Description

Optical fiber sign {OPTICAL FIBER SIGN}

The present invention relates to an optical fiber sign, and more particularly, to an optical fiber sign that is installed in a place or facility where there is a high risk of a danger or an accident, and informs it.

Safety signs are made into signs using symbols, pictures, and letters that anyone can easily recognize to inform dangerous places, substances, and surrounding matters.

Safety signs are attached or installed in places, facilities, ships, vehicles, etc. where there is a high risk of an accident. Safety signs vary depending on the application used, such as traffic signs, school safety signs, and industrial safety signs.

Traffic signs refer to signs designed to communicate smoothly and prevent accidents using a consistent and unified way when using the road. Traffic signs may be installed alone, or may be organically or complementarily combined with road markings and signals.

In this regard, Korean Patent Publication No. 1009603 (hereinafter referred to as'priority document 1') discloses a light-emitting type sign.

The light-emitting sign in Prior Document 1 includes a solar cell, a light source that converts electrical energy generated from the solar cell into light energy, and a display panel in which light energy provided from the light source in connection with the light source is displayed in various forms of letters or symbols. And a driving circuit connected between the unit and the solar cell and the light source unit to drive the light source unit with electrical energy generated from the solar cell.

Traffic safety signs are classified into caution signs, regulatory signs, instruction signs, auxiliary signs, and road signs.

Among them, auxiliary signs are signs that supplement the main function of caution signs, regulatory signs, or indication signs to inform road users. Examples that are often used on the auxiliary cover are as follows. In other words, there are frequent accident points, detours, emergency calls, foggy areas, icing caution, heavy snow caution, and so on.

However, supplementary signs such as icingism and heavy snowism are only valid in winter and are not suitable for other seasons. Therefore, in case of supplementary signs such as freezing caution and heavy snow caution, it is necessary to replace them with other supplementary signs in seasons other than winter.

However, the luminescent sign of Prior Document 1 has a problem that the replacement cost of the auxiliary sign occurs every year. In addition, the luminescent sign of Prior Document 1 takes a certain amount of time to replace the auxiliary sign. Therefore, there is a problem that it is not possible to respond immediately to a sudden occurrence of freezing or heavy snow.

As traffic accidents at night are the highest among traffic accidents, driving at night requires special attention. In particular, freezing can occur suddenly at night when the temperature drops. Today, due to the mass spread of automobiles, the number of automobile accidents has increased rapidly, and accidents are reported every day, and it is a big social problem. Therefore, there is a need for a method that cannot immediately respond to sudden ice formation or heavy snowfall.

In addition, the luminous sign of Prior Document 1 has a problem in that it is impossible to turn on and operate the luminous sign until the luminous sign is repaired or replaced when a solar cell is broken, a charging part is discharged, and a failure occurs. Delay in repair or replacement of light-emitting signs means the occurrence and loss of traffic accidents due to non-operation of the signs.

It is virtually impossible to check the exact installation location for light-emitting signs due to the nature of products installed on the road. In addition, there is a problem that non-operational signs and malfunctions cannot be confirmed during the daytime due to the characteristic of operating at night.

As described above, the delay in repair or replacement of the luminous sign means the occurrence and loss of traffic accidents due to non-operation of the sign. Therefore, urgent improvement of the above-described problems is required.

In addition, Korean Patent Publication No. 1992324 (hereinafter referred to as'Prior Document 2') discloses an optical fiber holder for a light-emitting type sign that improves the reliability of fixing an optical fiber.

The optical fiber holder for a light-emitting type sign of Prior Document 2 includes a body, a locking part, a grip guide, and a grip extension guide.

The body is inserted into the mounting hole formed in the panel, and an insertion hole is formed in the center to allow the optical fiber to be inserted with a gap along the length direction, and an insertion guide whose diameter decreases toward the end is provided to guide the insertion into the mounting hole. Is formed.

The locking portion is formed to be caught around the mounting hole due to an increase in diameter at the other end of the body.

The grip guide is formed to protrude from the outer circumferential surface of the body, and is elastically deformed by being pressed against the inner circumferential surface of the mounting hole when mounted. Accordingly, the grip protrusion for pressing the circumference of the optical fiber is guided to protrude from the inner surface of the insertion hole.

