Description

  The present invention relates to a lighting device that notifies a user of a replacement time.

When an electronic component or a light source used in a lighting circuit of a lighting device (lighting fixture) reaches the end of its life, the illuminance of the light source may decrease or the light source may not light. In order to avoid this, it is necessary to inform the user of the replacement time of the instrument and the light source and to prompt the replacement.
Therefore, for example, there is an apparatus that provides an indicator lamp for notifying the user of the replacement time of the appliance or light source, and turns on the indicator lamp when it is determined that it is time to replace the appliance or light source.
In particular, in recent years, lighting devices using LED elements as light sources have begun to spread. The lifetime of the illuminating device using the LED element is much longer than the lifetime of the illuminating device using the fluorescent lamp, for example, exceeding 40,000 hours (10 years or more when used for 10 hours a day).

JP 2008-251441 A

Due to the long life of the lighting device, when the replacement time of the lighting device is reached, the user may not remember the time when the lighting device was purchased. Also, the indicator lamp and the circuit for lighting the indicator lamp have a lifetime and may break down. If the indicator lamp or the circuit for lighting the indicator lamp breaks down before the fixture or the light source is replaced, it may not be possible to notify the user of the replacement timing correctly. Furthermore, if the user is notified after reaching the replacement time, there is a problem that the user cannot grasp the state of the lighting device before the replacement time is reached.
The present invention has been made, for example, in order to solve the above-described problems, and an object of the present invention is to surely notify the user of the replacement time of the instrument and the light source.

  In the lighting device according to the present invention, whether or not at least one of a lighting circuit that converts electric power supplied from an external power source into electric power for lighting a main light source, and the lighting circuit and the main light source is a replacement time. A replacement time determination unit that determines whether the replacement time is reached, and when the replacement time determination unit determines that it is a replacement time, lights up in a first display color indicating that it is a replacement time, and if it is not a replacement time, the replacement time determination unit When it is determined, the battery has a replacement time indicator lamp that lights in a second display color indicating that it is not a replacement time.

  Since the replacement time indicator lamp is lit not only when the replacement time is reached but also before the replacement time, the difference in the display color of the replacement time indicator and the replacement time indicator light By not lighting, it is possible to reliably notify the user that the lighting device should be replaced / repaired.

Embodiment 1 FIG.
The first embodiment will be described with reference to FIGS.

