Zigbee is a Low‑power, mesh‑network standard with up to 250 kbps data rate and around 10–20 m range per hop. Excellent for scalable, short‑range lighting meshes. Here is how JL-246CG employs these capabilities:
- Functions as ZigBee mesh master controller
- Communicates with up to 50 satellite units (e.g., JL‑245CZ) per network
- Mesh design boosts stability and range via multi-hop relaying
ANSI C136.41 7‑Pin Compatibility
- Uses standard ANSI C136.41 twist-lock interface for NEMA 7-pin
- Dual PC “sandwich cover” offers longer service life and IP67 protection
- Supports 0–10 V dimming and 6 kV surge protection
Best Use Cases
The street light controller works well in a dense city lighting system. In coordinated zones, it allows synchronous dimming by grouping lights. For campus and park networks, it is most recommended due to its scalable and robust ZigBee topology.
What Are the Advantages of Bluetooth-Based Outdoor Photocell Light Sensor JL-244C?
Bluetooth communication is optimized for low‑power usage and close-range (10–100 m), with secure and widely supported communication via mobile devices. Great for setup and maintenance. Here is how this technology works in JL-244.
The JL‑244C pairs with a JL‑244V gateway via Bluetooth. The gateway links to iOS or Android apps. In-app control enables on/off, dimming, and scheduling locally.
Benifits
- Bluetooth uses encrypted connections.
- Compatible with both Android and iOS devices
- Includes a heavy-duty surge arrester of 40 kA.
- Infrared-filtered sensor reduces false triggers
- No cloud or cellular network needed—controls stay local
Its ideal applications include on-site landscape lighting and temporary installations at events or parks.
How Does NB-IoT Photocell JL-246CN Perform in Remote Areas?
These models are equipped with NB‑IoT modules that operate on licensed LTE bands. They are engineered for ultra-low power consumption and long-range signal strength. The NB‑IoT connection allows for direct cloud integration through telecom towers—no need for local gateways. This makes the JL‑246CN and JL‑245CN ideal for remote environments with minimal infrastructure.
Technical Advantages
- Wide-area coverage with a consistent signal.
- Designed for 24/7 autonomous operation.
- Supports both scheduled and sensor-triggered dimming routines.
- Surge protection up to 6 kV; UV-stabilized plastic casing ensures durability.
- 7-pin NEMA C136.41 standard interface, ensuring broad luminaire compatibility.
- Operating range from −40 °C to +70 °C, IP67 weather resistance.
Best Use Case
In mountainous terrain and rural highways, they are best due to their extensive coverage. At the city outskirts or farmlands requiring minimal maintenance, they are good to go.
Why Is LoRaWAN Being Integrated into JL‑246‑L Series?
LoRaWAN supports long-range wireless communication. It uses ultra-narrowband signals with very low power consumption.
The JL‑246CG‑L adds this feature to Long‑Join’s NEMA-compliant photocell. Unlike Wi‑Fi or cellular, LoRaWAN doesn’t send constant data. This makes it ideal where energy savings matter more than speed.
Key Technical Features
- Transmits over distances of 10–15 km in open spaces.
- Battery-friendly and works well in solar or off-grid setups.
- Connects to both private LoRa gateways and national networks.
- Comes in IP67 housing with ANSI C136.41-compliant base.
- Supports both DALI and 0–10 V dimming standards.
- Modular firmware allows future upgrades and OTA updates.
Application Scenarios
It covers large spans without costly wiring or cellular costs, so it’s best to be used in highways and ring roads. In landscape lighting, it monitors scattered fixtures over a unified LoRa mesh, making the operations convenient.
What Does the JL-245CG Offer as a Cat.1-Based Smart Light Sensor?
The JL‑245CG operates on LTE Cat.1, offering a smart middle ground between full 4G and low-speed NB-IoT. It delivers download speeds up to 10 Mbps. Uploads can reach around 5 Mbps.
Despite this, it keeps power use low. Idle consumption is just 1.2 W. Under load, it uses about 2.4 W. This makes it ideal for lighting systems that need moderate data transmission, without draining energy budgets.
Integrated Sensor and Video Feedback Capabilities
This model includes a built-in optical sensor that detects ambient light levels between 350–1100 nm. Peak sensitivity is tuned near 590 nm, enabling accurate dusk/dawn recognition. The unit supports:
- 0–10 V dimming based on real-time lux levels
- Integration with external motion or thermal sensors
- Optional connection to visual monitoring devices (e.g., CCTV units)
- Cloud-synced logging via Long-Join’s platform or third-party API
Suitable Applications
Best to be used in urban surveillance zones as it monitors and controls area lights with real-time sensor input. Its support for video-enabled smart poles makes it highly effective to be deployed in public squares and parks.
When paired with centralized systems like the UM‑9900, the JL‑245CG can contribute both lighting control and environment feedback, ideal for hybrid surveillance setups.
What Can We Expect from the Upcoming 5G Smart Photocell JL-246C-5G?
The JL‑246C‑5G will use 5G NR (New Radio) technology. It will operate in the sub‑6 GHz frequency band. This enables fast deployment in most regions. Latency will stay under 10 milliseconds. Bandwidth will exceed 100 Mbps in real-world use.
Unlike previous generations, the 5G variant will support near-instant response to platform commands and AI instructions. This is essential in environments where timing is critical, such as traffic control, live video integration, and smart energy routing.
Potential for AI and Edge Computing
This model is being designed with edge computing hardware built into the photocell module. That means:
- Local decision-making without always needing the cloud
- Real-time AI-driven actions like dimming by footfall or vehicle detection
- Support for smart algorithms that adjust luminance dynamically
- Buffering and filtering of data before transmission to reduce load
Ideal Use Cases for Smart Cities
Adaptive intersections:
Lights adjust in real time based on traffic flow. They also respond to pedestrian movement.
Event zones:
