<Embodiment 1>
<Summary of Embodiment 1>

  A perspective conceptual view of the construction lamp of this embodiment is shown in FIG. 1A is an external view, and FIG. 1B is an internal perspective view. FIG. 2 is a functional block diagram of the construction lamp shown in FIG. The construction lamp according to the present embodiment is arranged in a solar panel portion (0102, 0201) arranged on the top surface (0101) of the main body, an LED lamp portion (0103, 0202) arranged toward the side surface of the main body, and a lower portion of the main body. A storage battery unit (0104, 0203) for storing electric power from the solar cell, and a radio clock unit (0106, 0204) having a solenoid coil-shaped radio clock antenna (0105, 0204) disposed on the upper body along the solar cell panel 0205) and a control unit (0107, 0206) that controls each unit and can control blinking of the LED lamp unit at a timing determined according to time.

  The “solar cell panel unit” is disposed on the top surface of the main body, and generates electric power for the LED lamp of the LED lamp unit, which will be described later, to emit light using light such as sunlight during the daytime. The solar cell panel portion is arranged on the top surface to which light such as sunlight hits most efficiently in the construction lamp of this embodiment. The size of the solar cell panel is a size that can sufficiently generate electric power necessary for the construction light to light up and blink at night. The electric power generated by the solar cell panel is stored by charging a storage battery unit described later. Since the solar cell panel is composed of silicon as a main raw material, it does not have an electromagnetic shielding effect, and even if a solenoid coil is disposed immediately below, it does not interfere with reception of the solenoid coil.

  The “LED lamp part” is arranged toward the side surface of the main body, and is lit or blinks by the electric power stored in the storage battery part. The LED lamp unit has an LED as a light emitter, and the light emitted from the LED lamp is configured to be emitted toward the side surface of the construction lamp main body. Moreover, the LED lamp part arrange | positioned at the construction light of this embodiment may be one as shown in FIG. 3, and may be arrange | positioned plurally in the vertical direction as shown in FIG. In the case of a construction lamp having a plurality of LED lamp units, the LED lamp units may be arranged in the vertical direction, or two in the horizontal direction and two in the vertical and horizontal directions.

  Furthermore, the LED lamp part may have a plurality of LED lamps or a single LED lamp. Further, the emission color of the LED lamp may be blue, green, white, etc., in addition to a warning color such as red or orange. A plurality of types of colors may be combined. Further, in the case of a construction lamp having a plurality of LED lamp portions, the color may be changed by the individual LED lamp portions.

  The “storage battery unit” stores electric power generated from the solar battery panel. The storage battery unit is a secondary battery such as a nickel metal hydride battery or a lithium ion battery. The storage battery unit needs to have a capacity capable of sufficiently storing the amount of power required for the LED lamp of the LED lamp unit to emit light for a predetermined time. Moreover, the storage battery part is arranged in a cylindrical part for installation at the lower part of the construction light and at the upper part of the single tube or the cone. By disposing the battery part, which is heavier than other members, at the lower part of the construction light, the center of gravity of the construction light is lowered and the stability when installed is increased. Further, if the storage battery unit is installed so as to fit into the cylindrical part at the top of the single tube or the cone, it is possible to prevent the machine from coming into contact with the storage battery and reduce problems such as liquid leakage. Furthermore, even when the diameter of the cylindrical part is relatively large and there is room between it and the storage battery part, the storage battery part becomes a weight and the whole is relatively easy to stand upright. There is no need to adjust the direction.

  The “radio clock part” has a solenoid coil-shaped antenna for receiving standard time radio waves along the solar cell panel at a position that does not hinder the power generation of the solar cell panel.

  The radio clock unit starts receiving standard time radio waves (JJY) when the main power switch provided at the lower part of the construction lamp body is turned on. When the standard time signal is received, the construction lamp adjusts its own internal timer. Based on this timer, the LED lamp blinks. The reception of the standard time radio wave is always performed regularly with the main power turned on and the LED lamp not blinking. As a specific adjustment method of the internal timer, for example, adjustment is performed by resetting the timer by receiving a position marker and a marker included in the standard time radio wave. By resetting, the timer values (counts, etc.) of the individual construction lights are set to 0, so that the timer values of all the construction lights can be made uniform.

