The lighting device 1 will be described as an emergency lighting fixture that is turned on in an emergency, such as a power outage or disconnection, when power is not supplied to the lighting device 1 from a commercial power source provided outside the lighting device 1.

The main body 2 has a cylindrical shape with an opening formed on one side. The main body 2 has a ceiling mounting spring 21. The main body 2 houses a light source unit 4, a storage battery unit 5, and a control unit 6.

The ceiling mounting spring 21 is a spring formed of a sheet metal with a curved surface. The ceiling attachment spring 21 is a mounting member for attaching the lighting device 1 to a portion to which the lighting device 1 is attached, such as a ceiling or a wall, which is a structure to which the lighting device 1 is attached.

The frame 3 is disk-shaped and is attached to the main body 2 so as to close an opening formed in the main body 2. The frame 3 is formed with a hole through which a part of the light source unit 4 and a part of the control device 5 housed in the main body 2 are exposed.

FIG. 3 is a diagram showing the configuration of a light source unit 4, which will be described later, of the lighting device 1 of the first embodiment. As shown in FIGS. 2 and 3, the light source unit 4 includes a mounting board 41, a light source section 42, a lens 43, a pseudo load 44, and a heat dissipation section 45, and is housed in the main body 2 and connected to the control unit 6. It is removable.

The mounting board 41 has a light source section 42 and a pseudo load 44 mounted on one side.

The light source section 42 is an LED (Light Emitting Diode) that is supplied with power and emits light. Further, the light source section 42 will be described as being an LED, but is not limited to this, and may be any light emitting element that emits light when supplied with power, such as an organic EL or a laser diode.

The lens 43 is attached to the mounting board 41 so as to cover the light source section 42, and is exposed to the outside of the main body 2 through a hole formed in the frame 3. The lens 43 condenses or diffuses the light emitted by the light source section 42.

The pseudo load 44 is composed of an electric resistance element or the like, and converts the supplied electric power into heat. The pseudo load 44 is mounted on the mounting board 41. The pseudo load 44 generates heat when power is supplied, thereby increasing the temperature of peripheral components of the pseudo load. The amount of heat generated by the pseudo load 44 is limited by the supplied power, the number of installed pseudo loads 44, and the layout. The pseudo load 44 can prevent the light source unit 42 from turning on when an automatic inspection of the lighting device 1, which will be described later, is performed and the user feels a sense of discomfort or is able to prevent the user from misperceiving that there is an emergency. . Note that the pseudo load 44 may be mounted not only on the mounting board 41 but also on the control unit 6.

The heat dissipation section 45 is a heat sink that is attached so as to be in contact with the surface of the mounting board 41 opposite to the surface on which the light source section 42 is mounted, and dissipates heat generated when the light source section 42 emits light. Alternatively, the heat radiating section 45 is a heat sink that radiates heat generated when power is supplied to the pseudo load 44. The heat dissipation section 45 has a heat dissipation capacity that corresponds to the amount of heat generated by the light source section 42 or the amount of heat generated by the pseudo load 44 .

FIG. 4 is a block diagram schematically showing the configuration of the lighting device 1 according to the first embodiment. As shown in FIGS. 2 and 4, the storage battery unit 5 includes a storage battery 51 and a storage section 52. The storage battery unit 5 is housed in the main body 2 and is detachable from the control unit 6.

The storage battery 51 is a nickel-hydrogen storage battery (hereinafter referred to as a Ni-MH storage battery). The storage battery 51 is charged with power supplied from a commercial power source. The storage battery 51 is charged by rapid charging when the remaining battery power is low, and trickle charging is performed in which a small amount of electric power is supplied to charge the storage battery 51 when the remaining battery power is large. Further, the storage battery 51 supplies power to the light source section 42 when the supply of power from the commercial power supply is stopped. Here, the storage battery 51 has been described as a Ni-MH storage battery, but is not limited to this, and may be a nickel cadmium storage battery (also referred to as a Ni-Cd storage battery) or a lithium ion battery (also referred to as a Li-Ion battery). ) may be used as a secondary battery.

The storage unit 52 stores storage battery information indicating the state of the storage battery 51. The storage unit 52 is a storage medium such as an IC (Integrated Circuit) chip or an RFID (Radio Frequency Indentifier) tag, and stores battery information from the control unit 5 or an external terminal using either a contact or non-contact method. This is what is written to and read from. The storage battery unit 5 is provided with a socket, a connector, or a housing that is connected to the storage section when the storage section 52 and a control device 63 to be described later are electrically connected by a contact method.

