  On the other hand, in the external power supply state, the power supply detection circuit 12 detects the supply state of the external power supply and instructs the charge control circuit 13 to charge the battery 13a with the power supplied from the external power supply (first step) ). The charge control circuit 13 controls the lighting state of the charge monitor 88 according to the charge control state of the charge control circuit 13 described later (second step). The first step and the second step do not matter in the order of control.
  In the external power supply state, the charging control circuit 13 only controls charging of the battery 13a, and does not supply power from the external power source and the battery 13a to the auxiliary light source lighting control means 86b and the first receiver control circuit 81b. Therefore, in the external power supply state, the first receiving unit 81 cannot receive the signal transmitted from the remote control transmitter R, and the safety lamp 86 cannot be turned on.
  Next, a state where the external power supply stops supplying power, or a state where the external power supply supplies power but a power switch SW such as a wall switch is open (hereinafter referred to as a power supply stop state). The operation of the lighting device 100 at) will be described.
  Since the power supply to the second receiver control circuit 84b is stopped in the power supply stop state, the second receiver 84 cannot receive the signal transmitted from the remote control transmitter R. Therefore, in the power supply stop state, the light source unit 6 and the nightlight 85 cannot be controlled to be turned on. If the light source unit 6 has been turned on or dimmed before the power supply is stopped, or if the nightlight 85 has been turned on or dimmed, the light source unit 6 and the nightlight 85 are turned off.
  On the other hand, when detecting the power supply stop state, the power supply detection circuit 12 instructs the charge control circuit 13 to supply the power stored in the battery 13a to the auxiliary light source lighting control circuit 86b and the first receiver control circuit 81b. (Third step). The charge control circuit 13 controls the lighting of the charge monitor 88 with the end of the charge control, that is, the start of the discharge control (fourth step). In the power supply stop state, the charge monitor 88 is preferably turned off by the charge control circuit 13 in order to reduce the power consumption of the battery 13a. On the other hand, when the first receiver control circuit 81b is supplied with power from the battery 13a, the first receiver 81 can receive a signal transmitted from the remote control transmitter R (fifth step). The auxiliary light source lighting control circuit 86b turns on the safety lamp 86 when power is supplied from the battery 13a (sixth step). The third step to the sixth step are not limited to the order of control.
  In the power supply stop state, the first receiver 81 is in a state where it can receive a signal sent from the remote control transmitter R, and therefore, for example, a light source extinguishing signal or a nightlight extinguishing signal is sent from the remote control transmitter R. When the reception unit 81 receives the light source extinction signal or the nightlight extinction signal, the first reception unit 81 sends a signal based on the light source extinction signal or the nightlight extinction signal to the first reception unit control circuit 81b. When the first receiver control circuit 81b receives a signal based on the light source extinction signal or the nightlight extinction signal, the auxiliary light source lighting control circuit 86b instructs the auxiliary light source lighting control circuit 86b to perform control to turn off the security lamp 86. .
  In the power supply stop state, for example, when the all-light lighting signal or the nightlight lighting signal is transmitted from the remote control transmitter R and the first receiver 81 receives the all-light lighting signal or the nightlight lighting signal, the auxiliary light source is operated by the same operation. The lighting control circuit 86b lights the security lamp 86.
  In the power supply stop state, for example, a dimming control signal or a nightlight dimming signal is transmitted from the remote control transmitter R, and when the first receiving unit 81 receives the dimming control signal or the nightlight dimming signal, The auxiliary light source dimming circuit 86c performs dimming control of the safety lamp 86.
  In the power supply stop state, the charge control circuit 13 supplies the power stored in the battery 13a to the auxiliary light source lighting control circuit 86b and the first receiver control circuit 81b, and the battery voltage detection circuit provided in the charge control circuit 13 13b starts the detection of the battery voltage at the time of supplying the electric power stored in the battery 13a to the auxiliary light source lighting control circuit 86b and the first receiver control circuit 81b.
  A control signal based on the battery voltage as a detection value by the battery voltage detection circuit 13b is sent to the auxiliary light source lighting control circuit 86b. The auxiliary light source lighting control circuit 86b has a first battery voltage, a second battery voltage, a third battery voltage, and a fourth battery voltage as threshold values of the battery voltage.
  As shown in FIG. 6A, the auxiliary light source lighting control circuit 86b compares the battery voltage sent from the battery voltage detection circuit 13b with the battery voltage threshold, and when the battery voltage is higher than the first battery voltage, The auxiliary light source dimming circuit 86c is instructed to turn on the safety light 86 so that the light output of the safety light 86 becomes the light output A. The auxiliary light source dimming circuit 86c performs dimming control of the safety light 86 so that the light output of the safety light 86 becomes the light output A. The auxiliary light source dimming circuit 86c controls the safety lamp 86 by PWM (pulse width modulation) control.
  When the battery voltage falls below the first battery voltage, the auxiliary light source dimming circuit 86c performs dimming control of the safety lamp 86 with the light output B smaller than the light output A. Thereafter, similarly, as shown in FIG. 6A, as the battery voltage decreases, the auxiliary light source dimming circuit 86c sequentially decreases the light output to the light output B, the light output C, and the light output D. .
