An example of the illuminance directly below the night light is 0.5 Lx or more and less than 5 Lx. Furthermore, low color temperature lights around 2700K are preferred as night lights.

The luminaire 20 includes a first light source 21 that emits main illumination and a night light, a second light source 22 that emits a night light, a first lighting circuit 23 that supplies power to the first light source 21, and the second light source 22. and a second lighting circuit 24 for supplying power. The lighting fixture 20 also includes a control section 25 that controls lighting states of the first light source 21 and the second light source 22 . Although details will be described later, when an operation signal based on a night light lighting operation is received from the remote controller 30, the control unit 25 outputs a night light lighting command to the second lighting circuit 24, and outputs a night light lighting command to the first lighting circuit 24. It is configured to output to the lighting circuit 23 . The night light turn-on command is a control signal for turning on the night light, and the night light turn-on command is a control signal for turning on the night light.

The remote controller 30 includes a plurality of operation buttons, a remote control section that generates an operation signal based on the operation of the operation button, and a transmission section that transmits the operation signal to the lighting device 20 (all not shown). A remote controller 30 includes, as operation buttons, an all-light button 31 for turning on the main lighting, a night-light button 32 for turning on the night light, a turn-off button 33 for turning off the lighting light source, and a night-light button 34 for turning on the night light.

An operation signal output from the remote controller 30 is received by the receiver 26 of the lighting device 20 and processed by the controller 25 . By outputting the control signal generated by the control unit 25 to the first lighting circuit 23 and the second lighting circuit 24, the first light source 21 and the second light source 22 are turned on according to the operation of the remote controller 30. Become.

The lighting system illustrated in FIG. 1 includes, in addition to the lighting device 20, other devices that are operated by an operation signal (hereinafter referred to as “operation signal S1”) output from the remote control 30 based on the lighting operation of the night light. In FIG. 1, as the other devices, a corridor lighting fixture 4 installed in the corridor 2 and a toilet lighting fixture 5 installed in the toilet 3 are illustrated. The corridor lighting fixture 4 and the toilet lighting fixture 5 have a light source capable of emitting a night light, and turn on the night light when receiving the operation signal S1 directly or via another device. That is, in the lighting system illustrated in FIG. 1 , night lights are turned on in the bedroom 1 , corridor 2 , and toilet 3 by operating the remote control 30 .

Note that the device that operates based on the operation signal S1 is not limited to the lighting fixture illustrated in FIG. 1, and may be a device other than the lighting fixture. Also, the lighting device 20 may be the only device that operates based on the operation signal S1. The signal of the remote control 30 including the operation signal S1 may be transmitted by a short-range wireless communication method such as Bluetooth (registered trademark) communication, ZigBee (registered trademark) communication, or Wi-Fi (registered trademark) communication.

The lighting device 20 will be described in detail below with reference to FIGS. 2 to 6. FIG. 3 to 5 are diagrams for explaining the lighting modes of the night light.

The lighting fixture 20 is, for example, a ceiling light. The luminaire 20 comprises at least two types of light sources, including a first light source 21 that emits primary and night light, and a second light source 22 that emits a night light. The main lighting may be composed of a plurality of light sources with different color temperatures and may be color-tunable. A suitable light source is a semiconductor light-emitting element, and among them, an LED (Light Emitting Diode) is preferable. The first light source 21 and the second light source 22 may be composed of multiple LEDs. The lighting device 20 also includes the first lighting circuit 23, the second lighting circuit 24, the control section 25, and the receiving section 26, as described above. The receiver 26 includes a light receiving element such as a phototransistor, and receives a signal output from the remote control 30 .

The first lighting circuit 23 is a circuit that supplies power to the first light source 21 and includes semiconductor elements such as various resistance elements and capacitors. For the capacitor included in the first lighting circuit 23 (hereinafter referred to as "first capacitor"), for example, an electrolytic capacitor with a large time constant that can handle the output of the main lighting is used. As described above, when the night light is turned on, the power supplied to the first light source 21 is greatly reduced compared to when the main lighting is turned on. It may take a certain amount of time for the to light up.

The second lighting circuit 24 is a circuit that supplies power to the second light source 22, and, like the first lighting circuit 23, includes semiconductor elements such as various resistance elements and capacitors. For the capacitor included in the second lighting circuit 24 (hereinafter referred to as the "second capacitor"), for example, an electrolytic capacitor with a small time constant adapted to the output of the night light is used. That is, there is a relationship of time constant of the first capacitor>time constant of the second capacitor. Generally, the second capacitor is always in a state of being charged by the standby voltage applied to the second lighting circuit 24 . Therefore, when the night-light lighting command for lighting the night-light is output to the second lighting circuit 24, the night-light is immediately turned on.

