[0002] In the current lighting technology field, LED lighting devices have been widely used in various lighting scenarios, such as indoor lighting, commercial displays, and outdoor landscape lighting, due to their high efficiency, long lifespan, and environmental friendliness. With the rapid development of Internet of Things (IoT) technology, people's demand for intelligent lighting systems is increasing, expecting lighting devices to not only provide basic lighting functions but also possess advanced functions such as environmental sensing, remote control, and data interaction.

[0003] Traditional LED lighting devices mostly possess only a single lighting function, lacking effective interaction with the external environment. They struggle to flexibly adjust lighting parameters such as chromaticity, saturation, and brightness according to actual needs, thus limiting their performance and adaptability in specific application scenarios. Furthermore, traditional lighting devices generally lack data interaction capabilities, failing to provide real-time feedback of lighting information to managers or users, thus restricting remote monitoring and adjustment of lighting effects.

[0004] In recent years, although some LED lighting products integrating sensors or simple control functions have appeared on the market, these products are often single-function and unable to achieve complex image acquisition, data processing, and cloud interaction, making it difficult to meet users' needs for highly customized and intelligent smart lighting systems. Especially in application scenarios that require precise control of lighting effects to showcase the true characteristics of the illuminated objects, such as art displays and museum lighting, traditional lighting devices are inadequate.