  When dimming control of the safety lamp 86 according to the battery voltage, even if a dimming control signal is transmitted from the remote control transmitter R, the dimming control based on the battery voltage is given priority. Further, it may be possible to control only lighting and extinguishing from the remote control transmitter R.
  6A, the light output of the safety light 86 is decreased stepwise in a stepwise manner as the battery voltage decreases. However, it may be decreased in a slope shape at a constant reduction rate.
  An operation of the lighting device 100 in a state where the power supply is stopped from the external power supply state (hereinafter referred to as a power supply return state) will be described.
  Since the power supply to the second receiver control circuit 84b is resumed in the power supply return state, the second receiver returns to the state in which the signal transmitted from the remote control transmitter R can be received (seventh step). . The operations after the seventh step are the same as in the external power supply state.
In the power supply return state, the power supply detection circuit 12 detects resumption of power supply from the external power supply (eighth step). When the power supply detection circuit 12 detects the resumption of power supply from the external power supply, the charging control circuit 13 stops the power supply from the battery 13a to the auxiliary light source lighting control circuit 86b, and the safety light 86 is turned off (9th step). ). When the power supply detection circuit 12 detects the resumption of power supply from the external power supply, the charging control circuit 13 stops the power supply from the battery 13a to the first receiver control circuit 81b, and the first receiver 81 is a remote controller. The signal sent from the transmitter R cannot be received (tenth step). When the power supply detection circuit 12 detects resumption of power supply from the external power supply, the charge control circuit 13 resumes charge control to the battery 13a (11th step). The charge control circuit 13 controls the charge monitor 88 to the lighting state according to the charge control of the charge control circuit 13 with the resumption of the charge control to the battery 13a (12th step). The seventh step to the twelfth step may be performed in any order.
The effect of Example 1 is demonstrated.
  The lighting apparatus 100 according to the first embodiment includes a first receiving unit that can receive a signal transmitted from the remote control transmitter R by supplying power from the battery 13a in a power supply stop state. Therefore, the safety light 86 can be controlled to be turned on by the remote control transmitter R, and even when the power switch SW provided between the external power source and the lighting device 100, for example, the wall switch is opened and the safety light 86 is turned on. The safety lamp 86 can be turned off by sending, for example, a light source turn-off signal and a nightlight turn-off signal from the remote control transmitter R.
  The lighting apparatus 100 according to the first embodiment includes a first receiving unit that can receive a signal transmitted from the remote control transmitter R by supplying power from the battery 13a in a power supply stop state. Therefore, the safety lamp 86 can be controlled to be lit by the remote control transmitter R, and the illuminance of the illumination space is ensured by other factors such as daytime when the external power supply has stopped supplying power. Even in this case, the safety light 86 can be turned off by sending a light source extinction signal, a nightlight extinction signal, or the like from the remote control transmitter R, for example.
  The lighting apparatus 100 according to the first embodiment includes a first receiving unit that can receive a signal transmitted from the remote control transmitter R by supplying power from the battery 13a in a power supply stop state. Therefore, the safety light 86 can be controlled to be turned on by the remote control transmitter R. Even when the safety light 86 is once turned off, the remote control transmitter R can transmit the all-light lighting signal, the nightlight lighting signal, etc. The lamp 86 can be turned on.
  The lighting device 100 according to the first embodiment includes the power supply detection circuit 12 in the power supply return state, so that it is possible to detect the resumption of power supply from the external power source to the lighting device 100. The accompanying safety light 86 is turned off, the power supply to the first receiver 81 is stopped (the first receiver 81 is incapable of receiving a signal transmitted from the remote control transmitter R), and the charging control circuit 13 Resumption of charging control for the battery 13a can be automatically performed without a special operation by the user of the lighting device 100.
  In addition, the lighting device 100 according to the first embodiment includes the power supply detection circuit 12 in the power supply return state, so that it is possible to detect the resumption of power supply from the external power source to the lighting device 100. It is possible to minimize the discharge of 13a and suppress the deterioration of the battery 13a. Furthermore, since the charging control to the battery 13a can be resumed immediately after the power supply is resumed, the time until the battery 13a is charged up to the maximum allowable charging capacity of the battery 13a can be shortened.
  In the illumination device 100 of the first embodiment, the power supply unit 2 includes a power supply detection circuit 12, a charge control circuit 13, a battery 13a, a first receiver control circuit 81b, and an auxiliary light source lighting control circuit for controlling lighting of the safety lamp 86. 86b is disposed separately from the light source lighting circuit 11, the second receiver control circuit 84b, and the nightlight lighting control circuit 85b for controlling the lighting of the light source unit 6, thereby controlling the lighting of the existing light source unit 6. A function for controlling the lighting of the safety lamp 86 can be added only by adding the configuration of the auxiliary component unit 8 to the light source lighting circuit 11, the second receiver control circuit 84b, and the nightlight lighting control circuit 85b. In addition, the power supply detection circuit 12, the charging control circuit 13, the battery 13a, the first receiver control circuit 81b, and the auxiliary light source for controlling the lighting of the safety lamp 86 between lighting devices having different specifications of the power supply unit 2 and the light source unit 6 are provided. The lighting control circuit 86b can be shared.
