Rectification circuit 310 rectifies the alternating voltage 51 come via the transmission of switch portion 21.Rectification circuit 310 is suitably Full-wave rectifying circuit.In the present embodiment, rectification circuit 310 is full-wave rectifying circuit.Smooth circuit 320 is for making rectified current The output smoothing on road 310.An example of smooth circuit 320 is shown in Fig. 5.As shown in figure 5, smooth circuit 320 can also be by two Pole pipe 321 and electrolytic capacitor 322 are constituted.
Return to Fig. 1, via switch portion 21 transmission come alternating voltage 51, by rectification circuit 310 and smooth circuit 320 come Be converted to DC voltage.Each constant-current circuit 330 generates constant electricity according to the output (DC voltage) of smooth circuit 320 respectively Stream.By this constant current, supplied electric power to lamp load 340 (LED341).
Fig. 6 is the figure for showing a part of 330 an example of constant-current circuit, indicates the periphery electricity of point lamp load 340 (LED341) The structure on road.As shown in fig. 6, constant-current circuit 330 can include: three resistors 331,332,333；NchMOSFET334；Coil 335；Diode 336；Iron-core coil 337；And electrolytic capacitor 338.Electrolytic capacitor 338 is filled by the output of smooth circuit 320 Electricity.According to the signal from signal generation portion 32, NchMOSFET 334 repeats that (turn on) is connected and turns off, as a result, Electrolytic capacitor 338 repeats to be charged and discharged.Constant current flows into LED341 as a result, so that LED341 shines.
The light quantity of light generated from lamp load 340 and photochromic is adjusted, is by the constant of control inflow colors LED341 The current value of electric current is realized.Therefore, signal generation portion 32 generate as control signal, for controlling NchMOSFET 334 conducting (on) time and the signal of shutdown (off) time.
Fig. 7 is the figure for showing an example of signal generation portion 32, and Fig. 8 shows each portion of signal generation portion 32 shown in Fig. 7 It is mitogenetic at signal waveform.The case where controlling NchMOSFET334 (an example of switch element) turn-on time and turn-off time Under, signal generation portion 32 is also possible to circuit structure as shown in Figure 7.Signal generation portion 32 shown in Fig. 7 has waveform convertion Circuit 70 and the second control unit 75.In addition, as shown in fig. 7, to 75 supply line voltage Vcc of the second control unit.Power source voltage Vcc It is generated by power circuit is (not shown), the power circuit is identical as controller 2, is arranged in luminaire 3.
Waveform convertion circuit 70, by the way that the output (voltage after rectification) of rectification circuit 310 to be compared to threshold value Generate pulse signal.Waveform convertion circuit 70 can have three resistance 71,72,73 and bipolar junction transistor 74.Resistance 71,72 structures At the bleeder circuit for being divided to rectified voltage.The output voltage of the bleeder circuit is applied to bipolar junction transistor 74 Base stage (base).
Fig. 8 (a) shows the wave for being applied to the voltage 81 (output voltage of bleeder circuit) of 74 base stage of bipolar junction transistor An example of shape.The output voltage 81 of bleeder circuit includes notch 53.Threshold value and partial pressure of the bipolar junction transistor 74 according to its base stage Size relation between the output voltage 81 of circuit repeats that (turn on) is connected and turns off.As a result, in bipolar transistor On the collector (collector) of pipe 74 and the tie point of resistance 73, pulse signal 83 as shown in Fig. 8 (b) are generated.Fig. 8 (b) Show 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 position 82 corresponding with the zero crossing 52 of alternating voltage 51, partial pressure The output voltage 81 of circuit is lower than base stage threshold value, and pulse signal 83 is L level (level).Specifically, pulse signal 83 includes Two kinds of L levels, described two L levels have width corresponding with the presence or absence of notch 53.This is because, forming jagged 53 The output voltage 81 of place, bleeder circuit becomes longer compared with being not formed in place of notch 53 lower than the time of base stage threshold value. That is, generating the first L level 83a with the first width 53 place of notch is not formed, jagged 53 place is being formed, is being produced The raw second L level 83b with the second width for being longer than the first width.Pulse signal 83 generated in this way is transmitted to the second control Portion 75 processed.
Second control unit 75 is, for example, microcomputer.Voltage is from the collector of bipolar junction transistor 74 and the company of resistance 73 Contact is applied to the second control unit 75.That is, pulse signal 83 is transmitted to the second control unit 75.Second control unit 75 is according to pulse Two kinds of L levels (the first L level 83a and the second L level 83b) that signal 83 is included and generate digital signal.
