Description

The present invention relates to luminaires and luminaires that are connected to an AC power source via a phase control dimmer that controls the phase of the switch and the AC power source and are dimmed by the phase control dimmer, especially for users. The present invention relates to a lighting fixture and a lighting system that detects that a pullless operation, which is an operation of turning the switch on and off again within a certain period of time, is performed to control toning and the like.

A lighting fixture that changes the color of lighting by detecting that a user has operated a switch pulllessly while a phase control type dimmer that adjusts the brightness of a light source is connected is described in, for example, Patent Document 1. It is known as disclosed.

Japanese Patent No. 6113669

However, in recent years, general-purpose phase control type dimmers are becoming more multifunctional so as to be compatible with remote control operation or anti-phase control. As a result, an output stop period of 100 msec or more has elapsed since the switch was turned on, in order to secure the control power supply in the dimmer or to complicate the operation of the microcomputer in the dimmer due to higher functionality. After that, the output of the dimmer may be sent out.

In this case, the pullless operation should be detected in a predetermined off time, but it will be detected including the output stop period of 100 mec or more. Moreover, the above-mentioned output stop period is not constant for each dimmer manufacturer, for each type of dimmer, or due to variations in parts and the like. Detecting a pullless operation in such a state and controlling the function of the luminaire such as changing the color of the luminaire causes various problems.

One of them is that even if the pullless operation time is the same, the detection time is different for each dimmer, so the required pullless operation time varies, so the dimmer is limited to ensure operability, or more than necessary. In addition, there is a problem that the capacity of the capacitor is increased in order to maintain the holding time, and as a result, the lighting equipment is also increased.

As another problem, it is known that momentary voltage reduction frequently occurs during normal use, and usually, it is configured so that there is no problem in voltage reduction of about 100 msec or less. However, in this case, if the output of the dimmer is sent after the output stop period of 100 msec or more has elapsed since the switch was turned on, and if voltage reduction measures of 100 msec or less are taken, the pullless operation detection time of 200 msec or more is taken. Is required. When trying to have versatility, it is not possible to identify a voltage reduction of 100 msec or less, and it is judged that a pullless operation was performed under normal use conditions, and control such as color change is performed. There is.

As another problem, in order to correct the color shift of each luminaire when multiple luminaires are connected to the dimmer, the operation of resetting the color by several pullless operations is frequently used. .. In this case, the detection time of the pullless operation is not direct, so the risk of failure increases. As a result, it may take time to correct the color shift or it may not be possible at worst.

These problems are just an example, and it is thought that there are various other problems. If the output of the dimmer is sent within 100 msec or less after the switch is turned on, a certain measure can be taken regarding the instantaneous voltage reduction, and the difference between the pullless operation time and the detection time is limited. It is considered that the above-mentioned problems are few.

According to the inventions described in the preceding paragraphs (1), (10), (11) and (20), the output of the phase control type dimmer is stopped and then restarted by the first detection means of the luminaire. It is detected that the output stop period of the phase control type dimmer exists after the output is restarted by the second detection means, and the phase control type adjustment is detected by the third detection means. When the continuous supply of the output after the output stop period of the dimmer is detected, the determination means determines whether or not the pullless operation has been performed. Therefore, for example, 100 msec or more after the output of the dimmer is switched on.

It is a timing chart for explaining the operation of a luminaire. It is a flowchart which shows the determination process of a pullless operation. It is a continuation of the flowchart of FIG. It is a figure which shows the modification of the phase control type dimmer.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of a lighting system 1 according to an embodiment of the present invention. In this lighting system 1, a plurality of lighting fixtures 10 simultaneously turn on or off all the lighting fixtures 10, and a phase control type dimmer (1 phase control type dimmer) in which all the lighting fixtures 10 are dimmed at the same time. Hereinafter, it is connected in parallel to the commercial AC power supply 2 via the dimmer (4).

