also expressed in a mixture of yellow and blue in the front letter SEO (4a) and the rear letter UL (4b), so that the letters 'KOREA SEOUL' of FIG. 1 are colored in vivid colors of six colors. It can be.

As such, a method of carving letters or symbols on the transparent plate is generally a method of carving the same pieces on a plurality of overlapping transparent plates, and when overlapping them, the pieces are completely matched.

However, as shown in Fig. 3 and Fig. 5 (extracting the transparent acrylic plastic plate polymerized during the cross-sectional view of Figure 5, supplemented with a separate perspective view), the back of the transparent acrylic plastic plate 2, such as a letter or symbol to be expressed Carved into the V-shaped outline piece (16), and the back of the transparent acrylic plastic plate (3) overlapping the scratches to scratch the surface of the outline as scratched, and the same shape as the scratch piece (17) of the transparent plate Or the shape color plate 15 which cut out the film is adhere | attached on the whole surface. In addition, when a higher illuminance is required, another shape plate 15 cut in the same shape as the shape plate 15 is bonded to the rear surface of the transparent acrylic plastic plate 4.

Thus, the V-shaped outline (border) piece 16 of the transparent acrylic plastic plate 2, the scratch piece 17 and the shape color plate 15 of the transparent acrylic plastic plate 3, and the transparent acrylic plastic plate 4 When overlapping the shape plate 15 of the shape so as to completely merge, the surface to be exposed not only at night, but also during the day, the illumination is improved as the shape plate, and the object to be expressed more clearly and three-dimensionally The effect is as if it is being sucked deep inside (Qubic Effect).

As a result, various color expressions and color modulations, screen brightness enhancement and contrast control, and three-dimensional appearance can be displayed. It is possible to increase the effect of extending the life due to use.

In addition, various color sheets 13 attached to the subdivided surfaces 2c, 3c, and 4c of each of the transparent acrylic plastic plates 2, 3, and 4 for more various color schemes and expressions. By the installation of the lamp partition 18 of the lighting bulb 6 is controlled by the PCL 11, the lighting sequence and the illumination intensity is expressed in various colors.

In other words, each of the transparent acrylic plastic plates 2, 3, 4, the detailed divided surfaces 2c, 3c, 4c have different colors, for example, red, blue, orange, Each transparent acrylic plastic plate is attached by attaching a color sheet 13 of four yellow colors and controlling the illumination bulb 6 for injecting light rays into the respective color sheets 13 by the PCL 11. The shape represented by the combination of the sculptures engraved in (2), (3) and (4) can be expressed in a single color such as red or blue, and the color can be modulated into another color and mixed colors of various colors. On the other hand, it is also possible to change the animation expression and the color that is periodically expressed to move the expression picture of (a), (b), (c) of FIG.

The animation lighting production of the present invention is the four of the transparent plate by the fade-in (fade-out) effect of the amount of light by the overlap of the on-off function of the light bulbs 6 by the PCL (11) The color light divided by the subdivision plane of the edge is instantly modulated to a completely different color, and at the same time, the animation is expressed in a fantastic color by the animation expression and their composite effect. That is, the operation figure of the animal is formed in the above-described configuration, the transparent acrylic plastic plates (2), (3) (4) and then formed on the detailed divided surface of the four edges of the four edges of the transparent plate in Figure 7 (a), If you change the lighting of completely different color in the order of (b), the person who sees the lighting sign can make the moving image of the animal move continuously as in (c). The present invention can be used in any existing commercial signage, interior, corporate and brand integrated image, promotional advertising and various stand lighting, it is possible to more efficiently produce the color of the advertising expression and lighting.

The transparent acrylic plastic plate uses a property that light is refracted and reflected only on a flat plate, as in the case of an electric lighting signboard, but not on a curved plate, but also on a curved plate. It can be used as a lampshade for a floor lamp. By using the lampshade of such a lamp, it is possible to enhance the effect of interior decoration and to express emotional works and educational utility by expressing artistic works, mottos, famous sayings, and acts, including beautiful landscape paintings. In addition, it may be an electric stand capable of effectively expressing characters, drawings, shapes, colors, and combinations thereof so as to exhibit an effective advertising effect in commercial use.

Therefore, an embodiment of the floor lamp using the configuration of the lighting signboard of the present invention will be described. The lampshade stand is a support frame for supporting the annular lamp 22 and the lampshade 23 on the top of the stand body 21 as shown in FIGS. 8, 9, 10, 11, and 12a, 12b, 12c. There is 24. The support base 24 is composed of several support pieces 25 fixed to the upper part of the stand body and an annular lampshade support member 26 fixed to the upper end of the support piece 25.

And the elastic piece 27 which supports the annular lamp 22 is provided in the middle part of these support pieces 25, and the annular part is provided below the electric annular lamp 22 in the middle part of each support piece 25. The reflecting mirror 28 is attached by the attachment piece 29.

