  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. An overall schematic configuration of a lighting apparatus according to an embodiment of the present invention will be described with reference to FIG. The illuminating device 11 such as a guide light or an emergency light rectifies and smoothes the AC power from the commercial power source 10 into a DC power source, smoothes the DC power source, and is rectified and smoothed by the rectifying and smoothing circuit 12. A DC / DC switching circuit 13 that generates and outputs a DC voltage of a predetermined voltage value from a DC power supply, and a battery 23 that is an emergency power supply by a DC power supply of a predetermined voltage value output from the DC / DC switching circuit 13 A battery charging circuit 14 for charging, a switching circuit 15 for supplying power from the battery 23 as lamp lighting power, and a push-pull inverter circuit 16 for lighting the lamp by a DC power source having a predetermined voltage value from the DC / DC switching circuit 13. The lamp 17 lit by the push-pull inverter circuit 16, the DC / DC switching circuit 13 A lamp monitor comprising a microprocessor 18 to which DC power of a predetermined voltage value is supplied via a diode 19, an inspection switch 20 connected to the microprocessor 18, and an LED element whose lighting is controlled by the microprocessor 18. 21 and a charge monitor 22.

  The microprocessor 18 monitors and controls the operation state of the DC / DC switching circuit 13, the battery charging circuit 14, the switching circuit 15, and the push-pull inverter circuit 16, and detects the operation of the inspection switch 20. The lighting control of the lamp monitor 21 and the charging monitor 22 is performed.

  The illuminating device 10 having such a configuration normally rectifies and smoothes the alternating current from the commercial power supply 10 in the rectifying / smoothing circuit 12 and charges the battery in the DC / DC switching circuit 13. The push-pull inverter circuit 16 A direct current power source for lighting the lamp 17 and a driving power source for driving the microprocessor 18 are generated and output via the. The battery 23 is charged via the battery charging circuit 14 by the direct current power source for charging the battery from the DC / DC switching circuit 13, the lamp 17 is turned on via the push-pull inverter circuit 16 by the direct current power source for lighting, The microprocessor 18 is driven by a driving DC power source.

  In the lighting device 11, when an emergency occurs and the power from the commercial power supply 10 is cut off in a state where the lamp 17 is turned on with the power from the commercial power supply 10, the microprocessor 18 10 is detected, the switching circuit 15 is switched, the power from the battery 23 is supplied to the push-pull inverter circuit 16 to keep the lamp 17 on, and the microprocessor 18 is also driven by the power from the battery 23. To do.

  When the power supply from the commercial power supply 10 is recovered, the microprocessor 18 detects the recovery of the commercial power supply 10 and switches the switching circuit 15 to stop the power supply from the battery 23 to the push-pull inverter circuit 16. Based on the power from the commercial power supply 10, the lamp 17 is normally turned on and the battery charging circuit 14 is charged by the DC power generated in the rectifying / smoothing circuit 12 and the DC / DC switching circuit 13, and the The processor 18 itself is also operated by a driving DC power supply. The microprocessor 18 detects the operation of the battery charging circuit 14 and turns on the charge monitor 22 during the charging operation of the battery 23. Further, the microprocessor 18 detects the disconnection of the lamp 21 by the lamp current supplied from the push-pull inverter circuit 16 to the lamp 17, and when the disconnection of the lamp 17 is detected, the lamp monitor 21 is turned on and displayed.

  The microprocessor 18 includes a lighting control by the battery 23 when the commercial power supply is interrupted due to the above-described emergency, a switching control from the lighting of the battery to the lighting by the commercial power supply when the commercial power is restored, and detection of the charging operation of the battery 23 In addition to the display and the detection display of the disconnection of the lamp 17, there is a sequence for controlling the lighting inspection including the periodic inspection according to the present invention by operating the inspection switch 20.

  The lighting inspection sequence will be described. As described above, the lighting inspection is legally obligated to temporarily turn on the lamp 17 for a short time with the power from the battery 23 as an emergency power source and to turn on the lamp for a predetermined period set in advance. There is a regular inspection. These lighting inspections are executed by operating the inspection switch 20. The inspection switch 20 is turned on when pressed or lowered, and is turned off when released or released. In the description of the embodiment, a switch that is turned on when pressed and turned off when released is described as an example.

