Description

{Walk Guide System for Trail}

The present invention controls the brightness of illumination to vehicles and pedestrians in areas where vehicles or pedestrians can pass such as roads, sidewalks, tunnels, parking lots, inside buildings, walkways, etc., or controls the entire lighting system through power line communication from a central server And more particularly to a smart lighting system based on a power grid communication lighting control capable of interlocking control with external devices.

Roads, sidewalks, tunnels, parking lots, inside buildings, and walkways are guided by street lights or lights at regular intervals to guide pedestrians and vehicles. In recent years, a configuration has been proposed in which illumination systems are controlled in various ways such as applying emotional illumination to a walkway or adjusting the brightness of a tunnel interior.

In addition, a control method using a power line communication for remotely controlling a plurality of devices provided in a home, an office, a factory, or the like has been widely used recently due to its convenience. Power line communication uses a power line as a communication line. In general, 60Hz AC power or DC power is transmitted by transmitting data from several tens of hz to several megahertz frequency, and communication signals of received data are separated, transmitted and received . As for the configuration for controlling the lighting devices using the power line communication, many prior arts have been filed since the development of the technology. However, most of them are limited to the method of improving the efficiency of the power line communication itself or limited to the lighting control, It can be seen that there is a tendency to be somewhat insufficient for interlocking control with peripherals to be further considered.

In order to solve such a problem, Korean Patent Laid-Open No. 10-2016-0100637 discloses a power line communication method for dimming control of an illumination device and a lighting system.

Specifically, a power line communication method for dimming controlling an illumination apparatus according to a ratio of a time when a voltage is modulated is proposed.

However, this communication method only refers to the elements that affect the control method between the lighting apparatuses, but does not refer to a configuration for real-time interlocking control in cooperation with a device other than the lighting device. There is a disadvantage in that it can not provide a configuration that can be used.

As another prior art, Korean Patent No. 10-1736766 discloses an LED dimmer self dimming device.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The accompanying drawings are not drawn to scale and wherein like reference numerals in the various drawings refer to like elements.

FIG. 1 is a conceptual diagram showing a basic concept of a smart lighting system based on a power grid communication lighting control of the present invention, FIG. 2 is a basic embodiment of a smart lighting system based on a power grid communication lighting control of the present invention, FIG. 3 is a conceptual diagram showing a basic configuration of a smart lighting system based on a power grid communication lighting control of the present invention.

1 to 3, a basic configuration of a smart lighting system based on a power control communication lighting control system will be described. The lighting system is controlled by utilizing a power grid provided in an installation area, and includes a PLC (Power Line Communication A router 200 for transmitting a control signal to a plurality of lighting apparatuses 100 electrically connected to a power network through a central control server 300 and a central control server 300 for transmitting control signals to the router 200 , And a plurality of lighting apparatuses (100) installed at regular intervals along an installation area in a state of being electrically connected to a power network.

In more detail, the installation area herein refers to a transportation means such as a road, a walkway, a park, a walkway, a parking lot, a building interior, a bicycle road, a tunnel, This installation area must be equipped with a power network to supply power from an external power source.

It is necessary to solve the cause of the communication error in such a power network because the communication signal becomes weaker as the extended length becomes longer. Accordingly, it is possible to confirm whether or not the communication can be performed by sequentially transmitting the communication signals sequentially in the order close to the router 200 that is designated or separately installed according to the signal operation, and it is also possible to confirm the location where the communication is impossible. 100 may be provided with a function of also serving as a data repeater to assist the signal transmission through the illumination device 100. [

Further, the power network is provided with a plurality of lighting apparatuses 100 that receive power and irradiate light, a router 200 connected to the power network and providing a control signal to the lighting apparatus 100 through a power network, The central control server 300 is configured to generate control signals to be transmitted and to substantially control the lighting apparatus 100. [ It is most preferable that the central control server 300 is located in an installation area. However, when a module having a remote communication function such as LTE is further installed in the router 200, control or monitoring can be performed through a remote terminal or the like Therefore, if such a configuration is provided, it is not necessarily necessary to be located in the installation area.

