As shown in Figure 2, wireless transmitter 10 comprises: power supply 11 provides drive electricity; Personage's transducer 12, whether the someone occurs sensing; Lightness transducer 13, the sensitive context lightness; Control unit 14 produces control signal; Switch 15 is operated based on the control signal that is produced by control unit 14; And infrarede emitting diode (LED) 16, the emission infrared ray.
For example, power supply 11 comprises battery.This power supply 11 provides drive electricity to above-mentioned wireless transmitter 10.
For example, personage's transducer 12 comprises thermoelectric element etc., and the heat ray of the human body institute radiation that in sensing region, occurs through sensing comes sensing, and whether the someone occurs.When personage's transducer 12 senses the someone when occurring, consequent sensing signal is provided to control unit 14.
For example, lightness transducer 13 comprises phototransistor etc., and the sensitive context lightness.The sensing signal of lightness transducer 13 is offered control unit 14.
For example, control unit 14 comprises microcomputer etc.To control unit 14 sensing signal is provided from personage's transducer 12.When personage's transducer 12 provides sensing signal; Control unit 14 produces the control signal that comprises luminance signal and opening time signal based on the sensing signal that provides from lightness transducer 13; Wherein luminance signal is indicated the surrounding environment lightness, the opening time that each illuminating equipment is opened in opening time signal indication.Then, control unit 14 offers switch 15 with the control signal that produces.
In addition, though do not specifically illustrate, comprise the timer that the time is counted in the control unit 14.Control unit 14 activates this timer in the output control signal.This timer is counted opening the indicated opening time of time signal.
In addition; After the output control signal; Control unit 14 produces the prolongation signal as control signal based on sensing signal that provides from personage's transducer 12 or the sensing signal that provides from personage's transducer 12 and lightness transducer 13 respectively, and this prolongation signal is used to prolong the opening time of each illuminating equipment.Particularly, if when lighting apparatus be when no matter how the environment lightness has the people to occur just continuing to open the type of illuminating equipment, 14 of control units produce the prolongation signal based on the sensing signal that provides from personage's transducer 12.In addition; When lighting apparatus is only (for example to be lower than the predetermined luminance grade in the environment lightness; At night etc.) and when just continuing to open the type of illuminating equipment when having the people to occur, control unit 14 produces based on the sensing signal that provides from personage's transducer 12 and lightness transducer 13 respectively and prolongs signal.Then, control unit 14 provides the prolongation that is produced signal to switch 15.
For example, switch 15 comprises the switch element of transistor and so on.Switch 15 is operated based on the control signal that is produced by control unit 14, to open infrared LED 16.
The lighting apparatus that comprises above-mentioned wireless transmitter 10 is right after after the timer internal completion counting of the control unit 14 in relevant wireless transmitter 10, through lightness transducer 13 sensing surrounding environment lightness, thereby prevents that illuminating equipment is inoperative.
Particularly, sense after the surrounding environment lightness is lower than the predetermined luminance grade at lightness transducer 13, shown in the Reference numeral among Fig. 3, wireless transmitter 10 senses the someone through personage's transducer 12 and (shown in the Reference numeral b among Fig. 3) occur.At this moment, under the control of control unit 14, wireless transmitter 10 transmits control signal to receiver, and this control signal comprises: " secretly " signal, and as luminance signal, indication surrounding environment lightness is lower than the predetermined luminance grade; And the opening time signal, the opening time of relevant illuminating equipment, for example 10 seconds are opened in indication.In response to this control signal, receiver 20 is increased to high level with load output, opening illuminating equipment, and activates the timer internal of receiver 20 itself, the opening time is counted beginning.Indicated " bright " signal that the surrounding environment lightness is equal to or higher than the predetermined luminance grade as luminance signal even receive; Receiver 20 also continues to open illuminating equipment, up to having passed through the indicated time span of opening time signal by the opening time of timer internal counting.
Simultaneously; Shown in Reference numeral c and d among Fig. 3; Under the control of control unit 14; Wireless transmitter 10 is with for example per 5 seconds predetermined time intervals once, and through lightness transducer 13 sensing surrounding environment lightness, and definite surrounding environment is brighter than the predetermined luminance grade of wireless transmitter 10 illuminating equipments of being opened own.
