AI Technical Summary
Existing LED lights cannot provide continuous low-intensity illumination after an unexpected power outage or when the lights are turned off. Furthermore, the separate installation of the night light module and the main lighting module results in uneven light emission, which fails to meet the requirements for low intensity and nighttime illumination.
Design a central processing unit comprising a control circuit, an energy storage circuit, and a time-delay conduction circuit to provide power when the external power supply is interrupted, ensuring that the auxiliary LED module is lit, and to achieve afterglow lighting and low-intensity lighting through dual control of the drive circuit and the LED module.
The low-intensity afterglow lighting automatically turns on after the main lighting is turned off, providing stable auxiliary lighting, avoiding chaos caused by sudden power outages, and providing uniform low-intensity lighting during nighttime activities.