That is, the central control server 300 is connected directly or indirectly to the router 200, and the router 200 can controllably control the plurality of lighting devices 100, 100 to provide a control signal provided from the central control server 300 to the lighting apparatus 100. [

Alternatively, it may be configured to receive the detection signal from the emergency bell or various sensors located in the space in the input terminal of the illumination device 100, and to send the signal directly to the central control server 300 . Further, if such a function is further expanded, it is operated as a beacon so that it is interlocked with a mechanical device capable of communicating with a nearby mobile phone, and receives the position, transmits the position to the central control server 300, It is also possible to utilize structural roads in case of identification or dangerous situation.

Here, the characteristic part is to transmit the signal through a power network provided in the installation area, without any additional communication line. This means that we can receive a voltage of 220V AC or DC as a commercial power supply, Various commercial frequencies are available. Therefore, if the signal is transmitted at the same frequency as the commercial frequency, the signal will be canceled by the frequency of the commercial power supply. However, if the signal is transmitted at a different frequency, the signal can be transmitted along the power network It is to utilize the principle.

To this end, the router 200 is provided with a frequency database 210 in which a frequency table that can be transmitted through the power network is stored, a frequency measuring unit 220 for measuring a frequency of a power source supplied through the power network, The configuration of the signal frequency application unit 230 that modulates a frequency stored in the database 210 to a frequency other than the frequency measured by the frequency measurement unit 220 and transmits the modulated frequency to the illumination device 100 through the power network . In other words, various frequency tables are stored in the frequency database 210, and the frequency of the power supplied through the power network (and frequency of the transmitted signals) is measured, and the control signal is modulated at a frequency other than the measured frequency and transmitted The respective signals can be transmitted without being interfered with each other.

This power line communication (PLC) can be easily installed because it can communicate using the power network provided for power supply as it is, and if it can avoid frequency interference efficiently, it is possible to reduce the installation cost It is a requirement.

Furthermore, the central control server 300 may further include a communication frequency assigning module 310 for assigning different frequency values to the illumination apparatuses 100. This configuration further reinforces the above-mentioned configuration. When a signal is transmitted from each illumination device 100 by assigning a frequency to each illumination device 100, the respective signals are transmitted at different frequencies to minimize the interference .

Thereafter, the lighting device 100 also performs lighting control through the received control signal, generates a feedback signal including whether to perform the lighting control, and outputs the feedback signal at a frequency given through the communication frequency application module 310 And a controller 110 for transmitting to the central control server 300 through the power network. Accordingly, it is possible to determine whether the control signal is received by receiving the feedback signal from the central control server 300, so that an efficient communication network can be constructed with only the power line.

Here, an example of lighting control of the lighting apparatus 100 will be described as follows.

First, as shown in FIG. 1, in the same configuration as the tunnel, lighting control of the lighting apparatus 100 is possible according to the entry of a vehicle and the movement of the vehicle. For example, when the vehicle is approaching, the direction of travel of the vehicle is grasped to illuminate a light within a certain range in the corresponding direction, and the lighting device 100 mounted at a position where the vehicle passes is turned off after a predetermined time. In this case, the configuration of the LED 131 in the illumination device 100 may be divided into a plurality of colors. For example, if the LED 131 on the left side is green, the right side is green, and the upper and lower sides are yellow, a green light in a specific direction is turned on or a yellow light is turned on Further, when the lighting apparatus 100 is attached to a ceiling or a floor without attaching the lighting apparatus 100 to the wall, it is also possible to provide a yellow light or the like as a center lane. In addition, since various controls such as individual flicker control or sequential flicker control are possible, it can be said that the utilization range as a guide role is very wide if such control method is utilized.

As another example, similar to the outdoor walkway as shown in FIG. 2, the control similar to that of FIG. 1 is possible.

In addition, in order to guide the walking direction in the room, the lighting device 100 may be used, and the lighting may be controlled by recognizing a pedestrian or a book cart. Alternatively, The present invention is applicable to a variety of situations in which illumination and guidance are required, such as when guiding the direction of rotation in a rotary intersection or the like.

The detailed configuration and description of the illumination device 100 will be described in more detail below. First, the configurations that can be further included in the smart illumination system will be described.

4 is an exploded perspective view showing a detailed configuration of the illumination device 100 of the present invention.

