Fig. 1 is the calcspar of LED lighting control appliance according to an embodiment of the invention.
Referring to Fig. 1, LED lighting control appliance 100 comprises sensor unit 30 and control module 10 according to an embodiment of the invention.In particular, control module 10 can comprise master controller 11, control information storage area 12 and lighting control section and divide 13.And LED lighting control appliance 100 can comprise communication module 40 or be connected to communication module 40.The brightness of the lighting unit 20 that comprises at least one light-emitting diode assembly (LED device) can be adjusted by LED lighting control appliance 100.
Described lighting unit can comprise the light-emitting diode assembly of at least one group (grouped) or at least one indivedual (individual).And lighting unit 20 receives electric power with luminous according to the control command of control module 10.
Lighting unit 20 can irradiate near the installation shape (an installed shape) of light-emitting diode assembly target area (irradiation target region) and luminous with various shot shapes according to being arranged in lighting unit 20 and being positioned at.For instance, lighting unit 20 can send shot shape for circle, bat-wing or linear light.
The light-emitting diode assembly being installed in lighting unit 20 can receive electric power for each indivedual unit or each group unit.That is to say, light-emitting diode assembly can individually receive the electric power differing from one another, and is therefore relative to each other individually controlled.Or the device group that comprises a plurality of light-emitting diode assemblies (device group) can receive electric power and therefore be controlled for each group unit.Or the light-emitting diode assembly being installed in lighting unit 20 can be connected to a power supply, and be therefore controlled together.
Sensor unit 30 can be collected the information of the surrounding environment of target area about being irradiated by lighting unit 20 or lighting unit 20.For this reason, sensor unit 30 can comprise a succession of assembly, for example at least one transducer and analogue-to-digital converters (ADC converter), described analogue-to-digital converters are converted to by the data of the ambient condition information about institute's sensing the value that digital value (digital value) is changed to export.
In an exemplary embodiment, sensor unit 30 can comprise illuminance transducer (not shown) for measuring ambient illuminance and for the motion sensor of the motion of the object in sensed object irradiated region.
That is to say, in an exemplary embodiment, the data generating module (not shown) that comprises the illuminance transducer in a plurality of transducers that comprise in sensor unit 30 and be connected to the analogue-to-digital converters of described illuminance transducer can be converted to by the sensing brightness value of the summation corresponding to external illuminance and lighting illumination intensity (sensed illuminance value) value that can process in control module 10 by described analogue-to-digital converters, thereby handled value is transferred in control module 10, wherein said external illuminance is the illumination causing owing to exterior light, and lighting illumination intensity is the illumination of the light launched by lighting unit 20.Hereinafter, the brightness value of the summation of the external illuminance corresponding to being sensed by illuminance transducer and lighting illumination intensity can be called to the information being contained in the first sense data.
And, in an exemplary embodiment, comprise the motion sensor in a plurality of transducers that comprise in sensor unit 30 and be connected to specification that the data generating module (not shown) of the analogue-to-digital converters of described motion sensor can be based on described transducer with respect to the position of sensor installation and produce and be used for informing that (inform) senses the information of the motion of object in preset range, thus by described communication in control module 10.Hereinafter, the information that whether senses the described motion of described object about described motion sensor can be called to the information being contained in the second sense data.
Communication module 40 is connected to control module 10 so that the control information from external transmission is transferred to control module 10, and subsequently the control information being stored in control module 10 is outputed to outside.
According to current embodiment, because a plurality of lighting unit 20 and LED lighting control appliance 100 are through grouping, so can control together the illumination of broad position.Herein, the control information that can transmit or receive information for calculating the electric power being consumed by lighting unit 20, receive from other LED lighting control appliance or central control system by communication module 40, and the first and second sense datas.
And communication module 40 can be set up near field or far-field communication network.Therefore, can be transferred in other LED lighting control appliance being stored in a control information in LED lighting control appliance.In the time of in control information being transferred to other LED lighting control appliance, can pass through communication module 40 broadcast control informations.Other LED lighting control appliance of receiving control information can indivedual illumination identifications (individual lighting identification) or group's illumination identification (group lighting identification) based on being contained in control information determine whether lighting unit 20 is controlled according to corresponding control information.
