By the way, this kind of lighting equipment can exhibit a function as an emergency lighting equipment that performs emergency lighting on the surroundings for a predetermined time in the event of a power failure. However, the lighting fixture itself could not exert the function of notifying the user of the fire prevention object such as a building of the occurrence of a fire (the occurrence of a specific event). Further, conventionally, in order to notify the elderly or the hearing impaired of the occurrence of a fire as soon as possible, for example, a light alarm device may be installed separately from the lighting equipment.

However, installing both an emergency lighting fixture and a light alarm device on a fireproof object has a problem that it leads to an increase in installation cost.

The present invention has been made in view of the above reasons, and an object of the present invention is to provide a lighting fixture and a lighting system capable of reducing installation costs while maintaining reliability regarding lighting in the event of a power failure and notification of the occurrence of a specific event. And.

The luminaire according to one aspect of the present invention includes a light source, a detection unit, a communication unit, and a control unit. The detection unit detects a power failure of the power supply. The communication unit receives a detection signal indicating detection of a specific event other than the power failure from the communication device. The control unit controls the lighting state of the light source. When the detection unit detects the power failure, the control unit controls the light source to be continuously lit in the first lighting state. Further, when the communication unit receives the detection signal, the control unit controls the light source to blink and light in a second lighting state different from the first lighting state. The luminaire further includes a flag receiving unit. The flag receiving unit receives a first discrimination flag for determining the validity and invalidity of the first lighting state and a second discrimination flag for determining the validity and invalidity of the second lighting state. When the detection unit detects the power failure, the control unit determines whether or not the light source is turned on in the first lighting state according to whether the first determination flag is valid or invalid. When the communication unit receives the detection signal, the control unit determines whether or not the light source is turned on in the second lighting state according to whether the second discrimination flag is valid or invalid.

The lighting system according to one aspect of the present invention includes the luminaire and the communication device capable of transmitting the detection signal indicating the detection of the specific event to the luminaire.

The present invention has an advantage that the installation cost can be reduced while maintaining the reliability of lighting at the time of a power failure and notification of the occurrence of a specific event.

(1) Overview The following embodiments are merely one of various embodiments of the present invention. The following embodiments can be variously modified according to the design and the like as long as the object of the present invention can be achieved.

The lighting fixture 1 of the present embodiment is configured to perform emergency lighting, for example. As shown in FIG. 3, the luminaire 1 charges the emergency power supply 12 with electric power from an external power source (for example, a commercial AC power source 9) during normal use (the light source 10 is not lit), and the emergency power source 1 is used in an emergency. The light source 10 is turned on by the electric power from 12 to perform emergency lighting. In other words, the lighting fixture 1 is, for example, a lighting fixture dedicated to emergency lighting that does not perform regular lighting during regular use.

As an example, the lighting fixture 1 is configured to be directly attached and fixed to the ceiling (or the ceiling of a landing of stairs or the like) in a passage in a building such as an office building. However, the luminaire 1 may be configured to be embedded in the ceiling, or may be configured to be fixed to a wall or the like in addition to the ceiling. Further, the lighting fixture 1 may be directly attached by a hanging bolt of a ceiling material (construction material). In addition to office buildings, lighting equipment 1 includes theaters, movie theaters, public halls, amusement parks, complex facilities, restaurants, department stores, schools, hotels, inns, hospitals, homes for the elderly, kindergartens, libraries, museums, museums, underground malls, etc. It may be installed in a station, an airport, a condominium (apartment), a detached house, or the like.

Here, as shown in FIG. 3, the luminaire 1 includes a light source 10, a detection unit (power failure detection circuit 113), a communication unit 115, and a control unit (control circuit 114). The power failure detection circuit 113 detects a power failure of the power supply (for example, a commercial AC power supply 9). The communication unit 115 is configured to receive a detection signal indicating detection of a specific event other than a power failure from an external communication device (receiver 4). The control circuit 114 is configured to control the lighting state of the light source 10. In the following, it is assumed that a "specific event" other than a power failure is a fire as an example. However, the "specific event" may be an emergency disaster such as an earthquake or a tsunami, or an invasion of a suspicious person, in addition to a fire.

