Description

An embodiment of the present invention relates to a lighting device.

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

As information distribution of services, 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, and by mounting this beacon on a lighting device installed on the ceiling, service information can be transmitted to the terminals of users who use the facility. ..

By attaching this beacon to an emergency light or guide light equipped with a storage battery, there is a method of driving the beacon by supplying electric power from the storage battery even in the event of a disaster (see Patent Document 1).

However, emergency lighting devices such as emergency lights and guide lights are required by law to be inspected regularly, and the power supply from commercial power sources is temporarily cut off during inspections. It is necessary to switch to a storage battery. When the inspection is carried out, the power supplied to the beacon is momentarily interrupted due to the switching of the power supply source from the external power source to the storage battery. Therefore, if the inspection work is performed while the information is being transmitted from the beacon, there is a problem that the information transmission is interrupted due to the influence of the momentary interruption of the electric power, causing a sense of discomfort.

On the other hand, the communication unit 14 is driven by the electric power supplied from the external power source 18, and transmits the service information stored in the storage unit to the outside.
[At the time of inspection]

The operation of the lighting device 10 at the time of 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 electric power of the lighting device 10 is supplied, a shaded region shows an region where the electric power is supplied from the external power source 18 and is driven, and a dotted region is an region where the electric power is supplied and driven from the storage battery 12.

On the other hand, since the first switching unit 21 is in a separated state, the power of the external power supply 18 is not supplied to the control unit 13, but the communication unit 14 is connected to the external power supply 18 via the control circuit, so that it is external. The electric 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 supply 18 can be continuously supplied to the communication unit 14, so that the service information can be stably provided from the communication unit 14. can.

Therefore, even if the inspection operation is performed while the service information is being transmitted from the communication unit 14, the electric 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 the electric power of the lighting device 10 is supplied, and the dotted line region is an region where the electric power is supplied from the storage battery 12 and is driven. Further, FIG. 8 shows the operation of the first switching unit 21 and the second switching unit 22 in an emergency. Here, the emergency is a case where the power supply from the external power source 18 is cut off due to, for example, a disaster. When the power supply from the external power supply 18 is cut off 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 received the signal turns off the first switching unit 21 to separate the control circuit from the charging circuit / discharging circuit, and turns on the second switching unit 22 to form the charging circuit / discharging circuit. The light source 11 is connected to the light source 11. As a result, 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 a separated state, the power of the storage battery 12 is not supplied to the communication unit 14. Therefore, in an emergency, the communication unit 14 stops operating. When the power supply 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 source 18 is supplied to the storage battery 12, and the storage battery 12 charges the electric power (FIG. 3). In this way, in an emergency, the electric power of the storage battery 12 can be used to light the light source 11 by turning off the first switching unit 21.

Next, the lighting device 10 of the second embodiment will be described.

The basic configuration of the lighting 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 lighting device 10 are different.

In the control circuit of the lighting device 10 of the second embodiment, when the power supply from the external power source 18 is cut off and the power failure detection signal is received from the power failure detection unit 16, the first switching unit 21 and the second switching unit 21 Is controlled, 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 the first information in the storage unit, and emergency information such as evacuation route information as the second information. That is, the types of the first information and the second information are different. The communication unit 14 transmits the first information to the outside during normal use and inspection. On the other hand, when the switching notification signal is received from the control circuit in an emergency, the second information is transmitted to the outside.

At the time of inspection, the inspection unit 15 estimates the power consumption when the communication unit 14 is driven by the power of the storage battery 12 in an emergency, and inspects the storage battery 12.

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

The operation of the lighting device 10 in an emergency will be described with reference to FIGS. 9, 10 and 11. FIG. 10 shows a region where the electric power of the lighting device 10 is supplied, and the dotted line region is an region where the electric power is supplied from the storage battery 12 and is driven. FIG. 9 shows a configuration example of the lighting device 10 of the second embodiment. Further, FIG. 11 shows the operation of the first switching unit 21 and the second switching unit 22 in an emergency. Here, the emergency is a case where the power supply from the external power source 18 is cut off due to, for example, a disaster. When the power supply from the external power supply 18 is cut off 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 receives this signal transmits a power supply switching notification signal to the communication unit 14, and turns on the first switching unit 21 to connect the control circuit and the charging circuit / discharging circuit to the second switching state. The unit 22 is turned on to connect the charging circuit / discharging circuit and the light source 11. As a result, the electric power of the storage battery 12 is supplied to the light source 11 via the charging circuit / discharging circuit of the control unit 13 and is supplied to the communication unit 14 via the control circuit. Here, the communication unit 14 is driven by the electric power of the storage battery 12, and receives the switching notification signal transmitted from the control circuit to call the second information from the storage unit and transmit it to the outside. That is, in the event of a disaster, the lighting device 10 can transmit information from the communication unit 14 while turning on the light source 11 by the electric power of the storage battery 12.

Further, when the control unit circuit determines that the power for lighting the light source 11 for a predetermined time is insufficient for the storage battery 12, the first switching unit 21 is turned off to cut off the power supplied to the communication unit 14, and the storage battery 12 is connected. The electric power may be supplied preferentially to the light source 11. As a result, it is possible to transmit emergency information while turning on the light source in the event of a disaster, and it is possible to give priority to the light source 11 and turn it on for a predetermined time.

When the power supply from the external power 18 is restored after recovery from the emergency, the control circuit turns off the second switching unit 22 and supplies the power of the external power supply 18 to the storage battery 12 as in the case of normal use. 12 charges the electric power and transmits a switching notification signal to the communication unit 14. The communication unit 14 that has received the switching notification signal is supplied from the external power supply 18 and is driven by electric power to call the first information from the storage unit and transmit it to the outside.
[At the time of inspection]

The operation at the time of inspection of the second embodiment is the same operation as at the time of inspection of 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 electric power of the storage battery 12 is supplied to the light source 11 and the communication unit 14, if the communication unit 14 consumes 10% of the storage battery 12, the inspection unit 15 estimates that 10% is consumed at the time of inspection, and the storage battery 12 is consumed. Inspect.

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 inspects the storage battery 12, so that the storage battery 12 can be inspected in the event of a disaster. An inspection result equivalent to that when power is supplied to the light source 11 and the communication unit 14 can be obtained. As a result, since the inspection can be performed under the same conditions as in the event of a disaster, information can be provided from the communication unit 14 while the light source 11 is turned on for a predetermined time even in the event of a disaster.

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

The lighting device 10 of the first embodiment and the second embodiment has described the case of an emergency light, but 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 supply 18 or the storage battery 12 is supplied to the light source 11 by connecting the control unit 13 and the light source 11 even during normal use, inspection, and emergency, the light source 11 is always lit. Can be kept.

Although embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other embodiments, and various omissions, replacements, and changes can be made without departing from the gist of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are also included in the scope of the invention described in the claims and the equivalent scope thereof.