  In this lighting inspection temporary inspection sequence, when the inspection switch 20 is pressed on, the microprocessor 18 detects that the inspection switch 20 is pressed on, and stops the DC power supply output from the DC / DC switching circuit 13. Then, the switching circuit 15 is switched so that the power from the battery 23 is supplied to the push-pull inverter circuit 16, and the lamp 17 is lit with the power from the battery 23. When the pressing on of the inspection switch 20 is released, the microprocessor 18 operates the DC / DC switching circuit 13 and also stops the supply of power from the battery 23 to the normal commercial power supply 10. The lamp 17 is turned on again. That is, in this temporary inspection, the lamp 17 is turned on by the electric power from the battery 23 while the inspection switch 17 is pressed down.

  Therefore, if the operation on state of the inspection switch 20 is continuously maintained for a predetermined period set in advance for the periodic inspection, the periodic lighting can be turned on. However, as described above, the pressing of the inspection switch 20 is continued to be complicated. Misoperations of work, temporary inspection and periodic inspection occur.

  Therefore, the present invention sets the standby state for carrying out the periodic inspection by pressing and holding the inspection switch 20 for a preset time, and presses the inspection switch 20 again within the preset time from the standby state. The periodic check operation starts.

Such a periodic inspection sequence according to the present invention will be described with reference to FIG. In the normal lighting mode (step S1) in which the lamp 17 is lit by the lighting device 11 with the power from the commercial power source 10, the microprocessor 18 monitors the state of the inspection switch 20, and the inspection switch 20 is pressed. (Step S2). If it is determined in this step S2 that the inspection switch 20 has been pressed, the switching circuit 15 is switched, and it is confirmed whether or not it is a battery lighting switch that turns on the lamp 17 with the power from the battery 23 (step S3). . If it is determined that the battery lighting switching is not the battery lighting switching as a result of the confirmation determination of the battery lighting switching in step S3, it is determined whether or not the pressing-on state of the inspection switch 20 is continued (step S4). If it is determined in step S4 that the check switch 20 is kept pressed down, the process returns to step S3. If it is determined that the check switch 20 is not pressed on continuously, the process returns to the normal lighting mode ( Step S5).

  If it is determined in step S3 that the battery switch is switched by pressing the check switch 20, the check switch 20 is continuously pressed for t1 seconds, which is a preset time. (Step S6). As a result of the determination in step S6, if the pressing-on time of the inspection switch 20 is within t1 seconds, it is determined whether the pressing-on of the inspection switch 20 has been released (step S7). As a result of the determination in step S7, when it is determined that the pressing on of the inspection switch 21 is released, the normal lighting mode is returned (step S8), and when it is determined that the pressing on of the inspection switch 20 is not released, The process returns to step S6.

  If it is determined in step S6 that the pressing of the inspection switch 20 has continued for t1 seconds, it is determined that the operation for performing periodic inspection is performed, and the lamp monitor 21 and the charge monitor are set as standby states for periodic inspection. The 22 LED elements are lit in a blinking manner according to preset blinking conditions. It is made to blink by the blink pattern 1 of the LED elements of the lamp monitor 21 and the charge monitor 22 indicating the regular inspection standby state (step S9). The blinking pattern 1 indicating the standby state of the periodic inspection in step S9 is, for example, that either one of the lamp monitor 21 and the charge monitor 22 is turned on for 0.2 seconds, turned off for 0.2 seconds, or is charged with the lamp monitor 21. The blinking pattern is such that the monitor 22 is simultaneously turned on for 0.2 seconds and turned off for 0.2 seconds.