In the present embodiment, the control circuit 114 controls the light source 10 to be turned on in the first lighting state when the power failure detection circuit 113 detects a power failure. Further, when the communication unit 115 receives the detection signal, the control circuit 114 controls the light source 10 to be turned on in a second lighting state different from the first lighting state. The "first lighting state" is, for example, continuous lighting. The "second lighting state" is, for example, blinking lighting.

Further, the lighting system 100 of the present embodiment includes a lighting fixture 1 and a communication device (receiver 4) capable of transmitting a detection signal indicating detection of a specific event (fire) to the lighting fixture 1. In the present embodiment, as described above, the "specific event" is a fire as an example. Therefore, for convenience of explanation, the lighting system 100 is configured as an automatic fire alarm system including at least one lighting fixture 1. Suppose.

According to this configuration, the control circuit 114 of the luminaire 1 controls the lighting of the light source 10 in different lighting states depending on whether a power failure occurs or a specific event occurs. Therefore, the lighting fixture 1 and the lighting system 100 do not need to install a light alarm device separately from the lighting fixture 1, for example, or the number of light alarm devices can be reduced. As a result, it is possible to reduce the installation cost while maintaining the reliability of lighting in the event of a power failure and notification of the occurrence of a specific event.

(2) Details (2.1) Overall configuration Hereinafter, the lighting system 100 of the present embodiment will be described in detail with reference to FIGS. 1 to 4.

For example, three lighting fixtures 1 are installed on the ceiling of a passage on each floor of a building (for example, the first floor to the fourth floor). FIG. 1 shows only the lighting fixtures 1A to 1C installed on the first floor and the lighting fixtures 1D to 1F installed on the second floor for convenience of explanation. The receiver 4 is installed in a disaster prevention center or the like of a building.

Further, as shown in FIG. 1, the lighting system 100 has a plurality of fire detection systems 8 (two in FIG. 1, that is, only the first floor and the second floor like the lighting fixture 1) so as to correspond to each floor of the building. (Illustrated). Each fire detection system 8 has a repeater 3, a plurality of fire detectors 2 (three in FIG. 1), a transmitter 5, and a terminating resistor 7. Each fire detector 2 is installed, for example, on the ceiling of the aisle on the corresponding floor. The repeater 3 is housed in, for example, a distributed processing panel installed on the corresponding floor. The transmitter 5 is attached to a wall around the passage, a distributed processing board, or the like. In the present embodiment, as an example, the caution area is set for each floor of the building, but the present embodiment is not particularly limited.

As shown in FIG. 1, the lighting system 100 further includes an audio device 6. The sound device 6 includes, for example, a bell and a motor for ringing the bell. The receiver 4 rings the sound device 6 in the event of a fire. The lighting system 100 may further include emergency broadcasting equipment having a voice alarm function. Emergency broadcasting equipment will be installed at disaster prevention centers and the like. When a fire breaks out, the receiver 4 can notify the entire building of the fire by sound or voice through the emergency broadcasting equipment by emergency broadcasting. Further, the lighting system 100 may be able to control the fire door of the smoke prevention equipment when a fire occurs.

The fire detection system 8 is not an essential component of the lighting system 100. The lighting system 100 may be in a form applied to existing fire detectors and transmitters. Further, when the "specific event" is other than a fire, the lighting system 100 may include a system other than the fire detection system 8. For example, when the "specific event" is the intrusion of a suspicious person, the lighting system 100 may include a crime prevention system that detects the intrusion of the suspicious person. Further, the repeater 3 may be omitted.

The receiver 4 and the plurality of repeaters 3 are electrically connected to each other by, for example, a set of two (two-wire type) first communication lines L1 so that they can communicate with each other. Each repeater 3 is electrically connected to the corresponding three fire detectors 2 and the transmitter 5 by a pair of two (2-wire type) second communication lines L2. Further, a terminating resistor 7 is electrically connected to the end of the second communication line L2 installed on each floor (the end on the opposite side of the repeater 3). The terminating resistor 7 is not an essential configuration and may be omitted. For example, the transmitter 5 may be installed as a terminal.

