Description

FIELD OF THE INVENTION [0001] The present invention relates to a phosphorescent labeling apparatus and a control method thereof.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a phosphorescence labeling apparatus, and more particularly, to a phosphorescent labeling apparatus having good night vision and energy efficiency and a control method thereof.

Currently, various kinds of guide markers are sold. For example, various guide marking devices such as evacuation signboards and traffic signs are being developed and marketed.

In the case of a traffic sign, it includes a support fixed to the road surface and a metal plate installed at the upper end of the support. The metal plate is formed with letters or figures formed by painting with a highly reflective paint or bonding the reflection paper.

 The characters or graphics displayed on the traffic signs are easy to identify during the daytime, but can only be identified by the driver until the headlights of the vehicle are illuminated by the traffic signs and then scattered by the paints and reflectors. Therefore, it is difficult for the driver to confirm the displayed information before the light is irradiated, and the time for confirming and recognizing the contents is longer than the week, thereby increasing the risk of traffic accidents.

In addition, it is often the case that the light of various road vehicle headlamps does not touch the signboard. Even if the headlight light is illuminated on the signboard, it is difficult to confirm the vehicle speed and distance. The problem is likely to occur.

In order to solve such a problem, a method of installing a separate illumination source for illuminating a sign on a sign may be used. However, the conventional sign has a problem of increase in durability and maintenance cost, It is a fact that exists.

The horizontal bracket 157 is disposed on one side of the edge of the support body 156 and the vertical bracket 158 is disposed perpendicularly to the horizontal bracket 157 on the other side of the edge of the support body 156. [ The inclined bracket 159 is disposed on the other side of the edge of the support body 156 so as to intersect the horizontal bracket 157 and the vertical bracket 158 at an acute angle, respectively. The inclined bracket 159 contacts the back surface of the solar cell panel 152 to support the solar cell panel 152. The horizontal bracket 157, the vertical bracket 158, and the inclined bracket 159 are formed with a bracket through-hole 160. The bracket through-hole 160 may be used to fix the solar cell support 155 to another fixture, or to couple the solar cell support 155 and the solar cell panel 152 together.

The solar cell support 155 is installed so that the horizontal bracket 157 is disposed horizontally with respect to the ground and the inclined bracket 159 is coupled with the solar cell panel 152 to support the solar cell panel 152 at an angle . That is, the solar cell support 155 can support the solar panel 152 so that the solar panel 152 can receive more sunlight smoothly.

The incident illuminance sensor 164 is disposed in the middle of the light guide layer 132 and detects the illuminance of light emitted from the illumination module 138 and incident on the display module 122 and transmits the sensed signal to the controller 166 do. The installation position of the illuminance sensor 163 can be changed to various other positions that can detect the illuminance outside the housing 110 in addition to the housing front frame 111. [ The installation position of the incident light intensity sensor 164 may be changed to various other positions capable of sensing the illuminance of light emitted from the lighting module 138 in addition to the light guiding layer 132.

The control unit 166 controls the lighting module 138 according to the sensing signal of the illuminance sensor 163. Specifically, the control unit 166 receives the sensing signal from the illuminance sensor 163, applies the operation control signal to the operation unit 170 using the preset data stored in the storage unit 168, And then control the operation of the lighting module 138 by generating an output control signal. For example, in the case where the surroundings of the housing 110 such as at night become dark, the control unit 166 controls the illuminance Is detected by the illuminance sensor 163 and the reference illuminance Ipre stored in the storage unit 168 in advance If the illuminance Is detected by the illuminance sensor 163 is equal to or lower than the reference illuminance Ipre, the lighting module 138 is controlled to blink at a preset time interval (for example, at intervals of 3 seconds) Module 122 may be illuminated.

At this time, the light irradiated to the illumination module 138 is irradiated to the display layer 125 together with the light that is phosphorescent in the phosphorescent layer 124 of the display module 122, so that the display mark 126 formed on the display layer 125, Becomes a recognizable state at night. The control unit 166 receives the detection signal from the illumination sensor 163 and turns off the illumination module 138 when the illuminance Is detected by the illumination sensor 163 exceeds the reference illumination Ipre, The energy required for driving the module 138 can be saved.