FIG. 1 is a block configuration diagram showing the configuration of the illumination device 100 in this embodiment.
The lighting device 100 turns on the main light source LA with power supplied from the external power source AC. The external power source AC is an AC power source such as a commercial power source. For example, a power switch SW (input power switch) is interposed between the external power source AC and the lighting device 100. The user turns on or off the main light source LA of the lighting device 100 by turning on and off the power switch SW.
The main light source LA is a light source that emits light by the power supplied from the lighting device 100. The main light source LA may be a light source that emits light by direct current power, such as an LED or an organic EL, and may be a light source that emits light by alternating current power, such as a discharge lamp. The main light source LA is detachably attached to the lighting device 100. The main light source LA may be fixed to the lighting device 100 as a part of the lighting device 100.
The illumination device 100 includes, for example, a main light source lighting circuit 110, a replacement time determination unit 130, a display determination unit 140, a display lamp lighting circuit 150, and a replacement time display lamp 160.
The main light source lighting circuit 110 (lighting circuit) converts the power supplied from the external power source AC into power supplied to the main light source LA. The main light source lighting circuit 110 is, for example, a power conversion circuit.
The replacement time determination unit 130 determines the replacement time of the main light source lighting circuit 110 and the main light source LA. The replacement time refers to a state in which the main light source lighting circuit 110 and the main light source LA are not strange at the end of their lifetime. The replacement time determination unit 130 determines the replacement time in two stages, for example, whether or not it is a replacement time, or in three stages that there is still a margin until the replacement time, the replacement time is near, or the replacement time. The replacement time determination unit 130 measures, for example, a time during which power is supplied from the external power source AC to the main light source lighting circuit 110, a time during which the main light source LA is lit, and the replacement time based on the measured time. Determine. The replacement time determination unit 130 outputs, for example, a signal indicating the determination result.
The replacement time indicator lamp 160 (LED display unit) displays the determination result determined by the replacement time determination unit 130. The replacement time indicator lamp 160 is a light source provided separately from the main light source LA, such as a display LED. The replacement time indicator lamp 160 represents a determination result by, for example, a color difference. For example, the replacement time indicator lamp 160 is red (first display color) when it is a replacement time, yellow (second display color) when the replacement time is near, and green (third) when there is a margin until the replacement time. Display color). The replacement time indicator lamp 160 is lit by the electric power supplied from the indicator lamp lighting circuit 150. Alternatively, the replacement time indicator lamp 160 may have a configuration in which the display color is changed not in the case of three stages but in the case of two stages. For example, red (first display color) indicates a replacement time, and green (second display color) indicates a non-replacement time (including a case where the replacement time is near and a time until the replacement time is sufficient). Below, although the structure which divides into three cases is mainly demonstrated, it does not intend to limit to this.
The display determination unit 140 determines whether or not to display the determination result determined by the replacement time determination unit 130 on the replacement time indicator lamp 160. For example, the display determination unit 140 (replacement time display operation input unit) determines whether or not to display the determination result of the replacement time determination unit 130 on the replacement time indicator lamp 160 according to the user's operation. For example, the display determination unit 140 includes a replacement time display switch operated by the user, and causes the replacement time display lamp 160 to display the determination result of the replacement time determination unit 130 while the user is pressing the replacement time display switch. Is determined. Alternatively, the display determination unit 140 receives the signal from the remote controller operated by the user, and exchanges the determination result of the replacement time determination unit 130 when the user presses the replacement time display switch provided on the remote control. It is determined to be displayed on the time indicator lamp 160. Or the display determination part 140 acquires operation of the power switch SW by a user by determining whether electric power is supplied to the illuminating device 100 from the external power supply AC, and replaces | exchanges based on the acquired operation. It is determined whether or not the determination result of the time determination unit 130 is displayed on the replacement time indicator lamp 160. For example, when the operation pattern of the power switch SW by the user is a predetermined operation pattern (for example, a special operation pattern that is different from a normal lighting operation or an extinguishing operation such as ON / OFF being repeated a predetermined number of times within a predetermined time). 140 determines that the determination result of the replacement time determination unit 130 is displayed on the replacement time indicator lamp 160. Alternatively, the display determination unit 140 displays the determination result of the replacement time determination unit 130 on the replacement time indicator lamp 160 immediately after the power supply from the external power source AC starts or immediately after the power supply from the external power source AC stops. Determine that you want to.
The display determination unit 140 determines that the determination result of the replacement time determination unit 130 is to be displayed on the replacement time indicator lamp 160, and then until the predetermined time (for example, 3 seconds) elapses. It may be determined that the determination result is continuously displayed on the replacement time indicator lamp 160, and then the determination result of the replacement time determination unit 130 is determined not to be displayed on the replacement time indicator lamp 160.
The display determination unit 140 outputs a signal for controlling the indicator lamp lighting circuit 150 based on the determination result. When it is determined that the determination result of the replacement time determination unit 130 is to be displayed, the display determination unit 140 outputs a signal representing the determination result of the replacement time determination unit 130. When it is determined that the determination result of the replacement time determination unit 130 is not displayed, the display determination unit 140 outputs a signal for stopping the operation of the indicator lamp lighting circuit 150.
The indicator lamp lighting circuit 150 supplies power to the replacement time indicator lamp 160. The indicator lamp lighting circuit 150 converts, for example, power supplied from the external power supply AC into power supplied to the replacement time indicator lamp 160. The indicator lamp lighting circuit 150 turns on or off the replacement time indicator lamp 160 according to a signal from the display determination unit 140.