The receiver 4, the repeater 3, and the fire detector 2 are configured to communicate with each other by an R-type (Record-type) communication method as an example. More specifically, the receiver 4, the repeater 3, and the fire detector 2 communicate with each other via the first communication line L1 by a time division multiplexing transmission method. As the communication protocol of the time division multiplex transmission system, for example, the communication standard of NMAST (registered trademark) can be adopted. The receiver 4 transmits a bipolar (± 24V) time-division multiplex signal as a transmission signal to the first communication line L1, and the data is transmitted by pulse width modulation. A part of the plurality of fire detectors 2 may be a P-type detector or a general detector, and in this case, the repeater 3 is communicated by a P-type (Proprietary-type) communication method.

Each fire detector 2 is, for example, a detector that senses smoke and / or heat. When each fire detector 2 detects the occurrence of a fire, it outputs a signal notifying the occurrence of a fire (hereinafter referred to as a fire alarm) to the second communication line L2. As an example, each transmitter 5 has a push button, and when the push button is pushed, a fire alarm is output to the second communication line L2. In short, each transmitter 5 notifies the corresponding repeater 3 of the occurrence of a fire by manually operating the push button when a person in the building finds a fire. When the repeater 3 receives the fire report, the repeater 3 transmits the fire report to the receiver 4 via the first communication line L1.

When the receiver 4 receives a fire alarm from at least one fire detector 2 or the transmitter 5 among the plurality of fire detectors 2, the receiver 4 performs an operation of notifying the occurrence of a fire (hereinafter, referred to as a first operation). The first operation referred to here is, for example, notifying the whole building of a fire by sound or voice through a sound device 6, or causing a fire to a facility outside the building (for example, a fire station) via a telecommunication line. It is an operation to make a report.

Further, the above-mentioned first request signal and second request signal may also be transmitted by an operation input from the user to the operation unit 45 in addition to the periodic transmission.

The receiver 4 uses a commercial AC power source 9 (see FIG. 1) as a main power source. The receiver 4 generates a DC voltage having a predetermined voltage value (for example, 24V) from a voltage (AC voltage having an effective value of 100V) supplied from the AC power supply 9 via the power supply line L0 (see FIG. 1). The receiver 4 may use a private power generation facility or the like as a main power source instead of the AC power source 9, or may use both the AC power source 9 and the private power generation facility as the main power source. The receiver 4 supplies electric power for the operation of each repeater 3 by applying a DC voltage between the pair of electric wires constituting the first communication line L1. The receiver 4 further includes a backup power supply 46 using a storage battery so that power for operation can be secured when the power supply from the AC power supply 9 is stopped (during a power failure). The receiver 4 automatically switches the power supply source from the main power supply to the standby power supply 46 when the main power supply fails, and automatically switches from the standby power supply 46 to the main power supply when the main power supply is restored.

The DC power supply circuit 110 is composed of, for example, a self-excited switching power supply circuit such as a ringing choke converter. Convert to a DC voltage lower than the effective value. The charging circuit 111 operates when power is supplied from the AC power supply 9, and is configured to flow a constant charging current from the DC power supply circuit 110 to the emergency power supply 12. The lighting circuit 112 is configured to convert the direct current supplied from the emergency power supply 12 into a constant current and supply it to the light source 10. The power failure detection circuit 113 is configured to detect a power failure of the AC power supply 9 from the output voltage of the DC power supply circuit 110 and notify the control circuit 114. Hereinafter, the state in which the power failure detection circuit 113 detects a power failure is referred to as a “first detection state”.

The monitor lamp 116 has, for example, an LED chip that emits green light, and emits light by a charging current supplied from the charging circuit 111 to the emergency power supply 12. As shown in FIG. 4, the lamp cover of the monitor lamp 116 is exposed through the through hole 132 of the cover 130. The communication unit 115 is connected to the third communication line L3 and is configured to be able to receive a detection signal from the receiver 4. Hereinafter, the state in which the communication unit 115 receives the detection signal from the receiver 4 is referred to as a “second detection state”.