FIG. 4 shows an example of standard time radio waves. Standard time radio waves are transmitted in the order of minute, hour, day, year, day of the week, and leap second in one minute (other data may be included). Markers (M) (0401) and position markers (P0 to P5) (0402, 0403, 0404, 0405, 0406, 0407) for identifying information are transmitted during this time or hour. This marker and position marker are received and the internal timer is reset. The internal timer is reset when the three signals M and P1 are received starting from the rising edge of the signal P0 in the figure. That is, the timer is reset 11 seconds after receiving P0. As a result, all the internal timers of the individual construction lights are reset at the same time, and all have the same count.

  The construction lamp according to the present embodiment is characterized in that the time when the radio clock unit receives the standard time radio wave is not the timing when the LED lamp starts to blink, but when the main power is turned on. The construction lights and road fences having the radio timepiece shown in the conventional example are fixed and are assumed to be installed in a specific place. For this reason, the standard time radio wave can always be received. However, it is assumed that the construction lamp of this embodiment is not fixed at a specific location, but is periodically removed and turned off. For this reason, when not in use, the main power supply is in an OFF state, and the standard time radio wave cannot be received. Also, if the standard time radio wave is received only at the timing when the LED lamp starts blinking and the timer is adjusted, it takes about 11 seconds to receive the standard time radio wave as described above. There is a time lag before the lamp lights up. Furthermore, when the standard time radio wave cannot be received at the timing of starting blinking, there is a possibility that the blinking timing of each construction light is shifted. For this reason, the radio clock unit starts receiving the standard time radio wave when the main power of the construction lamp is turned on regardless of the blinking timing of the LED lamp. In addition, if standard time radio waves are received while the LED lamp is flashing, there will be a problem that the standard time radio waves cannot be received correctly due to noise generated by the flashing of the LED lamp. May shift. Therefore, in the construction lamp of this embodiment, the standard time radio wave is received in a state where the LED lamp is not blinking, and the internal timer is adjusted.

  Here, an example of the processing flow of the radio clock part of the construction lamp of this embodiment will be described. First, when the main power is turned on, the internal timer starts counting. Next, it is determined whether or not the current construction LED lamp should be blinked. This determination will be described later. When it is not necessary to blink the LED, the standard time radio wave is received. When the LED is normally received, the internal timer is reset. The solenoid coil may have a core or may not have a core, but the one having the core improves the receiving sensitivity. And the core is weak against heat, and when the temperature rises, the reception sensitivity is lowered, but the solar cell panel arranged directly above serves as a heat shielding plate, so it is more than arranging the solenoid coil in other parts It is possible to receive radio waves with good sensitivity.

  The “control unit” controls each unit and controls blinking of the LED lamp unit at a timing determined according to time. The control unit starts energization of the LED lamp unit when the LED lamp unit starts blinking such as at night or falls below a predetermined brightness. For example, when an illuminance sensor is provided on a construction light and the brightness falls below a predetermined brightness, the LED lamp is energized, or the LED lamp is energized based on the standard time signal received by the radio clock. May be. At this time, in order to avoid troubles such as the blinking of the LED lamp part not being started due to the influence of automobile headlights or road construction lighting, two methods of control by brightness and control by time are used in combination. It is desirable to do.

  Further, the control unit controls the blinking pattern of the LED lamp. For example, as shown in FIG. 5, the flashing of all construction lights is repeated at the same timing, or the upper and lower flashes are swapped as shown in FIG. 6, or as shown in FIG. The LED lamps may be blinked one by one, and the LED lamps may be blinked so as to flow.

