(Example 2) It is a flowchart which shows the basic function of the illumination control part in Example 2 shown in FIG. 1 and FIG. It is a flowchart which shows the detail of step S144 in Example 2 shown in FIG. It is. It is a block diagram which shows Example 3 of the LED lighting system which concerns on embodiment of this invention. (Example 3) It is a flowchart which shows the basic function of the illumination control part in Example 2 shown in FIG.

  FIG. 1 is a block diagram showing Example 1 of the LED lighting system according to the embodiment of the present invention. The lighting system according to the first embodiment includes lighting fixtures 4 and 6 provided on the ceiling 2, a fire alarm 8, and a remote controller (hereinafter abbreviated as "remote controller" as appropriate) 10 for controlling them in common. In the case of implementation in a business office or the like, a number of lighting fixtures are arranged on the ceiling 2, but in FIG. 1, only two lighting fixtures are shown as representatives for simplicity. The luminaires 4 and 6 and the fire alarm 8 receive power from the power line 12. On the other hand, the remote controller 10 is battery-driven. Moreover, the lighting fixtures 4 and 6 and the fire alarm 8 communicate with the remote controller 10 by infrared wireless communication or near field radio communication as will be described later. When the remote controller 10 is fixed to a room wall or the like and is of a power line drive type, the lighting devices 4 and 6 and the fire alarm 8 communicate with the remote controller 10 by power line communication (PLC) via the power line 12. It is also possible to configure as described above.

  The LED lighting device 4 is configured to be removable from the ceiling 2 and replaceable when the lifetime ends, and has a white LED group 14 as an illumination light source. The white LED group 14 is supplied with power from the power supply unit 16 connected to the power line 12 and is dimmed by the LED control unit 18 to emit light. The power supply unit 16 supplies power of a predetermined voltage not only to the white LED group 14 but also to each part of the LED lighting device 4. The illumination control unit 20 includes a microcomputer that operates according to a reference clock 22 and a predetermined program, and instructs the LED control unit 18 to turn on / off and dimm the white LED group based on a remote control signal received by the infrared wireless communication unit 24. In addition, the life management of the LED lighting device 4 is performed. Moreover, the illumination control unit 20 has a storage unit that stores therein a microcomputer program and data necessary for processing. The wireless communication unit 24 may be configured as a short-range radio wave communication unit.

  The LED life determination unit 26 determines the life of the white LED group based on the on / off from the illumination control unit 20 to the LED control unit 18 and the dimming instruction signal, the temperature of the white LED 14 and the reference clock 22, and the result is obtained. This is transmitted to the illumination control unit 20. Further, the electrolytic capacitor life determination unit 28 determines the life of the electrolytic capacitor included in the power supply unit 16 based on the rectifying / smoothing capability of the power supply unit 16 and the reference clock 22, and transmits the result to the illumination control unit 20. If the illumination control unit 20 determines that the lifetime has expired, it instructs the LED control unit 18 to turn off the white LED group. Since the configuration of the LED lighting device 6 is the same as that of the LED lighting device 4, numbering and description in the figure are omitted.

  Although the detailed configuration of the life determination and management as described above will be described later, its significance will be described here. First of all, LED lighting devices that have a much longer life than ordinary fluorescent lamp tubes have the advantage that replacement is not necessary for a long time, but there is a high possibility that memories or records related to the previous replacement will be lost. The problem is how to manage Further, in a normal fluorescent lamp tube, a clear abnormality appears in the lighting state at the end of its life or the lighting cannot be performed, so the necessity for replacement is clearly understood. On the other hand, in the LED lighting device, the brightness is gradually lowered by long-term use, and no obvious abnormal state or unlit state occurs. Therefore, people who work or live under such lighting do not know the decrease in brightness, and may be able to fall into the result of working or living in an unhealthy environment with insufficient illuminance without realizing it. There is also sex. The above-mentioned life determination and management have the significance of measures against such a situation.

  The fire alarm 8 has a power supply unit 30 that is connected to the power line 12 and supplies power of a predetermined voltage to each part of the fire alarm 8. The power supply unit 30 may be configured as a battery-driven type. The alarm control unit 32 issues an alarm from the sound alarm unit 36 and the light alarm unit 38 at the time of abnormality based on the detection by the temperature / smoke / flame sensor 34. In addition, the wireless communication unit connected to the alarm control unit 32 transmits an abnormal state to the outside and communicates with the outside when the fire alarm device 8 is tested. The alarm control unit 32 is provided with a light receiving unit 35 that is commonly supplied with power from the power supply unit 30 for the original function of the fire alarm 8 and detects the illuminance in the room. The illuminance information in the room by the light receiving sensor 35 becomes information for automatic light control of the LED lighting devices 4 and 5 as described later. In addition, by using the light receiving unit 35 fed by the power supply unit 30 for light control on a daily basis, the power supply unit 30 of the fire alarm 8 that does not operate for a long period of time unless an abnormal state occurs is routinely used. This prevents the situation that does not work in an emergency.

  The remote controller 10 has an operation unit 42 for performing a manual operation, and the remote controller control unit 44 controls the infrared wireless communication unit 46 based on the operation of the operation unit 42, and the infrared light 48 and / or the infrared light. The light 50 is transmitted to the LED communication device 4 and / or the wireless communication unit of the LED illumination device 6, respectively. In addition, when the wireless communication part 24 and the wireless communication part 46 are comprised as a short-distance radio wave communication part, the infrared light 48 and the infrared light 50 shall be understood as a radio wave. These communication units can perform not only a one-way instruction from the remote controller 10 to the LED lighting devices 4 and 6 but also two-way communication, and the remote controller 10 receives information on the lifetime of the LED lighting devices 4 and 6. However, this can also be displayed on the display unit 52. The bidirectional communication function and the display function of the display unit 52 are also used in the test of the life determination unit. Further, the display unit 52 is used for other graphical user interfaces (GUIs) in cooperation with the operation unit 42 during normal lighting and dimming control. Furthermore, the remote controller 10 relays the illuminance information in the room from the light receiving unit 35 of the fire alarm 8 to the LED lighting devices 4 and 5 as automatic dimming information.

