In this sense, the background and prerequisite situations are different from those of the fixed road signs shown in Patent Document 1. On the other hand, in construction indicator lights as well, a flowing flashing operation with a high line-of-sight guiding effect for passers-by is required.

[0005] An object of the present technology is to provide a flashing construction indicator light that is easy to use at a construction site and can achieve a flowing flashing with a high line-of-sight guiding effect.

Embodiments for Carrying Out the Invention

[0013] Embodiments of the present technology will be described below. In cases where the same or corresponding parts are given the same reference numerals, the description may not be repeated.

[0014] In the embodiments described below, when referring to the number, quantity, etc., unless otherwise specified, the scope of the present technology is not necessarily limited to such number, quantity, etc. Also, in the following embodiments, each component is not necessarily essential for the present technology, unless otherwise specified. Further, the present technology is not limited to necessarily achieving all the operational effects mentioned in the present embodiment.

[0015] In this specification, the descriptions of "comprise", "include", and "have" are in an open - ended form. That is, when a certain configuration is included, other configurations outside the said configuration may or may not be included.

[0016] In addition, in this specification, when geometric terms and terms representing positional and directional relationships, such as "parallel", "orthogonal", "45° oblique", "coaxial", "along", etc., are used, these terms allow for manufacturing errors or slight variations. In this specification, when terms representing relative positional relationships, such as "upper side", "lower side", etc., are used, these terms are used to indicate the relative positional relationship in one state, and depending on the installation direction of each mechanism (for example, turning the entire mechanism upside down, etc.), the relative positional relationship can be reversed or rotated at an arbitrary angle.

[0017] FIG. 1 and FIG. 2 are diagrams showing the flashing construction indicating lamp according to the present embodiment, FIG. 1 is a perspective view, and FIG. 2 is a side sectional view.

[0018] As shown in FIGS. 1 and 2, the construction indicating lamp 100 includes a main body 1, a light emitting portion 2, a battery storage portion 3, an upper unit 4, a solar panel 5, and a substrate 6.

[0019] The main body 1 includes a pedestal 101 and cover members 102A and 102B. The cover members 102A and 102B are fixed to the pedestal 101 and constitute the first surface 1A and the second surface 1B of the main body 1, respectively. The cover members 102A and 102B are made of a transparent material and transmit the light from the light emitting portion 2.

[0020] The light emitting portion 2 includes LED elements 2A and 2A1 (first light emitting portion) provided on the first surface 1A (front surface) side of the main body 1 and LED elements 2B and 2B1 (second light emitting portion) provided on the second surface 1B (rear surface) side of the main body 1.

[0021] The LED elements 2A and 2A1 are composed of green LEDs, and the LED elements 2B and 2B1 are composed of red LEDs. That is, in the present embodiment, the LED elements 2A and 2A1 (first light emitting portion) and the LED elements 2B and 2B1 (second light emitting portion) emit light of different colors. However, the LED elements 2A and 2A1 and the LED elements 2B and 2B1 may be composed of LEDs of the same color.

[0022] The LED elements 2A and 2A1 emit light along the direction of arrow A (the first direction), and the LED elements 2B and 2B1 emit light along the direction of arrow B (the second direction). That is, in the present embodiment, the LED elements 2A and 2A1 (the first light emitting part) and the LED elements 2B and 2B1 (the second light emitting part) emit light along directions that are approximately 180° opposite to each other.

[0023] The LED elements 2A and 2B are provided at a plurality of locations (for example, five locations) at equal intervals in the circumferential direction on the outer peripheral portion (the first region) of the substantially circular substrate 6. The LED elements 2A1 and 2B1 are provided at one location in the central portion (the second region) of the substrate 6.

[0024] In the construction indicator lamp 100, an indicator (not shown) is provided separately from the LED elements 2A, 2A1, 2B, and 2B1 that constitute the light emitting part 2. The indicator can be constituted by an LED element smaller than the LED elements 2A, 2A1, 2B, and 2B1 that constitute the light emitting part 2.