  FIG. 8 shows a schematic diagram illustrating an example of a configuration when the respective components of the construction lamp according to the present embodiment are realized as hardware. As shown in this figure, the guide light of this embodiment includes a CPU (0801) and a main memory (0802) for performing various arithmetic processes, and a flash memory and a hard disk for holding a blinking pattern of the LED lamp. And an interface (0804) to which a storage device (0803) such as a ROM, an antenna for receiving standard time radio waves, an LED lamp, a timer for synchronizing the blinking of the LED lamp, and the like are connected. These are connected to each other by a data communication path (0805) such as a system bus, and perform transmission / reception and processing of information. The main memory provides a work area that is a work area for the program as well as a program for performing various types of processing. In addition, each main memory and storage device is assigned multiple memory addresses, and programs executed by the CPU perform processing by exchanging data with each other by specifying and accessing the memory addresses. Is possible.

Here, the hardware movement of the construction lamp of this embodiment will be described. First, when the main power is turned on, a program for operating the timer is read from the storage device and developed on the main memory. The CPU operates a timer according to a program developed on the main memory. Next, the CPU determines the environment where the construction light is currently placed, and determines whether or not to blink the LED. If it is necessary to blink the LED lamp, the CPU lamp blinks the LED lamp in a predetermined blinking pattern. When it is not necessary to blink the LED lamp, the CPU receives the standard time radio wave via the antenna, and resets the timer based on the reception result. The CPU sequentially determines whether it is necessary to blink the LED lamp, receives standard time radio waves, and resets the timer.
<Embodiment 1 effect>

By having the radio clock part as in the construction light of the present embodiment, it is possible to align the blinking patterns of the LED lamps of the construction light even with a plurality of construction lights.

The present embodiment is a construction characterized in that the LED lamps of the LED lamp portion of the construction lamp shown in the first embodiment are arranged in a plurality of petals, and the LED lamp further has a bowl-shaped reflecting mirror. It is a light.
<Embodiment 2 configuration>

  The construction lamp according to the present embodiment includes an LED lamp in which the LED lamp portion is arranged in a petal shape and a bowl-shaped reflecting mirror having an opening in the lower area of the LED lamp. Further, the LED lamps arranged in the petal shape of the construction lamp of the present embodiment are arranged so as to be inclined so as to have an angle of 45 degrees with respect to the background surface on which the LED lamps are installed.

FIG. 9 shows a conceptual diagram of the LED lamp portion of the present embodiment. (A) is a conceptual perspective view, (b) is a conceptual plan view when the LED lamp is viewed from the direction of light irradiation, and (c) is a cross-sectional view taken along the line AA shown in (b). . In FIG. 9, the number of LED lamps (0901, 0902, 0903, 0904, 0905) is five, and LED lamps (0902, 0903, 0904, 0905) other than the LED lamp (0901) arranged at the center are the substrates. The pedestal (0906, 0907, 0908, 0909) installed on the top is inclined at an angle of 45 degrees. Since the LED lamp generally has a narrow light irradiation angle, the surrounding LED lamps are inclined at an angle of 45 degrees in order to irradiate light over a wider range. Further, by disposing a bowl-shaped reflecting mirror (0910) so as to surround the periphery of the LED lamp, it becomes possible to irradiate light emitted from the LED lamp more efficiently. Moreover, the light irradiated from the LED lamp is irradiated only to the surface where the LED lamp of the construction lamp main body is arranged. As shown in FIG. 10A, in a construction lamp that does not have a reflecting mirror, when the construction lamp is made of a material that easily transmits light such as resin, LED lamps (1001, 1002) are arranged in the direction of the side of the construction lamp. ) Light leaks. This leakage of light may be mistaken for pedestrians, bicycles, and automobiles that are guidance targets. However, as shown in FIG. 10 (b), in the construction lamp of this embodiment, the light emitted from the LED lamps (1005, 1006) leaks in the lateral direction by having the reflecting mirrors (1003, 1004). There is no such thing, and there is no risk of pedestrians, bicycles, and cars misidentifying. Since the lower area of the LED lamp is a portion where the main functional parts such as the wiring of the LED element are concentrated, the deterioration of the element may be stopped when receiving heat of sunlight through the reflecting mirror. Therefore, in order to protect the portion directly underneath, that is, the weak portion of the LED lamp from heat, no reflecting mirror is arranged in that portion.
<Embodiment 2 effect>

