PWM调光具有以下优点:
(1)无论调光比有多大,LED-直在恒流条件下工作。
(2)颜色一致性好,亮度级别高。在整个调光范围内,由于LED电流要么处于最大值,要么被关断,通过调节脉冲占空比来改变LED的平均电流,所以该方案能避免在电流变化过程中出现色偏。(3)能提供更大的调光范围和更好的线性度。-PWM dimming has the following advantages:
(1) no matter how much the dimming ratio is, LED- is working under constant current condition.
(2) the color consistency is good, the brightness level is high. In the dimming range, due to the LED current is either a maximum value, or is turned off, by adjusting the pulse duty ratio change led average current
