Description of the invention (1) Field of the invention The present invention relates to a dimmer that can perform dimming of a lighting load by controlling a phase of a commercial power source by using an AC-controllable semiconductor element. The description of the related technique is shown in FIG. 30. In the conventional technology (such as Japanese Patent Application Laid-Open No. 4_738 9 1 and Japanese Patent Application Laid-Open No. 9-2 6 6 0 7 5), the dimmer is provided with a bidirectional three-terminal brake fluid C. Hereinafter referred to as a bi-directional triode) TRC, which is inserted between an AC power source Vs and a lighting load La, such as a commercial power source, and controls the power supplied to the lighting load La by controlling the phase of the bi-directional triode TRC to make it adjustable. Light output of lighting load La. In this type of dimmer, a time constant circuit is connected to the main terminals (T1 terminal and T2 terminal) of the bidirectional triode TRC. The time constant circuit is composed of a resistor R21, a variable resistor VR21, and a capacitor C21. The connection point between the varistor VR21 and the capacitor C21 and the gate of the bidirectional transistor TRC is connected as a DIAC as a trigger element. In addition, the variable resistor VR21 is connected in parallel with the series circuit of the resistor R22 and the resistor R23, and the series circuit of the resistor R23 and the capacitor C22 is connected in parallel with the capacitor C21. Assume that the lighting load La is an incandescent lamp. When the power is turned on, the capacitor C21 can be charged through the resistor R21 and the variable resistor VR21. When the voltage at the terminal of the capacitor C21 reaches the breakover voltage of DIAC, the DI AC is turned on. The charge of the capacitor C21 is discharged, and the bidirectional TRC is turned on at this time. Thereafter, when the voltage waveform of the AC power source V s approaches the zero-cross point, the bidirectional TRC cannot maintain the on state because

Therefore, at every half cycle of the voltage waveform of the AC power source VS, the circuit shown at 30 repeats the above operation. Because the variable resistor VR2 丨 can adjust the time when the terminal voltage of the electrical resistor C21 reaches the ON voltage of the DIAC, by adjusting the variable resistor VR2 1, the effective value of the voltage applied to the lighting load u can be adjusted.

Supplement ^ electricity. Charge function ' May "house-4 hysteresis (hys soil eresis) phenomenon of characteristic rhyme. In the circuit shown in Figure 30, if the on-voltage of DIAC is not reached, the potential of capacitor C21 cannot make the bi-directional transistor trc turn on, so that when the frequency of the AC power source V s is different, the capacitor c The charging time of 21 is different, so the dimming characteristics will be very different because the frequency of the AC power supply VS is 50Hz or 60HZ. It will also return components with larger nature (such as DIAC, variable resistor VR, etc.) ', which will make the non-uniformity of the clipping curve larger. Therefore, the disadvantage of the circuit shown in FIG. 30 is that: the rate is different. (Such as 50Hz and 60HZ) or the structure # & 3 jjLd ', which makes the unevenness of the dimming curve greater. In addition, the circuit of FIG. 30 has a disadvantage: although the above hysteresis characteristics can be improved by the resistor R22, the resistor R23, and the capacitor 022, but the time constant of the time constant circuit in the circuit of FIG. 30 will be affected by the power supply voltage. The peak value changes. Moreover, because the

Page 5 _ 411729 _ V. Description of the invention (3) The peak value of the voltage of the load La changes, so that the light of the lighting load La changes according to the rate of change of the series. For example, when the power supply voltage is changed from the state of 100V shown in FIG. 31 (a) to the state of 90V shown in FIG. 31 (b), the period during which the voltage is applied to the lighting load La is shortened from 3.02 milliseconds to 2. 4 2 ms. In addition, when the state of 100 V shown in FIG. 31 (a) is changed to the state of 110 V shown in FIG. 31 (c), the period during which the voltage is applied to the lighting load La is extended from 3.02 milliseconds. To 3. 46 ms. In short, its disadvantages are: the rate of change in the light output of Zhao Xu La is greater than the rate of power of the power source. In addition, the scale of the vertical axis in FIG. 31 is 50 V / div, and the scale of the horizontal drawing is 2 ms / d i v. Also, in the circuit of FIG. 30, a series circuit of a resistor R23 and a capacitor C22 is connected in parallel with a voltage stabilizing circuit. The voltage stabilizing circuit is formed by a pair of Zener diodes ZD1 and ZD2 connected in antiparallel. In this way, the voltage across the series circuit of the variable resistor VR21 and the capacitor C21 can be kept constant, and the time constant of the time constant circuit can be suppressed from changing due to the peak value of the power supply voltage. However, when the electric power is abandoned, "J. pressure protection and recovery __ will change, and _ 夙 -applied-to-gaming-negative-charge La a cover changes, so the change ratio of the output of the purpose of the charge of La La. The present invention is based on solving the above-mentioned problems, and its object is to provide a dimmer with less unevenness in dimming characteristics. Invention

