Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Fig. 1 is the schematic block diagram of the illumination control apparatus 100 illustrated according to the embodiment of the present invention.
As shown in fig. 1, testing circuit 101, governor circuit 102, drive circuit 103 and switching circuit 104 is comprised according to the illumination control apparatus 100 of the embodiment of the present invention.
Testing circuit 101 is for detecting the input signal from outside.Governor circuit 102 for determining whether the mode of operation of converted illumination control device 100 according to input signal, and controls drive circuit 103 and switching circuit 104 works under the mode of operation of correspondence.Drive circuit 103, under the control of governor circuit 102, drives light-emitting diode (LED) lamp at least one in cold light source and warm light source luminous and regulates the luminosity of LED.Switching circuit 104, under the control of governor circuit 102, switches cold light source and warm light source.
According in the illumination control apparatus 100 of the embodiment of the present invention, the mode of operation of illumination control apparatus 100 comprises normal mode and sleeping pattern, and in sleeping pattern, drive circuit 103 drives the LED in warm light source luminous, keep LED brightness during first time period constant, and the brightness of LED is reduced until LED turns off during section the remaining time in sleeping mode duration after first time period gradually.Here, first time period is one period of scheduled time after self-service sleep mode starts, and is included in sleeping mode duration.
In one example in which, drive circuit 103 utilizes pulse-width signal to regulate the brightness of LED.
Therefore, according to the embodiment of the present invention, after entering sleeping pattern, the brightness of light fixture can decline gradually after maintenance first time period, and brightness is reduced to 0 at the end of sleeping mode duration, and namely light fixture is completely switched off.Therefore, achieve the effect that light fixture is dimmed gradually, and the problem causing human body sensitivity to be waken up with a start due to light sudden change can not be caused.
Meanwhile, according to the embodiment of the present invention, during the first time period in sleeping pattern, the brightness of light fixture remains unchanged, and which eliminates people because know that the brightness of light fixture can dimmed and psychological hint that is that cause it.This psychological hint may make people unconsciously expect in use or how dimmed undue attention light fixture is, so that cannot loosen, and result causes the effect not having hypnosis.On the contrary, the illumination control apparatus 100 according to the embodiment of the present invention can eliminate this psychological hint, makes people fully to loosen and to enter sleep state fast, therefore, and hommization more.
According to the embodiment of the present invention, in the normal mode, drive circuit 103 can drive the LED in cold light source luminous separately, also can drive the LED mixed luminescence in cold light source and warm light source, and LED in warm light source can be driven with high brightness luminescent.Under sleeping pattern, usual drive circuit 103 drives the LED in warm light source luminous with low-light level.
Usually, people feel to loosen most in the surround lighting of fine day dusk, and the now brightness of surround lighting is not high, and colour temperature is generally 4000K (Kelvin) below, and now surround lighting is partially red warm light.According to inventor's statistics, the light of 2500K ~ 3000K colour temperature contributes to human body to be loosened, and gives a kind of comfortable sensation of people, therefore, the light in this reference color temperature can be carried out low-light level output, to make space environment seem more warm, thus play function for assisting sleep.In one example in which, in sleeping pattern, adopt warm light source luminous, and the colour temperature of LED in warm light source is between 2500K-3000K.
In one example in which, first time period is 10-15 minute, and sleeping mode duration is 30 minutes.Although not shown in FIG, timer (or multiple) can also be comprised according to the illumination control apparatus 100 of the embodiment of the present invention, to carry out timing to first time period and sleeping mode duration.In addition, governor circuit 102 itself also can have timing function, and without the need to independent timer.
Fig. 2 illustrates the schematic diagram of the brightness of LED during sleeping pattern according to the embodiment of the present invention.
As shown in Figure 2, in sleeping pattern, the brightness of the LED in warm light source remained unchanged in first 15 minutes, and declined gradually in latter 15 minutes and just drop to 0 when arrival 30 minutes, thus turned off LED.But this is only an example, but the embodiment of the present invention is not limited thereto.Those skilled in the art can understand, can arrange, and can adopt other time span during manufacture illumination control apparatus 100 to the length of sleeping mode duration and first time period.