Specifically, pulse signal 83 is compared by the second control unit 75 with threshold value, judges the width of L level.Also, Second width of the control unit 75 based on L level judges that the L level is the first L level 83a or the second L level 83b, thus raw It is worth at the first L level 83a is corresponded to and is formed as " 0 ", is worth the digital signal for being formed as " 1 " corresponding to the second L level 83b. That is, by the conducting for controlling alternating voltage 51 by controller 2 (switch portion 21), so that the friendship that control signal setting regions is included The all or part of waveform of the half-wave of galvanic electricity pressure 51 has notch 53, thus the data phase with bit (bit) size When signal with the half-wave unit transmission of alternating voltage 51 to luminaire 3.Here, the second control unit 75, such as every number 100 Pulse signal 83 was compared in μ seconds with threshold value, thus judges the width of the L level of pulse signal 83.In this wise, by by arteries and veins It rushes signal 83 to be meticulously compared with threshold value, is able to suppress the influence for the noise that pulse signal 83 is included.
Preferably, until before detecting the second L level 83b, the second control unit 75 finds out time upper adjacent L level Width ratio, and judge 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, Ratio compared with the width of a L level on the time before it.Specifically, when the width ratio of the L level found out When for value in defined first range, the second control unit 75 judges the L level for the first L level 83a.On the other hand, when asking When the width ratio of L level out is the value in defined second range, the second control unit 75 judges the L level for the 2nd L electricity Flat 83b.First range is set as being narrower than the second range.Also, after detecting the second L level 83b, and detecting the first L electricity Until before flat 83a, the second control unit 75 finds out the width ratio as L level, the second L level 83b relative to previous L electricity The ratio of the width of flat (the first L level 83a).In addition, when the value of the L level width ratio found out is " 1 ", the second control unit 75 Judge that the L level can also for the first L level 83a.
When finding out L level width ratio in this way, it is preferable that controller 2 is after power supply connection not immediately in alternating voltage 51 waveform formation notch 53, but the first L level 83a is repeatedly continuously generated on pulse signal 83.In addition, being controlled at one After signal setting regions processed, controller 2 does not form notch 53 on the waveform of alternating voltage 51, but in pulse signal 83 On be repeatedly continuously generated the first L level 83a.
By finding out the width ratio of L level as described above, even if the width of L level becomes caused by rising because of temperature Change, the second control unit 75 can also read pulse signal 83 (pattern of notch 53).Fig. 9 (a) is shown under usual state An example of the waveform of pulse signal 83.As shown in Fig. 9 (a), in general, the width W1 of the first L level 83a and the second L level 83b Width W2 is fixed.On the other hand, as shown in the double dot dash line of Fig. 9 (b), make the decline of pulse signal 83 because temperature rises It is passivated, thus will appear the case where width of the width W1 and the second L level 83b of the first L level 83a changes.Cause This, the width W2 of the width W1 and the second L level 83b of the first L level 83a judged by the second control unit 75 is respectively and solid Definite value is compared, and then judges that L level is the first L level 83a or the second L level 83b, in this case, if because of temperature Degree rises and the waveform widths of pulse signal 83 is made to change, then there is the second control unit 75 can not read pulse signal 83 Possibility.In this regard, the variation of each L level width is also even if being passivated the decline of pulse signal 83 because temperature rises Therefore roughly the same degree by finding out the width ratio of L level, can read pulse signal 83.
If generating digital signal, content (data) of the second control unit 75 meeting based on the digital signal generates use respectively Each NchMOSFET334 of each constant-current circuit 330 (the first constant-current circuit 330a and the second constant-current circuit 330b) is contained in control Turn-on time and the signal of turn-off time (control signal).Specifically, control signal is pulse voltage, and according to number The content of signal determines the pulse width to each constant-current circuit 330a, 330b pulse voltage transmitted.Therefore, it flows into and is contained in The current value of the constant current of the LED341 of each constant-current circuit 330a, 330b, for the value of the content corresponding to digital signal, i.e. shape Value as the pattern for corresponding to notch 53.The setting of pulse width about pulse voltage, such as by the second control unit 75 storage unit 75a storage inspection table can also to realize.
