Specifically, controller 2 has switch portion 21, when start-up connector 2, or change from ligthing paraphernalia 3 produce light light quantity and photochromic or one of them time, the conducting of switch portion 21 to the alternating voltage supplied by source power supply 5 controls, and makes the waveform of the alternating voltage supplied from source power supply 5 have the pattern of the breach set in control signal setting regions.The alternating voltage with the pattern of this breach transmits to ligthing paraphernalia 3.The alternating voltage of pattern jaggy for tool is used as the luminous energy by ligthing paraphernalia 3, on the other hand, by the light quantity of this light and the photochromic light quantity that meets the pattern of this breach and photochromic.That is, using being included in the pattern of the breach of control signal setting regions as being used for setting light quantity and photochromic signal, transmit to ligthing paraphernalia 3.

As mentioned above, for setting the light quantity of the light produced from ligthing paraphernalia 3 and photochromic signal, transmit to ligthing paraphernalia 3 from controller 2 via power line 4a, 4b.Therefore, without the need to laying the dedicated signal lines being used for transmission of control signals, the control of light modulation toning can be carried out.

Below, illuminator 1 is further described.Controller 2 is four-wire type controllers, and it is layed in indoor wall etc.Ligthing paraphernalia 3 is such as Down lamp or indirect lighting.Controller 2 and ligthing paraphernalia 3 are electrically connected with source power supply 5 via power line 4a, 4b respectively.Source power supply 5 is powered to controller 2 and ligthing paraphernalia 3 via power line 4a, 4b.

Controller 2 possesses switch portion 21, drive division 22, input part 23, display part 24 and the first control part 25.

Switch portion 21 gets involved and is arranged on power line 4a.The conducting of switch portion 21 to the alternating voltage supplied from source power supply 5 controls, and makes the waveform of the alternating voltage supplied from source power supply 5 have the pattern of the breach set in control signal setting regions.In addition, the region of switch portion 21 beyond control signal setting regions, makes alternating voltage continue through.Drive division 22 generates the drive singal being used for driving switch portion 21.First control part 25 is via the action in drive division 22 control switch portion 21.

The switch element that switch portion 21 comprises, is preferably semiconductor switch.In the present embodiment, because source power supply 5 is used as power supply, therefore as the switch element that switch portion 21 comprises, preferably use an example, the i.e. bidirectional thyristor (i.e. so-called bidirectional triode thyristor (triac)) of semiconductor switch.In the present embodiment, use bidirectional thyristor as the switch of switch portion 21.Fig. 2 is the figure of the example representing switch portion 21.As shown in Figure 2, drive division 22 is electrically connected with the gate pole (gate) of bidirectional thyristor 6.Drive division 22 generates the drive singal of the gate pole for driving bidirectional thyristor 6.Specifically, drive division 22 generates the drive singal making the pulse type of bidirectional thyristor 6 conducting (turnon).

Get back to Fig. 1, the input part 23 of controller 2 is User's Interface, such as, comprise multiple button.User can make instruction to the light quantity and photochromic middle at least one party changing the light produced from ligthing paraphernalia 3 via input part 23.The change instruction of user inputs to the first control part 25 via input part 23.

First control part 25 is such as microcomputer.First control part 25 sets the pattern of breach according to the change instruction of user.Further, the first control part 25 controls via the action of drive division 22 pairs of switch portion 21, makes the waveform of alternating voltage have the pattern of the breach set in control signal setting regions.Specifically, the first control part 25 set as breach pattern, represent light quantity the first pattern and represent the second photochromic pattern.The setting of the first pattern and the second pattern, such as, realize also can by storing check table (look-uptable) at the storage part 25a of the first control part 25.

Such as, when user makes amount of light and photochromic change instruction, the first control part 25 sets first and second pattern, and first and second pattern described represents light quantity indicated by user and photochromic respectively.In addition, when user only makes the change instruction of amount of light, the first control part 25 to the first pattern of the light quantity represented indicated by user, and represents that current the second photochromic pattern sets.

First control part 25 via input part 23 by user input the light quantity of (registration) and photochromic information is stored in storage part 25a.Thus, such as, when the power supply of controller 2 is connected, the first control part 25 can use the light quantity and photochromic information that are stored in storage part 25a to set the pattern of breach.Accordingly, when the power is turned on, light quantity and photochromic light that user registered last time can be reappeared.

In addition, the first control part 25 controls display part 24, thus, is presented at the light quantity and photochromic information of visually assisting user to register at display part 24.Specifically, the initial stage of display part 24 after house or office etc. arrange illuminator 1, the light quantity of display defined and photochromic information.Light quantity and the photochromic information of defined are stored in storage part 25a, the stage in the early stage, irradiate the light quantity of this defined and photochromic light from ligthing paraphernalia 3.Afterwards, display part 24, according to the change instruction inputted via input part 23, shows light quantity and photochromic information.Thus, user can observe display part 24, while the light quantity and photochromic desired by registration.

