In this article, term luminous intensity is used to refer to any applicable measurement of the light intensity that light source is provided.For example, this luminous intensity can be the measurement of the illumination intensity surveyed with the every solid angle of lumen (lm/sr) or with candela (cd).As further example, this luminous intensity can be with every square metre of lumen (lm/m 2) illumination and the measurement of luminosity or with every square metre of candela (cd/m 2) measurement of the brightness of surveying.As example further, the luminous intensity being provided by light source can be directly be used to drive the electric current of this light source and/or voltage proportional, and this electric current and/or this voltage can thus serve as the measurement of this luminous intensity.For example, for LED light source, this luminous intensity can be directly the measurement to leading (prevailing) electric current of its supply.As further example, at given electric current and/or given voltage, control duty cycle (duty cycle) of pulse-width modulation (PWM) signal of luminous intensity of light source or duty ratio can be directly and this to dominate (prevailing) luminous intensity proportional, so that 100% duty cycle implied the maximum light intensity of light source at given electric current and/or given voltage, 60% duty cycle has for example implied that light source is in 60% of the maximum light intensity of given electric current and/or given voltage, 40% duty cycle has for example implied that light source is in 40% of the maximum light intensity of given electric current and/or given voltage, Deng.Luminous intensity measurement discussed herein is as unrestriced example set, and thus, do not depart under the prerequisite of protection scope of the present invention, can adopt other luminous intensity measurements applicatory.
These two or more light sources 240 can be connected or be coupled to this controller 220, and these two or more light sources 240 can directly or via intermediary element be coupled to this controller 220.The first light source 240a of these two or more light sources 240 can provide the light of the first color, and the secondary light source 240b of these two or more light sources 240 can provide the light of the second color.This first color and the second color can be visibly different predetermined colors.Alternatively, the first color can be the similar or substantially similar color under difference predetermined colour temperature with the second color, for example white under different predetermined colour temperatures.In other words, this first light source 240a can be the light source of the first color or the first colour temperature, and secondary light source 240b can be the light source of the second color or the second colour temperature, and wherein the first color or the first colour temperature are different from the second color or the second colour temperature.As further replacement, this first color and the second color can be the similar or basic similarly colors under similar or basic similarly colour temperature.
As specific example, the first light source 240a can provide at colour temperature B 1white light and secondary light source 240b can provide at colour temperature B 2white light, wherein B 1<B 2.The first and second light source 240a, 240b can be controlled so as to be provided from B 1to B 2scope in colour temperature: in the time that the merging luminous intensity of the first and second light source 240a, 240b depends on separately the first light source 240a, the colour temperature obtaining is B 1, but in the time depending on separately secondary light source 240b, the colour temperature obtaining is B 2.For example, if the first light source 240a contributes 60% of this merging luminous intensity, and secondary light source 240b contributes 40% of this merging luminous intensity, in other words, if the ratio between the luminous intensity that the luminous intensity being provided by the first light source 240a and secondary light source 240b provide is 60/40=1.5, the colour temperature obtaining is so 0.6 × B 1+ 0.4 × B 2.Thus, the first and second light source 240a, this example of 240b are arranged to provide needed colour temperature by the relative light intensity of correspondingly adjusting this first and second light source 240a, 240b.
It is above-mentioned by the example of needed colour temperature is provided with two light sources that the light under the predetermined colour temperature of fixing, differ from one another can be provided, generally change into the layout that comprises the other light sources except the first and second light source 240a, 240b, generally change into two or more light sources 240, its each light that can both provide colour temperature to be different from the colour temperature of other light sources, wherein the colour temperature of this merging is the weighted sum of the colour temperature of two or more light sources 240, and this weighted factor is indicated the ratio of the merging luminous intensity of being contributed by light source separately.Along similar thinking, above-mentioned example is generalized to the layout of two or more light sources 240, each light source can both provide color to be different from the light of the color of other light sources, wherein merging color is the weighted sum of the color of two or more light sources 240, and this weighted factor is indicated the ratio of the merging luminous intensity of being contributed by light source separately.
Get back to this controller 220, this importation can be configured to, in the time receiving input control signal and/or during receiving this input control signal, determine the duration t of input control signal in.Especially, this importation 222 can be configured to determine this duration t infor input control signal meets duration of the period of predetermined properties.For example, this predetermined properties can comprise that control signal exceedes or be less than the requirement of predetermined voltage level.As another example, this predetermined properties comprises that this control signal shows the requirement of the electric current that exceedes or be less than scheduled current level in addition or alternatively.This importation 222 can further be configured to the duration of this input control signal of determining to offer control section 224.
This importation 222 can be configured to monitor this input control signal, and monitor especially the duration at this input control signal of this input control signal reception period.Monitor and generally can relate to importation 222 or controller 220, thereby keep and upgrade the information of the duration about still accumulating at the input control signal continuing, and this information can be used, so that for example via the definite operation of controlling this first and second light source 240a, 240b to one or more corresponding output control signals for control section 224.Supervision may further include detect the end of input control signal and provide its indication to this control section 224 for following additional information, this additional information can be utilized controlling in the first and second light source 240a, 240b.
This importation 222 can be configured to monitor based on monitoring period the reception of the sequence of input control signal.If a pair of continuous input control signal is by being less than predetermined threshold t mthe time interval separately, they can be considered to belong to same sequence so.Especially, this predetermined threshold t mcan define the maximum time between the end of the first input control signal and the beginning of this second input control signal to continuous input control signal of a pair of continuous input control signal, wherein this is considered to belong to same sequence to continuous input control signal.Monitor that the sequence of input control signal makes it possible to control the first and second light source 240a, 240b or instead, the sequence based on input control signal is controlled the first and second light source 240a, 240b except the duration based on input control signal.