As described above, sensor unit 30 produces the first and second sense datas and described the first and second sense datas is transferred in control module 10.As a result, control module 10 receives the first sense data that comprises the brightness value being sensed by the illuminance transducer being adjacent in the surrounding of lighting unit 20 and comprises the second sense data of information that whether senses the motion of object about motion sensor.
Control module 10 can be by using the first and second sense datas that receive from sensor unit 30 to control the illumination of lighting unit 20.
In particular, the output of lighting unit 20 can be controlled, the brightness value that makes to be contained in the first sense data has a value, described value is between a plurality of object illumination values and be matched with between the minimal illumination value of described a plurality of object illumination values, and minimal illumination value has the brightness value that is less than the coupling object illumination value (matched target illuminance values according to the sensing data) obtaining according to the second sense data.
That is to say, control module 10 control described illumination so that lighting unit 20 illumination around (, the illumination of the light of launching during lighting unit 20 in operation be incorporated into the total value of the external illuminance in the position of being irradiated by lighting unit 20 (, be contained in the brightness value in the first sense data)) scope between according between the selected object illumination value of motion that whether senses object and the minimal illumination value setting according to corresponding object illumination value.
Herein, control module 10 receives the first sense data in real time or with predetermined period continuously.Subsequently, control module 10 determines that the scope that is contained in the brightness value in the first sense data is whether between object illumination value and minimal illumination value.If not, control module 10 is controlled the output of lighting unit 20 by FEEDBACK CONTROL so, makes the scope that is contained in the brightness value in the first sense data between object illumination value and minimal illumination value.
In particular, according to the first and second sense datas, with the control command increasing or reduce the output of lighting unit 20, from master controller 11, produce.
In particular, master controller 11 receives the first and second sense datas from sensor unit 30.After this, master controller 11 is by determining whether to sense the motion of object with the second sense data.
Therefore, master controller 11 can be selected one of them object illumination value in a plurality of object illumination values and one of them the minimal illumination value in a plurality of minimal illumination value according to the motion that whether senses object, and described a plurality of object illumination value and described a plurality of minimal illumination value are stored in control information storage area 12.
In particular, a plurality of minimal illumination values that are stored in a plurality of object illumination values in control information storage area 12 and are matched with described a plurality of object illumination values can comprise default first object brightness value (described default first object brightness value is the brightness value before the motion that senses object), be matched with the first minimal illumination value of described first object brightness value, sensing brightness value after the motion of object (, and the second minimal illumination value that is matched with the second object illumination value the second default object illumination value when the motion that senses object).
For instance, if have the output of approximately 8 watts for launching the lighting unit 20 of the light with first object brightness value, the first minimal illumination value that is matched with so first object brightness value can be set to the output of approximately 4 watts of the output that is less than first object brightness value.The brightness value that first object brightness value and the first minimal illumination value representation are sensed by illuminance transducer when the motion that does not sense object.
For launching the output of the lighting unit 20 of the light with the second object illumination value, can be the maximum output (for example, approximately 40 watts) of lighting unit 20.The the second minimal illumination value that is matched with the second object illumination value herein, can be set to the output of approximately 20 watts of the output that is less than the second object illumination value.The second object illumination value and the second minimal illumination value representation when the motion that senses object for example, for bright illumination (bright lighting) is irradiated to the brightness value on object (, people).
Herein, as seen in embodiment as described above, the second minimal illumination value can be greater than first object brightness value.
And the first minimal illumination value and the second minimal illumination value can be the output brightness value of the brightness value being contained in sense data or the lighting unit calculating according to the output of lighting unit 20 20 self.
That is to say, according to embodiments of the invention, when the illumination of lighting unit 20 is controlled according to motion so that sense data is while reaching each in the first brightness value and the second brightness value, the output of lighting unit 20 can be controlled so that sense data higher than the first minimal illumination value and the second minimal illumination value.
According to another embodiment of the present invention, when the illumination of lighting unit 20 is controlled according to motion so that sense data is while reaching each in the first brightness value and the second brightness value, the output of lighting unit 20 self can be controlled so that sense data is not less than the first minimal illumination value or the second minimal illumination value.
That is to say, master controller 11 can be according to being contained in information in the second sense data (, described information is about for informing whether the information of the motion that senses object is sensed) select a pair of brightness value, and this is the first minimal illumination value and the second minimal illumination value that is matched with first object brightness value and the second object illumination value to brightness value.
