With reference to accompanying drawing, the bull switch of the present embodiment is provided to following explanation.
As shown in fig. 1, the bull switch of the present embodiment comprises the control circuit (control unit) 10 for controlling lighting load L1.In addition, bull switch comprises manual operation circuit (manual operation unit) 2, power supply circuit 16, people's transducer S1 and optical sensor S2.In addition, as shown in Figures 3 and 4, bull switch comprises: for holding main body 3, trim 4 and the lid 5 of circuit block (control unit 10, manual operation unit 2, power supply circuit 16, people's transducer S1 and optical sensor S2).
User uses manual operation unit 2 with operation bull switch.Manual operation unit 2 comprises mode setting unit 20, ventilation fan interlock setting unit 21, time of delay setting unit 22, duration setting unit 23, illumination section setting unit continuous time 24, optical sensor setting unit 25, illumination setting unit 26 and lower limit illumination setting unit 27.
As mentioned above, the Lighting Control Assembly of the present embodiment comprises, as shown in fig. 1, and control unit 10, power subsystem 11, filter cell 12, zero passage detection unit 13, relay drive unit 14, display unit 15 and manual operation unit 2.In addition, the bull switch of the present embodiment comprises splicing ear T1 to T3, full-wave rectifier DB1, three terminal bidirectional alternating-current switch TR1, thyristor SCR1, relay R E1 and fuse FU1.
Be connected between splicing ear T1 and T2 by commercial ac power source AC1 and such as the series circuit of the lighting load L1 of LED lamp etc.Splicing ear T1 is connected with the AC input terminal of full-wave rectifier DB1 separately with T2.The series circuit of commercial ac power source AC1 and ventilation fan F1 is connected between splicing ear T1 and T3.Fuse FU1 is connected between splicing ear T1 and filter cell 12 and avoids rated value or larger large electric current with protective circuit.
Full-wave rectifier DB1 comprises diode bridge.Full-wave rectifier DB1 is to carrying out full-wave rectification by the alternating voltage of splicing ear T1 and T2 input, and output dc voltage (pulse current voltage).Two main terminals of three terminal bidirectional alternating-current switch TR1 are connected with the AC input terminal of full-wave rectifier DB1 respectively.The parallel circuits of resistor R1 and capacitor C1 is connected between the gate terminal and a main terminal of three terminal bidirectional alternating-current switch TR1.The series circuit of resistor R3 and thyristor SCR1 is connected between DC output end of full-wave rectifier DB1.The parallel circuits of resistor R2 and capacitor C2 is connected between the grid and negative electrode of thyristor SCR1.
Realize control unit 10 by using for example microcomputer.Control unit 10 is based on carry out the illumination control to lighting load L1 and the operation control to ventilation fan F1 from the signal of manual operation unit 2, people's transducer S1 and optical sensor S2.Control unit 10 is connected with optical sensor S2 with people's transducer S1.People's transducer S1 is designed to judge in surveyed area, whether have people.Optical sensor S2 is designed to measure the light in surveyed area inside.
People's transducer S1 is for example thermoelectric pickup.People's transducer S1 is designed to detect from the infrared ray of the object institute radiation of such as human body etc. by detection people's existence.In the situation that people being detected, detection signal is sent to control unit 10 by people's transducer S1.
Optical sensor S2 is for example photoelectric crystal triode or photodiode.Optical sensor S2 measures light around and the signal with the level corresponding with light intensity is sent to control unit 10.
In the present embodiment, people's transducer S1 and optical sensor S2 are built in main body 3.But transducer S1 and S2 can be arranged on respectively main body 3 outsides.In this case, the signal of transducer S1 and S2 can be sent to control unit 10 with wire communication or radio communication.
Zero passage detection unit 13, by the pulse current voltage being obtained by the full-wave rectification of full-wave rectifier DB1 is compared with predetermined threshold, detects the zero passage of commercial ac power source AC1.At pulse current voltage drop, to below predetermined threshold in the situation that, zero passage detection unit 13 will have low level binary signal and export control unit 10 to.In the situation that pulse current voltage exceedes predetermined threshold, zero passage detection unit 13 exports the binary signal with high level to control unit 10.
Relay R E1 comprises for example relay contact and magnet exciting coil (not shown).Relay contact is connected with ventilation fan F1 series connection.
Following explanation is carried out in illumination control to lighting load L1 in the present embodiment.