This control section 224 can be configured to determine the duration t of determined this input control signal inwhether do not exceed the first predetermined threshold Th l1and/or whether the determined input control signal duration exceedes the second predetermined threshold Th l2.The first predetermined threshold Th l1be set to the value of the upper limit of the duration of the input control signal of the input control signal that is considered to short, and the second predetermined threshold Th l2be set to the duration t of the input control signal of the input control signal that is considered to long inthe value of lower limit, thereby for example make it possible to, according to the duration of this input control signal and sequence (being classified as short signal or long signal according to single input control signal), for example, by the determining and composition of one or more output control signals, or the parameter that is in addition used for by control the operation of controlling the first and second light source 240a, 240b is controlled the first and second light source 240a, 240b.Preferably, the first predetermined threshold Th l1be set to equal value with the second predetermined threshold ThL2, to guarantee that each input control signal is classified into short or long signal.But, likely adopt the second predetermined threshold Th l2value higher than the first predetermined threshold Th l1thereby, guarantee the clearer differentiation between short and long input.But this method causes the duration to fall within Th l1and Th l2between input control signal be neither classified as the short long input control signal that is not also classified as, it may need the special processing of the input control signal to the duration in the middle of this.
This control section 224 is configured in response to whole duration t inbe no more than the first predetermined threshold Th l1single input control signal, control and be switched on or switched off this two or more optical elements 240.If this first and second light source 240a, the current disconnection of 240b, control so and can comprise that this control section 224 controls the more multiple light courcess of connecting in these the first light source 240a and secondary light source 240b and possible two or more light sources 240.If this first and second light source 240a, the current connection of 240b, control so and may further include this control section 224 and control the more multiple light courcess disconnecting in these the first light source 240a and secondary light source 240b and possible two or more light sources 240.Due to the whole duration tin of also unknown this input control signal before stopping at this input control signal, so in this, the operation of controlling the first and second light source 240a, 240b can not start, until received input control signal completely.
This control section 224 can be configured in the time disconnecting this two or more light source 240, will indicate the information of the leading ratio (prevailing ratio) between this first light source 240a and the luminous intensity of secondary light source 240b and/or the information of the leading merging luminous intensity that indication is provided by the first and second light source 240a, 240b to be stored in memory.Can in this controller 220, provide sort memory, or this memory in addition can be addressable by controller 220.For example, this information can be included in the information of indicating the luminous intensity of the first light source 240a and the luminous intensity of secondary light source 240b while disconnecting this two or more light source 240.As another example, this information can be included in the information of indicating the luminous intensity of the first light source 240a or the luminous intensity of secondary light source 240b and leading ratio between the two while disconnecting this two or more light source 240.These information for example make it possible in the time disconnecting the first and second light source 240a, 240b to connect the first and second light source 240a, 240b with the ratio of luminous intensity and/or with the luminous intensity of the merging that adopts.
This control section 224 can be configured to obtain the message of indication from desired ratio this memory, between the first light source 240a and the luminous intensity of secondary light source 240b when this two or more light source 240 connecting, and be configured to connect the first light source 240a and secondary light source 240b, to the desired ratio between luminous intensity is provided.This luminous intensity separately that can relate to read from this memory is connected the first light source 240a and secondary light source 240b.Alternatively, the different light intensity degree of this luminous intensity having read since memory since can relating to is connected the first light source 240a and secondary light source 240b, and still keep the desired ratio between the luminous intensity of the first and second light source 240a, 240b, in the time connecting two or more light source 240, make it possible to provide with the desired ratio between them thus expectation or that may be scheduled to, the combined light intensity of the first and second light source 240a, 240b.
This control section 224 is further configured to the duration t in response to this input control signal inexceed the second predetermined threshold Th l2the characteristic of the light being provided by the first and second light source 240a, 240b is provided.The duration of this input control signal is depended in the change of the characteristic of light, and this change comprises the ratio of adjusting between the luminous intensity of the first light source 240a and the luminous intensity of secondary light source 240b.In other words, this change comprises the relative light intensity of adjusting the first and second light source 240a, 240b.As previously discussed, the second predetermined threshold Th l2value be not less than the first predetermined threshold Th l1.At the second predetermined threshold Th l2value be greater than the first predetermined threshold Th l1situation under, this control section 224 is configured to ignore the duration and falls within the input control signal between the first and second predetermined thresholds so.
As example, the first and second predetermined threshold Th l1and Th l2can for example be set to the value in 300 to 450 milliseconds of scopes, for example, be set to 350 milliseconds.As another example, the first predetermined threshold Th l1can be set to the value in 200 to 300 milliseconds of scopes, for example, be set to 250 milliseconds, and the second predetermined threshold Th l2can be set to the value in 300 to 450 milliseconds of scopes, for example, be set to 350 milliseconds.But these values are only as example and in protection scope of the present invention, any Th that makes in the first and second predetermined thresholds l1≤ Th l2value be applicatory.For example, this predetermined threshold t mcan be set to the value in 100 to 300 milliseconds of scopes, for example, be set to 200 milliseconds.
This control section 224 can be configured to the luminous intensity by increase by the first light source 240a about the luminous intensity of secondary light source 240b, until this input control signal stops or until reach the maximum light intensity of the first light source 240a or the minimum light intensity (first whichever occurs) of secondary light source 240b, adjust the ratio between the luminous intensity of the first and second optical element 240a, 240b.In context, maximum light intensity refers to the maximum intensity of the selected 240a of light source separately, 240b, and---it can be the maximum light intensity that light source 240a, 240b separately can provide---is known as the absolute maximum light intensity of light source 240a, 240b separately in this article.Alternatively, selected maximum light intensity can be lower than the luminous intensity of the predetermined selection of the absolute maximum light intensity of light source 240a, 240b separately.Similarly, in this context, minimum light intensity refers to the minimum light intensity of the selected 240a of light source separately, 240b, and it is generally zero for example light source 240a, 240b separately and substantially disconnects, or alternatively, this minimum light intensity can be the predetermined non-zero optical intensity of selecting.