Then ,-Figure 13 referring to Fig.1, light quantity to lamp load 340 and it is photochromic at least one change when, illumination system The movement of system 1 is illustrated.Figure 10-Figure 12 indicates the signal waveform of each section of lighting system 1.
Sinuous alternating voltage 51 shown in Figure 10 (a) is supplied from source power supply 5 to power line 4a, 4b.If changed Become from the light quantity of the light that lamp load 340 generates and it is photochromic at least one instruction inputted via input unit 23, then first control Portion 25 processed is according to the movement for changing indicating control switch portion 21.Switch portion 21 controls the conducting of alternating voltage 51 as a result, So that the waveform of alternating voltage 51 has the pattern of the notch 53 set in control signal setting regions.In addition, the first control Portion 25 controls the movement of switch portion 21, so that alternating voltage 51 continuously leads in the region controlled other than signal setting regions Cross switch portion 21.
In the present embodiment, switch portion 21 controls the conducting of alternating voltage 51, so that the pattern packet of notch 53 It includes the first pattern for indicating light quantity and indicates the second photochromic pattern.Specifically, conducting of the switch portion 21 to alternating voltage 51 It is controlled, so that the waveform of alternating voltage 51 continuously has the notch 53 of multiple first patterns, later, to alternating voltage 51 Conducting controlled so that the waveform of alternating voltage 51 continuously has the notch 53 of multiple second patterns.Here, to exchange The waveform of voltage 51 after the first pattern is continuously cut away twice, said by the case where the second pattern is continuously cut away twice It is bright.
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 21 temporarily disconnected alternating voltage 51 of portion, thus in the waveform formation notch 53 of alternating voltage 51.Later, with the exchange of notch 53 Voltage 51 is sent to the rectification circuit 310 of luminaire 3.
Rectification circuit 310 rectifies the alternating voltage 51 come via the transmission of switch portion 21.Figure 10 (c) shows rectification An example of the output (voltage 81 after rectification) of circuit 310.Smooth circuit 320 makes output smoothenedization of rectification circuit 310. Figure 10 (d) shows an example of the output of smooth circuit 320.As shown in Figure 10 (d), it can be obtained directly by smooth circuit 320 Galvanic electricity pressure 101.Therefore, DC voltage 101 is supplied from smooth circuit 320 to each constant-current circuit 330.
On the other hand, the voltage 81 after being rectified by rectification circuit 310 is sent to signal generation portion 32.Signal generation portion 32 patterns based on notch 53 possessed by voltage 81 carry out the change of control signal to each colors LED341.In this implementation In scheme, waveform convertion circuit 70 generates pulse signal 83 corresponding with the pattern of notch 53 (referring to Fig. 8).Also, the second control Portion 75 processed generates number letter according to the two kinds of L levels (the first L level 83a and the second L level 83b) for being contained in pulse signal 83 Number.Specifically, as shown in figure 11, the second control unit 75 generates the first number corresponding with the notch 53 of the first pattern twice in succession Word signal (light quantity numeric data code (data code) 111) then generates and the notch 53 corresponding second of the second pattern twice in succession Digital signal (photochromic numeric data code 112).
Whether the second control unit 75 is identical according to two light quantity numeric data codes 111, judges the light generated from lamp load 340 Whether light quantity adjusts effective.Same, whether the second control unit 75 is identical according to two photochromic numeric data codes 112, judges from point Whether the photochromic adjusting for the light that lamp load 340 generates is effective.Also, the second control unit 75 is adjusted respectively according to light quantity and photochromic tune Section whether effective judging result, generate control signal.
Specifically, when two light quantity numeric data codes 111 are identical and two photochromic numeric data codes 112 are identical, the second control unit 75 are based on light quantity numeric data code 111 and photochromic numeric data code 112, generate the control of the movement for controlling each constant-current circuit 330 respectively Signal (pulse voltage).That is, the second control unit 75 is determined to each constant-current circuit 330 (the first constant-current circuit 330a and the second constant current Circuit 330b) transmission pulse voltage pulse width.Also, then waveform formation notch of the controller 2 in alternating voltage 51 Until before 53, each pulse voltage with the pulse width being determined is respectively sent to corresponding by the second control unit 75 Constant-current circuit 330.The pattern for the notch 53 for being included according to control signal setting regions as a result, is sent to each constant-current circuit 330 Control signal at least one be changed.This control signal be make a lamp load 340 light quantity and it is photochromic respectively with light quantity The signal of numeric data code 111 and the corresponding level of photochromic numeric data code 112.In addition, the second control unit 75 is by light quantity numeric data code 111 and light Color numeric data code 112 is stored in storage unit 75a.