Like the construction lamp of the present embodiment, the LED lamps are arranged in a petal shape, and further provided with a bowl-shaped reflecting mirror, it becomes possible to make the light emitted from the LED lamps appear larger and the visibility is improved.
<Embodiment 3>
<Overview of Embodiment 3>

The present embodiment is a construction lamp having an LED lamp arranged in a petal shape and having a bowl-shaped reflector, wherein the LED lamp is arranged with an inclination of 45 degrees with respect to the vertical direction of the construction lamp. It is a construction light. Furthermore, the LED lamp cover on the light trace emitted from the LED lamp is provided with one corresponding lens for each LED lamp, and is configured to diffuse light.
<Embodiment 3 configuration>

  In the construction lamp of this embodiment, the LED lamp portion is arranged with an LED lamp corresponding to a petal with an inclination of 45 degrees with respect to the vertical direction when the lamp is installed, and each LED lamp is a bullet-type LED lamp. An LED lamp cover having an independent lens for each LED lamp is provided at a position on the light trace in the bullet direction of the LED lamp.

  FIG. 11 shows a conceptual diagram of the construction lamp of this embodiment. The construction lamp shown in FIG. 11 is a construction lamp in which two LED lamp sections (1101, 1102, 1103, and 1104) are arranged on the upper and lower sides. In the construction lamp according to the present embodiment, the LED lamps arranged in the petal shape of the LED lamp section are arranged with an inclination of about 45 degrees with respect to the vertical direction of the construction lamp. (A) of FIG. 11 is a case where there is no inclination with respect to the vertical direction of the construction lamp, and (b) is the construction lamp of this embodiment, and the LED lamp is approximately 45 degrees in the vertical direction. This is an example in which they are arranged with an inclination (1105, 1106).

  Here, the LED lamp of this embodiment of this embodiment is a bullet-type LED lamp section lamp. The bullet type LED lamp emits the strongest light from the tip of the bullet shape. Therefore, “on the bullet direction light trail” is a light trail of light emitted from the bullet-shaped tip, where the light emitted from the bullet-type LED lamp is the strongest. In the construction lamp of the present embodiment, the bullet-shaped direction light trace of the light emitted from the LED lamp is as shown in FIG. FIG. 12 is a conceptual cross-sectional view when the LED lamp portion of the construction lamp is viewed from the side. Of the LED lamps arranged in a petal shape, light emitted from the central LED lamp (1201) is directly irradiated toward the LED lamp cover (1202). On the other hand, the bullet-shaped direction light traces of the light emitted from the other LED lamps (1203, 1204) are reflected by the bowl-shaped reflecting mirror (1205) and irradiated toward the LED lamp cover. At this time, in the LED lamp of the embodiment, the lens (1206, 1207, 1208) is provided at a location on the LED lamp cover where the bullet-shaped light traces irradiated from the individual LED lamps pass. The lens provided on the LED lamp cover is a lens for diffusing light emitted from the LED lamp.

  FIG. 13 is a view of a construction lamp in which two LED lamp portions are arranged vertically, as viewed from the front, and is a conceptual diagram for explaining the spread of light emitted from the LED lamp. (A) is a case where the LED lamp does not have an inclination with respect to the vertical direction of the construction lamp, and (b) is the construction lamp of this embodiment, and the LED lamp is approximately 45 degrees in the vertical direction. It is an example arranged with an inclination. In the construction lamp of (a), the lower LED lamp (1302) arranged in the upper LED lamp part (1301) and the upper LED lamp (1304) arranged in the lower LED lamp lamp part (1303). The distance (1305) becomes closer. For this reason, the intensity of light emitted from this vicinity is increased. On the other hand, the LED lamps on the left and right of the LED lamps that are close to each other have a long distance (1306, 1307), and thus the light intensity is weak. For this reason, when the LED lamp does not have an inclination with respect to the vertical direction of the construction lamp, the light emitted from the construction lamp becomes non-uniform. On the other hand, in the construction lamp of (b), the intervals between the LED lamps of the upper and lower LED lamp sections (1308, 1309) are equal (1310, 1311), so that the light emitted from the construction lamp becomes uniform.