Then, shown in the Reference numeral e among Fig. 3, under the control of control unit 14, wireless transmitter 10 is right after after timer internal finishes counting, through lightness transducer 13 sensing surrounding environment lightness.In this case; Wireless transmitter 10 senses the surrounding environment lightness through lightness transducer 13 and is lower than the predetermined luminance grade; This is that the illuminating equipment that itself opened by wireless transmitter 10 this moment extinguishes because current state is the state after timer internal finishes counting.Then; Shown in the Reference numeral f among Fig. 3; When personage's transducer 12 senses the someone when occurring; Wireless transmitter 10 transmits control signal to receiver 20 under the control of control unit 14, and this control signal comprises: " secretly " signal is sensing the lightness determined value of someone before occurring as being right after; And the opening time signal, the opening time of illuminating equipment is opened in indication.In response to this control signal, receiver 20 is increased to high level with load output, opening illuminating equipment, and activates timer internal, the opening time is counted beginning.
As stated, the timer internal that is right after the control unit 14 in wireless transmitter 10 is accomplished after the counting, and lighting apparatus obtains the surrounding environment lightness that is sensed by lightness transducer 13 through control unit 14.Like this, even be right after after timer internal finishes counting (for example, in thereafter one second), lighting apparatus also can be opened illuminating equipment sensing through personage's transducer 12 definitely when the someone occurs.
Here, lighting apparatus possibly cause the error between the timer internal of timer internal and receiver 20 of wireless transmitter 10.Therefore, because this error, in lighting apparatus, following situation can occur: even according to the timer internal of wireless transmitter 10, to must closing time of illuminating equipment, illuminating equipment still is held open according to the timer internal of receiver 20.In this case; In lighting apparatus following situation possibly appear: when illuminating equipment is held open; Lighting apparatus passes through lightness transducer 13 sensing surrounding environment lightness, and exports " bright " signal by error as luminance signal, so can't correctly control illuminating equipment.
Therefore, wireless transmitter 10 provides the scheduled time (for example, being right after in after the timer internal of control unit 14 finishes counting one second) conduct to be used to absorb the error soak time of above-mentioned error.Like this, hope to sense within this error soak time under the situation that the someone occurs, wireless transmitter 10 keeps standbies and does not transmit control signal, and after lightness transducer 13 sensing lightness, transmits control signal.
Particularly, sense the surrounding environment lightness at lightness transducer 13 and be lower than predetermined luminance grade (shown in the Reference numeral a among Fig. 4) afterwards, wireless transmitter 10 senses the someone through personage's transducer 12 and occurs, shown in the Reference numeral b among Fig. 4.Then, under the control of control unit 14, wireless transmitter 10 transmits control signal to receiver, and this control signal comprises: " secretly " signal, and as luminance signal, indication surrounding environment lightness is lower than the predetermined luminance grade; And the opening time signal, the opening time of relevant illuminating equipment, for example 10 seconds are opened in indication.In response to this control signal, receiver 20 is increased to high level with load output, opening illuminating equipment, and activates the timer internal of receiver 20 itself, the opening time is counted beginning.Indicated " bright " signal that the surrounding environment lightness is equal to or higher than the predetermined luminance grade as luminance signal even receive; Receiver 20 also continues to open illuminating equipment, up to having passed through the indicated time span of opening time signal by the opening time of timer internal counting.
Simultaneously; Shown in Reference numeral c and d among Fig. 4; Under the control of control unit 14; Wireless transmitter 10 is with for example per 5 seconds predetermined time intervals once, and through lightness transducer 13 sensing surrounding environment lightness, and definite surrounding environment is brighter than the predetermined luminance grade of wireless transmitter 10 illuminating equipments of being opened own.
Then; Be right after after timer internal finishes counting; Wireless transmitter 10 does not pass through lightness transducer 13 sensing surrounding environment lightness, but shown in the Reference numeral e among Fig. 4, under the control of controller 14; Passed through after a second as the error soak time, just through lightness transducer 13 sensing surrounding environment lightness.In this case; Wireless transmitter 10 senses the surrounding environment lightness through lightness transducer 13 and is lower than the predetermined luminance grade; This is that the illuminating equipment that opened by wireless transmitter 10 this moment extinguishes because current state is the state after timer internal finishes counting.Then; Within the error soak time; When personage's transducer 12 senses the someone when occurring, shown in the Reference numeral f among Fig. 4, wireless transmitter 10 transmits control signal to receiver 20 under the control of control unit 14; This control signal comprises: " secretly " signal, as the lightness determined value of timing place shown in the Reference numeral e among Fig. 4; And the opening time signal, the opening time of illuminating equipment is opened in indication.In response to this control signal, receiver 20 is increased to high level with load output once more, opening illuminating equipment, and activates timer internal, the opening time is counted beginning.
As stated, the timer internal of the control unit 14 of lighting apparatus in wireless transmitter 10 finishes after the counting predictive error soak time to be provided.Then, sensing within this error soak time under the situation that the someone occurs, lighting apparatus keeps standby and does not transmit control signal, and then after obtaining the surrounding environment lightness that is sensed by lightness transducer 13, transmits control signal.Like this, even between the timer internal of the timer internal of wireless transmitter 10 and receiver 20, occur under the situation of error, lighting apparatus also can suitably be controlled illuminating equipment.
Note, under the situation of this method of employing, occur about one second time lag at most, and lighting apparatus can cause user's sense of discomfort.
In this case; When the timer internal of wireless transmitter 10 begins to carry out counting according to " secretly " signal as luminance signal; And when personage's transducer 12 senses the someone when occurring within the error soak time; Wireless transmitter 10 can send luminance signal to receiver 20, and in this luminance signal, the lightness determined value is rewritten as " secretly ".
Particularly, sense the surrounding environment lightness when being lower than the predetermined luminance grade at lightness transducer 13, shown in the Reference numeral a among Fig. 5, wireless transmitter 10 senses the someone through personage's transducer 12 and occurs, shown in the Reference numeral b among Fig. 4.Then, under the control of control unit 14, wireless transmitter 10 transmits control signal to receiver, and this control signal comprises: " secretly " signal, and as luminance signal, indication surrounding environment lightness is lower than the predetermined luminance grade; And the opening time signal, the opening time of relevant illuminating equipment, for example 10 seconds are opened in indication.In response to this control signal, receiver 20 is increased to high level with load output, opening illuminating equipment, and activates the timer internal of receiver 20 itself, the opening time is counted beginning.Indicated " bright " signal that the surrounding environment lightness is equal to or higher than the predetermined luminance grade as luminance signal even receive; Receiver 20 also continues to open illuminating equipment, up to having passed through the indicated time span of opening time signal by the opening time of timer internal counting.
Simultaneously; Shown in Reference numeral c and d among Fig. 5; Under the control of control unit 14; Wireless transmitter 10 passes through lightness transducer 13 sensing surrounding environment lightness with for example per 5 seconds predetermined time intervals once, and definite surrounding environment is brighter than the predetermined luminance grade of wireless transmitter 10 illuminating equipments of being opened own.
Then; Timer internal end counting when wireless transmitter 10; And personage's transducer 12 senses the someone when occurring within the error soak time, shown in the Reference numeral e among Fig. 5, wireless transmitter 10 transmits control signal to receiver 20 under the control of control unit 14; This control signal comprises: luminance signal, wherein the lightness determined value is forced to be rewritten as " secretly "; And the opening time signal, the opening time of illuminating equipment is opened in indication.In response to this control signal, receiver 20 is increased to high level with load output once more, opening illuminating equipment, and activates timer internal, the opening time is counted beginning.
As stated, sensing within this error soak time under the situation that the someone occurs, lighting apparatus sends luminance signals to receiver 20, and the lightness determined value is rewritten as " secretly " in this luminance signal.Like this, even after closing illuminating equipment automatically, lighting apparatus also can almost opened illuminating equipment under the not free state that lags behind immediately, and can strengthen the user's security sense.
Notice that in the time needn't changing the place of sensing lightness neatly, lighting apparatus can provide function and lightness transducer 13 similar lightness transducer in receiver 20 sides rather than in wireless transmitter 10 sides.Particularly, receiver 20 receives control signal from wireless transmitter 10, and this control signal comprises the opening time signal, is used to indicate the opening time of opening illuminating equipment.Then; Under the control of the control unit (not shown) in receiver 20; Receiver 20 is controlled illuminating equipment based on the opening time signal with from the sensing signal that the lightness transducer provides; And when receiving control signal, activate timer internal, thereby count opening the indicated opening time of time signal.Then, under the control of control unit, receiver 20 is right after after timer internal finishes counting and obtains the surrounding environment lightness that is sensed by the lightness transducer.