The lampshade 23 forms a conical annular portion by closely overlapping a plurality of relatively thin transparent acrylic plastic plates, and inverts the conical shape by bending inward from the upper portion thereof. The annular portion of the shape is formed integrally.

The cross section is as shown to FIG. 10, FIG. However, the outer annular portion of the lampshade may be conical or cylindrical, not necessarily conical, but the inner reverse conical annular portion may have a cylindrical shape, which may reduce lighting efficiency.

Fig. 10 shows lampshades formed of two transparent acrylic plastic plates 30 and 31, wherein the edges 30b and 31b, which are the lower ends of the inner annular portion of the reverse cone shape, are taken from the annular lamp 22. It is an incident surface of light.

That is, the groove 30b precision-processed is formed in the plate 30 which forms the short edge surface which is the lower end of the annular conical part of the inner side, and the groove 31b is carved in the other plate 31, and it is opposed to this. The 22 is aligned to be aligned with the center of the reflector 28 so that the light beam is projected to the grooves 30b and 31b of the leading edge as much as possible.

On the surfaces of the two plastic plates 30 and 31 constituting the lampshade, pieces 30a and 31a such as letters, symbols, figures or paintings are shown in FIGS. 10 and 11. A transparent or translucent sheet is attached to the inner surface of the outer cone shape.

As shown in FIG. 10, grooves 30b and 31b having two to three flat three-sided surfaces having different angles are formed by precision machining on the inverse conical surface of the inner side of the lampshade. The three sides of the color sheet is attached.

These grooves are incident surfaces of the light beams from the illumination lamps, which are reflected or refracted by the plastic plate so that letters, symbols, figures, etc. carved on the surface of the plate are displayed on the surface of the lampshade.

At this time, from the acrylic plastic cone shaped lampshade parts other than the carved parts of the plastic plates 30 and 31, no image of color or light characters or pictures is projected onto the lampshade, so there is no difference in brightness or color. It provides a uniform background light, and only the planned mark is clearly displayed on the lampshade surface, which is based on the same principle as in the case of the electric light signboard.

In addition, the transparent or semi-transparent sheet 33 attached to the back of the outer cone-shaped lampshade functions to partially block the transmission of the light beam from the illumination light source and to reflect back the light incident into the lampshade plastic plate. This sheet also serves to control the backlight of the entire lampshade and to prevent the lampshade from being stigmatized.

And as shown in Figure 8 as an example, if you want to express the letter 'I LOVE YOU' on the outer surface of the lampshade 'I' letter (30a) and the 'I' letter at the upper right side of the back of the plastic plate 30 The 'YOU' character (30a) is carved, and the cone plate 31 is aligned with the 'I' character (30a) to engrave the 'LOVE' character (31a). When the lighting fluorescence is turned on, 'I LOVE YOU' is displayed on the outside of the lampshade.

In this case as well, each of the three surfaces formed in the grooves 30b and 31b of the end surface of the annular cone of the inverted cone shape inside the lampshade is precisely cut and bonded with a color sheet of various colors to 'I LOVE YOU'. To express the color required for

As a specific example of the method of using such a color sheet as shown in Fig. 10, two sheets of green sheets are formed on two surfaces of the grooves 30b of the edge of the lampshade. A red sheet is attached to both sides, and a yellow sheet is attached to the remaining three sides, and the lighting lamp 22 is turned on, and green is displayed on 'I' and 'YOU' on the conformal outer surface, and 'LOVE'. 'Is expressed in red at the top and yellow at the bottom, and another subtle color is expressed in the center. In addition, the illumination source is not limited to the circular fluorescent tube 22a as shown in FIG. 12 (a), but is a long incandescent lamp 22b or (c) as shown in (b). As such, an incandescent ring having a small incandescent bulb 22c connected in a circular shape can be used as an illumination source.

When the incandescent lamps 22b and 22c are used, P.C.L may be used to display the colors in various colors as the sequential lighting of the lamp and the illumination intensity control.

According to the present invention, the four sides of the transparent plate can be processed into shapes having two to five subdivided surfaces, and thus not only the letters and pictures can be carved on the front and back sides of the plastic plate, but also the detailed divisions thereof. By the method of attaching the color plate attached to the surface, it is possible to express various and vivid color configurations of the surface to be displayed.

In addition, the heat dissipation insert may promote the dissipation of heat from the light bulb, thereby preventing distortion and damage to the lighting signboard and extending its life.

In addition, in the present invention, not only the V-shaped pieces on the front or the back of the transparent plate, but also the pieces of scratches, and by directly attaching the shape plate of the same shape on the corresponding surface, it is possible to realize a more clear and three-dimensional display state.