After this, master controller 11 compares the ambient illuminance value (that is, the brightness value summation of external illuminance and lighting illumination intensity) being contained in the first sense data of lighting unit 20 with object illumination value and the minimal illumination value selected from control information storage area 12.
After this, can produce control command for controlling the output of lighting unit 20, make the scope that is contained in the brightness value in the first sense data between selected object illumination value and minimal illumination value.
For instance, when the brightness value in being contained in the first sense data reaches selected object illumination value, because there is no need further to increase brightness value, so can produce for maintaining or reduce the control command of the output of lighting unit 20.
On the other hand, when the brightness value in being contained in the first sense data does not reach selected minimal illumination value, because should not reduce brightness value, so can produce for increasing the control command of the output of lighting unit 20.
That is to say, master controller 11 can produce control command so that be contained in brightness value in the first sense data corresponding to selected object illumination value and be greater than the minimal illumination value that is matched with selected object illumination value.
Lighting control section divides 13 can control according to the control command producing from master controller 11 output of lighting unit 20.That is to say, when master controller 11 receives the first sense data to produce control command for controlling the first sense data in real time or periodically so that the scope of the first sense data between object illumination value and minimal illumination value time, lighting control section divides 13 according to the real-time control command (real-time control command) that is transferred to lighting unit 20, to come transmission command to control the output of lighting unit 20, and therefore lighting unit 20 is subject to FEEDBACK CONTROL according to the first sense data.
In particular, can the control command that be produced and transmitted by master controller 11 be described as following instance.
Master controller 11 produces control command for controlling the output of lighting unit 20, make the scope that is contained in the brightness value in described the first sense data between first object brightness value and the first minimal illumination value, and make information in being contained in the second sense data be in the normal condition before the motion that senses object (that is, not sensing in the state of motion of object).
Therefore, lighting unit 20 can divide the control command of 13 reception correspondences to increase, reduce or maintain its output from lighting control section in real time.
As described above, if be identified for informing that the packets of information of the motion that senses object is contained in the second received sense data, the simultaneously output of lighting unit 20 be controlled so that the scope that is contained in the brightness value in the first sense data between first object brightness value and the first minimal illumination value, master controller 11 can produce control command for controlling the output of lighting unit 20 during the first default time of delay so, and the brightness value that makes to be contained in the first sense data reaches the second object illumination value.
After this, can produce control command for controlling the output of lighting unit 20, make the scope that is contained in the brightness value in the first sense data between the second object illumination value and the second minimal illumination value.
According to embodiment as described above, the output of lighting unit 20 be controlled and in normal condition (, before the motion that senses object), the scope of the illumination in lighting position is between stored first object brightness value (stored first target illuminance value) and the first minimal illumination value.
Herein, if sense the motion of object, the output that increases so lighting unit 20 within the first time of delay, until the illumination in lighting position reaches the second object illumination value.Subsequently, when illumination reaches the second object illumination value, that is, and when finish the first time of delay, the output of lighting unit 20 can be controlled so that the scope of the illumination in lighting position between the second object illumination value and the second minimal illumination value.
When the output of lighting unit 20 is controlled so that the scope of the first sense data between the second object illumination value and the second minimal illumination value time, master controller 11 can temporarily be stored finally to receive to comprise and be confirmed as for informing the time point of the second sense data of the information that senses object.
That is to say, the time point that finally senses the motion of object in the second data can be updated to latest data in the time durations of the motion of object sensing continuously.If do not sense the motion of object, the second sense data that so finally senses the motion of object can be the time point that finally senses the motion of object in the second sense data.
As described above, master controller 11 storages finally receive the time point of the second sense data, and described the second sense data comprises for informing the information of the motion that senses object.Subsequently, master controller 11 produces control command for controlling the output of lighting unit 20, make to start to the default point of holding time (preset maintining time point) from corresponding time point, the scope of the first sense data is between the second object illumination value and the second minimal illumination value.
After this, if the motion of object is not updated, the output of lighting unit 20 can be controlled so that during the second default time of delay, the brightness value being contained in the first sense data reaches first object brightness value so.
According to embodiment as described above, the output of lighting unit 20 is controlled so that in the state of motion that senses object, and the scope of the illumination in lighting position is between stored the second object illumination value and the second minimal illumination value.