  The illumination device 100 according to the first embodiment receives power from the second receiver 84 and the battery 13a in a state in which a signal from the remote control transmitter R can be received in the external power supply state. By having the first receiving unit 81 that can receive a signal to be transmitted, an external power supply can be supplied by one remote control transmitter R without changing the signal transmitted from the remote control transmitter R. It is possible to control the lighting of the light source unit 6 and the nightlight 85 or the security lamp 86 in the stopped state.
  In the auxiliary component unit 8 of the lighting device 100 according to the first embodiment, whether the nightlight 85 of the lighting device 100 is controlled to be turned on by an external power supply by making the illuminance of the safety light 86 larger than the illuminance of the nightlight 85, As the safety light 86 is turned off by the power supply of the battery 13a when the supply of external power is stopped, it becomes easy to determine whether the user of the lighting device 100 can perform a desired operation.
  In the auxiliary component unit 8 of the lighting device 100 of the first embodiment, the night light 85 of the lighting device 100 is controlled to be turned on by external power supply by making the color temperature of the safety light 86 larger than the color temperature of the night light 85. However, since it becomes easy to determine whether the safety light 86 is controlled to be lit by the power supply of the battery 13a when the supply of external power is stopped, it is possible for the user of the lighting device 100 to easily perform a desired operation. .
  In the auxiliary component unit 8 of the lighting device 100 according to the first embodiment, the color temperature of the safety light 86 is made larger than the color temperature of the night light 85, so that the user of the lighting device 100 uses a light source having a higher color temperature. Since it feels brighter, the power of the battery 13a can be used more efficiently.
  Since the illumination device 100 according to the first embodiment includes the auxiliary light source dimming circuit 86c, the dimming control of the safety lamp 86 can be performed in the power supply stop state. Therefore, if the illuminance of the safety lamp 86 is reduced. The power consumption of the battery 13a can be reduced, and the lighting time of the safety light 86 can be made longer. Moreover, since the user of the illuminating device 100 can carry out dimming control of the security lamp 86 according to a use condition, a user's freedom degree increases.
  Since the lighting device 100 according to the first embodiment includes the battery voltage detection circuit 13b and the auxiliary light source dimming circuit 86c, the light output of the safety light 86 is reduced as the battery voltage decreases. It is possible to lengthen the lighting time and prevent the battery 13a from being overdischarged, thereby extending the life of the battery 13a. Alternatively, the progress of the deterioration of the battery 13a can be moderated.
  When the lighting device 100 according to the first embodiment performs dimming control on the safety lamp 86 according to the battery voltage, even if the dimming control signal is transmitted from the remote control transmitter R, the dimming control based on the battery voltage has priority. Therefore, even if control for increasing the light output from the remote control transmitter R is performed, the auxiliary light source lighting control circuit 86b or the auxiliary light source dimming circuit 86c does not increase the light output of the safety light 86. The overdischarge of the battery 13a can be prevented, and the life of the battery 13a can be extended. Alternatively, the progress of the deterioration of the battery 13a can be moderated.
The lighting device 100 according to the first embodiment can dimm and control the safety lamp 86 according to the battery voltage, and can control the turning-off of the remote control transmitter R. Can be long. Alternatively, the progress of the deterioration of the battery 13a can be moderated.
A modification of the first embodiment will be described below.
  In the illumination device 100, the auxiliary light source lighting control circuit 86b has a time measuring circuit for measuring the lighting time of the unillustrated safety light 86.
  The operation of the lighting device 100 will be described.
  When the lighting of the safety light 86 is started in the power supply stop state, the timing circuit starts measuring the lighting time. The auxiliary light source lighting control circuit 86b has a first lighting time, a second lighting time, a third lighting time, and a fourth lighting time as shown in FIG.
  As shown in FIG. 6 (b), the auxiliary light source lighting control circuit 86b compares the timing time input from the timing circuit with the threshold value of the lighting time, and when the lighting time reaches the first lighting time, the auxiliary light source lighting control circuit 86b The light source dimming circuit 86c is instructed to change the light output from the light output A to the light output B. The auxiliary light source dimming circuit 86c performs dimming control of the safety lamp 86 by PWM (pulse width modulation) control based on an instruction from the auxiliary light source lighting control circuit 86b. Thereafter, the auxiliary light source dimming circuit 86c reduces the light output in the order of the light output B, the light output C, and the light output D as the safety lamp 86 is turned on. The auxiliary light source dimming circuit 86c has a light output A, a light output B, a light output C, and a light output D as shown in FIG. .
  As shown in FIGS. 6 (a) and 6 (b), the auxiliary light source lighting control circuit 86b is configured such that the lighting time of the safety lamp 86 exceeds the first lighting time or the battery voltage exceeds the first battery voltage. In any one of the cases where it falls below, the light output of the safety lamp 86 is reduced from the light output A to the light output B. Thereafter, based on the battery voltage or the lighting time of the safety light 86, the light output is reduced in order of the light output B, the light output C, and the light output D.
  When dimming control of the safety lamp 86 according to the battery voltage, the dimming control from the remote control transmitter R is invalidated, and only the lighting and extinguishing control from the remote control transmitter R can be performed. It may be.