With similar route, this control section 224 can be configured to the luminous intensity by reduce by the first light source 240a about the luminous intensity of secondary light source 240b, until the termination of this input control signal or until reach the maximum light intensity of the first light source 240a or the maximum light intensity (first whichever occurs) of secondary light source 240b, adjust the ratio between the luminous intensity of the first and second optical element 240a, 240b.As in earlier examples, selected maximum light intensity can be the absolute maximum intensity of light source separately or lower than the absolute luminous intensity of the predetermined selection of maximum intensity, and selected minimum light intensity can be zero or the predetermined non-zero optical intensity of selecting.
Increasing about the luminous intensity of secondary light source 240b in the context of luminous intensity of the first light source 240a, can be at least operate in the adjustment of ratio while reaching one or two in the maximum intensity of the first light source 240a and the minimum light intensity of secondary light source 240b with two kinds of different modes.As the first example, as above as described in, can, in response to the termination of input control signal or in response to arriving the maximum light intensity of the first light source 240a and the minimum light intensity of secondary light source 240b one, stop the adjustment of this ratio.As the second example, the adjustment of this ratio can continue, until this input control signal stops or until reached the maximum light intensity of the first light source 240a and the minimum light intensity of secondary light source 240b.This can relate in the time reaching the maximum light intensity of the first light source 240a the luminous intensity of the first light source 240a is remained on to its maximum, and continue to adjust the luminous intensity of (minimizing) secondary light source 240b, until reach its minimum value, and/or in the time reaching the minimum light intensity of secondary light source 240b, the luminous intensity of secondary light source 240b is remained on to its minimum value, and continue to adjust the luminous intensity of (increase) first light source 240a, until arrive its maximum.Reducing about the luminous intensity of secondary light source 240b in the situation of luminous intensity of the first light source 240a, in the time reaching the minimum light intensity of the first light source 240a and/or the maximum light intensity of secondary light source 240b, similar consideration is effective.
Cause reducing the luminous intensity of the first light source 240a about the luminous intensity of secondary light source 240b in the up-to-date adjustment of this ratio, this control section 224 can be configured to the luminous intensity by increase by the first light source 240a about the luminous intensity of secondary light source 240b so, adjusts this ratio.On the contrary, cause increasing the luminous intensity of the first light source 240a about the luminous intensity of secondary light source 240b in the up-to-date adjustment of this ratio, this control section 224 can be configured to the luminous intensity by reduce by the first light source 240a about the luminous intensity of secondary light source 240b so, adjusts this ratio.In this context, up-to-date ratio adjustment refers to and is caused by up-to-date input control signal, and the up-to-date ratio adjustment being caused by the up-to-date input control signal having stopped (by the input control signal before up-to-date, rather than by " current " input control signal still continuing) especially.
The luminous intensity that increases by the first light source 240a about the luminous intensity of secondary light source 240b can comprise the luminous intensity that increases by the first light source 240a and the luminous intensity that does not change secondary light source 240b.Therefore, also increase the luminous intensity of the merging of the first and second light source 240a, 240b.As the variation of this technology, the luminous intensity that increases by the first light source 240a about the luminous intensity of secondary light source 240b can comprise the luminous intensity that reduces secondary light source 240b and the luminous intensity that does not change the first light source 240a, and this causes reducing the merging luminous intensity of this first and second light source 240a, 240b.
Similarly, the luminous intensity that reduces by the first light source 240a about the luminous intensity of secondary light source 240b can comprise the luminous intensity that reduces by the first light source 240a and the luminous intensity that does not change secondary light source 240b, and result is to reduce the merging luminous intensity of this first and second light source 240a, 240b.Relevant technologies comprises, do not change the luminous intensity of the first light source 240a by increasing the luminous intensity of secondary light source 240b, reduce the luminous intensity of the first light source 240a about the luminous intensity of secondary light source 240b, cause thus the merging luminous intensity that increases this first and second light source 240a, 240b.
As further option, the luminous intensity that increases by the first light source 240a about the luminous intensity of secondary light source 240b can comprise, make the luminous intensity of the first light source 240a increase by the first amount and make the luminous intensity of secondary light source 240b reduce by the second amount, the first amount is more than or equal to the second amount.Especially, the first amount can equal the first amount, causes that thus ratio adjustment will be performed, so that the merging luminous intensity of the first light source 240a and secondary light source 240b keeps constant or substantial constant.Similarly, the luminous intensity that reduces by the first light source 240a about the luminous intensity of secondary light source 240b can comprise, make the luminous intensity of the first light source 240a reduce by the first amount and make the luminous intensity of secondary light source 240b increase by the second amount, preferably situation is that the first amount and the second amount equate, cause that ratio adjustment will be performed, so that the merging luminous intensity of the first light source 240a and secondary light source 240b keeps constant or substantial constant.
As example, this ratio adjustment may further include, after reaching (selected) maximum light intensity of the first light source 240a and (selected) minimum light intensity of secondary light source 240b one or both, do not consider the situation of this input control signal and stop this ratio adjustment.This ratio adjustment can comprise equally, after reaching (selected) minimum light intensity of the first light source 240a and (selected) maximum light intensity of secondary light source 240b one or both, do not consider that the situation of this input control signal stops this ratio adjustment.