Change to from low level at the level of the binary signal of exporting from zero passage detection unit 13 moment of high level after stand-by period section Tw (seeing Fig. 9 and Figure 10), control unit 10 is the gate terminal to thyristor SCR1 by drive voltage supply.Now, thyristor SCR1 conducting and therefore driving voltage be also supplied to the gate terminal of three terminal bidirectional alternating-current switch TR1 and therefore three terminal bidirectional alternating-current switch TR1 conducting.Therefore, alternating voltage is supplied to lighting load L1 from commercial ac power source AC1, and lighting load L1 opens.Subsequently, in the case of the next zero passage of the alternating voltage from commercial ac power source AC1 arrives, three terminal bidirectional alternating-current switch TR1 and thyristor SCR1 cut-off and the therefore supply of the alternating voltage to lighting load L1 stop.
In other words the angle of flow (ON time section) Tc (seeing Fig. 9 and Figure 10) that, control unit 10 is supplied to the alternating voltage of lighting load L1 by control adjusts the electric power that is supplied to lighting load L1 to operate lighting load L1 in desired dimming level.As mentioned above, control unit 10 is for controlling power supply circuit 16 to supply with the electric power corresponding with dimming level to lighting load L1.Dimming level is corresponding with the illumination of lighting load L1.
The control unit 10 storage tables of data (see Fig. 7) relevant to the dimming level of lighting load L1.
This tables of data records the data set of dimming level and the stand-by period section Tw that dimming level is associated therewith for each supply frequency (50Hz and 60Hz) of commercial ac power source AC1.
Stand-by period section Tw has defined the moment that the binary signal exported from zero passage detection unit 13 switches to high level from low level and has started the time period finishing to the moment of three terminal bidirectional alternating-current switch TR1 conducting.As shown in Fig. 9 and Figure 10, the reducing of stand-by period section Tw cause the increase of the angle of flow (ON time section) Tc and therefore the light output (illumination) of lighting load L1 increase.On the contrary, the increase of stand-by period section Tw cause reducing of the angle of flow (ON time section) Tc and therefore the light output (illumination) of lighting load L1 reduce.
Generally speaking, dimming level increases along with reducing of stand-by period section Tw and dimming level reduces along with the increase of stand-by period section Tw.
In the present embodiment, the light output (illumination) of lighting load L1 is categorized as to dimming level 0 to 127.For example, dimming level 0 represents that lighting load L1 closes, and dimming level 127 represents to light lighting load L1 with highest luminance level (, illumination is output as 100%).The illumination that will be lighting load L1 in the situation of maximum (in the present embodiment, 127) in dimming level in the present embodiment, is defined as maximal illumination.The illumination that will be lighting load L1 in the situation of minimum value (in the present embodiment, 0) in dimming level on the contrary, is defined as minimal illumination.In the present embodiment, in the situation that dimming level is 0, lighting load L1 extinguishes.Therefore, minimal illumination is 0 (maximal illumination 0%).
It is below the cutline of the structure of the bull switch to the present embodiment made from reference to figure 3 and Fig. 4.In the following description, unless otherwise indicated, otherwise defined upper and lower, the front and rear direction of the bull switch of the present embodiment by each arrow shown in Fig. 3.
As shown in Figure 3, the bull switch of the present embodiment comprises main body 3, is mounted to main body 3 to make main body covered 3 positive trim 4 and lid 5.
It is removable to make between the position of the position that exposes the manual operation unit 2 except illumination setting unit 26 (lower limit illumination setting unit 27) and covering manual operation unit 2 that lid 5 is mounted to trim 4.For example rectangular plate shape is made and be formed as to lid 5 by synthetic resin.
As shown in Figures 4 and 5, trim 4 is provided with to 2 square holes 40 that are respectively used to by the first slide switch 200 of module setting unit 20 and the second slide switch 210 of ventilation fan interlock setting unit 21.In addition, trim 4 is provided with to 4 circular holes 41 of the second knob 230, the 3rd knob 240 of illumination section setting unit continuous time 24 and the 4th knob 250 of optical sensor setting unit 25 that are respectively used to by time of delay setting unit the first knob 220 of 22, duration setting unit 23.
Therefore, even if make the user also can manual operation slide switch 200 in the situation that trim 4 has been installed and 210 and knob 220 to 250.
As shown in Figure 6, the first push-button switch B1 and the second push-button switch B2 of illumination setting unit 26 (lower limit illumination setting unit 27) are exposed on the front of main body 3.The first push-button switch B1 and the second push-button switch B2 are configured for receiving the member (control member) from user's manual input.In other words, main body 3 is held illumination setting unit 26 (lower limit illumination setting unit 27) to make to expose control member.