FIG. 2 is a perspective view showing an appearance of the illumination device 100 according to this embodiment.
The illuminating device 100 includes, for example, an appliance body 1, a socket 3, a first display unit 4, a second display unit 5, and a third display unit 6. The instrument body 1 includes a main light source lighting circuit 110 and the like. The socket 3 fixes the main light source LA in a detachable manner, and electrically connects the main light source LA to the main light source lighting circuit 110. The three display units 4 to 6 are an example of the replacement time indicator lamp 160. The display unit 4 includes an LED that emits green light. The display unit 5 includes an LED that emits yellow light. The display unit 6 includes an LED that emits red light. By dividing the display unit according to the light emission color in this way, the replacement time indicator lamp 160 represents the determination result of the replacement time not only by the light emission color but also by the light emission position.

FIG. 3 is a circuit diagram showing a circuit configuration of illumination apparatus 100 in this embodiment.
The lighting device 100 includes a main light source lighting circuit 110, a power supply circuit 120, an indicator lamp lighting circuit 150, a replacement time indicator lamp 160, an input power source detection circuit 170, and a lighting control circuit 180.
The power supply circuit 120 converts the power supplied from the external power supply AC into DC power. The power supply circuit 120 includes, for example, an input filter circuit 121, a full-wave rectifier circuit 122, a boost chopper circuit 123, and a smoothing capacitor 124. The input filter circuit 121 prevents noise from entering the power supply circuit 120 from the outside of the lighting device 100 and prevents noise generated in the boost chopper circuit 123 from leaking to the outside of the lighting device 100. The full-wave rectifier circuit 122 performs full-wave rectification on the AC power supplied from the external power supply AC. The step-up chopper circuit 123 boosts the pulsating current rectified by the full-wave rectifier circuit 122 to make it a direct current. The smoothing capacitor 124 smoothes the direct current generated by the boost chopper circuit 123. The smoothing capacitor 124 is a capacitor having a relatively large capacity, and the lighting control circuit 180 and the indicator lamp lighting circuit 150 can be operated for a predetermined time (for example, several seconds) after the supply of power from the external power source AC is stopped. it can.
The input power supply detection circuit 170 detects whether or not power is supplied to the lighting device 100 from the external power supply AC.
The lighting control circuit 180 controls the lighting state of the main light source LA and the replacement time indicator lamp 160 by controlling the main light source lighting circuit 110 and the indicator lamp lighting circuit 150. The lighting control circuit 180 is a microcomputer, for example. The lighting control circuit 180 includes a nonvolatile memory and a volatile memory that store programs and data. The lighting control circuit 180 functions as the replacement time determination unit 130 and the display determination unit 140 described above by executing a program stored in advance using a nonvolatile memory. The lighting control circuit 180 operates with DC power converted by the power supply circuit 120.
The main light source lighting circuit 110 converts the DC power converted by the power supply circuit 120 into power supplied to the main light source LA. The main light source lighting circuit 110 operates according to the control by the lighting control circuit 180. For example, the main light source lighting circuit 110 turns on or off the main light source LA or changes the brightness at which the main light source LA is turned on according to the control by the lighting control circuit 180.
The indicator lamp lighting circuit 150 operates according to control by the lighting control circuit 180. For example, the indicator lamp lighting circuit 150 lights or extinguishes the display units 4 to 6 of the replacement time indicator lamp 160 according to the control by the lighting control circuit 180. The indicator lamp lighting circuit 150 operates with DC power converted by the power supply circuit 120.

  FIG. 4 is a flowchart showing an operation flow of the illumination device 100 according to this embodiment.