In one example in which, user can have a distant control function by remote controller or other intelligent terminal, such as mobile phone, computer etc. input the input signal controlled light fixture.
In another example, different from the equipment adopting remote controller to control light fixture etc., also can be inputted by single switch on wall by user according to the input signal that the testing circuit 101 in the illumination control apparatus 100 of the embodiment of the present invention detects.
Testing circuit 101 can detect the low and high level conversion of input signal.When the high level-low level-high level conversion of input signal is in conversion command section input time, governor circuit 102 can determine the mode of operation of converted illumination control device, and conversion command section input time is the time period for inputting conversion command.
That is, when during the conversion command input time section of input signal from high level is converted to low level, if it changes high level into from low level again, then governor circuit 102 can determine the mode of operation of converted illumination control device, such as be transformed into sleeping pattern from normal mode of operation, or from sleeping Mode change to normal mode.
In one example in which, conversion command section input time is 1-5 second.
In addition, governor circuit 102 can also comprise counter (not shown), for counting working mode change.
In one example in which, when user's first passage opening switch gives me a little bright light tool, the value n of counter can be reset to 0.Here, switch can be single switch on wall, also can be the single push-button switch on remote controller or intelligent terminal.At this moment, the mode of operation of illumination control apparatus 100 is normal mode, drive circuit 103 can drive the LED in cold light source with such as 100% high brightness luminescent, also can drive the LED mixed luminescence in cold light source and warm light source, or can also drive the LED in warm light source with such as 100% high brightness luminescent.Concrete light emitting species can be decided by Default Value, or is arranged voluntarily by user and decide.After this, when user wishes in bed, can shutdown switch, and within 1-5 second opening switch again, this is again opened and makes the value of counter increase progressively 1, i.e. n=1.In addition, testing circuit 101 detects this high level-low level-high level conversion, and governor circuit 102 judges that the conversion of this high level-low level-high level completes within 1-5 second, thus determine the working mode change of illumination control apparatus 100 to be sleeping pattern, and drive circuit 103 drives the LED in warm light source luminous with low-light level.After this, if user's no longer console switch, then illumination control apparatus 100 auto-breaking at the end of sleeping mode duration.
Switching circuit 104 can comprise the first switch and second switch, is respectively used to control switching on and off of the LED in cold light source and the LED in warm light source.But the present invention is not limited thereto, switching circuit 104 also can comprise single switch to switch cold light source and warm light source.
Here, because the single push-button switch on single switch, i.e. single switch on wall or remote controller or intelligent terminal can be utilized to input order for patten transformation, so simplify circuit structure, user operation and memory is convenient to.
Although in the following description with single switch on wall for example is described, those skilled in the art can understand, the function that obviously also can realize below with remote controller or intelligent terminal.Except needs increase except transceiving device, be similar for the explanation of remote controller and intelligent terminal with the explanation for single switch on wall, therefore repeat no more here.
(a) and (b) in Fig. 3 illustrates the signal schematic representation for determining whether transformation working pattern according to the embodiment of the present invention.
As shown in (a) in Fig. 3, if user prepares sleep, when its moment t1 first opening switch time, input signal is high level from low transition, the value n of this hour counter is for being reset to 0, illumination control apparatus 100 enters normal mode, and the LED in cold light source is with 100% Intensity LEDs.User is at t2 moment shutdown switch.If user is at t3 moment opening switch again, and time interval between t2 and t3 is within 1-5 second, then illumination control apparatus 100 is converted to sleeping pattern from normal mode, the value n=1 of this hour counter.If after this user's no longer console switch, then illumination control apparatus 100 at the end of sleeping mode duration, i.e. moment t3 auto-breaking, now LED is also extinguished completely.Or, if user at the end of sleeping mode duration is not, i.e. moment t4 ' shutdown switch and after this no longer console switch again, although then now LED also do not extinguish completely, illumination control apparatus 100 also power-off be forced shutdown LED.