Herein, when the motion of object disappears, described output is controlled so that during default holding time, the scope of the illumination in lighting position is between the second object illumination value and the second minimal illumination value.Subsequently, described output reduces, until the illumination in lighting position reaches first object brightness value during the second time of delay.When illumination reaches first object brightness value, that is, be while finishing for the second time of delay just, output can be controlled so that the scope of illumination between first object brightness value and the first minimal illumination value, the same with normal condition as described above.
In order to carry out function referred to above, master controller 11 can load control information as described above from control information storage area 12, that is, about information, first and second delay time informations of the first and second targets and minimal illumination value, and the information of holding time.Herein, the first and second time of delays and hold time and can be set to same time value or different time value.
Therefore, control information storage area 12 can receive and store outside input by communication module 40 and master controller 11, described outside input comprises information, the first and second delay time informations about the first and second targets and minimal illumination value, and the information of holding time.
According to current embodiment of the present invention, LED lighting can be controlled conventionally so that it is exported lower than first object brightness value and higher than the first minimal illumination value.Subsequently, when sensing the motion of object, LED lighting can be controlled so that it is exported lower than the second object illumination value and higher than the second minimal illumination value.After this, while no longer sensing the motion of object after during holding time, LED lighting can be controlled so that its output lower than first object brightness value and higher than the first minimal illumination value.
And as described above, the second minimal illumination value can be set to has the value that is greater than first object brightness value.
Therefore, can be contemplated to following effect according to the function of lighting control equipment.
First, the brightness of LED lighting can be maintained so that it is exported higher than the first minimal illumination value and the second minimal illumination value.
If sensing ambient illuminance only in the situation that not setting minimal illumination value, LED lighting is controlled to have predetermined luminous intensity, and illumination can be closed so.When this situation also can occur in the motion sensing such as objects such as people.
And, when not setting minimal illumination value, or first object brightness value is during higher than the second minimal illumination value, even if sense the motion of object, the illumination of illumination can not change yet, but be maintained at its initial illumination (for example, the scope of described illumination is between first object brightness value and the first minimal illumination value).
Yet user may wish to move to change according to it brightness of illumination.This is feasible, because when the brightness of illumination changes according to user's motion, user can pick out the running rightly of function of illumination.
Yet, thereby if only with motion sensor and in the situation that not setting minimal illumination value sensing ambient illuminance maintain predetermined luminous intensity and control illumination, so according to the existence of exterior lighting, illumination may not can be opened, or the brightness of illumination may not can change, no matter how people's motion is also like this.In the case, user may suspect that lighting apparatus is out of order or misreads lighting apparatus in abnormality.
And as described below, when controlling described illumination when maintaining predetermined luminous intensity in the situation that not setting minimal illumination value, described illumination can be enclosed remarkable change object illumination is on weekly duty.That is to say, illumination may be broken down, that is, cross bright or excessively dark.In the case, user may misread lighting apparatus in abnormality.In addition,, may there is too much power consumption in the excessive brightness owing to illumination.
With reference to Fig. 4, to Fig. 6, describe restriction as described above in detail.Because lighting control equipment according to the present invention comprises structure as described above and can realize the function described in Fig. 1, so the present invention can solve restriction as described above, thereby to user, provide the stability of controlling about illumination so that throw light on stable and accurately operate according to sensing condition, and the steady illumination control technology that makes minimum power consumption is provided.
In an embodiment of the present invention, lighting unit 20 can calculate power consumption by control information storage area 12 simply extraly.
That is to say, if by communication module 40 by controlled condition communication in control system or office terminal, in so can the whole chart by Fig. 7, illustrated value be easily calculated total electricity consumption, wherein said controlled condition packets of information is containing changing into the second object illumination value and change into the information of the time point of first object brightness value from the second object illumination value from first object brightness value about brightness value, together with about the first and second object illumination values and corresponding to the information of the minimal illumination value of the first and second object illumination values, the first and second delay time informations, and the information of holding time.
That is to say, can measure exactly the power consumption according to light-emitting diode lighting module of the present invention by simple calculating.Therefore, can effectively manage the power consumption of a plurality of light-emitting diode lighting modules.
Fig. 2 illustrates the schematic diagram of the Installation Example of LED light lamp according to an embodiment of the invention.
Referring to Fig. 2, lighting unit 20 can be arranged in precalculated position, and according to the increase from control module 10 transmission or reduce (maintaining) illumination order and be controlled at output facet.Herein, sensor unit 30 can be transferred to control module 10 by comprising about the first sense data of the information of illumination (=external illuminance value+lighting illumination intensity value) and the second sense data of comprising about the information of the motion of object, thereby allows control module 10 to produce control command based on described sense data.
