In order to clearly illustrate the present invention, parts not related to the description are omitted, and the same or similar components are denoted by the same reference numerals throughout the specification. Therefore, the above-mentioned reference numerals can be used in other drawings.

In addition, since the sizes and thicknesses of the respective components shown in the drawings are arbitrarily shown for convenience of explanation, the present invention is not necessarily limited to those shown in the drawings. In the drawings, thicknesses may be exaggerated for clarity of presentation of layers and regions.

1 is a view for explaining an optical fiber luminescent labeling apparatus according to an embodiment of the present invention.

Referring to FIG. 1, an optical fiber light emitting diode (SA) according to an exemplary embodiment of the present invention may include a front panel SG and a frame SF. According to the embodiment, the optical fiber light emitting type labeling device SA may further include a solar cell module, a speed measuring sensor, and the like.

The frame SF may include a light source module for driving the front panel SG, a battery, a communication module, and the like, while supporting the front panel SG.

The front panel SG may include a variable display area CD. The front panel SG can display numbers in the variable display area CD. Such a number may be a speed limit or the current speed of the vehicle sensed using a speed measuring sensor.

The segments (S1 to S14) may be located in areas that do not overlap with each other in the variable display area CD.

For example, segments S 1, S 4, S 7, S 8, S 11, S 14 may be longer in a first direction DR 1 than in other directions. Further, the segments S2, S3, S5, S6, S9, S10, S12, S13 may be longer in the second direction DR2 than other directions. The first direction DR1 and the second direction DR2 may be different directions. For example, the first direction DR1 and the second direction DR2 may be perpendicular to each other. For example, the segments S1 to S14 may be hexagonal.

For example, when the segments S1 to S14 are in the hexagonal shape, one end and the other end of each segment may mean two vertexes having the largest interval among the vertexes. Accordingly, the other ends of the segments S1, S4, S7, S8, S11, and S14 may be located in the first direction DR1 from corresponding ends. The other ends of the segments S2, S3, S5, S6, S9, S10, S12, and S13 may be located in the second direction DR2 from corresponding ends.

For example, one end of the segment S1 may be adjacent to one end of the segment S2, and the other end of the segment S1 may be adjacent to the end of the segment S3. One end of the segment S4 may be adjacent to the other end of the segment S2 and the other end of the segment S4 may be adjacent to the other end of the segment S3. One end of the segment S4 may be adjacent to one end of the segment S5 and the other end of the segment S4 may be adjacent to the end of the segment S6. One end of the segment S7 may be adjacent to the other end of the segment S5 and the other end of the segment S7 may be adjacent to the other end of the segment S6.

Similarly, one end of the segment S8 may be adjacent to one end of the segment S9, and the other end of the segment S8 may be adjacent to the end of the segment S10. One end of the segment S11 may be adjacent to the other end of the segment S9 and the other end of the segment S11 may be adjacent to the other end of the segment S10. One end of the segment S11 may be adjacent to one end of the segment S12 and the other end of the segment S11 may be adjacent to the end of the segment S13. One end of the segment S14 may be adjacent to the other end of the segment S12 and the other end of the segment S14 may be adjacent to the other end of the segment S13.

The front panel (SG) can display numbers in segment units. For example, segments S3 and S6 may be lit to indicate the number 1, and the remaining segments may be turned off. It is also possible to turn on the segments S1, S3, S4, S5, S7 to display the number 2 and turn off the remaining segments. It is also possible to turn on the segments S1, S3, S4, S6, S7 to display the number 3 and turn off the remaining segments. Also, the segments S2, S3, S4, and S6 may be turned on to illuminate the number 4, and the remaining segments may be turned off. It is also possible to turn on the segments S1, S2, S4, S6, S7 to display the number 5 and to light off the remaining segments. It is also possible to turn on the segments S1, S2, S4, S5, S6, S7 to display the number 6 and turn off the remaining segments. It is also possible to turn on the segments S1, S2, S3, S6 to display the number 7 and turn off the remaining segments. Also, it is possible to turn on the segments S1, S2, S3, S4, S5, S6, S7 to display the number 8 and turn off the remaining segments. It is also possible to turn on the segments S1, S2, S3, S4, S6, S7 to display the number 9 and to light off the remaining segments. Also, it is possible to turn on the segments S1, S2, S3, S5, S6, S7 to display the number 0 and turn off the remaining segments.