  The illuminating device 100 includes the auxiliary light source dimming circuit 86c and the timing circuit in the auxiliary light source lighting control circuit 86b, and the battery voltage detection circuit 13b or the timing in the charging control circuit 13 by including the battery voltage detection circuit 13b. If either one of the circuits operates, the light output of the safety light 86 can be reduced, so that the lighting time of the safety light 86 can be lengthened and the overdischarge of the battery 13a can be prevented more reliably. .
  A lighting apparatus 101 according to a second embodiment of the present invention will be described with reference to the drawings. Moreover, the same code | symbol is attached | subjected to the same part and the overlapping description is abbreviate | omitted. The circuit configuration and operation of the lighting device 101 will be described. FIG. 7 is a configuration diagram illustrating a circuit configuration of the illumination device 101 according to the second embodiment.
  A circuit configuration of the illumination apparatus 101 according to the second embodiment of the present invention will be described with reference to FIG.
  A first power supply detection circuit 12 a is connected in series between the adapter A and the charging control circuit 13. A second power supply detection circuit 12 b is connected in series between the adapter A and the light source lighting control circuit 11. Other circuit configurations are the same as those of the lighting apparatus 100 according to the first embodiment.
  The operation of the lighting device 100 will be described with reference to FIGS.
  An operation of the lighting apparatus 101 in the power supply stop state will be described. The first power supply detection circuit 12a and the second power supply detection circuit 12b have a predetermined time, for example, 1.5 seconds as a threshold value.
  When the power supply stop state is longer than a predetermined time of 1.5 seconds, the first power supply detection circuit 12a detects the power supply stop state and turns on the power stored in the battery 13a in the charge control circuit 13 to turn on the auxiliary light source. The control circuit 86b and the first receiver control circuit 81b are instructed to supply (13th step). The charge control circuit 13 controls lighting of the charge monitor 88 with the end of the charge control, that is, the start of the discharge control (14th step). In the power supply stop state, the charge monitor 88 is preferably turned off by the charge control circuit 13 in order to reduce the power consumption of the battery 13a. When the first receiver control circuit 81b is supplied with power from the battery 13a, the first receiver 81 is ready to receive a signal sent from the remote control transmitter R (fifteenth step). The auxiliary light source lighting control circuit 86b turns on the safety lamp 86 when power is supplied from the battery 13a (step 16). The thirteenth to sixteenth steps can be performed in any order. On the other hand, when the power supply stop state is 1.5 seconds or less of the predetermined time, the operations of the thirteenth to sixteenth steps are not performed.
  When the power supply stop state is longer than the predetermined time of 1.5 seconds, the power supply to the second power supply detection circuit 12b and the second receiver control circuit 84b is stopped. The signal sent from the remote control transmitter R cannot be received. Therefore, in the power supply stop state, the light source unit 6 and the nightlight 85 cannot be controlled to be turned on. If the light source unit 6 has been turned on or dimmed before the power supply is stopped, or if the nightlight 85 has been turned on or dimmed, the light source unit 6 and the nightlight 85 are turned off.
When the power supply stop state is 1.5 seconds or less of the predetermined time and the power supply stop state shifts from the power supply stop state to the power supply return state after 1.5 seconds or less, the second power supply detection circuit 12b The light source lighting control circuit 11, the dimming control circuit 11a, or the nightlight lighting control circuit 85b is instructed to control the lighting of the light source unit 6 or the nightlight 86 in the lighting control state of the light source unit 6 or the nightlight 86 different from that before the power supply is stopped. . For example, in the case where the light source unit 6 is all lighted before the power supply is stopped, the second power supply detection circuit 12b causes the light source to move from the power supply stop state for a predetermined time or less to the power supply return state. The lighting control circuit 11 and the dimming control circuit 11a are instructed to control the lighting of the light source unit 6 in a predetermined dimming state (21st step). For example, when the light source unit 6 is controlled to be lit in a predetermined dimming state before the power supply is stopped, the second power supply detection circuit 12b is in a power supply return state from the power supply stop state for a predetermined time or less. With the shift to, the nightlight lighting control circuit 85b is instructed to control lighting of the nightlight 85 in a predetermined dimming state or all-lighting state (step 22). Furthermore, for example, when the night-light 85 is controlled to be turned on in a predetermined dimming state or all-lighting state before the power supply is stopped, the second power supply detection circuit 12b is in a power supply stop state for a predetermined time or less. Along with the transition to the power supply return state, the nightlight lighting control circuit 85b is instructed to control the lighting of the nightlight 85 in the off state (23rd step). The 21st to 23rd steps are not limited to the order of control. Further, the 21st step includes control in the reverse direction. That is, when the light source unit 6 is controlled to be lit in a predetermined dimming state before the power supply is stopped, the second power supply detection circuit 12b switches from the power supply stop state for a predetermined time or less to the power supply return state. Along with the transition, this includes instructing the light source lighting control circuit 11 and the dimming control circuit 11a to perform lighting control of the light source unit 6 in a predetermined all-light lighting state. The same applies to the 22nd step and the 23rd step.
The effect of Example 2 will be described.