The grip extension guide is formed in a groove shape along the inner circumferential surface of the insertion hole. Therefore, when the grip guide is elastically deformed by compression, the grip protrusion is guided so that it is divided and expanded to both sides.

The optical fiber holder for light-emitting signs of Prior Document 2 provides a structure that guides the optical fiber to stably grip when mounted in the mounting hole of the panel, thereby increasing the reliability of fixing the optical fiber, and when mounting it in the mounting hole of the panel. There is an advantage of being able to suppress separation by the elastic restoring force.

The optical fiber is inserted into an insertion hole formed in the center of the optical fiber holder. However, the optical fiber holder for a light emitting sign of Prior Document 2 is made of a material capable of elastic deformation such as rubber, silicone, or synthetic resin having elasticity to perform gripping by elastic deformation.

The light of the optical fiber is difficult to pass through the optical fiber holder made of rubber or silicon. Therefore, the optical fiber intensively emit light corresponding to the safety sign only to the front of the panel. As a result, there is a problem that the light of the optical fiber is rapidly weakened in a direction obliquely to the front of the light-emitting type sign.

As shown in FIG. 1, a sign sheet 121 corresponding to a traffic safety sign may be attached to the front panel 120. Traffic safety signs are signs designed to enable road users to communicate smoothly in a consistent and unified manner for traffic safety.

Traffic safety signs include caution signs, regulatory signs, instruction signs, auxiliary signs, and road signs. Among them, auxiliary signs are signs that supplement the main function of caution signs, regulatory signs, or indication signs to inform road users. Examples that are often used on the auxiliary cover are as follows. In other words, there are frequent accident points, detours, emergency calls, foggy areas, icing caution, heavy snow caution, and so on. 5 shows that the cover sheet 121 displays a “slip caution” mark.

At night, when the sun goes down, the legibility of the sign decreases. A plurality of through holes 120H are formed in the front panel 120. The through holes 120H form a path through which light from the light source 400 is exposed to the outside. The through hole 120H forms a cylindrical shape. Light emitted from the through-holes 120H can increase the readability of the sign at night.

As shown in FIGS. 1 and 2, the main power unit 200 supplies power to the light source 400 and is installed in the case 100.

As shown in FIG. 3, the main power unit 200 includes a main solar cell 210, a main battery 220, and a main control unit 230.

The main solar cell 210 is provided as a solar cell that generates electricity by converting light energy from the sun into electrical energy. For example, the main solar cell 210 may be provided with a solar cell that generates 20W of power energy. The main solar cell 210 is coupled to the case 100 by a post 210P.

The main battery 220 is provided as a secondary battery to charge the electricity produced by the main solar cell 210.

As shown in FIG. 4, the light source 400 is configured to emit light by power of the main battery 220, and is provided as an LED module. Unexplained W denotes a wire connecting the light source 400 to the main control unit 230.

2 and 3, the optical fiber 500 is a configuration that transmits light from the light source 400 to the outside of the case 100 through the through holes 120H, and is provided in plural. The optical fiber 500 transmits light from the light source 400 to the outside of the case 100 without loss of light through total reflection.

One of the optical fibers 500 is disposed in front of the light source 400 by the bundle member 410. As disclosed in Korean Patent Publication No. 1992324, the light source 400 and the bundle member 410 are well-known technologies, and thus detailed descriptions thereof will be omitted.

As shown in FIG. 3, the holder 600 is configured to position the other side of the optical fiber 500 inside the through hole 120H, and is made of a polycarbonate material. Polycarbonate is a type of thermoplastic plastic, and has features such as impact resistance, heat resistance, weather resistance, self-extinguishing property, and transparency.

Polycarbonate has about 150 times more impact than tempered glass, has excellent flexibility and workability, is light, and does not scratch the surface well.

5 shows that the holders 600 are arranged in the form of a'freeze caution' sign. Some of the through holes 120H may be formed in a portion of the front panel 120 to which the cover sheet 121 is attached.

As shown in FIG. 4, the main control unit 230 may receive a measured value of the temperature sensor 1000. The temperature sensor 1000 measures the temperature of the outside air. As shown in FIG. 2, the temperature sensor 1000 may be installed on the case 100 or the post 310P.