When the above-described ON / OFF method is used, a number from 0 to 99 can be displayed in the variable display area CD of FIG. However, in another embodiment, a number from 0 to 999 may be displayed by further having seven segments corresponding to the segments S1 to S7. Similarly, the more number of seven segments in the variable display area CD, the more the representable number can be increased by 10 times.

2 is a view for explaining a connection relationship between a segment and a light source module according to an embodiment of the present invention.

Referring to Fig. 2, a segment S1 and a light source module LSM are shown. The other segments S2 to S14 may also be connected in substantially the same manner as the corresponding light source module, and therefore redundant description is omitted.

Segment S1 may include exit apertures OH. Each exit port (OH) can be connected to one end of the optical fiber (OF). According to the embodiment, the exit portion OH may be further provided with a fitted portion FU, and one end of the optical fiber OF may be fitted to the fixed portion FU.

The exit apertures (OH) may be arranged at regular intervals from one another in the corresponding segment (S1). For example, the exit apertures (OH) may be arranged in a matrix form. The row direction may be a first direction DR1, and the column direction may be a second direction DR2. However, the matrix does not mean that each row and column must include the same number of exit apertures (OH). Referring to FIG. 2, the outgoing ports OH included in the middle row CR are the largest, and the outgoing ports OH included in the edge rows UR and LR are the smallest.

Each light source module LSM is connected to only one corresponding segment. Therefore, the numbers described with reference to Fig. 1 can be variably displayed by adjusting the ON / OFF of each light source module LSM.

3 is a view for explaining a light source module according to an embodiment of the present invention.

Referring to FIG. 3, the light source module LSM according to an embodiment of the present invention may include a frame MF, light sources LS, a circuit board CB, and lenses LE.

The frame MF may be in the form of a barrel. The other ends of the optical fibers (OFs) can be fitted into the frame (MF) in the form of dense bundle-shaped binding portions (OFe). The frame MF may be made of various materials such as metal and plastic, and may diffuse or reflect the internal light.

The light sources LS may be composed of elements such as light emitting diodes (LEDs). The light sources LS can emit light of the same color to each other. In another embodiment, the light sources LS may be composed of a plurality of groups to emit light of different colors. According to this embodiment, there is an advantage that one segment can be emitted in different colors without reducing the resolution of the variable display area CD.

The light sources LS may be disposed on the circuit board CB. The circuit board CB can be opposed to the coupling portion OFe in a planar shape.

The lens layer LEl may cover the light sources LS and the circuit board CB. The lens layer LEl may be composed of various transparent materials such as glass or plastic. The lens layer LE1 may include lenses LE. Each of the lenses LE may be composed of a convex lens, a TIR (Total Internal Reflection) lens, or the like, and may narrow the light angle of light emitted from the light sources LS.

According to the present embodiment described above, since the light sources LS are not exposed to the outside through the front panel SG, the optical fiber luminescent type labeling apparatus SA which is resistant to external shocks such as moisture and vibration can be provided.

In addition, even if a part of the light source LS fails, light can be incident / emitted to all the optical fibers OF by the other light sources LS of the light source module LSM, so that the segment can still be turned on / off Do. At this time, the luminance of the segments including the failed light source LS may be lower than the luminance of other segments having normal brightness. According to an embodiment of the present invention, the light sources LS included in each light source module LSM may be electrically connected in parallel, and one electrode of the light sources LS may be connected to a common constant current source. Therefore, when a part of the light source LS fails, the current corresponding to the failed light source LS is dispersed and flows in the other light sources LS, so that the other light sources LS can emit light with higher luminance. Therefore, according to the embodiment, by automatically increasing the luminance of the segment of the failed light source LS, the luminance difference from the other segments can be reduced.