[0025] The upper unit 4 is provided on the side of the main body 1 opposite to the battery storage part 3, that is, on the upper side of the main body 1. A solar panel 5 is stored in the upper unit 4.

[0026] The substrate 6 includes two substrates 6A and 6B facing each other. The LED elements 2A and 2A1 are mounted on the substrate 6A, and the LED elements 2B and 2B1 are mounted on the substrate 6B. The substrates 6A and 6B are stored in the main body 1.

[0027] FIG. 3 is a view showing a state in which the construction indicator lamp 100 is attached to the upper part of the load cone 1000. As shown in FIG. 3, the construction indicator lamp 100 is attached to the load cone 1000 by inserting the battery storage part 3 into an opening provided at the upper end of the load cone 1000. At the construction site, the load cones 1000 to which the construction indicator lamps 100 are attached are arranged at substantially equal intervals. Thereby, pedestrians can be visually guided. In FIG. 3, the upper unit 4 and the solar panel 5 stored therein are not shown.

[0028] The construction indicator lamp 100 shown in FIGS. 1 to 3 is an example, and the scope of the present technology is not limited thereto. For example, instead of the construction indicator lamp 100 attached to the road cone 1000, a construction indicator lamp directly placed on the road surface may be used. Further, the shape or the light emission direction of the main body 1 and the light emitting unit 2 is not limited to the examples in FIGS. 1 to 3. For example, the main body 1 may be rectangular, or the light emitting unit 2 that emits arrow-shaped light may be used. The light emission directions of the light emitting unit 2 on the first surface 1A side and the second surface 1B side of the main body 1 may intersect obliquely at an angle other than 180°. Furthermore, the shape or arrangement of the battery storage unit 3 and the upper unit 4 is not limited to the examples in FIGS. 1 to 3.

[0029] FIG. 4 is a block diagram showing a system in the construction indicator lamp 100, and FIG. 5 is a simplified block diagram shown in FIG. 4.

[0030] As shown in FIGS. 4 and 5, the construction indicator lamp 100 further includes a button 7 (switch), a voltage detection circuit 8 (sensor), a battery 9, a booster 10, and a control unit 11.

[0031] The button 7 is for operating the control unit 11 that controls the light emission pattern of the light emitting unit 2. However, the form of the switch in the present technology is not limited to the button 7, and any form that can switch the ON / OFF of the construction indicator lamp 100 may be used.

[0032] The voltage detection circuit 8 is connected to the solar panel 5 and discriminates between day and night by detecting the output voltage thereof. As a result of the day / night discrimination, if it is determined to be daytime, the operation of the light emitting unit 2 is stopped, and the battery 9 is charged by the solar panel 5.

[0033] The battery 9 can be stored in the battery storage unit 3. The battery 9 is connected to the light emitting unit 2 via the booster 10. The battery 9 is also connected to the control unit 11.

[0034] The control unit 11 includes a transceiver 11A (communication unit) and an MCU 11B. The MCU 11B is connected to each LED element constituting the light emitting unit 2 and can control the light emission timing and light emission pattern of each of them. The light emitting unit 2 (LED), the voltage detection circuit 8, and the control unit 11 (transceiver 11A and MCU 11B) constitute a module 12, and the module 12 is housed in the main body 1.

[0035] Since the control unit 11 includes the transceiver 11A, the construction indicator light 100 can perform wireless communication (2.4 GHz) with other construction indicator lights. When a plurality (hereinafter, an example of a set of four will be exemplarily described, but the scope of the present technology is not limited thereto) of construction indicator lights 100 are used in combination, ranks (first, second, third, fourth) are assigned to each construction indicator light 100 according to the order in which the power of the construction indicator light 100 is turned on. According to this rank (product number), the light emission order of each construction indicator light 100 in the flowing blinking described later is set.

[0036] Further, the wireless communication includes information (first information) regarding the light emission timing of the light emitting unit 2 and information (second information) regarding the light emission pattern of the light emitting unit 2. The first information and the second information can be shared among a plurality of construction indicator lights 100. Thereby, it becomes possible to match or correspond (that is, synchronously blink) the light emission timing and light emission pattern of the light emitting unit 2 among a plurality of construction indicator lights 100.