  The remote controller 10 is also used for testing the fire alarm 8. During the test, the remote control unit 44 instructs the wireless communication unit 46 to transmit a test instruction signal using the infrared ray 54 based on the GUI operation by the operation unit 42 and the display unit 52. The transmitted test instruction signal is received by the wireless communication unit 40 of the fire alarm 8. Based on this, the alarm control unit 32 executes a predetermined test and instructs the wireless communication unit 40 to transmit a test result signal using the infrared ray 54. The test result signal by the infrared ray 54 is received by the remote controller 10 and displayed on the display unit 52 under the control of the remote control unit 44. Such a test of the fire alarm 8 is performed in cooperation with the test of the LED lighting devices 4 and 6. Details thereof will be described later.

  FIG. 2 is a block diagram showing a detailed configuration of the LED lighting device of FIG. The same parts as those in FIG. 1 are denoted by the same reference numerals, and description thereof is omitted unless necessary. The power supply unit 16 steps down the alternating current of the power line 12 with the transformer 56 and rectifies it with the full-wave rectifier 58, smooths this with the electrolytic capacitor 60, and supplies it to the direct current power supply circuit 62. The white LED group 14, the switch element 64, and the constant current source are connected in series between the DC power supply circuit 62 and the ground. Then, the white light LED group is turned on / off and light is adjusted when the switch element 64 is turned on / off by the PWM control unit 68. The duty cycle of the PWM control by the PWM control unit 68 is given from the duty control unit 70 based on the instruction signal from the illumination control unit 20. Note that zero duty cycle means turning off.

  The non-volatile counter 72 of the LED life determination unit 26 is a reference clock 22 that is frequency-divided by the variable frequency dividing unit 76 via a gate 74 that is opened when a lighting signal (a signal other than duty zero) is output from the illumination control unit 20. Count the clock pulses from. As a result, the non-volatile counter 72 accumulates and stores the lighting time of the white LED. The non-volatile counter 72 overflows when the number of pulses corresponding to the time when the white LED group is considered to have reached the end of its lifetime (for example, the brightness when emitting light with the same input is reduced to 70% of the new time). The LED life is determined by outputting a pulse to the illumination control unit 20.

  The variable frequency division unit 76 receives the lighting signal from the illumination control unit 20, and the higher the duty cycle of the lighting signal, the higher the frequency of the output pulse and the faster the count of the non-volatile counter 72 proceeds. As a result, the larger the current energy flowing through the white LED group is, the longer the lifetime is reached. Further, a thermistor 80 is provided on the heat dissipation plate 78 of the white LED group 14 to detect the heat generation state of the white LED group 14. The variable frequency dividing unit 76 receives the temperature detected by the thermistor 80, and the higher the temperature, the higher the frequency of the output pulse, so that the count of the non-volatile counter 72 advances faster. As a result, the higher the heat generation temperature of the white LED group 14, the longer the lifetime comes.

  The comparator 82 of the electrolytic capacitor life determination unit 28 compares the divided voltage of the detection resistor 84 with the reference voltage, and the low voltage portion of the divided voltage in which the smoothing ability of the electrolytic capacitor 60 is reduced to become a pulsating state is the reference voltage. When it becomes less than, the output synchronized with the pulsating flow is generated. The counter 84 counts this and outputs the overflow pulse to the illumination control unit 20 to determine the life of the electric field capacitor. Note that a clock pulse from the reference clock 22 is input to the reset terminal of the counter 84 by the frequency divider 86. As a result, the counter 84 is periodically reset (for example, when the counter 84 overflows at 128 pulse counts, the counter 84 is reset once per second), and the pulse based on the pulsating flow from the comparator is about 1 second or less. As long as it does not continue, the counter 84 is prevented from overflowing. As a result, the life is determined when the smoothing ability of the electrolytic capacitor 60 is reliably lowered, and the noise pulse is cumulatively counted when the partial pressure of the detection resistor 84 is temporarily reduced, and the life is determined to be reached. To prevent malfunctions.

  FIG. 3 is a flowchart showing the basic functions of the illumination control unit 20 shown in FIGS. 1 and 2. The flow starts when various operation signals such as a lighting signal from the remote controller 10 or a life determination function test signal are received. When the flow starts, it is checked in step S2 whether or not a lighting signal has been received. If the lighting signal has been received, the process proceeds to step S4 to perform a life determination check process, and then proceeds to step S6. The life determination check process in step S4 is a check process for determining whether it is determined that the life of the electric field capacitor has expired or the life of the LED has been exhausted. The details will be described later.

  In step S6, it is checked whether or not the determination that the electrolytic capacitor life has been exhausted has been made as a result of the life determination check in step S4. If the determination is not made, the process proceeds to step S8 and the life in step S4 is determined. As a result of the judgment check, it is checked whether or not it has been judged that the electrolytic capacitor life has expired. If it is determined that the life of the LED is exhausted, the process proceeds to step S10, and the lighting signal confirmed to be received in step S2 is a predetermined time after the LED is exhausted and the LED lighting device is turned off. It is checked whether the lighting signal is within (for example, 30 seconds). This is for re-lighting by performing a lighting operation within a predetermined time when the LED lighting device that is lit in the immediate light-off mode described later is suddenly turned off due to the end of its life.

