1 to 6, the school zone light panel device according to an embodiment of the present invention is formed of a transparent material so that light can be transmitted through the front surface, and a housing 100 and a housing ( It is installed in the front direction of the inner space of 100), and is installed on the rear of the information film 200 and the information film 200 of a transparent material on which predetermined pictures and characters are drawn, and is made of a transparent or semi-transparent material so that light can be transmitted. It is formed, and a plurality of light guide grooves 310 are formed in the shape of a flat plate in which a plurality of light guide grooves 310 are engraved on the rear surface so as to guide the scattering of light in the front direction, and are coupled to one side of the light transmitting part 300 to be coupled to the light transmitting part ( 300) It is installed on the rear side of the first light-emitting part 320 and the light-transmitting part 300 to irradiate light inside, and induces the light irradiated from the first light-emitting part 320 to be transmitted to the front direction of the light-emitting part 300 And, it is installed on the rear surface of the reflective film 400 and the reflective film 400 in which a plurality of through holes 410 forming a predetermined picture and character different from the information film 200 are formed, and formed in the reflective film 400 It is configured to include a second light emitting unit 500 in which a plurality of lights 510 are installed at a position corresponding to the ball 410.

The school zone light panel device is installed near the crosswalk in the school zone, and is installed to deliver information to drivers of vehicles approaching the school zone crosswalk. This will be described in more detail in the school zone light panel system to be described later.

The housing 100 is preferably formed to be divided into two parts of the front housing 110 and the rear housing 120, and the two components are engaged and coupled to each other to form a predetermined internal space therebetween. At this time, the inner space is preferably formed in a hexahedral shape, but may be transformed into a cylindrical shape or other various shapes as necessary.

A front window 111 made of a transparent material is formed on the front housing 110 and is provided so that the information film 200 can be visually recognized through this. Since the front window 111 has a child protection area sign printed, it is possible to indicate that this is a child protection area without additional backlighting.

Information for notifying the driver that this is a school zone, for example, a child protection zone sign 210 and a slow sign 220 are printed on the information film 200. Such information is not clearly exposed to the outside when the power of the first light-emitting unit 320 is turned off, but can be clearly revealed when light is supplied through the first light-emitting unit 320 and the light-transmitting unit 300 to be described later. .

The light-transmitting part 300, also known as a light guide plate, reflects the light supplied from the first light-emitting part 320 forward, and transmits light that is projected from the first light-emitting part 320 and flows forward along one side. In order to guide it, a plurality of light guide grooves 310 are provided in a flat plate shape in which a plurality of light guide grooves 310 are engraved.

At this time, the light guide groove 310 is formed in a shape such as a hemispherical shape or a semi-elliptical shape, and is engraved on the bottom surface of the light transmitting part 300.

Accordingly, as the light projected from the first light-emitting part 320 into the light-transmitting part 300 through one side of the light-transmitting part 300 is scattered from the boundary surface of the light-guide groove 310, the front surface of the light-transmitting part 300 It is discharged to the outside through the information film 200 that is stacked on the front.

More preferably, in the light-transmitting part 300 according to an embodiment of the present invention, a plurality of light-guide grooves 310 are combined with the first light-emitting part 320 to increase the density per unit area from one side to which light is supplied to the other side, that is, It is provided to have a light-transmitting pattern with increased density.

Specifically, the light guide groove 310 has a density of the light guide groove 310 from one side where the first light emitting unit 320 is installed to the other side so that it is uniformly projected within a preset reference illuminance range in the entire area of the light transmitting unit 300. It is preferable that it is formed to increase gradually.

Because, the light generated from the first light-emitting part 320 and introduced into one side of the light-transmitting part 300 toward the other side of the light-transmitting part 300 toward the front of the light-transmitting part 300 by the light-guide groove 310 As the amount of reflected reflection gradually increases, the intensity of light, that is, the intensity of light gradually decreases, so that the density of the light transmitting unit 300 is differentiated from one side of the light transmitting unit 300 to the other side. By allowing light to be projected with even illuminance, there is an effect of minimizing eye fatigue that the driver feels, and minimizing the occurrence of distortion caused by differences in illuminance, and thus improving visibility.

