[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device,
More specifically, the present invention relates to a lighting device capable of changing and switching a load state by an OFF / ON operation.

[0002]

2. Description of the Related Art As a conventional illuminating device, as shown in FIG. 9, an illuminance detecting means 11 for detecting ambient brightness, a human body detecting means 12 for detecting the presence of a human body, and the detecting means 11 and 12 are provided. DC voltage from the commercial power supply 30, a control unit 13 that receives a signal and outputs a lighting control signal for the lighting load 17, a lighting circuit unit 14 that receives a control signal output from the control unit 13, and controls lighting of the lighting load 17. The power supply circuit unit 15 for generating a power failure, the power failure detection circuit unit 16 for detecting a power failure, and the illumination load (light source) 17 were provided.

The operation of this lighting device will be briefly described below.
When the ambient illuminance detected by the illuminance detecting means 11 becomes equal to or lower than a preset predetermined illuminance, the control unit 13 outputs a control signal to the lighting circuit unit 14, and the lighting circuit unit 14 performs dimming control of the lighting load 17. . When the illuminance detected by the illuminance detecting means 11 is equal to or lower than the predetermined illuminance, and when the human body detecting means 12 detects a human body, the control unit 13 controls the lighting load 17 to be fully turned on (100% lighting), and after the human body detection is completed. Is controlled to hold the full lighting state for the lighting holding time. Further, when the illuminance detected by the illuminance detecting means 11 becomes higher than the predetermined illuminance, the control unit 13 controls the lighting load 17 to be turned off. Hereinafter, the control operation will be referred to as a sensor mode.

When the switch 20 is turned off in the sensor mode, the power failure detection circuit section 16 outputs a signal to the control section 13, and the control section 13 again switches the switch 2
The time until 0 is turned ON is within a predetermined time (for example, 0.2
Second to 2 seconds). Switch 20
If the OFF time is within a predetermined time, the illuminance detection means 11
Irrespective of the output from the human body detection means 12, the control unit 13 forcibly shifts to the control operation of continuously lighting (full lighting) the lighting load 17. Hereinafter, the control operation will be referred to as a continuous mode.

The lighting device main body 10 thus configured
Since it is possible to easily switch the mode from the sensor mode to the continuous mode by operating a switch such as a wall switch, it is not necessary to separately provide a switch means for mode switching in the lighting device, which not only costs less. Even if the lighting equipment is installed at a high place such as the ceiling of the entrance, the mode can be easily switched.

[0006]

However, in such an illuminating device, the sensor mode can be switched to the continuous mode by a simple switch operation, but the switch is not necessarily performed only by the operation intended by the user. It was a thing. For example, there is a problem that the mode shifts due to a momentary power failure such as a lightning strike, and the lighting load continues to be continuously lit, resulting in being left unattended and wasting power. Moreover, even if the user mistakenly operates the switch, the same trouble occurs.

In order to solve this problem, the control unit 13
A timer unit 19 (not shown) is provided inside the device, the timer unit is operated at the time of shifting to the continuous mode, and the continuous mode is continued when the timer unit is in operation, but when a predetermined time elapses, the control unit There was also a lighting device 13 that automatically returns from the continuous mode to the sensor mode.

However, even in such an illuminating device, the problem that the power is wasted as long as the timer section is operating cannot be solved, and the illuminating load is detected by the human body detection or the illuminance detection signal. Since it is a lighting device that controls lighting, for users who do not intentionally provide a switch means such as a wall switch, the function to transition to the continuous mode may not be necessary, and the problem still remains. It was a thing.

The present invention has been made in view of the above-described facts, and its purpose is to prevent power from being wasted, and to provide a user with a function depending on the convenience and the situation. An object is to provide a lighting device that can be freely selected.

The embodiments of the present invention will be individually described below.

(Embodiment 1) FIG. 1 is a block diagram showing a configuration of an illumination device according to a first embodiment of the present invention.

The difference from the above-mentioned conventional lighting device is that it has a changeover switch 18 for selecting whether the mode shifting operation is valid or invalid, as shown in FIG. The operation will be briefly described below.

When the changeover switch 18 is ON, the control unit 1
3 determines that the mode transition operation is valid, and when the switch 20 is turned off in the above-mentioned sensor mode, the power failure detection circuit unit 16 outputs a signal to the control unit 13, and the control unit 13 turns on the switch 20 again. It is determined whether or not the time until it falls within a predetermined time. If the OFF time of the switch 20 is within a predetermined time (for example, 0.2 seconds to 2 seconds), the control unit 13 forcibly keeps the illumination load 17 continuous regardless of the outputs of the illuminance detection means 11 and the human body detection means 12. It shifts to the continuous mode of lighting (full lighting). Reverse switch 1
When 8 is OFF, the control unit 13 determines that the mode shift operation is invalid, and does not shift to the continuous mode even if there is a switch operation for mode shift in the above-mentioned sensor mode, and continues the sensor mode.