The light receiving unit 121 has a light receiving element. The light receiving unit 121 is configured to receive a radio signal using infrared rays as a communication medium, demodulate the transmission frame from the received radio signal, and pass it to the control circuit 114. The light receiving element is arranged so as to face the through hole 133 of the cover 130. This wireless signal is transmitted from a wireless transmitter 14 (see FIG. 4) operated by a worker who performs periodic inspection work of the lighting fixture 1 which is an emergency lighting fixture. Periodic inspection is carried out for the lighting fixture 1 which is an emergency lighting fixture at intervals specified by law, and the lighting circuit 112 is forcibly operated to keep the light source 10 in the lighting state for a specified time or longer. The purpose is to confirm that it is done.

Here, the control circuit 114 operates the charging circuit 111 and stops the lighting circuit 112 (turns off the light source 10) when the state of the luminaire 1 does not correspond to both the first detection state and the second detection state. It is configured to let you. The control circuit 114 is configured to stop the charging circuit 111 and operate the lighting circuit 112 when the state of the luminaire 1 corresponds to at least one of the first detection state and the second detection state. In particular, the control circuit 114 controls the lighting circuit 112 so that the light source 10 is turned on in the first lighting state when the state of the lighting fixture 1 corresponds to the first detection state. Here, the first lighting state is, for example, continuous lighting. On the other hand, the control circuit 114 controls the lighting circuit 112 so that the light source 10 is turned on in a second lighting state different from the first lighting state when the state of the lighting fixture 1 corresponds to the second detection state. Here, the second lighting state is, for example, blinking lighting. In short, the lighting circuit 112 is configured to be able to switch between continuous lighting, blinking lighting, and extinguishing according to an instruction from the control circuit 114.

The blinking light is preferably light that blinks at a predetermined blinking frequency. The blinking frequency is the frequency at which the light blinks. The blinking frequency is, for example, 0.5 Hz to 2 Hz, and as an example, 1 Hz. When the blinking frequency is 0.5 Hz, the blinking cycle is 2 seconds. When the blinking frequency is 1 Hz, the blinking cycle is 1 second. When the blinking frequency is 2 Hz, the blinking cycle is 0.5 seconds.

The control circuit 114 controls the lighting circuit 112 so that the light source 10 is turned on in different lighting states depending on whether a power failure occurs or a fire occurs. Therefore, it is not necessary to install an optical alarm device separately from the lighting fixture 1, or the number of optical alarm devices can be reduced, and the installation cost can be maintained while maintaining the reliability of lighting in the event of a power failure and notification of the occurrence of a fire. Can be reduced. Further, since the optical alarm device is unnecessary or the number of optical alarm devices can be reduced, it is possible to prevent the design (appearance) of the ceiling, wall, etc. of the building from being impaired.

When the first push button switch 117 is pushed or the transmission frame is received from the light receiving unit 121, the control circuit 114 stops the charging circuit 111 and operates the lighting circuit 112 to perform a periodic inspection operation. Configured to do. However, the control circuit 114 is configured to operate the lighting circuit 112 for several seconds when the second push button switch 118 is pressed, then stop the lighting circuit 112 again and operate the charging circuit 111. Will be done. In the inspection operation, it is desirable that the lighting circuit 112 sequentially executes continuous lighting and blinking lighting so that both continuous lighting and blinking lighting of the light source 10 can be confirmed.

In the present embodiment, the first operating member (not shown) for pressing the push button of the first push button switch 117 is arranged so as to face the through hole 134 (see FIG. 4). The first operating member is housed in the instrument main body 13 without protruding outward from the through hole 134, and is pushed by the tip of a tool such as a screwdriver. As shown in FIG. 4, the second operating member 122 for pressing the push button of the second push button switch 118 is arranged so as to face the through hole 135. The second operating member 122 projects outward from the through hole 135 and is pushed by a human finger.

By the way, in the present embodiment, when the state of the luminaire 1 corresponds to the second detection state, the control circuit 114 regardless of whether or not it corresponds to the first detection state (regardless of whether or not a power failure is detected). , The light source 10 is configured to be turned on in the second lighting state. Therefore, it is possible to promptly notify the residents in the building of the occurrence of a fire that requires quicker evacuation action than a power outage.