In addition, in the present embodiment, because source power supply 5 is used as power supply, therefore controller 2 possesses zero passage detection portion 26.Zero passage detection portion 26 is for detecting the zero crossing (zero-crosspoint) of alternating voltage waveform, first control part 25 based on the testing result in zero passage detection portion 26, the action (conducting (turnon) of bidirectional thyristor 6) in control switch portion 21.Specifically, the first control part 25, based on the testing result in zero passage detection portion 26, controls the moment (timing) that drive division 22 generates drive singal.

Fig. 3 represents that drive division 22 generates the figure of an example of drive singal 61.Specifically, Fig. 3 (a) expression represents drive singal 61 by the alternating voltage 51, Fig. 3 (b) of switch portion 21.

As shown in Figure 3, when waveform formation breach 53 at alternating voltage 51, the moment T arrived after the zero crossing 52 the half-wave from alternating voltage 51 is delayed the stipulated time, starts to generate drive singal 61 (drive singal 61 rises).In the present embodiment, the switch element due to switch portion 21 is bidirectional thyristor 6, and therefore bidirectional thyristor 6 is not when zero crossing 52 is triggered, and bidirectional thyristor 6 turns off (turnoff) at zero crossing 52.Therefore, the moment T arrived after zero crossing 52 the half-wave from alternating voltage 51 is delayed the stipulated time, drive singal 61 is made to increase, thus, the moment T arrived after the zero crossing 52 of bidirectional thyristor 6 the half-wave from alternating voltage 51 is delayed the stipulated time, forms conducting (turnon).Thus, at the breach 53 of the waveform formation Rack of alternating voltage 51.

The Trigger Angle of bidirectional thyristor 6 is made to be less than 90 degree.Thus, in the waveform of the half-wave of alternating voltage 51, the zero crossing 52 from this half-wave is cut open to the position of the phase angle 90 degree of this half-wave not enough.In this wise, by making the Trigger Angle of bidirectional thyristor 6 be less than 90 degree, can the generation of restraint speckle.More preferably, the zero crossing 52 from the half-wave of alternating voltage 51, in the scope of 2.5m second, makes bidirectional thyristor 6 trigger.Thus, in the waveform of the half-wave of alternating voltage 51, be cut open till position within zero crossing 52 to the 2.5m second from this half-wave, therefore, it is possible to suppress the loss being sent to the electric power of ligthing paraphernalia 3.

On the other hand, when switch portion 21 makes the half-wave conducting of alternating voltage 51, the zero crossing 52 that drive singal 61 starts at this half-wave rises, and declines before the zero crossing 52 terminated at this half-wave.That is, the first control part 25 pairs of drive divisions 22 control, and make the zero crossing 52 from the half-wave of alternating voltage 51, to before the zero crossing 52 that this half-wave terminates, generate drive singal 61.The moment that drive singal 61 is declined judges the frequency of alternating voltage 51 by the first control part 25 and determines.

Above controller 2 is illustrated.In addition, controller 2 possesses not shown power circuit.This power circuit is electrically connected with power line 4a, 4b, and based on the alternating voltage 51 that power line 4a, 4b send, the electric power needed for action of formation controller 2 each several part.In addition, input part 23 can be made up of touch-screen.Touch-screen can be arranged on display part 24.In addition, input part 23 can comprise the ultrared infrared receiver portion that can receive and send from infrared ray remote controllers etc.In this case, from the infrared ray coded signal that infrared ray remote controllers etc. send, the first control part 25 is transferred to via infrared receiver portion.Such as, when the framework of infrared ray remote controllers arranges light quantity raise button (upbutton), light quantity reduction button (downbutton), photochromic raise button and photochromic reduction button, user often press next time arbitrary button time, the information of the light quantity that user makes or photochromic change instruction, by infrared ray coded signal, transfers to the first control part 25.Therefore, such as, when user presses light quantity minimizing button, the first control part 25 is to the first pattern of the light quantity represented indicated by user and represent that current the second photochromic pattern sets.

Then, ligthing paraphernalia 3 is described.As shown in Figure 1, ligthing paraphernalia 3 possesses lighting power feeding section 31 and signal generating unit 32.Lighting power feeding section 31 is electrically connected with power line 4a, 4b, and based on the alternating voltage 51 sent via switch portion 21, supplies electric power to a lamp load 340.Signal generating unit 32 is also electrically connected with power line 4a, 4b, and the alternating voltage 51 transmitted to ligthing paraphernalia 3 via switch portion 21, is also transferred into signal generating unit 32.In the present embodiment, through the alternating voltage 51 of the rectification circuit 310 included by lighting power feeding section 31, signal generating unit 32 is transferred into.Therefore, the voltage being sent to signal generating unit 32 is the voltage after rectification.

The pattern of the breach 53 that signal generating unit 32 has based on alternating voltage 51 (voltage after rectification), generates control signal.That is, signal generating unit 32 uses part in the waveform of alternating voltage 51, control signal setting regions to generate control signal.This control signal carries out to a lamp load 340 signal that electric power supplies action by lighting power feeding section 31 for controlling.

In the present embodiment, some lamp load 340, as illumination component, comprises transmitting and has the multi-colored led of different photochromic light.Such as illumination component, the LED of 5000 Kelvins (cool colour) and the LED of 2700 Kelvins (warm colour) can be used.In the present embodiment, put lamp load 340 and comprise dual-colored LED.In this wise, by using, there is different photochromic LED, the control of light modulation toning can be realized.

