(Embodiment)
Hereinafter, an embodiment which is a specific example of the present invention will be described with reference to the drawings. In addition, the concrete secondary product 1 concerning this embodiment applies this invention to a walkway boundary block.

  FIG. 1 is an external view of a concrete secondary product 1.

  The concrete secondary product 1 includes a concrete 11 and an LED unit 12 embedded in the concrete 11.

  The concrete 11 is, for example, a sidewalk boundary block as shown in FIG. The bottom surface of the concrete 11 has, for example, a rectangular shape whose length in the longitudinal direction is 60 centimeters and whose length in the lateral direction is 25 centimeters.

  Further, the concrete 11 has a cross section cut by a plane perpendicular to the above-described longitudinal direction. For example, the length of the upper base is 18 centimeters, the length of the lower base is 25 centimeters, and the height is 25. It has a substantially trapezoidal shape of centimeter. Curvatures are provided at both ends of the upper base so that pedestrians or the like collide with each other to avoid injury.

  As will be described later, the LED unit 12 includes an LED 121 that is appropriately lit, a solar cell 122 that generates power using sunlight, a power storage unit 123 that stores electrical energy generated by the solar cell 122, and a control described later. It has the part 124 and the case 125 which accommodates them.

  In addition, in this embodiment, LED121 comprises a light emission part, and the solar cell 122 comprises a power generation part. As described above, the LED 121 is a light emitting diode.

  The case 125 has, for example, a dodecahedron shape as shown in FIG. When viewed from above, the LED unit 12 is embedded in the concrete 11 and has, for example, a square shape with a vertical and horizontal length of 6 centimeters and a height of 9 centimeters. Among the 9 centimeters, for example, 4 centimeters protrude upward from the top surface of the concrete 11.

  For example, the case 125 is made of a synthetic resin whose upper five surfaces are transparent, and can transmit sunlight and light generated by the LEDs 121.

  The case 125 houses the LED 121, the solar battery 122, the power storage unit 123, the control unit 124, and the like in a watertight manner with respect to the outside, and is buried in the concrete 11 at least partially solidified.

  More specifically, the case 125 is sealed with, for example, a silicon-based sealing agent having strong adhesiveness so as to fit together in a state where the elements such as the LEDs 121 are accommodated. Further, the contact portion between the case 125 and the concrete 11 is also bonded with the same silicon-based sealing agent. Since the upper and lower fitting portions of the case 125 are buried in the concrete 11, the case 125 cannot be opened and closed in the concrete secondary product 1.

  For example, four LEDs 121 are provided for one LED unit 12. Further, the LED 121 is turned off when it is bright such as daytime, and is turned on or blinking when it is dark such as nighttime, according to control of the control unit 124 described later.

  The solar cell 122 generates light by converting light energy of sunlight into electric energy.

  The solar cell 122 is disposed inside the case 125, for example, at a central portion, and is easy to receive sunlight irradiated from above.

  The power storage unit 123 is, for example, an electric double layer capacitor that stores electrical energy generated by the solar battery 122.

  As will be described later, the control unit 124 determines whether the electrical energy generated by the solar battery 122 is generally stored in the power storage unit 123 or whether the electrical energy stored in the power storage unit 123 is used for the light emission of the LED 121. However, when the electrical energy generated by the solar battery 122 is used for the light emission of the LED 121 while being stored in the power storage unit 123, the electrical energy generated by the solar battery 122 and the electrical energy charged by the power storage unit 123 are simultaneously emitted by the LED 121. It may be used for.

  Specifically, the control unit 124 determines whether to perform the above-described power storage or light emission based on the brightness of light transmitted through the transparent portion on the upper surface of the LED unit 12. That is, the control unit 124 determines the external brightness by the sensor included in the control unit 124, and controls the amount of electricity supplied from the power storage unit 123 to the LED 121 based on the determination result. This will be described later.

  For example, the concrete secondary product 1 can store power in the power storage unit 123 during the daytime and can emit light by the LED 121 at night.

  Since the concrete secondary product 1 has the above-described configuration, the one-package LED unit 12 can be embedded in the concrete 11, the cost is low, maintenance is unnecessary, theft damage can be avoided, and the design landscape. The above is also preferable.

  FIG. 4 is a diagram illustrating the control flow of the LED unit 12. As described above, the LED unit 12 stores the electrical energy generated by the solar cell 122 in the power storage unit 123 or emits the LED 121 by the electrical energy stored in the power storage unit 123 according to the determination performed by the control unit 124. Let

  The control unit 124 emits light from the LED 121 and the electricity generated by the solar cell 122 in accordance with the magnitude relationship between external brightness measured by a sensor included in the control unit 124 and a plurality of predetermined threshold values. The power storage by the energy storage unit 123 is controlled.