First, the lighting apparatus 100 is installed at regular intervals along an installation area, and includes a case 120 having an upper opening opened and having an accommodation space 121 therein, a substrate 120 installed in the accommodation space 121, (130). The substrate 130 may have the following configuration in detail. An LED 131 or other illumination device mounted along the circumference of the substrate 130 may be used as the LED 131. The LED 131 may be representative of the LED 131, do.

Each of the LEDs 131 is mounted along the circumference of the substrate 130 at regular intervals or a group of LEDs 131 in which several LEDs 131 are bundled together at regular intervals along the circumference of the substrate 130 . Of course, the LEDs 131 are supplied with power through the substrate 130, and all of the substrates 130 are electrically connected to the power grid, so that power supply and communication are possible.

At this time, a central portion of the substrate 130 becomes empty. On the central portion, a controller 110 for receiving control signals transmitted through a power network and controlling driving of the LEDs 131 according to the received control signals, A control unit with a built-in controller is located. Furthermore, since the upper portion of the case 120 in which the substrate 130 is embedded is opened, it is possible to prevent rainwater, snow, frost, moisture, Dust, insects, and the like. Therefore, in order to solve such a problem, a cover 140 that can cover the open side is further provided.

The cover 140 may be formed of a transparent material so that the light emitted from the LED 131 is emitted to the outside. In this case, the LED 131 is applied only around the substrate 130, It is necessary to increase the light amount of the light sources 131 and 131. In addition, since the LED 131 emits light having a directivity, it is more efficient to configure the LED 131 to emit light only at the peripheral portion without using the central portion where the LED 131 is not located. The LED 131 may further include a display window 144 for exposing light of the LED 131 to the outside at a position corresponding to the LED 131. The light emitted from the LED 131 may be emitted through the display window 144, It is possible to have a structure that can increase. In addition, it is needless to say that the central portion may serve as a heat sink for the heat of the LED 131 and the substrate 130 to escape to the outside.

That is, this configuration is referred to as an illumination device 100 provided with a plurality of LEDs 131 at regular intervals along the circumference of the housing. The configuration of such an illumination device 100 is that when the straightness of the LED 131 is considered , It is more likely to be irradiated in various directions of illumination substantially than in the case of arranging a plurality of LEDs 131 at the central portion and injecting a reflection angle. Accordingly, by arranging the LEDs 131 along the periphery of the illumination device 100 and arranging the reflector 164 for each of the LEDs 131 or having a different reflection configuration or slope, a much smaller number of LEDs 131 and a lower Even if the LED 131 having a light amount is used, the illumination efficiency proportional to the illumination device 100 formed by driving the LED 131 at the center can be expected. Furthermore, since it is possible to selectively turn off and on the LED 131 located in a specific circumferential direction according to need, various configurations utilizing the LED 131 can be considered.

Next, the smart lighting system may further include an external device 700 mounted on the periphery of the lighting device 100 via a power network as shown in FIG. Here, the external device 700 can be understood as a configuration including any one of a display device, a speaker, and a timer for displaying an image. The central control server 300 further includes a configuration of the external device control module 330 so as to control the driving of the external device 700 so that the external devices 700 connected to the lighting device 100, So that it is possible to perform a complex control such as visual guidance through a display device, audible guidance through a speaker, flicker control through a timer, or dimming control.

Further, in the case of a large building or an underground tunnel as an IoT control similar configuration, each lighting apparatus 100 may further have a calling function in which a unique number is embedded. That is, the illumination device 100 is also provided with such a configuration capable of recognizing and communicating. In this case, when the specific key input or motion (for example, waving) The external device illumination device 100 recognizes this and can be provided with a function of automatically transmitting a location to a central control server 300 or a related fire or police station, to be.

As shown in FIG. 3, even if there is no such complicated control structure, the illumination device 100 may further include a light sensing sensor for sensing the ambient illuminance to detect the illuminance around the illuminating device 100. In this case, The light intensity of the light emitted from the illumination device 100 may be controlled by controlling the light intensity of the LED 131 according to the brightness of the light sensed by the light sensor. And can be configured to control the illuminance. For example, the illuminance of the light emitted from the LED 131 is reduced in the nighttime when the ambient illuminance is lowered, and the illuminance of the light emitted from the LED 131 is increased during the daytime when the ambient illuminance is increased. It goes without saying that such a configuration is also applicable to the dimming control for preventing the driver's glare passing through the tunnel when the lighting apparatus 100 is provided in a tunnel or the like.