In the lighting device controlled as described above, the control unit 13 detects the state of the changeover switch 18,
In the case of N, the sensor mode is switched to the continuous mode by operating the mode switching switch, but in the case of OFF, the sensor mode is continued even if the mode switching switch is operated. There is an effect that the function can be selected. That is, the changeover switch 1
When 8 is turned off, there is no momentary power failure or transition to continuous mode even if the user mistakenly operates the switch, and it is possible to eliminate the problem that power is wasted by leaving the dots on. The usability is improved for the user who dares to use a switch means such as a wall switch. Also, turn on the changeover switch 18.
Even in such a case, similarly to the conventional case, the mode can be easily switched from the sensor mode to the continuous mode by operating a switch such as a wall switch, and the conventional usability is not impaired.

(Embodiment 2) FIG. 2 is a block diagram showing a configuration of an illumination device according to a second embodiment of the present invention.

The difference from the first embodiment is that the switching means 18 is not a switch but a variable resistor, and a timer section 19 is provided inside the control section 13.
3 and 4 show the setting unit of the switching means 18 of this embodiment.

As shown in FIG. 3, the concave portion of the switching means 18 is "cut".
In the position of, the control unit 13 detects the setting of the switching unit 18 and determines that the mode shifting operation is invalid. In the sensor mode described above, even if a switch operation for mode transition is performed, the sensor mode is continued without transitioning to the continuous mode. On the contrary, when the concave portion of the switching means 18 is at a position other than "off" as shown in FIG.
8 setting is detected, and the mode shift operation is determined to be valid.
In the above sensor mode, when the switch 20 is turned off, the power failure detection circuit unit 16 outputs a signal to the control unit 13, and the control unit 13 turns on the switch 20 again within a predetermined time (for example, 0). . 2 seconds to 2 seconds). If the OFF time of the switch 20 is within the predetermined time, the control unit 13 forcibly shifts the lighting load 17 continuously (full lighting) regardless of the outputs of the illuminance detection unit 11 and the human body detection unit 12. To do. Here, at the time of shifting to the continuous mode, the timer unit 19 in the control unit 13 operates the timer of a predetermined time set by the switching unit 18 (4 hours in the present embodiment), and when the timer is operating, it continues. Although the mode continues, the control unit 13 automatically returns from the continuous mode to the sensor mode when a predetermined time elapses. Further, when the concave portion of the switching means 18 is set to the “continuous” position (not shown), the sensor mode is switched to the continuous mode by the above-described mode switching switch operation, but the control section 13 does not operate the timer section 19. , To continue the continuous mode.

In the lighting device controlled as described above, in addition to the effect similar to that of the first embodiment, the time control after the mode transition can be set, so that the usability is further improved. It is a thing.

In the present embodiment, the switching means 18 is composed of a variable resistor, but it is not limited to this, and needless to say, it may be a switching means such as a slide switch or the like. 2H, 4H, 6H
It does not have to be limited to.

(Embodiment 3) FIG. 5 is a block diagram showing a configuration of a reference example of an illumination device according to a third embodiment of the present invention. Then, FIG. 6 is a timing chart showing the control operation of the reference example of the lighting device according to the third embodiment of the present invention.

First, the difference from the above-mentioned conventional example is that the switch 20 is provided with a firefly switch. When the switch unit 21 is OFF, the neon tube 22 and the current reducing resistor 23
Although the neon tube 22 is turned on by a weak current flowing through the series circuit of No. 2, when the switch unit 21 is ON, power is supplied to the lighting device main body 10 without going through the above series circuit. That is, since the neon tube 22 inside the switch is turned on when the switch unit 21 is turned off, even if the lighting load 17 in the lighting device body 10 installed in a dark place such as a corridor or stairs is turned off, This is so that the position of the switch 20 can be seen.