On the other hand, when two light quantity numeric data codes 111 are identical and two photochromic numeric data codes 112 are inconsistent, the second control The light quantity numeric data code 111 that portion 75 is generated based on this and the photochromic numeric data code 112 being stored in storage unit 75a, determine to each perseverance The pulse width for the pulse voltage that current circuit 330 transmits.When two light quantity numeric data codes 111 are inconsistent and two photochromic numeric data codes 112 it is consistent when, also after the same method determine pulse voltage pulse width.In addition, as two light quantity numeric data codes 111 and two When a photochromic numeric data code 112 is inconsistent, the second control unit 75 is not changed control signal.
Figure 12 shows signal generation portion 32 (the second control unit 75) and lacks corresponding to what control signal setting regions was included Mouthfuls 53 pattern and an example of digital signal generated.Figure 12 is the figure for schematically showing digital signal, each light quantity numeric data code 111 and the numerical tabular of each photochromic numeric data code 112 " 0 " and " 1 " for being included show the value of digital signal.As shown in figure 12, in this reality It applies in scheme, bit (bit) number of light quantity numeric data code 111 and photochromic numeric data code 112 is six bits.That is, switch portion 21 is right The conducting of alternating voltage 51 is controlled, so that all or part of wave of continuous 24 half-waves of alternating voltage 51 Shape has notch 53, thus generates light quantity numeric data code 111 and photochromic numeric data code 112 twice respectively in signal generation portion 32.Accordingly, Control signal setting regions is determined according to the quantity of the half-wave of alternating voltage 51.
In addition, respectively foremost value is " 1 " for each light quantity numeric data code 111 and each photochromic numeric data code 112.Second control as a result, Portion 75 processed can definitely detect each light quantity numeric data code 111 and the respective most forefront part of each photochromic numeric data code 112.In addition, Controller 2 (first control units 25) in the half-wave of alternating voltage 51, controller 2 just start and control signal setting regions The waveform of five half-waves just terminated does not form notch 53.Continuously it is more than five bits (bit) of the value of digital signal When " 0 ", the control unit 75 of luminaire 3 is transitioned into standby mode.When the value of digital signal is formed as " 1 ", it is transitioned into standby Second control unit 75 of mode is judged as that control signal setting regions has begun.That is, more than five bits continuously referring to for " 0 " Control the beginning of signal setting regions.
Figure 13 (a) shows an example for being sent to the control signal 121a of the first constant-current circuit 330a, and Figure 13 (b) is shown It is sent to an example of the control signal 121b of the second constant-current circuit 330b.As shown in Figure 13 (a) and Figure 13 (b), signal is controlled 121a, 121b be, pattern of the pulse width based on notch 53 and the pulse voltage that is adjusted.Shown in Figure 13 (a) and Figure 13 (b) An example in, in moment t1, control signal 121a, 121b pulse width change.Pass through the change of this pulse width Change, from lamp load 340 generate light light quantity and it is photochromic be adjusted to, it is corresponding with the change instruction inputted via input unit 23 Light quantity and photochromic.
Specifically, by controlling signal 121a, 121b, control flows into the ratio of the electric current of assorted LED341, thus Adjust the photochromic of the light (light mixing) generated from lamp load 340.In addition, by control signal 121a, 121b, control flows into each Thus the aggregate value of the electric current of color LED341 adjusts the light quantity of the light (light mixing) generated from lamp load 340.That is, signal generates Portion 32 control flow into dual-colored LED 341 electric current ratio and flow into dual-colored LED 341 electric current aggregate value, thus into The control of row light modulation toning.In this wise, individually control supply will be born signal generation portion 32 to the electric power of assorted LED341 from lighting Carry the light quantity and the photochromic light quantity corresponding with the pattern of notch 53 and photochromic changed into of the light that 340 generate.
In addition, controller 2 (first control units 25) uses the light quantity being stored in storage unit 25a when controller 2 starts The pattern of notch 53 is set with photochromic information.Also, it is not cut at least five continuous half-waves of alternating voltage 51 Break by the way that after switch portion 21, controller 2 controls the movement of switch portion 21, is set so that the waveform of alternating voltage 51 has The pattern for the notch 53 set.By light quantity to be used and the photochromic information content either specified value when controller 2 starts, It is also possible to the value that user is stored in storage unit 25a.