As the first replaceable example, this ratio adjustment can comprise, after reaching (selected) maximum light intensity of the first light source 240a and (selected) minimum light intensity of secondary light source 240b one or both, reduce the luminous intensity of the first light source 240a about the luminous intensity of secondary light source 240b, until input control signal stops or until reaches (selected) minimum light intensity of the first light source 240a or (selected) maximum light intensity (first whichever occurs) of secondary light source 240.Alternatively, can continue this ratio adjustment, until this input control signal stops or until reaches (selected) minimum light intensity of the first light source 240a and (selected) maximum light intensity the two (first whichever occurs) of secondary light source 240.Similarly, this ratio adjustment can comprise, after reaching (selected) minimum light intensity of the first light source 240a and (selected) maximum light intensity of secondary light source 240b one or both, increase the luminous intensity of the first light source 240a about the luminous intensity of secondary light source 240b, until input control signal stops or until reaches (selected) maximum light intensity of the first light source 240a or (selected) minimum light intensity (first whichever occurs) of secondary light source 240b.Alternatively, can continue this ratio adjustment, until this input control signal stops or until reaches (selected) maximum light intensity of the first light source 240a and (selected) minimum light intensity the two (first whichever occurs) of secondary light source 240b.
As the example of the second replacement, this ratio adjustment can comprise, after reaching (selected) maximum light intensity of the first light source 240a and (selected) minimum light intensity of secondary light source 240b one or both, the luminous intensity of the first light source 240a is set to its (selected) minimum light intensity and the luminous intensity of secondary light source 240b is set to its (selected) maximum light intensity, and increase subsequently the luminous intensity of the first light source 240a about the luminous intensity of secondary light source 240b, until input control signal stops or until reaches (selected) maximum light intensity of the first light source 240a or (selected) minimum light intensity (first whichever occurs) of secondary light source 240b.Alternatively, can continue this ratio adjustment, until this input control signal stops or until reaches (selected) maximum light intensity of the first light source 240a and (selected) minimum light intensity the two (first whichever occurs) of secondary light source 240b.Similarly, this ratio adjustment can comprise, after reaching (selected) maximum light intensity of the first light source 240a and (selected) minimum light intensity of secondary light source 240b one or both, the luminous intensity of the first light source 240a is set to its (selected) maximum light intensity and the luminous intensity of secondary light source 240b is set to its (selected) minimum light intensity, and reduce subsequently the luminous intensity of the first light source 240a about the luminous intensity of secondary light source 240b, until input control signal stops or until reaches (selected) maximum light intensity of the first light source 240a or the minimum light intensity (first whichever occurs) of (selected) secondary light source 240b.Alternatively, can continue this ratio adjustment, until this input control signal stops or until to reach the first light source 240a(selected) maximum light intensity and (selected) minimum light intensity the two (first whichever occurs) of secondary light source 240b.
In the first and second replacement examples, it is in response to reaching as mentioned above first or secondary light source 240a, 240b (selected) maximum and/or (selected) minimum light intensity and operating, this ratio adjustment may further include, before the ratio between the luminous intensity of further adjusting the first and second light source 240a, 240b, wait for scheduled time slot t w, it can be known as the stand-by period.This stand-by period is used for promoting to set the ratio of luminous intensity, and it relates to its (selected) maximum or minimum light intensity or approaches its (selected) maximum or minimum light intensity operates first and/or secondary light source 240a, 240b.For example, waiting time t wcan be set to the value in the scope of 0.5 to 1.5 second, for example, be set to one second.
This control section 224 can further be configured such that the merging luminous intensity that can adjust the first and second light source 240a, 240b, rather than the ratio adjustment between the luminous intensity of the first and second light source 240a, 240b is only provided.In other words, in response to the duration t of input control signal inexceed the second predetermined threshold Th l2the change of characteristic of light may further include, adjust the merging luminous intensity of the first light source 240a and secondary light source 240b.Preferably implement this and adjust, so that the ratio between this first light source 240a and the luminous intensity of secondary light source 240b keeps constant or substantial constant.
Especially, this control section 224 can be configured to have and exceed the second predetermined threshold Th in response to single input control signal l2duration t in, carry out in a continuous manner the adjustment of the luminous intensity of this ratio adjustment and merging.The adjustment of this continuous light characteristic can comprise, first adjust this merging luminous intensity and do not change this ratio, subsequently according to the duration of this input control signal and according to first and/or the current light intensity of secondary light source 240a, 240b adjust this ratio.
In this, this control section 224 can be configured to the duration t in response to this input control signal inexceed the second predetermined threshold Th l2, change by adjusting the merging luminous intensity of this first light source 240a and secondary light source 240b the light characteristic being provided by the first and second light source 240a, 240b, to keep the ratio of this luminous intensity not change or substantially do not change.This control section 224 can be configured to continue to adjust merge luminous intensity, until this input control signal stops, arrival the first and second light source 240a, 240b (selected) is maximum merges luminous intensity or until reaches the first and second light source 240a, 240b (selected) minimum luminous intensity (first whichever occurs) that merges.This control section 224 can further be configured to pass through scheduled time slot t in response to (selected) that certainly reach the first and second light source 240a, 240b maximum luminous intensity that merges cTthis input control signal continues afterwards, adjusts ratio between the first light source 240a and the luminous intensity of secondary light source 240b and change the characteristic of light according to the first pre-defined rule.In other words, if t xrepresent to reach (selected) maximum moment that merges luminous intensity of the first and second light source 240a, 240b, after being illustrated in the maximum merging luminous intensity that reaches (selected), passed through scheduled time slot t so cTt x+ t cTthis ratio of Shi Qidong is adjusted.
Cause and reduce this merging luminous intensity at up-to-date input control signal above, the adjustment of the merging luminous intensity of the first and second light source 240a, 240b can comprise increases this merging luminous intensity, and/or cause and increase this merging luminous intensity at up-to-date input control signal above, the adjustment of the merging luminous intensity of the first and second light source 240a, 240b can comprise this merging luminous intensity of minimizing.
