In general, in order to ensure safe and smooth road traffic on all roads such as city roads, national roads, and expressways, road information (road information) is provided on the road side of the road or on the roads A road sign is provided. In this typical road sign, a sign (letter, number, or mark pattern) for guiding road information is manufactured as a reflection sheet and attached to the plate signboard body, so that the road information can be easily guided to the driver.

However, in recent years, a light emitting type signboard has been spreading, which provides illumination to a sign board body so as to improve visibility of road information. In particular, such a light-emitting type signpost provides illumination along the sign of the main body, so that the road information can be clearly displayed.

The bundle insertion socket is formed by pressing one end of the light reflection tube on one side and clamping the locking projection on the other side so that the pipe of the optical cable bundling portion is inserted and fixed. Such conventional light emitting type road signs emit various kinds of sign patterns or signs provided on the sign board through LEDs and optical cables.

However, since the conventional light-emitting type signboard operates only at a set time, especially at night, in order to save energy by using an external power source (power source of a power station), the sign of the sign is visually recognized during daytime or nighttime fog, There is a problem that is very difficult, and seriously, there is a problem that a serious accident occurs because the notice on the sign can not be grasped.

Especially, in recent years, problems such as the occurrence of 70 or 130 collision accidents in bridges have been caused due to failure to grasp precautions of signs installed on the roads due to fog.

Hereinafter, referring to the accompanying drawings, a humidity-responsive light-emitting type sign capable of automatically operating upon occurrence of fog according to an embodiment of the present invention will be described.

1 to 3, a sign board according to an embodiment of the present invention includes a cover panel 110, a case 120, a lamp module 130, a lamp driving module 150, a power supply unit 140, And a humidity sensing module (160).

The cover panel 110 may be formed of a thermoplastic plate material such as plastic, acrylic or polycarbonate or a metal plate, and a sheet having a symbol for guiding road information or a sheet cut in a symbol shape is attached to the front side. Such a sheet is preferably composed of a reflective sheet.

The case 120 is a component that shields the rim and rear of the cover panel 110 described above. The case 120 may be configured to include, for example, a frame 121 and a rear cover 123 as shown in FIG.

The rim frame 121 is formed in a hollow ring shape having both sides penetrated as shown in Fig. The frame 121 may be formed of a polygon such as a square, a triangle, or a hexagon, or alternatively, a circle, an ellipse, or a semicircle. For example, the edge frame 121 is manufactured by hollowing a metal plate (for example, aluminum) which is long-extruded in the form of a band to a predetermined length after bending the metal plate into a ring shape, and both ends of the metal plate, And they are connected by welding or the like to form an annular shape.

As shown in Fig. 1, the frame 121 is provided with a fitting groove 121a, which is fixed at the distal end thereof with the rim of the cover panel 110 described above fitted therein, on the inner peripheral surface of the leading end side. As shown in the drawing, the frame 121 is provided with a latching protrusion 121b, which is supported on the inner circumferential surface of the rear end side by hanging a rim of the rear cover 123, which will be described later. The frame 121 may be formed with the metal plate together with the fitting groove 121a and the engaging step 121b when the metal plate is extruded. In this case, the fitting groove 121a and the engaging step 121b are provided along the inner peripheral surface of the frame 121 formed in a ring shape.

The rear cover 123 is formed of a plate material as shown in Fig. 1, and is provided with a grill-shaped ventilation grill portion 121c through which air is communicated. The rear cover 123 may be provided with a shielding plate for shielding the ventilation grill portion 121c to block the chips of insect and moisture. The blocking plate may be formed of, for example, a sheet ST of a Gore-Tex material as shown by a broken line in FIG. 1, and may be fixed to the rear cover 123 with an adhesive, a tape, or the like.

The lamp module 130 includes a PCB substrate on which the LED lamp 131 is mounted, as shown in FIG. The lamp module 130 provides illumination light inside the case 120 through the LED lamp 131. The lamp module 130 may be mounted inside the optical fiber sleeve 100c as described below. The lamp module 130 operates (turns on or off) the LED lamp 131 by a power source input from the power supply unit 140.

The lamp driving module 150 controls driving of the lamp module 130 according to a sensed value sensed by the humidity sensing module 160 to be described later, thereby lighting the LED lamp 131. [ The lamp driving module 150 may include a power input unit 151, a switching unit 153, a driving unit 157, a communication unit 155, and a driving module substrate 159, for example, as shown in FIG.

The power input unit 151 receives power from the power supply unit 140 and provides the power to the switching unit 153.

