Adjust LED brightness by controlling LED drive power.
In the present invention is implemented, sinusoidal signal that the first second chip detection is processed through copped wave simultaneously counts in preset time
Half wave number lacking in sinusoidal signal in T, then the second chip lack half wave number is changed into corresponding lamplight brightness signal
And LED brightness is adjusted by controlling LED drive power according to lamplight brightness signal.
Embodiments provide a kind of second embodiment of LED lamplight brightness adjusting method, including：
201, the first chip controls chopper circuit from the zero point of sinusoidal signal waveform in preset time T according to switching signal
Place starts to carry out copped wave process, wherein T=t1+t2 to sinusoidal signal, and t1 is the even-multiple in sinusoidal signal cycle, and t2 is preset
The prolongation time less than the sinusoidal signal minimum period；
In the present invention is implemented, the first first chip controls chopper circuit from just in preset time T according to switching signal
Start at the zero point of string signal waveform to carry out copped wave process, wherein T=t1+t2 to sinusoidal signal, t1 is the sinusoidal signal cycle
Even-multiple, t2 is the preset prolongation time less than the sinusoidal signal minimum period；
It should be noted that zero point refers to the intersection point of sinusoidal signal waveform and x-axis, because the first chip may be to sinusoidal letter
The terminating point misjudgment that number copped wave is processed, such as starting point and ending point, all in zero point, all positions in starting point and ending point
In the case of accurately, need to carry out copped wave twice to process according to switching signal, that is, remove two half-waves, and the first chip error
Terminating point is positioned at the right side of exact point (zero point), has actually carried out three copped wave and processed, so by extending copped wave
The time processing is so that the terminating point that copped wave is processed is always positioned at the right side of exact point (zero point), with starting point and ending point all
The situation of accurate positioning is compared, and copped wave number of times adds one, and the half-wave quantity lacking counting afterwards also adds one.
202, the second chip detection through sinusoidal signal that copped wave is processed and counts in sinusoidal signal in preset time T and lacks
Half few wave number；
In the present invention is implemented, control chopper circuit from sine in the first chip in preset time T according to switching signal
Start at the zero point of signal waveform to carry out copped wave process, wherein T=t1+t2 to sinusoidal signal, t1 is the idol in sinusoidal signal cycle
Several times, in addition it is also necessary to the second chip detection is through copped wave after t2 is the preset prolongation time less than the sinusoidal signal minimum period
The sinusoidal signal of process simultaneously counts half wave number lacking in sinusoidal signal in preset time T.
203, the second chip judges to the parity of half wave number lacking；
If half wave number lacking be odd number, the second chip by lack half wave number subtract in the lump using the quantity after subtracting one as
Then final half wave number is changed into corresponding lamplight brightness signal and according to lamplight brightness signal by controlling by final half wave number
LED drive power is adjusting LED brightness；
If half wave number lacking is even number, the second chip by lack half wave number directly as final half wave number, then
By final half wave number change into corresponding lamplight brightness signal and according to lamplight brightness signal by control LED drive power adjust
Section LED brightness；
In the present invention is implemented, the sinusoidal signal that processes through copped wave in the second chip detection simultaneously counts in preset time T
In addition it is also necessary to the second chip judges to the parity of half wave number lacking after half wave number lacking in interior sinusoidal signal；If
Half wave number lacking is odd number, then the second chip subtracts the quantity after subtracting one in the lump lack half wave number as final half-wave
Then final half wave number is changed into corresponding lamplight brightness signal and according to lamplight brightness signal by controlling LED driving by number
Power supply is adjusting LED brightness；If half wave number lacking is even number, the second chip is by lack half wave number directly as
Then final half wave number is changed into corresponding lamplight brightness signal and according to lamplight brightness signal by controlling by half wave number eventually
LED drive power is adjusting LED brightness；Wherein, according to the mode of lamplight brightness Signal Regulation LED brightness can be
By adjusting the supply voltage of LED or the source current adjusting LED, can also be luminous two in regulation LED
The amount of luminescence of pole pipe.
It should be noted that because t1 is the even-multiple in sinusoidal signal cycle, so sinusoidal signal is being carried out at copped wave
In the case of starting point and ending point all accurate positionings of reason, correct copped wave number of times is all even number；When half wave number lacking is
During odd number, illustrate that the starting point that sinusoidal signal is carried out with copped wave process is located on the left of zero point or just in zero point, and step 201
Middle extend the time that copped wave processes and be equivalent to and increased a copped wave number of times, now need to subtract lack half wave number and will subtract in the lump
Quantity after one is as final half wave number；And when half wave number lacking is even number, illustrate to carry out copped wave process to sinusoidal signal
Starting point be located at zero point on the right side of, due to starting point be located half-wave have been turned on, be equivalent to and decrease a copped wave number of times, system
Half wave number lacking of meter also reduces one, and extends the time that copped wave processes in step 201 and be equivalent to and increased a copped wave
Number of times, so half wave number lacking now counting is precisely accurately.