In addition, the capacitor C1 is connected in parallel with the resistor R6; the resistor R7 is connected in parallel with the diode D3; and, the contact between the resistor R6 and R7 and the base of the transistor Q1 is connected with the capacitor C3 as a noise absorption capacitor 1 In addition, 'the contact point between the resistor R9 and the variable resistor VR and the contact point between the variable resistor VR and the resistor R4' is connected to a resistor R10 which is a fixed resistor for brightness level adjustment. In short, 'in this embodiment, a time constant circuit is connected between the output terminals of the diode bridge DB, which is formed by a series circuit of a resistor R5 and a capacitor C 1' a reference voltage generating circuit, which is a resistor R3 Series circuit of variable resistor vr and resistor R4. At the same time, a comparison circuit with a crystal Q1 is inserted between one terminal of the capacitor ^ of the time constant circuit and the variable resistor VR of the reference voltage generating circuit. ,

This series circuit including a resistor m and a capacitor C2 is connected between the main terminals of the bidirectional TRC transistor; the transistor Q2 '当When the voltage difference between the terminal voltage of the capacitor C1 inserted between the output terminals of the diode lion and the reference voltage generated by the reference voltage generating circuit exceeds a set value, the transistor is turned on. When the transistor is turned on, the borrow The discharge current of the capacitor C2 transmits a trigger signal to the gate of the bidirectional transistor 71? (:. In this embodiment, when the power is turned on, in addition to storing the charge in the capacitor C2 through the resistor, it also passes the resistor at the same time. R1 and R5 store the charge in capacitor ci. Now, suppose vi is the terminal voltage of capacitor 1C1, the voltage between the base of V2 transistor Q1 and the emitter of transistor Q2 (hereinafter referred to as the illumination voltage), when the terminal voltage Only when vi reaches a predetermined value greater than the control voltage V2 (that is, the voltage difference between the terminal voltage VI and the reference voltage exceeds a set value ', the crystal Q1 will be turned on, so that the charge of the capacitor C1 flows through the transistor 01 and = R8' to The base of the crystal Q2 turns on the transistor Q2. When the electricity is turned on, the charge of the capacitor C2 passes the resistance β1ι and the electric Q2 to transmit a trigger signal to the interrogator of the bidirectional triode TRC, so that the ^ pole TRC Turn on and apply voltage to the lighting load La ^ ° 2 Figure 3 shows the operation of the circuit shown in Figure 1. Figure 2 shows the circuit constant. Figure 3 (a) shows the time when the electric power of the AC power source Vs is ΐοον Fig. 3 (b) shows the action when the voltage of the AC power source Vs is 90v, and the "operation" means the action when the voltage of the AC power source Vs is 110V; V3 means C) the main terminal of the triode TRC The inter-voltage 'V1 represents the time constant voltage " the terminal voltage' V2 of the bidirectional capacitor C1 'is a table τρ comparison power. Figure 3

_4ii72D_ 5. Description of the invention (19) The degree is 2 milliseconds / div, and the vertical scale of V3 is 50V / div; the vertical scale of V1 and V2 is 100mV / div. Although the reference voltage V2 is a divided voltage waveform of the full-wave rectified waveform of the diode bridge DB, since V1 is the terminal voltage of the capacitor C1, it rises slowly compared to the control voltage V2. It is clear from FIG. 3 that if the power supply voltage changes, the control voltage will change, and the phase of the on-state bipolar TRC will change. That is, although the time variation of the terminal voltage V 1 of the capacitor C 1 provided in the time constant circuit is affected by the fluctuation of the power supply voltage, the voltage between the DC output terminals of the diode bridge DB will be divided by the control voltage. Voltage, it will reflect the fluctuation of the power supply voltage, so if the power supply voltage drops, the control voltage will also drop. Therefore, in the example of FIG. 3, when the power supply voltage is 100V, the ON period of the bidirectional triode RC is 3.02 milliseconds; 3.0 milliseconds at 90 V; 3.04 at 1 10 V Milliseconds; therefore, it can be seen that even if the power supply voltage changes, the phase angle of the bidirectional TRC will hardly change. In other words, in this embodiment, even if the power supply voltage is changed, the phase angle that can trigger the bidirectional transistor TRC is hardly changed, so the light output variation of the lighting load La caused by the power supply voltage can be suppressed. In this embodiment, when the AC power source V s changes, the reference voltage for determining the reference voltage V 2 also changes similarly to the AC power source V s (for example, when the voltage power source decreases, the charging voltage of the capacitor C1 becomes low, but on the other hand The reference voltage also becomes lower), so there is less variation in the on-time of the bidirectional transistor TRC, and there is less variation in the output voltage. In addition, whether the frequency of the AC power source V s is 50 Η z or 60 0 0 ζ, the variation of the dimming characteristics is small. In addition, before the AC power source V s will reach the zero crossing, because the base potential of the transistor Q1 is close to 0V, the transistor Q1 will conduct