Hide each push-button switch B1 and B2 (, for receiving the member of manual input) with trim 4.But, in the situation that having dismantled trim 4, can operate each push-button switch B1 and B2.In brief, trim 4 is mounted to main body 3 removably to hide the control member being exposed in main body 3.
Therefore,, because user does not generally recognize illumination setting unit 26 (lower limit illumination setting unit 27), therefore can avoid inadvertently selecting the misoperation for the dimming level within the light modulation time period of lighting load L1.
The unit that manual operating unit 2 is comprised carries out following explanation.As shown in fig. 1, manual operation unit 2 comprises mode setting unit 20, ventilation fan interlock setting unit 21, time of delay setting unit 22, duration setting unit 23, illumination section setting unit continuous time 24, optical sensor setting unit 25, illumination setting unit 26 and lower limit illumination setting unit 27.
Ventilation fan interlock setting unit 21 comprises the second slide switch 210 as shown in Figure 5.Ventilation fan interlock setting unit 21 is for judging whether ventilation fan F1 operates in the situation that people's transducer S1 detects people.
Whether detect that based on people's transducer S1 people can judge whether that existing people enters or left room.For example, control unit 10 detects that in the case of people's transducer S1 of people not yet being detected people, being judged to be existing people enters room, and control unit 10 does not detect that in the case of people's transducer S1 of people being detected people, being judged to be existing people withdraws from a room.
Setting unit 22 comprised rotary switch (not shown) and was mounted to the first knob 220 (seeing Fig. 5) of the operating axis of rotary switch time of delay.Time of delay, setting unit 22 was for determining the time of delay that is limited to the time period between the moment that the illumination moment that section Th finishes continuous time and ventilation fan F1 close.
In addition, time of delay, setting unit 22 can be according to the position of rotation of the first knob 220, selected to force to keep the operation that ventilation fan F1 closes or the operation that keeps continuously ventilation fan F1 to open.
Therefore, by selecting time of delay setting unit 22 to force the operation that keeps ventilation fan F1 to close, can be in the case of user to not having ventilation fan F1 in the bathroom of window to carry out clean only opening lighting load L1 in being arranged on apartment.In addition, by selecting the operation that time of delay, setting unit 22 pressures kept ventilation fan F1 to open, can a direct-open ventilation fan F1.
In the present embodiment, can, according to the position of rotation of the second knob 230, the scope of from 4 to 8 hours, select the duration of light modulation time period with the step-length of 1 hour.Until the position of rotation of the second knob 230 changes, control unit starts the control that lighting load L1 is dimmed 10 every days in the situation that the light modulation time period starts, and through the selected duration in the situation that, starts normal control.
Illumination section setting unit continuous time 24 comprises rotary switch (not shown) and is mounted to the 3rd knob 240 (seeing Fig. 5) of the operating axis of rotary switch.Illumination section setting unit continuous time 24 is for determining illumination section continuous time (operation section continuous time) Th.
Illumination section Th continuous time is defined as to the time period (seeing Fig. 2) finishing since moment T2 and at moment T3.Moment T2 is the moment that people's transducer S1 does not detect people's (, people's transducer S1 judge as people do not exist).Moment T3 lights the moment that operation back lighting load L1 closes closing pre-notice.The object of the lighting load L1 that will close for pre-notice, closes pre-notice and lights operation by dimming lighting load L1.
Optical sensor setting unit 25 comprises rotating type adjustable resistor (not shown) and is mounted to the 4th knob 250 (seeing Fig. 5) of the operating axis of variable resistance.Optical sensor setting unit 25 is for determining the threshold value of optical sensor S2.Threshold value is for judging the whether detection to people and to the lighting load L1 control of throwing light in response to people's transducer S1 of control unit 10.The resistance value of variable resistance changes along with the rotation of the 4th knob 250.Control unit 10 is according to the threshold value of the resistance value selective light transducer S2 of variable resistance.
For example, the position of rotation of the 4th knob 250 is adjusted to the position that approaches " secretly ".In this case, even in the situation that people's transducer S1 detects people, as long as be around bright, control unit 10 is not with regard to the lighting load L1 control of throwing light on.On the contrary, in the case of the position of rotation of the 4th knob 250 being adjusted to the position of " closing ", in the time that people's transducer S1 detects people, control unit 10 and illumination are around independently to the lighting load L1 control of throwing light on.