When the power switch SW is turned on and the power is turned on, the lighting device 100 first executes a lighting process S510.
In the lighting process S510, the main light source lighting circuit 110 converts the power supplied from the external power source AC into the power supplied to the main light source LA. As a result, the main light source LA is turned on.
In the replacement time determination process S520, the lighting control circuit 180 (replacement time determination unit 130) determines the replacement time of the main light source lighting circuit 110 and the main light source LA.
In the display determination process S530, the lighting control circuit 180 (display determination unit 140) determines whether or not to display the replacement time. When it determines with displaying, the illuminating device 100 advances a process to replacement | exchange time display process S560. When it determines with not displaying, the illuminating device 100 advances a process to the light extinction determination process S580.
In the replacement time display process S560, the indicator lamp lighting circuit 150 lights the replacement time display lamp 160 according to the determination result in the replacement time determination process S520.
In the turn-off determination process S580, the turn-on control circuit 180 determines whether or not the main light source LA is turned off. For example, based on the detection result of the input power supply detection circuit 170, the lighting control circuit 180 determines that the main light source LA is turned off when the power supply from the external power supply AC is not longer than a predetermined time (for example, 1 second). If it is determined that the light is extinguished, the lighting device 100 proceeds to the extinguishing process S590. When it determines with not turning off, the illuminating device 100 returns a process to replacement | exchange time determination process S520.
In the turn-off process S590, the main light source lighting circuit 110 stops operating. As a result, the main light source LA is turned off.

FIG. 5 is a flowchart showing the flow of the replacement time determination process S520 in this embodiment.
In this example, the lighting control circuit 180 (replacement time determination unit 130) determines the replacement time of the main light source lighting circuit 110 by accumulating the time during which power is supplied from the external power supply AC (energization time).
The replacement time determination process S520 includes, for example, an energization determination step S521, an energization time accumulation step S522, and a replacement time determination step S529.
In the energization determination step S521, the lighting control circuit 180 determines whether there is power supply from the external power source AC based on the detection result of the input power source detection circuit 170. When there is power supply from the external power supply AC (in an energized state), the lighting device 100 proceeds to the energization time accumulation step S522. When there is no power supply from the external power supply AC (not in the energized state), the lighting device 100 proceeds to the replacement time determination step S529.
In the energization time accumulation step S522, the lighting control circuit 180 accumulates the energization time. The lighting control circuit 180 stores the energization time using a nonvolatile memory. The lighting control circuit 180 accumulates the energization time based on the stored energization time. The lighting control circuit 180 stores the accumulated energization time again using a nonvolatile memory or the like.
In the replacement time determination step S529, the lighting control circuit 180 determines the replacement time of the main light source lighting circuit 110 based on the stored energization time. For example, the lighting control circuit 180 compares the energization time with a predetermined first threshold (for example, 40,000 hours). When the energization time is greater than the first threshold, the lighting control circuit 180 determines that the main light source lighting circuit 110 is in the replacement period (replacement period). When the energization time is smaller than the first threshold, the lighting control circuit 180 compares the energization time with a predetermined second threshold (for example, 30,000 hours) smaller than the first threshold. When the energization time is greater than the second threshold value, the lighting control circuit 180 determines that the replacement time of the main light source lighting circuit 110 is near (life notice period). When the energization time is smaller than the second threshold value, the lighting control circuit 180 determines that there is still a margin until the replacement time of the main light source lighting circuit 110 (lifetime).

FIG. 6 is a flowchart showing the flow of the display determination process S530 in this embodiment.
In this example, the lighting control circuit 180 (display determination unit 140) determines to display the determination result of the replacement time when the power switch SW is operated with a predetermined operation pattern.
The display determination process S530 includes, for example, a display request operation determination step S532.
In the display request operation determination step S532, the lighting control circuit 180 determines whether or not the power switch SW is operated in a predetermined operation pattern based on the detection result of the input power supply detection circuit 170. When it is determined that the operation has been performed with the predetermined operation pattern, the lighting device 100 proceeds to the replacement time display process S560. When it is determined that there is no operation with the predetermined operation pattern, the lighting device 100 proceeds to the extinction determination process S580.