  Since the lighting apparatus 101 of the second embodiment includes the first power supply detection circuit 12a and the second power supply detection circuit 12b, the first power supply detection circuit 12a is used when the power supply stop state is longer than a predetermined time. When the operation of starting the lighting control of the safety light 86 is started and the power supply is stopped from the power supply stop state for a predetermined time or less, the second power supply detection circuit 12b detects the light source unit 6 or the night light 85. Therefore, even when the light source unit 6 or the nightlight 85 is controlled by a power switch such as a wall switch, the safety lamp 86 is not controlled to be lit. Therefore, undesired discharge and charge of the battery 13a can be prevented, and deterioration of the battery 13a can be suppressed. Further, the safety light 86 is not turned on and off inadvertently during the lighting control when the lighting control of the light source unit 6 or the nightlight 85 is performed by a power switch such as a wall switch.
  A charging control device 130 and a lighting device 102 according to a third embodiment of the present invention will be described with reference to the drawings. Moreover, the same code | symbol is attached | subjected to the same part and the overlapping description is abbreviate | omitted. The circuit configuration and operation of the charging control device 130 will be described. FIG. 8 is a configuration diagram illustrating a circuit configuration of the charging control apparatus 130 according to the third embodiment.
  A circuit configuration of the charging control apparatus 130 according to the third embodiment of the present invention will be described with reference to FIG.
  The first charging control circuit 13b that charges the battery with the first charging current value and the second charging control circuit 13c that charges the battery with the second charging current value larger than the first charging current value are connected in parallel to the external power source. The first charge control circuit 13b and the second charge control circuit 13c are each connected in series to the battery 13a. The first charge control detection circuit 13e is connected in series between the first charge control circuit 13b and the battery 13a. The battery 13a and the load are connected in series via the discharge time detection circuit 13d.
  The operation of the charging control device 130 will be described.
  In the external power supply state, the battery 13a is charge-controlled by the first charge control circuit 13b. The first charging control circuit 13b is charged at a first charging current value, for example, a current value of about 1/100 C per hour when the battery capacity is C [mAh]. The first charging current value is sufficient to compensate for the self-discharge of the battery 13a. When the charging capacity C of the battery 13a is 700 [mAh], the first charging current value is about 7 [mA]. When the battery 13a is charge-controlled by the first charge control circuit 13b, the first charge current value is desirably as small as possible from the viewpoint of reducing standby power of the charge control device 130.
  The charging control time for the battery 13a by the first charging control circuit 13b is measured by the first charging control detection circuit e. When the charging control time becomes equal to or longer than the first predetermined time, the first charging control detection circuit e instructs the second charging control circuit 13c described later to perform charging control of the battery 13a for a third predetermined time. In the present embodiment, the first predetermined time is about one week, and the third predetermined time is about 6 hours. Even if there is no discharge from the battery 13a to the load, the electric power stored in the battery 13a by the self-discharge gradually decreases. Therefore, when the charging control to the battery 13a by the first charging control circuit 13b continues for about one week, The amount of electric power stored in the battery 13a is maximized by charge control of the battery 13a by the two-charge control circuit 13c. That is, during the first predetermined time, even if the charging control to the battery 13a by the first charging control circuit 13b is continued, the amount of power stored in the battery 13a is reduced to the extent that the power supply from the battery 13a to the load is hindered. It is determined based on the decreasing time. In addition, the third predetermined time is for recovering the electric energy reduced from the battery 13a by the self-discharge in the first predetermined time to the maximum electric energy that can be stored in the battery 13a even if there is no discharge from the battery 13a to the load. Determined based on time.
  In the power supply stop state, the battery 13a is discharged to the load. When discharging from the battery 13a to the load, the discharge time detection circuit 13d measures the discharge time. When the discharge time is continuously equal to or longer than the second predetermined time, or when the discharge time is accumulated and becomes equal to or longer than the second predetermined time, the discharge time detection circuit 13d is operated by a second charge control circuit 13c described later. An instruction is given to perform charging control of the battery 13a for a third predetermined time. In the present embodiment, the second predetermined time is about 10 minutes. The second predetermined time is determined based on the charge capacity C of the battery 13a and the power consumption of the load. When the discharge time detection circuit 13d causes the discharge time to exceed the second predetermined time, the second charging control circuit 13c may immediately control the charging of the battery 13a, or stop discharging from the battery 13a to the load. Then, the charging control of the battery 13a by the second charging control circuit 13c may be started after elapse of a certain time.
  In the charging control of the battery 13a by the second charging control circuit 13c, charging is performed at a second charging current value, for example, a current value of about 1 / 5C per hour. When the charging capacity C of the battery 13a is 700 [mAh], the second charging current value is about 120 to 140 [mA]. The charging control of the battery 13a by the second charging control circuit 13c is performed in order to compensate for the self-discharge of the battery 13a within the first predetermined time, or to compensate for the reduction in the amount of power stored in the battery 13a due to the discharging. The power amount stored in the battery 13a is recovered to the maximum power amount that can be stored in the battery 13a.
  When the charging control of the battery 13a is performed by the second charging control circuit 13c, all the time information that has been measured in the discharging time detection circuit 13d and the first charging control detection circuit e is erased, and the second charging control circuit 13c. After the charging control of the battery 13a is completed, the time measurement is started again.
  The instruction to the second charge control circuit 13c by the discharge time detection circuit 13d and the instruction to the second charge control circuit 13c by the first charge control detection circuit e are performed independently. That is, when the time measured in the discharge time detection circuit 13d and the first charge control detection circuit e becomes the second predetermined time and the first predetermined time, respectively, the second charge is performed regardless of the other time measurement. The control of the battery 13a is performed by the control circuit 13c.