The storage battery information is information for determining whether or not the storage battery 51 can be used continuously. The storage battery information is, for example, a lighting continuation time that is the time from when the light source 42 starts lighting with the power supplied from the storage battery 51 until it ends lighting.

As shown in FIGS. 2 and 4, the control unit 6 includes a lighting circuit 61, a charging circuit 62, a control device 63, a notification section 64, an inspection switch 65, and a light receiving section 66. The control unit 6 is housed in the main body 2.

The lighting circuit 61 performs lighting control regarding turning on or off the light source section 42, and supplies power from the storage battery 51 to the light source section 42 to cause the light source section 42 to emit light when the power supply from the commercial power source is stopped. It is something.

The charging circuit 62 receives power supplied from a commercial power source and charges the storage battery 51.

The control device 63 is a device that controls operations of the lighting device 1 such as lighting and inspection in the lighting device 1. The control device 61 includes, as hardware, a processing device such as a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), a flash memory, and an EPROM (Erasable Programmer). ble Read Only Memory), EEPROM The microcomputer or microcontroller includes a storage section consisting of a nonvolatile or volatile semiconductor memory such as an electrically erasable programmable read only memory (Electrically Erasable Programmable Read Only Memory). The control device 63 includes an inspection processing section 63A, a clock section 63B, a determination section 63C, a writing section 63D, an acquisition section 63E, and a status confirmation section 63F.

The inspection processing unit 63A causes the charging circuit 62 to stop supplying power from the commercial power supply to the storage battery 51, causes the lighting circuit 61 to supply power from the storage battery 51 to the light source unit 42, lights up the light source unit 42, and causes the light source unit 42 to turn on. This is an inspection function that obtains the possible lighting continuation time, which is the time from when the lighting starts using the electric power supplied from the storage battery 51 until the lighting ends. Note that the inspection processing unit 63A is not limited to the possible lighting continuation time, and may have any inspection function that obtains storage battery information.

The timing unit 63B has a timer function that measures the elapsed time when power is supplied from the commercial power source and the time that the light source 42 can continue lighting after it starts lighting with the power supplied from the storage battery 51 until it ends lighting. be.

The determination unit 63C has a function of determining whether or not the storage battery 51 can be used. The determination unit 63C stores a threshold value for determining whether or not the storage battery 51 can be used. The determining unit 63C compares the storage battery information stored in the storage unit 52 with a threshold value to determine whether the storage battery 51 is usable. Here, the threshold value is a specified value for determining whether the storage battery 51 can be used in the item of storage battery information.

A case where the storage battery information is the possible lighting continuation time confirmed by the inspection processing unit 63A will be described. When the storage battery information is the lighting continuation time, the threshold value is a predetermined arbitrary value. For example, the threshold value is set to 20 minutes, 30 minutes, or 60 minutes, which is the time stipulated by the Building Standards Act or the Fire Service Act. Further, the determination unit 63C acquires the possible lighting continuation time from the storage unit 52, and determines that the storage battery 51 is usable when the acquired lighting continuation time is greater than the threshold value.

The writing section 63D writes the storage battery information obtained by the inspection processing section 63A on the storage battery 51 into the storage section 52. At this time, the writing section 63D may write the information while in contact with the storage section 52, or may transmit and write the information in a non-contact manner.

The acquisition unit 63E acquires storage battery information from the storage unit 52 and sends it to the determination unit 63C. At this time, the acquisition unit 63E may acquire the storage battery information while in contact with the storage unit 52, or may receive and acquire the storage battery information in a non-contact manner.

The status confirmation unit 63F has a function of confirming the usability status of the storage battery 51 housed in the main body 2. The status confirmation unit 63F causes the acquisition unit 63E to acquire storage battery information from the storage unit 52, and causes the determination unit 63C to compare the storage battery information and a threshold value to determine whether the storage battery 51 is usable, and informs the notification unit 64 to be described later. The notification corresponding to the determination of whether or not the storage battery 51 can be used is made.

The notification unit 64 is one or a plurality of monitoring LEDs, and is used to notify the user of the inspection result and whether or not the storage battery 51 can be used, depending on the lighting state of the monitoring LED. The notification unit 64 notifies the determination result of whether the storage battery 51 can be used, which is obtained by using the storage battery information acquired by the acquisition unit 63E from the storage unit 52 by the status confirmation unit 63F. Although it has been described that the notification unit 64 is a monitor LED, it is not limited to this, and may be one that can display a segment display or a liquid crystal display. It may also be something that is sent as data to an external device.

