Traditional IoT street‑light solutions rely heavily on LoRaWAN or PLC gateways for data aggregation. Gateway hardware brings extra procurement cost, site‑by‑site deployment work and potential single‑point‑of‑failure risk for municipal lighting projects.
SWIOTT CTBL501 embedded 4G smart street light controller solves this pain point with cellular direct‑to‑cloud architecture. Every finished unit goes through rigorous mass aging test before delivery, simulating long‑time outdoor running conditions to validate hardware and firmware stability for real‑world smart‑city lighting deployments.
CTBL501 adopts compact IP68 enclosure, specially engineered to fit directly inside street‑lamp housings. No large‑scale cabinet reconstruction is needed for new‑build or retrofit lighting projects.
The device leverages mature 4G‑LTE and 2G‑GSM multi‑band cellular networks. Each street‑light node transmits working data and receives control commands directly to cloud server. There is no requirement for intermediate gateway hardware, simplifying project bill‑of‑materials and reducing on‑site installation workload.
The controller supports industry‑standard 0‑10V precision stepless dimming. Operators can implement three control modes: single‑lamp independent dimming, group‑targeted dimming and full‑network broadcast dimming, with brightness adjustable continuously between 10%‑100%. Built‑in 16A relay supports remote ON/OFF switching for lighting terminals.
High‑accuracy energy metering chip is integrated onboard, eliminating external power meters. It continuously collects real‑time voltage, current, active‑power and power‑factor data with measurement accuracy lower than 2%. Verified energy consumption data supports municipal energy audit, cost analysis, carbon‑emission statistics and data‑driven urban lighting planning.
Automatic fault diagnosis runs in the background continuously. It detects various anomalies within 4 seconds. Critical failures trigger automatic power cut‑off; device will auto‑recover once operating conditions return to normal. Comprehensive hardware protection covers overload, short‑circuit and thermal protection to secure the whole lighting terminal.
Even when cloud network connection drops, the onboard RTC real‑time clock chip keeps pre‑configured lighting schedules executing autonomously, guaranteeing uninterrupted public lighting service. OTA remote firmware upgrade function enables later‑stage feature iteration without site visits.
CTBL501 features wide operating temperature from‑40℃ to +60℃, storage temperature reaches‑40℃ to +85℃, with MTBF exceeding 200 000 hours. The IP68 dust‑proof and waterproof housing copes with heavy rain, humidity and sharp temperature shifts all year‑round.
The product has obtained CE, FCC and CB certifications and complies with EN55015 & EN55022 EMC standards. All products pass strict safety, EMC and mass aging test before shipment for worldwide project deployment.
The full solution consists of web‑based control center, cloud server, cellular network and CTBL501 controllers. Project managers send remote commands from web portal, unify lighting scheduling, collect operational datasets and receive instant fault push alerts.
Typical deployment scenarios: ‑ Urban arterial & suburban road lighting ‑ Highway tunnel lighting ‑ Industrial park & seaport lighting ‑ Commercial complex, municipal park and campus lighting
By deploying CTBL501, city operators gain stable and optimized illumination, reduce lamp downtime and improve road visibility. Intelligent dimming cuts power waste; proactive fault alerts decrease site‑visit frequency and total‑cost‑of‑ownership. Optimized energy consumption lowers city carbon footprint and advances green smart‑city construction goals.