Furthermore, it is possible to further include a speaker (not shown) that outputs sound to the lighting apparatus 100 itself and a noise detection sensor (not shown) that detects ambient sound. Since the illumination device 100 includes a substrate 130 configured to receive power and control a signal to control the LED 131 inside the substrate 130, It is of course possible to attach the speaker and the noise sensor directly to the lighting device 100 in a state where the speaker and the noise sensor are directly connected to the board 130 or in a state where the speaker and the noise sensor are electrically connected to the board 130.

When the configuration of such a speaker is added, the central control server 300 controls the speaker as follows. The central control server 300 includes a sound database (not shown) storing a sound to be output from the speaker and a sound database And a sound control module (not shown) for changing the volume of the sound to be output from the speaker.

Here, the sound database may include, for example, a guidance voice or music. In this case, the level of the volume detected by the noise detection sensor may be referred to as the noise level around the lighting apparatus 100. Accordingly, when the detected volume is large, the volume is raised to provide sound, and when the detected volume is small May provide the volume without needing to grow it, or it may provide the volume lower than the original.

5 is a perspective view and a cross-sectional view showing an embodiment of the lighting apparatus 100 of the present invention.

Now, the detailed configuration of the lighting apparatus 100 will be described in detail as follows.

The case 120 or the cover 140 that has appeared in the foregoing description should be made of a material having sufficient strength and durability to protect the substrate 130 built therein. It is a basic structure that the cross section has a rectangular shape or a shape in which the corner portions are formed in a curved shape, which is the most stable form. It is needless to say that various forms can be applied as needed.

Referring to FIGS. 4 and 5A, the case 120 is formed with an opening having an open top, and includes a receiving space 121 therein. The case 120 may include a light transmitting material, a diffusion material or a light impermeable material Can be selectively applied. Here, the depth of the accommodating space 121 is preferably about 1 to 2 cm, but it can also be adjusted as needed. The controller 121 includes a controller 110 having a built-in controller 110 (which may further include a power module 132 that is supplied with electric power through a power grid), a substrate 130 on which the LED 131 is mounted ).

The fixing part 123 may further include a groove 123 formed on a side surface of the case 120. The fixing part 123 may protrude from the side surface of the case 120 as shown in the figure. A separate groove is formed in the fixing part 123 so that the fixing part 123 is brought into close contact with the part where the lighting device 100 is to be mounted and then a separate fixing fastener 124 is inserted into the groove and tightened But it is needless to say that it is possible to further include a configuration in which the lighting apparatus 100 can be fixed everywhere.

Further, the cover 140 may be formed of a light-impermeable material to cover the entrance of the case 120, and the light of the LED 131 may be exposed to the outside at a position corresponding to the LED 131 A display window 144 of a light-transmitting material is provided. The display window 144 preferably has a recess 140 formed at a position corresponding to the LED 131 on the periphery of the cover 140 and mounting the display window 144 thereon .

At this time, the cover 140 may further include a curved surface portion 142 that is rounded from a portion of the upper surface toward a portion of the side surface so as to have an apparently stable shape. The formation of the curved surface portion 142 means that the cover 140 can be formed with a certain height. If the cover 140 has such a shape, the display window 144 positioned on the curved surface portion 142 may be further provided with a curved surface display portion 145 that is rounded by exposing the curved portion 142 to the outside with the same curvature as the curved portion 142 Of course. As a result, it is possible to easily remove the foreign substance such as dust when the foreign substance is adhered to the outside, and also to make the light irradiation range of the LED 131 having the straightness to be widened through the curved surface display part 145 Reflection) can of course be provided.

Such a curved surface may allow a vehicle or the like to easily pass over the lighting apparatus 100 when the lighting apparatus 100 is mounted on a floor surface, It is possible to provide a role of weakening the latching jaw so as not to wear it.

When these structures are assembled, they have the appearance as shown in FIG. 5 (a).