As shown in FIG. 5(b), when the measured value of the temperature sensor 1000 becomes less than the reference value, power of the main battery 220 is applied to the light source. The above-described reference value may mean 2°C. That is, when the outside temperature falls below 2° C., light from the light source 400 is emitted to the outside in the form of a'freezing caution' sign.

Traffic safety signs are classified into caution signs, regulatory signs, instruction signs, auxiliary signs, and road signs.

Among them, auxiliary signs are signs that supplement the main function of caution signs, regulatory signs, or indication signs to inform road users. Examples that are often used on the auxiliary cover are as follows. In other words, there are frequent accident points, detours, emergency calls, foggy areas, icing caution, heavy snow caution, and so on.

However, supplementary signs such as icingism and heavy snowism are only valid in winter and are not suitable for other seasons. Therefore, in case of supplementary signs such as freezing caution and heavy snow caution, it is necessary to replace them with other supplementary signs in seasons other than winter.

However, the luminescent sign of Prior Document 1 has a problem that the replacement cost of the auxiliary sign occurs every year. In addition, the luminescent sign of Prior Document 1 takes a certain amount of time to replace the auxiliary sign. Therefore, there is a problem that it is not possible to respond immediately to a sudden occurrence of freezing or heavy snow.

As traffic accidents at night are the highest among traffic accidents, driving at night requires special attention. In particular, freezing can occur suddenly at night when the temperature drops. Today, due to the mass spread of automobiles, the number of automobile accidents has increased rapidly, and accidents are reported every day, and it is a big social problem. Therefore, there is a need for a method that cannot immediately respond to sudden ice formation or heavy snowfall.

As shown in FIG. 5(b), the optical fiber sign according to an embodiment of the present invention solves the above-described problems of the prior art by displaying different signs in which the light of the light source and the cover sheet according to the temperature. It is done. That is, when the measured value of the temperature sensor is less than the reference value, the power of the main battery is applied to the light source, and accordingly, there is an advantage in that a'freezing warning' sign can be immediately displayed in a situation where there is a risk of freezing.

6 is a front view showing the front panel 120 of the optical fiber sign 10 according to another embodiment of the present invention. 7 is a partial cross-sectional view showing the front panel 120 and the holder 600 of the optical fiber sign 10 of FIG. 6.

6 and 7, the optical fiber sign 10 according to another embodiment of the present invention may display different signs in which light from the light source 400 is different.

As shown in FIG. 6, a first cover sheet 121A and a second cover sheet 121B are attached to the front panel 120. FIG. 6(a) shows that the first cover sheet 121A displays the “slip caution” label, and the second cover sheet 121B displays the “freeze caution” label. The first cover sheet 121A and the second cover sheet 121B may be vertically spaced apart from each other.

As shown in FIG. 7, the light source 400 may include a first light source 400A and a second light source 400B. The first light source 400A and the second light source 400B may selectively emit light by power of the main battery 220. The main control unit 230 may operate a sensor using a micom, and may selectively supply power of the main battery 220 to the first light source 400A or the second light source 400B when the sensor is operated.

The through holes 120H may include a plurality of first through holes 120H1 and a plurality of second through holes 120H2. A first holder 600A may be provided in each of the first through holes 120H1. A second holder 600B may be provided in each of the second through holes 120H2. The first through holes 120H1 are formed in a portion of the front panel 120 to which the first cover sheet 121A is attached. The second through holes 120H2 are formed in a portion of the front panel 120 to which the second cover sheet 121B is attached.

As shown in FIG. 7, the optical fibers 500 may include a plurality of first optical fibers 500A and a plurality of first optical fibers 500B. The first optical fibers 500A transmit light from the first light source 400A to the outside of the case 100 through the first through holes 120H1. The first optical fibers 500B transmit light from the second light source 400B to the outside of the case 100 through the second through holes 120H2.

As shown in FIG. 4, the main control unit 230 may receive a measured value of the temperature sensor 1000. The temperature sensor 1000 measures the temperature of the outside air. Although not shown, the temperature sensor 1000 may be installed in the case 100 or 100 or around the case 100 or 100.

