And The illumination load unit 1 is configured by an incandescent light bulb, a fluorescent lamp, or the like, and can perform predetermined dimming lighting by a control signal from the lighting control unit 6. The human sensor 2 detects the presence or absence of a human body, and may be of a pyroelectric type or an ultrasonic type. The illuminance sensor unit 3 is composed of, for example, CdS or a photodiode, and determines the light / dark state by measuring the illuminance around the illumination load unit 1 and comparing it with a reference illuminance level. The timer unit 4 counts a preset time, and includes, for example, a day mode (6:00 to 17:00), a night mode (17:00 to 23:00), and a midnight mode (23:00 to 6).
), And the lighting time of the lighting load unit 1 is measured. The setting unit 5 performs various settings for each unit, and sets a time zone of each mode, sets a light / dark determination value, sets a lighting state of the illumination load unit 1, and the like. Lighting control unit 6
Controls each unit, and may be configured by a microcomputer, or may be a general gate IC, a comparator, or a timer IC.

The unit 8 is a general mode return setting unit, and is a switch for switching an operation mode to a general mode (a mode of turning on 100% when a person comes and turning off the light when there is no person). By pressing
The switching to the general mode is determined by the lighting control unit 6, and the switching is performed.

Next, the operation of this embodiment will be described. First, the setting unit 5 sets a start time and an end time of a plurality of special modes in advance. For example, PM 6:00 to PM 10:00 is set as the “greeting mode”, and AM 1:00 to AM 5:00 is set as the “late night mode”. Thereafter, the lighting control unit 6 determines based on each information from the motion sensor unit 2, the illuminance sensor unit 3, and the timer unit 4, lights and dims the lighting load unit 1, and sets an appropriate lighting state according to the environment. To control.

The specific operation will be described with reference to the time chart of FIG. While the surroundings are bright, the illuminance sensor unit 3 does not operate, and the illumination load unit 1 does not turn on regardless of the presence or absence of a person.
Next, when the surroundings become dark, when a person comes, the lighting load unit 1 is turned on. And the time is PM6: 00 to PM10: 0
During 0, it is in "greeting mode"
% Dimming lighting is performed, and when a person comes, it becomes 100% lighting.
After 10:00 PM, it will only be 10 when people come.
The operation in the general mode is such that the light is turned on at 0% and turned off when no one is present. Next, AM1: 00 to AM5: 0
At "0", the mode becomes "midnight mode". When a person arrives, dimming lighting of 30% is performed and when there is no person, the light is turned off. The above operation is repeated every day, and optimal lighting control is performed according to the environment.

Here, for example, family members return home early on weekends or the like, and have a different behavior pattern from weekdays. In particular, the time in the “greeting mode” may be shortened. Then, after returning home, when the lighting is unnecessary, the general mode return SW unit 8 is pressed to temporarily change the “greeting mode” (for example, only during the “greeting mode”) to the general mode (where a person can come). For example, it returns to a mode in which the lamp is turned on 100% and turned off when not. However, since only the initially set timer for one day is operating, the next day, the operation as originally set is started again.

According to the present embodiment, the "greeting mode"
And the general mode return switch section 8 for temporarily returning to the general mode from the special mode called “midnight mode” increases the degree of freedom of operation, and can turn off the light, especially when lighting is unnecessary, and saves energy. is there. In addition, the operation mode automatically returns to the state of the predetermined setting on the next day, so that there is no need to reset the setting.

FIG. 3 is a block diagram showing a schematic configuration of a lighting device according to a second embodiment of the present invention. This embodiment is different from the above-described embodiment in that the power supply is turned off instead of the general mode return SW section 8 as the general mode return setting means.
A time detecting unit 9 is provided. The power-off time detecting section 9 measures the off-time of the power supply 7, and the lighting control section 6 determines whether to return to the general mode based on the measured length of the off-time. That is, as shown in FIG. 4, when the off time is a short time such as t1, the mode returns to the general mode, and when the off time is a long time such as t2, the operation mode is not changed.

In the case of this embodiment, the normal mode return S
It is possible to temporarily return to the general mode without providing a special switch such as the W unit 8.

FIG. 5 is a block diagram showing a schematic configuration of a lighting device according to a third embodiment of the present invention. This embodiment is different from the first embodiment in that a time adjustment unit 10 is provided as a general mode return setting unit instead of the general mode return SW unit 8. The time adjustment unit 10 includes the timer unit 4
When the switch (knob) is turned off once and returned again, the mode is shifted from the special mode to the general mode. Other operations are the same as those of the first embodiment.