(2.5) Priority reception unit and flag reception unit The lighting device 11 of the lighting fixture 1 further includes a priority reception unit 119 and a flag reception unit 120, as shown in FIG. The priority reception unit 119 is configured to receive the priority of fire and power failure. The flag receiving unit 120 has a first discrimination flag for determining the validity and invalidity of the first lighting state (continuous lighting) and a second discrimination flag for determining the validity and invalidity of the second lighting state (blinking lighting). And are configured to accept. However, in the present embodiment, the light receiving unit 121 functions as the priority receiving unit 119 and the flag receiving unit 120.

That is, by transmitting a wireless signal including information on the priorities of fire and power failure from the wireless transmitter 14 to the light receiving unit 121, these priorities can be registered in the luminaire 1. .. Similarly, by transmitting a radio signal including information about the first discrimination flag and the second discrimination flag from the wireless transmitter 14 to the light receiving unit 121, it is possible to register these discrimination flags in the lighting fixture 1. It has become. The control circuit 114 has a non-volatile memory such as EEPROM, and when the light receiving unit 121 receives the above priority and discrimination flags, these are stored in the memory. The third address information, which is the unique address information of the lighting fixture 1 itself described above, is also stored in this memory.

When the control circuit 114 both detects a power failure and receives a detection signal within a predetermined period (for example, within a few minutes), the light source 10 corresponds to the higher priority of fire and power failure. It is controlled so that it is lit in the lit state.

Further, when the power failure detection circuit 113 detects a power failure, the control circuit 114 determines whether or not the light source 10 is turned on in the first lighting state according to whether the first discrimination flag is valid or invalid. Further, when the communication unit 115 receives the detection signal, the control circuit 114 determines whether or not the light source 10 is turned on in the second lighting state according to whether the second discrimination flag is valid or invalid.

It is desirable that the priority and the discrimination flag are set by the builder at the time of construction of the lighting fixture 1, for example. Since the above-mentioned priority and discrimination flag can be set individually for each luminaire 1, for example, they are set so as to be appropriately different depending on the place where the target luminaire 1 is installed. May be good. For example, for the lighting fixture 1 installed on the ceiling such as a passage and an emergency staircase in a building, the power failure may be set to have a higher priority than the fire. Further, for the lighting fixture 1 installed on the wall or the like in the building, the fire may be set to have a higher priority than the power failure.

The priority reception unit 119 and the flag reception unit 120 may be provided separately from the light receiving unit 121. The priority receiving unit 119 and the flag receiving unit 120 may be configured by, for example, a DIP switch provided so as to be exposed from the cover 130, and the above-mentioned priority and discrimination flag may be set by turning on / off the DIP switch. ..

Further, the communication unit 115 may function as the priority reception unit 119 and the flag reception unit 120. In short, instead of the wireless transmitter 14, the above priority and discrimination flags may be transmitted from the receiver 4 through the third communication line L3. That is, the builder may be able to set the above-mentioned priority and discrimination flag of each luminaire 1 by the input operation of the operation unit 45 of the receiver 4.

(2.6) Description of operation regarding priority The operation regarding the priority of fire and power failure will be described below. Here, for example, it is assumed that the priorities are set for the three lighting fixtures 1A to 1C installed on the first floor as shown in Table 1 below. For example, when the installer inputs an operation to the light receiving unit 121 of the lighting fixture 1A so that the priority of the power failure is high, the installer inputs the operation input to the memory of the control circuit 114 as the priority of the power failure. For example, the numerical information of "1" is stored. At this time, for example, numerical information of "0" is stored in the memory of the control circuit 114 as the priority of the fire (that is, "1" has a higher priority than "0"). Further, when the builder inputs the operation of the wireless transmitter 14 to the lighting fixture 1B so that the priority of the fire is high, the memory of the control circuit 114 has "1" as the priority of the fire. Numerical information of "0" is stored as the priority of the power failure. On the other hand, it is assumed that the builder did not set the priority of fire and power failure for the luminaire 1C. That is, in the memory of the control circuit 114 of the luminaire 1C, "0" remains stored as the initial value set at the time of manufacturing the luminaire 1C for any priority.