[0037] FIG. 6 is a diagram for explaining the transition of the operation mode of the construction indicator light 100. FIGS. 7 to 11 are diagrams (timing charts) showing the blinking modes in each of "Power ON" (FIG. 7), "Pairing Mode" (FIG. 8), before reaching "Power OFF" (FIG. 9), "Synchronization NG Mode" (FIG. 10), and "Operation Mode 1" to "Operation Mode 3" (FIG. 11) shown in FIG. 6, respectively.

[0038] In the "Power OFF" state, all LEDs including the indicator are turned off. By performing a "long press" operation of continuously pressing button 7 for a predetermined time (for example, about 2 to 3 seconds) or more from the "Power OFF" state, the construction indicator light 100 shifts to the "Power ON" state, and each LED element blinks in the manner shown in FIG. 7. FIG. 7(A) shows the blinking mode of the LED element 2A or LED element 2A1 provided on the first surface 1A side of the main body 1, and FIG. 7(B) shows the blinking mode of the LED element 2B or LED element 2B1 provided on the second surface 1B side of the main body 1.

[0039] When it is determined that the residual voltage is sufficient when shifting to the "Power ON" state, the LED elements 2A and 2B provided on the outer peripheral portions of the substrates 6A and 6B blink in the manners shown in FIGS. 7(A) and 7(B), respectively. On the other hand, when it is determined that the residual voltage is not sufficient, the LED elements 2A1 and 2B1 provided in the central portions of the substrates 6A and 6B blink in the manners shown in FIGS. 7(A) and 7(B), respectively.

[0040] After each LED element blinks a predetermined number of times in the manner shown in FIG. 7, the construction indicator light 100 transitions to the "Pairing Mode" shown in FIG. 8. FIGS. 8(A) and 8(B) show the blinking modes of the LED elements 2A and 2A1 provided on the substrate 6A, respectively, and FIGS. 8(C) and 8(D) show the blinking modes of the LED elements 2B and 2B1 provided on the substrate 6B, respectively. FIG. 8(E) shows the blinking mode of the indicator.

[0041] When synchronously blinking a plurality of construction indicator lights 100, first turn on the power of the first construction indicator light 100, and after confirming that the display mode of its light emitting part 2 has transitioned to the "Pairing Mode" (FIG. 8), turn on the power of the second construction indicator light 100. When the pairing between the first and the second is successful, the two construction indicator lights 100 shift to the "Operation Mode 1" (flowing blink).

[0042] After confirming the transition of the two construction indicator lights 100 to "Operation Mode 1" to "Operation Mode 3", turn on the power of the third construction indicator light 100. When the third construction indicator light 100 transitions to the "Pairing Mode" (Figure 8) and successfully pairs with other construction indicator lights 100, the third construction indicator light 100 also transitions to "Operation Mode 1" to "Operation Mode 3" (flowing flashing).

[0043] After confirming the transition of the three construction indicator lights 100 to "Operation Mode 1" to "Operation Mode 3", turn on the power of the fourth construction indicator light 100. When the fourth construction indicator light 100 transitions to the "Pairing Mode" (Figure 8) and successfully pairs with other construction indicator lights 100, the fourth construction indicator light 100 also transitions to "Operation Mode 1" to "Operation Mode 3" (flowing flashing).

[0044] In addition, in the pairing mode, if synchronization with other construction indicator lights 100 is not successful within a predetermined time, the construction indicator light 100 transitions to the "Synchronization NG Mode" (Figure 10). Figure 10(A) shows the flashing pattern of the LED elements 2A, 2A1 provided on the substrate 6A, and Figure 10(B) shows the flashing pattern of the LED elements 2B, 2B1 provided on the substrate 6B. Figure 10(C) shows the flashing pattern of the indicator.

[0045] When the construction indicator light 100 transitions to the "Synchronization NG Mode", if the button 7 is "long pressed", it transitions to "Power OFF". At this time, only the indicator flashes in the pattern shown in Figure 9 for a predetermined time and then transitions to "Power OFF".