The control unit 166 receives the detection signal from the incident illumination sensor 164 and detects the incident illumination Iis sensed by the incident illumination sensor 164 and the reference illumination illumination Iipre stored in the storage unit 168 in advance, . If the sensed incident illumination Iis does not reach the reference incident illumination Iipre, information on the incident illumination Iis can be transmitted to the outside through the communication unit 172, such as a management server or an administrator terminal. Therefore, the manager or operator who manages the phosphorescent marking apparatus 100 can confirm the aging of the lighting module 138 or the lifetime of the lighting module 138 through the information transmitted from the communication unit 172, It is possible to quickly replace the battery.

The output 174 may generate a light or sound notification signal via the lamp 175 or the speaker 176. The output section 174 is controlled by the control section 166. The control unit 166 can control the output unit 174 according to a signal received from an external server through the communication unit 172. [ For example, the control unit 166 may control the output unit 174 to output the output data stored in the storage unit 168 according to a signal received from the external server 10 through the communication unit 172. In another example, the control unit 166 may control the output unit 174 to output a signal received from the external server 10 through the communication unit 172 in real time. The output data stored in the storage unit 168 by the communication unit 172 communicating with the server 10 can be continuously updated. The output data through the output unit 174 may be in various forms such as a flashing pattern of the lamp 175, a notification character that can be displayed through the lamp 175, an alarm sound through the speaker 176, . The output data stored in the storage unit 168 may be updated by the user. In this case, the housing 110 may be provided with an input unit for inputting data such as a USB port.

The speaker 176 may be housed in the housing 110 or the solar cell module 150 or may be arranged to be coupled to the housing 110 or the solar cell module 150 or may be connected to the housing 110 or the solar cell module 150 Can be installed separately.

The communication unit 172 has a function of receiving a radio broadcast signal in addition to the function of communicating with the server 10, and it is also possible to output a radio broadcast through the output unit 174. [ That is, according to the signal of the server 10, the communication unit 172 receives the radio broadcast signal transmitted from the radio transmission station 20, and the control unit 166 outputs the radio broadcast signal received through the communication unit 172 The speaker 176 can be controlled. In this case, it is possible to transmit disaster broadcasts via radio broadcasting to people in real time.

The output unit 174 may be implemented with various structures that can generate various types of notification signals that people can recognize, in addition to the structure including the lamp 175 and the speaker 176. [ As another example, the lighting module 138 may function as an output 174 that generates a notification signal with light.

In addition, the phosphorescent marker 100 according to an embodiment of the present invention includes a sealing member 174 disposed inside the housing 110. The sealing member 174 blocks a gap between the housing front frame 111 and the housing rear frame 115 to prevent moisture or foreign matter from flowing into the housing 110. Although a pair of sealing members 174 are shown on both sides of the lighting module 138 in the figure, the number and position of the sealing members 174 can be variously changed.

Hereinafter, a control method of the phosphorescent marker 100 according to an embodiment of the present invention will be described with reference to FIG.

First, in the providing step S10, a phosphorescent marker 100 as described above is provided where it is needed.

After the phosphorescent marker 100 is installed, the illuminance sensor 163 senses the illuminance outside the housing 110 (S11). At this stage, the detection signal of the illuminance sensor 163 is transmitted to the control unit 166. [

The control unit 166 compares the sensed illuminance Is with a preset reference illuminance Ipre after receiving the sensing signal of the illuminance sensor 163 (S12).

At this time, when the illuminance Is detected by the illuminance sensor 163 is equal to or lower than the reference illuminance Ipre, the control unit 166 controls the lighting module 138 to blink (S13). The light emitted to the illumination module 138 is irradiated to the display layer 125 along with the light that is phosphorescent in the phosphorescent layer 124 of the display module 122, Night visibility is improved.

On the other hand, if the illuminance Is detected by the illuminance sensor 163 exceeds the reference illuminance Ipre, the control unit 166 maintains the illumination module 138 in the OFF state (S14).