Connection one example of LED341 has been shown in Fig. 4 (a) and Fig. 4 (b).As shown in Fig. 4 (a) and Fig. 4 (b), mutually homochromy LED341 be electrically connected in series also can, electrical connection in parallel also can.Or some lamp load 340 comprises a LED341 also can to often kind photochromic.Multi-colored led 341 preferred equivalent arrangements when overlooking.Thus, each photochromic light is mixed equably, therefore to the light quantity of the light that a lamp load 340 produces and photochromicly can carry out high-precision adjustment.

Get back to Fig. 1, in the present embodiment, the illumination component due to a lamp load 340 is LED341, and therefore lighting power feeding section 31 generates constant current based on the alternating voltage 51 sent via switch portion 21.In the present embodiment, due to source power supply 5 is used as power supply, therefore lighting power feeding section 31 possesses: rectification circuit 310; Smoothing circuit 320; And correspond respectively to the LED341 of each look and the constant-current circuit 330 (the first constant-current circuit 330a and the second constant-current circuit 330b) arranged.

Rectification circuit 310 carries out rectification to the alternating voltage 51 sent via switch portion 21.Rectification circuit 310 is suitably full-wave rectifying circuit.In the present embodiment, rectification circuit 310 is full-wave rectifying circuit.Smoothing circuit 320 is for making the output smoothing of rectification circuit 310.One example of smoothing circuit 320 has been shown in Fig. 5.As shown in Figure 5, smoothing circuit 320 also can be made up of diode 321 and electrochemical capacitor 322.

Get back to Fig. 1, the alternating voltage 51 sent via switch portion 21, be converted to direct voltage by rectification circuit 310 and smoothing circuit 320.Each constant-current circuit 330 generates constant current according to the output (direct voltage) of smoothing circuit 320 respectively.By this constant current, supply electric power to a lamp load 340 (LED341).

Fig. 6 is the figure of the part that constant-current circuit 330 1 example is shown, represents the structure of the peripheral circuit of some lamp load 340 (LED341).As shown in Figure 6, constant-current circuit 330 can comprise: three resistors 331,332,333; NchMOSFET334; Coil 335; Diode 336; Iron-core coil 337; And electrochemical capacitor 338.Electrochemical capacitor 338 is charged by the output of smoothing circuit 320.According to the signal from signal generating unit 32, NchMOSFET334 repeats conducting (turnon) and turns off, and thus, electrochemical capacitor 338 repeats charging and discharging.Thus, constant current flows into LED341, thus LED341 is luminous.

Regulating the light quantity of light that produces from a lamp load 340 and photochromic, is that the current value by controlling the constant current flowing into assorted LED341 realizes.Therefore, signal generating unit 32 generate as control signal, for conducting (on) time of control NchMOSFET334 and the signal of shutoff (off) time.

Fig. 7 is the waveform that the figure of the example that signal generating unit 32 is shown, Fig. 8 show the signal of each several part generation of the signal generating unit 32 shown in Fig. 7.When control NchMOSFET334 (example of switch element) ON time and turn-off time, signal generating unit 32 also can be circuit structure as shown in Figure 7.Signal generating unit 32 shown in Fig. 7 possesses waveform transformation circuit 70 and the second control part 75.In addition, as shown in Figure 7, to the second control part 75 supply line voltage Vcc.Power source voltage Vcc is generated by power circuit (not shown), and described power circuit is identical with controller 2, is arranged on ligthing paraphernalia 3.

Waveform transformation circuit 70, generates pulse signal by the output (voltage after rectification) of rectification circuit 310 and threshold value being compared.Waveform transformation circuit 70 can possess three resistance 71,72,73 and bipolar transistor 74.Resistance 71,72 is configured for bleeder circuit rectified voltage being carried out to dividing potential drop.The output voltage of this bleeder circuit puts on the base stage (base) of bipolar transistor 74.

Fig. 8 (a) shows an example of the waveform of the voltage 81 (output voltage of bleeder circuit) putting on bipolar transistor 74 base stage.The output voltage 81 of bleeder circuit comprises breach 53.Bipolar transistor 74, according to the magnitude relationship between the threshold value of its base stage and the output voltage 81 of bleeder circuit, repeats conducting (turnon) and turns off.Thus, on the collector electrode (collector) of bipolar transistor 74 and the tie point of resistance 73, generate the pulse signal 83 as shown in Fig. 8 (b).Fig. 8 (b) shows an example of pulse signal 83.In addition, resistance 73 is pull-up (pull-up) resistance.

As shown in Fig. 8 (a) and Fig. 8 (b), near the position 82 that the zero crossing 52 with alternating voltage 51 is corresponding, the output voltage 81 of bleeder circuit is lower than base stage threshold value, and pulse signal 83 is L level (level).Specifically, pulse signal 83 comprises two kinds of L level, and described two kinds of L level have the width corresponding with the presence or absence of breach 53.This is because, be formed with breach 53 part, the output voltage 81 of bleeder circuit is becoming longer lower than the time of base stage threshold value with not being formed with compared with breach 53 part.That is, be not formed with breach 53 part, producing the first L level 83a with the first width, be formed with breach 53 part, produce the second L level 83b with the second width being longer than the first width.Pulse signal 83 generated like this transfers to the second control part 75.