As mentioned above, (selected) that relate to above maximum, and to merge intensity can be that wherein at least one of the first and second light source 240a, 240b reached the luminous intensity of its (selected) maximum light intensity.Although this method makes available maximum merge luminous intensity and depends on current intensity rate, it makes it possible to utilize completely the ability of the first and second light source 240a, 240b simultaneously, to provide maximum luminous intensity at current luminous intensity ratio.
As another example, can be according to the maximum luminous intensity that merges of the leading limitation in light intensity (selected) of the first and second light source 240a, 240b, if so that the first light source 240a operates with the y% of its (selected) maximum light intensity with x% operation and the secondary light source 240b of its (selected) maximum light intensity, the merging value of x+y does not allow to exceed 100% so.In other words, should (maximum) merging luminous intensity can be by the limited proportion of (selected) separately maximum light intensity of the first and second light source 240a, 240b, thus (selected) is maximum while merging luminous intensity this ratio and be 100%.Although this method may not exclusively be utilized the ability of the first and second light source 240a, 240b, but it has nothing to do the obtainable maximum ratio merging between luminous intensity and the luminous intensity of the first and second light source 240a, 240b simultaneously, and condition is that the first and second light source 240a, 240b (selected) maximum light intensity equate or substantially equate.
Although (selected) being merged to the above-mentioned example of the ratio of maximum light intensity (selected) individual luminous intensity based on the first and second light source 240a, 240b provides for controlling (selected) merging maximum light intensity under the ratio in leading luminous intensity, but this for example may cause in the unequal situation of (selected) maximum light intensity of the first and second light source 240a, 240b, (selected) that makes to discover merges maximum light intensity and depends on the leading ratio of luminous intensity.In interchangeable exemplary method, (selected) merging maximum light intensity is set to the minimum value of (selected) maximum light intensity of the first light source 240a and (selected) maximum light intensity of secondary light source 240b.Therefore, limit this merging luminous intensity, so that the smaller value luminous intensity of the first and second light source 240a, 240b and that do not allow to exceed (selected) maximum light intensity of the first light source 240a and (selected) maximum light intensity of secondary light source 240b.In this method, it is also irrelevant with this leading luminous intensity ratio in the case of (selected) maximum light intensity of the first and second light source 240a, 240b is different that (selected) merges maximum intensity.
(selected) minimum merge luminous intensity preferably wherein any of the first and second minimum light source 240a, 240b reached the luminous intensity of its (selected) minimum light intensity.Alternatively, (selected) minimum intensity that merges can be the luminous intensity that has both reached its (selected) minimum light intensity of light source 240a, 240b wherein.But this replacement method can cause before reaching (selected) minimum light intensity of two light source 240a, 240b that the ratio between luminous intensity changes.
Alternatively, have and exceed the second predetermined threshold Th in response to single input control signal l2duration t inthe continuous setup of characteristic of light can comprise, first adjust the ratio between this luminous intensity, adjust and merge luminous intensity and do not change this ratio subsequently, be wherein fixed against the duration of this input control signal and be fixed against first and/or the current luminous intensity of secondary light source 240a, 240b implement this adjustment.
In this, this control section 224 can be configured to, and by adjusting the ratio between this first light source 240a and the luminous intensity of secondary light source 240b, carrys out the duration t in response to this input control signal inexceed the second predetermined threshold Th l2, the characteristic of the light that change is provided by the first and second light source 240a, 240b.This control section 224 can be configured to, and continues to adjust this ratio until this input control signal stops until reach (selected) maximum light intensity of the first light source 240a or (selected) minimum light intensity of secondary light source 240b or until reach (selected) minimum light intensity of the first light source 240a or (selected) maximum light intensity (first whichever occurs) of secondary light source 240b.Alternatively, can continue to adjust this ratio, until this input control signal stops until reach (selected) maximum light intensity of the first light source 240a and (selected) minimum light intensity of secondary light source 240b or until reach (selected) minimum light intensity of the first light source 240a and (selected) maximum light intensity (first whichever occurs) of secondary light source 240b.
Control section 224 can further be configured to, in response to certainly reaching described (selected) maximum light intensity of the first light source 240a and/or described (selected) minimum light intensity of secondary light source 240b has been passed through scheduled time slot t cTthis input control signal continues afterwards, makes to keep the ratio of this luminous intensity not change or substantially do not change by adjust the merging luminous intensity of the first light source 240a and secondary light source 240b according to the second pre-defined rule, changes the characteristic of light.Along this thinking described above, if t yrepresent to reach the moment of described (selected) maximum light intensity of the first light source 240a and/or described (selected) minimum light intensity of secondary light source 240b, so at t y+ t cTthe adjustment of this merging luminous intensity of Shi Qidong, wherein t y+ t cTbe illustrated in after reaching described (selected) maximum light intensity of the first light source 240a and/or described (selected) minimum light intensity of secondary light source 240b and passed through scheduled time slot t cT.
Cause about the luminous intensity of secondary light source 240b and reduce the luminous intensity of the first light source 240a at up-to-date input control signal above, this ratio adjustment can comprise that the luminous intensity by increase by the first light source 240a about the luminous intensity of secondary light source 240b adjusts this ratio so.On the contrary, cause about the luminous intensity of secondary light source 240b and increase the luminous intensity of the first light source 240a at this up-to-date input control signal above, this ratio adjustment can comprise that the luminous intensity by reduce by the first light source 240a about the luminous intensity of secondary light source 240b adjusts this ratio in addition or alternatively so.
For example, this scheduled time slot t cTcan be in the scope of 1 to 5 second, for example 3 seconds.But these values provide as just non-restrictive example, and in the situation that not departing from protection scope of the present invention, this scheduled time slot can have the value beyond the scope of example.This ratio adjustment also can be used whole users, thereby avoiding in the case of from adjusting this merging luminous intensity (to should (selected) maximum) to the unwanted long delay the change of this ratio adjustment, for this scheduled time slot t cTshort value for example 1 second or still less, can be favourable.On the other hand, thus being intended to reduce casual user for attendant in this ratio adjustment surprisingly activates this ratio and adjusts function dangerous, so for scheduled time slot t cTthe value for example 5 seconds or more of length, can be useful.