Alternatively, it is also possible to store light quantity corresponding with the moment and photochromic information in storage unit 25a, and controlled in starting When device 2 processed, controller 2 will use light quantity corresponding with current time and photochromic information to set the pattern of notch 53.As a result, Light quantity corresponding with the moment and photochromic light can be generated.Further, controller 2 can also be in the lighting of luminaire 3 Cheng Zhong sets the pattern of notch 53 using light quantity corresponding with current time and photochromic information.Thereby, it is possible to according to the moment Variation and change light quantity and photochromic automatically.
According to above the present embodiment, for set the light generated from lamp load 340 light quantity and photochromic signal, It is transmitted via power line 4a, 4b from controller 2 to luminaire 3.Therefore, there is no need to be laid with dedicated signal wire can be adjusted Light toning control.
Further, according to the present embodiment, moreover it is possible to inhibit the generation of noise.For example, being exchanged in phase dimming mode The sinusoidal vertex of voltage, bidirectional thyristor have the case where conducting (ON), exist generate very big noise (electromagnetic wave) at this time The problem of.In this regard, according to the present embodiment, in the half-wave of alternating voltage 51, zero crossing 52 since the half-wave to deficiency In the range of until 90 degree of phase angle of position of the half-wave, (turn on) is connected in bidirectional thyristor 6.To such as phase tune Light mode will not generate very big noise like that.Furthermore it is preferred that the zero crossing 52 the half-wave since alternating voltage 51 passes through It crosses in the range of 2.5m seconds, by making bidirectional thyristor 6 that (turn on) be connected, noise can be further suppressed, and may be used also Inhibit the loss for being sent to the electric power of luminaire 3.
In addition, the waveform of alternating voltage 51 only has notch 53 in control signal setting regions according to the present embodiment Pattern is controlling the region other than signal setting regions, and alternating voltage 51 is continually by switch portion 21.Thereby, it is possible to inhibit It is sent to the loss of the electric power of luminaire 3.
In addition, switch portion 21 can also control the conducting of alternating voltage 51, so that the waveform of alternating voltage 51 exists Certain time interval repeat the pattern with notch 53.Accordingly, it can inhibit the second control unit 75 that the possibility of read error occurs. The recurrence interval of the pattern of notch 53 is not limited to fixed time interval, is also possible to the time interval changed.
In addition, corresponding to the first L level 83a to generation and being formed as " 0 ", be formed as corresponding to the second L level 83b The case where digital signal of " 1 ", is illustrated.It generates and corresponds to the first L level 83a and be formed as " 1 ", correspond to the 2nd L electricity Flat 83b and the digital signal for being formed as " 0 " can also.
In addition, the bit number of light quantity numeric data code 111 and photochromic numeric data code 112 is six bits, but as long as can indicate It can be in the light quantity and photochromic all level that luminaire 3 is set, just to light quantity numeric data code 111 and photochromic numeric data code 112 bit number is not specially limited.But since bit number is fewer, the amount of power for being sent to luminaire 3 can be allowed to It is more, therefore, it can effectively apply flexibly the electric power supplied from source power supply 5.In addition, bit number is fewer, can more improve to illumination The transmission speed of utensil 3 transmission light quantity and photochromic information.
In addition, the second control unit 75 transits to standby mould when being continuously " 0 " more than five bits of the value of digital signal Formula, but it is " 0 " that the value for the digital signal for making the second control unit 75 transit to standby mode, which is not limited to five bits or more continuously,. For example, for the beginning of forecasting controlling signal setting regions, it can be in the notch 53 of the formation specific pattern of alternating voltage 51.
In addition, to make the waveform of alternating voltage 51 that continuously there is the notch 53 of multiple first patterns, in control alternating current Pressure 51 conducting after, the conducting of alternating voltage 51 is controlled so that the waveform of alternating voltage 51 continuously have it is multiple The notch 53 of second pattern, still, switch portion 21 can also be respectively formed first pattern in the waveform of alternating voltage 51 The notch 53 of notch 53 and second pattern.