As shown in FIG. 6(b), when the measured value of the temperature sensor 1000 exceeds the reference value, power of the main battery 220 is applied to the first light source 400A. The above-described reference value may mean 2°C.

As shown in FIG. 6C, when the measured value of the temperature sensor 1000 becomes less than the reference value, power of the main battery 220 is applied to the second light source 400B. The above-described reference value may mean 2°C. That is, when the outside temperature falls below 2° C., light from the light source 400 is emitted to the outside in the form of a'slip caution' sign.

That is, as shown in 6, the optical fiber sign 10 according to another embodiment of the present invention, the power of the main battery 220 based on the measured value of the temperature sensor 1000 is the first light source (400A) or By selectively applied to the second light source 400B, there is an advantage of being able to immediately convert a'slip caution' sign into a'freeze caution' sign in a night situation where there is a risk of freezing.

FIG. 8 is a schematic diagram showing the current flow of the optical fiber sign 10 of FIG. 1.

Meanwhile, the main control unit 230 may automatically control the electrical connection between the main battery 220 and the light source 400 at normal times. For example, the main control unit 230 electrically connects the main battery 220 and the light source 400 at 6 o'clock every evening, and disconnects the electrical connection between the main battery 220 and the light source 400 at 6 a.m. I can. The main control unit 230 may include a switch that regulates electrical connection.

In addition, the main control unit 230 may periodically measure the voltage and current of the main battery 220.

As shown in FIG. 8, a reverse flow prevention diode 900 is installed between the main solar cell 210 and the main battery 220, and between the main battery 220 and the main control unit 230, respectively.

A blocking diode (900) prevents reverse flow caused by a string voltage difference. The reverse flow prevention diode 900 prevents power consumption in which the power of the main battery 220 flows backward toward the main solar cell 210.

As shown in FIGS. 1 and 2, the sub power unit 300 supplies power to the light source 400 when the main power unit 200 fails, and is installed in the case 100. Here, the failure of the main power unit 200 may mean a discharge of the main battery 220, a failure of the main solar cell 210 charging the main battery 220, or a failure of the main control unit 230.

As shown in FIG. 8, the sub power unit 300 includes a sub solar cell 310, a sub battery 320, and a sub control unit 330.

The sub-solar cell 310 is provided as a solar cell that generates electricity by converting light energy from the sun into electrical energy. For example, the sub-solar cell 310 may be provided with a solar cell that generates 10W of power energy. The sub solar cell 310 is coupled to the case 100 by a post 310P.

The sub-battery 320 is provided as a secondary battery to charge the electricity produced by the sub-solar cell 310. For example, the sub-battery 320 may be provided as a secondary battery having a capacity of 12V/12A. The sub battery 320 is provided in the sub power box 300B. The sub power box 300B may be coupled to the pillar 10P.

The sub-control unit 330 is a component that controls power of the sub-battery 320 supplied to the light source 400. The sub-control unit 330 may be provided in the sub-power box 300B together with the sub-battery 320.

Normally, the sub-control unit 330 disconnects the electrical connection between the sub-battery 320 and the light source 400. The sub-control unit 330 may include a switch that regulates electrical connection.

In addition, the sub-control unit 330 periodically measures the voltage and current of the sub-battery 320.

As shown in FIG. 8, a reverse flow prevention diode 900 is installed between the sub-solar cell 310 and the sub-battery 320, and between the sub-battery 320 and the sub-control unit 330, respectively. The reverse flow prevention diode 900 prevents power consumption in which the power of the sub battery 320 flows backward toward the sub solar cell 310.

4, the main control unit 230 and the sub-control unit 330 are connected to each other to exchange measurement signals. The above-described measurement signal means a voltage value and a current value of the main battery 220 and a voltage value and a current value of the sub battery 320.

When the voltage value of the main battery 220 is measured to be less than or equal to the set value (11V), the main control unit 230 cuts off the electrical connection between the main battery 220 and the light source 400. This signal is immediately transmitted to the sub-control unit 330, and the sub-control unit 330 electrically connects the sub-battery 320 and the light source 400.