The switching unit 153 is switched by the driving signal of the driving unit 157 and applies or cuts off the power provided from the power input unit 151 to the lamp module 130 described above. Accordingly, the lamp module 130 turns on or off the LED lamp 131 by the power supplied through the switching unit 153. [

The driving unit 157 generates a driving signal for driving the switching unit 153 based on the signal from the humidity sensing module 160 and provides the driving signal to the switching unit 153. Particularly, the driving unit 157 generates a driving signal and supplies the driving signal to the switching unit 153 when a signal for confirming mist or rain (including snow) is applied from the humidity sensing module 160. That is, the driving unit 157 generates the driving signal when the humidity sensing module 160 receives the "confirmation signal " for confirming the mist or rain, and provides the driving signal to the switching unit 153. [ Alternatively, the driving unit 157 compares the sensed value (humidity value) applied in real time in the humidity sensing module 160 with a predetermined comparison value (fog or rainfall occurrence value) capable of judging fog or rainfall, It is possible to generate the driving signal and provide the driving signal to the switching unit 153. [ At this time, the driving unit 157 adjusts the temperature value and the sensing value (humidity value) applied from the temperature controller (not shown) to a predetermined comparison value (mist or rainfall occurrence temperature value and humidity value) The driving signal may be generated.

The driving unit 157 may generate the driving signal according to the predetermined driving time and provide the driving signal to the switching unit 153, unlike the above. For example, the driving unit 157 generates a driving signal for turning on the LED lamp 131 when the set driving time (e.g., night) starts, and supplies the driving signal to the switching unit 153. When the driving time is completed The driving signal for turning off the LED lamp 131 is supplied to the switching unit 153. Therefore, the LED lamp 131 is lit only at night, and can be turned off during the daytime.

The communication unit 155 receives the signal applied from the humidity sensing module 160 and transmits the signal to the driving unit 157 described above.

The drive module substrate 159 is formed of a PCB substrate as shown in FIG. 4 and includes elements and circuits constituting the power input unit 151, the switching unit 153, the drive unit 157, and the communication unit 155 Respectively. The drive module substrate 159 may be embedded in a substrate storage box 170, which will be described later, as shown.

The power supply unit 140 supplies power to the lamp driving module 150 or the humidity sensing module 160, which will be described later. The power supply unit 140 may be configured to supply power to the power plant, but it is preferable that the power supply unit 140 is configured to supply power using solar energy. For this purpose, the power supply unit 140 may include a solar panel 141 and a battery 143, for example, as shown in FIG.

The solar panel 141 may be separately provided outside the case 120 as shown or may be mounted on the case 120 described above. The battery 143 stores electrical energy produced by the solar panel 141. The battery 143 may be provided separately on the outside of the case 120 or on the inside or outside of the case 120. The battery 143 is preferably installed in the battery compartment as shown.

On the other hand, the humidity sensing module 160 senses the outside humidity of the case 120 and applies a signal according to the sensed humidity to the lamp driving module 150. The humidity sensing module 160 may include a sensor 161, a comparing unit 163, an interface unit 165, and a sensing module substrate 167, for example, as shown in FIG.

1, the sensor 161 is mounted on the outside of the case 120 or the cover panel 110 so as to expose the humidity sensing part, thereby sensing the outside humidity of the case 120. The sensor 161 may be a conventional humidity sensor and can sense the humidity as described above. Alternatively, the sensor 161 may be configured with a normal temperature and humidity sensor to sense the temperature and humidity. Thus, the sensor 161 provides a sensed value for the sensed humidity or temperature and humidity.

The sensor 161 may comprise, for example, a probe 161a and a sensing wire 161b as shown in the figure. 1, the probe 161a is a sensing element mounted at least partially on the outside of the case 120 or the cover panel 110. The probe 161a is configured to detect the outside humidity and temperature / humidity of the case 120 in real time . It is preferable that the probe 161a is exposed to the outside of the case 120 through the ventilation grill portion 121c of the rear cover 123 as shown in the figure and that the ventilation grill portion 121c is provided with the above- A part of the sheet ST can be mounted to be exposed to the outside of the case 120 through a cleaved gap. That is, the probe 161a may be exposed to the outside of the vent grill portion 121c through the cut-out portion C of the sheet ST cut out for penetration as shown in FIG. The probe 161a transmits the sensed sensed value to the driving unit 157 of the lamp driving module 150 or to the comparing unit 163 to be described later.