  If the operation does not correspond to step S10, the process proceeds to step S12, and it is checked whether or not the lighting signal confirmed to be received in step S2 is received within a predetermined time (for example, 1 second) after the previous operation. This is because it is determined that the LED has reached the end of its life, and even if the LED lighting device does not light up in a normal lighting operation, by performing a special operation of continuously operating within an interval of 1 second or less. It is for enabling lighting. If the operation corresponds to step S12, the process proceeds to step S14, and after determining that the LED has reached the end of its life, it is checked whether the operation is within a predetermined number of times (for example, five times). This is because of the convenience of use, even if the life of the LED is exhausted, it can be lit by a special operation called continuous operation, but there is a certain limit on the number of times, and the LED illuminates steadily despite the end of the life of the LED This is to prevent the operation from continuing.

  When the operation is within the predetermined number of times in step S14, the process proceeds to step S16, the operation signal reception count is incremented by one, and the process proceeds to step S18 to turn on the LED. On the other hand, if it is not determined in step S8 that the LED has reached the end of its life, the process directly proceeds to step S18, and the LED is immediately turned on. Further, if it is confirmed in step S10 that the LED is turned on within a predetermined time after the LED is turned off due to the lifetime, the process directly proceeds to step S18 to turn on the LED.

  When the LED is turned on in step S18, the process proceeds to step S20, and it is checked whether a determination signal indicating that the life of the electrolytic capacitor or the LED has expired during the lighting is generated. When a determination signal indicating that the lifetime has expired is generated, the determination result is stored in step S22 and transmitted to the remote controller 10, and the process proceeds to step S24. In step S24, when a determination signal indicating that the lifetime has expired is generated, it is checked whether or not the mode is set to immediately turn off the LED. If it is not the immediate turn-off mode, the turn-off at this point is not executed, and the process proceeds to step S26. Since the determination that the life has expired is stored in step S22, this is confirmed by the check in step S4 the next time the lighting operation is performed, and except when it corresponds to step S10 or step S12 and step S14. Cannot be lit. On the other hand, when there is no signal indicating that the life has expired in step S20, the process directly proceeds to step S26.

  In step S26, a dimming process is performed to cope with automatic or manual dimming. Details thereof will be described later. When the dimming process is completed, the process proceeds to step S28, and it is checked whether or not a turn-off signal has been received from the remote controller 10. If no turn-off signal is received, the process returns to step S20. Thereafter, steps S20 to S28 are repeated unless the turn-off signal is received and a signal indicating that the life has expired in the immediate turn-off mode is generated. Respond to changes. On the other hand, when the reception of the turn-off signal is confirmed in step S28, the process proceeds to step S30. In addition, also when reception of a lighting signal is not confirmed by step S2, it transfers to step S30.

  In step S30, it is checked whether or not a signal by various operations such as a life determination test signal and a pseudo life exhaustion reset signal described later has been received. And if reception of these signals is confirmed, various operation processing of Step S32 will be performed, and a flow will be completed. On the other hand, if reception of various operation signals is not confirmed in step S30, the flow is immediately terminated.

  Here, when it is determined in step S6 that the life of the electrolytic capacitor has been exhausted, the process proceeds to step S34, where “non-lighting” is transmitted to the remote controller 10 and the flow is immediately terminated. Compared to the case where the lifetime of the LED is exhausted, in this case, the amount of light emission is simply insufficient, and since there is no urgency, priority is given to the convenience of use for the time being. And allowed to light up again. However, when the life of the electrolytic capacitor is exhausted, considering the possibility of unforeseen circumstances such as ignition by continuing use, the difference between the LED life and the case where the life of the LED has expired as described above is repeated. There is no means for enabling lighting.

  Although related to the above, if it is not detected in step S12 that the lighting signal is within the predetermined time after the previous operation when the LED has reached the end of the life, the process proceeds to step S36, and if the continuous operation is performed, the predetermined value is obtained. A guidance display instruction signal indicating that lighting can be performed up to the number of times is transmitted to the remote controller 10, and the process proceeds to step S34. On the other hand, when it is detected in step S14 that the lighting is performed by a predetermined operation or more, the process immediately proceeds to step S34. In any case, the lighting is not executed according to the lighting operation. If it is in the immediate turn-off mode in step S24, the process proceeds to step S38 to execute the immediate turn-off of the LED, and in step S40, a guidance display indicating that the light can be turned on again if operated within a predetermined time. The instruction signal is transmitted to the remote controller 10 and the process proceeds to step S34.

  FIG. 4 is a flowchart showing details of the life determination check process in step S4 of FIG. When the flow starts, it is checked in step S42 whether there is a determination memory indicating that the life of the electrolytic capacitor has expired. If there is no memory, the process proceeds to step S44, and it is checked whether or not there is a determination memory indicating that the LED has reached the end of its life. When it is confirmed that there is this memory, the process proceeds to step S46, where the LED end-of-life determination memory in this LED lighting device is first activated and then the process proceeds to step S48.

  Next, in step S48, information on another LED lighting device is acquired via the remote controller 10, and in step S50, the presence or absence of information indicating that the LED life has expired in the other LED lighting device is checked. If there is such information, in step S52, the time stamp of the information indicating that the LED life has expired in the other LED lighting devices precedes the time stamp of the information indicating that the LED life of the LED lighting device has been exhausted. Check if it is. As a result, if the time stamp of another LED lighting device is preceded, the process proceeds to step S54, where the LED end-of-life determination memory in the own LED lighting device is first deactivated, and the flow ends.