Here, it is assumed that a fire occurs first and a power failure occurs several minutes later (when both the detection signal is received and the power failure is detected within a predetermined period). The lighting fixtures 1A to 1C turn on the light source 10 in the second lighting state (blinking lighting) in response to the occurrence of a fire. After that, when the lighting fixture 1A detects the occurrence of a power failure, the priority of the power failure is set high, so that the light source 10 is switched from the second lighting state to the first lighting state (continuous lighting) and turned on. On the other hand, even if the lighting fixture 1B detects the occurrence of a power failure, the light source 10 is continuously turned on in the second lighting state because the priority of the fire is set high. Since the lighting fixture 1C has no priority setting, as described in the column of "(2.4) Lighting fixture", the second lighting state is prioritized regardless of the presence or absence of a power failure. That is, even if the lighting fixture 1C detects the occurrence of a power failure, the light source 10 is continuously turned on in the second lighting state.

By setting the priority in this way, it is possible to give priority to the emergency lighting for a power failure for one lighting fixture 1 and to give priority to the notification for the occurrence of a fire for another lighting fixture 1. Therefore, for example, when the lighting fixture 1 is installed on the ceiling such as a passage and an emergency staircase, priority is given to emergency lighting, and when the lighting fixture 1 is installed on a wall, notification of the occurrence of a fire is given. Can be prioritized. As a result, it is possible to differentiate the priority between the provision of emergency lighting and the notification of the occurrence of a fire according to the installation location.

(2.7) Description of Operation Regarding Discrimination Flags Hereinafter, operations relating to the first discrimination flag and the second discrimination flag will be described. Here, for example, it is assumed that the discrimination flags are set for the six lighting fixtures 1A to 1F installed on the first floor to the second floor as shown in Table 2 below. In the "numerical information in the memory" of Table 2, the numerical information on the left corresponds to the numerical information of the first discrimination flag, and the numerical information on the right corresponds to the numerical information of the second discrimination flag.

For example, when the installer directs the wireless transmitter 14 toward the light receiving unit 121 of the lighting fixture 1A and inputs an operation so that the first discrimination flag becomes effective, the memory of the control circuit 114 of the lighting fixture 1A is filled with the operation input. For example, numerical information of "0" is stored as the first discrimination flag. Further, when the builder inputs an operation so that the second discrimination flag becomes invalid, numerical information of, for example, "1" is stored in the memory of the control circuit 114 of the lighting fixture 1A as the second discrimination flag. ..

When the builder inputs the operation of the wireless transmitter 14 to the luminaire 1B so that the first discrimination flag becomes invalid, the numerical information of "1" is stored in the memory of the control circuit 114 of the luminaire 1B. Is remembered. Further, when the builder inputs an operation so that the second discrimination flag becomes effective, the numerical information of "0" is stored in the memory of the control circuit 114 of the lighting fixture 1B.

When the builder inputs the operation of the wireless transmitter 14 to the luminaire 1C and the luminaire 1D so that both the first discrimination flag and the second discrimination flag are valid, the memory of these control circuits 114 Stores numerical information of "0" for both flags.

When the builder inputs the operation of the wireless transmitter 14 to the luminaire 1E so that both the first discrimination flag and the second discrimination flag are invalid, the memory of the control circuit 114 of the luminaire 1E is stored. , Numerical information of "1" is stored for both discrimination flags.

It is assumed that the builder did not set the first discrimination flag and the second discrimination flag on the lighting fixture 1F. In this case, "0" is still stored in the memory of the control circuit 114 of the lighting fixture 1F for both discrimination flags as the initial value set at the time of manufacturing the lighting fixture 1F.

Here, it is assumed that a power failure occurs. For the lighting fixtures 1A, 1C, 1D and 1F in which the first discrimination flag is effectively set, that is, the numerical information of the first discrimination flag in the memory of the control circuit 114 is "0", the light source 10 is the first. Lights in the lighting state (continuous lighting). On the other hand, for the lighting fixtures 1B and 1E in which the first discrimination flag is set to invalid, the light source 10 remains off even if a power failure occurs.