  The circuit configuration and operation of the illumination device 102 according to the third embodiment will be described with reference to the drawings. FIG. 9 is a configuration diagram illustrating a circuit configuration of the illumination device 102 according to the third embodiment. The circuit configuration of the illumination device 102 according to the third embodiment will be described with reference to FIG.
  The lighting device 102 includes a charging control device 130 instead of the charging control circuit 13 of the lighting device 100 according to the first embodiment. Other configurations are the same as those of the lighting device 100, and the lighting device 102 can perform the same operation as the lighting device 100 in addition to the operation of the charging control device 130.
The charging control device 130 is in a lighting control state of the charging monitor 88 connected to the charging control device 130 by the charging control state of the battery 13a by the first charging control circuit 13b and the charging control state of the battery 13a by the second charging control circuit 13c. Can be varied. For example, when the charging control of the battery 13a is performed by the second charging control circuit 13c, the charging monitor 88 is controlled to be turned on, and when the charging control of the battery 13a is performed by the first charging control circuit 13b, the charging monitor 88 is turned off. desirable. This is because the charge control time for the battery 13a by the first charge control circuit 13b is longer than the charge control time for the battery 13a by the second charge control circuit 13c, and therefore the battery 13a by the first charge control circuit 13b. This is because the power consumption of the lighting device 102 increases when the lighting monitor 88 is controlled to be turned on in the charging control.
The effect of Example 3 will be described.
  The charging control device 130 and the lighting device 102 according to the third embodiment include the first charging control circuit 13b, the second charging control circuit 13c, the discharging time detection circuit 13d, and the first charging control detection circuit 13e. Since the second charging control circuit can charge the battery when the charging time measured by the charging control detection circuit is equal to or longer than the first predetermined time or the discharging time counted by the discharging time detection circuit is equal to or longer than the second predetermined time, Charge control with a large current is not performed undesirably, and standby power can be reduced in an external power supply state. In addition, when the power stored in the battery 13a decreases, the charging control of the battery 13a is performed by the second charge control circuit 13c, so that the maximum amount of power stored in the battery 13a can be stored in the battery 13a. It is possible to shorten the time for recovering to the amount of electric power, and to improve the reliability of power supply to the load in the power supply stop state.
In the charging control device 130 and the lighting device 102 according to the third embodiment, when the charging control of the battery 13a is performed by the second charging control circuit 13c, the charging monitor 88 is controlled to be turned on, and the battery 13a is charged by the first charging control circuit 13b. Since the charging monitor 88 is turned off during the control, the charging monitor 88 is controlled in the charging control to the battery 13a by the first charging control circuit 13b, which is performed for a time longer than the charging control time of the battery 13a by the second charging control circuit 13c. An increase in power consumption of the charging control device 130 and the lighting device 102 due to the lighting control can be suppressed.
A modification of the third embodiment will be described below.
  In the charging control device 130 and the lighting device 102 according to the third embodiment, the first charging control detection circuit 13e measures the time for charging the battery 13a by the first charging control circuit 13b, and the first charging control detection circuit 13e measures the time. In a case where the measured time is equal to or longer than the fourth predetermined time, the user of the charge control device 130 and the lighting device 102 may be notified of the replacement time of the battery 13a by controlling the lighting of the charge monitor 88. When notifying the replacement time of the battery 13a by the charge monitor 88, it is desirable that the charge control state for the battery 13a by the first charge control circuit 13b and the charge control state for the battery 13a by the second charge control circuit 13c are different. . That is, the charging control state of the battery 13a by the second charging control circuit 13c is notified by turning on the charging monitor 88, and the charging control state to the battery 13a by the first charging control circuit 13b is turned off by turning off the charging monitor 88. It is desirable to make the charging monitor 88 blink when informing and notifying the replacement time of the battery 13a. By changing the lighting state of the charge monitor 88, the user of the charge control device 130 and the lighting device 102 can be surely notified of the replacement time of the battery 13a, and can be urged to replace the battery 13a. The notification by the lighting control of the charge monitor 88 when the battery 13a is replaced may be stopped by the remote control transmitter R, or may be automatically turned off after a predetermined time.
  After the replacement of the battery 13a, the charge control time to the battery 13a by the first charge control circuit 13b of the first charge control detection circuit 13e is reset by operating the remote control transmitter R in the external power supply stop state. . After the battery 13a is replaced, the charging control of the battery 13a is performed by the second charge control circuit 13c, the remote control transmitter R is operated when the external power supply is stopped, and the timed time reset signal is sent from the remote control transmitter R. The first receiving unit 81 receives the timekeeping time reset signal, and the first receiving unit control circuit 81b is connected to the first charging control detection circuit 13e of the charging control device 130 by the first charging control circuit 13b of the first charging control detection circuit 13e. An instruction is given to reset the time for controlling the charging of the battery 13a. It may be notified by lighting control of the charge monitor 88 that the charging time is reset after the charging time is reset.
  A lighting apparatus according to Embodiment 4 of the present invention will be described with reference to the drawings. Moreover, the same code | symbol is attached | subjected to the same part and the overlapping description is abbreviate | omitted.