The first pre-defined rule for adjusting the ratio between the luminous intensity of the first and second light source 240a, 240b relating to hereinbefore can comprise, by increasing the luminous intensity of the first light source 240a about the luminous intensity of secondary light source 240b until this input control signal stops or until to reach the first light source 240a(selected) one of (selected) minimum light intensity of maximum light intensity and secondary light source 240b or both, adjust this ratio.
Can comprise for the first pre-defined rule of adjusting the ratio between the luminous intensity of the first and second light source 240a, 240a, cause increasing the luminous intensity of the first light source 240a about the luminous intensity of secondary light source 240b at the up-to-date input control signal above that causes this ratio adjustment, by increase the luminous intensity of the first light source 240a about the luminous intensity of secondary light source 240b, adjust this ratio.On the contrary, the first pre-defined rule can comprise, cause reducing the luminous intensity of the first light source 240a about the luminous intensity of secondary light source 240b at the up-to-date input control signal above that causes this ratio adjustment, adjust this ratio by the luminous intensity that reduces by the first light source 240a about the luminous intensity of secondary light source 240b.In other words, the first pre-defined rule can be included in and the equidirectional of up-to-date ratio adjustment on continue the ratio adjustment between the luminous intensity of the first and second light source 240a.

The second pre-defined rule that is used for the merging luminous intensity of adjusting the first and second light source 240a, 240b may further include, after reaching (selected) maximum merging luminous intensity of the first light source 240a and secondary light source 240b, reduce the luminous intensity of the first light source 240a and secondary light source 240b, to keep the ratio between it not change or substantially do not change, until this input control signal stops or until reach the first light source 240a and secondary light source 240b (selected) minimum luminous intensity (first whichever occurs) that merges.On the contrary, in addition or alternatively, the second pre-defined rule may further include, after reaching (selected) minimum merging luminous intensity of the first light source 240a and secondary light source 240b, increase the luminous intensity of the first light source 240a and secondary light source 240b, to keep ratio between it not change or substantially do not change, until this input control signal stops, or until reach the first light source 240a and secondary light source 240b(selected) the maximum luminous intensity (first whichever occurs) that merges.
Along in the above thinking of the first pre-defined rule this point, the second pre-defined rule can comprise further, before further adjusting this merging luminous intensity, after reaching (selected) maximum merging luminous intensity and/or (selected) minimum merging luminous intensity of the first and second light source 240a, 240b, apply stand-by period t as above w.
Replace the duration t in response to single input control signal inexceed the second predetermined threshold Th l2and the continuous setup of the merging luminous intensity of application to the ratio between the luminous intensity of the first and second light source 240a, 240b and the first and second light source 240a, 240b, this control section 224 can be configured to the duration t in response to single input control signal inexceed the second predetermined threshold Th l2, and alternately adjust the ratio of luminous intensity and merge luminous intensity.
Especially, this control section 224 can be configured to, and has caused the adjustment of merging luminous intensity of the first light source 240a and secondary light source 240b, in response to the duration t of single input control signal at up-to-date input control signal above inexceed the second predetermined threshold Th l2, adjust the ratio between the first light source 240a and the luminous intensity of secondary light source 240b according to the first pre-defined rule, until the termination of this input control signal.On the contrary, this control section 224 can be configured to, and has caused the adjustment of ratio between the first light source 240a and the luminous intensity of secondary light source 240b, in response to the duration t of single input control signal at up-to-date input control signal above inexceed the second predetermined threshold Th l2, according to the second pre-defined rule adjust the first light source 240a and secondary light source 240b merging luminous intensity until this input control signal stop so that keep the ratio of this luminous intensity not change or substantially do not change.This can be considered to the method for adjusting the ratio between luminous intensity or merging luminous intensity for the current state according to controller 220, and wherein this condition responsive is in having duration t inexceed the second predetermined threshold Th l2each input control signal and change.
As the duration t in response to input control signal inexceed the second predetermined threshold Th l2according to the ratio between the current state adjustment luminous intensity of controller 220 or the interchangeable exemplary method of merging luminous intensity, this control section can be configured to adjust the ratio between luminous intensity in the first state and adjust in the second state and merge luminous intensity.
Especially, in the first state, this control section 224 can be configured to, for example, by increase the luminous intensity of the first light source 240a about the luminous intensity of secondary light source 240b, adjust the ratio between the first light source 240a and the luminous intensity of secondary light source 240b, until this input control signal stops or until reaches (selected) maximum light intensity of the first light source 240a or (selected) minimum light intensity (first whichever occurs) of secondary light source 240b.Alternatively, can continue this ratio adjustment, until this input control signal stops or until reaches (selected) maximum light intensity of the first light source 240a and (selected) minimum light intensity (first whichever occurs) of secondary light source 240b.In the second state, this control section 224 can be configured to, adjust the merging luminous intensity that increases or reduce the first light source 240a and secondary light source 240b, to keep the ratio of this luminous intensity not change or substantially do not change, until this input control signal stops or until reach that the first and second light source 240a, 240b (selected) is maximum merges luminous intensity or until to reach the first and second light source 240a, 240b(selected) the minimum luminous intensity that merges.
