Abstract
本发明提供一种灯具的调光方法、系统、灯具、电子设备及可读存储介质。该方法包括：基于调光指令参数，输出每路灯珠组的第一功率参数值；基于第一功率参数值，对初始功率参数值进行渐变处理，输出每路灯珠组的第二功率参数值，第二功率参数值用于指示初始功率参数值渐变至第一功率参数值所对应的中间值；基于每路灯珠组的功率阈值和灯具的功率阈值，对第二功率参数值进行缩放处理，输出每路灯珠组的第三功率参数值；基于灯具对应的工作电源的功率阈值，对第三功率参数值进行限流处理，输出每路灯珠组的第四功率参数值；基于每路灯珠组分别对应的PWM频率，对每路灯珠组进行调光控制。本发明提供的灯具的调光方法，通过PWM频率实现对灯具的调光控制。