The sensing wire 161b may be constituted by an electric wire for transmitting the humidity and the temperature and humidity measured by the probe 161a to the comparing unit 163. [ One end of the sensing wire 161b is connected to the sensing module substrate 167 and the other end is connected to the probe 161a. Accordingly, the sensing wire 161b transmits the sensing value of the probe 161a to the comparing unit 163. [

The comparing unit 163 compares the sensing value applied from the sensor 161 with the predetermined comparison value (fog or rainfall occurrence value), and if the sensing value corresponds to a predetermined comparison value, the lamp driving module 150 To the lamp driving module 150 through the interface unit 165 to be described later. That is, the comparator 163 transmits the above-mentioned "confirmation signal " for confirming the driving signal for driving the lamp driving module 150 or the mist or rain. At this time, the comparator 163 may apply a driving signal to the driving unit 157 so that the driving unit 157 of the lamp driving module 150 applies the driving signal to the switching unit 153, The switching unit 153 may be operated by directly applying a signal to the switching unit 153. [ Therefore, the lamp driving module 150 can turn on the LED lamp 131 of the lamp module 130 by the driving signal of the comparing unit 163. [

When only the humidity value is applied from the sensor 161, the comparison unit 163 compares the temperature value applied from the temperature sensor (not shown) and the humidity value of the sensor 161 with a preset humidity value It is also possible to generate the driving signal by comparing it with the comparison value (the mist or the rainy season occurrence temperature value and the humidity value).

The interface unit 165 applies the signal generated by the comparison unit 163 to the communication unit 155 of the lamp driving module 150 described above. At this time, the interface unit 165 may apply the above-described driving signal generated in the comparison unit 163, and may otherwise apply the above-described "confirmation signal " generated in the comparison unit 163.

The sensing module substrate 167 is formed of a PCB substrate as shown in FIG. 4, and elements constituting the sensor 161, the comparison unit 163, or the interface unit 165 are mounted. At this time, the sensing module substrate 167 is embedded in the substrate storage box 170, which will be described later.

Meanwhile, the sensing wire 161b can be easily fixed to the rear cover 123 of the case 120 through the clamp 125 as shown in FIG. That is, the case 120 may further include a clamp 125. 1, the clamp 125 may be made of a ring-shaped elastic clamp, which is attached to one side of the rear cover 123 with a screw, an adhesive, a tape or a magnet, and is open at one side. The sensing wire 161b is fitted and fixed to the elastic clamp so that it is easily fixed to the rear cover 123. [

Here, the above-mentioned clamp 125 may be constituted by a double-sided tape for detachably attaching the sensing wire 161b to the rear cover 123. [ In this case, the sensing wire 161b can be easily attached to the rear cover 123. [

In addition, the sensing wires 161b may be divided into a pair as shown in Fig. The sensing wire 161b is connected to a fixed connector 161b-1, one of which is fixed to the rear cover 123 by bolting, and the other is connected to the frame 121 And is connected to a coupling connector 161b-2 fixed to the fixed connector 161b-1 by bolting. At this time, the sensing wire 161b connected to the fixed connector 161b-1 of the pair of sensing wires 161b is connected to the probe 161a of the sensor 161 as shown in the figure. The remaining sensing wires 161b connected to the coupling connector 161b-2 are connected to the above-described sensing module substrate 167 as shown in the figure. The pair of sensing wires 161b are arranged such that when the rear cover 123 is engaged with the frame 121, the fixing connector 161b-1 of the rear cover 123 naturally contacts the engaging connector 161b- Are easily connected integrally to each other as they are coupled to the first connector 161b-2. To this end, the fixed connector 161b-1 and the mating connector 161b-2 should be fixed to face the rear cover 123 and the rim frame 121, respectively.

The light emitting type indicator according to an embodiment of the present invention may further include a lighting guide for guiding the illumination light emitted from the LED lamp 131 of the lamp module 130 to the cover panel 110. The lighting guide may include, for example, a perforation holder 100a, an optical fiber 100b, and an optical fiber sleeve 100c as shown in FIG.

The perforation holder 100a is formed on the front surface of the cover panel 110 as shown in FIG. The perforation holder 100a is composed of a plurality as shown. The perforation holder 100a may be provided on the cover panel 110 along the road information eye symbol provided on the cover panel 110. [

As shown in FIG. 1, the optical fiber 100b is inserted and fixed in a state of passing through the perforation holder 100a. The other end of the optical fiber 100b extends to the rear of the cover panel 110 and is inserted into the optical fiber sleeve 100c, . At this time, the optical fibers 100b are composed of a plurality of optical fibers 100b, one end of which is inserted into each of the plurality of perforation holders 100a, and the other end of which is formed in the form of a bundle, and is inserted into an optical fiber sleeve 100c described later. The optical fiber 100b can be inserted into the perforation holder 100a through a socket of a bush type as shown in FIG. The optical fiber 100b guides the illumination light of the LED lamp 131 to the perforation holder 100a and emits illumination light to the surface of the cover panel 110. [

As shown in FIG. 1, the optical fiber sleeve 100c has a plurality of optical fibers 100b inserted therein and fixed thereto by adhesive, and the lamp module 130 is mounted on the other side by adhesion or bolting. The optical fiber sleeve 100c guides the illumination light emitted from the LED lamp 131 of the lamp module 130 to the optical fiber 100b.

