Why are smart cities turning to Zhaga for street lighting? Because traditional systems lack flexibility and scalability. Zhaga Book 18 changes that by making lighting control truly modular. It connects sensors with wireless modules and LED drivers, ultimately making one plug-and-play system.
The result? Energy-efficient and future-ready streetlights. If you’re exploring intelligent lighting architecture, this guide reveals how Zhaga makes it all possible—one module at a time.
How Does a Fully Modular Zhaga-Based Streetlight System Work?
Жага Книга 18 defines a standardized interface for outdoor LED luminaires and plug-and-play sensor or communication nodes. A luminaire is built with a Zhaga receptacle—sealed and compact—which accepts interchangeable modules (фотоэлементные датчики, communication devices, or blank caps). This creates a future-proof and upgradeable lighting node.
Here is a comparison table outlining key differences between Zhaga Book 18 and the НЕМА interface.
| Особенность | Жага Книга 18 | NEMA 7-контактный |
| Pin Configuration | 4 or 5 pins | 7 pins |
| Форм-фактор | Компактный, малогабаритный | Larger, dome-style |
| Installation Type | Side or top mount | Top mount only |
| Interoperability Focus | Indoor & outdoor smart nodes | Outdoor photocells and sensors |
| Power Output | 24V DC (auxiliary) | 120–277V AC |
| Вариант использования | Smart city, IoT lighting | Traditional streetlight control |
Breakdown of Physical Layers & Interfaces
- Mounting interface: Ø 30 mm twist-lock socket in top or side position.
- Pin configuration: 4-pin (power, DALI‑2/D4i data, auxiliary logic) supplying 24 V DC and bidirectional control.
- Охрана окружающей среды: IP66 rated when a certified module or cap is fitted.
Interaction Between Датчик фотоэлемента, LED Driver & Communication Module
The sensor module, i.e, is a фотоконтроллер, uses the 24 V DC and DALI bus to:
- Measure ambient light or detect motion
- Send dimming commands via DALI‑2
- Transmit data or mesh signals to a network
The LED driver receives DALI‑2 instructions to adjust brightness or report status. A separate communication module like LoRa or Zigbee can be added in a dual-node configuration. All pieces connect modularly: swap a dimming sensor with a communication node—no rewiring needed.
What Functions Does the Zhaga Smart Controller Module Perform?
Ambient Light Sensing for Auto On/Off
The Zhaga uses a built-in outdoor LED light controller photocell to detect ambient light levels. It automatically turns streetlights on at dusk and off at dawn via ДАЛИ или 0–10 V commands. LongJoin’s all products are highly effective in optimizing energy usage.
Motion Detection via PIR or Microwave Sensors
Many modules include PIR or microwave sensors for presence detection. When motion is sensed, they send real-time dimming commands to the driver. For instance, LongJoin’s JL-7 series triggers an instant light boost upon detection and dims when idle.
Wireless Protocol Compatibility
Жага контроллеры света often feature integrated wireless chips. LongJoin modules support Bluetooth mesh through Zhaga Book 18 sockets. They can also be equipped for Zigbee group control and remote settings.
Integration of Optional Sensors
Advanced devices include environmental sensors alongside light and motion detection. LongJoin’s PIR sensor supports daylight harvesting, plus optional modules for temperature or other data. This enables richer analytics and adaptive control behaviors.
Plug-and-Play Capability via Zhaga Book 18 Socket
All functionalities are built into self-contained modules. Install by simply twisting-locking into the Zhaga Book 18 receptacle. Compliance with Zhaga-D4i ensures hot-pluggable upgrades without rewiring.
How Does the Wireless Antenna Module Enable Remote Connectivity?
Communication Standards Supported
The Zhaga antenna module supports multiple LPWAN and short-range protocols. It commonly includes:
- LoRaWAN for kilometers-long links
- Зигби mesh for local group control
- NB‑IoT or LTE‑Cat‑M1 for cellular reach
This diversity lets cities choose the most reliable network for their layout. Here is a table further explaining wireless protocols supported by Zhaga Antenna module.
| Протокол | Frequency Band | Range (Approx.) | Типичное использование | Mesh Support | Потребление энергии |
| Лора | 868/915 MHz | 2–10 km | Long-range smart grid | No | Очень низкий |
| Зигби | 2.4 GHz | 50–100 m | Short-range, mesh networks | Yes | Низкий |
| NB-IoT | LTE bands | 1–10 km | Carrier-based IoT | No | Low–Medium |
| БЛЕ | 2.4 GHz | 10–50 m | Commissioning/config | No | Очень низкий |
Command & Data Exchange with Control Centers
Modules relay DALI‑2 commands and status updates over the air. They receive schedule, dimming, and firmware updates from a central server.
Telemetry, such as voltage, current, power factor, and lamp faults, is sent back. This enables remote diagnostics and proactive maintenance.
Group Lighting Control & Mesh Networking
Zigbee modules form self-healing mesh networks across luminaires.
- LoRaWAN supports star topology with long-range links.
- NB‑IoT manages point-to-cloud setups.
This architecture enables group adjustments for zones, streets, or patterns, without rewiring.
Real-Time Monitoring & Diagnostics
Modules track key metrics such as voltage and power factor. They detect faults and abnormal operations right away. Gateways or cellular links send alerts for fast action. Dashboards display real-time status, logs, and even GPS-based location in supported models.
What Is the Internal Electrical Architecture Behind Zhaga Streetlights?
Power Distribution
Zhaga streetlights receive standard AC power via L (live), N (neutral), and PE (protective earth). Inside, the LED driver converts this to low-voltage DC.
A dedicated 24 V auxiliary output is routed through the Zhaga Book 18 socket to power add-on modules—no separate wiring required.
LED Control Lines
The LED driver outputs to LEDs using LED+ and LED– terminals. These handle high-current DC to control light output. These lines are isolated from the Zhaga socket, enabling safe modular insertion without disrupting LED power.
DALI Signal Lines
Zhaga Book 18 incorporates a two-wire DALI bus (DA+ and DA–) through the socket for digital control. Sensor modules and wireless nodes send lighting commands over DALI‑2/D4i and receive diagnostic data, like errors or power usage.
System Layout Ensuring Modular Plug‑In Compatibility
- The Zhaga receptacle supports four pins: 24 V, DALI, DALI–, and a general-purpose logic I/O.
- It uses a sealed, twist-lock design rated IP65/66, enabling tool-less hot-plug operations and safe module swaps.
- Both luminaires and modules carrying Zhaga-D4i certification ensure full interoperability without any rewiring.
Why Are Cities and Manufacturers Moving Toward Zhaga-Based Systems?
Cities and luminaire makers are adopting Zhaga Book 18 because it simplifies upgrades, reduces costs, ensures interoperability, and delivers proven energy and IoT benefits. Here is a table detailing their key features and their benefits.
| Особенность | Выгода |
