Unless otherwise specified, the explanations of the respective embodiments can be referred to each other's explanations.

[Embodiment 1]
FIG. 1 is a block diagram showing an example of the configuration of the lighting system of the present invention. As shown in FIG. 1, the lighting system of the present invention includes the remote controller 10 of the present invention and the luminaire 20 of the present invention.

(Remote controller)
First, the remote controller 10 will be described. The remote controller 10 has a signal transmitting unit 11 and a remote controller clock unit 12. The transmission unit 11 transmits a signal to the luminaire 20. The signal includes activation information of automatic control of the lighting fixture 20 and time information of the remote control clock unit 12. The remote controller 10 has, for example, a battery mounting portion, and can be driven by the battery by setting the battery in the battery mounting portion. The battery may be, for example, non-rechargeable or rechargeable.

The remote controller 10 may be similar to a conventionally known remote controller for lighting equipment having a clock function, except that, for example, the transmission unit 11 can transmit a signal including the auto control activation information and the time information. ..

The signal transmission format by the transmission unit 11 of the remote controller 10 is not particularly limited. Examples of the signal carrier include infrared rays and the like.

The remote control clock unit 12 may have a clock function indicating a so-called time. The time of the remote control clock unit 12 can be adjusted by, for example, an operator. For example, as described above, the remote controller 10 can be driven by the battery, and the remote controller clock unit 12 also has the clock function driven by the set battery. In the present invention, the "clock function" of the remote control clock unit 12 includes a function of indicating the time, and does not mean, for example, only a stopwatch function of indicating the elapsed time. The "clock function" of the remote control clock unit 12 in the present invention may include only the function of indicating the time, or may include both the function of indicating the time and the function of indicating the elapsed time.

FIG. 2 shows an example of the appearance of the remote controller 10. The remote controller 10 has a transmission unit 11 and a remote controller clock unit 12 inside. For example, as shown in FIG. 2, the remote controller 10 may further have a display unit 101 and buttons 102 to 104 for selecting and transmitting a signal to be transmitted to the luminaire 20. In the remote controller 10 of FIG. 2, the button 104 "comfort" is a button that selects the automatic control of the lighting fixture 20 and transmits a signal including the activation information of the automatic control and the time information of the remote controller clock unit 12. The button 102 "all lights" is, for example, a button for transmitting a signal for lighting all the lighting units 22 of the luminaire 20 instead of the automatic control, and the button 103 "turning off" is, for example, not the automatic control but the lighting. It is a button for transmitting a signal to turn off all the lighting units 22 of the fixture 20. In addition, in FIG. 2, the expression "comfort, all lights, extinguishing" is an example, and is not limited thereto.

The display unit 101 is, for example, a liquid crystal display or the like, and can display information such as the current time as indicated by reference numeral 101a.

Although only the three main buttons 102 to 104 are illustrated in the remote controller 10 of FIG. 2, for example, an adjustment button for manually adjusting the lighting color, brightness, etc. of the lighting fixture 20, and an extinguishing time are shown. It may have a button for setting the timer of. Further, the remote controller 10 may further have a cover 105, and the cover 105 may be, for example, a slide type that moves in the vertical direction, or an open / close type in which the upper portion of the cover 105 rises in the front direction in the drawing. .. The various buttons may be covered by, for example, a cover 105 when not in use.

(lighting equipment)
Next, the lighting fixture 20 will be described. The lighting fixture 20 includes a signal receiving unit 21, a lighting unit 22, a lighting control unit 23, a lighting clock unit 24, and a time correction unit 25.

The receiving unit 21 receives a signal from the transmitting unit 11 of the remote controller 10. The receiving unit 21 is the same as the signal receiving unit in the lighting equipment of the conventionally known remote control type lighting system, except that it receives, for example, a signal including the activation information of the auto control and the time information.

The lighting unit 22 includes, for example, one or more light emitting elements. Examples of the light emitting element include an LED (Light Emitting Diode), a fluorescent lamp, an organic EL (Electro Luminescence), an inorganic EL, a semiconductor laser, and the like, and are not particularly limited. As the lighting unit 22, for example, the same lighting unit as in a conventionally known lighting fixture can be used.

The illumination clock unit 24 may have a clock function indicating a so-called time. In the present invention, the "clock function" of the lighting clock unit 24 includes a function of indicating a time, and does not mean, for example, only a stopwatch function of indicating an elapsed time. The "clock function" of the lighting clock unit 24 in the present invention may include only a function of indicating a time, or may include both a function of indicating a time and a function of indicating an elapsed time. The correction unit 25 corrects the time of the lighting clock unit 24 based on the time information included in the signal received by the reception unit 21. The roles of the illumination clock unit 24 and the correction unit 25 in the present invention will be described below.