State in the use under the situation of receiver 20, lighting apparatus only need send the opening time signal through wireless transmitter 10, thus, needn't carry out above-mentioned complicated operations.
In addition, in receiver 20 sides, together with the lightness transducer, lighting apparatus can provide hand switch etc., and this hand switch is as the setup unit that is used for the opening time is set.Particularly; Under the control of control unit (not shown); Receiver 20 is controlled illuminating equipment based on the opening time that is set by hand switch with from the sensing signal that the lightness transducer provides; And when receiving sensing signal, activate timer internal, thereby the opening time that hand switch sets is counted.Then, under the control of control unit, receiver 20 is right after after timer internal finishes counting and obtains the surrounding environment lightness by lightness transducer sensing.
State in the use under the situation of receiver 20, needn't by wireless transmitter 10 send luminance signals and opening time signal the two, therefore, lighting apparatus can be simplified signal, and can reduce power consumption.In addition, even install under the situation of wireless transmitter 10 in a large amount of places, lighting apparatus also can significantly reduce following situation: these signals overlap each other, and receiver 20 can't be discerned coherent signal.
In addition; In receiver 20 sides; Be provided for setting together with the lightness transducer under the situation of open-interval hand switch etc., lighting apparatus can be set respectively: the opening time under the situation of opening illuminating equipment based on the control signal of sending from wireless transmitter 10; And based on the opening time that sets by hand switch and the sensing signal that provides from the lightness transducer and open the opening time under the situation of illuminating equipment.Like this, lighting apparatus can be set respectively by the opening time of wireless transmitter 10 temporary transient unlatching illuminating equipments and the opening time of temporarily opening illuminating equipment by receiver 20 (hand switch), and can enhancing usability.
As above specifically said; In lighting apparatus according to the embodiment of the invention; When personage's transducer 12 senses the someone when occurring; Wireless transmitter 10 produces under the control of control unit 14 and exports control signal, and this control signal comprises: luminance signal, and indication is based on the surrounding environment lightness of the sensing signal that provides from lightness transducer 13; And the opening time signal, the opening time of illuminating equipment is opened in indication.In addition, in the output control signal, wireless transmitter 10 activates its timer internal, and counts opening the indicated opening time of time signal.Then, under the control of control unit 14, wireless transmitter 10 is right after after timer internal finishes counting and obtains the surrounding environment lightness that is sensed by lightness transducer 13.
Like this,, sense the someone when occurring, also can open illuminating equipment definitely even be right after after the timer internal of wireless transmitter 10 finishes counting personage's transducer 12 according to this lighting apparatus.
In addition; In wireless transmitter 10; When personage's transducer 12 senses the someone when occurring in the scheduled time after the timer internal of control unit 14 finishes counting; Control unit 14 can keep standby and not export control signal, and can after obtaining the surrounding environment lightness that is sensed by lightness transducer 13, export control signal.Like this, according to this lighting apparatus,, also can suitably control illuminating equipment even between the timer internal of the timer internal of wireless transmitter 10 and receiver 20, occur under the situation of error.
In addition; In wireless transmitter 10, when personage's transducer 12 senses the someone when occurring in the scheduled time after the timer internal of control unit 14 finishes counting, control unit 14 is exported luminance signals; In this luminance signal, the lightness determined value is forced rewriting.Like this, even after illuminating equipment cuts out automatically, wireless transmitter 10 also can almost opened illuminating equipment under the not free state that lags behind immediately, and can strengthen the user's security sense.
In addition, according to this lighting apparatus, can the lightness transducer be provided in receiver 20 sides.In this case; When receiving the control signal that comprises the opening time signal that the opening time of opening illuminating equipment is indicated from wireless transmitter 10, receiver 20 is controlled illuminating equipment based on the opening time signal with from the sensing signal that the lightness transducer provides.When receiving control signal, receiver 20 activates timer internal, thereby counts opening the indicated opening time of time signal.Then, receiver 20 is right after after timer internal finishes counting and obtains the surrounding environment lightness that is sensed by the lightness transducer.
Like this, according to this lighting apparatus, 10 needs of wireless transmitter send the opening time signal, therefore needn't carry out complicated operations.