  As described above, in the life determination check flow, as long as there is an LED lighting device whose LED has been exhausted earlier by exchanging information with other LED lighting devices in the same room, the lifetime is exhausted for the time being. The notification is left to the LED lighting device, and the LED end-of-life determination memory in its own LED lighting device is inactivated, and lighting is permitted on the assumption that the lifetime has not been exhausted. In this way, it is prevented that a plurality of LED lighting devices in the same room are turned off at the same time due to the end of the LED life, and only the one with the oldest time stamp is turned off as a representative so that the life is exhausted. Notice. Then, when an older LED lighting device is replaced and the time stamp of its own LED lighting device becomes the oldest, the determination memory that the LED has reached the end of its life is activated, and the light is turned off.

  On the other hand, when the electrolytic capacitor has reached the end of its life in step S42, safety is prioritized over the inconvenience of simultaneously turning off the plurality of LED lighting devices, and the memory indicating that the life of the electrolytic capacitor has expired in its own LED lighting device. Is always activated. If there is no memory indicating that the LED has reached the end of life in step S44, the flow is immediately terminated. If there is no information on the LED end of life in another LED lighting device in step S50, or if there is no other LED lighting device with an older LED time stamp in step S52, the self in step S46 The activation of the LED end-of-life memory of the LED lighting device is maintained and the flow is terminated.

  FIG. 5 is a flowchart showing details of the light control processing in step S26 of FIG. When the flow starts, an illuminance signal is requested to the fire alarm 8 via the remote controller 10 in step S62. In step S64, it is checked whether the response of the illuminance signal measured by the light receiving unit 35 is received from the fire alarm device 8 via the remote controller 10. If a response is received, the process proceeds to step S66 to check whether the LED lighting device 4 is set to the automatic light control mode. If it is the automatic light control mode, the process proceeds to step S68, and it is checked whether the room illuminance measured by the fire alarm 8 is equal to or greater than a predetermined value. As a result, if the room illuminance is greater than or equal to the predetermined value, the process proceeds to step S70, where the current duty signal is stored, and instead, the energy saving duty signal is output in step S72, and the process proceeds to step S74. The energy saving duty signal usually indicates a duty cycle smaller than the duty signal stored in step S70. When the room is brighter than a predetermined value and the need for assistance by lighting is low, the LED lighting device emits light. It automatically suppresses and contributes to energy saving.

  On the other hand, if it is not detected in step S68 that the room illuminance is equal to or greater than the predetermined value, the process proceeds to step S76, and it is checked whether or not the energy saving duty cycle is currently applied. If it is an energy saving duty cycle, the process proceeds to step S78, the duty signal stored before the energy saving duty cycle is applied is read and output, and the process proceeds to step S74. On the other hand, when application of the energy saving duty cycle is not detected in step S76, the process directly proceeds to step S74. Thus, when the indoor brightness is below a predetermined level, lighting is performed at a normal duty cycle, and when the energy saving duty is applied, the lighting is returned to the normal duty cycle. If it is not detected in step S66 that the automatic dimming mode is set, the process proceeds directly to step S74 without performing automatic dimming regardless of the illuminance signal responded in step S64.

  Moreover, when the response of an illuminance signal is not detected by step S64, it is thought that there exists a problem in the electric power feeding for making the light-receiving part 35 of the fire alarm 8 function. Since the light receiving unit 35 is supplied from the power supply unit 30 that is common to the original functional parts of the fire alarm 8 such as the temperature / smoke / flame sensor, if there is a problem with the power supply to the light receiving unit 35, the fire notification It is considered that there is a problem with the power supply to the original functional part of the machine 8. Therefore, when the response of the illuminance signal is not detected in step S64, the process proceeds to step S80, a message “Fire alarm power supply abnormality” is transmitted to the remote controller 10, and the process proceeds to step S74. By using the light receiving unit 35 provided in the fire alarm 8 for dimming in this way, the operation of the fire alarm having the property that it is desired not to operate for a long period of time is routinely checked. Prevent situations that sometimes do not work.

  In step S74, it is checked whether or not a manual dimming signal generated based on the operation of the operation unit 42 of the remote controller 10 has been received. If a manual dimming signal is received, the process proceeds to step S82, where a new due cycle signal based on the manual setting is output and the flow is terminated. As described above, in the dimming process, the brightness of the LED lighting device can be changed automatically or manually. However, when the room illuminance is brighter than a predetermined value in the automatic dimming mode, the energy saving duty has priority. Moreover, the fire alarm 8 is always checked by the illuminance signal regardless of the setting of the automatic light control mode.

  FIG. 6 is a flowchart showing details of various operation processes in step S32 of FIG. When the flow starts, first, in step S92, it is checked whether or not the operation signal received from the remote controller 10 is a signal for instructing a test of the life determination function. If it is a function test signal, the function of the LED life determination unit 26 is first checked in step S94. This check includes, for example, a pulse passage test from the reference clock to the variable frequency dividing unit 76 and the gate 74, a frequency division rate changing function test of the variable frequency dividing unit 76, and a non-volatile counter after temporarily saving the count value. Including 72 count progress and overflow tests.

  Further, in step S96, the function of the electrolytic capacitor life determination unit 28 is checked. This check includes, for example, a comparison function check of the comparator 82, a count progress of the counter 84, a reset and an overflow test. Based on these function check results, in step S98, it is confirmed whether or not all the life determination unit functions are normal. If there is any abnormality, the process proceeds to step S100, a pseudo state where the life of the electrolytic capacitor has expired is set, and the process proceeds to step S102. On the other hand, when it is confirmed in step S98 that all the life determination unit functions are normal, the process proceeds directly to step S102 without doing anything.

