  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. First, a first embodiment of the present invention will be described.

  FIG. 1 is a schematic block diagram of a lighting device showing a first embodiment of the present invention. The lighting device 1 includes a discharge lamp 2 as a light source, a high-frequency lighting circuit 3 as a lighting circuit, a light receiving unit 4, a fire signal input unit 5, a notification sound generating unit 6, a control unit 7, an emergency power source 8, and a night light as a light source. 9 and the input voltage detector 10 and the like.

  The discharge lamp 2 is, for example, a fluorescent lamp, and is lit at high frequency by the high frequency lighting circuit 3. The high-frequency lighting circuit 3 includes a rectifier circuit 11 and an inverter circuit unit 12, and the input side is connected to a commercial AC power supply Vs via a wall switch 13. The rectifier circuit 11 converts the AC power supply voltage from the commercial AC power supply Vs into a DC voltage and inputs it to the inverter circuit unit 12. The inverter circuit unit 12 is configured by a known circuit such as a half-bridge type inverter circuit or a resonance circuit, and is configured to convert the DC voltage into a high-frequency voltage. The high-frequency lighting circuit 3 lights one discharge lamp 2 in the figure, but can also light a plurality of discharge lamps 2.

  The light receiving unit 4 includes a light receiving element (not shown) that receives a remote control signal transmitted from the remote control device, and is configured to demodulate the remote control signal and send it to the control unit 7. The remote control signal is a signal for switching the lighting state of the discharge lamp 2 and the night light 9 as light sources.

  The fire signal input unit 5 is connected to a fire detection device 14 that detects heat rays, smoke, and the like. The fire detection device 14 detects the occurrence of a fire by detecting heat rays or smoke, and sends out a fire detection signal. The fire signal input unit 5 is configured to send the fire detection signal to the control unit 7.

  The notification sound generating unit 6 is formed of a buzzer, for example, and generates a notification sound according to a voltage signal from the control unit 7. For example, when a voltage signal having a predetermined width is supplied, “P” is produced, and when a predetermined voltage signal is intermittently supplied, “P, P” is produced.

  The control unit 7 includes an internal power supply (not shown), and supplies DC power to the light receiving unit 4, the fire signal input unit 5, the input voltage detection unit 10, the fire detection device 14, etc., and operates them constantly. It is in a state. The internal power supply is charged by, for example, the output voltage of the rectifier circuit 11 of the high-frequency lighting circuit 3 when the wall switch 13 is turned on.

  When the remote control signal is input from the light receiving unit 4, the control unit 7 controls the inverter circuit unit 12 of the high frequency lighting circuit 3 to turn on, turn off, or dimm the discharge lamp 2 in accordance with the remote control signal. A signal is sent and a control signal for turning on or off the night light 9 is sent to the switching circuit 15. Here, when the nightlight 9 is turned on, the nightlight 9 is connected between the outputs of the rectifier circuit 11 by the switching circuit 15. The night light 9 is turned on by applying a DC voltage obtained by rectifying the AC power supply voltage of the commercial AC power supply Vs.

  The control unit 7 sends a voltage signal (control signal) having a predetermined width to the notification sound generating unit 6 when a remote control signal is input. The notification sound generator 6 generates a predetermined notification sound, for example, “pea”. Thereby, switching of the lighting state of the discharge lamp 2 and the nightlight 9 by operation of the remote control device is notified.

  When the fire detection signal is input from the fire signal input unit 5, the control unit 7 is configured to send, for example, an intermittent voltage signal having a predetermined width to the notification sound generation unit 6. The control unit 7 continuously sends out the voltage signal until the input of the fire detection signal is stopped. The notification sound generating unit 6 continuously generates, for example, “Peep” as the notification sound corresponding to the fire detection signal. Thereby, the occurrence of a fire is notified.

  In addition, the control unit 7 sends a control signal to the switching circuit 15 to light the nightlight 9. At this time, the control unit 7 connects the nightlight 9 between the outputs of the rectifier circuit 11 according to the presence or absence of the AC power supply voltage from the commercial AC power supply Vs input to the high-frequency lighting circuit 3 detected by the input voltage detection unit 10. Or connected to the emergency power source 8. Thereby, even if a power failure occurs when a fire occurs, the night light 9 is turned on.

  The emergency power supply 8 is made of a battery, for example, and is charged by a charging device 16 to which the output voltage of the rectifier circuit 11 is input as an input power supply. And when a fire breaks out and the power is cut off, the night light 9 is connected.

  The night light 9 is made of, for example, a bean ball. Here, since the nightlight 9 is turned on by the output voltage (DC voltage) of the rectifier circuit 11 or the DC voltage of the emergency power supply 8, a light emitting diode (LED) may be used.

  The input voltage detection unit 10 detects the AC power supply voltage of the commercial AC power supply Vs input to the high-frequency lighting circuit 3 on the input side of the rectifier circuit 11. The control unit 7 rectifies the AC power supply voltage when the fire detection signal is input from the fire signal input unit 5 and the input voltage detection unit 10 detects the AC power supply voltage. When the input voltage detector 10 does not detect the AC power supply voltage, the emergency power supply 8 controls the nightlight 9 to be lit.

  The lighting circuit includes the emergency power supply 8, the opening / closing device 15, the charging device 16 and the like in addition to the high-frequency lighting circuit 3.

  Next, the operation of the first embodiment of the present invention will be described.

  When the remote control signal transmitted from the remote control device is received by the light receiving unit 4, the control unit 7 controls the high-frequency lighting circuit 3 or the opening / closing device 15 in accordance with the remote control control signal, and the discharge lamp 2 or the nightlight 9 The lighting state is switched and a voltage signal having a predetermined width is transmitted to control the notification sound generating unit 6 so that a predetermined notification sound, for example, “pea” corresponding to the remote control signal is generated from the notification sound generating unit 6. By the generation of the predetermined notification sound, the operator of the remote control device can confirm the switching of the lighting state of the discharge lamp 2 or the nightlight 9.

  Then, when the fire detection device 14 detects a fire with heat rays or smoke and the fire signal input unit 5 inputs a fire detection signal from the fire detection device 14, the control unit 7 intermittently sends a voltage signal of a predetermined width. Then, the notification sound generator 6 is controlled to generate a notification sound corresponding to the fire detection signal from the notification sound generator 6, for example, “pea, peep”, and according to the detection state of the AC power supply voltage by the input voltage detector 10. Then, the switchgear 15 is controlled to turn on the night light 9. As long as the fire detection signal is input to the fire signal input unit 5, the control unit 7 continues the generation of the notification sound from the notification sound generation unit 6 and the lighting of the night light 9. This continuous notification sound can recognize that a fire has occurred. Moreover, since the notification sound according to the fire detection signal is different from the predetermined notification sound according to the remote control signal, it is possible to immediately recognize the occurrence of the fire. Further, the illumination by the night light 9 can promptly shift to an appropriate evacuation action even at night.

  As described above, the notification sound generation unit 6 notifies both the predetermined notification sound according to the remote control signal and the notification sound according to the fire detection signal, so that the lighting device 1 is a new fire notification device or the like. It is not necessary to provide an additional function. As a result, the lighting device 1 can suppress the increase in size and cost as much as possible, and the marketability is improved.
