Description

Technical Field

[0001] This utility model relates to the field of electronic circuit technology, and more specifically to an intelligent LED driver power supply. Background Technology

[0002] In traditional lighting systems, the brightness and color temperature of LED light sources are typically adjusted manually or set to a fixed value. In practical applications, the light requirements in a home differ significantly between morning and evening, while in hospitals, nursing homes, and other similar settings, the sleep quality of patients and the elderly is significantly affected by light levels. While some existing technologies offer simple dimming and color temperature adjustment products, most are single-function and fail to comprehensively consider environmental parameters and human circadian rhythms.
