Technical Field

[0001] This utility model relates to the field of power electronics technology, specifically to a wireless intelligent lighting driver power supply device with adjustable output voltage and current. Background Technology

[0002] Currently, most smart lighting drivers on the market only support a single wireless communication protocol (such as Bluetooth or Zigbee only), and their output voltage and current are fixed, leading to the following problems:

[0003] 1. Poor compatibility: Different smart home ecosystems (such as HomeKit, Mi Home, Tuya, etc.) require different wireless modules, and users need to replace the driver power supply when changing systems.

[0004] 2. Insufficient flexibility: Traditional driver power supplies cannot dynamically adjust the output voltage and cannot adapt to different LED beads (such as 12V / 24V / 36V) or dimming requirements (such as 0-10V / PWM).

[0005] 3. Limited scalability: Emerging wireless protocols (such as Matter over Thread) are not directly compatible with older devices, making upgrades difficult.

[0006] In summary, a wireless intelligent lighting driver power supply device with adjustable output voltage and current was designed. Utility Model Content