  In the above, the pseudo state of the end of the electrolytic capacitor life set in step S100 has a function of shifting the flow to step S34 when this is checked in step S6. In this case, when the life determination unit function is not normal, the LED lighting device does not light even if the lighting operation is performed. In addition, when the pseudo state of the electrolytic capacitor life expiration is checked in step S20, if it is the immediate extinguishing mode, the flow is shifted to step S38 via step S24. In this case, when the life determination unit function is abnormal, the LED lighting device that is turned on by the test operation is immediately turned off. In any case, when the LED lighting device is not turned on or off, an abnormality of the life determination unit function is notified in a form that does not cause recognition failure.

  Furthermore, in step S102, the test results of the LED and electrolytic capacitor life determination function based on the checks in steps S94 and S96 are specifically transmitted to the remote controller 10, and the process proceeds to step S104. Since the remote controller 10 displays this information on the display unit 52, the person who performed the test operation can specifically know the result. In step S92, when it is not detected that the operation signal received from the remote controller 10 is a signal for instructing the test of the life determination function, the flow directly proceeds to step S104.

  In step S104, it is checked whether or not the operation signal received from the remote controller 10 is a pseudo end of life reset signal. Then, if applicable, the process proceeds to step S106, the set electrolytic capacitor pseudo life end state is reset, and the flow is ended. On the other hand, when the received operation signal is not a pseudo life end reset signal, the flow is immediately terminated. The electrolytic capacitor pseudo-life state set in step S100 does not turn on or turns off the LED lighting device as described above, so that the cause can be understood and reset when the LED lighting device is turned on for the time being. Can be turned on. The reset signal detected in step S104 is transmitted from the remote controller 10 by manual operation for such a purpose.

  FIG. 7 is a flowchart showing functions of the remote control unit 44 shown in FIG. The flow starts when the operation unit 42 is operated to operate the LED lighting devices 4 and 6 and the fire alarm 8 or when the wireless communication unit 46 receives a signal from the LED lighting devices 4 and 6 and the fire alarm 8. When the flow starts, it is first checked in step S112 whether a lighting operation has been performed. And if it is lighting operation, it will progress to step S114, will transmit a lighting signal to the LED lighting apparatus 4 and the LED lighting apparatus 6, and will transfer to step S116. On the other hand, if the lighting operation is not detected in step S, the process directly proceeds to step S116.

  In step S116, it is checked whether or not a signal indicating “non-lighting” is received from any of the LED lighting devices 4, 6 and the like. If there is reception, the process proceeds to step S118, and the received end-of-life determination result is displayed on the display unit. Next, in step S120, it is checked whether or not a signal indicating “lighting operation guidance” is received from the LED lighting devices 4 and 6 or the like. Then, if there is a reception, the process proceeds to step S122, in which the display unit 52 is instructed to display that “the lamp can be lit if operated continuously within a predetermined time”, and the process proceeds to step S124. On the other hand, if reception of a signal for performing “lighting operation guidance” is not detected in step S120, the process directly proceeds to step S124.

  In step S124, it is checked whether or not an operation for resetting the LED illumination device is performed when the LED illumination device is not lit or extinguished due to a pseudo life exhaustion state set based on the life determination function test result. If there is, the process proceeds to step S126, and a signal for resetting the pseudo-life-out state is transmitted to the corresponding LED certification device, and the process proceeds to step S128. On the other hand, when the reset operation is not detected in step S124, the process directly proceeds to step S128.

  Further, when reception of a signal indicating “non-lighting” is not detected in step S116, the process directly proceeds to step S128. Therefore, in this case, guidance display in step S122 is not performed, and confusion due to unnecessary display can be avoided. Further, since the pseudo end of life reset operation is not checked in step S124, the function is not confused in response to an erroneous operation of the pseudo end of life reset.

  In step S128, it is checked whether or not an operation for testing the lifetime determination function of the LED lighting device has been performed. If this operation is not detected, the process proceeds to step S130 to check whether an operation for testing the fire alarm has been performed. And even if it is a case where life judgment function test operation is detected by step S128, or it is a case where fire alarm test operation is detected by step S130, all progress to step S132, LED lighting apparatus 4, 6 transmits a life determination function test signal to 6 and transmits a fire alarm test signal to the fire alarm 8. Furthermore, in step S134, the result of the function test is received from each of the LED lighting devices 4 and 6 and the fire alarm 8, and the display unit 52 displays them in parallel, and the process proceeds to step S136. On the other hand, if no test operation is detected in step S128 and step S130, the process directly proceeds to step S136.

  As described above, in the flow of FIG. 7, regardless of which test operation is performed, the LED illumination device life determination function test and the fire alarm test are always performed in pairs, and the results are displayed in parallel. It is desirable that neither the end of the life of the LED lighting device nor the fire alarm by the fire alarm normally occur for a long period of time. However, a test is indispensable for guaranteeing that it functions in an emergency. In the above configuration, even if the other test is performed without being conscious of one test, both are performed and displayed in pairs. It is meaningful to call attention to each other so that they are not neglected. Steps S128 and S130 each have a manual operation detection function. In addition, step S132 is automatically executed every time a predetermined period (for example, once every six months) has elapsed, and both test signals are transmitted. You may comprise. Also in this case, the necessity of both tests is alerted in pairs by the parallel display of both test results in step S134. In addition, since the abnormality of the power supply part of an illuminating device may cause a fire, since a fire alarm is related to the alerting | reporting by any chance as a result, both cooperation is significant.

  In step S136, it is checked whether or not “fire alarm power supply abnormality” has been received from the LED lighting devices 4 and 6. If there is a reception, the process proceeds to step S138 to display “fire alarm power supply abnormality” and then proceeds to step S140. On the other hand, if no signal reception is detected in step S136, the process directly proceeds to step S140. In step S140, it is checked whether or not there has been no operation or signal reception for a predetermined time, and if applicable, the flow ends. On the other hand, if there is any operation or signal reception within the predetermined time, the process returns to step S112, and thereafter, unless there is no operation or signal reception for the predetermined time, step S112 to step S140 are repeated.