The inspection switch 65 is one or more switches, and is operated to inspect the storage battery 51 or to notify whether or not the storage battery can be used. When the inspection switch 65 is pressed, it operates according to various inspection modes to be described later.

The light receiving section 66 receives an operation signal sent wirelessly from a terminal such as a remote controller (not shown). The light receiving unit 66 may receive a signal that causes the inspection processing unit 63A to inspect the storage battery 51. The light receiving section 66 may receive a signal that causes the state checking section 63F of the control device 61 to perform the operation.

FIG. 5 is a diagram illustrating modes that can be executed in the lighting device 1 according to the first embodiment. Next, four modes of the lighting device 1 according to the first embodiment: (a) regular lighting mode, (b) emergency lighting mode, (c) manual inspection mode, and (d) automatic inspection mode will be explained.

The regular lighting mode (a) is a mode in which power is supplied from a commercial power source and is in a normal state. The charging circuit 62 charges the storage battery 51 by supplying power to the storage battery 51 from a commercial power source. At this time, the lighting circuit 61 may supply power from the commercial power source to the light source section 42 to cause the light source section 42 to emit light.

The emergency lighting mode (b) is a state in which the supply of power from the commercial power source has stopped, and is an emergency situation in which power is not supplied to the lighting device 1 from the commercial power source installed outside the lighting device 1 due to a power outage, disconnection, etc. It is the mode in the state of time. The emergency lighting mode causes the charging circuit 62 to stop charging the storage battery 51 when the power supply from the commercial power supply stops, and causes the lighting circuit 61 to supply power from the storage battery 51 to the light source section 42 to turn on the light source section 42. let At this time, the storage battery 51 is discharged with the light source section 42 acting as a load.

The manual inspection mode (c) is a mode in which the inspection processing section 63A inspects the storage battery 51 while the inspection switch 65 is operated. Here, the manual inspection mode is not limited to the inspection switch 65, and the inspection processing section 63A may be caused to perform the inspection by the light receiving section 66 receiving a signal to start inspection.

The automatic inspection mode (d) is a mode in which an inspection is automatically performed using the inspection interval time, which is the time measured since the storage battery 51 receives power supply from the commercial power source, as a condition for starting an elapsed inspection. The inspection interval time is a predetermined time. When the time calculated by the clock section 63B exceeds the inspection interval time, the lighting device 1 causes the inspection treatment section 63A to inspect the storage battery 51 even if the inspection switch 65 is not pressed. Here, the inspection interval time is, for example, six months or one year. The inspection interval time is not limited to six months or one year, but may be any time.

In the manual inspection mode, an inspection is performed by the administrator's operation, and the determination of whether or not the storage battery 51 can be used is confirmed. However, since the frequency of inspection depends on the administrator, if the inspection interval is long, there is a concern that the storage battery 51 may not be replaced at the appropriate replacement time. The automatic inspection mode can suppress such concerns, and automatically inspects the storage battery 51 on a regular basis.

In the lighting device 1, the time during which the light source section 42 can be lit continuously by the storage battery 51 changes depending on the amount of charge of the storage battery 51 and the state of deterioration of the storage battery 51. Trickle charging is performed as a charging method for the storage battery 51, and the power of the storage battery 51 is controlled so that it is always in a fully charged state. However, when the storage battery 51 deteriorates, even if it is in a fully charged state, the time during which it can continue to be lit tends to shorten with elapsed time. Therefore, in order to check the deterioration status of the storage battery 51, the lighting device 1 periodically checks whether the light source section 42 can be lit for a prescribed lighting time or longer. The administrator of the lighting device 1 replaces the storage battery 51 when deterioration of the storage battery 51 is recognized, and manages and maintains the light source section 42 in a state where it can be lit for a prescribed lighting time or longer.

FIG. 6 is a flowchart regarding the inspection operation of the lighting device 1 according to the first embodiment. Next, the inspection function of the lighting device 1 will be explained. In addition, as a premise at the time of starting the flowchart in FIG. 6, it is assumed that the user performs an operation using the inspection switch 65 or the light receiving section 66 to start the operation of the inspection processing section 63A. Examples of operations for starting the operation of the inspection processing section 63A include pressing a switch for operating the inspection processing section 63A among the inspection switches 65 or causing the light receiving section 66 to receive a signal for operating the inspection processing section 63A. .

In step S101, the inspection processing unit 63A causes the charging circuit 62 to stop supplying power from the commercial power source to the storage battery 51.

After completing the process in step S101, the process advances to step S102. In step S102, the inspection processing unit 63A causes the lighting circuit 61 to supply power from the storage battery 51 to the light source unit 42, thereby lighting the light source unit 42. The storage battery 51 is discharged by the light source section 42 acting as a load. At this time, the clock section 63B starts clocking at the same timing as the lighting of the light source section 42 starts.