Here, the optical fiber sleeve 100c may be configured such that the lamp module 130 and the optical fiber 100b are easily assembled and screwed into a pair of hollow tubes as shown in FIG. In this case, the optical fiber sleeve 100c is integrally formed by screwing the optical fiber 100b having a bundle in one of the pair and the lamp module 130 installed in the other, so that the optical fiber 100b and the lamp The module 130 can be easily mounted.

Meanwhile, the light-emitting type indicator according to the embodiment of the present invention may further include an illuminance sensor for providing external illuminance of the case 120 as shown in FIG. The illuminance sensor is provided on the outside of the case 120 at one end to measure the illuminance of the outside of the case 120. The illuminance sensor transmits the measured illuminance value to the lamp driving module 150 described above. Accordingly, the driving unit 157 of the lamp driving module 150 generates a driving signal for driving the switching unit 153 according to the illuminance value of the illuminance sensor. For example, when the illuminance value of the illuminance sensor corresponds to the predetermined nighttime identification value, the driving unit 157 applies a driving signal for turning on the LED lamp 131 to the switching unit 153, And applies a drive signal for turning off the LED lamp 131 to the switching unit 153 when the predetermined daytime identification value is satisfied. Accordingly, the LED lamp 131 can be lit only at night.

Here, the lamp driving module 150 can always turn on the LED lamp 131 during a day or night mist or raining in the manner described above by the illuminance sensor and the sensor 161 described above.

The substrate storage box 170 is embedded with the drive module substrate 159 and the detection module substrate 167 in a stacked state as shown in FIG.

The insulating material 171 is sandwiched between the driving module substrate 159 and the sensing module substrate 167 to insulate the driving module substrate 159 and the sensing module substrate 167 as shown in FIG. That is, the insulating material 171 is disposed between the substrates 159 and 167 as shown in FIG. 4, and covers the substrates 159 and 167 while shielding the opposing surfaces of the facing substrates 159 and 167 Isolation is made. The insulating material 171 is made of a soft, nonconductive material such as rubber or sponge.

The filler 172 may be composed of, for example, silicone or urethane which is phase-changed from a liquid phase to a solid phase. The filler 172 is filled in the substrate storage box 170 as shown in FIG. 4 to integrally fix the driving module substrate 159, the sensing module substrate 167, and the insulating material 171. Accordingly, the driving module substrate 159, the sensing module substrate 167, and the insulating material 171 are stably fixed in the substrate holder 170.

The operation of the humidity-responsive light-emitting type indicator capable of automatically operating upon occurrence of fog according to an embodiment of the present invention will now be described.

The sensor 161 senses the humidity and the temperature and humidity of the outside of the case 120 as shown in FIG. 1, and controls the comparator 163 described above through the interface 165 as shown in FIG. 3 . The comparator 163 outputs the above-mentioned "confirmation signal" or the above-mentioned "drive signal" to the lamp driving module 150 . At this time, the comparison unit 163 applies the signal to the communication unit 157 of the lamp driving module 150 described above. Accordingly, the lamp driving module 150 turns on the LED lamp 131 of the lamp module 130 by switching the switching unit 153 as described above. Accordingly, the LED lamp 131 illuminates the cover panel 110 through the illumination light, thereby improving the visibility of the road information sign displayed on the cover panel 110. [

However, the comparator 163 applies a signal to the lamp driving module 150 to turn off the LED lamp 131 when it is determined that the sensing value applied from the sensor 161 is not mist or rain. Accordingly, the lamp driving module 150 operates the switching unit 153 again to turn off the LED lamp 131.

Meanwhile, the sleeve 100c guides the illumination light of the LED lamp 131 to the optical fiber 100b as shown in FIG. The optical fiber 100b diverges the illumination light of the LED lamp 131 to the outside of the cover panel 110 through the perforation holder 110a provided in the cover panel 110. [ Accordingly, the optical fiber 100b substantially illuminates the road information sign displayed on the cover panel 110 to improve the visibility.

1, the cover 120 is fixed to the fitting groove 121a of the frame 121 by being inserted into the fitting groove 121a of the frame 121, Since the cover 123 is supported and fixed, it is easily manufactured.