[0046] When the button 7 is "short pressed" (a pressing operation less than the predetermined time) in the "Synchronization NG Mode", the construction indicator light 100 returns to the "Pairing Mode".

[0047] The four construction indication lights 100 that have shifted to "Operation Mode 1" (flashing flow) flash in the manner shown in Fig. 11. Figs. 11(A) to 11(D) respectively show the flashing modes of the light-emitting parts 2 of the first to fourth construction indication lights 100. Fig. 11(E) shows the flashing mode of the indicators of the four construction indication lights 100 (the same for all four).

[0048] As shown in Fig. 11, in the four construction indication lights 100, the flashing flow of the LED elements 2A, 2A1 (first light-emitting part) on the first surface 1A side and the flashing flow of the LED elements 2B, 2B1 (second light-emitting part) on the second surface 1B side proceed in opposite directions to each other.

[0049] That is, the flashing flow of the LED elements 2A, 2A1 (first light-emitting part) on the front side proceeds from the first construction indication light 100 towards the fourth construction indication light 100, while the flashing flow of the LED elements 2B, 2B1 (second light-emitting part) on the back side proceeds from the fourth construction indication light 100 towards the first construction indication light 100. Therefore, from the front side and the back side, the same visual guidance can be provided to pedestrians.

[0050] By performing a "short press" operation on button 7 in "Operation Mode 1" to "Operation Mode 3", the "operation mode" is switched. Specifically, the switching from "Operation Mode 1" to "Operation Mode 2", from "Operation Mode 2" to "Operation Mode 3", and from "Operation Mode 3" to "Operation Mode 1" is performed. Note that the "operation mode" may be one or two, or four or more. When button 7 is "long pressed" in "Operation Mode 1" to "Operation Mode 3", the state becomes "power off".

[0051] In "operation mode 1" to "operation mode 3" according to this embodiment, the light emitting unit 2 blinks in the manner shown in FIG. 11, but the blinking periods are different from each other. For example, in "operation mode 1", T1 = 2.16 s and T2 = 720 ms, while in "operation mode 2", T1 = 1.08 s and T2 = 360 ms, and in "operation mode 3", T1 = 0.72 s and T2 = 240 ms. That is, the flowing blinking in "operation mode 2" and "operation mode 3" proceeds at 2 times and 3 times the speed of the flowing blinking in "operation mode 1", respectively.

[0052] FIG. 12 and FIG. 13 are diagrams showing examples of the flowing patterns of the flowing blinking in the construction indicator lamp 100. In the example of FIG. 12, the state ((A) to (D)) in which four (one set) of the construction indicator lamps 100 are arranged is shown, and in the example of FIG. 13, the state ((A) to (H)) in which eight (two sets) of the construction indicator lamps 100 are arranged is shown.

[0053] FIG. 13 shows an example in which two sets of the four (one set) of the construction indicator lamps 100 shown in FIG. 12 are arranged and used. Note that the number of units in one set is not limited to four. Also, three or more sets of the construction indicator lamps 100 may be arranged and used.

[0054] The flowcharts of FIGS. 14 and 15 specifically explain the operation of the construction indicator lamp 100. Note that the flows shown in FIGS. 14 and 15 are merely examples, and the scope of the present technology is not limited thereto.

[0055] As shown in FIG. 14, from the "Power OFF" state, at S10, by performing a "long press" operation on the button 7 (SW), the "Power ON" state is entered. At S20, it is determined whether to shift to the "Test Mode". When the test pin on the substrate 6 is shorted and the button 7 is "long pressed" for 3 seconds or more, the "Test Mode" is entered. In the "Test Mode", it is possible to individually perform lighting or extinguishing tests of each LED element, voltage display tests of the battery 9, day / night discrimination tests, communication tests, etc. Note that the "Test Mode" is not necessarily essential for the construction indicator light 100, and a construction indicator light 100 without the "Test Mode" may also be used.

[0056] At S31 to S33, the remaining voltage of the battery is checked. At S31, when the voltage is less than a predetermined value (1.9V), all LED elements (all LEDs) including the indicator are turned off. At S32, when the voltage recovers (2.3V or more), it returns to the "Power ON" state. At S33, when the voltage of the battery 9 satisfies a predetermined condition (2.1V or more), it shifts to the "Pairing Mode" after 3 seconds.