  The various features of the present invention are not limited to the implementation in the first embodiment, and other implementations utilizing the advantages are possible. For example, in Example 1 described above, the LED or the electrolytic capacitor is not turned on to notify that the life of the LED or the electrolytic capacitor has expired, or the LED being turned on is turned off. When the life of the capacitor is exhausted, the abnormal lighting state different from the normal lighting such as blinking LED may be notified. Moreover, it is also possible to notify the two in an identifiable manner, for example, by changing the blinking cycle of the abnormal lighting state between when the LED life is exhausted and when the electrolytic capacitor life is exhausted. Further, the abnormal lighting mode of the LED when there is an abnormality in the life detection function can be made different from the abnormal lighting mode when the life of the LED or the electrolytic capacitor is exhausted, so that the functional abnormality can be notified in an identifiable manner. is there.

  Further, instead of detecting the LED life by the integrated count of the energy supply state to the LED as in the first embodiment, a light receiving unit for actually monitoring the light emission state of the LED is provided to supply the energy to the LED and from the LED. Even when the LED life is detected based on the relationship with the light emission, various features after the LED life detection of the present invention can be applied. Furthermore, the various features of the present invention related to the electrolytic capacitor life can be applied to lighting devices other than LED lighting devices such as fluorescent lighting devices.

  Furthermore, in the said Example 1, by exchanging information between other LED lighting devices as shown in FIG. 4, a plurality of LED lighting devices are turned off at the same time due to the end of the LED life in the same room. However, prevention of simultaneous turn-off due to the end of the LED life is not limited to such means. For example, the non-volatile counter 72 in FIG. 2 is regarded as the time when the lighting time of the white LED group has reached 40,000 hours (the time when the brightness when emitting light with the same input decreases to 70% of the new time). It is set to generate an overflow pulse when the number of pulses corresponding to is counted. Here, if an additional count time component is provided in the non-volatile counter 72 and the additional count time is set so as to vary randomly within about plus or minus 100 hours for each LED lighting device, the same room is shipped. Even if the plurality of LED lighting devices are turned on for the same time under the same conditions, it is not determined that the lifetime has been exhausted at the same time, and the execution of turning off is performed with the above time variation. As a result, it is possible to prevent a plurality of LED lighting devices from being turned off at the same time due to the end of the LED life in the same room, and there is sufficient time to replace the LED lighting device that has been turned off earliest. The next LED lighting device is turned off.

  FIG. 8: is a block diagram which shows the detailed structure of the LED lighting apparatus in Example 2 of the LED lighting system which concerns on embodiment of this invention. Since the entire system is basically the same as that of the first embodiment, FIG. 1 is used. Further, in FIG. 8, the same parts as those in FIG. 2 of the first embodiment are denoted by the same reference numerals, and description thereof is omitted unless necessary.

  Corresponding Example 2 in FIG. 8 differs from Example 1 in that the white LED group is configured as a divided white LED group 114, and the switch element group 116 and the constant current source group 166 are accordingly divided white LEDs. It is a point which can dim each division part of a group independently. As a result, the white LED group 114 can be turned on while part of the white LED group 114 is turned off, or can be turned on with gradation added to the brightness of the part. This is possible when the divided white LED groups of a plurality of LED lighting devices are seamlessly arranged in a line, and the boundary between the lit part and the unlit part is not the LED lighting device unit but the middle of the LED lighting device. In addition, a smooth gradation can be applied to the entire plurality of LED lighting devices arranged in a row. The PWM control unit 68 is output from the duty control unit 70 based on an instruction from the illumination control unit 120 in order to independently turn on / off the divided portions of the divided white LED group 114 or to turn on the divided portions with different brightnesses. The corresponding switch elements in the switch element group 164 are independently controlled based on the plurality of duty cycle signals. These are disclosed in Japanese Patent Application Nos. 2009-127206 and 2009-147167 by the same applicant. The various lighting functions as described above in the divided white LED group 114 provide various illumination modes during normal illumination, and are also used for performing specific notification when the life of the LED illumination device 4 is exhausted. The Details thereof will be described later.

  Moreover, Example 2 has the nightlight control part 102 controlled by the illumination control part 120, and the yellow LED 104 by which lighting / extinguishing is controlled by this. The nightlight control unit 102 turns on the yellow LED as a nightlight with low power instead of the divided white LED group 114 that is turned off at the time of sleeping or the like according to the operation of the remote controller 10. The nightlight control unit 102 and the yellow LED are used as a nightlight as described above during normal use, and are also used when performing a specific notification when the life of the LED lighting device 4 is exhausted. Details thereof will be described later. In the second embodiment, the transformer is omitted and the full-wave rectifier 58 is directly fed from the power line 12 as shown in FIG. 8, but the presence or absence of the transformer is particularly derived from the difference between the first and second embodiments. It is not a thing.

  FIG. 9 is a flowchart illustrating basic functions of the illumination control unit 120 in the second embodiment illustrated in FIGS. 1 and 8. Since most of the contents are common to the flow in the first embodiment of FIG. 3, the corresponding steps are denoted by the same step numbers and description thereof is omitted. The flow in FIG. 9 is different from the flow in FIG. 3 in the steps shown in bold in FIG. 9 and is a notification portion when the life of the LED lighting device is exhausted. Specifically, in FIG. 9, when it is determined in step S6 that the life of the electrolytic capacitor has been exhausted, the process proceeds to step S144, and a process for notifying that the life has expired is executed. The fact that the “life has expired” is transmitted to the remote controller 10 and the flow is terminated. When a determination signal indicating that the LED has reached the end of its service life is detected in step S20, and when it is in the immediate extinguishing mode in step S24, the process proceeds to step S142, and if it is turned on, it can be lit again. The guidance display instruction signal is transmitted to the remote controller 10 and the process proceeds to step S144. Details of the notification processing in step S144 will be described later.