This control section 224 can be configured to, control signal in response to predetermined number changes to the state of controller 220 the second state or changes to the first state from the second state from the first state, and wherein each control signal has and is no more than the first predetermined threshold Th l1the whole duration.As non-restrictive example, this " short " input control signal that causes this predetermined number of the change between the first and second states can be for example two.Especially, this control section 224 can be configured to, sequence in response to " short " control signal that receives predetermined number triggers the change between the first and second states, and wherein individual input control signal is separated and is less than this predetermined threshold t from contiguous " short " input control signal mthe time interval, as previously mentioned.In addition, this control section 224 can be configured to, in response to the duration t of each input control signal inall exceed the second predetermined threshold Th l2, cause the change of ratio or the change of merging luminous intensity in response to " length " input control signal, the state of controller 220 is changed to the second state from the first state.
This control section 224 can be configured to, and its luminous intensity is increased or reduced scheduled volume by the light source of controlling separately, causes the change of the luminous intensity of optical element 240a, 240b.Therefore, change in order to produce desired luminous intensity, may need to carry out the many of scheduled volume and continuously change.Especially, this control section 224 can be configured to, as long as control signal continues, make its luminous intensity increase or reduce scheduled volume with predetermined space with regard to repetitive control light source, produce thus the progressively change of the ratio between the first and second light source 240a, 240 intensity, or the progressively change of the merging luminous intensity of the first and second light source 240a, 240b.
Alternatively, replace continuously changing of a series of scheduled volumes with predetermined space of repetitive control, this control section 224 can be configured to the startup that progressively increase or reduce of control with the luminous intensity of the 240a of light source separately, the 240b of the predetermined amounts of predetermined space.This control section 224 can further be configured to the termination that progressively increases or reduce in response to the luminous intensity of the termination control of input control signal light source 240a, 240b separately.
As the variation of method progressively changing that relates to control section 224 and cause the luminous intensity of the first and second light source 240a, 240b, this control section 224 can be configured to, during meeting the cycle of the one or more criterions for adjusting this ratio at input control signal, change between multiple predetermined ratio according to preassigned pattern, adjust the ratio between the luminous intensity of the first and second light source 240a, 240b.Especially, this preassigned pattern can comprise, is relating to from R 1to R 5the example context of five kinds of different predetermined ratio in, by ratio from R iadjust to ratio R i+1and ratio is from R 5adjust to ratio R 1.As another example, this pre-defined rule can comprise, by ratio from R iadjust to ratio R i+1and reaching ratio R 5to relate to ratio from R afterwards iadjust to ratio R i-1until reach this ratio R 1.This adjustment can comprise from up-to-date adjustment or after this adjustment starts (being started by current ongoing input control signal) process predetermined space certainly, by preassigned pattern, current ratio is adjusted to next predetermined ratio, provide thus with predetermined space and change to another by preassigned pattern from a predetermined ratio, and this input control signal continues simultaneously.Multiple predetermined ratio R iand/or preassigned pattern can be arranged to the sequence of ratio values that for example provides following, wherein this ratio changes to a ratio that mainly depends on secondary light source 240b from a ratio that mainly depends on the first light source 240a monotonously, and/or vice versa.As another example, the plurality of predetermined ratio R iand/or the basic randomly changing providing from a ratio to another can be provided preassigned pattern, for example change to another from a light scene, and do not provide by the first and second light source 240a, 240b any one contribution dull or smoothly change.Replace one group of five predetermined ratio using as in above-mentioned example, depend on the requirement of use scenes, can adopt the predetermined ratio of any number, for example any number from 2 to 20 scope.
For increasing or the scheduled volume that reduces the luminous intensity of light source 240a, 240b can be predetermined fixed amount.As non-restrictive example, this scheduled volume can for example be fixed as the predetermined ratio by light source 240a separately, maximum light intensity that 240b provides, 5% of for example (absolute or selected) maximum light intensity separately.Select can cause more accurately and therefore more level and smooth---but generally slower---adaptive light characteristic for the smaller value of scheduled volume, but---but the general more coarse---adaptation of selecting higher value can cause faster.
As another example, this scheduled volume can depend on light source 240a separately, the current light intensity that 240b provides, if light source 240a for example separately, the current light intensity of 240b approaches light source 240a separately, (absolute or selected) minimum light intensity of 240b is (if for example current light intensity is at this light source 240a separately, in 0 to 10% scope of (absolute or selected) maximum light intensity of 240b) or close to light source 240a separately, (absolute or selected) maximum light intensity of 240b is (if for example current light intensity is at this light source 240a separately, in 90 to 100% scopes of the maximum light intensity of 240b), so by application examples as this mode of the less step-length in 1 to 3% scope of (absolute or selected) maximum light intensity separately.On the contrary, larger step-length is for the luminous intensity of medium range, if for example current light intensity is in 10 to 90% the scope of (absolute or selected) maximum light intensity of light source 240a, 240b separately.The photocurrent versus light intensity when adaptation of this step-length causes approaching the end of available light intensity scope slower adaptive.
Replace predetermined ratio or the percentage of (the absolute or selected) maximum light intensity that adopts light source 240a, 240b to determine this scheduled volume, this scheduled volume can be fixing absolute magnitude, and it does not directly have about (absolute or selected) maximum light intensity separately.But, usually, this fixing absolute magnitude is little about (absolute or selected) maximum light intensity separately, be for example about (absolute or selected) maximum light intensity separately 1/10th or less, allow the level and smooth step-length changing of luminous intensity of light source separately to provide.
Preferably fixed intervals of this predetermined space, to provide steady state value and the continuous response to input control signal.The time span of this predetermined space is to be selected to provide the parameter of regulating the speed in view of the expectation of scheduled volume separately as above.As non-restrictive example, this predetermined space can be the value the scope of from 0.01 to 0.3 second, for example 0.1 second.In addition, can select this scheduled volume and this predetermined space, so as in the time period of expecting at the duration t by single input control signal inexceed the second predetermined threshold Th l2and in situation about causing, carry out the adjustment of ratio of luminous intensity and/or the adjustment of the merging luminous intensity of the first and second light source 240a, 240b of the first and second light source 240a, 240b.For example, this desired period can be the scope of from 1 to 5 second, for example two seconds.