[0057] As shown in FIG. 15, at S40, when synchronization with another construction indicator light 100 is successful, it shifts to the "Operation Mode 1" (flowing blinking 1). When synchronization is not successful within 90 seconds, it shifts to the "Synchronization NG Mode". At S50 (S51 to S53), by performing a "short press" operation on the button 7 (SW), the "Operation Mode 1" (flowing blinking 1), "Operation Mode 2" (flowing blinking 2), and "Operation Mode 3" (flowing blinking 3) are switched. When in the "Operation Mode" state of S50, day / night discrimination (S60) and voltage monitoring (S70) are continuously performed. Also, at S80, by performing a "long press" operation on the button 7 (SW), only the indicator blinks for 15 seconds and then all LED elements are turned off, entering the "Power OFF" state.

[0058] As described above, the construction indication lamp 100 according to the present embodiment includes a main body 1 including a first surface 1A and a second surface 1B facing each other, LED elements 2A, 2A1 (first light emitting part) provided on the first surface 1A side, LED elements 2B, 2B1 (second light emitting part) provided on the second surface 1B side, a button 7 (switch) operable from the outside of the construction indication lamp 100, a transceiver 11A for transmitting and receiving information regarding the light emission of the light emitting part 2, and an MCU 11B (control part) for controlling at least the timing of the light emission of the light emitting part 2.

[0059] The transceiver 11A can communicate with other construction indication lamps 100 by wireless communication. The information transmitted and received by the transceiver 11A includes information regarding the timing of the light emission of the light emitting part 2 (first information) and information regarding the light emission pattern of the light emitting part 2 (second information).

[0060] Based on the information of other construction indication lamps 100 received from the receiving part of the transceiver 11A, the MCU 11B synchronizes its own light emission with the light emission of other construction indication lamps 100 (more specifically, makes the timing and light emission pattern of the light emission coincide or correspond), and can cause the light emitting parts 2 of a plurality of construction indication lamps 100 to flash in a flowing manner.

[0061] More specifically, by pressing the button 7, it is possible to switch the ON / OFF of the power supply of the construction indication lamp 100. Also, the order of light emission in the flowing flashing of the light emitting part 2 is set in the order in which the power supply of the construction indication lamp 100 is changed from the OFF state to the ON state. Further, by operating the button 7, it is also possible to switch the light emission pattern (operation mode) of the construction indication lamp 100.

[0062] In the set of the construction indicator lamp 100 according to the present embodiment, the flowing flashing of the LED elements 2A and 2A1 (the first light emitting part) and the flowing flashing of the LED elements 2B and 2B1 (the second light emitting part) proceed in opposite directions to each other. By doing so, it becomes possible to realize the flowing flashing that proceeds in the traveling direction of the passerby (driver, rider, pedestrian, etc.) when viewed from both sides of the construction indicator lamp 100. As a result, it is possible to realize a flowing flashing operation with a high line-of-sight guiding effect on the passerby.

[0063] Also, it is possible to synchronously flash a plurality of construction indicator lamps 100 by wireless communication. Further, since the order of the flowing flashing is set according to the order in which the power is turned on without distinguishing between the master unit and the slave unit, it is possible to provide a set of construction indicator lamps 100 that are easy to use at the construction site. By combining and using a plurality of sets, it is possible to cope with the length of the installation section.

[0064] In the present embodiment, an example in which the flowing flashing of the first light emitting part on the front side and the flowing flashing of the second light emitting part on the back side proceed at the same speed (same cycle) has been described. However, the flowing speed of the first light emitting part on the front side and the flowing speed of the second light emitting part on the back side may be made different from each other.

[0065] As described above, the embodiments of the present technology have been described. However, it should be considered that the embodiments disclosed this time are illustrative in all respects and not restrictive. The scope of the present technology is indicated by the claims, and it is intended that all modifications within the meaning and scope equivalent to the claims are included.