Second control part 75 is such as microcomputer.The collector electrode of voltage from bipolar transistor 74 and the tie point of resistance 73, put on the second control part 75.That is, pulse signal 83 transfers to the second control part 75.Two kinds of L level (the first L level 83a and the second L level 83b) that second control part 75 comprises according to pulse signal 83 and generate digital signal.

Specifically, pulse signal 83 and threshold value compare by the second control part 75, judge the width of L level.And, second control part 75 is based on the width of L level, judge that this L level is the first L level 83a or the second L level 83b, thus generate and correspond to the first L level 83a and be worth and be formed as " 0 ", be worth corresponding to the second L level 83b the digital signal being formed as " 1 ".Namely, by being controlled the conducting of alternating voltage 51 by controller 2 (switch portion 21), all or part of waveform of the half-wave of the alternating voltage 51 that control signal setting regions is comprised has breach 53, thus the signal suitable with the data of bit (bit) size with the half-wave unit transmission of alternating voltage 51 to ligthing paraphernalia 3.At this, the second control part 75, such as, compare pulse signal 83 and threshold value every several 100 μ, judge the width of the L level of pulse signal 83 thus second.In this wise, by pulse signal 83 is compared with threshold value meticulously, can the impact of noise that comprises of suppressor pulse signal 83.

Preferably, till before detecting the second L level 83b, the second control part 75 obtains the width ratio of time upper adjacent L level, and judges that L level is the first L level 83a or the second L level 83b.That is, the width ratio of certain L level is, with the ratio compared with the width of a L level before it on the time.Specifically, when value in the first scope that the width ratio of the L level obtained is regulation, the second control part 75 judges that this L level is the first L level 83a.On the other hand, when value in the second scope that the width ratio of the L level obtained is regulation, the second control part 75 judges that this L level is the second L level 83b.First range set is for being narrower than the second scope.And, after detecting the second L level 83b, and before detecting the first L level 83a till, the second control part 75 obtain as L level width ratio, the second L level 83b is relative to the ratio of the width of previous L level (the first L level 83a).In addition, when the value of the L level width ratio obtained is for " 1 ", the second control part 75 judges that this L level is that the first L level 83a also can.

When obtaining L level width ratio like this, preferably, controller 2 not immediately at the waveform formation breach 53 of alternating voltage 51, but repeatedly generates the first L level 83a continuously after power supply is connected on pulse signal 83.In addition, after a control signal setting regions terminates, controller 2 does not form breach 53 on the waveform of alternating voltage 51, but repeatedly generates the first L level 83a continuously on pulse signal 83.

By obtaining the width ratio of L level as mentioned above, cause the width of L level to change even if Yin Wendu rises, the second control part 75 also can read pulse signal 83 (pattern of breach 53).Fig. 9 (a) shows an example of the waveform of the pulse signal 83 under usual state.As shown in Fig. 9 (a), usually, the width W 1 of the first L level 83a and the width W 2 of the second L level 83b are fixing.On the other hand, as shown in the double dot dash line of Fig. 9 (b), Yin Wendu rises and makes the decline generation passivation of pulse signal 83, the situation that the width of the width W 1 and the second L level 83b that there will be the first L level 83a thus changes.Therefore, the width W 1 of the first L level 83a judged by the second control part 75 and the width W 2 of the second L level 83b are compared with fixed value respectively, and then judge that L level is the first L level 83a or the second L level 83b, in this case, if Yin Wendu rises and makes the waveform widths of pulse signal 83 change, then there is the possibility that the second control part 75 cannot read pulse signal 83.To this, even if Yin Wendu rises and makes the decline generation passivation of pulse signal 83, the change of each L level width is also roughly the same degree, therefore, by obtaining the width ratio of L level, can read pulse signal 83.

If generation digital signal, second control part 75 based on the content (data) of this digital signal, can generate and is used for ON time and the signal of turn-off time (control signal) that control is contained in each NchMOSFET334 of each constant-current circuit 330 (the first constant-current circuit 330a and the second constant-current circuit 330b) respectively.Specifically, control signal is pulse voltage, and determines the pulse duration of the pulse voltage transmitted to each constant-current circuit 330a, 330b according to the content of digital signal.Therefore, flowing into the current value of the constant current of the LED341 being contained in each constant-current circuit 330a, 330b, for corresponding to the value of the content of digital signal, being namely formed as the value of the pattern corresponding to breach 53.About the setting of the pulse duration of pulse voltage, such as, realize also can by storing check table at the storage part 75a of the second control part 75.

Then, with reference to Fig. 1-Figure 13, to the light quantity of a lamp load 340 and photochromic at least one change time, the action of illuminator 1 is described.Figure 10-Figure 12 represents the signal waveform of each several part of illuminator 1.