  When the lamp monitor 21 and the charging monitor 22 are blinked by the blinking pattern 1 indicating the periodic inspection standby state in step S9, it is determined whether the pressing on of the inspection switch 20 is released (step S10). In step S10, it is determined that the inspection switch 20 is continuously pressed down even though the lamp monitor 21 and the charge monitor 22 indicating the regular inspection standby state are blinking and lit in step S9. Then, it is determined whether or not the pressing-on state of the inspection switch 20 continues for a preset time t2 seconds. (Step S11). That is, it is determined whether or not the inspection switch 20 has been pressed for a time exceeding t1 seconds in step S6 and further exceeding t2 seconds. If it is determined that the press-on of the inspection switch 20 has not exceeded t2 seconds, the process returns to step S10. In step S11, when it is determined that the pressing on of the inspection switch 20 is continued for t2 seconds, the periodic inspection standby state is stopped, and the blinking display of the lamp monitor 21 and the charging monitor 22 is stopped. (Step S12). When the periodic inspection standby state in step S12 is canceled, it is determined whether the pressing on of the inspection switch 20 is released (step S13), and when the pressing on of the inspection switch 20 is released, the mode returns to the normal lighting mode (step S13). S14).

  If it is determined in step S10 that the pressing on of the inspection switch 20 is released, it is determined whether or not the inspection switch 20 for operating the periodic inspection is pressed on again (step S15). If it is determined in step S15 that the inspection switch 20 has not been pressed down again, it is determined whether the state in which the inspection switch 20 has not been pressed down again continues for a preset time t3 seconds (step S16). ). In step S16, if the time during which the inspection switch 20 is not pressed down again does not continue for t3 seconds, the process returns to step S15. If it continues for t3 seconds, it is determined that the periodic inspection is not performed and the normal lighting mode is restored. (Step S17).

  If it is determined in step S15 that the inspection switch 20 has been pressed down again, it is determined that the periodic inspection operation has started, the periodic inspection is started, and the lamp monitor 21 and the charge monitor 22 are blinked in accordance with the blinking pattern 2. To display the operation status of the periodic inspection. For example, the lamp monitor 21 is turned on for 0.2 seconds so that the blinking pattern 2 of the lamp monitor 21 and the charging monitor 22 indicating the periodic inspection operation state is different from the blinking pattern 1 in the periodic inspection standby state described above. The charging monitor 22 is turned off / on for 0.2 seconds while the lamp monitor 21 is off for 0.2 seconds while the charging monitor 22 is turned on / off for 0.2 seconds.

  Along with the blinking of the blinking pattern 2 indicating the operation state of the periodic inspection in step S18, the operation of the periodic inspection is started. In this periodic inspection operation, it is determined that the lamp 17 is not lit due to disconnection or the like based on the lamp current of the lamp 17 detected by the push-pull inverter circuit 16 (step S19). The periodic check is mainly to check the life of the battery 23 of the battery charging circuit 14. For this reason, in general, the life is determined by monitoring the power supplied from the battery 23.

  However, since the battery 23 supplies the lighting power of the lamp 17 and the power for driving the microprocessor 18, even if the lamp 17 is disconnected, the microprocessor 18 exists as a load of the battery 23. The battery life is determined by the power supplied to the microprocessor 18, and the battery 23 is not correctly determined.

  Therefore, when the disconnection of the lamp 17 is detected by the lamp current detected by the push-pull inverter circuit 16, the start of the periodic inspection operation is stopped and the mode is returned to the normal lighting mode (step S20).

  If it is determined in step S19 that no non-lighting due to disconnection of the lamp 17 or the like is detected, in order to start a periodic inspection operation, the pressing switch is turned on again from the state where the inspection switch 20 is pressed down again in step S15. It is determined whether it has been released (step S21). When the pressing on of the inspection switch 20 is released in step S21, a periodic inspection operation is started. In the state in which the periodic inspection operation is being executed by releasing the pressing on of the inspection switch 20 in step S21, it is determined whether the inspection switch 20 has been pressed on again in order to stop the periodic inspection operation (step S22). . If it is determined in step S22 that the inspection switch 20 is not depressed again in the periodic inspection operation state, the process returns to step S21. If it is determined that the inspection switch 20 is depressed again, the periodic inspection is performed. The operation state is stopped and the periodic inspection determination is canceled (step S23). If the determination by the periodic inspection operation is canceled in step S23, the mode returns to the normal lighting mode (step S24).

