Abstract
Description
The present invention relates to a lighting sign, and more particularly, to a lighting sign that enables slimming and simplified structure of a product while improving luminous efficiency by optimizing an installation position of a light source on a light guide plate.
Various signs are used on the road to indicate the state of the road and the direction of travel. Most of the signs used in the meantime were made without a separate lighting, so it was very difficult for drivers to identify signs, especially at night.
To solve this situation, signs and letters were made using luminous material on signs. However, in the case of luminous, there was a problem of relatively low discrimination.
Recently, a variety of light sources are installed inside the signs to emit light from the signs themselves, so that drivers are informed of the state of the road and the direction of travel.
However, since the light sources inside the signboard are generally installed around the edge of the light guide plate, there is a problem of increasing the size of the sign as a whole, and there is a problem in that the light from the light source cannot be used effectively.
Accordingly, an object of the present invention is to solve the conventional problems as described above, and to provide an illumination sign plate which emits light by placing a miniaturized light source inside the sign, in particular, the light guide plate.
Another object of the present invention is to provide a lighting sign plate that minimizes the size and overall size of the configuration for electrical connection to the outside by minimizing the size of the light source.
Another object of the present invention is to vary the amount of light from the light source according to the position of the sign to use the light efficiently.
According to a feature of the present invention for achieving the object as described above, the present invention is a case, a front plate coupled to the case and formed with an indicator, a light guide plate installed in the front plate and the case, and An illumination cover plate including a light source for emitting light to the front plate through the light guide plate, wherein the installation slit is formed long in one direction at a position corresponding to the region where the display symbol is formed in the middle portion of the width direction of the light guide plate, The light emitting device that emits light and receives the light source is installed on the substrate.
The installation slit is formed in the form of a through hole or a groove.
The light guide plate has a refractive portion formed in an area outside the area corresponding to the display symbol.
The refraction portion is small in the area close to the light source, large in the area far from the light source, and densely arranged in the area larger than the area in which the refraction part is relatively small.
The reflective part is provided between the light guide plate and the back plate of the case.
The light emitting device is densely arranged in a wide area where the refraction is formed, and is relatively wide in a narrow area where the refraction is formed.
The light source is connected to the solar cell unit to receive power.
A double-sided light emitting device of the substrate is provided.
In the lighting sign according to the present invention can obtain the following effects.
First, in the lighting sign plate of the present invention, a groove or a hole is formed in the light guide plate, a light source is installed in the light guide plate, and light is transmitted to the edge of the light guide plate, thereby reducing the overall size and thickness of the lighting sign plate.
In addition, in the present invention, the light source is formed by installing a light emitting device on one double-sided board or a single-sided board integrated with each other. It also has the effect of being simplified.
In the present invention, since the light emitting device mounted on the substrate constituting the light source is different in the installation interval and the size and the interval of the refraction portion according to the display content, it is possible to use the light more effectively, so that the light can be economically used. It also works.
In addition, in the present invention, since the light is transmitted in the front direction of the lighting signboard in the region excluding the display content by the refraction portion formed in the light guide plate, visibility at the front and the side of the lighting signboard is simultaneously secured, and the identification at a long distance is also improved. .

Figure 2 is an exploded perspective view showing the configuration of an embodiment of the present invention.
Figure 3 is a perspective view showing the configuration between the light source and the light guide plate constituting an embodiment of the present invention.
Figure 4 is an enlarged detail showing the characteristics of the refractive portion formed in the light guide plate of the embodiment of the present invention.
Figure 5 is a use state showing a state in which the embodiment of the present invention is used.
Hereinafter, the configuration of a preferred embodiment of the lighting sign according to the present invention will be described in detail with reference to the accompanying drawings.
As shown in the drawings, the case 10 forms the back and side surfaces of the lighting sign. In the present embodiment, the side wall 14 is orthogonally connected to protrude from the edge of the rectangular rear plate 12 in the present embodiment. A predetermined inner space 15 is formed inside the case 10 by the back plate 12 and the side wall 14. The case 10 may be made of a synthetic resin material, for example, ABS resin is used.
A panel groove 16 is formed in the back plate 12 of the case 10. The panel groove 16 is recessed from the front of the back plate 12, it is formed to protrude to the back of the back plate 12. In the present embodiment, two panel grooves 16 are formed in the upper part and the lower part. However, two panel grooves 16 are not necessarily to be formed. Only one panel groove 16 may be formed or two or more may be formed, and the shape of the panel groove 16 may be various.
A reinforcement panel 16 ′ is seated in the panel groove 16. The reinforcement panel 16 ′ may be made of, for example, a metal material. The reinforcement panel 16 ′ is seated in the panel groove 16 and fastened by the fastening bolt 17. The portion where the reinforcement panel 16 ′ is positioned is a portion to which the support 50 and the case 10 to be described below are coupled.
