Description

  Embodiments described herein relate generally to a lighting device.

  In recent years, with the spread of portable terminal devices such as mobile terminals and smartphones, systems that perform service information distribution using a network such as advertisement distribution via the network are increasing. Service information distribution using the network includes various forms such as distribution of information such as evacuation sites and event information in an emergency such as a disaster in addition to advertisement distribution.

As service information distribution, for example, a system using a beacon is considered. A beacon is a wireless communication device that transmits data by wireless communication such as infrared communication. By mounting this beacon on a lighting device installed on the ceiling, service information can be transmitted to a terminal of a user who uses the facility. .

  There is a system in which a beacon is driven by supplying power from a storage battery even when a disaster occurs by attaching this beacon to an emergency light or a guide light equipped with a storage battery (see Patent Document 1).

However, emergency lighting devices such as emergency lights and guide lights require that the emergency lighting devices be inspected regularly by law, and the power supply from the commercial power supply is temporarily cut off during the inspection. It is necessary to switch to a storage battery. When the inspection is performed, the power supplied to the beacon is momentarily interrupted as the power supply source is switched from the external power source to the storage battery. Therefore, when inspection work is performed while information is being transmitted from the beacon, there is a problem in that information transmission is interrupted due to the effect that power is interrupted for a moment.

FIG. 8 shows operations of the first switching unit 21 and the second switching unit 22 during normal use. In normal use, the control circuit of the control unit 13 turns on the first switching unit 21 to put it in the connected state, and turns off the second switching unit 22 to put the control unit 13 and the light source 11 in the separated state. Thereby, the control part 13 charges the storage battery 12 by supplying the electric power of the external power supply 18 to the storage battery 12 via a charging circuit / discharge circuit. Further, since no power is supplied to the light source 11, the light source 11 is turned off. On the other hand, the communication unit 14 is driven by the power supplied from the external power source 18 and transmits the service information stored in the storage unit to the outside.
[When checking]

The operation of the illumination device 10 during inspection will be described with reference to FIGS. 5, 6, and 8. FIG. 5 shows a configuration example of the lighting device 10. FIG. 6 shows a region where the power of the lighting device 10 is supplied. A hatched region indicates a region driven by power supplied from the external power source 18, and a dotted line region indicates a region driven by power supplied from the storage battery 12. It is. FIG. 8 shows operations of the first switching unit 21 and the second switching unit 22 during inspection. When the inspection operator enters the inspection mode by operating the inspection switch, the control unit of the control unit 13 turns off the first switching unit 21 and separates the control circuit of the control unit 13 from the charging circuit / discharge circuit. At the same time, the second switching unit 22 is turned on and the control unit 13 and the light source 11 are connected. As a result, the charging circuit / discharging circuit supplies the power stored in the storage battery 12 to the light source 11 to turn on the light source 11. At this time, the inspection unit 15 checks whether the storage battery 12 operates normally by detecting the voltage, current, temperature, discharge time, and number of discharges of the storage battery 12, and stores the inspection information in the storage unit. Output. On the other hand, since the first switching unit 21 is in the separated state, the power of the external power source 18 is not supplied to the control unit 13, but the communication unit 14 is connected to the external power source 18 via the control circuit and thus externally. The power of the power source 18 is supplied to the communication unit 14. That is, even if the first switching unit 21 is separated for inspection, the power of the external power source 18 can be continuously supplied to the communication unit 14, so that service information can be stably provided from the communication unit 14. it can.

Therefore, even if an inspection operation is performed during transmission of service information from the communication unit 14, power can be supplied to the communication unit 14 without interruption.
[Emergency]

The operation of the lighting device 10 in an emergency will be described with reference to FIGS. 5, 7, and 8. FIG. 5 shows a configuration example of the lighting device 10. FIG. 7 shows a region where power of the lighting device 10 is supplied, and a dotted line region is a region where power is supplied from the storage battery 12 and driven. FIG. 8 shows the operations of the first switching unit 21 and the second switching unit 22 in an emergency. Here, an emergency is a case where the supply of power from the external power source 18 is interrupted due to, for example, a disaster. When the supply of power from the external power supply 18 is interrupted in an emergency, the power failure detection unit 16 determines that it is an emergency and transmits a power failure detection signal to the control circuit of the control unit 13. The control circuit that has received the signal turns off the first switching unit 21 to separate the control circuit and the charging circuit / discharging circuit, and turns on the second switching unit 22 to turn on the charging circuit / discharging circuit. The light source 11 is connected. Thereby, the electric power of the storage battery 12 is supplied to the light source 11, and the light source 11 is turned on. Here, since the first switching unit 21 is in the separated state, the power of the storage battery 12 is not supplied to the communication unit 14. Therefore, the communication unit 14 stops operating in an emergency. When the supply of power from the external power 18 is restored after recovery from the emergency, the control circuit turns on the first switching unit 21 and turns off the second switching unit 22 in the same manner as in normal use. The electric power of the external power supply 18 is supplied to the storage battery 12, and the storage battery 12 charges electric power (FIG. 3). Thus, in an emergency, the power of the storage battery 12 can be used for lighting the light source 11 by turning off the first switching unit 21.