  FIG. 10 is a flowchart showing details of step S144 in the second embodiment shown in FIG. When the flow starts, in step S152, it is checked whether or not the setting for using the nightlight 104 for end-of-life notification is made. If the setting has been made, the process proceeds to step S154 to turn on the yellow LED of the nightlight. In step S156, it is checked whether the first setting has been made. If it is the first setting, the process proceeds to step S158, the divided white LED group 114 is normally lit, and the process proceeds to step S160. As described above, the first setting is to notify that the life of the divided white LED group 114 has expired by turning on the yellow LED 104 without changing the lighting state of the divided white LED group 114 itself. . Usually, since the yellow LED 104 and the divided white LED group 114 are not lit simultaneously, it is recognized that this is a notification of the end of life. On the other hand, if it is not the first setting in step S156, the process directly proceeds to step S160. Also, if the nightlight setting is not set in step S152, the process directly proceeds to step S160.

  Whether or not to perform the first setting as described above may be configured to be set in advance as a specification of the product when the LED lighting device is shipped, or set when the user installs the LED lighting device. You may comprise so that it can do. This is the same in the second to sixth settings described later. Note that the first to sixth settings cannot be set at the same time, and one of them is set to be selected. On the other hand, whether to set the nightlight notification setting can be arbitrarily set in combination with any of the second setting to the sixth setting. As is apparent from the flow from step S152 to step S158, the normal lighting of the white LED group based on the first setting is only possible in combination with the case where the nightlight notification is made.

  In step S160, it is checked whether the second setting has been made. If the setting is the second setting, the process proceeds to step S162. If the white LED group is disabled or turned on, the white LED group is turned off and the process proceeds to step S164. On the other hand, if it is not the second setting in step S160, the process directly proceeds to step S164. As described above, the second setting can be combined with or without the nightlight notification setting. However, when step S162 is reached without the nightlight notification setting, the second setting is the same as in the first embodiment. It becomes life exhaustion notification.

  In step S164, it is checked whether the third setting has been made. If it is the third setting, the process proceeds to step S166, the lighting duty cycle of the white LED group is decreased (for example, 1/4 of the normal) to dimm it, and the process proceeds to step S168. On the other hand, if it is not the third setting in step S164, the process directly proceeds to step S168. As described above, the third setting can be combined with or without the nightlight notification setting.

  In step S168, it is checked whether the fourth setting has been made. If it is the fourth setting, the process proceeds to step S170, where partial lighting control is performed to turn on part of the divided white LED group 114 and turn off other parts, and the process proceeds to step S172. In this case, the partial lighting is different from typical one-side lighting in the case of the normal lighting control, and is, for example, partial lighting that is peculiar to the end of life, such as lighting the divided portions alternately. On the other hand, if it is not the second setting in step S168, the process directly proceeds to step S172. As described above, the fourth setting can be combined with or without the nightlight notification setting.

  In step S172, it is checked whether the fifth setting has been made. If it is the fifth setting, the process proceeds to step S174, a process for instructing blinking lighting of the divided white LED group 114 is performed, and the process proceeds to step S176. On the other hand, if it is not the fifth setting in step S172, the process directly proceeds to step S176. As described above, the fifth setting can be combined with or without the nightlight notification setting.

  In step S176, it is checked whether the sixth setting has been made. If it is the sixth setting, the process proceeds to step S178, in which processing for instructing the brightness of the divided white LED group 114 to smoothly pulsate and change due to the duty change is performed, and the flow ends. On the other hand, if it is not the sixth setting in step S176, the flow is directly terminated. As described above, the fifth setting can be combined with or without the nightlight notification setting.

  As a modified example of the second embodiment, the yellow LED 104 in FIG. 8 may be replaced with a red LED, and may be configured as a dedicated display unit for displaying that the life has been exhausted instead of the night light. In this case, the night-light control unit 102 shall be read as the end of life notification control unit. In this case, “Evening light” in step S152 and step S154 in FIG. 10 is read as “red LED”. Further, step S152 may be omitted, and the red LED dedicated to the end of life notification may be turned on in any of the first to sixth settings.

  FIG. 11 is a block diagram illustrating Example 3 of the LED lighting system according to the embodiment of the present invention. In the third embodiment shown in FIG. 11, the same parts as those in the first embodiment shown in FIG. In Example 3 of FIG. 11, the LED lighting device and the fire alarm are integrated to form a fire alarm integrated LED lighting device 204, and the remote controller 10 is configured by infrared light 248 via a common wireless communication unit 224. Communicating with. Further, the illumination power supply unit 216 is supplied with power from the power line 12 in the same manner as the power supply unit 16 of FIG. 1, whereas the fire alarm power supply unit 230 is supplied with power from the button battery 203.

  In Example 3 of FIG. 11, the LED life determination unit and the electrolytic capacitor life determination unit are further omitted, and a battery detection unit 205 that detects the voltage of the button battery 203 is provided instead. And since the life of the button battery 203, the electrolytic capacitor of the lighting power source 216 and the white LED group 14 is approximately the same for about 10 years, the voltage of the button battery 203 is checked and it is detected that it has dropped below a predetermined level. Accordingly, it is determined that the entire life of the fire alarm integrated LED lighting device 204 has been exhausted. Then, by activating the battery detection unit 205 in conjunction with the lighting operation or dimming operation of the white LED group 14, the life detection of the fire alarm integrated LED lighting device 204 and the daily check of the fire alarm function are performed. It is configured to prevent the situation that does not work in case of emergency. The alarm-writer-made unit 232 cooperates for the above function under the control of the illumination control unit 220.