(1) When the external brightness measured by the sensor is less than the first threshold, that is, very dark, the control unit 124 causes the LED 121 to emit light only by the electrical energy stored in the power storage unit 123. At that time, power storage by the power storage unit 123 is not performed.

(2) When the external brightness measured by the sensor is greater than or equal to the first threshold value and less than the second threshold value (where the first threshold value is less than the second threshold value), that is, when it is dim, the control unit 124 The LED 121 is caused to emit light by the electric energy stored in 123 and the electric energy generated by the solar cell 122. At that time, power storage by the power storage unit 123 is not performed.

(3) When the external brightness measured by the sensor is greater than or equal to the second threshold value and less than the third threshold value (where the second threshold value is less than the third threshold value), that is, when the brightness is faint, the control unit 124 The LED 121 is caused to emit light by the electric energy generated by the battery 122, and surplus electric energy is stored in the power storage unit 123.

(4) When the external brightness measured by the sensor is equal to or greater than the third threshold value, that is, sufficiently bright, the control unit 124 does not cause the LED 121 to emit light, and the electrical energy generated by the solar cell 122 is stored in the power storage unit 123. To store electricity.

  Under the control of the control unit 124 described above, appropriate light emission of the LED 121 according to the external brightness and power storage by the power storage unit 123 are performed. In addition, the control rule of (1)-(4) mentioned above is an example, Comprising: For example, according to the luminous efficiency of the solar cell 122, (3) is not provided and can be variously changed.

  FIG. 5 is an external view of the concrete secondary product 1 according to this modification.

  When the concrete 11 is viewed from above in a state of being disposed on the road surface, the concrete 11 has a substantially flat plate shape having a vertical and horizontal length of 30 cm and a height of 6 cm, for example.

  The LED unit 12 has a substantially flat plate shape with a vertical and horizontal length of 8 centimeters and a height of 4 centimeters, for example, when viewed from above in a state of being disposed on the road surface.

  By embedding the LED portion 12 in the concrete 11, the concrete secondary product 1 is used as shown in FIG. 6, for example. By using the concrete secondary product 1 in this way, for example, it is convenient when a pedestrian or the like walks a sidewalk at night.

  Moreover, the shape, length, distance, and the like of each element of the concrete secondary product 1 described above are merely examples, and other elements may be used.

  Therefore, although the LED part 12 has the shape of a icosahedron and a part protrudes above the concrete 11, the LED part 12 may have another shape, and the LED part 12 is the concrete 11. The upper surface may be flat as a whole without protruding upward.

  Further, for example, a concrete secondary product 1 for a land boundary block or a pedestrian boundary block as shown in FIG. 7 may be employed.

  The LED 121 may be any other light emission mechanism that constitutes the above-described light emitting unit. Therefore, the LED 121 may be replaced with, for example, an incandescent bulb or a fluorescent lamp.

  Moreover, the solar cell 122 may be any other power generation mechanism that constitutes the above-described power generation unit. Therefore, the solar cell 122 may be replaced by, for example, a button battery.

  In addition, the energy generated by the vibration of the vehicle may be stored in the power storage unit 123 as electrical energy, and the LED 121 may be lit, and the traveling direction may be indicated by the light or used as a monument. For this purpose, the above-described power generation unit needs to include a vibration power generation mechanism.

  Further, the power storage unit 123 is, for example, an electric double layer capacitor, but may be any other mechanism that can store power.

  The control unit 124 may not be provided if there is no particular problem.

  In general, since the electrical system is susceptible to alkali corrosion, the electrical system of the LED unit 12 may be coated to prevent alkali permeation. For example, it is conceivable to wrap the electrical system with a polycarbonate sheet or the like. However, the present invention is not limited to this.

  Further, although the silicon-based sealing agent is used as the adhesive, any other adhesive sealing agent may be used to fill the gap between the LED portion 12 and the concrete 11. Moreover, if there is no particular problem, such an adhesive or substance may not be used.

  In addition, as described above, the concrete secondary product 1 is preferably any one of the ground boundary block, the pedestrian boundary block, the road plate, the sidewalk plate, and the car stop, but the present invention is limited to this. is not. Therefore, the concrete secondary product 1 may be used, for example, for a pedestal of an illuminated signboard as shown in FIG.

  The concrete secondary product according to the present invention is very convenient if it is placed at various traffic sites used by pedestrians and vehicles, and is expected to contribute to the so-called production industry by being produced and sold in large numbers. .