In a conventional remote control type lighting system, usually only the remote control has a clock function for indicating the time, and the lighting fixture does not have the clock function for indicating the time. In the conventional remote control type lighting system, for example, it can be turned on and off by a timer, but this is a function of indicating the elapsed time, that is, a stopwatch function, not a clock function of indicating the time. On the other hand, in the lighting system of the present invention, in addition to the remote control 10 having the remote control clock unit 12 indicating the time, the lighting fixture 20 also has the illumination clock unit 24 indicating the time. However, the power of the luminaire 20 can usually be turned off by the remote controller 10 or by the wall switch, but in the former case, the power is supplied to the luminaire 20 only by turning off the lighting unit 22. However, in the latter case, in addition to turning off the lighting unit 22, the supply of electric power to the luminaire 20 is also stopped. Therefore, in the former case, even if the power is turned off, the lighting clock unit 24 can drive the clock function by the electric power supplied to the lighting fixture 20, so that the lighting fixture 20 is turned off (lighting unit 22). Even if you turn off the light, you can still know the correct time. On the other hand, in the latter case, since the supply of electric power to the luminaire 20 is stopped by turning off the power, the illuminating clock unit 24 cannot drive the clock function, and for example, the time stops at that point. Therefore, in the lighting system of the present invention, as described above, the remote control 10 transmits a signal including the activation information of the automatic control of the lighting fixture 20 and the time information of the remote clock unit 12, and the lighting fixture 20 transmits the signal. Is received, and the time of the lighting clock unit 24 is corrected by the correction unit 25 based on the time information of the remote clock unit 12 included in the signal. As a result, even if the power of the lighting fixture 20 is turned off by the wall switch and the time of the lighting clock unit 24 is stopped, the power of the wall switch of the lighting fixture 20 is turned on again and the automatic control of the lighting fixture 20 is turned on. When set to, the time of the lighting clock unit 24 of the lighting fixture 20 can be corrected. As a method of maintaining the driving of the lighting clock unit 24 of the lighting equipment 20 even when the power is turned off by the wall switch, it is conceivable that the lighting equipment 20 has a battery or the like dedicated to the lighting clock unit 24. , This is not realistic. On the other hand, in the lighting system of the present invention, as described above, the time of the lighting clock unit 24 is corrected by the correction unit 25 based on the time information of the remote control clock unit 12 included in the signal received by the receiving unit 21. Will be done. Therefore, the lighting system of the present invention can easily correct the time without requiring a dedicated battery or the like.

The control unit 23 stores the lighting conditions according to the time, and automatically controls the lighting of the lighting unit 22 based on the lighting conditions and the time of the lighting clock unit 24. In this way, in the lighting system of the present invention, the control unit 23 can automatically control the lighting of the lighting unit 22 so that the lighting conditions are set according to the time of day. Further, according to the lighting system of the present invention, as described above, the lighting fixture 20 has the lighting clock unit 24 and corrects the time based on the time information of the remote control clock unit 12 included in the received signal. The correction unit 25 is provided. Therefore, for example, the lighting system of the present invention can correct the time that is the reference for the automatic control of lighting by the control unit 23 each time the auto control is driven, and can realize the lighting that matches the time.

The control unit 23 stores, for example, the time and the lighting condition in association with each other. Examples of the lighting condition include the presence / absence of lighting, the tint of light, the intensity of light, and the like. Lighting conditions according to the time of day include, for example, pale and bright light in the morning, relaxing colors in the evening, and dark light and extinguishing in the evening. When associating the time with the lighting condition, the method of dividing the time is not particularly limited, for example, morning and afternoon; early morning (for example, 0:00 to 3:00 am), dawn (3:00 am to 6:00 am). , Morning (6 am-9am), before noon (9 am-9pm), afternoon (noon-3pm), evening (3pm-6pm), early night (6pm-9pm) 9 o'clock), late at night (9 pm to 0 pm); etc., or may be set in hours or minutes.

The correction unit 25, the lighting clock unit 24, and the control unit 23 may be composed of, for example, a CPU (Central Processing Unit), a microprocessor, a microcontroller (microcomputer), a non-volatile memory, and the like.

Next, the automatic control by the lighting system of this example will be described with an example.