Looking at the first light-emitting part 320 in more detail, a plurality of light-emitting elements 321 installed on the edge of one side of the light-transmitting part 300 to irradiate light, and an inner surface to surround the edge of the light-emitting part 300 The light-emitting element 321 is installed inside the open frame shape, and the heat generated from the light-emitting element 321 is discharged to the outside, and light leaking through the side of the light-transmitting part 300 is transferred into the light-emitting part. A light-emitting frame 322 that reflects, a first sealing member 323 that is made of a transparent material that transmits light and fills the interior of the light-emitting frame 322 and seals the light-emitting element 321, and an opaque material so that light does not pass through It is configured to include a second sealing member 324 for sealing the coupling portion between the light emitting frame 322 and the light transmitting part 300.

The light emitting device 321 may be a cold cathode ray lamp (CCFL) or a light emitting diode (LED) as a light source for generating light supplied to the inside of the light emitting unit 300, but energy consumption like a light emitting diode (LED) is It is desirable to select and use a light source that is low and excellent in illuminance.

The light-emitting frame 322 has a cross-section of a "?quot; type" so as to surround the edge of the light-transmitting part 300. This light-emitting frame 322 is advantageous for light reflection, excellent heat dissipation, and resistance to moisture. It is preferably made of an aluminum alloy having excellent corrosive properties.

Because, by discharging the heat generated from the light-emitting element 321 of the light-emitting frame 322 to the outside, the light-emitting element 321 should be prevented from being deteriorated or changed, and through the side of the light-transmitting unit 300 to the outside. This is because it is necessary to reflect the emitted light back into the light transmitting part to minimize the loss of light generated from the light emitting device 321 and to minimize energy consumption during advertisement.

In this case, the light emitting frame 322 is divided into a first area in which the light emitting element 321 is installed and a second area in which the light emitting element 321 is not installed.

Specifically, in the first region of the light emitting frame 322, a plurality of light emitting elements 321 are spaced apart from each other along one side of the light transmitting part 300 in the longitudinal direction to supply light to the light transmitting part 300, and the second The region simply serves as a heat sink and reflects light from the inside without the light emitting element 321.

Meanwhile, a first sealing member 323 that is filled in the first region of the light-emitting frame 322 and fixes the light-emitting element 321 to the inner wall of the first region of the light-emitting frame 322 and watertight the light-emitting element 321 Wow, by installing a second sealing member 324 sealing the gap between the light emitting frame 322 and the light transmitting part 300, the electrical circuit is exposed to prevent moisture from flowing into the light emitting device 321 vulnerable to external moisture. There is an effect of improving the life of the light emitting device 321 by preventing.

Thus, even if moisture flows into the first region of the light emitting frame 322 in which the light emitting element is located due to damage or wear of the second sealing member 324, the second sealing member 324 is By preventing exposure, there is an effect of preventing malfunction and failure of the light emitting device 321.

At this time, the first sealing member 323 is provided with a transparent material so that the light generated from the light emitting device 321 can pass through, but does not cause discoloration or deformation due to heat generated from the light emitting device 321. It is preferable that the heat-resistant temperature is made of a heat-resistant resin higher than the heat-generating temperature of the light emitting device 321.

Accordingly, there is an effect of improving the visibility of the mark drawn on the information film 200 by allowing the light generated from the light emitting device 321 to be smoothly transmitted to the front of the light transmitting unit 300 through the light transmitting unit 300. .

The reflective film 400 basically reflects the light transmitted through the rear surface of the light-transmitting part 300 when the light generated from the first light-emitting part 320 flows into the light-transmitting part 300 to reflect the light transmitted through the light-transmitting part 300. It is a configuration to transmit in the front direction of ). To this end, a reflective coating is formed on the front surface of the reflective film 400 and is configured to reflect most of the light.

Meanwhile, a through hole 410 is formed in the reflective film 400 to form a predetermined shape, and the through hole 410 is a configuration for passing light emitted from the illumination 510 of the second light emitting unit 500. .