Accordingly, the sub power unit 300 can immediately supply power to the light source 400 when the main power unit 200 fails. Here, the failure of the main power unit 200 may mean a discharge of the main battery 220, a failure of the main solar cell 210 charging the main battery 220, or a failure of the main control unit 230.

Even if the main power unit 200 fails, the optical fiber sign 10 may be normally lit and operated until the main power unit 200 is repaired or replaced. Therefore, it is possible to prevent the occurrence of traffic accidents and losses due to the non-operation of the optical fiber sign 10.

As shown in FIG. 2, a GPS receiver 700 may be provided in the case 100. Although not shown, the communication unit 800 may be provided in the sub power box 300B. The GPS receiver 700 and the communication unit 800 may be controlled by the main control unit 230 and the sub-control unit 330.

Traffic sign (10) is very difficult to check the exact installation location due to the nature of the product installed on the road. In addition, the optical fiber sign 10 has a problem in that it is not possible to check the non-operation and failure of the light source 400 in the daytime due to the characteristics of the product that is lit at night.

In the optical fiber sign 10 according to an embodiment of the present invention, when the main battery 220 is discharged, the sub-control unit 330 transmits the location information of the GPS receiver 700 through the communication unit 800.

The location information of the GPS receiver 700 is automatically transmitted to the manager of the optical fiber sign 10. Therefore, the optical fiber sign 10 according to the embodiment of the present invention has an advantage that the administrator can immediately check the non-operation and failure of the light source 400.

9 is a partial cross-sectional view showing the front panel 120 and the holder 600 of the optical fiber sign 10 of FIG. 1.

3 and 9, the holder 600 is configured to include an exposed portion 610 and an insertion portion 620.

9(a) and 9(b), the exposed part 610 is configured to spread light from the light source 400, and is inserted into the through hole 120H. The exposed portion 610 is inserted into the through hole 120H from the opposite side of the frame 110 with respect to the front panel 120.

As shown in FIG. 9B, the light of the light source 400 transmitted through the optical fiber 500 passes through the head 612. In this process, light from the light source 400 is refracted at the boundary surface of the convex head 612 and spreads widely.

The optical fiber holder for a light emitting sign of Prior Document 2 is made of a material capable of elastic deformation such as rubber, silicone, or synthetic resin having elasticity to perform gripping by elastic deformation.

The light of the optical fiber is difficult to pass through the optical fiber holder made of rubber or silicon. Therefore, the optical fiber intensively emit light corresponding to the safety sign only to the front of the panel. As a result, there is a problem that the light of the optical fiber is rapidly weakened in a direction obliquely to the front of the light-emitting type sign.

9(b), in the optical fiber sign 10 according to an embodiment of the present invention, light from the light source 400 is refracted at the boundary of the convex head 612 and spreads widely, so that the optical fiber sign ( There is an advantage of being able to easily check the light of the optical fiber sign 10 with the naked eye from the front and oblique directions of 10).

10(c), when the insertion part 620 is inserted into the insertion groove 610H, the optical fiber 500 is inserted into the insertion hole 612H. When the optical fiber 500 is inserted into the insertion hole 612H, the amount of light of the optical fiber sign 10 directed to the front of the optical fiber sign 10 increases.

Therefore, while the light of the optical fiber sign 10 can be visually confirmed in a direction oblique to the front of the optical fiber sign 10, the visibility of the optical fiber sign 10 can be increased in front of the optical fiber sign 10 at night.

As shown in FIG. 10A, a protrusion 612P may be formed on the outer surface of the head 612. The protrusion 612P may be formed on the outer surface of the head 612 along the circumferential direction.

As shown in FIG. 10B, when the exposed portion 610 is inserted into the through hole 120H, the protrusion 612P is caught on the outer surface of the front panel 120. Accordingly, the plurality of exposed portions 610 protrude from the front panel 120 to a predetermined height.

As shown in FIG. 10(b), a concave groove 610C may be formed on the inner surface of the insertion groove 610H. In addition, a convex portion 621P may be formed on the outer surface of the body 621.

10(c), when the insertion portion 620 is inserted into the insertion groove 610H, the convex portion 621P is inserted into the concave groove 610C. Accordingly, the exposed portion 610 and the insertion portion 620 form a bonding force.