Further, according to the present embodiment, since each light source does not constitute the pixels of the front panel SG but each emission aperture OH constitutes the pixels of the front panel SG, The number of light sources LS is small. Therefore, the power consumption can be reduced.

FIGS. 4 and 5 are views for explaining a structure for implementing a preferable emission angle according to an embodiment of the present invention.

Referring to FIG. 4, a first road ROAD1, a second road ROAD2, and an optical fiber type light emitting device SA according to an embodiment of the present invention are shown.

The optical fiber light emitting type indicating apparatus SA needs to provide the vehicle CAR with road information at a luminance level higher than a certain level. At this time, as the outgoing light angle " ag " of the optical fiber light emitting type indicating apparatus SA becomes narrower, the amount of light can be concentrated, so that power consumption can be reduced.

For example, when the outgoing light angle ag_e is 15 degrees, the installation of the optical fiber luminescent type indicator SA at the distance d1 from the target point on the first road ROAD1 having the width w1 of 14 m is It is possible. When the outgoing light angle ag_e is 15 degrees, it is possible to mount the optical fiber luminescent type SA at a distance d2 of 200 m from the target point on the second road ROAD2 having the width w2 of 53 m .

In general, the speed measurement sensor is optimized at a distance of 50 m. Considering that the total lane width is 14 m based on a four-lane road, the emission angle of the optical fiber light emitting type SA is preferably 15 degrees.

However, since the variable angle marking device of the conventional LED display panel is applied with the wide angle of light (over 60 degrees) of the LED itself, it is difficult to satisfy the optimum distance condition and light pollution can be caused by the light emitted to the outside of the road.

Referring to FIG. 5, the outgoing light angle ag1 of the light source LS may be 60 degrees as described above. According to this embodiment, the lens LE can reduce the outgoing light angle ag2 to about 8 to 10 degrees. Light having passed through the lens LE may be incident on the incident surface IP of the optical fiber OF and may be output to the exit surface OP through a total reflection process.

The optical fiber (OF) in a straight line state can theoretically be the same as the incident wide angle. However, in general, the optical fiber light emitting type labeling device SA may have a size of about 1 m, and the length of the optical fiber OF may be about 1 m. Therefore, the optical fiber OF on the internal structure can be bent, and a curvature of about 30 mm in radius of curvature can occur over an area of about 50 mm. Under this condition, the incident wide angle contrast output angle wide angle can be increased by about 50%, and therefore, the output wide angle ag3 of the optical fiber OF can be about 15 degrees.

According to the present embodiment, the exit surface OP of the optical fiber OF is polished close to a mirror surface, so that the emitted light can maintain straightness without scattering.

As described so far, the power consumption of the light source used in the speed measuring sensor and the segment display with high power consumption can be optimized, so that the solar cell module can be driven without a commercial power supply.

Also, in the week during frequent vehicle traffic, it is possible to extend the life of the battery by reducing the number of charge / discharge cycles of the battery by using the electric power generated from the solar battery module as it is and by reducing the operation period of the speed measurement sensor at night, The power consumed can be minimized.

According to one embodiment, the Doppler echo signal reflected from the vehicle can be analyzed to detect the speed of the vehicle and the vehicle traffic amount, thereby varying the Doppler emission period, so that the power saving mode can be switched Can be designed. In addition, the power generated by the solar cell module can be bypassed without going through the battery during the weekday when vehicle traffic frequently occurs, thereby minimizing power consumption and driving the solar cell module alone.

The data output from the speed measurement sensor can be stored by traffic volume, speed over frequency, type of vehicle, time of day, and can be transmitted using a communication module. According to the analysis results of these data, if the rate limiting effect is low, it can be used to improve the rate limiting effect by adjusting and strengthening the speed display method, the visibility level, and the display (warning) method.

  The type, speed, and distance of the vehicle can be calculated using the dual antenna radar sensor and the dedicated signal processor, and the deceleration inducing information can be expressed in real time through the illuminant of the sign.

  It communicates with the control server through the low power wide area communication module in real time. By providing the collected information to the management personnel, it is possible to manage safety according to the traffic statistics of places where speed management is required. It can also be used for policy making.