FIG. 7 is a flowchart showing the flow of the replacement time display process S560 in this embodiment.
The replacement time display process S560 includes, for example, a replacement time branching process S561, a first display lighting process S562, a second display lighting process S563, a third display lighting process S564, a time lapse waiting process S565, and a display extinguishing process. S566.
In the replacement time branching step S561, the lighting control circuit 180 branches the processing based on the determination result in the replacement time determination processing S520. In the case of the determination result that there is a margin until the replacement time, the lighting device 100 proceeds to the first display lighting step S562. In the case of the determination result that the replacement time is near, the lighting device 100 proceeds to the second display lighting step S563. In the case of the determination result that it is the replacement time, the lighting device 100 proceeds to the third display lighting step S564.
In the first display lighting step S562, the indicator lamp lighting circuit 150 lights the display unit 4 (green) and does not light the display unit 5 (yellow) and the display unit 6 (red). The illuminating device 100 advances a process to time passage waiting process S565.
In the second display lighting step S563, the indicator lamp lighting circuit 150 lights the display unit 5 (yellow) and does not light the display unit 4 (green) and the display unit 6 (red). The illuminating device 100 advances a process to time passage waiting process S565.
In the third display lighting step S564, the indicator lamp lighting circuit 150 lights the display unit 6 (red) and does not light the display unit 4 (green) and the display unit 5 (yellow). The illuminating device 100 advances a process to time passage waiting process S565.
In the time lapse waiting step S565, the indicator lamp lighting circuit 150 waits for a predetermined time (for example, 3 seconds) to elapse. When the predetermined time has elapsed, the lighting device 100 proceeds to the display extinguishing step S566.
In the display turn-off step S566, the indicator lamp lighting circuit 150 turns off all the display units 4-6.

  Thus, according to the determination result of the replacement time determination unit 130, the replacement time indicator lamp 160 lights any one of the display units 4 to 6. The replacement time indicator lamp 160 is lit not only when the replacement time is near or when the replacement time is near, but also when there is a margin until the replacement time.

In general, in the lighting device 100, the main light source lighting circuit 110 and the main light source LA are assumed to have the shortest lifetime. However, before the main light source lighting circuit 110 and the main light source LA reach the replacement time, other parts of the illumination device 100 such as the replacement time indicator lamp 160 may break down.
For example, when the display unit 6 fails and does not turn on, even if the main light source lighting circuit 110 and the main light source LA are replaced, the display unit 6 is not turned on, so that it is not possible to indicate that it is the replacement time. However, since any one of the display units 4 to 6 should be lit, but none of the display units 4 to 6 is lit, the user can be informed that there is a problem somewhere in the lighting device 100. For this reason, the user can recognize that the lighting device 100 should be repaired or replaced.

  The replacement time indicator lamp 160 has a single display unit instead of the independent display units 4 to 6 and displays the determination result of the replacement time only by the color change when the display unit lights up. May be. For example, the replacement time indicator lamp 160 may have a configuration having three or two LEDs having different emission colors and a diffuse transmission cover that covers the whole. In that case, since two LEDs (for example, red and green) having different emission colors emit light at the same time, the light emitted by the two LEDs can be mixed to create a third emission color (for example, orange). Two LEDs can distinguish and display three states.

  Moreover, the illuminating device 100 may be the structure which changes the waiting time in time passage waiting process S565 according to the determination result in replacement | exchange time determination process S520. For example, when there is a margin until the replacement time, the waiting time is shortened, and conversely, when it is the replacement time, the waiting time is lengthened. By doing so, the determination result of the replacement time can be expressed not only by the light emission color and light emission position of the replacement time indicator lamp 160 but also by the time when the replacement time indicator lamp 160 is lit. Can be surely notified to the user.

Note that the case where the replacement time determination unit 130 makes a determination based on the two cases of whether or not it is the replacement time and the replacement time indicator lamp 160 is configured to change the display color is apparent from the above description. The description is omitted.
In addition, for example, it is further discriminated how much time is left until the replacement time, and the replacement time determination unit 130 determines according to the case of four or more stages, and the replacement time indicator lamp 160 changes the display color. It is good also as composition to do.

  FIG. 8 is a flowchart showing an operation flow of the lighting apparatus 100 according to this embodiment.