Below, provide the exemplary scene about the change of the luminous intensity of the first and second light source 240a, 240b, to further illustrate above some concepts in greater detail.Especially, this exemplary scene relate to use can provide colour temperature 3200K white light the first light source 240a and the secondary light source 240b of light of the about 7000K of colour temperature can be provided.In addition the duration t of single input control signal, inexceed the second predetermined threshold Th l2be assumed that first and do not change this ratio by adjusting the merging luminous intensity of the first and second light source 240a, 240b, subsequently by rely on the duration of input control signal and rely on first and/or the current light intensity of secondary light source 240a, 240b adjust the luminous intensity ratio of the first and second light source 240a, 240b and do not change merging luminous intensity, produce in a continuous manner ratio adjustment and merge luminous intensity adjustment.
In this, the example that Fig. 4 a provides this input control signal is described, merged the relation between luminous intensity and the change of colour temperature.It should be noted that in this example, this colour temperature has reflected the ratio between the luminous intensity of the first and second light source 240a, 240b.The upper figure of Fig. 4 a illustrates as the situation of the switch of being controlled by this button 212 of the function of time using thick line, has therefore indicated the input control signal being received by controller 220.Figure below of Fig. 4 a has illustrated as (relatively) of the function of time and has merged luminous intensity and using thick dashed line, the colour temperature as the function of time be described using heavy line.
The time t being pressed in response to button 212 1the first input control signal starting is short signal, makes thus the control after the first input control signal stops of this controller 220 merge luminous intensity with the maximum of the colour temperature of about 4500K and connects one or more optical elements 240.At time t 2the second input control signal starting is long signal, makes this controller 220 from t 2+ Th l2start to control to reduce and merge luminous intensity until the second input control signal stops, thus cause merging luminous intensity be directed to maximum merge luminous intensity about 55% and do not affect colour temperature.
At time t 3the 3rd input control signal starting is long signal, and first it make controller 220 from t 3+ Th l2starting to control increases merging luminous intensity, until at time t 4reach the maximum luminous intensity that merges.The 3rd input control signal is at time t 5=t 4+ t cTstill continue, thus at time t 4reach the maximum luminous intensity that merges and exceed scheduled time slot t afterwards cT, and make controller 220 change the ratio between the luminous intensity of the first and second light source 240a, 240b, and therefore change colour temperature.Therefore, from time t 5start, this ratio is first adjusted so that higher colour temperature to be provided, and adjusts subsequently this ratio so that lower colour temperature to be provided, then after reaching the minimum colour temperature of about 3200K, adjust this ratio so that higher color temperature to be provided subsequently after reaching the maximum colour temperature of about 7000K.When the first light source 240a provides zero luminous intensity and secondary light source 240b reaches maximum colour temperature when (selected) maximum light intensity is provided, and provide its (selected) maximum light intensity and secondary light source 240b reaches minimum colour temperature when zero luminous intensity is provided as the first light source 240a.This ratio adjustment stops in response to the termination of the 3rd input control signal, thereby produces the colour temperature of about 5200K.
At time t 6the 4th input control signal starting is long signal, makes this controller 220 from t 6+ Th l2start to control to reduce and merge luminous intensity, until the 4th input control signal stops, thereby cause merging luminous intensity be directed to maximum whole luminous intensity about 35% and do not affect the ratio between luminous intensity and therefore affect colour temperature.Finally, at time t 7the 5th input control signal starting is short signal, this controller 220 is controlled after the 5th input control signal stops and disconnected one or more optical elements 240.
The example providing in the background of Fig. 4 a has been supposed or (selected) minimum light intensity maximum in response to (selected) that reach light source 240a, 240b, the stand-by period t expecting win another direction, continue afterwards this ratio adjustment.On the contrary, Fig. 4 b provides explanation according to the example that is related between the change of the ratio (being reflected as colour temperature) of the input control signal of the second exemplary scene, merging luminous intensity and luminous intensity, this the second exemplary scene supposition is maximum or (selected) minimum light intensity in response to (selected) that reach light source 240a, 240b, and ratio is adjusted to another extreme value.
As in Fig. 4 a and Fig. 4 b, upper figure illustrates the situation by button 212 control switchs as the function of time using thick line, and figure below has illustrated as the function of time (relative) merging luminous intensity and using thick dashed line and illustrated as the ratio of the luminous intensity of the function of time and colour temperature thus using heavy line.The duration of the input control signal of the example of Fig. 4 b is consistent with Fig. 4 a example with timing.
In Fig. 4 b in illustrated example, consistent to the response of the first and second input control signals with described in the example background as above illustrating in Fig. 4 a.Meanwhile, described identical with the example that is Fig. 4 a to the response of the 3rd input control signal, until time t 5.Because the 3rd input control signal is at time t 5=t 4+ t cTstill continue, thus at time t 4reach (selected) maximum luminous intensity that merges and exceed scheduled time slot t afterwards cT, this controller 220 is controlled the ratio of adjusting between luminous intensity, and therefore changes colour temperature.Therefore, from time t 5start, this ratio is first adjusted so that higher colour temperature to be provided, and continues subsequently to adjust this ratio from the minimum colour temperature of about 3200K to higher colour temperature after reaching the maximum colour temperature of about 7000K.This ratio adjustment and colour temperature adjustment therefore stop in response to the termination of the 3rd input control signal, thereby produce the colour temperature of about 3700K.Consistent to the 4th with described in the response of the 5th control signal and the background of the example of Fig. 4 a, however after the 3rd input control signal different in the first exemplary scene of the ratio of the luminous intensity of the first and second light source 240a, 240b and the colour temperature therefore producing and Fig. 4.