In the center of the back plate 12 is a reinforcing channel 18 is formed in a cross shape. In the middle of the reinforcing channel 18, that is, the portion where the two reinforcing channels 18 intersect, a wire through 18 'is drilled. The portion where the reinforcing channel 18 intersects has a circular shape, and the wire through hole 18 'is drilled in the center thereof. Thus, the reinforcing channel 18 is provided to reinforce the strength of the case 10 by reinforcing the strength of the portion through which the wire through 18 'is drilled. Reference numeral 10 ′ is a fastening hole where a screw (not shown) for fastening the light guide plate 20 to be described below to the case 10 is fastened.
The light guide plate 20 is seated in the inner space 15 of the case 10. The light guide plate 20 is made of a transparent material to transmit light well. The light guide plate 20 may be made of acrylic resin or polycarbonate. As a property of the material, polycarbonate can be made relatively thin due to its excellent heat resistance and mechanical strength.
An installation slit 22 is formed through the light guide plate 20. In this embodiment, the installation slit 22 is formed to cross in the vertical direction at the central portion of the light guide plate 20. However, the installation slit 22 may be formed at an inner portion of the light guide plate 20 corresponding to the display symbol 42 to be described below. The installation slit 22 is not necessarily formed to penetrate the light guide plate 20, but may be in the form of a groove recessed in one surface. In the present embodiment, the installation slit 22 is formed vertically longer along the middle portion of the light guide plate 20 in the width direction, but is not necessarily required. The installation slit 22 may be in an area corresponding to the indication symbol 42 to be described below.
On one surface of the light guide plate 20, as shown in FIG. 4, the refraction portion 24 is formed. The refracting unit 24 is to refract the transmitted light to be delivered to the front of the lighting sign. The refractive portion 24 is formed on the surface opposite to the case 10 among the surfaces of the light guide plate 20. The refraction portion 24 may be formed by coating the paint in the form of dots or by processing the light guide plate 20 itself so that light may be refracted on the surface of the light guide plate 20. The refractive portion 24 is best formed using a silk printing method.
The refractions 24 vary in size or density depending on their location. 4, the closer to the installation slit 22, the smaller the size of the refracting portion 24 is and less compact. This is to allow the light emitted from the light source 30 to be described below positioned in the installation slit 22 to be refracted more far away from the portion closer to the installation slit 22 to go forward. This is to increase the amount of light emitted through the refraction part 24 so that the light is relatively smaller as the distance from the installation slit 22 increases, so that light is uniformly emitted from the entire area of the light guide plate 20. The refraction portion 24 increases in size toward the edge of the light guide plate 20 to relatively reduce light exiting from the end of the light guide plate 20 to the edge of the light guide plate 20. Reference numeral 20 'is a fastening hole.
The reflective part 26 is provided between the light guide plate 20 and the back plate 12 of the case 10. The reflector 26 may be a white synthetic resin sheet. The reflector 26 prevents light from being transferred from the light guide plate 20 to the case 10 and reflects the transmitted light to the front of the lighting sign. The reflector 26 is not necessarily required as long as the back plate 12 of the case 10 has a reflective function. The reflector 26 may be integrally formed on the rear surface of the light guide plate 20. That is, the reflective part may be formed by attaching a synthetic resin sheet to the rear surface of the light guide plate 20 or by processing the light guide plate 20 itself.
Communication slits 28 are formed in the reflector 26. The communication slit 28 has the same shape and size as the installation slit 22 of the light guide plate 20. The reflective part 26 has a fastening hole 26 'formed at a position corresponding to the fastening hole 20'.
As shown in FIGS. 3 and 4, the light source 30 includes a light emitting element 34 installed on the substrate 32. The substrate 32 is a kind of printed circuit board that is formed of a narrow width and a long length. In the present embodiment, the width of the substrate 32 is approximately equal to the thickness of the light guide plate 20, and the dimensions including the substrate 32 and the light emitting element 34 are equal to the width of the installation slit 22. The substrate 32 may be made by using a double-sided board on which the light emitting device 34 may be mounted on both sides, or by stacking two single-sided boards on which the light emitting device 34 may be mounted on only one surface.
As the light emitting element 34 mounted on both surfaces of the substrate 32, for example, an LED is used. The light emitting device 34 receives power supplied from the outside through the wire 36 to emit light. The light emitting device 34 is not provided at regular intervals on the surface of the substrate 32 in this embodiment, the interval is different depending on the position. This is because the required amount of light emitted from the light source 30 depends on the area of the region where the refraction portion 24 is formed.
Therefore, the light emitting element 34 is densely arranged in the wide area where the refraction portion 24 is formed. In the narrow area where the refraction portion 24 is formed, the light emitting elements 34 are disposed at wide intervals. This can be seen in FIG. 4. In the substrate 32 of the light source 30, the light emitting devices 34 on the right side of the drawing are arranged very densely, and the light emitting devices 34 on the opposite side are very wide. It can be seen that the arrangement is.