  The auxiliary component unit 8 of the lighting apparatus according to the fourth embodiment of the present invention will be described with reference to FIG.
  In the present embodiment, the switch 87 of the auxiliary component unit 8 is used to distinguish each lighting device when a plurality of lighting devices are provided within a range in which a signal transmitted from the remote control transmitter R can be received. Multiple channels can be switched. The remote control transmitter R is provided with a channel switch so that a plurality of lighting devices can be selected and controlled.
  In this embodiment, the case where the switch 87 has channel 1 and channel 2 will be described. In this case, two lighting devices are provided within a range in which a signal transmitted from the remote control transmitter R can be received. One lighting device has the switch 87 set to channel 1 and the other lighting device has the switch 87. Channel 2 is set. When operating the lighting device set to channel 1 by the remote control transmitter R, the channel change switch is set to channel 1 for operation. Similarly, when the lighting device set to channel 2 is operated by the remote control transmitter R, the channel change switch is set to channel 2 for operation.
  The channel setting of the switch 87 is sent as channel setting information to the second receiver control circuit 84 b connected to the switch 87.
  In the external power supply state, the lighting device set to channel 1 and the lighting device set to channel 2 can perform the same operations as those described in the first embodiment. For example, when the channel selector switch of the remote control transmitter R is set to channel 1 and the remote control transmitter R is operated so that the light source unit 6 of the lighting device set to channel 1 is turned on all the lights, A channel 1 signal is sent out as a light lighting signal and a signal based on the fact that the channel selector switch is set to channel 1, that is, a channel signal.
  The all-light lighting signal and the channel 1 signal transmitted from the remote control transmitter R are received by the second receiving unit 84 of the lighting device set to channel 1 and the second receiving unit 84 of the lighting device set to channel 2, respectively. Is done.
  In each lighting device, the all-light lighting signal and the channel 1 signal are sent to the second receiver control circuit 84b (31st step). Each lighting device checks whether or not the channel signal matches the channel setting information set by the switch 87 by the channel information comparison circuit provided in the second receiver control circuit 84b (step 32). The channel information comparison circuit sends a signal based on the all-light lighting signal to the light source lighting circuit 11 only when the channel signal matches the channel setting information (step 33). The light source lighting circuit 11 is controlled to be turned on by a signal based on the all-light lighting signal, and the lighting state of the light source unit 6 is changed (step 34). Note that the 31st to 34th steps are not limited to the order of control.
  Whether or not the channel signal is added to the signal transmitted from the remote control transmitter R, and whether or not the channel signal matches the channel setting information set by the switch 87 by the channel information comparison circuit provided in the second receiver control circuit 84b. By being confirmed, even when a plurality of illumination devices are provided within a range in which a signal transmitted from the remote control transmitter R can be received, only an arbitrary illumination device can be controlled.
  On the other hand, in the power supply stop state, the lighting device set to channel 1 and the lighting device set to channel 2 can perform the same operations as those described in the first embodiment. For example, when the channel selector switch of the remote control transmitter R is set to channel 1 and the remote control transmitter R is operated so that the security lamp 86 as the auxiliary light source of the lighting device set to channel 1 is turned off, the remote control transmitter R Transmits a light source extinction signal and a channel 1 signal.
  The light source extinguishing signal and the channel 1 signal sent from the remote control transmitter R are respectively received by the second receiving unit 84 of the lighting device set to channel 1 and the second receiving unit 84 of the lighting device set to channel 2. The
  In each lighting device, the light source extinction signal and the channel 1 signal are sent to the first receiver control circuit 81b (35th step). The first receiver control circuit 81b of each lighting device sends a signal based on the light source extinction signal to the auxiliary light source lighting control circuit 86b regardless of the channel signal (step 36). In each lighting device, the auxiliary light source lighting control circuit 86b is controlled to be turned on by a signal based on the light source extinguishing signal, the lighting state of the safety light 86 is changed, and the safety light 86 is turned off (step 37). Note that the 35th to 37th steps do not matter in the order of control.
After the channel signal is added to the signal transmitted from the remote control transmitter R and received by the first receiver 81, the first receiver control circuit 81b is controlled by the first receiver control circuit 81b regardless of the channel signal. The auxiliary light source lighting circuit 86b is instructed to be controlled based on the signal sent from the transmitter R. Therefore, in the power supply stop state, the remote control transmitter R can control the lighting of the safety light 86 as an auxiliary light source regardless of the channel setting of the switch 87 and the channel setting of the remote control transmitter R.
The effect of Example 4 will be described.
  In the illumination device of the fourth embodiment, the first receiver control circuit 81b does not compare the channel setting information based on the channel setting of the switch 87 with the channel signal based on the setting of the channel switch of the remote control transmitter R. Without switching the setting of the channel selector switch of the remote control transmitter R, it is possible to simultaneously operate a plurality of lighting devices provided within a range in which a signal transmitted from the remote control transmitter R can be received. In addition, when the safety light 86 is turned on undesirably, lighting control such as turning off can be easily performed, so that the power consumption of the battery 13a can be reduced, and standby power associated with the charging control of the battery 13a of the lighting device can be reduced. Can be reduced.
