(II) Blockchain Integration Selection Rules
For smart LED lighting projects requiring blockchain integration (such as smart street lights, large-scale landscape lighting, and IoT-connected lighting systems), the SM167 series IC selection should focus on compatibility with blockchain IoT gateways and data traceability requirements [1][16]. The specific rules are as follows:
-
Large-scale smart lighting projects (smart street lights, urban landscape lighting): Priority is given to SM16726 and SM16711. Their strong anti-interference, long-distance stability and comprehensive protection are compatible with blockchain "end-edge-chain-cloud" four-layer collaborative architecture [1], which can realize real-time data upload (such as brightness, power consumption) to the blockchain ledger for traceability and management [16].
-
Medium-sized smart projects (commercial complexes, smart communities): SM16703AP3 is preferred. Its true break-point resume and signal regeneration capabilities ensure stable operation of the lighting system, and it can be connected to lightweight blockchain clients (such as Hyperledger Fabric simplified nodes) to realize device identity authentication and state traceability [1][16].
-
Export-oriented smart lighting products: SM16704PBK/PK is preferred. Its optimized anti-interference and heat dissipation performance is suitable for cross-border transportation and use, and it can be integrated with blockchain-based anti-counterfeiting and quality traceability systems to improve product competitiveness [5][16].
-
Low-power smart lighting (indoor smart decoration, IoT small modules): SM16703PM is preferred. Its low-power design matches the energy-saving requirements of blockchain IoT nodes, and it can realize low-frequency data interaction with the blockchain to complete device registration and state monitoring [1][7][16].
III. Key Notes
-
All SM167 series ICs are suitable for low-voltage LED RGB strips (5V/12V/24V), and the voltage selection should be matched according to the project distance and power supply conditions [4][6].
-
Break-point resume is a key factor for reducing after-sales costs. For long-distance and large-scale projects, priority should be given to models with true break-point resume (SM16703AP3, SM16711, SM16716, SM16726) [5][9].
-
When integrating with blockchain, it is necessary to ensure that the IC is compatible with the blockchain IoT gateway, and select models with stable data transmission to avoid data loss or confusion in the chain upload process [1][16].