The second light-emitting unit 500 is a configuration for generating light from the lighting 510 made of, for example, an LED element, and the lighting 510 is arranged to form a predetermined shape, for example, a speed limit sign 600 It is desirable to be. In addition, the through hole 410 of the reflective film 400 described above is also formed to form the same arrangement as the arrangement of the lighting 510, so that the light of the lighting 510 passes through the light transmitting part 300 without interference and thus the housing 100 It is provided to be transmitted in the front direction of ).

Meanwhile, a rear window 121 is formed on the rear housing 120, and through this, the display unit 10 installed inside the housing 100 can be visually recognized.

Through this, you can check surrounding information.

Meanwhile, as shown in FIGS. 1 to 7, the school zone light panel system according to the present invention includes a light panel device 10, a sensor unit 2, and a control unit 3.

Among them, the light panel device 1 is the same as the school zone light panel device 1 described above, and redundant descriptions will be omitted.

The sensor unit 2 senses a vehicle passing through the school zone, generates the position and speed information of the vehicle, and transmits it to the control unit 3, and the position of the vehicle C approaching the crosswalk in the school zone and You can measure the speed.

The control unit 3 controls the light panel device 10 based on the information transmitted from the sensor unit 2 to provide appropriate information to the driver of the vehicle C operating the school zone.

Looking at the configuration of the control unit 3 in more detail, when the position of the vehicle C detected by the sensor unit 2 is within a preset first distance from the crosswalk of the school zone and is greater than the second distance, the first light emitting unit A first mode (Fig. 1(b)) in which light is generated at 320 and the power of the second light-emitting unit 500 is cut off to visually transmit information drawn on the information film 200 to the driver of the vehicle, When the position of the vehicle detected by the sensor unit 2 is within a preset second distance from the crosswalk of the school zone, the power of the first light emitting unit 320 is cut off and light is generated from the second light emitting unit 500 Thus, the second mode (Fig. 1(c)) for visually transmitting information displayed by the reflective film 400 and the second light emitting unit 500 to the driver of the vehicle can be variably switched.

At this time, the first distance range is set to be wider than the second distance range. For example, when the first distance is 100m, the second distance is 50m, and there are a plurality of vehicles detected by the sensor unit 2, the controller 3 ) Can be controlled based on the location of the vehicle C closest to the crosswalk in the school zone.

That is, when the vehicle (C) is in the range of the first distance to the second distance from the crosswalk, information enough to call the attention of the driver of the vehicle (C), that is, child protection printed on the information film 200 The zone sign 210 and the slow sign 220 are provided, and if the vehicle C is within the second distance from the crosswalk, it will warn the driver of the vehicle C to pay more attention. For the purpose, by displaying a speed limit sign 600 of a size larger than that of a normal sign, it is possible to allow the driver to pay more attention.

On the other hand, since the vehicle may always be located in the area within the second distance in the area where the vehicle C passes much, it is possible to set the mode change by installing the traffic light sensor 4 connected to the crosswalk traffic light.

That is, in a situation where the vehicle C exists within the range within the first distance, if the signal transmitted from the traffic light sensor 4 is a pedestrian stop signal, it operates as in the first mode described above, and is transmitted from the traffic light sensor 4 If the signal is a pedestrian traffic signal, it may be set to operate as in the second mode described above.

By changing the information displayed according to the presence or absence of the vehicle C and the signal state of the traffic light, it is possible to make the driver of the vehicle C visually recognize a warning sign appropriate to the situation.

In addition, when there is no vehicle, power to the first light-emitting unit 320 and the second light-emitting unit 500 is cut off, thereby minimizing unnecessary waste of power. (Fig. 1 (a))

Even when the power is cut off in this way, the sign of the child protection area installed on the front window 111 remains, and minimal information that this is a child protection area can always be provided.

On the other hand, a display unit 10 is installed on the rear of the light panel device 10, and the display unit 10 provides not only surrounding maps and living information, but also surrounding traffic information and traffic statistics, etc. Pedestrians can recognize that this is a dangerous place.