On the other hand, can also carry out repeatedly between normal mode and sleeping pattern according to the illumination control apparatus 100 of the embodiment of the present invention, even unlimited multiple conversions.As shown in (b) in Fig. 3.When user is at moment t4 ' shutdown switch, afterwards moment t5 again opening switch time, the time interval between t4 ' and t5 is 1-5 second, then the value n of counter increases progressively 1, i.e. n=2.Now, governor circuit 102 judges n=2>1, thus the value n of counter can be reset to 0 again, so illumination control apparatus 100 enters normal mode again at moment t5.After this, if user is at moment t6 shutdown switch and at moment t7 opening switch again, and the time interval between t6 and t7, then illumination control apparatus 100 was converted to sleeping pattern at moment t7 from normal mode, the value n=1 of this hour counter within 1-5 second.Then, if user is at moment t8 shutdown switch, afterwards at moment t9 opening switch again, the time interval between t8 and t9 is 1-5 second, then the value n of counter increases progressively 1, i.e. n=2, so governor circuit 102 judges n=2>1 and the value n of counter is reset to 0 again, illumination control apparatus 100 enters normal mode again at moment t9.Circulate according to this.
In addition, the time interval in Fig. 3 between each moment is only schematic, and does not represent real time interval ratio.Such as, the time interval between t1 and t2 can be very long, and this can correspond to the user when light fixture is lit the long period and wish the situation entering sleeping pattern.Alternatively, the time interval between t1 and t2 can be very short, is also such as about 1-5 second, and this can correspond to light fixture and originally be in the situation that off-position and user wish to enter sleeping pattern.
Illustrated in Fig. 3 that illumination control apparatus 100 comprises the situation of two kinds of mode of operations, but the present invention is not limited thereto, illumination control apparatus 100 can also comprise other more mode of operations.Such as, illumination control apparatus 100 can also comprise half-light pattern, in half-light pattern, LED in cold light source can with the Intensity LEDs of 30%-50%, or the LED in warm light source can with the Intensity LEDs of 30%-50%, or LED in cold light source and warm light source is luminous with the luminance mix of 30%-50%.
(a) and (b) in Fig. 4 shows according to another embodiment of the present invention for determining whether the signal schematic representation of transformation working pattern, and wherein the mode of operation of illumination control apparatus 100 comprises normal mode, half-light pattern and sleeping pattern.
Similar in signal schematic representation shown in Fig. 4 and Fig. 3, so repeat no more here.But, it should be noted that because the mode of operation of the illumination control apparatus 100 in Fig. 4 has three kinds, so as the value n=3 of counter, governor circuit 102 judges n=3>2, thus illumination control apparatus 100 returns to normal mode, and n is reset to 0.
It will be appreciated by those skilled in the art that, when in Fig. 3 and Fig. 4, each order of operation and the value n of counter equal each numerical value, corresponding operating state is only schematic, and in practice can according to circumstances sets itself.
When illumination control apparatus 100 comprises more than situation during three kinds of mode of operations similar to the above, repeat no more here.
In addition, in one example in which, governor circuit 102 can also comprise electrical storage device (not shown), for powering for governor circuit 102 in conversion command section input time after input signal is in low level.Like this, can ensure that, during conversion command section input time of 1-5 second, the timer sum counter in governor circuit 102 is all work and can not be reset, to guarantee that the value of counter can correctly be increased progressively.
Therefore, according to the embodiment of the present invention, repeatedly can repeat the switching of mode of operation, and sleeping pattern can be cancelled by single switch.
In addition, the switching of sleeping pattern and normal mode of operation can be controlled only by single switch on wall because of not using a teleswitch according to the illumination control apparatus 100 of the embodiment of the present invention, greatly reduce cost.In addition, because without the need to carrying out wireless transmission in such example, so do not need wireless receiving and dispatching parts according to the illumination control apparatus 100 of the embodiment of the present invention, circuit is simple, and this not only provides cost savings further, and reduces overall volume.