Here, in the above-mentioned sensor mode, when the switch unit 21 is turned off (point c in FIG. 6), the power failure detection circuit unit 16 outputs a signal to the control unit 13, and the control unit 13
Determines again whether the time T until the switch 21 is turned on is within a predetermined time (for example, 0.2 seconds to 2 seconds) (points c to d in FIG. 6). OFF time T of switch 21
Is within a predetermined time, the control unit 13 forcibly shifts to the continuous mode in which the lighting load 17 is continuously lit (full lighting) regardless of the outputs of the illuminance detection unit 11 and the human body detection unit 12. When a momentary power failure such as a lightning strike occurs and the A contact of FIG. 6 is turned off (point a in FIG. 6), the power failure detection circuit unit 16
Similarly outputs a signal to the control unit 13, and if the time t until the A contact is turned on (power recovery) again is within a predetermined time (for example, 0.2 seconds to 2 seconds), This leads to a transition to a continuous mode of continuous lighting (full lighting).

FIG. 7 is a block diagram showing the structure of an illumination device according to the third embodiment of the present invention. And FIG.
[Fig. 6] is a timing chart showing a control operation of an illumination device according to a third embodiment of the present invention. The difference from the reference example of FIG. 5 is that a transformer 18 for current detection is provided in the lighting device main body 10 and the output of the secondary winding is used for the power failure detection circuit 16
I was connected to. To explain the operation, in the sensor mode described above, when the switch 21 is turned off (point c in FIG. 8), the neon tube 22 and the current-reducing resistor 23 inside the switch 20, and the primary winding of the transformer 18 inside the lighting device body 10. A weak current flows through the series circuit of, and a voltage is induced on the secondary side of the transformer 18. Next, the power failure detection circuit 16 detects the voltage on the secondary side and outputs a signal to the control unit 13 if the voltage is within a predetermined threshold range, and the control unit 13 waits until the switch 21 is turned on again. Time T, that is, the output time of the power failure detection circuit 16 is within a predetermined time (for example, 0.2 seconds to 2
Second)) (points c to d in FIG. 8). If the time T is within the predetermined time, the control unit 13 forcibly shifts to the continuous mode in which the lighting load 17 is continuously lit (full lighting) regardless of the outputs of the illuminance detection unit 11 and the human body detection unit 12. is there. Here, when a momentary power failure such as a lightning strike occurs and the A contact of FIG. 7 is turned off, power is not supplied to the switch 20 and the lighting device main body 10, so that the secondary voltage of the transformer 18 is not induced and the power failure occurs. Detection circuit 16
Is also turned off (points a to b in FIG. 8). Control unit 13
Since there is no output signal from the power failure detection circuit 16, the sensor mode is continued.

In the lighting device controlled as described above, the condition that the power failure detection circuit 16 detects the secondary side voltage of the transformer 18 and is within a predetermined threshold range, that is, the firefly current is detected. To the control unit 13,
Since the control unit 13 shifts from the sensor mode to the continuous mode, it is possible to eliminate the problem that the mode shifts unintentionally due to a change in the power supply environment such as an instantaneous power failure, and the power is wasted by keeping on. It has the effect of eliminating problems.

In this embodiment, the transformer is used as the means for detecting the firefly current, but the present invention is not limited to this, and it is needless to say that substantially the same effect can be obtained by detecting by other means.

[0042]

According to the lighting apparatus of the present invention having the above-described structure, since the switching device for selecting whether the mode transition operation is valid or invalid is provided, the user can change the function depending on the usability and the situation. There is an effect that can be selected.
In other words, when the transition operation is disabled, there is no momentary power failure or transition to continuous mode even if the user mistakenly operates the switch, and the problem of wasting power due to turning on and off can be eliminated. In particular, the usability is improved especially for the user who does not intentionally provide a switch means such as a wall switch. Also,
Even when the transition operation is made effective, the mode can be easily switched from the sensor mode to the continuous mode by operating a switch such as a wall switch as in the conventional case, and the conventional usability is not impaired.

Further, since the control section is provided with a means for detecting a firefly current and switches from the sensor mode to the continuous mode on the condition that the current is detected, the mode is unintentionally changed due to an instantaneous power failure such as a lightning strike or a change in the power supply environment. Can be eliminated, and there is an effect of eliminating the problem that power is wasted by keeping on.

It should be noted that, as in the present invention, if switching means for selecting valid or invalid is provided, or means for detecting a firefly current is provided and the switching of the load state is made effective on the condition of detection. Not limited to the configuration of the embodiment of the present invention, in a lighting device that can switch the load state to, for example, full lighting (100% lighting), dimming lighting, bean ball lighting, and lighting extinction by turning the wall switch off and on. Also,
It goes without saying that the same effect as the present invention can be obtained. The same effect can be obtained when the lighting device is a remote control type.