As described above, lighting unit 20, sensor unit 30 and control module 10 can be sold or installed as an encapsulation or a plurality of independent encapsulation.Therefore,, when illumination is irradiated in broad position, can provide a plurality of lighting units 20, sensor unit 30 and control module 10 light is transmitted into each lighting position.
Herein, in the configuration of lighting unit 20, sensor unit 30 and control module 10, sensor unit 30 can be adjacent to lighting unit 20 and arrange, that is, be arranged on the side surface of lighting unit 20.
In existing light emitting diode lighting equipment, for transducer and the lighting module setting separated from one another of sensing illumination.That is to say, transducer can be arranged on from the light of lighting module transmitting and the position of incidence of external light, for example, is arranged on bottom.
In the case, upper because transducer should be arranged on independent position (separate place), thus may need extra position, or control command can change according to the position of transducer.
Yet, if sensor unit 30 is arranged on the side surface of lighting unit 20, can solve so taking and the restrictions such as change of control command such as additional positions.
When sensor unit 30 is arranged on the side surface of lighting unit 20, can adjust together the distance at interval between the specification of sensor unit 30 or sensor unit 30 and lighting unit 20, make light from lighting unit 20 transmittings by bottom reflection and incide sensor unit 30.
In the case, sensor unit 30 can sensing exterior light and from the light of lighting unit 20 transmittings by the brightness value of the light of bottom reflection.In the case, externally the illumination of light and the light during from the direct incident of light of lighting unit 20 transmitting is proportional with the illumination when the reflected light incident.In the case, when the data of processes sensor unit 30, can apply interpolating function (interpllation) easily to measure exactly the illumination of external illuminance and lighting unit 20.
Fig. 3 is the schematic diagram of LED lighting control procedure according to an embodiment of the invention.
As described with reference to figure 1, sensor unit 30 produce about the information of external environment condition 50 with by the communication being produced to control module 10, whether externally described information be the first sense data of illumination and second sense data of the information that comprises the motion that about senses object in environment 50 of sensing lighting unit 20 light around.
Object illumination value and minimal illumination value are stored in control module 10.And, can select different object illumination values and minimal illumination value according to comprising about whether sensing second sense data of information of the motion of object.
After this, control module 10 produces control command according to the described embodiment of Fig. 1, and described control command is transferred to lighting unit 20.Therefore, can control according to control command the output of lighting unit 20.
When the output of lighting unit 20 is controlled, external environment condition 50 can change.In the case, can measure changed environmental information by sensor unit 30, and subsequently can be again by measured communication in control module 10.Therefore, the brightness of lighting unit 20 can be subject to FEEDBACK CONTROL in real time.
Fig. 4 is the chart that the efficiency of the LED lighting control technology of using existing motion sensor is described.
As above described about Fig. 1, in the illumination of using existing motion sensor, control and use in the illumination control of illuminance transducer, can there are some restrictions.In particular, when comparing with function of the present invention, described lighting control technique has various restrictions aspect the realization of function and power consumption minimizing.This will be described at hereinafter with reference Fig. 4, Fig. 5 and Fig. 6.
Referring to Fig. 4, illustrate and only with motion sensor, controlling the brightness in when illumination and the chart of time.
The maximum output of the brightness of illumination is maintained at about 8 watts, corresponding to approximately 20% of maximum output (approximately 40 watts).From time point t1 to time point t2 (that is, just after the motion that senses object), the brightness of illumination increases to maximum output (approximately 100%, that is, approximately 40 watts).
After this, after the motion that senses object, in predetermined hold time (t3-t2), maintain maximum output.Subsequently, from time point t3 to time point t4, the brightness of illumination is reduced to approximately 20% of maximum output again.
In the case, when when maintaining consistently maximum output and compare, electric power has reduced about P1.And, because maintain together illumination brightness and no matter ambient illuminance how, so lighting module may be exported unnecessary illumination according to external illuminance, thereby causes the loss of illumination.Therefore, be difficult to make the minimizing of power consumption to maximize.
Fig. 5 is the chart that the efficiency of the LED light lamp control technology of using existing illuminance transducer is described.
Different from Fig. 4, brightness when only controlling LED lighting with illuminance transducer of Fig. 5 explanation and the chart of time.