5 (b), the inner surface of the cover 140 is connected to the peripheral portion of the substrate 130 on which the LED 131 is mounted, the controller 110 (and the power module 132) May be further included in the partition wall 143. The partition wall 143 may be formed of a metal or the like. The separation barrier ribs 143 are formed on the substrate 130 so as to press the non-critical boundary portions of the substrate 130 through the separation barrier ribs 143, It is possible to prevent the heat generated from the LED 131 through the respective partition walls 143 from affecting the controller 110 and at the same time the light emitted from the LED 131 It is possible to provide various functions such that the light can be emitted only toward the curved surface display part 145 without flowing into the interior of the lighting device 100. [ At this time, the controller 110 located inside may not form the partition wall 143 too strictly so that the heat can be discharged to the outside, but the partition wall 143 may be formed by drilling a hole (not shown) It is needless to say that the hole may be formed.

6 is a partial perspective view showing an embodiment in which the dust removing structure is applied to the illumination device 100 of the present invention.

Hereinafter, a configuration for interlocking with an external device in a smart lighting system for a while will be described first.

First of all, as mentioned in the foregoing description, the smart lighting system is not limited to a wide range of mounting locations, but in the case where the smart lighting system is installed inside the tunnel, the following matters may be further considered.

First, the external device 700 may be a ventilator provided inside the tunnel, and the illumination device 100 may also include a gas sensor (not shown) for sensing the concentration of gas in the tunnel, 101 may be further included. In other words, the gas sensor 101 has a sensing part exposed to the outside, and it measures the concentration of combustion oxide and dust generated when the vehicle is driven in the tunnel, and when the measured value becomes higher than the specified amount or ratio And the ventilator provided in the tunnel is driven. The control module 330 of the external device 700 of the central control server 300 receives the configuration of the fan control unit 331 for controlling the operation of the fan according to the gas concentration measured by the gas sensor 101 and the degree of dust generation It is of course possible to provide a configuration in which the internal environment of the tunnel and the ventilator are driven in conjunction with each other.

However, even if ventilation is carried out in this way, burning oxides, dust, etc. are continuously accumulated on the surface (preferably the surface of the cover 140) of the lighting apparatus 100. Such accumulation may not only reduce the efficiency of the sensors provided in the illumination device 100 but also cause a phenomenon in which the light emitted from the LED 131 is blocked by the dust and gradually becomes darker than in the initial setting. However, in order to wipe the surface of the lighting device 100 every time, the position where the lighting device 100 is mounted is somewhat far away from the position for manual cleaning by a person, which makes cleaning difficult.

A plurality of electrostatic plates 501 formed on the outer surface of the display window 144 at regular intervals and formed between the electrostatic plate 501 and the electrostatic panel 501 are formed on the outer surface of the display window 144, And an induction electrode 502 for generating an electric field by alternately applying an alternating voltage to the electrostatic plate 501 so that dust located around the electrostatic plate 501 is charged through the electric field to have an electrostatic force. Here, the induction electrode 502 is an electrode capable of generating a kind of plasma. The more the induction electrode 502 is provided, the better the electric field can be generated. When one induction electrode 502 generates an alternating current voltage, the other induction electrode 502 is grounded, or the induction electrode 502 is grounded or several induction electrodes 502, A method of grouping the groups 502 and driving them in the group order can be utilized.

At this time, the electrostatic plate 501 is made of an alloy of a metal or a non-metal or the like and made of a conductive material such as copper so as to provide transparency to the metal such as copper. Means a configuration in which an AC voltage can be applied in a state in which it does not disturb the irradiation to the outside. In this case, the smaller the gap between the electrostatic plates 501 is, the better.

Further, when an AC voltage is applied through the induction electrode 502, an electric field is generated. At this time, the dust is charged under the influence of the electric field. However, since the voltage that is continuously applied varies as the AC voltage is applied, the charged dust is repeatedly influenced by the attractive force and the repulsive force according to the change (electric field) of the voltage, and the dust is moved in a specific direction . Accordingly, such a configuration has a configuration that can remove the dust even if the dust collecting process is eliminated by using a kind of electrophoretic power to go one step further than the electrostatic dust collecting method of the conventional dust collecting structure.