As described above, the lighting device 10 according to the present invention sets the standby state of the periodic inspection when the predetermined time inspection switch 20 is depressed and turned on when performing the periodic inspection, and informs the standby state of the periodic inspection. The lamp monitor 21 and the charge monitor 22 are blinked in the blink pattern 1. When the inspection switch 20 is pressed again within a predetermined time from the standby state of the periodic inspection, the periodic inspection is in an operation state, and the lamp monitor 21 and the charge monitor 22 are blinked in order to notify the operation state of the periodic inspection. Blink in pattern 2. If the inspection switch 20 is not depressed again within a preset time from the periodic inspection standby state, the periodic inspection standby state is canceled.

  As a result, when the operator operates the inspection switch 20 with the intention of general lighting inspection, when the operator presses the switch for a relatively long time and presses it beyond a preset time, the operation state of the periodic inspection is immediately performed. Instead, the operator can notify the operator of the operation error by temporarily setting the standby state for the periodic inspection and blinking the standby state using the lamp monitor 21 and the charge monitor 22. In addition, if the inspection switch 20 is not operated again within a preset time from the standby state of the periodic inspection, the periodic inspection operation is not performed and the normal lighting is resumed. It is possible to prevent the inspection from being performed. Further, when the operation state of the periodic inspection is set, the non-lighting state of the lamp 17 is detected and the execution of the periodic inspection is determined, so that the load of the battery 23 serving as an emergency power source is only the microprocessor 18. It is possible to avoid the determination of the battery life due to a very light state.

  Further, the configuration of the embodiment of the present invention makes it difficult for the lighting device to be in a state not intended by the operator, so that the temporary inspection switch and the periodic inspection switch can be shared, so that an increase in cost can be suppressed. Moreover, since the state of the lighting mode can be confirmed from the outside by the combination of the blinking state of the lamp abnormality display LED and the battery charge display LED, it is not necessary to provide a special display unit. Furthermore, since the lamp abnormality indicator LED and the battery charge indicator LED are provided on the lower side of the main body of the lighting device, the inspection operation by the operator of the guide light fixture usually installed at a high place such as a ceiling or a wall is visually recognized. It becomes easy to do.

  By the way, the periodic inspection of the lighting device described above is to determine whether the lamp can be lit with the electric power from the battery 23 as an emergency power source for a predetermined period, and is a life determination of the battery 23. For this reason, at the end of the life of the battery 23, the power capacity of the battery may be lost within a predetermined period of the periodic inspection. In this case, it is necessary to notify the replacement of the battery, stop the periodic inspection, and return to the normal lighting which is turned on with power from the commercial power source.

  For this reason, the voltage of the battery 23 is detected during periodic inspection, and when the voltage drops below a predetermined voltage value, the periodic inspection is interrupted and switched to normal lighting in which the lamp is lit with electric power from the commercial power source. The forced return function is required.

  Providing this forcible return function in the lighting device complicates the configuration of the lighting circuit of the lighting device and may increase the cost. For this reason, there is a need for an illumination device that can detect a decrease in battery voltage during periodic inspection and can be switched to normal lighting with a simple configuration. Therefore, a lighting device having a forced recovery function with a simple configuration will be described with reference to FIG.

  This illuminating device includes a rectifier circuit 25 that rectifies commercial power supply 10 into direct current, a primary circuit of a transformer 27 provided at both ends of a smoothing capacitor 26, a series circuit of a power supply control IC 35, and a photo that controls driving of the power supply control IC 35. A first diode 28 and a second diode 29 for extracting voltages of different values from the secondary side of the transistor 30a and the transformer 27; the outputs of the first diode 28 and the second diode 29; The first smoothing capacitor 31 and the second smoothing capacitor 32 provided between the base end of the secondary side, the output of the first diode 28, the connection point of the first smoothing capacitor 31, and the two of the transformer 27 A series circuit of a resistor 33, a fourth diode 34, and a battery 35 provided between the base ends on the secondary side, and a connection between the output terminal of the second diode 29 and the second smoothing capacitor 32 The inverter circuit 16 provided between the point and the base end of the secondary side of the transformer 27, the lamp 17 lit by the inverter circuit 16, the output terminal of the fourth diode 34 and the connection point of the battery 35 and the A switching transistor 36 provided between the output terminals of the second diode 29, a third diode 37 connected to the connection point between the output terminal of the second diode 29 and the second smoothing capacitor 32, and a third smoothing capacitor 38, a microprocessor 18 provided at both ends of the third smoothing capacitor 38, a connection point between the output end of the third diode 37 and the third smoothing capacitor 38, and the microprocessor 18 A series circuit of a resistor 39 and a photodiode 30b, a resistor 40 provided in parallel with the resistor 39 and the photodiode 30b, and this resistor It consists 40 and test switch 20 provided between the reference end of the connection point and the second smoothing condenser 38 of the microprocessor 18.