The sinuous alternating voltage 51 shown in Figure 10 (a) is supplied from source power supply 5 to power line 4a, 4b.If change the light produced from a lamp load 340 light quantity and photochromic at least one instruction input via input part 23, then the first control part 25 is according to the action changing indicating control switch portion 21.Thus, the conducting of switch portion 21 pairs of alternating voltages 51 controls, and makes the waveform of alternating voltage 51 have the pattern of the breach 53 set in control signal setting regions.In addition, the action of the first control part 25 pairs of switch portion 21 controls, and makes the region of alternating voltage 51 beyond control signal setting regions continue through switch portion 21.

In the present embodiment, the conducting of switch portion 21 pairs of alternating voltages 51 controls, and the pattern of breach 53 is comprised and represents the first pattern of light quantity and represent the second photochromic pattern.Specifically, the conducting of switch portion 21 pairs of alternating voltages 51 controls, and makes the waveform of alternating voltage 51 have the breach 53 of multiple first pattern continuously, afterwards, the conducting of alternating voltage 51 is controlled, makes the waveform of alternating voltage 51 have the breach 53 of multiple second pattern continuously.At this, to the waveform of alternating voltage 51 after the first pattern is cut away twice continuously, the second pattern is described by the situation of cutting away twice continuously.

Figure 10 (b) shows an example of the waveform of the alternating voltage 51 by switch portion 21.As shown in Figure 10 (b), switch portion 21 temporarily disconnected alternating voltage 51, thus at the waveform formation breach 53 of alternating voltage 51.Afterwards, the alternating voltage 51 with breach 53 is sent to the rectification circuit 310 of ligthing paraphernalia 3.

Rectification circuit 310 carries out rectification to the alternating voltage 51 sent via switch portion 21.Figure 10 (c) shows an example of the output (voltage 81 after rectification) of rectification circuit 310.Smoothing circuit 320 makes the output of rectification circuit 310 become smoothing.Figure 10 (d) shows an example of the output of smoothing circuit 320.As shown in Figure 10 (d), direct voltage 101 can be obtained by smoothing circuit 320.Therefore, direct voltage 101 is supplied by smoothing circuit 320 to each constant-current circuit 330.

On the other hand, signal generating unit 32 is sent to by the voltage 81 after rectification circuit 310 carries out rectification.The pattern of the breach 53 that signal generating unit 32 has based on voltage 81, carries out the change of control signal to each assorted LED341.In the present embodiment, waveform transformation circuit 70 generates the pulse signal 83 (with reference to Fig. 8) corresponding with the pattern of breach 53.Further, the second control part 75, according to the two kinds of L level (the first L level 83a and the second L level 83b) being contained in pulse signal 83, generates digital signal.Specifically, as shown in figure 11, the first digital signal (light quantity numeric data code (datacode) 111) that the double generation of second control part 75 is corresponding with the breach 53 of the first pattern, the second digital signal (photochromic numeric data code 112) that then double generation is corresponding with the breach 53 of the second pattern.

Whether the second control part 75 is identical according to two light quantity numeric data codes 111, judges whether effective the light quantity of the light produced from a lamp load 340 regulates.Identical with it, whether the second control part 75 is identical according to two photochromic numeric data codes 112, judges that whether the photochromic adjustment of the light produced from a lamp load 340 is effective.Further, the second control part 75 regulates according to light quantity and the whether effective judged result of photochromic adjustment respectively, generates control signal.

Specifically, when two light quantity numeric data code 111 is identical and two photochromic numeric data codes 112 are identical time, second control part 75, based on light quantity numeric data code 111 and photochromic numeric data code 112, generates the control signal (pulse voltage) of the action for controlling each constant-current circuit 330 respectively.That is, the second control part 75 determines the pulse duration of the pulse voltage transmitted to each constant-current circuit 330 (the first constant-current circuit 330a and the second constant-current circuit 330b).Further, then controller 2 before the waveform formation breach 53 of alternating voltage 51 till, the second control part 75 is sent to corresponding constant-current circuit 330 by having respectively by each pulse voltage of the pulse duration determined.Thus, according to the pattern of the breach 53 that control signal setting regions comprises, be sent in the control signal of each constant-current circuit 330 that at least one is changed.This control signal is, makes the signal of the light quantity of a lamp load 340 and photochromic level corresponding with light quantity numeric data code 111 and photochromic numeric data code 112 respectively.In addition, light quantity numeric data code 111 and photochromic numeric data code 112 are stored in storage part 75a by the second control part 75.

On the other hand, when two light quantity numeric data code 111 is identical and two photochromic numeric data codes 112 are inconsistent time, second control part 75, based on this light quantity numeric data code 111 generated and the photochromic numeric data code 112 that is stored in storage part 75a, determines the pulse duration of the pulse voltage transmitted to each constant-current circuit 330.When two light quantity numeric data codes 111 are inconsistent and two photochromic numeric data codes 112 are consistent, also determine the pulse duration of pulse voltage after the same method.In addition, when two light quantity numeric data codes 111 and two photochromic numeric data codes 112 all inconsistent time, the second control part 75 does not change control signal.