  FIG. 12 is a flowchart illustrating functions of the illumination control unit 220 illustrated in FIG. The flow starts when a lighting signal is received from the remote controller 10 as in the first embodiment. When the flow starts, the power supply voltage of the button battery 203 is checked by the battery detection unit 205 via the alarm control unit 232 in step S182. In step S184, it is determined whether or not the button battery has expired. If the lifetime has expired, a signal indicating that the power battery of the fire alarm has been exhausted is transmitted to the remote controller 10 in step S186.

  Next, in step S188, it is checked whether the lighting signal that started the flow of FIG. 12 is a lighting signal by an operation within a predetermined time (for example, 30 seconds) after the LED is turned off when the button battery has reached the end of its life. This is for re-lighting by performing a lighting operation within a predetermined time when an LED that is lit in an immediate light-off mode to be described later suddenly turns off due to the end of the button battery life.

  If the operation does not correspond to step S188, the process proceeds to step S190 to check whether the lighting signal that started the flow of FIG. 12 is received within a predetermined time (for example, 1 second) after the previous operation. This means that it is determined that the life of the button battery has been exhausted, and even if the LED lighting device does not light up in a normal lighting operation, a special operation of performing a continuous operation within an interval of 1 second is performed. It is for enabling lighting. If the operation corresponds to step S190, the process proceeds to step S192, and after determining that the button battery has reached the end of its life, it is checked whether the operation is within a predetermined number of times (for example, five times). This is because of the convenience of use, but even if the button battery has reached the end of its lifetime, it can be lit by a special operation called continuous operation. This is to prevent the lighting operation from continuing for a long time despite being considered exhausted.

  When the operation is within the predetermined number of times in step S192, the process proceeds to step S194, the operation signal reception count is incremented by one, and the process proceeds to step S196 to turn on the LED. On the other hand, if it is not determined in step S184 that the button battery has reached the end of its life, the process proceeds directly to step S196, where the LED is immediately turned on. If it is confirmed in step S188 that the LED is a lighting signal within a predetermined time after the LED is turned off due to the life of the button battery, the process directly proceeds to step S196 to turn on the LED.

  When the LED is turned on in step S196, the process proceeds to step S198, where it is checked whether a manual dimming signal is received from the remote controller 10. If there is reception, the process proceeds to step S200, and the power supply voltage of the button battery 203 is checked. In step S202, it is determined whether or not the button battery has expired. If the lifetime has expired, a signal indicating that the power battery of the fire alarm has been exhausted is transmitted to the remote controller 10 in step S204. In this way, the button battery is checked not only during the lighting operation but also during the dimming operation. Furthermore, in step S206, when a determination signal indicating that the button battery has reached the end of its life is generated, it is checked whether or not the mode is set to immediately turn off the LED. If it is not the immediate light-off mode, the light is not turned off and the process proceeds to step S208. On the other hand, if there is no signal indicating that the button battery has reached the end of its life in step S202, the process directly proceeds to step S208.

  In step S208, a new due cycle signal based on the manual dimming signal detected in step S198 is output, and the process proceeds to step S210. On the other hand, when the manual light control signal is not detected in step S198, the process directly proceeds to step S210. In step S210, it is checked whether a turn-off signal has been received from the remote controller 10. If no turn-off signal is received, the process returns to step S198. Steps S198 to S210 are repeated unless the turn-off signal is received and a signal indicating that the button battery has reached the end of its life in the immediate turn-off mode. Or it corresponds to the change of the life state of the button battery. On the other hand, when the reception of the turn-off signal is confirmed in step S210, the flow ends.

  When the button battery has reached the end of its life, if it is not detected in step S190 that the lighting signal is within a predetermined time after the previous operation, the process proceeds to step S212. Is transmitted to the remote controller 10 and the process proceeds to step S214. On the other hand, when it is detected in step S192 that the lighting is performed by a predetermined operation or more, the process immediately proceeds to step S214. In any case, the lighting is not executed in accordance with the lighting operation. In step S214, “non-lighting” is transmitted to the remote controller 10 and the flow is ended. If it is in the immediate turn-off mode in step S206, the process moves to step S216 to execute the immediate turn-off of the LED, and in step S218, a guidance display indicating that the light can be turned on again if operated within a predetermined time. An instruction signal is transmitted to the remote controller 10, and the flow ends.

  As a modified example of the third embodiment, the button battery 203 of the alarm power supply unit 230 is not diverted when determining the life of the fire alarm integrated LED lighting device 204 as a whole. Further, it is possible to determine the lifetime of the entire fire alarm integrated LED lighting device 204 by checking the voltage of the button battery dedicated to life determination together with the voltage check of the button battery 203. In addition, when a button battery dedicated for life determination is added in this way, a button dedicated for life determination corresponding to deterioration of the white LED group 14 is caused by flowing a current corresponding to the lighting current of the white LED group 14 to the button battery for life determination. You may comprise so that consumption of a battery may arise.

  Further, in FIG. 11, the LED lighting device 6 may be configured such that the LED life determination unit and the electrolytic capacitor life determination unit are omitted, and the life of the LED lighting device 6 is determined based on the consumption of the button battery for life determination. In this case, even if a plurality of LED lighting devices in the same room are turned on for the same time under the same conditions, due to variations in the life of the button battery, the plurality of LED lighting devices are simultaneously used for the end of the LED life. The next LED lighting device is turned off with sufficient time to replace the LED lighting device that has been turned off earliest.

The present invention can be applied to, for example, an illumination device having an LED illumination device or an electrolytic capacitor.