  The transformer 27 and the power supply control IC 35 constitute the DC / DC switching circuit 13 described above. The first diode 28 and the first smoothing capacitor 31 connected to the secondary side of the transformer 27 rectify and smooth the charging voltage of the battery 35, and in a charging circuit including the resistor 33 and the fourth diode 34. The battery 35 is charged. The second diode 29 and the second smoothing capacitor 32 rectify and smooth the lighting voltage for lighting the lamp 17 via the inverter circuit 16. The inverter circuit 16 controls the lighting of the lamp 17, and normally the lamp 17 is lit by the voltage from the second diode 29 and the second smoothing capacitor 32, the commercial power supply 10 is cut off, and the second When the outputs of the diode 29 and the second smoothing capacitor 32 are cut off, the lamp 17 is turned on by the power from the battery 35.

  The third diode 37 and the third smoothing capacitor 38 generate a driving potential for the microprocessor 18. The phototransistor 30a and the photodiode 30b constitute a photocoupler. When the photodiode 30b is turned on, the phototransistor 30a is turned on, and the driving of the power supply control IC 35 is stopped.

  The microprocessor 18 controls the switching transistor 36 so as to supply power from the battery 35 to the inverter circuit 16 when the commercial power supply 10 is shut off or the inspection switch 20 is operated, or the microprocessor 17 controls the lamp 17. Various control and monitoring of the illumination device such as disconnection monitoring of the lamp 17 is performed by the lamp current supplied to the lamp.

  In the lighting device having such a configuration, during normal lighting, the commercial power supply 10 is rectified and smoothed, the battery 35 is charged by the potential generated by the first diode 28 and the first smoothing capacitor 31, and the second diode 29 and the second smoothing capacitor 32 turn on the lamp 17 via the inverter circuit 16, and the potential generated by the third diode 37 and the third smoothing capacitor 38 causes the micro The processor 18 is operating. During the normal lighting, the microprocessor 18 turns off the switching transistor 36 and turns off the photodiode 30b.

  When checking the lighting from the normal lighting state, when the check switch 20 is pressed down, the microprocessor 18 detects the operation of the check switch 20 and turns on the photodiode 30b and turns on the switching transistor 36. When the photodiode 30b is turned on, the phototransistor 30a is turned on, the operation of the power supply control IC 35 is stopped, and the commercial power supply 10 is cut off. On the other hand, when the switching transistor 36 is turned on, the power from the battery 35 is applied to the microprocessor 18 via the switching transistor 36, the inverter circuit 16, and the third diode 37 and the third smoothing capacitor 38. Then, the lamp 17 is turned on and the microprocessor 18 is driven by the power of the battery 35.

  As described above, when the periodic inspection operation is detected by the operation of the inspection switch 20 in the microprocessor 18 and the periodic inspection is performed, if the capacity of the battery 35 is consumed and the power is exhausted, the lamp 17 Is turned off, and power for driving the microprocessor 18 is also lost, so that the microprocessor 18 becomes inoperative. When the microprocessor 18 is stationary, the photodiode 30b and the switching transistor 36 are turned off. When the photodiode 30b is turned off, the phototransistor 30a is also turned off, and the power supply control IC 35 is restarted. Thereby, the lighting of the lamp 17 can be restarted via the inverter circuit 16 and the battery 35 can be charged based on the direct current obtained by rectifying and smoothing the commercial power supply 10.

  That is, the power supply control IC 35 is controlled by the photocoupler 30 by utilizing the fact that the microprocessor 18 cannot be operated due to the capacity of the battery 35 being lost without constantly monitoring the capacity of the battery 35 at the time of lighting inspection. With a simple configuration, normal lighting by the commercial power supply 10 can be quickly restored.