In with reference to the described embodiment of figure 5, the brightness of lighting apparatus is controlled so that lighting apparatus has object illumination (approximately 100%, that is, approximately 40 watts).
Yet, in the case, because the illumination of lighting apparatus is only controlled according to object illumination, so can be difficult to prevent that the illumination of lighting apparatus from enlarging markedly or reducing, as certain situation, can be difficult to prevent that lighting apparatus is closed.Herein, though power conservation about P2, but compare with object illumination value while increasing to some extent when brightness value, can lose the electric power corresponding to about S1 as loss electric power.
Fig. 6 is the figure that the example of the tables of data of using in using the LED lighting control technology of existing illuminance transducer is described.
According in the existing illumination control technology with reference to figure 5 described embodiment, can occur as described above corresponding to the restriction in the power consumption of S1 and the tables of data of Fig. 6.
According to existing illumination control technology, can control illumination with reference to the table of figure 6.
That is to say, the data about external illuminance for each cell value are stored in table, but also will be stored in table about being matched with the brightness of illumination information of external illuminance.As a result, in the prior art, when external illuminance changes, that is, when the position that lighting apparatus has been installed changes, should proofread and correct corresponding tables of data.And, because should store the brightness value that is matched with corresponding brightness value according to the change of external illuminance value, so the amount of the data that will store may be excessive.
Yet, different from the described embodiment of Fig. 6, because by storing or load very small amount of data (, only about first object and minimal illumination value, the second target and minimal illumination value, the first and second time of delays and the data of holding time) control the brightness of illumination, so the lighting control equipment described in the embodiment of Fig. 1 can reduce data loss.
Fig. 7 illustrates the chart of the efficiency of LED lighting control device according to an embodiment of the invention.
In with reference to figure 4 to Fig. 6 described embodiment, by the efficiency of describing about the prior art of power conservation.
Referring to the chart of Fig. 7, according to embodiments of the invention, the brightness of lighting unit 20 be controlled At All Other Times so that the scope of brightness at first object brightness value (approximately 20%,, approximately 8 watts) and the first minimal illumination value (approximately 10%, that is, approximately 4 watts) between.
From different to the described prior art of Fig. 6 with reference to figure 4, according to the present invention, because there is the minimum value about the first sense data, so the brightness of lighting unit 20 can be maintained at the value that is greater than predeterminated level all the time.And, because be contained in brightness value in the first sense data lower than first object brightness value, thus the output of lighting unit 20 can be controlled according to external illuminance, thus stably control the output of lighting unit 20, and do not cause significant exporting change.
When time point t2 senses the motion of object, within the first time of delay (t1 is to t2), increase the output of lighting unit 20, make the first sense data reach the second object illumination value (approximately 100%, that is, approximately 40 watts).After this, the output of lighting unit 20 be controlled so that the scope of exporting between the second object illumination value and the second minimal illumination value (approximately 60%, that is, 24 watts), the scope of the first sense data is between the second object illumination value and the second minimal illumination value
If only there is the second object illumination, even if sense so the motion of object, also according to outside brightness, do not increase or open the brightness of illumination herein.As described above, in the case, user may misread lighting apparatus in abnormality.
Yet, in the present invention, because set the minimal illumination value (it can be greater than first object brightness value and using as the second minimal illumination value) when the motion that senses object, thus the output of lighting unit must be controlled to provide lighting apparatus normally and stably operation reliability.And the output of lighting unit 20 can not can exceedingly increases or reduces, thereby prevent that lighting apparatus from damaging and allowing stably to control lighting apparatus.
While passing through the default time point t3 holding time after arriving the motion that is sensing object, within the second time of delay (t3 is to t4), control the brightness of lighting unit 20, make the first sense data again reach first object brightness value.After this, with time point t1 before time the same, the output of lighting unit 20 be controlled so that the scope of the first sense data between first object brightness value and the first minimal illumination value.
In the case, if do not set the first minimal illumination value, if Fig. 4 is to as shown in Fig. 6, the illumination of lighting unit 20 may significantly reduce so, makes illumination lower than the first minimal illumination value.Subsequently, if illumination turns back to first object brightness value, owing to the excessive control to output, may shorten the useful life of light-emitting diode assembly, or system loading may occur so.
Yet, set the first minimal illumination value and significantly change and brought new effect to prevent the brightness of illumination, and then solved restriction as described above.