  An illumination apparatus according to Embodiment 5 of the present invention will be described with reference to the drawings. Moreover, the same code | symbol is attached | subjected to the same part and the overlapping description is abbreviate | omitted. The illumination device of Example 5 has a circuit configuration similar to that of the illumination device 100 shown in FIG.
  Operation | movement of the illuminating device of Example 5 is demonstrated.
  The lighting device of the fifth embodiment is different in the operation of the sixth step of the lighting device 100 of the first embodiment. In the illumination device of the fifth embodiment, even if power is supplied from the battery 13a to the auxiliary light source lighting control circuit 86b, the safety lamp 86 is not turned on simultaneously with the power supply from the battery 13a, and the first receiver control circuit 81b. (Step 41). The signal sent from the remote control transmitter R is received by the first receiver 81 and sent to the first receiver control circuit 81b (step 42). Based on the signal received by the first receiver 81, the first receiver control circuit 81b instructs the auxiliary light source lighting control circuit 86b to control lighting of the safety lamp 86 as an auxiliary light source (step 43). In addition to the third to fifth steps of the lighting device 100 of the first embodiment, the lighting device of the fifth embodiment starts lighting control of the safety lamp 86 by the operations of the 41st to 43rd steps. Note that the third step to the fifth step, and the 41st step to the 43rd step do not matter in the order of control.
That is, the lighting device of the fifth embodiment does not start the lighting control of the safety light 86 only because the power supply is stopped, and a signal is transmitted from the remote control transmitter R or the remote control transmitter R. When the first receiver 81 receives the signal sent from the, the lighting control of the safety light 86 is started.
The effect of Example 5 will be described.
  The lighting device of the fifth embodiment does not start the lighting control of the safety light 86 only because the power supply is stopped, and a signal is transmitted from the remote control transmitter R or transmitted from the remote control transmitter R. When the first signal is received by the first receiving unit 81, the lighting control of the safety light 86 is started, so that the safety light 86 as an auxiliary light source is undesirably controlled without being operated by the remote control transmitter R. Therefore, the power consumption of the battery 13a can be reduced, the lighting time of the safety light 86 can be extended, and the reliability of the safety light 86 can be expected to be improved. In addition, since the safety lamp 86 is not undesirably controlled, power consumption associated with the charging control of the battery 13a can be reduced. Furthermore, the charge control and discharge cycle of the battery 13a can be reduced, and deterioration of the battery 13a can be suppressed.
  Example 6 Illuminating device of the present invention will be described with reference to the drawings. Moreover, the same code | symbol is attached | subjected to the same part and the overlapping description is abbreviate | omitted. The illuminating device of Example 6 has the same circuit configuration as the illuminating device 100 shown in FIG. 5, the illuminating device 101 shown in FIG. 7, or the illuminating device 102 shown in FIG.
  In the illuminating devices 100 to 102, the auxiliary light source lighting control circuit 86b is provided with a timing circuit that counts the lighting time of the security lamp 86 (not shown). Further, for example, as shown in FIG. 5, an auxiliary light source dimming circuit 86c is provided in the auxiliary light source lighting control circuit 86b.
  Operation | movement of the illuminating device of Example 6 is demonstrated.
  When the lighting of the safety light 86 is started in the power supply stop state, the timing circuit starts measuring the lighting time. The auxiliary light source lighting control circuit 86b has a first lighting time, a second lighting time, a third lighting time, and a fourth lighting time as shown in FIG.
  As shown in FIG. 6 (b), the auxiliary light source lighting control circuit 86b compares the timing time input from the timing circuit with the threshold value of the lighting time, and when the lighting time reaches the first lighting time, the auxiliary light source lighting control circuit 86b The light source dimming circuit 86c is instructed to change the light output from the light output A to the light output B. The auxiliary light source dimming circuit 86c performs dimming control of the safety lamp 86 so that the light output of the safety lamp 86 becomes the light output A based on the instruction of the auxiliary light source lighting control circuit 86b. The auxiliary light source dimming circuit 86c controls the safety lamp 86 by PWM (pulse width modulation) control. Thereafter, the auxiliary light source dimming circuit 86c reduces the light output in the order of the light output B, the light output C, and the light output D as the safety lamp 86 is turned on. The auxiliary light source dimming circuit 86c has a light output A, a light output B, a light output C, and a light output D as shown in FIG. .
  For example, the illuminance can be decreased by 20 lm every 30 minutes after the safety light 86 is turned on. At this time, the difference between the first lighting time and the second lighting time is determined as 30 minutes, and the difference between the light output A and the light output B is determined as 20 lm.
6B, the light output of the safety light 86 is decreased stepwise in a stepwise manner as the battery voltage decreases. However, it may be decreased in a slope shape at a constant reduction rate.
The effect of Example 6 will be described.
  The illuminating device 100 according to the sixth embodiment includes the auxiliary light source dimming circuit 86c in the auxiliary light source lighting control circuit 86b, so that the illuminance of the safety lamp 86 is changed according to the lighting time of the safety lamp 86 as the auxiliary light source. Since the power consumption of the battery 13a is reduced in the power supply stop state, the lighting time of the safety light 86 can be made longer. In addition, by changing the illuminance of the safety light 86 according to the lighting time of the safety light 86, it is possible to notify the user of the lighting device 100 that the amount of power stored in the battery 13a is decreasing.
