The mounting groove 110 is a portion into which the light emitting unit 200 is inserted, and may completely penetrate the center of the block body 100 vertically or be recessed only to a certain depth.

When the mounting groove 110 is recessed only to a certain depth, the drain hole 130 may be penetrated to the bottom surface.

Although not shown, a buffer ring may be interposed between the inner circumferential surface of the mounting groove 110 and the light emitting unit 200 as necessary. The buffer ring is a hollow ring made of an elastic material, and absorbs and disperses vertical pressure applied to the light emitting sidewalk block, thereby protecting the light emitting unit 200 from external shock.

The light emitting unit 200 is preferably installed detachably in the mounting groove 110 for maintenance. The light emitting unit 200 may accumulate sunlight and use it as an energy source for light emission, thereby omitting a wiring structure for receiving external power.

To this end, the light emitting unit 200 is built in the case 210, the case 210 is formed in the case 210, the solar cell 220, the case 210 is built in the case 210 as shown in Figure 3 It is defined as including a battery 230 charged with solar energy generated from the solar cell 220 and a light emitting module 240 embedded in the case 210 and powered by the battery 230 to emit light.

The upper surface of the case 210 may be placed on the same line as the upper surface of the block body 100 to minimize interference with pedestrians.

The solar cell 220 is disposed close to the upper surface of the case 210 and converts sunlight into electric power to produce electric power. The produced power is charged in the battery 230, and a circuit board for controlling charging and discharging of the battery 230 may be built in the case 210. A plurality of solar cell cells 220 may be disposed around the light emitting module 240.

Since the concept of the solar cell 220 and the battery 230 will be applied to a known solar charging system that generates and stores electricity using sunlight as an energy source, description of the internal circuit configuration and the like is omitted. I will do it.

The light emitting module 240 may be a known LED that is supplied with power from the battery 230 and emits light. A specific embodiment of the light emitting module 240 will be described later.

When the light emitting module 240 emits light, the emitted light may be transmitted to the outside through the upper surface of the case 210.

Although not shown, the light emitting unit 200 may further include an illuminance measurement sensor embedded in the case 210.

Can be controlled. To this end, the light emitting unit 200 may further include a control unit (not shown) that electrically connects the illuminance measurement sensor, the light emitting module 240, and controls the driving of the light emitting module 240 based on the illuminance value.

That is, the light emitting module 240 is driven to emit light based on the illuminance value measured by the illuminance measurement sensor, so that it does not emit light during daytime when there is no need for a light emission effect, and the surrounding area emits light only during dark nights to provide battery ( 230) can be used efficiently.

Hereinafter, a specific structure of the light emitting module 240 according to another embodiment of the light emitting unit 200 will be described with reference to the accompanying drawings. The same or similar parts to the above-described embodiment of the light emitting unit 200 will be omitted in detail to avoid overlapping.

The light emitting module 240, as shown in Figures 4 to 8, the shaft member 241 is installed across the inner space of the case 210, the rotating drum is axially coupled to the shaft member 241 is rotated 242, a plurality of light emitting diodes 243 that are mounted at equal intervals on the rotating drum 242 and emit light of different colors, and a plurality of first attached to each of the plurality of light emitting diodes 243 Conductive plate 244, the power supplied to the battery 230 in a state attached to the shaft member 241, according to the rotation of the rotating drum 242, the plurality of first conductive plate 244 It may be exemplified to include a second conductive plate 245 that is in contact with one and applies power to the first conductive plate 244 and a motor 246 that drives the rotating drum 242 to rotate.

The shaft member 241 is a fixed member fixed inside the casing, and the rotating drum 242 is rotated based on the shaft center of the shaft member 241.

The rotating drum 242 receives the rotational driving force of the motor 246 and rotates in one direction with the shaft member 241 as the rotation center. A first gear 242a may be formed in the rotating drum 242, and a second gear 246a may be formed at an output terminal of the motor 246, and the first gear 242a and the second gear 246a may be formed. The rotating drum 242 may be rotated by receiving the rotational driving force of the motor 246 by forming a meshing structure.