Figure 12 shows the pattern of the breach 53 that signal generating unit 32 (the second control part 75) comprises corresponding to control signal setting regions and an example of the digital signal that generates.Figure 12 is the figure schematically showing digital signal, the value of the numeric representation digital signal of " 0 " and " 1 " that each light quantity numeric data code 111 and each photochromic numeric data code 112 comprise.As shown in figure 12, in the present embodiment, bit (bit) number of light quantity numeric data code 111 and photochromic numeric data code 112 is six bits.Namely, the conducting of switch portion 21 pairs of alternating voltages 51 controls, make all or part of waveform of continuous print 24 half-waves of alternating voltage 51 have breach 53, generate light quantity numeric data code 111 and photochromic numeric data code 112 twice respectively in signal generating unit 32 thus.Accordingly, according to the quantity determination control signal setting regions of the half-wave of alternating voltage 51.

In addition, each light quantity numeric data code 111 and the respective foremost value of each photochromic numeric data code 112 are " 1 ".Thus, the second control part 75 can detect each light quantity numeric data code 111 and the respective most prostatitis part of each photochromic numeric data code 112 definitely.In addition, controller 2 (the first control part 25) in the half-wave of alternating voltage 51, the waveform of controller 2 has just started and control signal setting regions has just terminated five half-waves, do not form breach 53.When being " 0 " continuously more than five bits (bit) of the value of digital signal, the control part 75 of ligthing paraphernalia 3 is transitioned into standby mode.When the value of digital signal is formed as " 1 ", the second control part 75 being transitioned into standby mode is judged as that control signal setting regions starts.That is, more than five bits be the beginning that " 0 " refers to control signal setting regions continuously.

Figure 13 (a) shows an example of the control signal 121a being sent to the first constant-current circuit 330a, and Figure 13 (b) shows an example of the control signal 121b being sent to the second constant-current circuit 330b.As shown in Figure 13 (a) and Figure 13 (b), control signal 121a, 121b be, pulse duration is based on the pattern of breach 53 and controlled pulse voltage.In the example shown in Figure 13 (a) and Figure 13 (b), when moment t1, the pulse duration of control signal 121a, 121b changes.By the change of this pulse duration, the light quantity of the light produced from a lamp load 340 and to be photochromicly adjusted to, indicates corresponding light quantity and photochromic with the change inputted via input part 23.

Specifically, by control signal 121a, 121b, control the ratio flowing into the electric current of assorted LED341, regulate the photochromic of the light (mixed light) produced from a lamp load 340 thus.In addition, by control signal 121a, 121b, control the aggregate value flowing into the electric current of assorted LED341, regulate the light quantity of the light (mixed light) produced from a lamp load 340 thus.That is, signal generating unit 32 controls flow into the ratio of the electric current of dual-colored LED 341 and flow into the aggregate value of electric current of dual-colored LED 341, carries out the control of light modulation toning thus.In this wise, signal generating unit 32 controls separately the electric power being supplied to assorted LED341, by the light quantity of the light produced from a lamp load 340 and the photochromic light quantity corresponding with the pattern of breach 53 and photochromic changed into.

In addition, when controller 2 starts, controller 2 (the first control part 25) uses the light quantity and photochromic information that are stored in storage part 25a to set the pattern of breach 53.Further, at least five continuous print half-waves of alternating voltage 51 are cut-off, by after switch portion 21, the action of controller 2 pairs of switch portion 21 controls, the pattern of the breach 53 waveform of alternating voltage 51 being had set.The light quantity that will use when controller 2 starts and the photochromic information content both can be settings, also can be the values that user is stored in storage part 25a.

In addition, also can store the light quantity corresponding to the moment and photochromic information in storage part 25a, and when start-up connector 2, controller 2 can use the light quantity corresponding with current time and photochromic information to set the pattern of breach 53.Thereby, it is possible to produce the light quantity corresponding with the moment and photochromic light.Further, controller 2 can also, in the lighting process of ligthing paraphernalia 3, use the light quantity corresponding with current time and photochromic information to set the pattern of breach 53.Thereby, it is possible to automatically change light quantity and photochromic according to the change in moment.

According to above the present embodiment, for setting the light quantity of the light produced from a lamp load 340 and photochromic signal, transmit to ligthing paraphernalia 3 from controller 2 via power line 4a, 4b.Therefore, do not need to lay special holding wire and can carry out light modulation toning control.

Further, according to the present embodiment, can also the generation of restraint speckle.Such as, in phase dimming mode, on the sinusoidal summit of alternating voltage, bidirectional thyristor has the situation of conducting (ON), now there is the problem producing very large noise (electromagnetic wave).To this, according to the present embodiment, in the half-wave of alternating voltage 51, in the scope of the zero crossing 52 from this half-wave to the position of the phase angle 90 degree of this half-wave not enough, bidirectional thyristor 6 conducting (turnon).Thus, very large noise can not be produced as phase dimming mode.In addition, preferably, the zero crossing 52 the half-wave from alternating voltage 51 in the scope of 2.5m second, by making bidirectional thyristor 6 conducting (turnon), can occur by restraint speckle further, and the loss of the electric power being sent to ligthing paraphernalia 3 can be suppressed.