The front plate 40 is located at the front of the light guide plate 20. The front plate 40 has a sign 42 is formed. The symbol 42 is a so-called chevron in this embodiment. However, the shape of the indicator 42 may be various. In this case, the display symbol 42 is preferably black, and portions other than the display symbol 42 are yellow, which is complementary with black. In particular, the sign 42 is black and relatively harder for light to pass through, so that all light passes through the yellow region, which is a part other than the sign 42.
The front plate 40 is preferably the edge is bonded to the side wall 14 of the case 10. The front plate 40 is adhered to the side wall 14 to prevent water from penetrating into the case 10. In order to waterproof between the front plate 40 and the side wall 14, a separate rubber packing may be adhesively fixed. The front plate 40 is preferably made of acrylic material.
On the other hand, the lighting sign of the present invention, as shown in Figure 5, is installed on the support 50 standing on the ground. The case 10 is mounted on an upper end of the support 50. The case 10 has a rear surface of the back plate 12 corresponding to the reinforcement panel 16 ′ is fastened to the case 10 through a separate bracket (not shown).
The light source 30 receives power from the outside, for example, there is a solar cell unit 60. The solar cell unit 60 supplies power by solar energy. At this time, the charged electrical energy is used for 12 hours of daytime or 24 hours of day and night. Of course, the power may be supplied from a normal battery, or may be constantly supplied through an electric cord. The light source 30 of the present invention can emit light by a flashing method or a lighting method that continuously maintains a light emitting state.
It will be described below that the lighting sign according to the present invention having the configuration as described above is used.
The lighting sign of the present invention is to provide information on the road condition to the driver on the road. In the illustrated embodiment, the curved direction of the road is indicated by a so-called chevron so that the driver can predict the traveling direction in advance.
In particular, the lighting sign of the present invention can be better recognized by the driver 42 by the light source 30 emits light. The light emitted from the light source 30 is transmitted in all directions along the light guide plate 20, and in the part where the refraction part 24 is located, the light is refracted by the refraction part 24 and moves toward the front plate 40. .
Of the light traveling along the light guide plate 20, the light that has moved toward the reflector 26 is reflected to change the path toward the front plate 40. The refracting portion 24 formed on the light guide plate 20 is relatively small in size and is not densely arranged in the region adjacent to the light source 30. In the region far from the light source 30, the refraction portion 24 is large and relatively densely arranged so that the light is refracted toward the front plate 40.
In particular, light is uniformly transmitted to the front plate 40 in the region of the refraction portion 24 of the light guide plate 20 due to the size and density of the refraction portion 24. Therefore, light is uniformly transmitted to the outside of the front panel 40 except for the display symbol 42, so that the driver can recognize the display symbol 42 more accurately.
On the other hand, the light emitting element 34 mounted on the substrate 32 of the light source 30 is densely installed in the wide part of the region of the refraction portion 24. This is because a large amount of light must exit toward the front plate 40 in the wide portion of the refraction portion 24 region.
In the narrow portion of the region of the refracting portion 24, the light emitting element 34 is provided at a wide interval. This is because the amount of light required in the narrow portion of the region of the refractive portion 24 is large. Because it does not.
The light emitted from the light source 30 is transmitted to the front plate 40 through the light guide plate 20 in the same manner as described above. The front plate 40 is also mainly provided with a portion in which the indicator 42 is not formed. It is passed out. This is illustrated well in FIG. When the light exits to the outside of the front panel 40 through the portion where the display symbol 42 is not formed, the driver may easily recognize the display symbol 42 while emitting light to a portion except for the display symbol 42. It will be possible.
In addition, the light source 30 receives power through the solar cell unit 60. The solar cell unit 60 receives solar light, generates electricity, collects the electricity, and transfers the light to the light source 30 when necessary, so that the light emitting device 34 generates light. Such an operation is performed in a part of controlling the operation of the solar cell unit 60. When the peripheral illumination is low, that is, at night, the light emitting element 34 emits light to the solar cell unit 60. The stored power is supplied to the light emitting element 34.
The scope of the present invention is not limited to the embodiments described above, but is defined by the claims, and various changes and modifications can be made by those skilled in the art within the scope of the claims. It is self evident.
For example, although the shape of the entire lighting sign is rectangular in the illustrated embodiment, it may be made in various shapes such as circular, pentagonal, and hexagonal. To this end, the shape of the case 10, the light guide plate 20, the front plate 40, etc. may be made as such.
In addition, in the illustrated embodiment, the light source 30, the installation slit 22, and the like may be formed in a chevron like the shape of the indicator 42. In such a case, the spacing of the light emitting elements 34 of the light source 30 should be slightly different from that shown.
On the other hand, as described above, the indicator 42 may be used in addition to the illustrated embodiment.