Page 22 ^^ 1729 V. Description of the Invention (20) The charge of 彳. Therefore, the phenomenon that the capacitor C1 is reset is generated every half cycle, and the characteristic of the capacitor C1 is reset. Hysteresis can be removed once, so when the voltage at the cli terminal of the container reaches a certain value, in this embodiment, it is not when but by comparing the control voltage v 2 and the bipolar TRC will be turned on. In time, the voltage across the terminal of the capacitor C1 is different due to the unevenness of the dimming characteristics, so the frequency of the AC power source V s is different. 1 'is smaller than the conventional circuit shown in FIG. 30. In addition, in this embodiment, the charge of the capacitor C1 is discharged and reset every half cycle, so it is lagging. Meanwhile, in this embodiment, only the β-variable resistor is used as a voltage dividing resistor, which can determine the base potential of the transistor Q1, and the charging of the capacitor C1 is performed through the fixed resistors R1 and R5 with less constant non-uniformity. . Therefore, even if the resistance value of the variable resistor VR is non-uniform, since the base potential of the transistor Q 1 is determined by its voltage division ratio, there is almost no non-uniformity in its dimming characteristics. In addition, in this embodiment, between the connection point of the resistor R 9 and the variable resistor v R and the contact point of the variable resistor VR and the resistor R 4, the resistor R 10 is connected, and the resistance value of the resistor R 10 can be set appropriately. , Adjust the variable resistor "to the minimum variable position when operating in the direction of ί 22, the lighting brightness output voltage is 5% ν, the lighting load La = / 'When the resistance R10 to the lighting load La, its For lighting load = 'But if the load U connected to 3_ becomes dimly lit, the output voltage becomes 2 watts, and lighting. In addition, in this embodiment, the coupling of the lightning BDC ^ 0 1 Φ 6, Between the connection point of the resistors R 6 and R 7 and the transistor electrode, a capacitor C3 is connected, and the capacitor d is overlapped by the capacitor C3.

^ 1729 V. Description of the invention (21) Noise from the source or noise emitted from the air provides a by-pass to increase the noise capacity, because it can prevent the transistor Q1 caused by the noise. The misoperation, so no misoperation "caused. The phase angle shift of the dual U polar body TRC caused it. The condition of the lighting I and La flickering. In addition, the anode of the above-mentioned diode D3 is connected to one end of the capacitor C1, and its cathode is connected to the emitter of the transistor Q1. Therefore, the withstand voltage can be maintained by the diode D3, so the base and the emitter can be used. The element with lower reverse bias voltage is used as transistor Q1. In addition, if the reverse leakage current with the smaller leakage current is used as the diode D 3, when no forward current flows to the diode D 3, the potential of the emitter of the transistor Q 1 becomes a floating state, so that the emitter The potential of the electrode is unstable and may cause malfunction. However, by connecting diode D3 and resistor R7 in parallel, the potential of the emitter of transistor Q1 can be fixed and the malfunction of transistor Q1 can be prevented. In addition, as shown in FIG. 2, using the larger resistance value as the resistor R 7 can maintain the reverse bias withstand voltage suppression effect of the diode D 3, so the restriction on the diode D 3 becomes less and can be used arbitrarily. Characteristics of the diode. In addition, by setting the circuit constant, although the DC voltage on the DC output side of the diode bridge DB sometimes becomes high, the variable resistor VR rarely has a high rated voltage. However, in this embodiment, the voltage is adjusted by reducing the impedance on the DC output terminal side of the diode bridge D B by connecting the resistance 12 between the DC output terminals of the diode bridge D B. Therefore, the charge of capacitor C2 can also be adjusted, and the trigger current can be controlled. In addition, as described above, in this embodiment, the capacitors C 5 and C 6, the choke coil L and the resistor R 1 3 constitute a noise filter, which can prevent a bidirectional three-pole

Page 24 ^ 1729 V. Description of the invention (22) The noise generated by the switching of the body T R C is output to the AC power source V s or the lighting load La. In addition, as shown in FIG. 5, although the noise filter can also be constituted only by the capacitor C 5 and the choke coil L, when the noise filter is turned on, due to the LC resonance of the choke coil L and the capacitor C5, The resonance current shown in Fig. 6, so the resonance current is zero crossing. Due to the structure of the bidirectional TRC, the resonance current may be closed due to zero crossing. In order to prevent this phenomenon, in this embodiment, a resistor R13 is inserted, and it is connected in series with the capacitor C5 so that the resonance current does not generate a zero crossing as shown in FIG. 7. This can reduce the characteristic limit of the bidirectional triode TRC and can be used cheaper. Bidirectional TRC. At the same time, the performance of the noise filter is poor, so the resistor R 1 3 is connected in parallel with the capacitor C6. L Wait until the thunder container C6 can be used as a bypass for high-frequency noise components. In addition, as shown in FIG. 8 to FIG. 11, the dimmer of this embodiment includes a body 1 mounted on a mounting frame 40 having a size that is in accordance with JIS specifications for large-scale connection wiring devices.