In addition, according to the present embodiment, the waveform of alternating voltage 51 only has the pattern of breach 53, the region beyond control signal setting regions in control signal setting regions, alternating voltage 51 is continually by switch portion 21.Thereby, it is possible to suppress the loss being sent to the electric power of ligthing paraphernalia 3.

In addition, switch portion 21 also can control the conducting of alternating voltage 51, makes the waveform of alternating voltage 51 repeat to have the pattern of breach 53 at certain time intervals.Accordingly, can suppress the second control part 75 that the possibility of read error occurs.The recurrence interval of the pattern of breach 53 is not limited to fixed time interval, also can be the time interval of variation.

In addition, the first L level 83a corresponded to generation and be formed as " 0 ", be formed as the situation of the digital signal of " 1 " corresponding to the second L level 83b and be illustrated.Generate and correspond to the first L level 83a and be formed as " 1 ", be formed as the digital signal of " 0 " corresponding to the second L level 83b and also can.

In addition, the bit number of light quantity numeric data code 111 and photochromic numeric data code 112 is six bits, but if the light quantity and photochromic all level that can set at ligthing paraphernalia 3 can be represented, just the bit number of light quantity numeric data code 111 and photochromic numeric data code 112 is not particularly limited to.But because bit number is fewer, the amount of power that can allow to be sent to ligthing paraphernalia 3 is more, therefore, it is possible to effectively apply flexibly the electric power supplied from source power supply 5.In addition, bit number is fewer, more can improve the transmission speed transmitting light quantity and photochromic information to ligthing paraphernalia 3.

In addition, when being " 0 " continuously more than five bits of the value of digital signal, the second control part 75 transits to standby mode, but it is " 0 " continuously that the value making the second control part 75 transit to the digital signal of standby mode is not limited to more than five bits.Such as, in order to the beginning in forecasting controlling signal sets region, the breach 53 of specific pattern can be formed at alternating voltage 51.

In addition, for the breach 53 making the waveform of alternating voltage 51 have multiple first pattern continuously, after the conducting controlling alternating voltage 51, the conducting of alternating voltage 51 is controlled, the waveform of alternating voltage 51 is made to have the breach 53 of multiple second pattern continuously, but switch portion 21 also can form the breach 53 of first pattern and the breach 53 of second pattern at the waveform of alternating voltage 51 respectively.

Referring to Figure 14 and Figure 15, other examples drive division 22 of controller 2 being generated to drive singal 61 are described.As shown in Figure 14 (a) and Figure 14 (b), front wheel driving signal 61 is when the zero crossing 52 that the half-wave of alternating voltage 51 terminates declines, and the part terminated at alternating voltage 51 half-wave produces beyond thought breach 54 sometimes.Breach 54 is, sharply to reduce and bidirectional thyristor 6 is automatically shut down produce because of electric power in the part that the half-wave of alternating voltage 51 terminates.

If produce breach 54, as shown in Figure 14 (c), then the 3rd L level 83c can be produced at the pulse signal 83 being sent to the second control part 75 (control part of ligthing paraphernalia 3).Because the 3rd L level 83c is wider than the width of the first L level 83a, therefore exist: the second control part 75 generates the value corresponding to the 3rd L level 83c (breach 54) and is formed as the possibility of the digital signal of " 1 ".

Therefore, as shown in Figure 15 (a) and Figure 15 (b), first control part 25 (control part of controller 2) controls drive division 22, make during switch portion 21 makes alternating voltage 51 continue through, till before object half-wave in the half-wave forming alternating voltage 51, that form breach 53, continue to generate drive singal 61.If like this, as shown in Figure 15 (a), then can not form breach 54 at alternating voltage 51, therefore as shown in Figure 15 (c), the 3rd L level 83c can not be produced.Thus, can suppress the second control part 75 that the worry of read error occurs.

Below other structures of ligthing paraphernalia 3 are described.Figure 16 shows other structures of ligthing paraphernalia 3.As shown in figure 16, ligthing paraphernalia 3 can also possess: the alternating voltage 51 before subtend lighting power feeding section 31 (rectification circuit 310) supply carries out the rectification circuit 33 of rectification.In this case, different from the ligthing paraphernalia 3 shown in Fig. 1, the voltage be rectified after circuit 33 rectification supplies to signal generating unit 32.Therefore, the pattern of the breach 53 that signal generating unit 32 has based on the voltage waveform after being rectified circuit 33 rectification, generates control signal 121a, 121b.As shown in figure 16, rectification circuit 33 can possess the diode 161,162 be connected with power line 4a, 4b respectively.According to such structure, signal generating unit 32 can detect breach 53 more definitely.

Below other structures of signal generating unit 32 are described.Figure 17 represents other structures of signal generating unit 32.As shown in Figure 17 (a), inverting circuit (invertingcircuit) 76 can be set at the back segment of waveform transformation circuit 70.As shown in Figure 17 (b), inverting circuit 76 can possess bipolar transistor 77 and resistor 78.In this case, pulse signal 83 is to the base-transport of bipolar transistor 77, and the collector electrode of the pulse signal 83 after reversion from bipolar transistor 77 and the tie point of resistance 78, transfer to the second control part 75.In addition, resistance 78 is pull-up resistor.Below, be denoted as being squeezed the pulse signal 83 that circuit 76 reverses " inversion pulse signal 84 ".