6 to 8 are views for explaining a connection relationship between a segment and a light source module according to another embodiment of the present invention.

6 to 8, the segment S1 may include first outgoing apertures OH1 and second outgoing apertures OH2.

The first outgoing ports OH1 may be connected to the first light source module LSM1 through optical fibers and the second outgoing ports OH2 may be connected to the second light source module LSM2 through optical fibers.

The first emitting means OH1 may be arranged in the form of first lines extending in a first specific direction. In addition, the second outgoing apertures OH2 may be arranged in the form of second lines extending in a first specific direction. At this time, the first lines and the second lines may alternately be positioned in the second specific direction different from the first specific direction.

For example, the segment S1 may be longer in a first direction DR1 than in other directions. 6, the first outgoing apertures OH1 are arranged in the form of first lines extending in a first direction DR1 and the second outgoing apertures OH2 are arranged in a first direction DR1, Two lines, and the first lines and the second lines may be alternately arranged in the second direction DR2.

According to the embodiment of FIG. 6, even if the first light source module LSM1 fails, the light emission through the second exit ports OH2 can be controlled by the second light source module LSM2, It can be turned on / off. In addition, by separating into two light source modules (LSM1, LSM2), the load applied to each light source module is reduced to 1/2, and the light source heat generation corresponding to the reduced load can be reduced.

7, the first outgoing apertures OH1 are arranged in the form of first lines extending in the second direction DR2 and the second outgoing apertures OH2 are arranged in the second direction DR2, And the first lines and the second lines may be alternately arranged in the first direction DR1.

According to the embodiment of FIG. 7, when the first light source module LSM1 fails, the segment S1 may be turned on in a vertical stripe pattern by the second light source module LSM2. Here, the first direction DR1 means the transverse direction and the second direction DR2 means the longitudinal direction. In a similar case, in the embodiment of FIG. 6, the segment S1 may be lit in a horizontal striped pattern. Considering the length of the segment S1, since the light concentration of the horizontal stripe is higher than that of the vertical stripe (if only the second emitting apertures OH2 emit light, the horizontal stripe is a long two-row light, Light emission), the user can visually inspect the horizontal stripes relatively more strongly. Thus, according to the present embodiment, even if one light source module fails, the failure may be relatively less visibly or unapproved.

8, the first outgoing apertures OH1 are arranged in the form of first lines extending in the diagonal direction of the first direction DR1, and the second outgoing apertures OH2 are arranged in the first direction DR1 in the first direction DR1. The first lines and the second lines may be alternately arranged in a direction perpendicular to the oblique direction.

According to the embodiment of FIG. 8, even if one of the light source modules fails, it is possible to prevent the occurrence of a failure in the first direction DR1 and the second direction DR2, which are array directions of the segments S1 to S14, The possibility that the failure is visually recognized by the user is low. Referring to FIG. 8, the second outgoing apertures OH2 are arranged at regular intervals from each other, and the first outgoing apertures OH1 may be arranged at regular intervals from each other, so that the stripe form itself may not be expressed. In this case, by increasing the brightness of the normal light source module, the segments may be viewed as if they are operating normally.

Referring to FIG. 9, the front panel SG 'of the optical fiber light emitting type display device SA' according to another embodiment of the present invention may further include a fixed display area FD.

10, the variable display area CD "of the optical fiber light emitting type labeling device SA" according to another embodiment of the present invention may be in the form of a separate sub-panel that can be assembled with the front panel SG " .

The front panel SG "except for the variable display area CD " may be formed by attaching a color sheet or a black matte sheet to an aluminum plate.

The subpanel corresponding to the partial display area (CD ") may be formed by attaching a black matte sheet to an aluminum plate or a black plastic injection molding material. When using a black plastic injection material, The surface can be processed with a concave-convex structure.

Also, each of the segments S1 to S14 in the variable display area may be in the form of a separate sub-panel that can be assembled independently. That is, in FIG. 10, fourteen independent sub-panels may constitute the respective segments S1 to S14.