In the present embodiment, as shown in Figure 8, can from by the selected lower limit illumination of lower limit illumination setting unit 27 with the corresponding dimming level of 10% sum (regulation illumination) of highest luminance level (maximal illumination) to the scope of the corresponding dimming level of 50% (benchmark illumination) of highest luminance level (maximal illumination) be chosen in the upper limit illumination for lighting load L1 in the light modulation time period.Note, in the light modulation time period, be defaulted as 20% of highest luminance level (maximal illumination) for the upper limit illumination of lighting load L1.
Lower limit illumination setting unit 27 is similarly to comprise the first push-button switch B1 and the second push-button switch B2 with illumination setting unit 26.Lower limit illumination setting unit 27 is for the lower limit illumination based on lighting load L1 is set from user's manual input.The first push-button switch B1 is used for reducing lower limit illumination and the second push-button switch B2 for increasing lower limit illumination.
In the present embodiment, illumination setting unit 26 and lower limit illumination setting unit 27 share each push-button switch B1 and B2.In other words, usually, each push-button switch B1 and B2 are as illumination setting unit 26.But each push-button switch B1 and B2 press in response to each push-button switch B1 and B2 time and as lower limit illumination setting unit 27.
In other words, control unit 10 has the pattern that arranges for lower limit illumination.Control unit 10 for arrange pattern to lighting load L1 supply with by the corresponding electric power of the determined lower limit illumination of lower limit illumination setting unit 27.Control unit 10 is in response to switching to by the manual input (pressing when push-button switch B1 and B2) of lower limit illumination setting unit 27 pattern of setting from user.
Each push-button switch B1 and B2 as lower limit illumination setting unit 27 in the situation that display unit 15 glimmer.In other words, in the situation that control unit 10 is in pattern is set, control unit 10 makes display unit 15 keep flicker.Therefore, make user from visually checking that each push-button switch B1 and B2 are as illumination setting unit or lower limit illumination setting unit.
Press the button switch B1 and B2 in the situation that control unit 10 is in pattern is set time, the pattern that arranges stops simultaneously.In other words, control unit 10 is in response to stopping arranging pattern from user by the manual input (pressing when push-button switch B1 and B2) of lower limit illumination setting unit 27.Arrange in the process of pattern in termination, control unit 10 is stored by the determined lower limit illumination of lower limit illumination setting unit 27 (, the dimming level corresponding with lower limit illumination).
Arranging in pattern, control unit 10 to lighting load L1 supply with by the corresponding electric power of the determined lower limit illumination of lower limit illumination setting unit 27.Arranging in pattern, control unit 10 is pressed in response to the first push-button switch B1's, reduces dimming level.In addition, control unit 10 is pressed in response to the second push-button switch B2's, increases dimming level.In this manner, control unit 10 is supplied with the electric power corresponding with the current lower limit illumination of lower limit illumination setting unit 27 to lighting load L1.Therefore, user can select lower limit illumination in the case of checking the actual illumination of lighting load L1.
Make following explanation for how to confirm for the lower limit illumination of lighting load L1.First,, in order to make each push-button switch B1 and B2 as lower limit illumination setting unit 27, press the button switch B1 and B2 simultaneously.Subsequently, in order to search for the dimming level that lighting load L1 is closed, by pressing the first push-button switch B1, reduce the dimming level for lighting load L1.Make, after dimming level that lighting load L1 closes, to press the second push-button switch B2 once finding.By this process, can determine the minimum dimming level that lighting load L1 can be opened.Be equal to, or greater than the dimming level of minimum dimming level and then again press the button switch B1 and B2 in the case of selecting, making each push-button switch B1 and B2 as illumination setting unit 26.Selected dimming level can be stored in control unit 10 as the dimming level corresponding with lower limit illumination.
In the present embodiment, as shown in Figure 8, can from the dimming level corresponding with 0% of highest luminance level (maximal illumination) to the scope of 30% of highest luminance level (maximal illumination) corresponding dimming level select the dimming level corresponding with lower limit illumination for lighting load L1.Note, select as the default value for the lower limit illumination of lighting load L1 in the light modulation time period 10% of highest luminance level (maximal illumination).
First, normal running is described.Normal running refers to the operation in the time period except the light modulation time period (in the present embodiment, normal time section).
As shown in Figure 2, in the situation that people's transducer S1 detects people (moment T11), control unit 10 starts to throw light on to control to increase gradually light and exports to make after process certain hour section (in the present embodiment, 2.5 seconds), and lighting load L1 is in highest luminance.