The dimmer 4 controls the phase of the AC power supply 2 based on the operation of the adjustment knob (volume) by the user to control the supply and cutoff of the input power from the AC power supply 2 to each luminaire 10. The brightness of the light source 16 in each luminaire 1 is adjusted. As shown in FIG. 2, the switch 3 and an operation volume 41 for adjusting the degree of dimming are integrally provided in the switch unit 5, and the switch unit 5 is attached to a wall surface or the like in the room. ..

Further, in this embodiment, the dimmer 4 is a high-performance dimmer, and when the switch 3 is turned on, the dimmer 4 supplies a short output, and then continuously after an output stop period of 100 msec or more. It has the characteristic of supplying a typical output.

The configuration of the luminaire 10 is shown in the circuit diagram of FIG. In this embodiment, the luminaire 10 uses a downlight as the luminaire 10, but the luminaire 10 is not limited to the downlight.

FIG. 3 is a circuit diagram showing the configuration of the lighting fixture 10. Each luminaire 10 has the same configuration.

The luminaire 10 includes a rectifier circuit 11, an input circuit 12, an AC-DC conversion circuit 13, a control unit 14, a drive unit 15, a light source 16, and the like.

The rectifier circuit 11 is a circuit connected to terminals P1 and P2 on the AC power supply 2 side to perform full-wave rectification of the AC input from the AC power supply 2 (dimmer 4), and the input circuit 12 is rectified by the rectifier circuit 11. The voltage value is lowered by dividing the subsequent input voltage. In this embodiment, the input circuit 12 divides the input voltage by the resistors R1 and R2.

As shown in FIG. 4, the input circuit 12 has a configuration in which one end of the resistor R1 is connected to the cathodes of the diodes 17 and 18 to which the anodes are connected to the terminals P1 and P2 on the AC power supply 2 side, respectively. Is also good. The circuit of FIG. 4 is the same as the circuit diagram of FIG. 3 except for the configuration of the input circuit 12.

The AC-DC conversion circuit 13 eliminates the pulsating current of the input voltage after full-wave rectification by the rectifier circuit 11 to generate a stable DC power supply. The DC power source generated by the AC-DC conversion circuit 13 is used as a drive power source for the light source 16 and a power source for the control unit 14.

The control unit 14 includes a CPU 141, a ROM 142, and a RAM 143, and controls the overall operation of the lighting fixture 10. In particular, in this embodiment, the presence or absence of a pullless operation of the switch 3 performed by the user is determined and determined by monitoring a voltage (hereinafter referred to as a monitoring voltage) whose voltage is divided by the input circuit 12 and whose voltage value is reduced. It has a function to control toning and the like based on the result. The specific determination method of the pullless operation will be described later.

The ROM 142 stores an operation program of the CPU 141, various setting values for determining whether or not it is a pullless operation, and the CPU 141 performs a predetermined operation according to these operation programs and the setting values. The RAM 143 provides a working area when the CPU 141 operates.

The drive unit 15 drives the light source 16 to light up, and adjusts the color temperature of the light source 16, that is, adjusts the color, based on the instruction of the control unit 14 according to the detection result of the pullless operation.

As the light source 16, a light source made of a light emitting diode (LED) is preferably used, but the light source 16 is not limited thereto. Further, in this embodiment, a light source for a downlight is used as the light source 16, but any light source can be used. Further, as an example of toning the light source 16, in this embodiment, the color temperature of neutral white and the color temperature of the light bulb are alternately switched each time the pullless operation is performed, but the method of toning is limited to this. There may be a configuration in which the color temperature is switched to three or more types.

Next, the operation of the lighting fixture 10 shown in FIG. 3 will be described with reference to the timing chart of FIG.

When the user turns on the switch 3 to turn on the lighting fixture, the AC voltage V1 is input from the AC power supply 2 as shown in FIG. 5A to the input of the dimmer 4.

The dimmer 4 repeats the operation of turning on at the phase corresponding to the dimming degree set by the volume 41 for operation in each half cycle of the AC voltage V1 and turning off at the end of each half cycle, and dimming. As shown in FIG. 5B, the device 4 outputs a voltage V2 in which the front portion of each half cycle is cut off. The dimmer 4 may be of the antiphase type, which is turned on at the start of each half cycle of the AC voltage V1 and turned off at the phase corresponding to the dimming degree set by the volume 41 for operation. .. In this case, the dimmer 4 outputs a voltage in which the rear portion of each half cycle is cut off.

As a result of the rectifier circuit 11 full-wave rectifying the output voltage V2 of the dimmer 4, the voltage V5 shown in FIG. 5 (C) is output from the rectifier circuit 11.

Next, it is assumed that the user turns off the switch 3 at the timing T1 and turns it on at the timing T2 for the pullless operation. Since the output of the rectifier circuit 11 is turned off at the timing T1 and turned on at the timing T2, the monitoring voltage divided by the input circuit 12 becomes equal to or less than the reference voltage Vr at the timing T1 and exceeds the reference value at the timing T2. The control unit 14 detects when the monitoring voltage becomes equal to or less than the reference voltage Vr, starts the time measurement, ends the time measurement when the monitoring voltage exceeds the reference value, and starts the time measurement (timing T1). The time t1 from to the end (timing T2) is measured.

As described above, the dimmer 4 is a high-performance dimmer, and as shown in FIG. 5B, when the user turns on the switch 3 at the timing T2, the dimmer 4 has a short width, for example, 1. The output voltage V3 having a period or less is supplied. The short output voltage V3 supplied when the switch 3 is turned on is supplied with power via a noise prevention capacitor (not shown) connected between the input and output of the dimmer 4 at the moment the switch 3 is turned on. This is because it is supplied to the lighting fixture 10 side, or because the triac, which is a switch element in the dimmer, is self-turned depending on the type of the dimmer 4, and is known to those skilled in the art. After supplying the output voltage V3 with this short width, it has the characteristic of restarting the continuous supply of the output V4 at the timing T4 after the output stop period t2 set in advance by the dimmer 4, for example, 100 msec or more. There is.

According to the above operation of the dimmer 4, the output of the rectifier circuit 11 also has a short output voltage V6 corresponding to the short output voltage V3 of the dimmer 4, as shown in FIG. 5 (C). After the output, the output of the rectifier circuit 11 also becomes zero during the output stop period t2 of the dimmer 4, and the output voltage V7 obtained by full-wave rectifying the output voltage V4 of the dimmer 4 from the timing T4 at which the output stop period t2 ends. Is output.

However, when the output of the dimmer 4 is restarted at the timing T2 and the output is stopped in the output stop period t2 after the short output voltage V3 is supplied, the output stop period is due to the recent improvement in the functionality of the dimmer 4. When t2 becomes 100 msec or more, various problems occur. One is that the pullless operation is counted twice because the output stop period t2 of the dimmer 4 is long. Another problem is that the dimmer 4 is determined to be a pullless operation during the output stop period t2 and is attempted to be controlled, but it is a problem that occurs because power is not supplied to the luminaire 10 side. For example, when changing the color of the lighting by pullless operation, an instruction to change the color is issued after the operation time t1 is detected, and although the color has changed, since the output stop period t2 of the dimmer 14 is in effect, power is supplied to the lighting fixture 10 side. There is no supply and it goes out. After that, when the output stop period t2 of the dimmer 14 ends and the output is re-output, the light is emitted. In this case, the user will see an unpleasant blink. As another problem, when a firefly switch is used for the switch 3, when an unexpected noise is generated in the lighting fixture 10, it may be erroneously recognized that a pullless operation has been performed depending on the timing.

Therefore, in this embodiment, after the detection that the output stop period t2 exists, and after the detection of the continuous output from the dimmer 4, the presence / absence of the pullless operation is determined.

That is, the output voltage of the rectifier circuit 11 is divided by the input circuit 12, and is compared with the reference voltage Vr by the control unit 14 as a monitoring voltage. The monitoring voltage exceeds the reference voltage Vr at the timing T2 when the switch 3 is turned on and the short voltage V6 is output from the rectifier circuit 11, and becomes equal to or lower than the reference voltage Vr at the timing T3 when the voltage of the voltage V6 drops.