First, when the operator presses the comfort button 104 of the remote controller 10 shown in FIG. 2 while the wall switch is ON and power is being supplied to the luminaire 20, the luminaire 20 is transmitted from the transmitter 11 of the remote controller 10. A signal including the activation information of the automatic control and the time information of the remote control clock unit 12 is transmitted to the luminaire 20, and the reception unit 21 of the illuminator 20 receives it. As shown in FIG. 2, when the comfort button 104 of the remote controller 10 is pressed, "comfort" (reference numeral 101b) may be displayed on the display unit 101 of the remote controller 10.

When the receiving unit 21 receives the signal in the lighting fixture 20, the correction unit 25 corrects the time of the lighting clock unit 24 based on the time information of the remote control clock unit 12 included in the signal.

For example, the time of the lighting clock unit 24 of the lighting fixture 20 is 12:00, the time of the remote clock unit 12 of the remote control 10 is 17:13, and the automatic control activation information and the time of 17:13 are transmitted from the remote control 10. When a signal including information is transmitted, the time of the lighting clock unit 24 is corrected to 17:13 in the lighting fixture 20.

Then, when the time information of the lighting fixture 20 is corrected, the control unit 23 automatically controls the lighting of the lighting unit 22 based on the corrected time of the lighting clock unit 24 and the stored lighting conditions. When the control unit 23 stores the lighting condition of "relaxing hue" at the corrected time (for example, 17:13), the lighting condition of the lighting unit 22 is automatically changed to "relaxing hue". It is changed to and the lighting is controlled. Then, the lighting of the lighting unit 22 is controlled so as to be lit according to the time with the passage of time while the auto control is activated.

On the other hand, when the operator presses the comfort button 104 of the remote controller 10 again, the "comfort" display 101b on the display unit 101 is turned off, and the luminaire 20 is in a normal lighting state irrelevant to the time of day.

(Modification example)
In the signal transmitted from the transmission unit 11 of the remote control 10, the time information in the actual time unit of the remote control clock unit 12 is exemplified as the time information of the remote control clock unit 12 included in the signal, but the time information is not limited thereto. For example, the modified time information obtained by modifying the actual time unit time information into a predetermined time unit may be used. The time unit is, for example, hours, minutes, seconds, and the like. When the time displayed on the display unit 101 of the remote controller 10 advances every minute, for example, 17:11, 17:12, the actual time unit is one minute. On the other hand, modifying to a predetermined time unit means, for example, modifying the time represented by the actual time unit of 1 minute into a predetermined time unit (for example, 10 minutes of the time unit).

As a specific example, for example, in the case of the remote controller 10 shown in FIG. 2, the remote controller clock unit 12 has an actual time unit of 1 minute and an actual time unit of time information of 17:13. On the other hand, when the predetermined time unit is set to 10 minutes, the time information included in the signal transmitted from the transmission unit 11 of the remote controller 10 is 10 by rounding down the numerical value in the 1 minute range from the actual 17:13. The modification time information is modified in minutes at 17:10. When the time information expressed in the actual time unit is transmitted as a signal with the actual time unit as 1 minute, 60 minutes × 24 hours = 1440 data codes are required. On the other hand, when the predetermined time unit is set to 10 minutes, the data code can be compressed to 1/10 of the 1 minute unit. That is, with the modified time information set in a larger predetermined time unit (time length n, positive number, n> m) as compared with the actual time unit (time length m, positive number). By doing so, the data length can be made shorter than the time information in the actual time unit. The predetermined time unit (n) in modifying the time information is not limited to 10 minutes. For example, in the above example, when the predetermined time unit (n) is set to 60 minutes, the actual numerical value of 17:13 to 13 minutes is rounded down, and the modification time information is modified to 60 minutes as 17:00. May be good.

The predetermined time unit (n) is not particularly limited, and can be appropriately set according to a desired data length, for example. The predetermined time unit (n) is, for example, in the range of 2 minutes to 480 minutes, 2 minutes to 60 minutes, and 10 minutes to 60 minutes.

The signal transmitted from the remote controller 10 may have the same data length as the signal including the auto control activation information of the lighting fixture 20 and the time information and the signal not including the auto control activation information of the lighting fixture 20. preferable. The latter signal that does not include the activation information of the auto control is, for example, a general signal that does not include the activation information of the auto control of the lighting fixture 20 such as "all lights" and "turns off". If the data lengths of the former and the latter general signals are the same, for example, the reception accuracy on the luminaire 20 side is the same regardless of the type of signal. Therefore, for example, when the remote controller 10 is operated at a location far away from the lighting fixture 20, problems such as no signal being received can be sufficiently suppressed. Further, in the receiving unit 21 of the lighting fixture 20, for example, the threshold value for preventing noise detection is generally raised or lowered by a time constant, but if the data length is the same regardless of the signal type, the threshold value is generally raised or lowered by a time constant. False detection of noise when the threshold value is lowered can be sufficiently suppressed. In the present invention, the data length of the signal including the automatic control activation information of the lighting fixture 20 and the time information is, for example, the data length of the signal by modifying the time information in a predetermined time unit as described above. Can be easily set to be the same as the data length of a general signal that does not include the above-mentioned auto control activation information.