After completing the process in step S102, the process advances to step S103. In step S103, the inspection processing unit 63A acquires the voltage of the storage battery 51.

After completing the process in step S103, the process advances to step S104. In step 104, the inspection processing unit 63A determines whether the voltage of the storage battery 51 is lower than the discharge reference voltage, which is a voltage that allows the light source unit 42 to light up. If it is determined in step S104 that the voltage of the storage battery 51 is lower than the discharge reference voltage (step S104, YES), the process advances to step S105. At this time, it is determined that the light source section 42 cannot be lit. If it is determined in step S104 that the voltage of the storage battery 51 is equal to or higher than the discharge reference voltage (step S104, NO), the process in step S103 is performed again. At this time, it is determined that the light source section 42 can be lit continuously.

If it is determined in step S104 that the voltage value of the storage battery 51 is such that the light source section 42 cannot be lit (S104, YES), the process proceeds to step S105. In step S105, the inspection processing unit 63A stops the lighting circuit 61 from supplying power from the storage battery 51 to the light source unit 42, and ends the lighting of the light source unit 42. At this time, the timer 63B ends the timer that has been started since the light source 42 turns on, and obtains the possible lighting continuation time which is the storage battery information.

After completing the process in step S105, the process advances to step S106. In step S106, the inspection processing unit 63A causes the charging circuit 62 to supply power from the commercial power source to the storage battery 51, and starts charging the storage battery 51.

After completing the process in step S106, the process advances to step S107. In step S107, the inspection processing unit 63A causes the writing unit 63D to write the possible lighting continuation time, which is storage battery information, into the storage unit 52.

FIG. 7 is a flowchart regarding the operation of determining and notifying whether or not the storage battery 51 of the lighting device 1 can be used according to the first embodiment. Next, the determination and notification of whether or not the storage battery 51 can be used will be described using the storage battery information stored in the storage unit 52 of the lighting device 1, which is the possible lighting continuation time. It is assumed that the flowchart in FIG. 7 is started when the user performs an operation using the inspection switch 65 or the light receiving section 66 to start the operation of the status confirmation section 63F. Examples of operations for starting the operation of the status confirmation section 63F include pressing a switch for operating the status confirmation section 63F among the inspection switches 65 or causing the light receiving section 66 to receive a signal for operating the status confirmation section 63F. . Note that the start of the flowchart in FIG. 7 is not limited to the operation of the inspection switch 65 or the light receiving section 66, and may be performed after the inspection flowchart in FIG. 6 is completed.

In step S201, the state confirmation unit 63F causes the acquisition unit 63E to acquire the possible lighting continuation time, which is storage battery information, from the storage unit 52, and transmits it to the determination unit 63C.

After completing the process in step S201, the process advances to step S202. In step S202, the determination unit 63C determines whether the possible lighting continuation time, which is storage battery information, is equal to or greater than a threshold value. If the determination unit 63C determines in step S202 that the possible lighting continuation time, which is the storage battery information, is greater than or equal to the threshold value (S202, YES), the process proceeds to step S203. At this time, the storage battery 51 is determined to be usable. If the determination unit 63C determines in step S202 that the possible lighting continuation time, which is the storage battery information, is less than the threshold value (S203, NO), the process proceeds to step S204. At this time, the storage battery 51 is determined to be unusable.

If it is determined in step S202 that the possible lighting continuation time, which is the storage battery information, is longer than the threshold value (S202, YES), the process advances to step S203. In step S203, the notification unit 64 provides notification indicating the determination result that the storage battery 51 is usable.

If it is determined in step S202 that the possible lighting continuation time, which is the storage battery information, is shorter than the threshold (S202, NO), the process advances to step S204. In step S204, the notification unit 64 provides notification indicating the determination result that the storage battery 51 is unusable.

Next, the effects of the lighting device 1 of the first embodiment will be explained.

The lighting device 1 of the first embodiment includes a main body 2 that is attached to an attached part, and a storage unit 52 that stores a storage battery 51 and storage battery information indicating the state of the storage battery 51, and can be stored in the main body 2. It includes a certain storage battery unit 5 and a control device 63 that acquires storage battery information stored in the storage section 52. Therefore, when the storage battery unit 5 is replaced, the lighting device 1 can acquire storage battery information from the storage unit 52 of the storage battery unit 5 without performing a new inspection.