Further, it is assumed that a fire has occurred following the power failure within the above-mentioned predetermined period. Since the second discrimination flag is set to invalid (numerical information is "1") in the lighting fixture 1A that has been continuously lit, the control circuit 114 continuously lights the light source 10 in the first lighting state (continuous lighting). Turn on with. Further, since the second discrimination flag is set to valid (numerical information is "0") for the lighting fixtures 1C, 1D and 1F that have been continuously lit, the control circuit 114 of the lighting fixtures 1C, 1D and 1F has a control circuit 114. Read the priority stored in the memory. If the priority of fire is set higher than the priority of power failure, the control circuit 114 switches the light source 10 from the first lighting state to the second lighting state (blinking lighting) and turns it on. If the fire priority is set lower than the power failure priority, the control circuit 114 continuously turns on the light source 10 in the first lighting state.

Since the second discrimination flag is set to valid (numerical information is "0") for the lighting fixture 1B that has been turned off, the control circuit 114 of the lighting fixture 1B turns the light source 10 from the off state to the second lighting state (the light source 10 is turned off). Switch to (blinking lighting) and turn it on. Further, since the second discrimination flag is set to invalid (numerical information is "1") in the lighting fixture 1E that has been turned off, the control circuit 114 of the lighting fixture 1E continuously turns off the light source 10. Leave it as it is.

When a setting is made so as to cause a contradiction between the first discrimination flag and the second discrimination flag and the priority, the lighting fixture 1 may be provided with a display unit for notifying that fact. .. Alternatively, the lighting fixture 1 may transmit to that effect to the receiver 4, and the receiver 4 may notify the fact through the display unit 44. The contradiction mentioned here is, for example, that the first discrimination flag corresponding to the power failure is invalid and the second discrimination flag corresponding to the fire is invalid even though the priority of the power failure is set higher than the priority of the fire. Is enabled.

By setting the validity / invalidity of the discrimination flag in this way, for example, in a lighting space where a relatively large number of lighting fixtures 1 are installed, when a power failure occurs or a fire occurs for all the lighting fixtures 1. Waste such as lighting can be eliminated. That is, it is possible to reduce power consumption.

The priority reception unit 119 and the flag reception unit 120 are not essential components for the lighting fixture 1, and these may be omitted. Alternatively, the luminaire 1 may include only one of the priority reception unit 119 and the flag reception unit 120. Further, the information regarding the priority and the determination flag stored in the memory of the control circuit 114 is merely an example, and is not limited to the numerical information of “0” and “1”.

(3) Modification examples The following are some modifications. Hereinafter, the above-described embodiment will be referred to as a “basic example”. The modified examples described below can also be applied in combination with the above-mentioned basic examples as appropriate.

In the basic example, the first lighting state is continuous lighting and the second lighting state is blinking lighting, but the present invention is not limited to this, and for example, even if the emission color of the light source 10 is changed between the first lighting state and the second lighting state. good. That is, the light source 10 may have, for example, an LED chip that emits red light, in addition to the LED chip that emits blue light described above. In this case, the control circuit 114 provides an LED chip that lights the light source 10 so that the light source 10 emits normal white light in the first lighting state and emits light of a color different from the white light in the second lighting state. It may be controlled to switch to the lighting circuit 112.

In the basic example, the luminaire 1 does not perform regular lighting during normal use, that is, is a luminaire dedicated to emergency lighting, but this is not the case. The lighting fixture 1 both charges the emergency power supply 12 and lights the light source 10 (normal lighting) with the power from the AC power supply 9 during normal use, and lights the light source 10 with the power from the emergency power supply 12 during emergency (emergency lighting). Lighting) may be configured to perform. Alternatively, for example, as shown in FIG. 5, the lighting fixture 1 includes a regular lighting device 16 that performs regular lighting with a regular light source, and an emergency lighting device 17 that performs emergency lighting with an emergency light source different from the regular light source. , And a long instrument body 18 that supports them may be provided. In this case, the emergency light source of the emergency lighting device 17 corresponds to the light source 10 of the basic example, and the control circuit for controlling the lighting state of the emergency light source of the emergency lighting device 17 corresponds to the control circuit 114 of the basic example. do.

In the basic example, the control circuit 114 of the lighting fixture 1 turns on the light source 10 with the electric power supplied from the emergency power supply 12 even when a power failure does not occur and only a fire occurs. It is controlled, but not limited to this. The control circuit 114 may be controlled to turn on the light source 10 with the electric power supplied from the commercial AC power source 9, for example, when a power failure has not occurred and only a fire has occurred.