When it determines with displaying by display determination process S530, the illuminating device 100 advances a process to the light reduction process S540.
In the dimming process S540, the main light source lighting circuit 110 reduces the power supplied to the main light source LA. As a result, the main light source LA is lit darker than normal.
In the all display process S550, the indicator lamp lighting circuit 150 lights all the display units 4-6.
In the replacement time display process S560, the indicator lamp lighting circuit 150 lights the replacement time display lamp 160 according to the determination result in the replacement time determination process S520. When the turn-off operation is performed while the replacement time indicator lamp 160 displays the replacement time, the lighting device 100 advances the process to the turn-off process S690. In other cases, the lighting device 100 proceeds to the return process S570.
In the return process S570, the main light source lighting circuit 110 restores the power supplied to the main light source LA reduced in the dimming process S540. As a result, the main light source LA returns to the same brightness as during normal operation. The lighting device 100 returns the process to the replacement time determination process S520.
In the turn-off process S690, the main light source lighting circuit 110 stops operating. As a result, the main light source LA is turned off.

After the extinguishing process S590, the lighting device 100 proceeds to the all display process S650.
In all display processing S650, the indicator lamp lighting circuit 150 lights all the display units 4-6.
In the replacement time display process S660, the indicator lamp lighting circuit 150 lights the replacement time display lamp 160 according to the determination result in the replacement time determination process S520.

FIG. 9 is a flowchart showing the flow of the replacement time determination process S520 in this embodiment.
In this example, the lighting control circuit 180 (replacement time determination unit 130) determines the replacement time of the main light source LA by accumulating the time during which the main light source LA is lit (lighting time).
The replacement time determination process S520 includes a replacement determination step S524, a lighting time initialization step S525, a lighting determination step S526, a lighting time accumulation step S527, and a replacement time determination step S529.
In the replacement determination step S524, the lighting control circuit 180 determines whether or not the main light source LA has been replaced. When it determines with having replaced | exchanged, the illuminating device 100 advances a process to lighting time initialization process S525. When it determines with not having exchanged, the illuminating device 100 advances a process to lighting determination process S526.
In the lighting time initialization step S525, the lighting control circuit 180 initializes the lighting time. The lighting control circuit 180 stores the lighting time using a nonvolatile memory. The lighting control circuit 180 initializes the stored lighting time to zero. The lighting control circuit 180 stores the initialized lighting time using a nonvolatile memory.
In the lighting determination step S526, the lighting control circuit 180 determines whether or not the main light source LA is lit. When it determines with having lighted, the illuminating device 100 advances a process to lighting time accumulation process S527. When it determines with it not lighting, the illuminating device 100 advances a process to replacement | exchange time determination process S529.
In the lighting time accumulation step S527, the lighting control circuit 180 accumulates the lighting time. The lighting control circuit 180 accumulates the lighting time based on the stored lighting time. The lighting control circuit 180 stores the accumulated lighting time again using a nonvolatile memory or the like.
In the replacement time determination step S529, the lighting control circuit 180 determines the replacement time of the main light source LA based on the stored lighting time. For example, the lighting control circuit 180 compares the lighting time with a predetermined first threshold (for example, 40,000 hours). When the lighting time is larger than the first threshold value, the lighting control circuit 180 determines that the main light source LA is the replacement time. When the lighting time is smaller than the first threshold, the lighting control circuit 180 compares the lighting time with a predetermined second threshold (for example, 30,000 hours) smaller than the first threshold. When the lighting time is larger than the second threshold, the lighting control circuit 180 determines that the replacement time of the main light source LA is near. When the lighting time is smaller than the second threshold, the lighting control circuit 180 determines that there is still a margin until the replacement time of the main light source LA.