The driving of the motor 246 is not shown, but may be performed through an operation switch exposed to the outside of the case 210.

The rotating drum 242 may be manually rotated in addition to the rotational driving force of the motor 246. In this case, after opening the bottom surface of the case 210, the operator can directly rotate the rotating drum 242.

In the accompanying drawings, an example in which four light emitting diodes 243 are arranged on the rotating drum 242 with a phase difference of 90 degrees from each other is not particularly limited, but the number of light emitting diodes 243 is not particularly limited. Power is supplied to only one of the plurality of light emitting diodes 243 to emit light, and power is not supplied to the remaining light emitting diodes 243 except for the light emitting diodes 243. In addition, each of the plurality of light emitting diodes 243 may be attached with a color film of different colors to emit light of different colors, or a color lens may be additionally mounted.

The first conductive plate 244 is installed on each light emitting diode 243 and serves to supply power to the light emitting diode 243. The first conductive plate 244 forms a plate-like structure extending from the light emitting diode 243 toward the shaft member 241 passing through the center of the rotating drum 242.

When the rotating drum 242 is rotated, the light emitting diode 243 and the first conductive plate 244 may be rotated on the rotating drum 242 in conjunction with the rotating drum 242.

The second conductive plate 245 contacts one of the plurality of first conductive plates 244 to apply power supplied from the battery 230 to the first conductive plate 244.

The second conductive plate 245 is formed in a plate shape extending from the shaft member 241 toward the top, and is in contact with any one of the plurality of first conductive plates 244 extending toward the shaft member 241 to remove power. 1 Apply to the conductive plate 244.

Power can be applied only to the first conductive plate 244 contacting the second conductive plate 245, and only the light emitting diode 243 interlocked with the first conductive plate 244 to which the power is applied is operated to emit light. Can.

The first conductive plate 244 and the second conductive plate 245 are made of a metal plate. In particular, it is preferable that the first conductive plate 244 is formed in a thin thin plate shape so that a predetermined elastic deformation is possible.

The first conductive plate 244 is configured to be able to ride over the second conductive plate 245 while bending when the rotating drum 242 is rotated in contact with the second conductive plate 245.

Meanwhile, the light emitting unit 200 may further include a diffusion cover 250 mounted on the upper portion of the case 210 to transmit light emitted from the light emitting module 240.

In the above-described embodiment, the upper surface of the case 210 made of transparent or translucent may be made of the diffusion cover 250. The diffusion cover 250 may be detachably mounted on the upper part of the case 210.

When the rotating drum 242 is rotated and any one of the plurality of light emitting diodes 243 is located directly under the diffusion cover 250, the first conductive plate 244 and the second conductive plate 245 are in contact with each other. Power is supplied only to the light emitting diode 243 located directly under the diffusion cover 250.

That is, while only one light emitting diode 243 emits light, light emitted from the light emitting diode 243 passes through the diffusion cover 250 and shines outside.

On the other hand, around the top of the mounting groove 110 of the block body 100 is formed a recessed support groove 120 is recessed a certain depth, the upper end of the case 210, the flange of the elastic material inserted into the support groove 120 211 is formed, and the flange 211 may be formed with a mounting slit 212 penetrated in the transverse direction so that the diffusion cover 250 is inserted.

The flange 211 is a means for effectively distributing and supporting the vertical load acting on the light emitting unit 200, and is a part for inserting a particularly sharp tool to remove the light emitting unit 200 from the block body 100 Can be utilized.

For example, when the light emitting unit 200 is to be removed in the state where the light emitting unit 200 is mounted on the block body 100, the flange 211 is elastically deformed so that the flange 211 and the support groove 120 If a certain clearance is secured between the wall surfaces, and then the light emitting unit 200 is grasped and towed, the light emitting unit 200 can be easily removed from the block body 100.

The diffusion cover 250 can be mounted detachably on the upper portion of the case 210 by sliding on the mounting slit 212. Since the light emitting sidewalk blocks are installed on the ground, they are subjected to repeated loads by people passing by, and thus may be exposed to a fragile environment.