As shown in FIG. 10(b), an extension part 621D may be formed in the body 621. The extension part 621D may be formed on the opposite side of the head 622 based on the body 621.

As shown in FIG. 10(c), when the insertion part 620 is inserted into the insertion groove 610H, the expansion part 621D is caught on the inner surface of the front panel 120. As shown in FIG. The protrusion 612P and the expansion part 621D are located opposite to each other with respect to the front panel 120. Accordingly, the flow in the direction of the through-hole 120H of the holder 600 is blocked by the protrusion 612P and the expansion portion 621D.

11 is a partial cross-sectional view showing the front panel 120 and the holder 600 of the optical fiber sign 10 according to another embodiment of the present invention. Hereinafter, a description of the same configuration as in the embodiment of the present invention will be omitted.

As shown in FIG. 11(a), a protrusion 612P may be formed on the outer surface of the head 612. The protrusion 612P may be formed on the outer surface of the head 612 along the circumferential direction.

As shown in FIG. 11B, when the exposed portion 610 is inserted into the through hole 120H, the protrusion 612P is caught on the outer surface of the front panel 120. Accordingly, the plurality of exposed portions 610 protrude from the front panel 120 to a predetermined height.

As shown in FIG. 11(b), an extension part 621D may be formed in the body 621. The expansion part 621D may be located opposite to the protrusion 612P based on the through hole 120H.

As shown in FIG. 11(c), when the insertion part 620 is inserted into the insertion groove 610H, the expansion part 621D is caught on the inner surface of the front panel 120. As shown in FIG. The protrusion 612P and the expansion part 621D are located opposite to each other with respect to the front panel 120.

As shown in FIG. 11, the holder 600 may be configured to include an elastic member 630. The elastic member 630 connects the protrusion 612P and the expansion part 621D in the through hole 120H. The elastic member 630 may be provided with a compression spring. The exposed portion 610 may be located inside the elastic member 630.

11(a), a protrusion groove 612PH is formed in the protrusion 612P. One end of the elastic member 630 may be interference fit into the protrusion groove 612PH. A fitting groove 612DH is formed in the expansion portion 621D. The other end of the elastic member 630 may be forcibly fitted into the fitting groove 612DH. The elastic member 630 forms an elastic recovery force that contracts in a state in which the protrusion 612P and the expansion portion 621D are connected.

Metals and synthetic resins have different coefficients of thermal expansion. The coefficient of thermal expansion of synthetic resin is greater than that of metal. That is, the coefficient of thermal expansion of the holder 600 is considerably larger than that of the front panel 120.

Therefore, if the volume of the holder 600 increases in the through-hole 120H in summer, there is a risk of damage to the holder 600. In addition, when the volume of the holder 600 in the through-hole 120H decreases in winter, there is a risk of damage to the holder 600. This is because when the holder 600 contracts, the distance between the protrusion 612P and the expansion portion 621D becomes close.

As shown in FIG. 11(c), the protrusion 612P and the expansion part 621D maintain a state in close contact with the inner and outer surfaces of the front panel 120 by the elastic recovery force of the elastic member 630.

Therefore, even if the distance between the protrusion 612P and the expansion part 621D changes due to thermal expansion or contraction of the holder 600 and the front panel 120, the protrusion 612P and the expansion part 621D are It is possible to maintain a state in close contact with the inner surface and the outer surface of the front panel 120 by the elastic recovery force. Therefore, even if the holder 600 contracts in the through hole 120H in winter, damage of the holder 600 is prevented.

The elastic member 630 is provided between the inner surface of the through hole 120H and the outer surface of the exposed portion 610. That is, the inner surface of the through hole 120H and the outer surface of the exposed portion 610 are spaced apart from each other. Therefore, even if the holder 600 expands within the through hole 120H in summer, damage of the holder 600 is prevented.

Although not shown in detail, the head 622 and the head 612 may be slightly spaced within the insertion groove 610H. Therefore, even if the holder 600 slightly expands in summer, the protrusion 612P and the expansion part 621D can maintain a state in close contact with the inner and outer surfaces of the front panel 120 by recovering the elasticity of the elastic member 630. . Even if the holder 600 expands in summer, the flow of the holder 600 in the through hole 120H is prevented.