Further, in the basic example, each lighting fixture 1 includes an emergency power supply 12, but the emergency power supply 12 is not an essential component of the lighting fixture 1 and may be omitted. In this case, in an emergency, the receiver 4 may be configured to supply the power of the backup power supply 46 to each luminaire 1 through the third communication line L3. Alternatively, only the specific luminaire 1 has an emergency power supply 12, and the specific luminaire 1 has an emergency with respect to another luminaire 1 having no emergency power supply 12 through the third communication line L3. It may be configured to supply the power of the power supply 12. However, considering the disconnection of the third communication line L3 due to a fire, it is desirable that each luminaire 1 is provided with an emergency power supply 12.

The detection unit detects a power failure of the power supply (AC power supply 9). The communication unit 115 receives a detection signal indicating detection of a specific event (for example, a fire) other than a power failure from the communication device (receiver 4). The control unit controls the lighting state of the light source 10. When the detection unit detects a power failure, the control unit controls the light source 10 to be turned on in the first lighting state. Further, when the communication unit 115 receives the detection signal, the control unit controls the light source 10 to be turned on in a second lighting state different from the first lighting state. According to the first aspect, for example, it is not necessary to install a light alarm device separately from the lighting fixture 1, or the number of light alarm devices can be reduced. Therefore, reliability regarding lighting in the event of a power failure and notification of the occurrence of a specific event It is possible to reduce the installation cost while maintaining the characteristics.

It is preferable that the luminaire 1 according to the third aspect further includes a priority receiving unit 119 for receiving the priority of a specific event and a power failure in the first aspect or the second aspect. When the control unit (control circuit 114) both detects the power failure and receives the detection signal within a predetermined period, the light source 10 corresponds to the specific event and the power failure, whichever has the higher priority. It is preferable to control the lighting in the lighting state. According to the third aspect, emergency lighting for a power failure can be prioritized for one luminaire 1, and notification for the occurrence of a specific event can be prioritized for another luminaire 1. Therefore, for example, when the lighting fixture 1 is installed on the ceiling such as a passage and an emergency staircase, priority is given to emergency lighting, and when the lighting fixture 1 is installed on a wall, a specific event occurs. Notification can be prioritized. As a result, it is possible to differentiate the priority between the provision of emergency lighting and the notification of the occurrence of a specific event according to the installation location.

It is preferable that the luminaire 1 according to the fourth aspect further includes the flag receiving unit 120 in any one of the first aspect to the third aspect. It is preferable that the flag receiving unit 120 receives a first discrimination flag for determining the validity and invalidity of the first lighting state and a second discrimination flag for determining the validity and invalidity of the second lighting state. When the detection unit (power failure detection circuit 113) detects a power failure, the control unit (control circuit 114) determines whether or not the light source 10 is turned on in the first lighting state according to whether the first discrimination flag is valid or invalid. do. Further, when the communication unit 115 receives the detection signal, the control unit determines whether or not the light source 10 is turned on in the second lighting state according to whether the second determination flag is valid or invalid. According to the fourth aspect, for example, in a lighting space in which a relatively large number of lighting fixtures 1 are installed, all the lighting fixtures 1 are illuminated at the time of a power failure or a specific event. Can be omitted. That is, it is possible to reduce power consumption.

Regarding the lighting fixture 1 according to the fifth aspect, in any one of the first aspect to the fourth aspect, the first lighting state may be continuous lighting and the second lighting state may be blinking lighting. preferable. According to the fifth aspect, the resident in the building can clearly distinguish between the notification of the occurrence of a specific event and the emergency lighting in the event of a power failure. Further, for example, when a specific event is a fire, the reliability equivalent to that of the optical alarm device can be ensured.

It is preferable that the lighting fixture 1 according to the sixth aspect further includes an emergency power supply 12 in any one of the first to fifth aspects. When the detection unit (power failure detection circuit 113) detects a power failure, the control unit (control circuit 114) preferably turns on the light source 10 with the electric power supplied from the emergency power supply 12. According to the sixth aspect, the luminaire 1 can obtain its own operating power at the time of a power failure more reliably than when it receives power from, for example, the backup power supply 46 of the receiver 4.
