CYT1000A 理论计算
CYT1000AE 线性恒流 LED 芯片
VF/IF
T1 T2
1、 市电的波形函数是一个正弦曲线（如图 2），表达是如下：
u 2U sin(2ft )
(1)
其中：U:市电有效值，f：市电频率，φ：初始相位
式 1 的逆运算可以求出
T1 arcsin(VF / 2U ) / 2f
T2 1/ 2 f arcsin(VF / 2U ) / 2f
由此可以求出 LED 电流导通时间
(2)
T T 2 T1
（3）
2、 灯珠的 V-I 特性曲线：
由式（2）可以看出灯珠的电压 VF 影响 LED 的导通时间，进而影响 LED 的有
效电流，如下：
VF n *VLED (I LED 600mV / R)
（4）
电阻 R 不同，流经 LED 的电流就不同，所呈现的 VF 就不一样，进而影响 LED