The control unit 25 is configured to generate a control command based on the operation signal of the remote controller 30 acquired via the receiving unit 26 and output the control command to the first lighting circuit 23 and the second lighting circuit 24 . The lighting state of the first light source 21 is controlled via the first lighting circuit 23 and the lighting state of the second light source 22 is controlled via the second lighting circuit 24 by control commands generated and output by the control unit 25 . be. The control command includes a night-light lighting command to turn on the night-light and a night-light lighting command to turn on the night-light, which are generated based on the night-light lighting operation signal S1. The operation signal S1 is output from the remote control 30 when the night light button 34 is pressed.

The control unit 25 is composed of, for example, a microcomputer, and has a processor (CPU) as an arithmetic processing unit, a storage unit composed of RAM, ROM, etc., an input/output port, and the like. The CPU has a function of reading and executing a control program pre-stored in the storage unit. Generally, the functions of the control unit 25 are implemented by executing a control program. The storage unit has a function of temporarily storing information used for processing by the CPU, and a function of storing control programs, various setting information, and the like.

As described above, when receiving the operation signal S1 from the remote controller 30, the control unit 25 outputs a night light lighting command to the second lighting circuit 24 and outputs a night light lighting command to the first lighting circuit 23. is configured to That is, the control unit 25 receives the operation signal S1 for turning on the night light based on the operation of the night light button 34 as well as when receiving the operation signal for turning on the night light based on the operation of the night light button 32. A lighting command is output to light the second light source 22 for the night light.

For example, at time _t0 when the operation signal S1 is acquired via the receiving unit 26, the control unit 25 simultaneously outputs a night light turn-on command and a night light turn-on command. In the example shown in FIG. 3, a predetermined time lag (t ₁ -t ₀ ) occurs between the output of the night light turn-on command and the time t ₁ at which the night light turns on. The time lag (t ₁ -t ₀ ) is, for example, 0 to 3 seconds, and varies greatly depending on the elapsed time after the main illumination is turned off. If the main lighting has just been turned off, the first capacitor still has electric charge, so the night light may be immediately turned on by the output of the night light turn-on command. On the other hand, if a long time has passed since the main lighting was turned off, there is no charge left in the first capacitor, so it may take about 3 seconds from the output of the night light turn-on command to turn on. .

According to the lighting device 10, by including the above-described night-light lighting control means for turning on the night-light that starts quickly from the output of the night-light lighting command until the night-light is turned on, after the lighting operation of the night-light, It is possible to prevent the black state from continuing for a while (up to about 3 seconds). Since the night light is darker than the night light, even if the night light is turned on, the user is not awakened, and since the night light is turned on after the user gets used to the eyes with the night light, the awakening is further suppressed.

The control unit 25 is configured to output a night light turn-off command for turning off the night light at time _t2 after turning on the night light or after a predetermined time has passed since the output of the night light turn-on command. The control unit 25 may determine whether or not the night light is turned on using an illuminance sensor or the like, and output a night light turn-off command to the second lighting circuit 24 after turning on the night light. Alternatively, the predetermined time is set based on the maximum value of the assumed time lag (t ₁ -t ₀ ), and after the predetermined time has passed since the output of the night light turn-on command, the night light turn-off command is output to the second lighting circuit 24. may In either case, it is possible to prevent the night light from turning off before the night light is turned on.

When the controller 25 receives an operation signal for turning off the night light (hereinafter referred to as "operation signal S2") from the remote controller 30, it outputs a night light turn-off command for turning off the night light to the first lighting circuit 23. is configured to The operation signal S2 is output from the remote control 30, for example, when the light-off button 33 is pressed. The control unit 25 may output the night light extinguishing command together with the night light extinguishing command to extinguish the night light without automatically extinguishing the night light when receiving the operation signal S2. When the night light button 32 is pressed while the night light and the night light are on, only the night light extinguishing command may be output to extinguish only the night light. You may turn off the night light when

As illustrated in FIG. 4, if the night light is in a lighting state at the time when the lighting operation of the night light is performed, the lighting state of the night light may be continued. The control unit 25 is configured to maintain the lighting state of the night light regardless of the operation signal S1 when the night light is in the lighting state at time _t0 when the operation signal S1 is acquired. When the night light is in the lighting state at time _t0 when the operation signal S1 is acquired, the control unit 25 prohibits the output of the night light lighting command and the night light extinguishing command at time _t2 , and continues the lighting state of the night light. good too. In this case, when the night light button 32 is pressed, only the night light extinguishing command may be output to extinguish only the night light. Night lights may be turned off.