The central control server 300 may further include the configuration of the electrode control module 340 that controls the driving of the induction electrode 502 according to the gas concentration measured by the gas sensor 101 and the amount of dust generated, And the dust or the like is removed by flowing the alternating voltage sequentially or sequentially in the groups or the groups designated by the induction electrode 502 after the abnormal amount or the dust generation amount exceeds the specific amount.

Furthermore, when dust is blown off only by such electrophoretic force, a voltage of about 20 kV is needed instantaneously even if a small amount of current flows. If such a work is continued for a long time, the required amount of electric power will naturally increase. However, it may happen that the material is melted and adhered to the surface by heat due to the characteristics of dust, so that it may be very ineffective when merely dissolving the pressed portion by the electrophoretic force and removing the dust. The fan 504 may further include a fan 504 installed inside the housing of the lighting device 100 to generate wind toward the surface of the dust collecting module. A plurality of ventilation holes 503 penetrating the surface of the display window 144 (preferably also in the housing) may be further formed so as to be diverted to the outside of the display windows 144. Since the vent hole 503 does not have to be large enough to be seen and only a small amount of ventilation holes 503 are formed though the vent hole 503 is almost invisible because the ventilation hole is small, To the surface of the substrate. Of course, if the number of spots affected by the wind increases, the efficiency of dust can be increased through the wind.

Further, in order to increase the efficiency of use of the fan 504 in the dust removal module 500, when the induction electrode 502 is driven, the fan 504 is simultaneously driven, or the induction electrode 502 is driven, The fan control unit 341 may be configured to assist the movement of the dust, such as driving the fan 504 immediately before.

The problem with this configuration is that it is a dust that does not easily fall off in ambiguous locations. That is, in the case of the peripheral region of the display window 144 (the boundary portion between the display window 144 and the housing), the region where the dust is hardly moved and accumulates due to the influence of wind blown from the static electricity plate 501 and the fan 504 May occur. Of course, there is no problem even if dust accumulates in the remaining housing portion except the display window 144. However, if dust accumulates around the display window 144, the accumulated dust collapses due to its weight or wind blows, There is a risk of screening. Accordingly, the dust-collecting pad 505 (which is formed of a material having a conductivity lower than that of the electrostatic plate 501 in this area and is blown along the wind from the display window 144 and collects dust that has not moved far away from the periphery of the display window 144, And an auxiliary electrode which is provided to be in contact with one side of the dust-collecting pad 505 so as to collect dust on the dust-collecting pad 505 by alternately applying an AC voltage lower than the induction electrode 502 to the dust-collecting pad 505 506 may be further included.

In this configuration, the dust that has not been distant from the periphery of the display window 144 is once again held, and when the wind is blown by the fan 504, the voltage supply of the auxiliary electrode 506 is released to release the dust from the dust collection state It is a configuration that allows one to be blown by the influence of the wind. Although the auxiliary electrode 506 itself is weaker than the induction electrode 502, the auxiliary electrode 506 itself is similar in structure to the dust removal module 500 and can be utilized as a dust removing structure through electrophoresis Of course it is.

In order to utilize the dust-collecting pad 505 and the auxiliary electrode 506, the central control server 300 drives the induction electrode 502 and the auxiliary electrode 506 in a manner similar to the electrode control module 340 It is needless to say that it is possible to further include the configuration of the interlocking capture control module 350 that controls the interlocking control.

In addition, the housing (preferably the cover 140) may have additional configurations that are interlocked with the internal configuration in addition to the separating partition 143 or the dust removal configuration, which is the structure of the support panel 165. [ In this case, as described above, the partition wall 143 may include a hole (not shown) or may be formed on the partition wall 143 And that the height is sufficient to provide enough space for this support panel 165 and the reflective panel to be located.

7 is a cross-sectional view showing an embodiment in which the reflection plate 164 is applied to the illumination device 100 of the present invention.

First, FIG. 7 (a) shows the inside of the cover 140 from below and FIG. 7 (b) shows from the side. 7, the support panel 165 is resiliently supported via a plurality of springs 163 attached to the inner surface of the cover 140, and the left and right portions of the support panel 165 are respectively fixed to the cover 140 Shaped support plate having a reflection surface on the opposite side of the surface on which the spring 163 is mounted so that the LED 131 is arranged in a circular arc shape, Lt; RTI ID = 0.0 > light. ≪ / RTI > The support panel 165 is attached to the inner surface of the cover 140 through the spring 163. The support panel 165 is attached to the inner surface of the cover 140 through a spring 163, U-like shape such as a horseshoe, and an area around the LED 131 is included in the area formed by bending in this manner, so that the support panel 165 surrounds the area around the LED 131, And is configured to reflect light of the LED 131.