FIG. 10 is a flowchart showing the flow of display determination processing S530 in this embodiment.
In this example, when the lighting control circuit 180 (display determination unit 140) determines that it is the replacement time in the replacement time determination processing S520, it determines that the determination result is forcibly displayed.
The display determination process S530 includes, for example, a replacement time branching step S531 and a display request operation determination step S532.
In the replacement time branching step S531, the lighting control circuit 180 determines whether it is the replacement time based on the determination result in the replacement time determination processing S520. When it is determined that it is the replacement time, the lighting control circuit 180 proceeds to the dimming process S540. If it is determined that the replacement time is not reached (there is a margin until the replacement time or the replacement time is near), the lighting device 100 proceeds to the display request operation determination step S532.

FIG. 11 is a flowchart showing the flow of the all display process S550 in this embodiment.
The all display process S550 includes, for example, an all display lighting process S551, a time elapse waiting process S552, and a display extinguishing process S553.
In the all display lighting step S551, the indicator lamp lighting circuit 150 lights all the display units 4-6.

  Thus, when the replacement time indicator lamp 160 displays the determination result of the replacement time, the main light source LA is darkened, so that the display of the replacement time indicator lamp 160 is easy to see. Since a relatively low illuminance LED can be used for the replacement time indicator lamp 160, the manufacturing cost of the lighting device 100 can be reduced. Further, when the main light source LA becomes dark, the user can be informed that the lighting device 100 has accepted the replacement time display operation. The illumination device 100 may be configured to temporarily turn off the main light source LA instead of darkening the main light source LA when displaying the determination result of the replacement time.

Moreover, since all the display units 4 to 6 are turned on before displaying the determination result of the replacement time, it is possible to notify the user that the lighting device 100 has accepted the replacement time display operation.
Furthermore, when any one of the display units 4 to 6 fails and does not light up, it can be determined which display unit 4 to 6 is malfunctioning. For example, when all the display units 4 to 6 should be lit but only the display unit 4 is not lit, it is understood that the display unit 4 has failed. Therefore, when displaying the determination result of the replacement time, the determination result can be notified to the user even when none of the display units 4 to 6 is lit. For example, when it is known that the display unit 4 is out of order, any of the display units 4 to 6 should be lit, but if any of the display units 4 to 6 are not lit, the display should be lit up originally. It is part 4 and it can be seen that there is a margin until the replacement time. If it is known that the display unit 6 is out of order, it is known that it is time to replace.

In addition, the illuminating device 100 may have a configuration in which the display units 4 to 6 are not lit at the same time in the all display process S550 but are lit in order one by one.
The lighting device 100 does not turn on the display units 4 to 6 according to the determination result in the replacement time display process S560 after the display units 4 to 6 are turned on and turned off in the full display process S550. After the display units 4 to 6 are turned on in the process S550, the other display units 4 to 6 may be turned off while leaving only the display units 4 to 6 according to the determination result in the replacement time display process S560. .

Even if there is no operation by the user, when the main light source LA is turned off, the determination result of the replacement time is automatically displayed, so that the user can be notified of the determination result of the replacement time. Accordingly, even when the user neglects to confirm the replacement time, the user can be surely notified that the replacement time is near.
Further, since the learning effect that the user learns that the replacement time indicator lamp 160 is always turned on when the lamp is turned off is expected, when the replacement time indicator lamp 160 stops lighting, the user recognizes that it has failed and repairs or replaces it. It can be expected that necessary measures will be taken.

In addition, in the case of the determination result that it is the replacement time, the determination result is automatically displayed even if there is no operation by the user or the main light source LA is not turned off. I can inform you.
Furthermore, when the determination result indicating that it is the replacement time is displayed, the display does not return even after a predetermined time has elapsed, and the display is continued until the user turns off the main light source LA. The user can be informed and necessary measures such as repair or replacement can be taken.
Note that the illumination device 100 may have a configuration in which the main light source LA is not darkened in the case of forced display due to the replacement time. Or the illuminating device 100 may be the structure which returns only the brightness of the main light source LA to the original brightness, continuing the display that it is a replacement time, after predetermined time passes. If it does so, it can continue using the illuminating device 100, without illuminance being insufficient until main light source LA etc. are replaced | exchanged.