Referring to Figure 14 and Figure 15, the other examples for generating driving signal 61 to the driving portion 22 of controller 2 are said It is bright.As shown in Figure 14 (a) and Figure 14 (b), preceding driving signal 61 declines in the zero crossing 52 that the half-wave of alternating voltage 51 terminates In the case of, unexpected notch 54 is generated sometimes in the part that 51 half-wave of alternating voltage terminates.Notch 54 is, because electric power exists It sharply reduces and bidirectional thyristor 6 is made to automatically shut down to generate in the part that the half-wave of alternating voltage 51 terminates.
If can then 75 (the control of luminaire 3 of the second control unit be sent to as shown in Figure 14 (c) by generating notch 54 Portion) pulse signal 83 generate third L level 83c.Since third L level 83c is wider than the width of the first L level 83a, deposit : the second control unit 75 generate correspond to third L level 83c (notch 54) and value be formed as the digital signal of " 1 " a possibility that.
Therefore, as shown in Figure 15 (a) and Figure 15 (b), first control units 25 (control unit of controller 2) to driving portion 22 into Row control, so that during switch portion 21 continues through alternating voltage 51, in the half-wave for forming alternating voltage 51, shape Until before the object half-wave of notch 53, continue to generate driving signal 61.If so, then being exchanged as shown in Figure 15 (a) Voltage 51 not will form notch 54, therefore as shown in Figure 15 (c), will not generate third L level 83c.It is thereby possible to suppress the second control The worry of read error occurs for portion 75 processed.
It is illustrated below against the other structures of funerary objects tool 3.Figure 16 shows the other structures of luminaire 3.Such as figure Shown in 16, luminaire 3 can also have: the alternating current before opposite lighting power feeding section 31 (rectification circuit 310) supply The rectification circuit 33 that pressure 51 is rectified.In this case, different from luminaire 3 shown in FIG. 1, it is rectified the rectification of circuit 33 Voltage afterwards is supplied to signal generation portion 32.Therefore, signal generation portion 32 is based on the voltage waveform after being rectified the rectification of circuit 33 The pattern of possessed notch 53 generates control signal 121a, 121b.As shown in figure 16, rectification circuit 33 can have difference The diode 161,162 being connect with power line 4a, 4b.According to this structure, signal generation portion 32 can be examined more definitely Measure notch 53.
The other structures of signal generation portion 32 are illustrated below.The other structures of Figure 17 expression signal generation portion 32. As shown in Figure 17 (a), inverting circuit (inverting circuit) 76 can be set in the back segment of waveform convertion circuit 70.Such as Shown in Figure 17 (b), inverting circuit 76 can have bipolar junction transistor 77 and resistor 78.In this case, pulse signal 83 to The base-transport of bipolar junction transistor 77, pulse signal 83 after reversion is from the collector of bipolar junction transistor 77 and resistance 78 Tie point is transmitted to the second control unit 75.In addition, resistance 78 is pull-up resistor.Hereinafter, the pulse for circuit 76 will be squeezed inverting Signal 83 is denoted as " inversion pulse signal 84 ".
Inversion pulse signal 84 is compared by the second control unit 75 with threshold value, judges the width of H level.Also, second Width of the control unit 75 based on H level judges that the H level is the H level after inverting the first L level 83a, still makes the 2nd L H level after level 83b reversion.Also, the second control unit 75 generate correspond to make the first L level 83a be inverted after H level and Value be formed as " 0 ", corresponding to make the second L level 83b be inverted after H level and be worth the digital signal for being formed as " 1 ".
Figure 18 (a) shows an example of the pulse signal 83 under usual state.As shown in Figure 18 (a), in general, the first L is electric The width W2 of the width W1 of flat 83a and the second L level 83b are fixed.On the other hand, as shown in the double dot dash line of Figure 18 (b), It is passivated the decline of pulse signal 83 because temperature rises, thus will appear the width W1 and the 2nd L of the first L level 83a The case where width of level 83b changes.If the changed pulse signal 83 of waveform is sent to the second control unit 75, Because of the relationship with threshold value, the width of L level detected by the second control unit 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 pulse signal 83 Decline be passivated, then the rising of inversion pulses signal 84 is passivated.But even if by the changed inversion arteries and veins of waveform It rushes signal 84 and is sent to the second control unit 75, because of the relationship with threshold value, the width of L level detected by the second control unit 75 For approximately fixed or fixed value.
Therefore, by the way that inverting circuit 76 is arranged, even if making the waveform of pulse signal 83 change because temperature rises, the The pattern of notch 53 can be read without the width ratio for finding out the H level that inversion pulses signal 84 is included in two control units 75.