As illustrated in FIG. 5, the night light may be turned on at time t ₀ when the operation signal S1 is acquired, and then the night light turn-on command may be output after a predetermined waiting time (t ₃ −t ₀ ). That is, the control unit 25 may be configured to output the night light turn-on command at time _t3 after a predetermined time has elapsed since the output of the night light turn-on command. The standby time (t ₃ -t ₀ ) is set, for example, to the maximum value of the assumed time lag (t ₁ -t ₃ ) from the output of the night light turn-on command until the night light turns on. As described above, this time lag is not constant, so the night light may turn on at the same time as the night light turns on. Therefore, by setting the standby time, it is possible to reliably provide a time during which only the night light is turned on, so that the night light can be turned on after the eyes are accustomed to the night light.

FIG. 6 is a flowchart showing a control procedure for turning on the night light of the lighting device 10. As shown in FIG. A case where the night light button 34 is operated in the off state will be described below.

In the example shown in FIG. 6, when the operation signal S1 for turning on the night light based on the operation of the night light button 34 is acquired, the night light lighting command is output (S10, S11), and the second light source 22 which is the light source for the night light is output. lights up (S12). The control unit 25 acquires the operation signal S<b>1 transmitted from the remote controller 30 via the receiving unit 26 , generates a night light lighting command, and outputs the control command to the second lighting circuit 24 . The second light source 22 is immediately turned on by the output of the night light lighting command.

Next, on the condition that a predetermined time has passed since the acquisition of the operation signal S1, a night light lighting command is output (S13, S14). The light source 21 lights up with the brightness of a night light (S15). The control unit 25 outputs a night light lighting command to the first lighting circuit 23 after a predetermined period of time has elapsed since acquisition of the operation signal S1. Since the night light lighting command is output at the same time when the operation signal S1 is obtained, in other words, the night light lighting command is output after a predetermined time has elapsed since the night light lighting command was output.

Next, on the condition that a predetermined time has passed since the output of the night light turn-on command, a night light turn-off command is output (S16, S17), and the second light source 22 is turned off (S18). The control unit 25 outputs a night-light turn-off command to the second lighting circuit 24 after a predetermined time has passed since the output of the night-light turn-on command. The predetermined time is set to a time longer than the maximum value of the time lag that can occur in S15. In this case, the night light is automatically turned off after the night light is turned on. Note that at least one procedure of S13 and S16 to S18 may be omitted in the lighting control of the night light.

As described above, according to the lighting device 10, since the night light is immediately turned on by the night light lighting operation, it is possible to prevent the darkness from continuing for a while after the lighting operation. It is possible to alleviate the influence of the time lag from when the light is turned on until the night light is turned on. As described above, the control unit 25 includes automatic extinguishing means for automatically extinguishing the night light after the night light is turned on, and standby for setting a predetermined standby time after outputting the night light lighting command and before outputting the night light lighting command. At least one of the setting means is preferably provided.

It should be noted that the above-described embodiment can be appropriately modified in design within a range that does not impair the purpose of the present disclosure. For example, the remote controller may not have a dedicated night light button, and may be configured to turn on the night light using another operation button. Also, instead of the dedicated remote control 30, a mobile terminal such as a smart phone or a tablet may be used as a remote control.

Further, in the above-described embodiment, when the night light lighting operation is executed, a signal for lighting the night light (night light lighting command) is output, and a signal for lighting the night light (night light lighting command) is output. Although the controller 25 of the lighting fixture 20 is provided, the function of the controller may be provided in the remote controller. In this case, when the lighting operation of the night light is executed, the control unit of the remote controller outputs an operation signal for turning on the night light to the lighting equipment, and also outputs an operation signal for turning on the night light. Output.

Furthermore, the control section of the remote controller may have the same configuration as the control section 25 described above. For example, the control unit of the remote controller may output the operation signal for turning on the night light after a predetermined time has elapsed since the output of the operation signal for turning on the night light. Further, after turning on the night light or after a predetermined time has passed since the output of the operation signal for turning on the night light, the operation signal for turning off the night light may be output. Further, if the night light is in a lighting state at the time when the lighting operation of the night light is executed, for example, the output of the operation signal related to the night light may be prohibited to continue the lighting state of the night light.