In particular, when damage to the diffusion cover 250 occurs, moisture penetrates into the case 210 and causes malfunctions of various electronic devices.

For this reason, it is preferable that the diffusion cover 250 is immediately replaced even if a minute breakage occurs. In order to replace the diffusion cover 250, first, the upper portion of the case 210 inserted into the mounting groove 110 is exposed, and then the handle 251 protruding outward from the mounting slit 212 in the mounted diffusion cover 250 By simply gripping and pulling, the diffusion cover 250 can be easily removed, and the replacement of the diffusion cover 250 can be completed simply by inserting the new diffusion cover 250 toward the mounting slit 212. .

That is, the self-illuminated sidewalk block according to the present invention greatly increases the convenience of maintenance by ensuring easy replacement of the diffusion cover 250.

Meanwhile, a diffuse reflection layer 252 may be formed at the center of the diffusion cover 250 to diffuse the transmitted light.

The diffuse reflection layer 252 is formed in a manner in which a certain range of the diffusion cover 250 is formed to be a rough surface, or irregularities are repeatedly formed so as to cause refraction of light transmitted through the diffusion cover 250 to provide a surface emission effect. Can be.

Meanwhile, a rotating cover 213 that opens and closes the lower portion of the case 210 may be mounted below the case 210. By opening the lower side of the case 210 with the pivoting cover 213, various components installed inside the case 210 can be replaced.

Hereinafter, the operation of the self-emitting sidewalk block according to the present invention will be described. In this operation, the process in which the light emitting module 240 is operated will be described as an example.

First, when the illuminance measurement sensor measures the illuminance to generate an illuminance value, the control unit determines whether to supply power to the second conductive plate 245 based on the illuminance value.

When the illuminance value measured by the illuminance measurement sensor is equal to or less than a preset reference illuminance value, power of the battery 230 is applied to the second conductive plate 245.

The power supplied to the second conductive plate 245 is supplied to the light emitting diode 243 through the first conductive plate 244 in contact with the second conductive plate 245 and directly under the diffusion cover 250. The positioned light emitting diode 243 is lit.

On the other hand, when the rotating drum 242 is rotated in one direction to change the color of light emitted from the self-luminous sidewalk block, the first conductive plate in contact with the second conductive plate 245 as shown in FIG. 9A ( 244) is elastically deformed, the first conductive plate 244 and the second conductive plate 245 are separated while riding on the second conductive plate 245.

Since the power supply to all the light emitting diodes 243 is stopped at the moment when the first conductive plate 244 is separated from the second conductive plate 245, all the light emitting diodes 243 are maintained in a turned off state, and then the rotating drum 242 As shown in Figure 9b according to the rotation of the first conductive plate 244 connected to the light emitting diode 243 that emits light of a different color is in contact with the second conductive plate 245, the light emitting diode 243 The power is supplied to the light emitting diode 243 is driven to emit light.

In other words, since the plurality of light emitting diodes 243 that emit light of different colors are arranged on the rotating drum 242 with a phase difference of 90 degrees, each time the rotating drum 242 is rotated at 90 degree intervals, they are different. It is possible to emit light of color.

When a plurality of self-emitting sidewalk blocks configured as described above are constructed one after another as shown in FIG. 10, changing the color of light emitted from each light emitting unit 200 enables a variety of atmospheres, as well as light emission. It is possible to form one overall picture or figure through a combination of colors of light, and visualize a plurality of light-emitting units 200 in an arrow pattern pointing in a specific direction and emphasize it in color, thereby enhancing pedestrian safety. It can also be used as a sign for pedestrian guidance.

The embodiments of the present invention described above are merely exemplary, and those skilled in the art to which the present invention pertains will appreciate that various modifications and other equivalent embodiments are possible. Therefore, it will be understood that the present invention is not limited to the forms mentioned in the above detailed description. Therefore, the true technical protection scope of the present invention should be determined by the technical spirit of the appended claims. In addition, it should be understood that the present invention includes all modifications, equivalents, and substitutes within the spirit and scope of the invention as defined by the appended claims.