In other words, in the situation that people's transducer S1 detects people, control unit 10 starts to supply with the electric power corresponding with the initial illumination (the first initial illumination) that is equal to, or greater than lower limit illumination to lighting load L1, and subsequently along with the time increases the electric power that is supplied to lighting load L1 until the electric power corresponding with predetermined expectation illumination (first expects illumination).Control unit 10 increases the electric power that is supplied to lighting load L1 for example to make, at the electric power reaching after certain hour section (2.5 seconds) and expectation illumination (first expects illumination) is corresponding from the electric power corresponding with initial illumination (the first initial illumination).In addition, control unit 10 is increased to from the electric power corresponding with initial illumination (the first initial illumination) electric power that is supplied to lighting load L1 and the electric power of expecting that illumination (first expects illumination) is corresponding with constant increment rate.In addition, initial illumination (the first initial illumination) for example equals, by the determined lower limit illumination of lower limit illumination setting unit 27 (, 10% of maximal illumination).Expect that illumination (first expects illumination) equals the maximal illumination for lighting load L1.
In the situation that people's transducer S1 does not detect people (moment T12), control unit 10 by control that lighting load L1 is thrown light on, light lighting load L1 with dimming level corresponding with 50% the light output (illumination) that equals highest luminance level (maximal illumination), starts to close pre-notice and lights operation.
For example, by illumination section setting unit continuous time 24 determined illumination section continuous time Th (10 seconds) warps after (moment T13), control unit 10 is closed lighting load L1.
In brief, in the situation that people's transducer S1 does not detect people, control unit 10 only for example, is closed pre-notice and is lighted operation in pre-notice time period (6 seconds).
After predetermined amount of time, control unit 10 starts to close pre-notice and lights operation the moment that people do not detected from people's transducer S1.In this respect, predetermined amount of time equals for example, for example, poor (for example 4 seconds) between illumination section Th continuous time (10 seconds) and pre-notice time period (6 seconds).
Close pre-notice light operation in control unit 10 supply with the electric power corresponding with pre-notice illumination (first notifies illumination in advance) to lighting load L1.Through the pre-notice time period in the situation that, control unit 10 stops supplying with to the electric power of lighting load L1.Note, notify in advance illumination (the first pre-notice illumination) be equal to, or greater than lower limit illumination and be less than maximal illumination.For example, notify in advance illumination (the first pre-notice illumination) to equal 50% of maximal illumination.In addition, initial illumination (the first initial illumination) is chosen as and exceedes pre-notice illumination (the first pre-notice illumination).Therefore,, in the situation that people's transducer S1 detects people, control unit 10 is supplied with the electric power corresponding with the illumination higher than pre-notice illumination (the first pre-notice illumination) to lighting load L1.
Operation during the light modulation time period is carried out to following explanation.
As shown in Figure 2, in the situation that people's transducer S1 detects people (moment T21), control unit 10 is first to open lighting load L1 by the determined lower limit illumination of lower limit illumination setting unit 27.Subsequently, control unit 10 throws light on to control to increase gradually light and exports to make to reach the light output (upper limit illumination) corresponding by the determined dimming level of illumination setting unit 26 after through certain hour section (2.5 seconds in the present embodiment).
In other words, in the situation that people's transducer S1 detects people, control unit 10 starts to supply with the electric power corresponding with the initial illumination (the second initial illumination) that is equal to, or greater than lower limit illumination to lighting load L1, and subsequently along with the time increases the electric power that is supplied to lighting load L1 until the electric power corresponding with predetermined expectation illumination (second expects illumination).Control unit 10 increases the electric power that is supplied to lighting load L1 from the electric power corresponding with initial illumination (the second initial illumination), for example, to make to reach and expect the electric power that illumination (second expects illumination) is corresponding after process certain hour section (, 2.5 seconds).In addition, control unit 10 increases to from the electric power corresponding with initial illumination (the second initial illumination) electric power of supplying with to lighting load L1 and the electric power of expecting that illumination (second expects illumination) is corresponding with constant increment rate.In addition, initial illumination (the second initial illumination) for example equals, by the determined lower limit illumination of lower limit illumination setting unit 27 (, 10% of maximal illumination).Expect that illumination (second expects illumination) equals predetermined upper limit illumination.In the present embodiment, upper limit illumination is determined by illumination setting unit 26.In example, upper limit illumination equals 20% of maximal illumination shown in figure 2.
