Description of drawings
Fig. 1 shows the flow chart of steps of preferred embodiment of the present invention.
Embodiment
See also Fig. 1, Fig. 1 is the flow chart of steps of preferred embodiment of the present invention, as shown in Figure 1, the present invention be used to control contain multi-segment brightness can be for the light source of adjusting, the brightness hop count of light source represents that with X the method for adjusting light source is at first opening the switch (S1) of light source, can put bright light source this moment, the brightness of light source is the default brightness (S2) in first rank, is generally the brightest brightness or the darkest brightness, but not as limit.Then close the switch (S3) of light source, after closing the switch of light source, open for the second time the switch (S4) of light source, and calculate from last off switch to the time T 1 of opening switch, if off switch to the time T 1 of opening switch greater than preset time T d, then step will be got back to S2, and just light source can be lighted the default brightness on first rank again.But if off switch to the time T 1 of opening switch less than preset time T d, then light source can be lighted on second rank and to preset brightness (S5).Wherein preset time T d is a fixed value and can adjusts arbitrarily, and the slightly dark or slightly bright default brightness in first rank of the default brightness meeting in common second rank, but not as limit.
When light source was lit in the default brightness in second rank, if be not related to the black out source, then light source can change to the default brightness (S6) in the 3rd rank after through a buffer time Tbuff.
But when light source is lit in the default brightness in second rank, as if reopening (S52) behind the switch (S51) of closing light source again, then can calculate the last time again and close light source switch to the time T 2 of opening light source switch, and relatively whether T2 is greater than preset time T d, if T2 then gets back to the default brightness in first rank that step S2 puts bright light source again greater than preset time T d, if T2 less than preset time T d then light source be fixed on the second default brightness (S53).
Identical, when light source changes to the default brightness in the 3rd rank (S6), if be not related to the black out source, then light source is after through a buffer time Tbuff, can change to the default brightness of quadravalence, change to the default brightness (Sn) in N rank so in regular turn, wherein N equals the brightness hop count X of light source.
When light source is lit in the default brightness in the 3rd rank, as if reopening (S62) behind the switch (S61) of closing light source again, then can calculate the last time equally again and close light source switch to the time T 3 of opening light source switch, and relatively whether T3 is greater than preset time T d, if T3 then can come back to the default brightness in first rank that step S2 puts bright light source again equally greater than preset time T d, if T3 less than preset time T d then light source be fixed on the 3rd default brightness (S63).
When light-source brightness changes to the default brightness in N rank (Sn), if be not related to the black out source switch, light source then can closed (Sn+1) through behind the buffer time Tbuff, if and light source is closed light source when changing to the default brightness (Sn1) in N rank, reopen light source (Sn2) afterwards, then can calculate and close light source, if Tn is greater than preset time T d to the time T n that reopens light source, then light source can be lighted the default brightness on first rank again, and S2 restarts from step.But less than preset time T d, then light source can be lit in the default brightness in second rank as if Tn, and restarts above-mentioned action from step S5.
So repeat above action repeatedly, then, reopen light source again as long as close light source at same order light-source brightness not, and switch to the time of opening light source switch less than preset time T d, then the default brightness of light source igniting before closing so can be controlled light source igniting in different brightness.
Light source brightness control method of the present invention in addition, except controlling the single light source, more can control a plurality of light sources simultaneously, when utilizing a switch to control a plurality of light source simultaneously, because the frequency of oscillation of the timer of each light source has difference, will cause light source to change temporal difference in brightness, becoming a plurality of light sources can't be synchronous in the brightness change.
Therefore, the present invention utilizes 50 and 60 hertz of AC power supplies as the reference power supply in addition, utilizes this reference power source to change the time with the brightness of a plurality of light sources of synchronization, makes the synchronization on brightness changes of a plurality of light sources.
So, just can obtain different light-source brightness,, save unnecessary waste of energy simultaneously, more can prolong the life-span of light source to meet environment requirement by the operation of simple light source switch.
The above only is preferred embodiment of the present invention; so it is not in order to limit scope of the present invention; any personnel that are familiar with this technology; without departing from the spirit and scope of the present invention; can do further improvement and variation on this basis, so the scope that claims were defined that protection scope of the present invention is worked as with the application is as the criterion.
Being simply described as follows of symbol in the accompanying drawing:
