のトラブルが発生する。2. Description of the Related Art There are a plurality of methods of dimming control for changing the brightness of illumination. Dimming control of an incandescent lamp is directly controlled by a phase control using a semiconductor (thyristor or triac). The scheme is now common. On the other hand, in a fluorescent lamp, in addition to the above phase control method, a weak electric signal of PWM (pulse width modulation) is given to an electronic ballast,
A method of changing the lamp current in accordance with the on-duty of the PWM signal to adjust the light is generally used, and is used for dimming a fluorescent lamp by an inverter circuit for power saving. Therefore, appropriate dimmers must be selected according to the type of lighting load to be dimmed (further, the type of ballast built into the fixture for fluorescent lamps). Various troubles occur, for example, there is no light control, or even if light control is possible, the light controllable range is significantly narrower than the inherent ability of the device.

Since the voltage is also used as the power output and used as a control signal, a high-voltage electric wire, although a signal line is provided between the operation device (phase control type dimmer) 10 and the PWM converter 30, For example, it is necessary to connect a plurality of sets of thick and difficult-to-process power lines such as VVF to the operating device 10. The operation device 10 is often buried in a wall using a switch box or the like, and it is extremely difficult to install a plurality of such power lines in a limited space in the switch box. Even if the ratio of using the phase control voltage as a control signal is higher than the ratio of controlling the power by directly connecting to an incandescent lamp, it is necessary to use an excess and unnecessary thick line because it uses the common terminal with the power line.

The WM dimmer 1 includes an operation unit 11 such as the fader 2 shown in FIG. 1 and a PWM signal generator 12 that generates a PWM signal whose pulse width changes according to the operation amount of the operation unit 11.
It is composed of Some of the plurality of PWM signals output from the PWM signal generator 12 are supplied to the inverter fluorescent lamp 5. This inverter fluorescent lamp 5 has P
The lamp discharge is controlled by the inverter such that the smaller the on-duty of the WM signal is, the brighter the light of the fluorescent lamp is adjusted. The other PWM signals are supplied to a plurality of phase control converters 3.
Is supplied to The PWM signal is insulated and input by the photocoupler 31, rectified and smoothed by the DC converter 32, and temporarily
The voltage is converted into a C voltage, and is input to the microcomputer 34 as a digital value by the A / D converter 33. On the other hand, the firing angle control of the phase control needs to be controlled based on the zero cross point of the AC voltage. Therefore, the zero cross point of the AC power supply 6 is detected by the synchronization circuit 35 and input to the microcomputer 34. The microcomputer 34 outputs a gate signal according to the on-duty of the PWM signal so that the semiconductor switch element 36 (here, triac) conducts from the zero-cross point to the next zero-cross point at a predetermined firing angle, and outputs the on-duty of the PWM signal. This is repeated until changes.

For a constant value of the on-duty of the PWM signal, turn on / off the gate signal to the triac 36 for phase control.
By doing so, a function of controlling lighting and extinguishing of the lighting load is provided. For example, if the on-duty of the PWM signal is 95
When the on-duty of the PWM signal is 5% or less, the illumination load is turned off at the maximum brightness when the on-duty of the PWM signal is 5% or less.

However, if the capability of the microcomputer 34 permits, it is also conceivable to unify them and add a block of only the input / output terminals and the control semiconductor switch element 36 (triac). The method of converting the PWM signal into the phase control voltage is not limited to the method using the A / D converter 33 and the microcomputer 34, but may be, for example, a method using an analog circuit using the RC time constant. .

6に与えて位相制御する方法を採用する。By the way, in a bright region and a dark region of illumination, even if the brightness changes to the same degree, the degree of change in brightness looks different visually, so that the inverter which continuously controls the light output using the PWM signal is used. In a fluorescent lamp, the change in brightness of the fluorescent lamp is not always uniform with respect to the operation amount of the operation device (for example, a stroke of moving the fader 2 of the dimmer 1 in FIG. 1), and the change in brightness is too rapid. Some things are consciously changed so that they are not too slow or too slow. An example is shown in FIG. On the other hand, the fluorescent light and the incandescent light have different light output changes with respect to the input power.
If the phase control firing angle is simply converted linearly with respect to the on-duty of the M signal, the light output of the incandescent lamp changes as shown in FIG. 4B, and does not always look natural. Therefore, the relationship (dimming curve) between the on-duty of the PWM signal and the firing angle of the phase control is obtained in advance and stored as, for example, table data of the microcomputer 34, and the on-duty of the PWM signal is converted into a DC voltage. ,
After A / D conversion and input to the microcomputer 34, the triac 3 outputs a gate signal having a firing angle corresponding to the table data.
6, a phase control method is adopted.

もできる。[0013] Inverter fluorescent lamps (such as our EDH) are designed so that when the PWM signal is lost due to disconnection of the signal line or the like, the lighting is turned on 100% (full lighting).
For this reason, the system of the present embodiment is designed such that the smaller the on-duty of the PWM signal is, the larger (brighter) the light output of the illumination is. However, in the dimming control of the incandescent lamp by the conventional phase control, when the signal from the operation device is disconnected (corresponding to the case where the on-duty of the PWM signal becomes zero in the system of the present invention), it is generally turned off. Therefore, the maximum brightness is provided when the on-duty is 5%, and a circuit for turning off the triac 36 and turning off the light when the on-duty is less than 2% is added. FIG.
In the configuration described above, the output of the microcomputer 34 that drives the gate of the triac 36 is, for example, OFF when the on-duty is 0 to 2%, ON (continuous dimming by phase control) when the on-duty is 2 to 95%, and 95% on-duty. ~ 100
In%, it is always set to ON. Of course, it is also possible to adopt a specification in which 100% light is turned on when the signal is disconnected.

Phase control converter 3
In order to ensure that the PWM dimmer 1 connected to the PWM dimmer 1 is designed for any of these devices, the phase control output is zero when the on-duty of the PWM signal is 95% or less, for example. The table data of the microcomputer 34 is determined so that

%), A duty of 0 to 95% must be passed, and in the on-duty of this range, the lighting load tends to produce a brighter output. Therefore, when passing through this range, bright light is momentarily emitted. A flash phenomenon occurs. Therefore,

An illumination load controlled by a PWM signal using a dimmer equipped with an oscillator and a lighting load controlled by a phase control voltage can be dimmed in the same system.
Compared with a conventional system in which a 100V system phase control voltage is used as a control signal, which is converted to a PWM signal and collectively dimming, the signal voltage is low. It has the effect of being excellent in workability. Therefore, it is particularly useful when an incandescent lamp is added at a site where a fluorescent lamp whose dimming is controlled by the PWM signal is already installed. Also, unlike the case where the actuator is a phase control output, it is not a circuit that directly controls the power, so the conduction current is small, there is no need for a large-capacity heat radiation design, and the signal voltage to be handled can be low, so the insulation distance Therefore, there is an effect that the amount of structural design is greatly reduced, such as that the design considerations are easier than that of the high voltage. Furthermore, since the signal voltage is low and the AC is rectified before the output is generated, noise and power supply distortion to other devices such as generation of radiation noise and outflow of harmonic current when viewed from the actuator alone. The effect is that the influence can be reduced.