When the lighting module 138 is controlled to be flickered, the controller 166 limits the operation of the lighting module 138 for a long time, thereby preventing the lighting module 138 from overheating and reducing energy consumption. That is, the control unit 166 increments the number of blinks of the lighting module 138 (S15), compares the counted number of blinks M with a predetermined reference number of blinks Ms (S16) ) Is greater than or equal to the reference number of blinks (Ms), steps after the sensing step S11 by the illuminance sensor 163 are repeated. If it is determined that the illuminance Is detected by the illuminance sensor 163 exceeds the reference illuminance Ipre, the illumination module 138 is turned off.

The phosphorescent marker 100 according to the present invention may be controlled in accordance with the electric signal of the solar cell module 150 by the lighting module 138. The concrete control method thereof is as shown in Fig.

Referring to FIG. 7, first, in the providing step S10, a phosphorescent marker 100 as described above is provided where it is needed.

After the photoluminescent marking apparatus 100 is installed, as the solar cell module 150 operates, electricity generated from the solar cell panel 152 is supplied to the power supply unit 146. At this time, the control unit 166 senses the electric signal Es of the electric signal of the solar panel 152 (S21), and outputs the electric signal Es of the solar panel 152 and the predetermined reference electric signal Epre, (S22). The predetermined reference electrical signal Epre may be stored in the storage unit 168. [ The electric signal Es of the solar panel 152 may be a current value or a voltage value of the electricity produced by the solar panel 152. [ Therefore, the electric signal Es of the solar panel 152 is proportional to the intensity of the sunlight irradiated to the solar panel 152. [ The reference electrical signal Epre is supplied to the phosphorescent marking apparatus 100 such that the periphery of the phosphorescent marking apparatus 100 is bright enough to confirm the display layer 125 without any illumination, 100 can be set to an appropriate size to distinguish when the surroundings are dark. The intensity of sunlight may vary during the sunrise depending on the installation position of the phosphorescent marker 100 so that the electric signal Es of the solar panel 152 is continuously stored in the storage unit 168, It is possible to set an appropriate reference electrical signal Epre according to the installation position using the accumulation data.

When the electric signal Es of the solar panel 152 is equal to or lower than the reference electric signal Epre, the control unit 166 activates the lighting module 138 (S23). The light irradiated to the illumination module 138 is irradiated to the display layer 125 along with the light that has been phosphorescent in the phosphorescent layer 124 of the display module 122, Night visibility is improved.

On the other hand, if the electric signal Es of the solar panel 152 exceeds the reference electric signal Epre, the control unit 166 maintains the lighting module 138 in the OFF state (S24).

The electric signal Es of the solar cell panel 152 can be maintained at a low level even if the blade is blurred even during the daytime. However, even if the solar cell panel 152 is broken, The signal Epre can be maintained at a lower level. Therefore, it is necessary to check whether the solar cell panel 152 is malfunctioning when the operating time To of the lighting module 138 becomes excessively long.

To this end, the control unit 166 determines that the operating time To of the lighting module 138 exceeds the predetermined reference operating time Tpre (S24) while the lighting module 138 is operating, . When the operation time To of the illumination module 138 exceeds the predetermined reference operation time Tpre, the control unit 166 receives the detection signal from the illumination sensor 163, The illuminance Is is compared with the illuminance (IE) by the electric signal of the solar panel 152 (S25). At this time, if the illuminance (IE) by the electric signal of the solar panel 152 is not a value corresponding to the illuminance Is sensed by the illuminance sensor 163, the control unit 166 generates a failure signal, 172 to the outside (S26), or generate a notification signal through the output unit 174. [

As described above, the phosphorescent marker 100 according to an embodiment of the present invention includes a phosphorescent layer 124 in which the display module 122 can phosphoresce light so that when the ambient environment is dark, the light source 140 Is lighted in the phosphorescent layer 124 and light phosphorescent in the phosphorescent layer 124 is irradiated to the display layer 125 to improve the visibility of the display layer 125 in a dark environment.