When the output voltage V3 having a short width of the dimmer 4 exists for half a cycle or more, the value of the output voltage V6 drops in the latter half of the first half wave of the output voltage V6 of the rectifier circuit 11, so that the reference voltage Vr The voltage becomes as follows, and the voltage of the voltage V6 immediately exceeds the reference voltage Vr in the first half of the subsequent half wave. However, in this embodiment, when the value of the output voltage V6 is shorter than the reference voltage Vr for a short time (for example, about 10 ms or less), the control unit 14 ignores this and the value of the output voltage V6 is the reference voltage. The setting is made to consider that the state exceeding Vr continues.

Therefore, as shown in FIG. 5D, the control unit 14 recognizes that the value of the output voltage V6 exceeds the reference voltage Vr from the timing T2 to the timing T3. Further, the control unit 14 measures the time t4 from the timing T2 to the timing T4 when the output stop period t2 of the dimmer 4 ends and the output resumes.

After the lapse of the timing T4, the rectifier circuit 11 outputs an output voltage V7 obtained by full-wave rectifying the output voltage V4 of the dimmer 4, and the value of this output voltage V7 is also compared with the reference voltage Vr. In this case, the output voltage V7 intermittently has an off period between each half wave corresponding to the off of the dimmer 4, so that the value of the output voltage V7 is equal to or less than the reference value Vr. Time t3 occurs intermittently.

However, the time t3 when the reference voltage is Vr or less is a short time, and as described above, if the time when the reference voltage is Vr or less is a short time (for example, about 10 ms or less), the control unit 14 ignores this and outputs. The setting is made to consider that the state in which the value of the voltage V7 exceeds the reference voltage Vr continues. Therefore, as shown in FIG. 5D, the control unit 14 recognizes that the value of the output voltage V7 exceeds the reference voltage Vr after the timing T4, and at the same time, the timing T4 for restarting the output of the dimmer 4 The duration t5 of the output from is measured.

In this way, the control unit 14 has a first time t1 from the timing T1 when the switch 3 is turned on to the timing T2 when the switch 3 is turned off, and a second time t4 from the timing T2 to the timing T4 when the output stop period t2 ends. , The third time t5, which is the continuous supply time of the output of the dimmer 4 from the timing T4, is measured.

Then, the control unit 14 detects that the output of the phase control type dimmer is stopped and then restarted at the first time t1, and the output of the dimmer 4 is restarted at the second time t4. When it is detected that the output stop period t2 exists and the continuous supply of the output after the output stop period t2 of the dimmer is detected by the third time t5, it is determined whether or not the pullless operation is performed. do.

Specifically, when the first time t1 is within the first threshold value, the control unit 14 may determine that the pullless operation has been performed. When the user performs a normal on / off operation of the switch 3 instead of a pullless operation, the first time t1 becomes long. Therefore, by setting the first threshold value, such an operation is determined to be a pullless operation. Can be prevented. As the first threshold value, for example, 100 to 200 msec is desirable.

Further, when the second time t4 is equal to or less than the second threshold value, it may be determined that the output stop period t2 exists after the output of the dimmer 4 is restarted. For example, 400 msec can be exemplified as the second threshold value. 400 msec is a time considering an appropriate time (generally within 500 msec) from the time when the switch 3 is turned on until the lighting equipment 10 is turned on.

Further, when the third time t5 is equal to or greater than the third threshold value, it may be determined that the output is continuously supplied after the output stop period t2. As a result, noise is generated during the output stop period t2, and it is possible to prevent erroneous determination of the pullless operation due to the determination that the noise is the output restart after the output stop period t2. For example, 30 msec can be exemplified as the third threshold value. If it is 30 msec, the continuous supply of the output of the dimmer 4 can be sufficiently confirmed, and the false judgment of the pullless operation due to noise can be surely prevented. It can be shortened.

In this way, by performing the pullless operation determination after the elapse of the output stop period t2 of the dimmer 4, the problem of counting the pullless operations twice and the problem of control being performed during the output stop period t2 of the dimmer 4. Will be resolved.