Inversion pulse signal 84 and threshold value compare by the second control part 75, judge the width of H level.Further, the second control part 75, based on the width of H level, judges that this H level is the H level after making the first L level 83a reversion, still makes the H level after the second L level 83b reversion.Further, the second control part 75 generates and is formed as " 0 " corresponding to the H level and being worth after making the first L level 83a be inverted, is worth corresponding to the H level after making the second L level 83b be inverted the digital signal being formed as " 1 ".

Figure 18 (a) shows an example of the pulse signal 83 under usual state.As shown in Figure 18 (a), usually, the width W 1 of the first L level 83a and the width W 2 of the second L level 83b are fixing.On the other hand, as shown in the double dot dash line of Figure 18 (b), Yin Wendu rises and makes the decline generation passivation of pulse signal 83, the situation that the width of the width W 1 and the second L level 83b that there will be the first L level 83a thus changes.If the pulse signal 83 changed by waveform is sent to the second control part 75, then because of the relation with threshold value, the width of the L level detected by the second control part 75 can change.

Figure 18 (c) shows an example of inversion pulses signal 84.As shown in Figure 18 (b) and Figure 18 (c), if the decline generation passivation of pulse signal 83, then the rising generation passivation of inversion pulses signal 84.But even if the inversion pulses signal 84 changed by waveform is sent to the second control part 75, because of the relation with threshold value, the width of the L level detected by the second control part 75 is also roughly fixing or fixed value.

Therefore, by arranging inverting circuit 76, even if Yin Wendu rises and makes the waveform of pulse signal 83 change, the second control part 75, also without the need to obtaining the width ratio of the H level that inversion pulses signal 84 comprises, namely can read the pattern of breach 53.

(embodiment 2)

Below, with reference to Figure 19-Figure 21, embodiment of the present invention 2 is described.Figure 19 represents the schematic structure of the illuminator 1 in embodiment 2.As shown in figure 19, embodiment 2 illuminator 1 possess on this aspect of multiple ligthing paraphernalia 3a different from embodiment 1.

Figure 20 is the block diagram of the major part of the ligthing paraphernalia 3a representing embodiment 2.Ligthing paraphernalia 3a possess on this aspect of lead-out terminal 35a, 35b different from the ligthing paraphernalia 3 of embodiment 1.Lead-out terminal 35a, 35b are electrically connected with input terminal 34a, 34b via distribution 42a, 42b.

Input terminal 34a, 34b are electrically connected with lead-out terminal 35a, 35b of the lead-out terminal of the controller 2 of leading portion or the ligthing paraphernalia 3a of leading portion via feed line 41a, 41b.One in the lead-out terminal of controller 2 is connected with power line 4a via switch portion 21, and another in the lead-out terminal of controller 2 is connected with power line 4b (with reference to Fig. 1).

Therefore, in the illuminator 1 shown in Figure 19, each ligthing paraphernalia 3a is connected in parallel with power line 4a, 4b via controller 2, for setting light quantity and the photochromic signal (there is the waveform of the alternating voltage 51 of the pattern of breach 53) of the light produced from each ligthing paraphernalia 3, be sent to each ligthing paraphernalia 3 from controller 2 in the lump via feed line 41a, 41b.

As mentioned above, according to the present embodiment, without the need to laying holding wire for controlling, and by a controller 2, the light quantity of the light produced from multiple ligthing paraphernalia 3a and photochromic can be controlled in the lump.

In addition, as shown in figure 21, also intrinsic address (receiver address) can be set respectively at each ligthing paraphernalia 3a.Address, such as, can be set by the dual-in-line switch (DIPswitch) being arranged on each ligthing paraphernalia 3a.In this case, controller 2 makes the pattern of breach 53 be contained in the pattern of breach 53, and the pattern of described breach 53 is for representing the address of the ligthing paraphernalia 3a of control object.When the pattern of breach 53 comprises the pattern for representing the address identical with the address of oneself, each signal generating unit 32 of multiple ligthing paraphernalia 3a, based on the pattern of this breach 53, generates control signal 121a, 121b.By setting intrinsic address respectively at each ligthing paraphernalia 3a like this, the light quantity of the light produced from each ligthing paraphernalia 3a and photochromic can be controlled separately.

(embodiment 3)

Below, with reference to Figure 22, Figure 23 and Figure 24, embodiment of the present invention 3 is described.Embodiment 3 does not possess on this aspect of display part 24 different from other embodiments at controller 2a.

Figure 22 represents the schematic structure of the illuminator 1 of embodiment 3.As shown in figure 22, identical with embodiment 2, illuminator 1 possesses multiple ligthing paraphernalia 3a.Figure 23 is the outside drawing of the controller 2a of embodiment 3.

As shown in figure 23, controller 2a possesses a framework 200 by switchbox (switchbox) type.Framework 200 be provided with as input part 23, light quantity raise button 201, light quantity reduce button 202, photochromic raise button 203, photochromic reduction button 204, complete bright button 205 and power switch button 206.