In addition, the lighting device 1 of the first embodiment includes a determination unit 63C that determines whether or not the storage battery 51 can be used by comparing the storage battery information acquired from the storage unit 52 and a threshold value for determining whether or not the storage battery 51 can be used. and a notification unit 64 that notifies the determination result of the determination unit 63C. Therefore, in the lighting device 1, when the storage battery unit 5 is replaced, the notification unit 64 can notify the determination result of whether or not the storage battery 51 can be used without performing a new inspection.

Further, the control device 63 of the lighting device 1 according to the first embodiment includes a writing unit 63D that inspects the storage battery 51 and writes the inspection result into the storage unit 52 as storage battery information of the storage battery 51. Therefore, in the lighting device 1, since storage battery information, which is information for determining whether or not the storage battery 51 can be continuously used, is written in the storage section 52 attached to the storage battery unit 5, the storage battery unit 5 is not attached to the main body 2. Even if there is no storage battery 51, the storage battery information of the storage battery 51 can be confirmed.

Further, in the lighting device 1 of the first embodiment, the storage unit 52 of the storage battery unit 5 is a storage medium such as an IC chip or an RFID tag, and the control device 61 acquires storage battery information from the storage unit 52 in a non-contact manner. do. Therefore, in the lighting device 1, the storage battery information can be communicated between the storage section 52 and the control device 61 without performing work such as connecting wires between the storage section 52 and the control device 61. It becomes easy to attach and detach the storage battery unit 5 to and from the storage battery unit 5.

Next, a first modification of the first embodiment will be described.

Inspection of the lighting device 1 according to the first embodiment is performed by the inspection processing unit 63A, which stops the supply of power from the commercial power source to the storage battery 51 and causes the storage batteries 51 to supply power from the storage battery 51 to the light source unit 42. Although it has been described that the light source section 42 is turned on, the object to which power is supplied from the storage battery 51 is not limited to the light source section 42 but may also be the pseudo load 44 provided in the light source unit 4.

Since the pseudo load 44 generates heat when it is supplied with electric power, the light source section 42 is used for inspection in the automatic inspection mode of the emergency lighting equipment in which the light source section 42 emits light when the power supply from the commercial power supply is stopped. This prevents the user from misperceiving that there is a power outage or abnormality due to the light being emitted.

The pseudo load 44 can increase the power supplied from the storage battery 51 to more than the power consumed in the emergency lighting mode. At this time, since the storage battery 51 consumes power more quickly than the inspection when the light source section 42 is used as a load, the inspection time can be shortened. Here, the power supplied to the pseudo load 44 may be arbitrarily set, and the relationship between the supplied power and the inspection time is, for example, when the supplied power is twice the power supplied to the light source section 42. The inspection time may be set to be half of the prescribed lighting time of the light source section 42.

Next, a second modification of the first embodiment will be described.

Although it has been explained that the threshold value of the illumination device 1 according to the first embodiment is stored in the determination unit 63C of the control device 63, the target to be stored is not limited to the determination unit 63C, and may be stored in the storage unit 52. Good too. At this time, the acquisition unit 63E acquires the storage battery information and the threshold value from the storage unit 52, and the determination unit 63C compares the acquired storage battery information and the threshold value to determine whether the storage battery is usable.

In the lighting device 1 of Modification 2, since the storage battery information and the threshold value are stored in the storage unit 52 of the storage battery unit 5, a threshold value suitable for the storage battery 51 can be set even if the threshold value of the storage battery unit 5 to be replaced is different. The determining unit 63C can determine whether or not the storage battery 51 can be used.

Next, a third modification of the first embodiment will be described.

Although it has been explained that the storage battery information of the lighting device 1 of the first embodiment is the possible lighting continuation time, it is not limited to the possible lighting continuation time, but includes the voltage transition when the storage battery 51 is discharged, the number of inspections of the storage battery 51, and the storage battery 51. The information may be information indicating the state of the storage battery 51 obtained by inspecting the storage battery 51 by the inspection processing unit 63A, such as the voltage at the time of charging or the charging time of the storage battery 51. At this time, the threshold value stored in the determination unit 63C is arbitrarily determined to be a value corresponding to the storage battery information.

Furthermore, the storage battery information of the lighting device 1 of the first embodiment is not limited to information obtained when the storage battery 51 is inspected by the inspection processing unit 63A, but also the information that has passed since the storage battery 51 was charged by the commercial power source. Regardless of the time, the temperature history around the storage battery 51, or the number of times the storage battery 51 supplies power to the light source unit 42 to turn on the light source unit 42, etc., the storage battery 51 is attached to the main body 2. It may also be information that is displayed.
