Embodiment
Please refer to Fig. 2, it is depicted as the circuit block diagram according to the switching device shifter of the light source luminescent modes of the utility model one preferred embodiment.In the present embodiment, switching device shifter 20 receives additional power source 22, and decides the luminescent modes of light source 24 according to the time span that additional power source 22 is closed.
In the present embodiment, switching device shifter 20 is divided into the two large divisions haply: power module 220 and control module 240.Wherein, power module 220 comprises rectification/filter 222 and internal electric source feeding mechanism 224, in order to provide whole device operation required internal electric source according to additional power source; 240 of control modules comprise power supply sampler 242, memory storage 244 and controller 240, decide the luminescent modes of light source in order to the time span of closing according to additional power source.
In power module 220, rectification/filter 222 receives additional power source 22 and power supply after output rectification after rectification/filtering.Internal electric source feeding mechanism 224 receives power supply after the rectifications, and power supply after the rectification is adjusted to internal electric source required when supplying with whole light source device (as control module 240 and light source 24) operation.Wherein, internal electric source feeding mechanism 224 still continues supply internal electric source a period of time after additional power source 22 is closed, so that control module 240 can normally be moved.
In control module 240, power supply sampler 242 can be taken a sample to additional power source 22, and exports corresponding sampled signal according to the result of sampling.Memory storage 244 is in order to store present luminescent modes and/or 24 all luminescent modes that can support of light source of light source 24.246 sampled signals that sent according to power supply sampler 242 of controller judge whether to change present luminescent modes stored in the memory storage 244, and control the luminous of light source 24 according to the present luminescent modes after the decision.
By the utility model can be understood by the person of ordinary skill in the field easilier, please with further reference to Fig. 3, it is the switching flow figure according to the light source luminescent modes of the utility model one embodiment.In the embodiment shown in fig. 3, a plurality of luminescent modes (step S300) that the present luminescent modes of light source at first must be provided and can support this light source, (as step S302～S306), and employed luminescent modes when deciding the control light source with the time span that additional power source is closed is (as step S308～S312) to obtain the pent time span of additional power source afterwards again.
Obtain the pent time span of additional power source in order to reach, a kind of way is to the power supply signal that additional power source is exported take a sample (step S302).If the power supply signal that additional power source is exported more than the degree that can make the normal operation of whole light-emitting device, is then judged additional power source and is normally opened; Otherwise,, think that then additional power source is closed if the power supply signal that additional power source is exported is crossed low and whole light-emitting device is normally moved.In the time of the normal unlatching of additional power source, light-emitting device will continue to check the state (step S304 → step S302) of additional power source; Otherwise, when additional power source is closed, then begin to count pent time span (step S304 → step S306).Though it should be noted that it is the On/Off of checking additional power source in the mode of sampling herein, be not must be during practical operation as limit.For instance, additional power source can remove to control a switch after treatment, if after treatment additional power source can this switch of conducting, judges that then additional power source is unlatching; Otherwise if can't this switch of conducting, then the decidable additional power source be closed.
In case additional power source is closed, and the time span of counting arrived after the default standard, and just whether the time span that can close according to additional power source determines whether changing luminescent modes (step S308) above the scheduled time.Wherein, so-called preset standard can be that additional power source is opened once more, also can be to continue one section gate time.For instance, suppose that the scheduled time is 2 seconds, so, the state that stops to calculate additional power source can be to open additional power source in 2 seconds again, also can be to stop counting automatically after additional power source surpasses 2 seconds closing.In any case, after stopping counting,, the discovery additional power source surpasses the scheduled time if closing, then do not change present luminescent modes (step S310); Surpass preset time if additional power source is closed as yet conversely speaking,, then present luminescent modes is changed the another kind of luminescent modes (step S312) that light source for this reason can use.
For example, suppose luminescent modes that the factory settings light supply apparatus supports as shown in Figure 4, and the aforesaid scheduled time be 2 seconds, then when power supply is opened for the first time, light source is a redness.But during power-off,, then at this moment be regarded as switching to next mode if in 2 seconds, open again---orange, so the present luminescent modes in the mnemon has been changed to orange mode.Otherwise if power supply is to surpass 2 seconds just to open once again, then this kind behavior will be regarded as not wanting to switch to next mode, so light source still rests on red luminescent modes, just need not to change the content of mnemon this moment.Use this kind method, the user is free to switch in the luminescent modes that configures and need not uses complicated button and choose process.
What must pay special attention to is, when additional power source is closed, in order to make normal operations such as counting action, controller and memory storage, internal electric source must continue to keep a period of time, and this section period (as: 3 seconds) is greater than the aforesaid scheduled time (being 2 seconds herein).In other words, even if additional power source is closed, internal electric source also must be maintained in 2 seconds, allow controller confirm whether power supply was opened once again in 2 seconds by the power supply sampler well, and whether decision will switch to next luminescent modes in view of the above.
In addition, utilizing the mode of sampling also the time can be cut, and decide according to the length of on/off time and how to control, for example, is a certain control mode when closing ETAD expected time of arrival and departure in 1 second the time, then is another kind of different control mode between 1 second to 2 seconds.Moreover, also can utilize the mode that decides control several times of opening of closing within a certain period of time.
In sum, switching device shifter provided by the utility model is very simple, and the cost of required increase is also very low, is not that too complicated situation is very suitable for changing mode.
Though the utility model discloses as above with preferred embodiment; right its is not in order to limit the utility model; any person of ordinary skill in the field; in not breaking away from spirit and scope of the present utility model; when doing a little change and retouching, therefore protection range of the present utility model is as the criterion when looking claim institute confining spectrum.
