以下结合图1和图2对上述的一种自动钳位补光灯及其光控防抖控制电路的工作原理进行说明：
当环境光变化时，光敏电阻CDS的阻抗特性会随光强变化发生变化。光越强，光敏电阻CDS的阻抗越小，第一电阻R1与光敏电阻CDS串联接电源VCC，分压给第二开关管Q2的基极，第二开关管Q2的基极电压如下公式(1)：
Figure PCTCN2018118189-appb-000001
当环境照度下降时，光敏电阻CDS的电阻值迅速上升，第一电阻R1两端的压降减小，第二开关管Q2的Vb极电压迅速下降，当Vbe达到饱和导通门电压时，第二开关管Q2的E极为低电平，第一开关管Q1饱和导通，使能芯片U1的受控端EN经第二电阻R2、第三电阻R3分压得高电平。当受控端EN电压大于使能电压时，使能芯片U1导通，输出端SW输出电压给第一发光二极管LED1、第二发光二极管LED2，补光灯点亮工作。
使能芯片U1的受控端EN电压如下公式(2)：
Figure PCTCN2018118189-appb-000002
当环境照度上升时，光敏电阻CDS的电阻值迅速下降，第一电阻R1两端压降上升，第二开关管Q2的Vb极电压迅速上升，当Vbe达到截止门电压时，第二开关管Q2的E极为高电平，第一开关管Q1截止，使能芯片U1的受控端EN经第二电阻R2、第三电阻R3分压得为低电平。当受控端EN电压小于使能电压时，使能芯片U1截止，输出端SW截止电压输出，补光灯停止工作。
当环境照度低到触发使能芯片U1工作周期首次输出端SW电压输出时，第三开关管Q3的B极为高电平饱和导通，第四电阻R4与第一电阻R1形成并联分流作用，使第二开关管Q2的Vb极电压深度钳位在低电平状态，避免环境照度小幅波动时，使能芯片U1的 频繁触发开关动作，此时，第二开关管Q2的Vb电压公式(3)如下：
Figure PCTCN2018118189-appb-000003
只有当环境照度上升到满足公式(3)的Vbe达到截止门电压时，第二开关管Q2的E极为才满足高电平，第一开关管Q1截止，使能芯片U1的受控端EN经第二电阻R2、第三电阻R3分压得为低电平，使能芯片U1截止，输出端SW截止电压输出，第三开关管Q3的B极为低电平截止，第四电阻R4与第一电阻R1不再是并联关系，深度钳位解除。