FIG. 6 is a flowchart showing a determination process of the pullless operation performed by the control unit 14. This process is executed by the CPU 141 of the control unit 14 operating according to the operation program stored in the ROM 142 or the like.

In step S01, the monitoring voltage of the input circuit 12 becomes equal to or less than the reference voltage Vr, and the measurement of the first time t1 is started. In step S02, it is determined whether or not the monitoring voltage becomes equal to or more than the reference voltage Vr. If the monitoring voltage does not exceed the reference voltage (NO in step S02), it stays in step S02 until it exceeds the reference voltage. When the monitoring voltage becomes equal to or higher than the reference voltage Vr (YES in step S02), the first time t1 is stored at the timing T2 in step S03.

Next, in step S04, it is determined whether or not the monitoring voltage is equal to or lower than the reference voltage. That is, the timing T3 in FIG. 5 is determined. If the monitoring voltage does not fall below the reference voltage (NO in step S04), it stays in step S04 until it falls below the reference voltage. When the monitoring voltage becomes the reference voltage Vr or less (YES in step S04), it is determined in step S05 whether the monitoring voltage becomes the reference voltage Vr or more. That is, the timing T4 in FIG. 5 is determined.

If the monitoring voltage does not exceed the reference voltage Vr (NO in step S05), the process remains in step S05 until the reference voltage becomes Vr or higher. When the monitoring voltage becomes equal to or higher than the reference voltage Vr (YES in step S05), the second time t4 is measured at the timing T4 in step S06.

Then, in step S07, it is checked whether or not the second time t4 is 400 ms or less. If it is not 400 ms or less (NO in step S07), the process returns to step S01. If it is 400 ms or less (YES in step S07), in step S08, it is checked whether the monitoring voltage is higher than the reference voltage Vr in the third period t5 (300 ms in this example). That is, it is checked whether or not the output from the dimmer 4 is continuous. If the monitoring voltage is not higher than the reference voltage Vr (NO in step S08), the process returns to step S01. If the monitoring voltage is higher than the reference voltage Vr (YES in step S08), the process proceeds to step S09.

In step S09, it is checked whether or not the first time t1 is within a predetermined time. If it is not within a predetermined time (NO in step S09), the operation that caused the first time t1 is not a pullless operation, so the process returns to step S01. If it is within a predetermined time (YES in step S09), it is determined in step S10 that the operation that caused the first time t1 is a pullless operation, and then the process proceeds to step S11 in FIG.

In step S11, in order to determine whether or not the pullless operation has been continuously performed, it is checked whether or not a predetermined predetermined time has elapsed. If the predetermined time has not elapsed (NO in step S11), it is determined in step S13 whether or not the monitoring voltage has become the reference voltage Vr or less. If the monitoring voltage is not less than or equal to the reference voltage Vr (NO in step S13), the process returns to step S11.

When the predetermined time elapses in step S11 (YES in step S11), since the pullless operation is not continuously performed, control such as color matching is performed in step S12, and then the process ends.

In step S13, when the monitoring voltage becomes equal to or less than the reference voltage Vr (YES in step S13), the number of pullless operations is counted in step S14, and the count value is a preset numerical value N (for example, two or three times) in step S15. ) Is reached. If N has not been reached (NO in step S15), the process returns to step S01 to determine whether or not the pullless operation is performed again. When the count value reaches N (YES in step S15), since the continuous pullless operation is performed N times, the control such as toning is reset to the initial state in step S16, and the process ends.

In this embodiment, the pullless operation can be accurately and reliably determined. Therefore, when a plurality of lighting fixtures 10 are used as in this embodiment, the color shift of each lighting fixture is eliminated. Can be done. Further, the plurality of lighting fixtures 10 can be reset to the initial state at once by the determination of the pullless operation a plurality of times.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment. For example, the dimmer 4 may be a 4-wire dimmer or a 2-wire dimmer 40 as shown in FIG. Further, although the case where there are a plurality of lighting fixtures has been described, the number of lighting fixtures connected to the phase control type dimmer 4 may be one.