In fact, although remote controller can carry out wireless operated, along with the equipment used a teleswitch in life gets more and more, often need to distinguish will use which remote controller on earth when people are simultaneously in the face of multiple remote controller, this has brought worry.In addition, when the remote controller needing to use just even is not placed on other rooms on hand, finding remote controller also can allow people feel trouble.Moreover, in some rural areas or for old user, remote controller very not accustomed to using.Therefore, when not being equipped with remote controller according to the illumination control apparatus 100 of the embodiment of the present invention, more convenience can having been brought, and vast range of application can have been had.
In illumination control apparatus 100, drive circuit 103 is connected to load, i.e. LED, to drive it luminous.But due to the quantity of LED of output series connection and their respective operating voltages different, the normal power supply of drive circuit 103 may be affected.That is, the normal working voltage of drive circuit 103 depends on the characteristic of connected output loading, it raises along with output voltage and raises, reduce and reduce, the operating voltage of drive circuit 103 will be made like this may to exceed the higher limit of the supply power voltage of the chip comprised in it or the minimum value lower than supply power voltage, thus cause whole circuit working abnormal, and then LED is caused to occur the phenomenon of flicker.
Fig. 5 is the schematic block diagram that illumination control apparatus 500 is according to another embodiment of the present invention shown.
In Figure 5, illumination control apparatus 500 comprises testing circuit 501, governor circuit 502, drive circuit 503 and switching circuit 504, and in addition, illumination control apparatus 500 also comprises voltage-multiplying circuit 505.Testing circuit 501, governor circuit 502, drive circuit 503 and switching circuit 504 have identical function and structure with the testing circuit 101 shown in Fig. 1, governor circuit 102, drive circuit 103 and switching circuit 104, therefore repeat no more here.
Voltage-multiplying circuit 505 is connected to drive circuit 503, for the operating voltage of stabilized driving circuit 503.Therefore, voltage-multiplying circuit 505 avoids the phenomenon of operating voltage with the characteristic variations of load of drive circuit 503, makes the operating voltage of drive circuit 503 be in stationary value, to avoid causing other anomalies.In one example in which, the series voltage upper limit of output cool colour temperature LED is greatly about DC 200V, and the series voltage lower limit of output warm colour temperature LED is greatly about DC 5V.
In one example in which, resistance-capacitance coupling and voltage-stabiliser tube and diode multiplication of voltage can be utilized to realize voltage-multiplying circuit 505, but the embodiment of the present invention is not limited thereto.
Thus, the illumination control apparatus 500 according to the embodiment of the present invention has higher constant current accuracy, and current ripples is little, and therefore can use non-isolated power supply, thus reduce further cost, reduces volume, improves cost performance.In addition, because non-isolated power supply is without the need to transformer, finished product light fixture is made not have shade.
In addition, as shown in Figure 5, the illumination control apparatus 500 according to the embodiment of the present invention can also comprise power-supplying circuit 506, is connected to drive circuit 503, for cutting off the power supply of drive circuit 503 at the end of sleeping mode duration.
Thus, by power-supplying circuit 506, disconnection and the connection of drive circuit 503 chips can be controlled, to realize the power supply cutting off chip after sleeping mode duration terminates completely, to reduce the soft copy loss of power in the unloaded state wherein, realize energy-conservation.
Although illumination control apparatus 500 shown in Figure 5 comprises both voltage-multiplying circuit 505 and power-supplying circuit 506, in actual applications, at least one in voltage-multiplying circuit 505 and power-supplying circuit 506 can be comprised.Such as, when being applied to the high-power applications being greater than 25 watts, voltage-multiplying circuit 505 and power-supplying circuit 506 can be removed.In addition, be less than in the low-power applications of 25 watts, can weigh energy-conservation with become originally to determine whether to increase power-supplying circuit 506.
Fig. 6 and Fig. 7 illustrates that wherein, Fig. 6 illustrates high-power for power factor application, and Fig. 7 illustrates low-power applications according to the illumination control apparatus of the embodiment of the present invention schematic physical circuit figure when practical application respectively.
Physical circuit figure in Fig. 6 and Fig. 7 is only schematic, and it will be appreciated by those skilled in the art that, the embodiment of the present invention is not limited thereto.Further, depend on actual design requirement, any suitable change and modification can be carried out.