Next, the illuminating device 10 of 2nd Embodiment is demonstrated.

The basic configuration of the illumination device of the second embodiment is the same as that of the first embodiment, but some of the functions of the power failure detection unit 16, the communication unit 14, and the inspection unit 15 of the illumination device 10 are different.

When the power supply from the external power supply 18 is cut off and the power failure detection signal is received from the power failure detection unit 16, the control circuit of the lighting device 10 of the second embodiment has the first switching unit 21 and the second switching unit. And a switching notification signal indicating that the power supply source has been switched from the external power supply 18 to the storage battery 12 is transmitted to the communication unit 14.

The communication unit 14 stores service information such as products and events recommended by the store as first information and emergency information such as evacuation route information as second information in the storage unit. That is, the first information and the second information are different in type. The communication unit 14 transmits the first information to the outside during normal use and inspection. On the other hand, when a switching notification signal is received from the control circuit in an emergency, the second information is transmitted to the outside.

The inspection unit 15 inspects the storage battery 12 by estimating the power consumption when the communication unit 14 is driven by the power of the storage battery 12 in an emergency at the time of inspection.

Next, the operation of the second embodiment will be described.
[Emergency]

The operation of the illumination device 10 in an emergency will be described with reference to FIGS. FIG. 10 shows a region where the power of the lighting device 10 is supplied. A dotted line region is a region where power is supplied from the storage battery 12 and driven. FIG. 9 shows a configuration example of the illumination device 10 of the second embodiment. FIG. 11 shows operations of the first switching unit 21 and the second switching unit 22 in an emergency. Here, an emergency is a case where the supply of power from the external power source 18 is interrupted due to, for example, a disaster. When the supply of power from the external power supply 18 is interrupted in an emergency, the power failure detection unit 16 determines that it is an emergency and transmits a power failure detection signal to the control circuit of the control unit 13. The control circuit that has received this signal transmits a power switch notification signal to the communication unit 14, turns on the first switch unit 21, connects the control circuit and the charging circuit / discharge circuit, and performs the second switching. The unit 22 is turned on and the charging circuit / discharging circuit and the light source 11 are connected. Thereby, the electric power of the storage battery 12 is supplied to the light source 11 through the charging circuit / discharge circuit of the control unit 13 and to the communication unit 14 through the control circuit. Here, the communication unit 14 is driven by the power of the storage battery 12 and receives the switching notification signal transmitted from the control circuit, thereby calling the second information from the storage unit and transmitting it to the outside. That is, the lighting device 10 can transmit information from the communication unit 14 while turning on the light source 11 with the power of the storage battery 12 at the time of a disaster.

In addition, when the storage unit 12 determines that the power for turning on the light source 11 for a predetermined time is insufficient, the control unit circuit turns off the first switching unit 21 and cuts off the power supplied to the communication unit 14. Electric power may be supplied to the light source 11 with priority. As a result, emergency information can be transmitted while turning on the light source during a disaster, and the light source 11 can be turned on for a predetermined time with priority.

When the supply of power from the external power 18 returns after recovery from an emergency, the control circuit turns off the second switching unit 22 and supplies the power of the external power source 18 to the storage battery 12 in the same way as in normal use. 12 charges power and transmits a switching notification signal to the communication unit 14. The communication unit 14 that has received the switching notification signal is driven by power supplied from the external power supply 18 and calls the first information from the storage unit and transmits it to the outside.
[When checking]

The operation at the time of inspection in the second embodiment is the same as that at the time of inspection in the first embodiment. The difference is that the inspection unit 15 inspects the storage battery 12 by estimating the power consumption when the communication unit 14 is driven by the power of the storage battery 12 in an emergency. For example, when the power of the storage battery 12 is supplied to the light source 11 and the communication unit 14, when the communication unit 14 consumes 10% of the storage battery 12, it is estimated that the inspection unit 15 is consumed 10% at the time of inspection. Conduct inspections.

That is, the communication unit 14 is driven by the power of the external power 18 at the time of inspection, but the inspection unit 15 estimates the power consumed by the communication unit 14 and performs the inspection of the storage battery 12, thereby An inspection result equivalent to the case where power is supplied to the light source 11 and the communication unit 14 is obtained. Thereby, since it can check on the conditions equivalent to the time of a disaster, information can be provided from the communication unit 14 while turning on the light source 11 for a predetermined time even at the time of a disaster.

As described above, the lighting device 10 can supply power to the communication unit 14 without interruption even if an inspection operation is performed during transmission of service information from the communication unit 14, and in addition, the power of the storage battery 12 can be supplied in an emergency. Can provide emergency information.

The lighting device 10 of the first and second embodiments has been described for the case of an emergency light. However, when the lighting device 10 is a guide light, the second switching unit 22 is always turned on. That is, since the power of the external power source 18 or the storage battery 12 is supplied to the light source 11 by connecting the control unit 13 and the light source 11 to the light source 11 even during normal use, inspection, and emergency, the light source 11 is always in a lighting state. Can keep.

Although the embodiment of the present invention has been described, this embodiment is presented as an example and is not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