FIG. 6 is a block diagram showing a schematic configuration of a lighting device according to a fourth embodiment of the present invention. This embodiment is different from the first embodiment in that a temporary lighting S is used instead of the general mode return SW unit 8 as a general mode return setting unit.

This is a switch for temporarily turning on the lighting load unit 1 all the time. By operating this switch, the mode shifts from the special mode to the general mode.

The basic operation of this embodiment is the same as that of the first embodiment. However, as shown in FIG. 7, for example, when operating in the "late night mode" and getting up early in the morning, sufficient brightness is obtained. There is a situation in which you want 100% lighting. At this time, when the temporary lighting SW unit 11 is pressed, the normal mode is temporarily changed from the “late night mode” (100
% Lighting mode, and turn off when it is not). This mode automatically returns to the "late night mode" after a predetermined time has elapsed.
Therefore, in the present embodiment, it is possible to change to the general mode for a predetermined time after the operation of the temporary lighting SW unit 11.

FIG. 8 is a block diagram showing a schematic configuration of a lighting device according to a fifth embodiment of the present invention. The present embodiment has a configuration in which a human sensor unit 12 and a sensor detection number processing unit 13 are provided as the general mode return setting unit in place of the general mode return SW unit 8 in the first embodiment. The human sensor unit 12 detects a person only in the area of the entrance door, and the sensor detection number processing unit 13 counts the number of detections by the human sensor unit 12 and sets a certain value (for example, in a family of four). When the value reaches 4), the information is output to the lighting control unit 6. The lighting control unit 6 changes from the “greeting mode” to the general mode based on the output from the sensor detection number processing unit 13.

In this embodiment, as shown in FIG. 9, during the operation in the "greeting mode", when the number of detections by the human sensor unit 12 reaches four, an output is made from the sensor detection number processing unit 13, The mode is changed to the general mode (a mode in which the light is turned on 100% when a person comes and is turned off when there is no person). In other words, if the number of family members enters the entrance, it is no longer necessary to set the "greeting mode", so by switching to the general mode at that point, 50% dimming lighting even when there are no people It is possible to prevent useless lighting due to.

FIG. 10 is a block diagram showing a schematic configuration of a lighting device according to a sixth embodiment of the present invention. This embodiment is obtained by adding a time storage processing unit 14 to the first embodiment. The time storage processing unit 14 stores the time when the switch of the general mode return SW unit 8 is pressed for a predetermined period (for example, one week), and obtains, for example, an average time. The lighting control unit 6 changes the end time of the “greeting mode” based on the information on the average time from the time storage processing unit 14. That is, the time when the switch of the general mode return SW unit 8 is pressed for one week is, for example, 9:00, 8:30, 9:30, 8:00,
If it is 9:00, 10:00, and 8:30, the information that the average time is 9:00 is stored in the time storage processing unit 14.
Is sent to the lighting control unit 6 and the “Welcome mode” of the next week

Calendar setting unit 15
Also has the function of the setting unit 5. The calendar setting unit 15 sets the start time and end time of a plurality of special modes. The setting can be made separately for weekdays and holidays. For example, as shown in FIG. 12A, on weekdays, PM 6: 0 is set as the “greeting mode”.
0-1PM 10:00, as "midnight mode", AM1:
00-AM 5:00 is set, and as shown in FIG.
~ PM 8:00, "Midnight mode", AM 1:00
~ AM 5:00 is set. Therefore, the end time of the “greeting mode” of the holiday is set earlier, and PM 8:00 to operate in the “greeting mode” on weekdays
Since PM 10:00 is in the general mode, even if a family member goes out on a holiday, the time to return home is relatively earlier than on weekdays, so that unnecessary lighting can be eliminated accordingly.

According to the present embodiment, the calendar setting unit 1
According to 5, since the time setting of the operation mode on weekdays and holidays can be distinguished, the degree of freedom of operation is large, and fine control can be performed, which further saves energy. Also, once the time setting of the operation mode on weekdays and holidays is performed once, the operation automatically repeats, so there is no need to redo the setting. In the present embodiment, the case of two settings of weekdays and holidays has been described. However, finer settings may be made.