The phosphorescent marker 100 according to an embodiment of the present invention may be configured such that the phosphorescence layer 124 phosphoresces the light emitted from the illumination module 138 to the display layer 125, A good lighting effect can be obtained even if the time is reduced.

Further, the phosphorescent marker 100 according to an embodiment of the present invention can exert a good lighting effect while controlling the flashing of the lighting module 138, thereby reducing energy consumption and maintenance cost.

Further, the phosphorescent marker 100 according to an embodiment of the present invention can self-procure the energy required to drive the illumination module 138 through the solar cell module 150, and is environmentally friendly and can be maintained at a low cost.

8 is a perspective view of a phosphorescent marker according to another embodiment of the present invention.

The photoluminescent marking apparatus 200 shown in FIG. 8 is a modification of the installation positions of the battery 147 and the control unit 166, and the battery 147 and the control unit 166 are embedded in the solar cell module 150. Such a phosphorescent marker 200 is advantageous for installation or transportation work because the weight of the assembled housing 110 is relatively light.

Although the preferred embodiments of the present invention have been described above, the scope of the present invention is not limited to those described and illustrated above.

For example, although the drawing shows that the light guide layer 132 and the base layer 130 are disposed on the rear surface of the display module 122 and the protection layer 136 is disposed on the front surface of the display module 122, The display module 122 can be changed to another structure, and other layers disposed before and after the display module 122 can be optionally omitted.

Also, the power supply unit 146 may supply power to the lighting module 138, such as a storage battery that is supplied with electricity from the solar cell module 150, a structure including a replaceable battery, or a structure that operates by receiving external power directly But may be varied in various other forms that can be supplied.

Although the light source assembly 139 of the lighting module 138 is shown as being disposed in the form of a round light circle outside the edge of the light guide layer 132, the shape and location of the light source assembly or the lighting module including the light source assembly may vary .

Further, the structure of the heat sink 143 provided in the lighting module 138 may be variously changed. For example, Figs. 9 and 10 show various modifications of the heat sink provided in the lighting module.

9 includes a heat sink body 251 coupled to the light source assembly 139 and a heat sink support rib 256 for supporting the light guide layer 132. [ The heat sink body 251 includes a heat sink accommodating groove 252 in which the light source assembly 139 is accommodated and a heat sink opening 252 connected to the heat sink accommodating groove 252 to emit light generated in the light source 140. [ And a heat sink retaining jaw 254 which is in contact with an end of the light guiding layer 132. The heat sink support ribs 256 protrude from the heat sink body 251 such that the pair of heat sink support ribs 256 face each other with the heat sink openings 253 therebetween. The pair of heat sink support ribs 256 contact the both side surfaces of the light guide layer 132, respectively. Such a heat sink 250 is configured such that the heat sink retaining jaw 254 contacts the end of the light guide layer 132 and the pair of heat sink support ribs 256 contact the both side surfaces of the light guide layer 132, 132 in a non-moving manner. Therefore, the light guiding layer 132 and the display module 122, the protective layer 136, and the base layer 130, which are directly or indirectly coupled to the light guiding layer 132, can be stably and stably fixed inside the housing 110 .

The heat sink 260 shown in Fig. 10 further includes a heat sink reinforcing rib 261 as compared with the heat sink 250 shown in Fig. A plurality of heat sink reinforcing ribs 261 are spaced apart from each other in the longitudinal direction of the heat sink body 251 between the pair of heat sink supporting ribs 256. The plurality of heat sink reinforcing ribs 261 serve to reinforce the overall strength of the heat sink 260 so that the heat sink 260 can more stably support the light guide layer 132. [

The heat sinks 250 and 260 may contact and support at least a part of the display module 122 in addition to the light guide layer 132. [

Although the preferred embodiments of the present invention have been described above, the scope of the present invention is not limited to those described and illustrated above.

For example, although the phosphorescent marker 100 according to the present invention includes the illuminance sensor 163 for sensing the illuminance outside the housing 110, the illuminance sensor 163 may be omitted. That is, the solar panel 152 may perform the role of the illuminance sensor 163. In this case, the control unit 166 can operate the lighting module 138 in accordance with an electric signal generated in the solar cell panel 152.