The shape of the support panel 165 may be such that the direction in which the illumination from the LED 131 in the illumination device 100 does not need to be irradiated, So that it can be reflected to a part where irradiation amount is required. Therefore, the bent arc shape should be provided so as to have a shape corresponding to the direction in which the additional illumination is required and the direction in which the illumination is not needed further after the sufficient experiment is performed at the position where the illumination device 100 is to be installed .

Here, since the support panel 165 is mounted via the spring 163, the respective springs 163 may be provided with different elasticity, or a separate additional structure may be used to expand / contract the springs 163 Needless to say, height control is possible.

Here, the spring 163 generally keeps the designated length at the time of first mounting by hand, but it may further include a structure capable of stretching or lifting the spring 163 as required, as mentioned in the foregoing description . 7, the cover 140 includes a lifting groove 166 which is inserted inward at each position where the spring 163 is mounted and has a thread on an inner peripheral surface thereof, A lifting block 162 to which the spring 163 is fixed at an end and a lifting and lowering driving part 167 mounted on a bottom surface of the lifting groove 166 to provide a rotational force to the lifting block 162 ). ≪ / RTI >

This structure utilizes a lift block 162 that is lifted and lowered in the lift groove 166. When the lift block 162 is rotated, So that the spring 163 can be raised and lowered in the same manner. Since the elevating block 162 can not be raised or lowered naturally, it is possible to form a screw thread on the inner circumferential surface of the elevating groove 166 and also to form a screw thread on the outer circumferential surface of the elevating block 162, The elevating drive section 167 is preferably mounted on the bottom surface of the elevating groove 166 so that the elevating driving section 167 The elevating block 162 may be coupled with the elevating block 162 or may include a shaft (not shown) in the elevating driving block 167 to be coupled to the elevating block 162.

Further, in order to control the lifting drive unit 167, the central control server 300 may be controlled according to a predetermined schedule (for example, at predetermined time intervals or according to variations in sensor values received from various sensor devices) Up control module 360 for controlling the curvature of the support panel 165 by controlling the ascending and descending of the ascending and descending block 162 by driving the ascending and descending driving part 167 according to whether the light- Of course it is. Accordingly, the angle of the reflecting surface can be changed through such a configuration, so that the light irradiated from the LED 131 can be irradiated in a desired direction so that the LED 131 attached at a position that can not be used depending on the mounting position is also reflected So that the reflected light can be utilized.

In addition to the configuration of the reflector 164, the following configuration may be further included.

8 is a cross-sectional view showing an embodiment in which a moisture absorption structure is applied to the illumination device 100 of the present invention.

Since the lighting apparatus 100 is an electronic device, it is inevitably susceptible to the influence of moisture, rain, etc. in addition to dust. Thus, as shown in Figure 8 (a), the inner surface of the housing, and preferably between the inner surface of the cover 140 and the support panel 165, is coated with a water indicator that is discolored in contact with moisture A moisture absorbing structure 400 in which a color changing pad 401 and a moisture absorbing pad 402 for absorbing moisture in the air are sequentially laminated can be further provided. The moisture absorbing structure 400 includes a water absorbing pad 402 having a moisture absorbing agent such as a generally known silica gel and a coloring pad 401 having a moisture absorbing agent (indicator) such as cobalt chloride contained therein or coated on the surface thereof And its shape, thickness, weight, volume, etc. are not limited. Although the moisture absorbing pad 402 is not in the form of powder, the state of the gel, the pad, and the like can be regarded as the moisture absorbing pad 402 when the particles are aggregated into a single lump.

Here, cobalt chloride is a representative example of a moisture absorptive agent, and cobalt chloride is generally blue in color, but turns red when moisture comes in contact. Therefore, it is possible to grasp the replacement timing of the water-absorbing pad 402 through the change of the color. It is further provided with a through hole 403 through which a moisture indicator is exposed to the outside of the housing through a part of the surface to which the moisture absorption structure 400 is attached in the housing (in particular, in the cover 140) It is possible to visually confirm the color change of the discoloration pad 401 from the outside through the through hole (not shown).