Then, when the time information of the lighting fixture 20 is corrected, the control unit 23 automatically controls the lighting of the lighting unit 22 based on the corrected time of the lighting clock unit 24 and the stored lighting conditions. When the control unit 23 stores the lighting condition of "relaxing color" at the corrected time (for example, 17:10 which is the modified time information), the lighting condition of the lighting unit 22 is "relaxed". It is automatically changed to "hue" and lighting is controlled. Then, the lighting of the lighting unit 22 is controlled so as to be lit according to the time with the passage of time while the auto control is activated.

[Embodiment 2]
FIG. 3 is a block diagram showing another example of the configuration of the lighting system of the present invention. As shown in FIG. 3, the lighting system of this example is the same as the lighting system of the first embodiment shown in FIG. 1, except that the remote controller 10 further includes the signal transmission assisting unit 13. As shown in the modification of the first embodiment, the lighting system of the present embodiment is suitable for the case where the signal includes the modification time information modified in the predetermined time unit.

The signal transmission assisting unit 13 has a time lag between the modified time information modified to the predetermined time unit included in the signal transmitted by the transmission unit 11 and the time information in the actual time unit, and the predetermined time. The time of the difference between the unit and the time of the deviation is calculated, and the time information of the actual time unit in the time after the time of the difference elapses from the time when the transmission unit 11 transmits the signal including the modification time information. The signal of the modified time information modified in the predetermined time unit is transmitted to the receiving unit 21 of the lighting equipment 20 via the transmitting unit 11.

As shown in the modification of the first embodiment, when the signal includes the modified time information modified to the predetermined time unit, the time information of the lighting clock unit 24 of the lighting fixture 20 is set to the predetermined time unit. It is corrected to the modified modification time information. In this case, when the time information of the actual time unit (for example, 17:10) is modified to the predetermined time unit (for example, 10 minutes), if the modified time information becomes the same as the actual time information, the illumination The time information of the lighting clock unit 24 of the appliance 20 is corrected to the same time (17:10) as the actual time information (17:10) of the remote clock unit 12 of the remote control 10. However, when the time information in the actual time unit (for example, 17:13) is modified to the predetermined time unit (for example, 10 minutes), the modified time information is different from the actual time information (17:13). In the case of information (17:10), the time information of the lighting clock unit 24 of the lighting fixture 20 is the actual time information (17:13) of the remote clock unit 12 of the remote control 10 within the range of the predetermined time unit. It is corrected to the time information (17:10) that is different from the above. According to the lighting system of the present embodiment, as shown below, even if the signal includes the modification time information and the actual time information and the modification time information deviate from each other, the deviation is further increased. After correction, the time information of the lighting clock unit 24 of the lighting fixture 20 can be used as the actual time information.

That is, according to the signal transmission assisting unit 13, the modified time information (for example, 17:10) modified into the predetermined time unit (for example, 10 minutes) included in the signal transmitted by the transmitting unit 11 and the actual actual time information. The time difference (3 minutes) from the time information in the time unit (for example, 17:13) and the time difference (7 minutes) between the predetermined time unit (10 minutes) and the time difference (3 minutes). ) Is calculated. Then, the signal transmission assisting unit 13 is an actual time unit at the time after the difference time (7 minutes) has elapsed from the time when the transmission unit 11 transmits the signal including the modification time information (17:13). The signal of the modified time information (17:20) obtained by modifying the time information (17:20) into the predetermined time unit (10 minutes) is transmitted to the receiving unit 21 of the lighting fixture 20 via the transmitting unit 11. The modified time information included in this signal is modified time information (17:20) that does not deviate from the actual time unit time information (17:20). Therefore, in the lighting fixture 20, when the receiving unit 21 receives the signal, the correction unit 25 deviates the time of the lighting clock unit 24 from the time information in the actual time unit based on the signal. Correct to a non-existent time.

Although the present invention has been described above with reference to the embodiments, the present invention is not limited to the above embodiments. Various changes that can be understood by those skilled in the art can be made to the structure and details of the present invention within the scope of the present invention.

According to the present invention, it is possible to provide a lighting system that can automatically change the lighting conditions of a lighting fixture according to the time of day. The lighting system of the present invention can be used in a wide range of applications such as home use and facility use.