Further, the visibility when the construction lamp is viewed from the side surface differs depending on whether or not the LED lamp is disposed with an inclination of approximately 45 degrees with respect to the top of the construction lamp. FIG. 14 shows a conceptual diagram when the construction light is viewed from the side. (A) is a case where the LED lamp does not have an inclination with respect to the vertical direction of the construction lamp, and (b) is the construction lamp of this embodiment, and the LED lamp is approximately 45 degrees in the vertical direction. It is an example arranged with an inclination. In the case of (a), there are only two LED lamp cover lenses (1401 and 1402) in total, one on the top and one on the side, whereas the LED lamp is approximately 45 degrees in the vertical direction as shown in (b). When the lens is disposed with an inclination of (2), it is possible to visually recognize a total of four lenses (1403, 1404, 1405, 1406), two at the top and bottom. That is, it is possible to improve the visibility from the side surface direction by tilting the LED lamp approximately 45 degrees with respect to the vertical direction of the construction lamp.
<Embodiment 3 effects>

Like the construction lamp in this embodiment, the LED lamp is arranged with an inclination of 45 degrees with respect to the top / bottom direction of the construction lamp, so that the visibility of the construction lamp from the side direction is improved and the entire construction lamp is irradiated. It is possible to make the emitted light uniform. Furthermore, it is possible to diffuse light over a wider range by providing a lens on the LED lamp cover from which light emitted from the LED lamp is emitted. In addition, by installing a lens for each LED lamp, it is possible to reduce the production cost and to easily observe the LED lamp from outside the construction lamp as compared to the case where the lens is installed on the entire LED lamp cover. Improves.

  In the LED lamp portion shown in FIG. 15, the light emitted from the LED lamp arranged at the center is directly irradiated to the outside of the construction lamp through the LED lamp cover. At this time, a lens as shown in Embodiment 3 may be used. The light emitted from the LED lamps arranged so that the bullet-shaped direction light traces are directed in the vertical direction or the horizontal direction of the construction light is reflected by the bowl-shaped reflector (1506) and passes through the LED lamp cover (1507). Is irradiated outside the construction lamp. At this time, like the LED lamp arranged at the center, the lens (1508, 1509, 1510) of the LED lamp cover may be used. As shown in FIG. 15C, the light emitted from the LED lamps arranged so that the bullet-shaped direction light traces are directed in the vertical direction or the horizontal direction of the construction light is 90 degrees with respect to the bullet-shaped direction. The angle may be irradiated from the construction light, or the angle of the bowl-shaped reflector may be adjusted so that the construction light is emitted in a wider range.

In the example shown in FIG. 15, the example in which the number of LED lamps is five is shown, but the number of LED lamps may be changed according to the purpose of use or the like. For example, a construction light in which the central LED lamp is omitted and the number of LED lamps is four may be used.
<Embodiment 4 Effect>

<Overview of Embodiment 5>

In the present embodiment, the construction lamp control unit according to the first embodiment, the second embodiment, the third embodiment, and the fourth embodiment turns on the LED lamp of the LED lamp unit according to the amount of power generated by the solar cell panel.

  The control unit of the present embodiment has a measurement circuit that measures the electromotive force in the solar cell panel. In the measurement circuit, the electromotive force of the solar cell panel is measured, and when the electromotive force is equal to or greater than a predetermined value, the control unit stores the electric power generated by the solar cell panel in the storage battery unit. Conversely, when the electromotive force measured by the measurement circuit falls below a predetermined value, the control unit needs less light for the solar panel to generate power, that is, there is an environment where a construction light is installed. Judged to be dark. Based on this, the control unit controls the energization switch so that the electric power stored in the storage battery unit is energized to the LED lamp, the energization to the LED lamp is started, and the LED lamp is turned on or blinks.