Furthermore, the water-absorbing pad 402 may further include the following configuration. 8 (b), a first moisture absorption portion 404, which is composed of a hygroscopic material of a stretchable material whose volume increases by absorbing moisture in the air, and a second moisture absorption portion 404 which is formed on the outer side of the first moisture absorption portion 404 And a second moisture absorber composed of silica gel having no volume change due to moisture absorption. The two moisture absorbers may be covered by a pack or a cover 140, or may be provided with a suitable sealant as described above. However, bentonite is representative as a hygroscopic material whose volume increases by absorbing moisture here. Bentonite absorbs moisture in the air and has the property of being recovered into crystal. Therefore, it is excellent in absorbing power to absorb moisture of 5 to 9 times its original volume, Lt; / RTI > Therefore, a substance such as bentonite whose volume increases upon absorption of water is applied to the first moisture absorption portion 404. In this case, it is possible to apply the bentonite to the first moisture absorption portion 404 as a single lump, but when applied in a form wrapped around the semi-permeable membrane, even when the volume is absorbed and the volume is increased in the future, So that it can be prevented from going out. It is also preferable that the second moisture absorption portion 405 is made of silica gel so as not to cause a change in volume but further comprises a stretchable film or the like which can spread widely corresponding to the volume change of the first moisture absorption portion 404 .

That is, when the first moisture absorption unit 404 expands due to the absorption of water, the color change pad 401 is gradually pushed outwardly of the through hole 403, thereby making it easier to confirm the color change through the naked eye have.

At this time, the hygroscopic moisture-absorbing structure 400 has the above-described configuration and can guide the life of the hygroscopic structure to the manager, etc. However, since it is usually used outdoors, (400) must be exchanged. If the number of the lighting apparatuses 100 is reduced to several tens, it is not a burden to replace the hygroscopic structure body 400 once every month. However, if the number of the hygienic structure bodies 400 is extremely increased, Can not be ignored. Therefore, the moisture absorption structure 400 is further provided with a structure capable of discharging the moisture again so that the moisture absorption structure 400 can be utilized for a longer time, so that the use time can be further increased.

To this end, the moisture absorbing structure 400 may further include a moisture absorbing packing 406, which is formed of a stretchable material and surrounds the moisture absorbing structure 400, and has a plurality of fine air holes. Although the moisture-absorbing packing 406 has been described in the above-mentioned configuration, the moisture-absorbing structure 400 can be maintained to have a constant shape, and an air flow hole is perforated to allow air to flow, (Ie, air or moisture particles can be distributed only to the extent that they can be flowed out). have.)

It is also possible to further include a dielectric material in the first moisture absorption portion 404 and the second moisture absorption portion 405 and to further apply a conductive adhesion material to the surface of the moisture absorption packing 406. [ Thus, in the periphery of the inner surface of the housing, preferably the inner surface of the cover 140, where the hygroscopic structure 400 is adhered, it is in contact with one surface of the hygroscopic packing 406, A voltage probe 411 and a shielding housing 412 surrounding the voltage head 411 may be further included. That is, if current is applied to the surface of the moisture absorption packing 406 without affecting the portion other than the surface of the moisture absorption packing 406 contacting with the voltage head 411 through the shielding housing 412, And ultimately may affect the first moisture absorption portion 404 and the second moisture absorption portion 405 including the dielectric material. These currents can interact with water molecules to force electrolysis of the water molecules, but more preferably the water molecules act on the sites associated with the silica gel or bentonite, thereby dropping water molecules from the silica gel or bentonite. That is, the absorbent absorbs the moisture, thereby allowing the absorbent to be used for a longer period of time. Of course, when the moisture absorption function is required, it is most preferable to continuously operate the voltage probe 410 in a period longer than one minute so that the structure for discharging the moisture does not affect the moisture absorption.

As described above, the construction and operation of a smart lighting system based on a power control communication lighting control according to the present invention are described in the above description and drawings. However, the present invention is not limited to the above description and drawings. And it is to be understood that various changes and modifications may be made without departing from the spirit of the invention.
